A P3M Martin in flight, 1930.
|Maker||Glenn L. Martin Company|
|User||United States Navy|
|Main Users||United States Army Air Forces|
In 1929, the US Navy commissioned the aeronautical builder, Glenn L. Martin , to develop a patrol seaplane from the P1M Martin, a seaplane that had already been built by the Naval Aircraft Factory, under license with discreet results.
The P1M, the first prototype, was a 22 m medium wingspan biplane, 14 m long and weighing only 3.9 t when empty. It was powered by two Wright Cyclone engines of 525 hp each, a version called P2M which was very similarly powered by WC engines of 575 hp each. In both cases the cockpit was open. Glenn L. Martin reverse-engineered this latest version to develop the P3M prototype. [ 1 ]
The first nine P3M-1s were not ready until 1931. They were sunshade wing floatplanes with open cockpits (much like the CANT Z.501 ) with open cockpits (some cases were closed) powered by two 450 hp Pratt & Whitney engines, with a 18.8 m long and 30.5 m wingspan. The curb weight was 4.53 t and it had a double tail or double drift mounted on a single tail.
These seaplanes made a good impression on the Navy for their performance and some units remained in service until the start of World War II on nearby coastal patrol. The success of these small seaplanes motivated the development and production of the Martin PBM Mariner in 1937 . | aerospace |

Rising airborne right on the opening of today’s two-hour “launch window” was Indonesia’s Merah Putih-2 communications satellite, destined for Geostationary Transfer Orbit (GTO) and eventually a minimum 15-year operational “slot” at 113 degrees East longitude from which it will deliver up to 32 Gbps of capacity.
Owned and operated by Bandung-based Telkom Indonesia, Merah Putih-2 is the fourth Indonesian communications satellite lofted to orbit by SpaceX, following on the heels of the inaugural Merah Putih in August 2018, PSN-6 Nusantara Satu in February 2019 and most recently last June’s launch of SATRIA. Today’s launch brings to 52 the total number of large geostationary communications satellites on behalf of 20 sovereign nations lifted by Falcon 9 boosters since December 2013.
Also known by the working designator of “HTS-113BT”, Merah Putih-2 is a High Throughput Satellite (HTS) with active-transponder functionality spanning the Ku- and C-bands and destined for eventual emplacement at 113 degrees East longitude. In October 2021, Thales Alenia Space was contracted to build the 8,800-pound (4,000-kilogram) satellite on the skeleton of its tried-and-true Spacebus 4000B2 platform.
“HTS-113BT will strengthen connectivity infrastructure across Indonesia archipelago,” commented Endi Fitri Herlianto, CEO of Telkomsat at the time, “to support digital business by providing better quality of service for Indonesia society.” The satellite left Nice, France, on 9 January and after a seaborne transit across the Atlantic Ocean was unloaded at Port Canaveral on the 24th, ahead of testing, fueling and eventual encapsulation inside the Falcon 9 payload fairing for launch.
“The Merah Putih-2 satellite is a hope as well as a manifestation of Telkom’s commitment to support equitable connectivity throughout Indonesia, complementing our land and sea infrastructure,” said Telkom President Director Ririek Adriansyah. “Telkom believes that equitable access to information is expected to accelerate the digitalization of society in various aspects.”
SpaceX yesterday announced that it was targeting a two-hour launch window from 3:11 p.m. through 5:11 p.m. EST Tuesday to fly Merah Putih-2, with a four-hour backup opportunity opening at 12:53 p.m. EST Wednesday if needed. Weather conditions for both attempts were predicted to be about 95-percent-favorable, with a slight risk of violating the Cumulus Cloud Rule the only issue of concern on Tuesday.
“The overcast rainy conditions will clear out late Monday morning as the low-pressure system, currently to the east, continues to track eastward,” noted the 45th Weather Squadron at Patrick Space Force Base. “Both Tuesday and Wednesday should see favorable weather conditions over the Cape, as high pressure over the central Gulf of Mexico slowly drifts eastward.
“For the launch day, weather conditions are expected to be almost ideal with a slight possibility of a stray cumulus or cirrus cloud during the window,” the 45th concluded. “As such, the likelihood of a weather constraint violation is very low.”
Flying Tuesday’s mission was the B1067 booster core, which previously completed 16 flights between June 2021 and last month; her 17th launch today sets her in fifth place on the list of most experienced Falcon 9 boosters to date.
B1067 first saw service almost three years ago to launch the CRS-22 Cargo Dragon for a month-long stay at the International Space Station (ISS). She went on to deliver eight astronauts from the United States, Germany and Italy to the sprawling orbital complex on Crew-3 in November 2021 and Crew-4 in April 2022, followed by the CRS-25 Cargo Dragon to the ISS the following summer.
Added to this impressive list, B1067 also lifted a geostationary communications satellite for Turkey in December 2021—which helped set a new record (now broken) between pairs of Falcon 9 launches at less than 16 hours—and a pair of O3b mPOWER broadband satellites in December 2022. Other payloads included the Hotbird 13G communications satellite in November 2021 and last June the Satria Very High Throughput Satellite (VHTS), built by Thales Alenia Space for Indonesia’s Pasifik Satelit Nusantara (PSN).
Her Hotbird 13G launch in November 2021 marked the first time that SpaceX achieved 50 Falcon 9 missions in a single calendar year. And in January of 2023, one of her Starlink payloads tipped the scales at 38,400 pounds (17,400 kilograms) to become the heaviest Falcon 9 payload ever orbited at that time.
In readiness for B1067’s latest launch and recovery, the East Coast-based Autonomous Spaceport Drone Ship (ASDS), “Just Read the Instructions”, put to sea out of Port Canaveral on 16 February. And taking full advantage of exceptional weather conditions, the sixth Falcon 9 mission of February went smoothly airborne at 3:11 p.m. EST, with B1067 landing safely on JRTI’s deck about 8.5 minutes later.
Meanwhile, a pair of “burns” by the Merlin 1D+ Vacuum engine on the Falcon 9’s second stage served to deliver Merah Putih-2 to GTO: a first burn lasting six minutes, followed by a 19.5-minute “coasting” phase and a 64-second final burn, ahead of the satellite’s deployment at 34 minutes after launch. Today’s launch was the sixth SpaceX mission of February, following on the heels of two Starlink batches, Intuitive Machines’ IM-1 lunar lander, the highly classified, U.S. Space Force-led USSF-124 and NASA’s Plankton, Aerosol, Cloud, Ocean Ecosystem (PACE). | aerospace |

Flying craft that operate in an atmosphere such as jet aircraft, helicopters, etc... is called being a "Flyer".
Piloting is broken down into three main categories:
- Small Craft are generally under 100 tonnes and are generally used for transportation to and from a surface or between ships. They may also be used for short distance hauling or as fighter/bomber craft.
- Spacecraft are generally between 100 tonnes and 5000 tonnes and are cover the vast majority of ships flying through space.
- Captial ships are above 5000 tonnes and are either very large freigters/tankers or military craft. | aerospace |

The Mars Science Laboratory Atlas spacecraft was launched from Cape Canaveral Air Force Station, Fla., on Nov. 26, 2011. At 1:31 a.m. EDT on Aug. 6, the rover landed on Mars at the foot of a layered mountain inside Gale Crater. Its mission: To investigate whether conditions have been favorable for microbial life and for preserving clues in the rocks about possible past life. It will also study Mars’ habitability.
The $2.5 billion mission set down a large, mobile laboratory using precision landing technology that makes many of Mars’ most scientifically intriguing regions viable destinations for the first time, according to NASA.
Entry, descent and landing included a combination of technologies inherited from past NASA Mars missions, as well as new technologies. The spacecraft was controlled by small rockets and a large parachute during descent through the Martian atmosphere, toward a 4-mile landing zone until the rover separated from its final delivery system, the sky crane. Like a large crane on Earth, the sky crane system lowered the rover to a “soft landing” — wheels down — on Mars’ surface.
For 23 months after landing, Curiosity will analyze dozens of samples drilled from rocks or scooped from the ground as it explores with greater range than any previous Mars rover.
Curiosity is 9 feet, 10 inches long (not counting its robotic arm) 9 feet, 1 inch wide and 7 feet tall at the height at top of mast. Its arm is 7 feet long and its wheels have a 20-inch diameter.
Gale Crater formed when a meteor hit Mars in its early history, 3.5-3.8 billion years ago, according to NASA. The meteor impact punched a hole in the terrain. The explosion ejected rocks and soil that landed around the crater. Scientists chose Gale Crater as the landing site for Curiosity because it has many signs that water was present over its history. Water is a key ingredient of life as we know it.
Inside the 96-mile diameter crater is a mountain that rises higher from the crater floor than Mount Rainier rises above Seattle, according to NASA. The crater is about the size of Connecticut and Rhode Island combined.
Expected near-surface atmospheric temperatures at the Gale Crater landing site during Curiosity’s primary mission (1 Martian year or 687 Earth days) are from -130 degrees to 32 degrees.
Curiosity’s onboard lab will study rocks, soils and the local geologic setting in order to detect chemical building blocks of life — forms of carbon — on Mars and will assess what the Martian environment was like in the past, according to NASA. Just as is the case on Earth, the record of Mars’ climate and geology is essentially “written in the rocks and soil” in their formation, structure and chemical composition.
The rover will use radio relays via Mars orbiters to communicate with Earth’s Deep Space Network. The shortest distance between Earth and Mars is 33.8 million miles, the longest 249.3 million miles. It takes about 13 minutes for a signal to reach Earth.
Advancing the technologies for precision landing of a heavy payload will yield research benefits beyond the returns from Mars Science Laboratory itself. Those same capabilities would be important for later missions both to pick up rocks on Mars and bring them back to Earth, and conduct extensive surface exploration for Martian life.

The space rock named, 2015 TB145, is more than 600 expansive.
The Halloween Asteroid moved towards Earth on past October 31, 2015. Be that as it may, researchers from University of Hawaii discovered this space rock on October 10, 2015.
Presently, the disturbing space shake visits again in November 2018, as it heads towards the Earth. However, it will not come anywhere as close as before for a long time to come. This has intrigued a couple of scientists as they keep an eye out for the Halloween Asteroid.
The Halloween asteroid resembles diminish carbonaceous shooting stars. While, NASA captured a couple of radar images when the asteroid reaches 4,80,000 km of our planet.
Some striking data about its qualities
The space rock’s last experience with earth provided some striking data about its qualities and conduct. The Halloween Asteroid flew by earth at only 1.3 lunar separations which is around 490,000 km and did not represent any risk to planet Earth.
Two years ago, a NASA scientist stated, the NASA’s IRTF (Infrared Telescope Facility) information may show that the question may be a dead comet, yet in the Arecibo pictures it seems to have donned a skull outfit for its Halloween flyby.
While, the rotation time of the asteroid is 2.94 hours, this is the inexact length of its day. The object measures between the range of 625 m and 700 m, and its shape is a marginally flattened ellipsoid, and its rotation axis opposite to the earth at the time of its nearest proximity.
The skull rock is slightly more reflective than charcoal, while it ingests heat is steady with that of other asteroids.
Thomas G Muller, a Max-Planck-Institute researcher said, the visit from the Halloween asteroid will come 71 years from now. The following somewhat even more energizing experience will associate with Halloween’s day in the year 2088, when the protest approaches earth to around 20 lunar distances. | aerospace |

Below us were literally thousands of military airplanes lined up, row after row, neatly arranged by aircraft type. Dozens of gigantic B-52 bombers sat with their wings cut off. Other rows held intact B-1 bombers, C-130s, huge Galaxies, AWACs, and squadron after squadron of F-4s, F-14s, and other fighters. Enough air power to lay waste to entire continents, all just sitting in broad daylight. “We have to go see that!” I exclaimed, and so we did, landing a few minutes later at Tucson International Airport—once again demonstrating the freedom general aviation pilots have in the United States to fly and land almost anywhere at will. Over subsequent visits we discovered how much Tucson has to offer the visitor, especially in the winter months, starting in early November with America’s largest Dia de los Muertos procession. | aerospace |

June 26: Boeing’s F-15 update, the F-15SE ‘Silent Eagle’ designed to be a low-cost alternative to Lockheed Martin’s F-35, is still being developed despite no news released by the company for several months.
It recently completed wind tunnel tests on the Silent Eagle Conformal Weapons Bay (CWB) at its St Louis facility to validate the aerodynamics of the design.
“Boeing and its partners have advanced to the next phase in the development of the Silent Eagle, an evolved derivative of the combat-proven F-15 family of aircraft,” said Roger Besancenez, F-15 Program vice president for Boeing. “We are now testing production-representative hardware as we continue to validate our affordable and low-risk design.”
Boeing is partnering with Korea Aerospace Industries to design, develop and manufacture the CWB. The Silent Eagle is Boeing’s offer in the F-X competition for the Republic of Korea’s multirole fighter aircraft.
More detailed tests later this year will focus on the aerodynamic effects of multiple weapons loads, as well as opening and closing the upper and lower CWB doors.
Boeing this year also completed the final phase of Radar Cross Section (RCS) reduction tests to validate the aircraft’s production configuration. The CWBs can be reconfigured to Conformal Fuel Tanks (CFTs) to optimise the aircraft for longer ranges and increased weapons loading.
Silent Eagle also features enhanced avionics such as an integrated Active Electronically Scanned Array radar and Digital Electronic Warfare Suite. | aerospace |

The earth observatory satellite is designed to help the East African nation gather data for agricultural, mining and environmental protection.
“Ethiopia has joined the effort to seek knowledge and information from space,” Prime Minister Abiy Ahmed, said in a congratulatory message to Ethiopians.
He said that Ethiopia will send up more satellites in collaboration with other countries, without giving details.
“This is a day we became one of the 70 countries in the world that operate a satellite from space,” said Ahmedin Mohammed, an official with Ethiopia’s Innovation and Technology Ministry. “The next step is to launch a communication satellite and also set up a space materials assembly and manufacturing facility here in Ethiopia.”
The total cost of the satellite was $8 million, of which $6 million was covered by China, said Ethiopian officials. Ethiopia hopes to save up to $11 million a year by using their own satellite data.
The satellite was sent into space from Shanxi Province in China. Ethiopian and Chinese officials monitored the launch from a command and control center set up in the outskirts of the capital Addis Ababa. They watched a video stream from China.
Ethiopia’s Prime Minister Abiy Ahmed is credited with starting the satellite program three years ago while he was Minister for Technology. | aerospace |

Kuipersat version 1 and 2, Amazon’s first two satellites, will be finished later this year, and the company hopes to launch both of them early in 2023 using United Launch Alliance’s latest Vulcan Centaur rocket. A joint company between Boeing and Lockheed Martin, United Launch Alliance has been providing launch services to other businesses since 2006.
In the next five years project Kuiper, a new low Earth orbit (LEO) satellite internet service provider, plans to deploy 1,500 satellites. To expand its constellation and provide satellite broadband internet globally, 1 Kuiper aims to launch 3,236 satellites2. If you’re a digital nomad or reside in a remote place, you want to keep a watch on Project Kuiper. Because it claims to bring satellite broadband, or what the Federal Communications Commission (FCC) refers to as the internet, that delivers at least 25 Mbps. Even satellite internet has a higher latency, it can reach places where land-based internet, such as cable and fiber, cannot.
Even yet, none of the Kuiper satellites are operational. Even while Amazon intends to launch its first Kuipersat-1 and Kuipersat-2 prototype satellites in 2023, the whole constellation won’t be online for a while. 3 According to the FCC4’s license for Project Kuiper, the complete constellation of the Amazon company’s satellites must be launched by 2029, with half of them following suit by 2026. Service itself may go live at any point between those dates, according to our estimation.
Engineers on Project Kuiper have constantly using NICE DCV for the past two years. NICE DCV is used by all parties engaged in the ASICs’ design to share data. NICE DCV doesn’t need any additional server resources to function because it is deployed directly on the Amazon EC2 instances that are powering the EDA solutions. When the server portion of the service runs on an Amazon EC2 instance, NICE DCV does not call for a software license, different from many other third-party solutions. As a result, Project Kuiper can save expenses because it only pays for the Amazon EC2 resources it utilizes and not any additional licensing costs.
The IT team can manage NICE DCV’s infrastructure more easily because it is a component of the AWS environment, and AWS supports the service. According to Pereira, adopting NICE DCV is very beneficial in terms of support if you use AWS. You require additional support for a competitor’s tool from the vendor if you install it.
- Streams complicated graphics solutions safely
- Cost-effectively reduces costs by utilizing NICE DCV on Amazon EC2.
- creates and evaluates devices with countless transistors
- Enables remote work without providing each employee with pricey gear
Project Kuiper has effectively carried out the tough research and design tasks remotely using NICE DCV. Remote engineers do not require powerful local workstations, and team members spread to different places have access to the same project tools and data. Using only NICE DCV, the team has already finished creating several kinds of chips. Feel free to visit fortressone.net for updates on projects like Kuiper. | aerospace |

June 6, 2019
The skies over the Innovation Center were buzzing on Saturday, June 1 as dozens of remote controlled planes and drones took to the air during the first annual AeroFest, an open flight and competitive racing event hosted by students in the St. Vrain Valley School District’s aeronautics program.
“As far as I know, this is the largest youth program that we’ve ever put together,” said Richard McCaskill of the Academy of Model Aeronautics, a co-sponsor of the event. “It was all put together—every design, every poster, every invitation, the website—by the students. Other than Jake Marshall, the safety officer, and me, the contest director, the kids are running everything. They’re running the flight lines, and the drone area and the whole bit.”
Students and community members were invited to test their design and build skills in the Open Flight area, and a Build Pit was available for quick repairs or upgrades. A more competitive atmosphere prevailed over at the drone track, as operators raced to maneuver small and large flyers through a series of obstacles. In the Kids STEM Zone, young fliers got a chance to create gliders and learn more about the science of flight and aircraft.
“It’s sort of like an end of the year party,” said Niwot rising senior Caleb Bishop, a student in the aeronautics program. “We’re bringing in the community to show them what we’ve been doing and to share the fun with everybody.” | aerospace |

The data the sensor produces "can be used in fire behavior models. If you know where a fire is and you have prediction model, it can tell you where it's probably going to go. Then you can order up the resources you need to fight the fire."
"More and more teams are seeing the use of getting data because we are having more fires and fires of greater intensity," Zajkowski said. "With the budgets they way they are, you have to do things wisely, you have to fight fire effectively."
The sensor was under development at NASA Ames between 2006 and 2010, used in a limited number of wildfires while aboard NASA's Ikhana drone and B-200 King-Air airplane.
With the sensor now in the possession of the Forest Service, "we would expect to do a lot more," Zajkowski said, noting that it may be used for up to 400 flight hours this year, compared to the 120 hours a year it was used when NASA research protocols had to be followed.
The AMS has other uses as well, and the Forest Service will be marketing it to companies and other government agencies when not in use for firefighting duties.
"We've already flown missions for the USGS (U.S. Geological Service) over Utah Lake where they are monitoring thermal hot springs," Zajkowski said.
In late April, the plane was set to fly a mission for the U.S. Department of Agriculture over a Northern California vineyard where "heat differentials" will be used to to map out soil moisture and provide data for efforts to minimize the among of water that is used on the crops, Zajkowski said.

The airline has shut down operations after it filed for insolvency. Lets have a quick look at what are the recent developments?
Major developments in GoFirst
Indian aviation watchdog Directorate General of Civil Aviation gave a conditional nod to GoFirst Airlines to resume operations with a fleet of 15 aircraft and 114 daily flights.
The airline has some conditions. It will fly some military charter flights to Leh and Thiose Airbase for transportation of military personnels and equipment. The airline won the bid for Ministry of Defense for these flights.
Apart from these, the airline will have to operate check flights for all the aircraft.
Pratt & Whitney soft move
US based aerospace engine manufacturer Pratt and Whitney (P&W) has delivered 2 engines to GoFirst. Delivery of these 2 engines will enable the airline to bring back 1 more aircraft back to operations. After this, the airline will have an operational fleet of 27 aircraft.
The airline is aiming to get 5 more engines by the end of August month. This is because of the direction from Singapore International Arbitration Court (SIAC) to Pratt & Whitney. SIAC ordered P&W to deliver 5 engines every month to GoFirst from August to December.
Pratt & Whitney offers new lease agreement
Engine manufacturer Pratt & Whitney has offered budget airline GoFirst to sign a new and fresh lease agreement. P&W is calling GoFirst to the negotiation table for this new lease agreement. This will include new renegotiated terms and prices for each engine.
Apart from this, the airline is also looking at external funding sources. GoFirst Airlines is reaching out to special-situation financiers such as asset reconstruction companies (ARCs) and distressed debt funds for short term funding.
As of lenders, Bank of Baroda and Central Bank of India have agreed to lend Rs 450 crore to GoFirst.
GoFirst has currently suspended flights till July 25.

Begin your flight instruction today at Eagle County Regional Airport… Here is an interesting article from USA Today regarding the future of Pilot Hiring. I’m guessing this is a good time to learn to fly in order to position yourself for this upcoming hiring frenzy.
After nearly a four-year drought of job openings, the airline industry is on the brink of what’s predicted to be the biggest surge in pilot hiring in history. Aircraft maker Boeing has forecast a need for 466,650 more commercial pilots by 2029 — an average of 23,300 new pilots a year. Nearly 40% of the openings will be to meet the soaring travel market in the Asia-Pacific region, Boeing predicts, but more than 97,000 will be in North America.
"It is a dramatic turnaround," says Louis Smith, president of FltOps.com, a website that provides career and financial planning for pilots. "Pilot hiring was severely depressed in the last three years. The next 10 years will be the exact opposite, with the longest and largest pilot hiring boom in the history of the industry."
The demand for pilots will be so great that the industry could ultimately face a shortage, sparking fierce competition among airlines across the globe vying for candidates qualified to fill their cockpits.
"We’re already seeing in some spots around the world a shortage of pilots … and if you were watching this a few years ago at the last peak, you had airlines stealing from other airlines," says Sherry Carbary, vice president of flight services for Boeing Commercial Airplanes in Seattle. "It’s a global marketplace for pilots, and … we’ll not have enough if that growth trend continues over the next few years. That’s something the industry needs to come to grips with. Where is our pipeline of new pilots going to come from, and how are we going to finance them?"
The hiring surge is being fueled by several factors:
•The rapid growth of travel in Asia, which is on track to surpass North America as the largest air travel market in the world;
•A looming wave of pilot retirements in the USA;
•Proposed changes to rules that could increase the time pilots must train, rest and work;
•And increasing demand for air travel within the USA as the economy improves.
U.S. carriers had 4.9% more pilots in 2010 than in 2009, with much of the increase fueled by low-cost carriers that are continuing to expand, according to the U.S. Department of Transportation’s Bureau of Transportation Statistics.
Low-cost airlines such as Southwest, Virgin America and AirTran increased their pilot staffing 11.2% in 2010 over 2009, while regional carriers increased their pilot numbers by 4.9%. Major network airlines, however, saw their pilot workforce drop 1.3% last year, the bureau says.
"The cost of the fuel has spooked a few carriers," Smith says, noting that the massive earthquake and tsunami in Japan have also had some impact. But, he says, the industry-wide hiring explosion is "still on track."

It is called interplanetary space probe. New Horizons was launched as a part of NASA's new frontiers program. So we get some information about New Horizons.
New Horizons was launched by John S. Hopkins University Applied Physics Laboratory and Research Institute, S.Alan Stern on January 19, 2006 with the primary mission to study Flyby. New Horizons make its closest approach on February 28, 2007, due to a distance of 2.3 meters, 2.3 million kilometers. The main goal of New Horizons is to understand the transformation of the Plutonium System, the Kuiper Belt and the initial solar system.The scientific abilities of New Horizons were very capable, and they worked to return information about the Pluto planet's atmosphere, moons and magnetosphere. New horizons were back online for the encounter on July 6, 2014, due to which the spacecraft began their approach in Pluto on January 15, 2015.
New Horizons has received a lot of data from Pluto planets. New Horizons was largely based on the work of Pluto 350 from Sterns. New Horizons was selected for the official funding in November 2001 as part of the New Frontiers program. New Horizons has the highest peak in the list of the most preferred projects in the medium-sized category.
This spacecraft is known as the first mission in NASA's New Frontiers mission category. This mission is very big and expensive than a Discovery Mission. The cost of launching this mission is approximately $ 700 million in 2001 to 2006. This spacecraft was primarily planned as the journey of the sole inexperienced planet from the Solar System.
This spacecraft has collected the data of Pluto and its Moons meteors and surfaces. New Horizons collected 5000 times more data in Pluto, on Mariner Red Planet. The main goal of this mission was to research Pluto's surface, atmosphere, temperature, additional satellites etc.
The New Horizons body is made up of 0.76 m thick and has a triangle New Horizons is mainly composed of Aluminum. New Horizons have spin-stabilized and three-axis stabilized modes, which are completely controlled with Hydrazine monopropellant. With this spacecraft is communicated by the X band.
New Horizons have an Ultrastable Oscillator Subsystem that is used to study and test pioneer incompatibilities towards the end of the life of spacecraft. The first images of Pluto from New Horizons were obtained during the test of LORRI. This was released on November 28, 2006. New horizons were taken images of Pluto from approximately 4.2 billion kilometers. New Horizons used to use the LORRI to draw the first photographs of Jupiter from a distance of 291 million kilometers.
Most of the new horizons were spent in the hibernation mode across Pluto's journey. New horizons have been called the fastest spacecraft ever. Because it is found to leave the Earth at 16.26 kilometers per second. The surface of this spacecraft is cooled down to the CDC by an inactive radiator on the face of the ant solar. Due to which the difference in temperature is insulated, and separating from the remaining structures is necessary. New horizons have 208.3 mm retrofit-charity mirrors and the metering structure is made of silicon carbide.
New Horizons Plasma and High-Energy particles form one of the two instruments containing spectrometer suites (PAM), which is a toroid electrostatic analyzer of Pluto (SADP) around the Pluto (SADP) and maintaining a potential analyzer (RPA), while the other is PEPSSI. | aerospace |

Many state legislatures are debating if and how UAS technology should be regulated, taking into account privacy concerns, the benefits of their use and their potential economic impact.
In 2013, 43 states introduced 118 bills and resolutions concerning UAS issues. So far, 16 bills have been enacted in 13 states and 14 resolutions have been adopted in 10 states. Common issues addressed in the legislation include defining what a UAS or drone is, their use by law enforcement or other state agencies, their use by the general public, the formation of study committees and Federal Aviation Administration (FAA) test site application process.
The 2012 Federal Aviation Administration Modernization and Reform Act includes “language” requiring the FAA to “establish a program to integrate unmanned aircraft systems into the national airspace system at six test ranges.” Several states, including *Arizona and *California, have introduced resolutions supporting their state’s efforts to be chosen as a test site. Also, *Maryland, *Nevada and *North Dakota have legislatively appropriated funds for the development and potential operation of a UAS test site.
*[Unfortunately, in the State of California, the Hearing Committee of this bill and opposition to it, has been repeatedly ‘postponed,’ and ‘Held under submission’ since 5/24/13]
As of July 2012, 201 authorizations have been made for 106 government entities, law enforcement and others to operate UASs. A recent FAA list, spurred by a Freedom of Information Act lawsuit, indicates that an additional 81 public entities have applied to the FAA for authorization to use UASs. More information about the FAA’s programs and initiatives can be found here.
2013 State Enactments (Listed Alphabetically)
Florida SB 92 defines what a drone is and limits their use by law enforcement. Under this legislation, law enforcement may use a drone if: they obtain a warrant; there is a terrorist threat as determined by the United States Secretary of Homeland Security; or a law enforcement agency determines “swift action” is needed to, among other things, prevent loss of life or serious property damage, or to search for a missing person. The law also enables someone harmed by an inappropriate use of drones to “pursue civil remedies” and prevents evidence gathered in violation of this code from being admitted in any Florida court.
The Hawaii Legislature passed SB 1221, which appropriates $100,000 in funds for two staff positions, contracted through the University of Hawaii, to plan for the creation of three degree and training programs on advanced aviation. One of the programs is a professional unmanned aircraft systems pilot program administered through Hawaii Community College.
On April 11, 2013, Idaho became the second state to enact a drone law. SB 1134 defines an “Unmanned Aircraft System,” requires warrants for their use by law enforcement, establishes guidelines for use by private citizens and provides civil penalties for damages caused by improper use.
Illinois has enacted two UAS bills in 2013. Both new laws define “drone” as any aerial vehicle that does not carry a human operator. Illinois HB 1652 prohibits anyone from using a drone to interfere with hunters or fisherman. SB 1587 allows drones to be used by law enforcement with a warrant, to counter a terrorist attack, to prevent harm to life, or to prevent the imminent escape of a “suspect among other situations.” If a law enforcement agency uses a drone, the agency must destroy all information gathered by the drone within 30 days, except that a supervisor at the law enforcement agency may retain “particular information” if there is reasonable suspicion it contains evidence of criminal activity.
The law also requires the Illinois Criminal Justice Information Authority (CJIA) to report on its website every law enforcement agency that owns a drone and the number they own. Each law enforcement agency is responsible for giving this information to the Illinois CJIA.
Maryland’s legislature, through HB 100, appropriated $500,000 for the state’s unmanned aerial system test site.
Montana SB 196 limits when information gained from the use of unmanned aerial vehicles may be admitted as evidence in any prosecution or proceeding within the state. The information can be used when it was obtained pursuant to a search warrant, “or through a judicially recognized exception to search warrants.” The new law defines “unmanned aerial vehicle” as “an aircraft that is operated without direct human intervention from on or within the aircraft,” not including satellites.
*Nevada AB 507 appropriated $4,000,000 to the interim Finance Committee for allocation to the Governor’s Office of Economic Development for the Unmanned Aerial Vehicle (UAV) program. The funds can only be appropriated if Nevada is selected as a Federal Aviation Administration test site.
North Carolina SB 402 places a moratorium on UAS use by state and local personnel unless the use is approved by the Chief Information Officer for the Department of Transportation (CIO). Any CIO granted exception has to be reported immediately to the Joint Legislative Oversight Committee on Information Technology and the Fiscal Research Division. The CIO may determine that there is a need to develop a UAS program within the State of North Carolina. This effort must include the CIO and the Department of Transportation Aviation Division Director.
*North Dakota law, SB 2018 grants $1 million from the state general fund to pursue designation as a Federal Aviation Administration unmanned aircraft systems test site. If selected, the law would grant an additional $4 million to operate the site.
Oregon’s HB 2710 defines a drone as an unmanned flying machine, not including model aircraft. The law allows a law enforcement agency to operate a drone if it has a warrant and for enumerated exceptions including for “training purposes.” It also requires that a drone operated by a public body be registered with the Oregon Department of Aviation (DOA), which shall keep a registry of drones operated by public bodies. The law grants the DOA rulemaking authority to implement these provisions. It also creates new crimes and civil penalties for mounting weapons on drones and interfering with or gaining unauthorized access to public drones. Under certain conditions a landowner can bring an action against someone flying a drone lower than 400 feet over their property.
The law also requires that the DOA must report to legislative committees on the status of federal regulations and whether UAV’s operated by private parties should be registered in a manner similar to the requirement for other aircraft.
Tennessee law SB 796 addresses the use of drones by law enforcement. The new law enables law enforcement to use drones in compliance with a search warrant, to counter a high-risk terrorist attack, and if swift action is needed to prevent imminent danger to life. Evidence obtained in violation of this law is not admissible in state criminal prosecutions. Additionally, those wronged by such evidence can seek civil remedy.
*Texas recently enacted HB 912, which enumerates 19 lawful uses for unmanned aircraft, including their use in airspace designated as an FAA test site, their use in connection with a valid search warrant and their use in oil pipeline safety and rig protection. The law creates two new crimes, the illegal use of an unmanned aircraft to capture images and the offense of possessing or distributing the image; both offenses are class C misdemeanors. “Image” is defined in the law as any sound wave, thermal, ultraviolet, visible light or other electromagnetic waves, odor, or other conditions existing on property or an individual located on the property. Additionally, the measure requires the Department of Public Safety to adopt rules for use of UAS by law enforcement and mandates that law enforcement agencies in communities of over 150,000 people make annual reports on their use. Texas HCR 217 altered reporting requirements from the original HB 912.
On April 3, 2013, Virginia enacted the first state drone laws in the country with the passage of HB 2012 and SB 1331. The new laws prohibit drone use by any state agencies “having jurisdiction over criminal law enforcement or regulatory violations” or units of local law enforcement until July 1, 2015.
Numerous exceptions to the ban are enumerated including enabling officials to deploy drones for Amber Alerts, Blue Alerts, use by the National Guard, by higher education institutions and search and rescue operations. The enacted bills also require the Virginia Department of Criminal Justice Services and “other state agencies” to research and develop model protocols for drone use by law enforcement in the state. They are required to report their findings to the General Assembly and governor by Nov. 1, 2013.
2013 Adopted Resolutions
*The Alaska Legislature has adopted a resolution this year, HCR 6, creating a legislative Unmanned Aircraft Systems Task Force tasked with reviewing Federal Aviation Administration regulations on drones and creating written recommendations and legislation that “protects privacy and allows [for] the use of unmanned aircraft systems for public and private applications.”
In addition to members of the legislature, the task force will be comprised of a member representing the commissioner of public safety; the adjutant general of the Department of Military and Veterans’ Affairs; the Alaska Center for Unmanned Aircraft Systems Integration at University of Alaska Fairbanks; the Academy of Model Aeronautics and the state Aviation Advisory Board. The task force must provide an initial report of its findings by Jan. 15, 2014, and a final report by July 1, 2014.

Boeing calls it CHAMP -- the Counter-electronics High-powered Microwave Advanced Missile Project.
It’s a new missile that can take out electrical and data systems byemitting high powered microwaves “without causing injury or collateral damage” as it flies over targets.
After months of testing, Boeing announced this week that CHAMP could be a viable weapon for U.S. forces.
“This technology marks a new era in modern-day warfare,” said Keith Coleman, CHAMP program manager for Boeing Phantom Works.
The announcement comes after CHAMP’s first fully operational flight test last Tuesday where the missilesuccessfully disabled a room full electronics, including computers and surveillance cameras.
Much of the details of CHAMP are most likely classified, but Boeing hasreleased a short video that includes an animation of CHAMP being deployed from a Stealth Bomber over an urban area.
In part of the video showing results from an earlier test, computers went dark and cameras went offline seconds after a blast of high power microwaves from CHAMP.
“We know this has some capabilities and some impact and so we’re really trying to engage the customer and see if there’s a way to get this fielded and implemented sooner than later,” James Dodd, Vice President, Advanced Boeing Military Aircraft says in the video. | aerospace |

KAMLOOPS – A pilot flying a B.C. Wildfire plane carrying a load of retardant had to make an emergency landing at Kamloops Airport this morning.
The pilot reported a mechanical issue, turned off the damaged engine and returned to the airport where the plane landed safely.
The plane, a Convair 580, landed with one functioning engine around 8:30 a.m. after dumping the retardant at a fire in the Kamloops Fire Centre. Navi Saini, a fire information officer with B.C. Wildfire says the cause of the issue has yet to be determined.
“We still have engineers working to figure out what had happened,” she said.

Moving beyond the meticulous and time-intensive traditional surveying methods, drones ascend to provide high-resolution aerial data with remarkable efficiency. The core of the debate rests on the accuracy of UAV surveys. Here’s the expert breakdown.
Harnessing Advanced Technology for Enhanced Accuracy
The sophistication of drones is evident through their integration of high-end sensors, cameras, and GPS systems. These components work in unison, offering the ability to acquire data from otherwise inaccessible locations. The implementation of Real-Time Kinematic (RTK) systems further elevates accuracy, refining satellite data in real-time to achieve pinpoint location accuracy down to the centimetre.
The Role of Ground Sample Distance (GSD)
A critical factor in the accuracy of UAV surveys is the Ground Sample Distance (GSD). This metric represents the distance between the centres of two consecutive pixels on the ground. A lower GSD correlates with higher-resolution imagery and, subsequently, more accurate measurements. State-of-the-art drones boast a GSD as low as 1-3 cm, rivalling and sometimes surpassing traditional surveying methods.
Photogrammetry: The Backbone of Drone Surveying
Photogrammetry, or the art of extracting measurements from photographs, is paramount in UAV surveys. It involves the intricate process of merging overlapping photographs taken by drones into comprehensive 3D models and maps. The accuracy of these models heavily relies on the quantity and quality of images captured and the processing prowess of the photogrammetry software.
Navigating Environmental Challenges
The accuracy of UAV surveys isn’t immune to environmental elements like wind, lighting conditions, and satellite visibility. Strong winds can compromise drone stability, whereas inadequate lighting might degrade image quality. Limited satellite visibility can also affect the accuracy of GPS readings. Nonetheless, modern drones come fortified against these challenges, featuring stabilisation and advanced GPS functionalities.
The Indispensable Human Touch
Despite the leaps in technology, the skill and experience of the surveyor operating the drone remain indispensable. Accurate UAV surveys are the product of meticulous planning, accurate execution, and thorough data processing. This involves establishing optimal flight paths, ensuring adequate image overlap, and employing ground control points for data calibration.
Benchmarks of UAV Surveying Accuracy
Empirical studies have positioned the accuracy of UAV surveys within a 1-5 cm range for horizontal measurements and vertical measurements in comparison to conventional techniques. While this level of accuracy may not suffice for certain engineering tasks, it’s exceptionally accurate for the majority of surveying jobs.
UAV surveys stand at the forefront of surveying, offering a blend of efficiency, safety, and accuracy. While various factors can impact their accuracy, continuous advancements in drone technology are constantly pushing the boundaries of their reliability. For a broad spectrum of surveying tasks, the accuracy of UAVs doesn’t just meet the mark; it often exceeds traditional methods, heralding a new chapter in surveying where the limits are as boundless as the sky above.
1. What technological advancements contribute to the accuracy of UAV surveys?
Innovations like advanced sensors, high-resolution cameras, RTK systems, and sophisticated photogrammetry software significantly enhance the accuracy of UAV surveys.
2. How does Ground Sample Distance (GSD) affect the accuracy of drone surveys?
A lower GSD indicates a higher resolution image, which leads to more accurate measurements from the drone-captured imagery.
3. Can environmental conditions affect the accuracy of UAV surveys?
Yes, factors like wind, lighting, and satellite visibility can influence the accuracy, but modern drones are equipped to mitigate these challenges effectively.
4. Why is the surveyor’s expertise crucial in UAV surveying?
The surveyor’s experience ensures proper flight planning, data capture, and processing, which are vital to achieving accurate survey results.
5. Are UAV surveys accurate enough for all types of surveying tasks?
While UAV surveys provide excellent accuracy for most surveying tasks, certain engineering applications may require additional traditional surveying methods. | aerospace |

The difficulty lies much more in recognizing interpretable pixels in several hundred thousand-satellite pictures. He and his research colleagues thus tinkered for several years on algorithms that search for such pixels in the pictures and determine from their colour the quantity of algae, turbidity or quantity of blue algae. “Because the satellites deliver not only snapshots but also pictures taken at high resolution over a longer period, environmental changes can be more clearly recognized than with ordinary sampling,” adds Odermatt.
As of 2012, the satellite Envisat is no longer sending out pictures, as communication with the earth station ceased suddenly for unknown reasons. But since 2015 several follow-on satellites orbit the earth, and these shoot pictures even more often and with higher resolution than Envisat. Thanks to this constant satellite monitoring, it will be possible in the future to get information about the condition of lakes all over the world in real time. | aerospace |

LAS CRUCES- New Mexico State University Air Force and Army ROTC will hold the 114th annual Pass-in-Review ceremony at 4 p.m. Thursday at Pride Field on the NMSU Horseshoe.
Two flyovers of vintage World War II aircraft will take place at 4:10 p.m. by War Eagles Air Museum pilots Floyd Draper and Dan Taylor. The event will also feature a static display of an HH-60 Pave Hawk special operations helicopter from 11:30 a.m.-2:30 p.m. in front of Hadley Hall.
The original purpose of Pass-in-Review was to parade the forces before the commanding general to indicate a troop’s readiness to go into battle. Now, the tradition is a formal military ceremony that displays the strength and unity of a detachment, while also promoting teamwork and pride within an organization, according to a news release from New Mexico State University.
“It allows the university president, or his representative, to review the progress, training and achievements of the cadets in both corps,” said Lt. Col. Jeremiah Klomp, NMSU Air Force ROTC commander and professor of aerospace studies in the College of Arts and Sciences. “It also provides the cadets a chance to demonstrate what they have learned and what they have become to their fellow students, classmates, families and friends.”
NMSU Executive Vice President and Provost Dan Howard will serve as the reviewing official.
Following the parade, NMSU ROTC will hold an awards ceremony in Room 125 of the Hardman-Jacobs Undergraduate Learning Center.
“This awards ceremony provides an opportunity to recognize achievements by cadets in both Air Force and Army detachments, and affords community members a venue to recognize and reward outstanding performance through scholarships and other awards,” Klomp said.
Both ceremonies are open to the public. Free visitor parking passes are available from the NMSU parking website at http://auxadminforms.nmsu.edu/ParkingForms/ePermit.aspx.

Ret. Maj. John M. Vice won the 2014 AIAA (American Institute of Aeronautics and Astronautics) Survivability Award.
He is a leader in the knowledge of reducing aircraft combat vulnerability, battle damage assessment and repair of the planes.
AIAA says he has been recognized as a role model and mentor to young engineers in his field. Vice has been a member of this organization since 1969 and is now an Associate Fellow.
Vice was retired from the Air Force after more than 20 years of service. He joined the Air Force at the age of 19 in 1963. He was given the opportunity to attend college at the University of Wyoming, and graduated with a degree in aerospace engineering with honors.
Next he was sent to receive his master's degree in aerospace-mechanical engineering from the Air Force Institute of Technology in Dayton, Ohio. He served as Air Force Logistics Command's survivability program manager after graduating.
He has written 26 publications on aeronautical testing, damage and repair. Many of his earlier studies were on the F-16 Fighting Falcon and the Lockheed Martin F-22 Raptor. After his retirement, Vice attained several leadership roles in this field as manager, director and consultant of companies. Vice is now semi-retired and working with a company he helped to create in 1997, Skyward, LTD.
The company contracts with major aircraft companies and the U.S. Government, and prides itself on producing customized client solutions.
Vice and his wife, June, moved to Tryon Estates in November 2013. The couple moved to the mountains in 2002 after his wife and daughters vacationed in Asheville, N.C., and fell in love with the area.
Vice likes to hike the trails of the mountains and immediate area with his wife. He still is involved and attends the First Baptist Church of Hendersonville.
One of his greatest joys has been working with the youth in the church. The "Imagine Campaign" was his main focus. He helped them raise enough money in three years to pay off a large debt the church owed. Golf is how he spends time with the men of the church each Monday. | aerospace |

The new route appeals to Oregon companies with European operations, such as Nike and Wieden+Kennedy. It could force Lufthansa to lower its fares between PDX and Frankfurt, Germany.
Douglas Steenland, Northwest Airlines chief executive, plans to announce the new flights on Tuesday during an invitation-only brunch at Portland International Airport, sources familiar with the plans told The Oregonian today. A spokesman for the airline company would not confirm news of the flights, or provide details on a launch date or frequency.
Amsterdam is a major airline hub, offering connections throughout Europe and beyond. For that reason, "the flight will be a barn-burner," says airline analyst Michael Boyd, president of the Boyd Group in Evergreen, Colo.
Oregon trade officials expect the flights to help Oregon companies sell products in Europe. State exports to Europe are already rising, as the falling dollar makes U.S. goods cheaper there. The weaker dollar, however, makes travel more expensive for American tourists.
The new flights are a coup for PDX, augmenting its international service. An average of 79 flights a week leave PDX for destinations abroad. Two-thirds of those flights, however, head to nearby Vancouver, B.C.

The International Space Station, often known as the International Space Station, is a space research station or research center located in near-Earth orbit. The project began in 1998 and will be completed in 2011. The ISS will be the largest man-made satellite ever created at the time of its launch. The International Space Station (ISS) is a collaborative initiative of various space agencies from around the world.
NASA is collaborating with Russia’s Russian Federal Space Agency (RKA), Japan’s Aerospace Exploration Agency (JAXA), Canada’s Canadian Space Agency (CSA), and European countries’ United European Space Agency (ESA). In addition to these, the Brazilian Space Agency (AEB) has some contracts with NASA. Similarly, with slightly different contracts, the Italian Space Agency (ASI) is used.
The ISS will be visible to the naked eye after it is put in low Earth orbit. It will circle 350 kilometers above Earth at a speed of 27,724 kilometers per hour, completing 15.7 rotations every day. Since November 2000, when the last ISS was launched into orbit, there has been a continual human presence on board. There are three people in it right now. It will be able to accommodate six people in the future. The International Space Station functions as a space observatory. It has a number of advantages over other spacecraft, including the ability for people to work in space for longer periods of time.
ISS Full Form
ISS: International Space Station
Orbital station is another name for space station. It was designed with all of the necessities for human survival in mind. That is to say, it is a man-made space station from which a spacecraft can depart from Earth. Aside from that, it has enough capability to land a spaceship on it. They are exclusively installed in the Earth’s low-orbit orbit. Let me explain what a space station is. It is a kind of platform from which the planet can be viewed and the secrets of the sky discovered.
What is the total number of space stations in the world?
The International Space Station (functioning and permanently manned) and China’s Tiangong-2 are the two space stations in orbit as of April 2018. (operational but not permanently inhabited). The Almaz and Salyut series, Skylab, Mir, and, most recently, Tiangong-1 are all examples of previous stations. The space station was erected in orbit to allow scientists to work in space for extended periods of time.
What is the International Space Station, and what does it do?
It is not incorrect to describe it as a space-based laboratory for new technology, astronomical, environmental, and geological study. Scientists have developed a station in orbit from which they can study space in more detail. The International Space Station was launched into orbit in tiny sections into space. The first module was released in Russia’s Zarya module in 1998. Since November 2, 2000, astronauts have been working continuously in this station. It contains a large number of solar panels and weighs approximately 391000 kg. It is in this space station that six astronauts will be able to spend six months.
The space station flies at a distance of around 248 miles (400 kilometers) from Earth. It travels around our planet at a speed of 17,500 miles per hour in 90 minutes. Do you realize that a day covers the same distance as it takes to travel from the earth to the moon and back? If the position of the space station is known, it can be seen as a bright moving light from Earth with the naked eye.
This project involves NASA, Russia’s Roscosmos State Corporation, the European Space Agency, Canada’s Space Agency, and Japan’s Aerospace Exploration agency. The International Space Station has been visited by 230 people from 18 different countries. Kalpana Chawla and Sunita Williams, both from India, have done research on the subject. Peggy Whitson achieved the record for the longest duration spent living and working in space on September 2, 2017, with 665 days. In the entire station, there are only two bathrooms.
The astronauts’ and laboratory animals’ pee is filtered back into the station’s drinking water supply, ensuring that there is never a water shortage. The electrolysis process provides oxygen to this station. After the Moon and Venus, this space center is the third brightest in the night sky. A space walk occurs when an astronaut exits the vehicle and walks into space at any moment. Do you know that Russian cosmonaut Aleksey Leonov performed the first space walk on March 18, 1965? | aerospace |

Lidar test image
22 February 2012
This car was not snapped with a camera but scanned by a 3D imaging lidar, the laser equivalent of radar. ESA is developing the sensor as a navigation aid for exploring deep space.
Lidar stands for ‘light detection and ranging’, with a pulsed laser beam scanning targets by measuring the time it takes for the light to bounce back.
ABSL prototype lidar
Laser ranging is already used for rendezvous and docking in orbit. When ESA’s ATV cargo ferry docks with the International Space Station it bounces laser beams off reflectors on the orbital outpost to judge the distance to within a couple of centimetres.
For missions deeper into our Solar System, ESA hopes to use 3D imaging lidar to build up a complete picture of targets such as a boulder-strewn surface.
This would be like a stereoscopic imager but it would also work in total darkness or blinding sunlight.
ATV uses lasers for docking
“The first is for the guidance, navigation and control of planetary landers, in particular in selecting a safe landing site.
“The second is for steering rovers on planetary surfaces, and the third is for docking in planetary orbit. That would be essential for the proposed Mars Sample Return Mission, for example, when the ascent module carrying material off the martian surface will have to be tracked and captured by its mother craft waiting in orbit.
Lidar test 5km across the Saale Valley
“The challenge is to produce a new class of imaging lidar, much smaller and needing less power.”
Reflecting the technical difficulties involved, separate designs were developed in parallel by two consortia, one led by Jena-Optronik in Jena, Germany and the other by ABSL in Culham, UK.
The shoebox-sized imaging lidars rely on a steerable scan mirror that flicks the laser beam across the target, with a highly sensitive light detector capable of measuring the returning beams from up to several kilometres away.
Jena-Optronik prototype lidar
The two designs aim at different guidance and navigation applications. The German-led unit demonstrates a future rendezvous sensor, while the British-led design is intended to help a lander touch down safely on a planet, detecting and avoiding hazards.
ESA Lunar Lander
Building on this progress, a landing lidar is now being designed for ESA’s Lunar Lander, planned to touch down at the lunar south pole in 2019.
The engineers are also looking at ways of making the lidars even smaller perhaps by using new types of detectors and micro-mechanical optical mirrors.
“It is expected that we can reduce the mass and power consumptions of current commercial imaging lidar systems by at least 70%,” Joao concludes.
B)Various Thoughts on the Flagship Mission
One of the readers of this blog sent me a note asking why it will take almost 11 years to launch the just selected Jupiter Europa Orbiter (JEO) mission. I have not followed all the ins and outs of this, but I’ll share what I think I understand. Normally, a new mission takes approximately four years to develop after it receives a new mission start. Prior to that, it is common to spend some time in pre-start mission development. If money was no issue, it would be reasonable to expect that JEO would launch in the mid 2010s. A 2007 study of a Europa Explorer (the predecessor concept to JEO) presumed the launch would be in 2015. If you look at NASA’s expectation for launching the Flagship mission a year ago, the target date was 2016-2017.
After that time, NASA slipped the launch date to around 2020. The stated reason was to align NASA’s schedule with ESA’s schedule, which could not fit a launch before that into its funding profile. I suspect that the looming cost overruns of the Mars Science Laboratory might have made the delay on NASA’s side inevitable. In any case, now that the MSL cost overrun is on the books, funding for preliminary studies of JEO are slim for the next couple of years. So, we have a 5 year push out in expected launch date over the last two years.
Could NASA pull in the JEO schedule if ESA does not select its potential contribution, the Jupiter Ganymede Orbiter (JGO) in 2011 to fly? Potentially. However, I suspect that it will take awhile for NASA to work through the problems created by the MSL slip and the earliest launch probably would be in the 2018 timeframe at best. Without access to NASA’s funding expectations, this is speculation, however.
On another topic, what if ESA doesn’t select JGO? How might the JEO mission change? The major loss from JGO would be the intense set of flybys of Callisto and the study of Ganymede from orbit about that moon. JEO has an excellent set of instruments for studying the moons of Jupiter during flybys. In fact, a series of flybys are planned of all four Galilean moons. JEO cannot carry enough fuel to orbit Ganymede as well as Europa, so the study of Ganymede from an orbiter would be lost. On the other hand, JEO could delay its orbit insertion at Europa to allow more time for more flybys of other moons. (More flybys than the planned handful at Io are probably out because of radiation issues.) JGO would spend approximately a year conducting 19 flybys of Callisto. JEO could spend an additional year carrying out flybys of either Callisto, Ganymede, or both. If such a plan was implemented, I would expect Ganymede to receive the lion’s share of additional study. The scientific community has prioritized further study of Ganymede over Callisto.
Jason Perry has posted another excellent analysis on his website (see C)about what the selection of JEO with its planned Io flybys would mean for the proposed Io Volcano Observer (IVO). He correctly points out that IVO would conduct more flybys (at least 7, probably 14, and possibly even more) compared to JEO’s 4. The flyby geometry selected for IVO would also be more optimised than JEO would be have. (JEO will use the Io flybys in part ot set up later encounters with other moons and hence is constrained in the selection of flyby geometries.) Jason points out that the proposed IVO instrumentation would be more optimized for Io studies than the proposed JEO instrumentation would be for Io. However, this may not remain the case. The proposed instrumentation for JEO is a strawman to show capabilities and allow conceptual design of the orbiter. The actual instruments will be selected from proposals submitted by scientists in several years time. It is very possible that the winning instruments will be tuned to do better at Io than the current strawman payload would.
Two missions to the Jovian system are on the official list for the next New Frontiers mission ($650M). One is an Io observer and the other a Ganymede observer. The selection of JEO and possibly JGO would seem to make the selection of the Ganymede observer unlikely in my opinion. JGO is the Ganymede observer done right. The Io observer faces hurdles in terms of being selected, too. As Jason points out, there are still valid reasons to fly IVO. The science it would return over what JEO will and may return has to be better (and at lower risk) than the science from all other proposed missions. That may not be possible. I would love to see IVO fly, but I have strong doubts that it will. (Note: IVO is a Discovery mission ($450M) and not a New Frontiers mission. However, I think this reasoning still applies.)
As my final thoughts, I’ll speculate on what may be a crowded place the Jovian system could be in the 2020s. This year (2009) is the year of the moon with Chinese, Japanese, Indian missions there now. ESA just finished a lunar mission and NASA will launch its soon (with more to come). The 2020s could be the decade of Jupiter. NASA and ESA may have orbiters exploring the moons and observing Jupiter itself. The Japanese space agency, JAXA, is considering an orbiter to explore the Jovian magnetosphere. Russia is considering a lander for Europa. Other nations likely will have the capability to send missions to Jupiter. What might those craft do? Additional craft to explore the magnetosphere would be useful. A craft in polar orbit around Jupiter could study the polar regions of Jupiter, keep an eye on Io, and explore another corner of the magnetosphere.
Unless new news comes out about JEO, I’ll take a break from this topic for a bit. In the next few weeks, the NASA FY10 budget will be released and will show the new administration’s priorities for planetary exploration. There will be meetings of NASA’s scientific advisory boards for Venus where a Flagship mission will be proposed, the Outer Planets where we may learn more about the issues that led the selection of Europa Jupiter over Titan Saturn, and Mars where re planning the exploration roadmap for the next decade will begin. I also want to complete the discussion of concepts for missions for the next New Frontiers mission selection.

c)How EJSM affects the Io Volcano Observer
With a mission now planned for the Jupiter system in the 2020s, how will the Io Volcano Observer proposal be affected? Would a dedicated Io mission even be necessary?
The Io Volcano Observer and the Jupiter Europa Orbiter would conduct complimentary science. Both spacecraft have high-resolution cameras capable to studying Io’s surface in fine detail during flybys as well as monitoring Io’s global volcanic activity from a distance. Both can conduct mass spectroscopy of Io’s atmosphere and plumes as well as observe Io’s thermal inertia. The Jupiter Europa Orbiter would be capable of acquiring observations not currently in IVO’s baseline payload such as near-infrared spectroscopy, ground-penetrating radar, laser altimetry, and particle and plasma analysis. So seemingly, the Io Volcano Observer would not be necessary. Not so fast.
The Jupiter Europa Orbiter’s instruments are designed to study Europa, with bandpasses of the various instruments and their functionality driven by that requirement. Studying the other bodies in the Jupiter system, while a level 1 science requirement, really is just gravy for the mission. JEO’s unique instrumentation, such as the Ground-penetrating radar, can answer quite a few questions that IVO can’t. However, the design of the payload for IVO has been defined to specifically answer questions at Io. For example, the camera on IVO would be capable of observing volcanic activity with multiple filters with less than 0.1 seconds between color frames. This allows fairly accurate measurement of the lava temperatures at Io’s volcanoes. This can constrain the amount of partial melting in the mantle needed to support the eruption temperature observed. The band passes on the Thermal Mapper, rather than being selected to search for warm spots on an icy world, will be selected to explore different volcanic processes on Io of different ages as well as looking at the silicate composition of these flows.
Also, don’t forget that IVO will perform at least seven Io flybys during its 1.5-year primary mission (starting in early 2021), three more than the encounters planned for JEO. In addition, IVO has enough margin in its radiation shield to support seven more encounters, which could be spaced out by as much one year apart to help study the long-term life time of IVO’s power source, the two Advanced Sterling Radioisotope Generators (ASRGs). This extended mission could help fill the gap between IVO’s primary mission which ends in late 2022 and JEO’s arrival in late 2025. This provides the potential for spacecraft monitoring of Io covering almost eight years, similar to Galileo’s time at Jupiter.
While the Jupiter Europa Orbiter will perform quite a bit of science at Io, since the instruments are not optimized for Io science, there is still a need for a dedicated mission like Io Volcano Observer. Potentially JEO could allow IVO to trim some costs by reducing some of the redundancy, like the magnetometer instrument. However, the priority for an Io mission may go down in comparison to other potential Discovery-class missions with the EJSM arrive only a five years later than IVO.

The world’s most powerful operational rocket, packing 8.8 million pounds of thrust at launch, launched on its inaugural flight from Florida’s Kennedy Space Center on Wednesday, November 16, at 1:47 a.m. ET
The 98-meter-tall SLS rocket will launch the unmanned Orion spacecraft on the Artemis I mission to the moon, where it will fly by the moon at a distance of 40,000 miles from its far side and 62 miles from its surface, which is the closest any human-rated spacecraft has ever come to the moon’s surface. Orion will splashdown in the Pacific Ocean off the coast of California on December 11, bringing to a close the mission, which is testing technologies for potential crewed lunar missions.
The Artemis Real-time Orbit Website offered by NASA allows you to track the spacecraft’s movement (AROW). The website provides information on the location of the Orion in detail as well as its separation from the moon and Earth. After a number of recent launch delays brought on by technical difficulties and severe weather systems, NASA officials will be relieved to see the SLS rocket finally ascend.
A successful Artemis I mission will open the door for Artemis II, which would follow the same course around the moon but with astronauts aboard the Orion spacecraft. Following that, the much awaited Artemis III mission will attempt to land an astronaut on the moon for the first time since the final Apollo mission in 1972, putting the first woman and first person of color there.
We are going.

The US Air Force has conducted the first test flight of a new long-range stealth bomber, one of six operational prototypes scheduled to be produced by US arms giant Northrop Grumman.
The plane, dubbed the B-21 Raider, was seen in the skies of Northrop’s Palmdale, California, research facility on Friday afternoon, with footage of the flight captured by aviation photographer Matt Hartman.
The Air Force later confirmed the flight and called for prosecution “A critical first step in the test campaign managed by the Air Force Test Center and the 412th Test Wing’s B-21 Joint Test Force.” The new plane will “Provide penetrable, long-range offensive capabilities to deter aggression and strategic attacks against the United States, its allies, and partners.” Air Force spokeswoman Anne Stefanik added.
As part of the Pentagon’s long-range attack bomber program launched in 2011, the B-21 is expected to enter service sometime in 2027, according to Lt. Gen. James C. Dawkins, deputy chief of staff for strategic deterrence and nuclear integration. Officials hope the plane will replace several aging bombers over the coming decades, including the B-1 Lancer, B-52 Stratofortress, and B-2 Spirit.
Northrop Grumman, which also designed the B-2, acknowledged the test flight Friday in a statement, saying it would be. “Validate our digital models” And signs “Another step closer to reaching operational capability.”
During a House committee hearing last year, then-Pentagon Deputy Chief of Staff for Plans and Programs, Lt. Gen. David S. Nahum, the Army may seek to acquire up to 145 B-21s once the program is complete.
The new stealth aircraft faced setbacks during its development with the Air Force delay Her first trip was last year for unspecified reasons, citing the need for protection “Sensitive program information from adversary exploits.”

After the start of the Korean War in 1950, test teams moved to the combat theater for testing in actual combat.

Kate uses observations from the FAAM BAe146 research aircraft to study aerosols and their interaction with radiation, clouds and chemistry.
Areas of expertise
- Aircraft scientific instrumentation
- Observational data analysis
- Cloud and aerosol physics measurements
- Weather forecasting
- Field campaign logistics
Kate is a senior scientist using observations from the FAAM research aircraft to understand the impact of aerosols on atmospheric radiation. In situ and remote sensing measurements made from the aircraft are compared to radiative transfer models to assess the model's performance and achieve an improved understanding of aerosols and their radiative impacts.
Currently, Kate is heavily involved in a project to build a new state-of-the-art spectroscopic instrument to characterise aerosol optical properties. The instrument - called EXSCALABAR - is designed to fly on the FAAM BAe146 research aircraft with first scientific field measurements anticipated in 2016. EXSCALABAR aims to fulfil the future Met Office observational needs for aerosol absorption and humidified extinction, coupled with particle sizing, ultimately intending to improve weather, climate and air quality models. The Cavity Ring-Down and Photo-Acoustic Spectroscopic (CRDS and PAS) techniques at the heart of the instrument have been used successfully for airborne aerosol research by NOAA Earth Systems Research Laboratory. EXSCALABAR builds upon the design of the NOAA instrument and will continue to share commonality in some optical, electronic and flow elements. Measurements of aerosol optical properties made using EXSCALABAR will benefit from lower uncertainties and greater sensitivity and time resolution than has been possible to date when using the FAAM aircraft.
Kate's contributions to the project include designing and building of the flow system, procuring a suitable instrument to measure aerosol size distribution and characterising it, setting up equipment to generate aerosols to test the instruments and establishing the instrument ground and flight test program required to fully characterise EXSCALABAR.
Kate graduated from St Andrews University in 1998 with a degree in Chemistry. From there, she moved to Cambridge to study for a PhD in Atmospheric Chemistry. Her project was to build and use a novel dew/frost-point hygrometer intended for tropospheric and lower stratospheric measurements of water vapour from a balloon borne platform.
Subsequently, Kate joined the Met Office to train as a weather forecaster in 2003. During the next couple of years, she worked mostly at Met Office Aberdeen, forecasting for a wide variety of customers extending from the offshore oil industry and Maritime and Coastguard Agency to BBC Scotland and road gritters. There were also brief spells at RAF Lossiemouth and with the Army in Gütersloh forecasting for military aviation customers.
In 2006, Kate moved from Aberdeen to Cranfield to become more involved with weather research. As part of the team operating theFAAM research aircraft, Kate was responsible for the cloud physics and some aerosol instrumentation used on the aircraft. In addition to ensuring the right instruments were available and in good working order for the projects, this job frequently required Kate to get assess instrument performance and make rectification work as necessary. Kate moved to the Aerosol Research Group in 2009 where she is using her experience working with the FAAM aircraft and instrumentation to understand data from a variety of projects. | aerospace |

Boeing Commercial Airplanes chief Jim Albaugh said he's becoming "very confident" about the 787, as the company reported healthy first-quarter profits Wednesday.
Seattle Times aerospace reporter
Boeing executives maintained a positive outlook for the year ahead as they reported healthy first-quarter profits Wednesday.
Despite the clouds of volcanic ash lingering over parts of Europe, they project a continued global economic recovery that will buoy the aviation business.
In a teleconference with analysts and news media, CEO Jim McNerney expressed renewed confidence in the schedule for both Boeing planes in flight testing: the 787 Dreamliner and the 747-8 jumbo jet.
Jim Albaugh, head of the commercial-airplanes division, also spoke glowingly about the 787's performance in a separate interview with The Seattle Times.
He said flight-test data show the 787 looks increasingly like the market game-changer Boeing projected it would be and will meet all the performance targets promised the airlines.
"Based on what I see from a performance standpoint, from an aerodynamic standpoint, from an engine standpoint, from a weight and range standpoint, I think we are going to be OK," Albaugh said. "The performance of the airplane very closely meets the models we had in place ... We're starting to feel very confident."
During the earnings call, McNerney said a larger version of the 787 that Boeing has studied, the 787-10, looks less likely.
He said improvements to the second version of the Dreamliner, the 787-9, as well as possible design changes to Boeing's larger 777, may cover the requirements of airlines in the large twin-jet category, without the need for a 787-10.
Potential changes to the 777 include new carbon-fiber structure, he said — presumably new composite wings.
Albaugh said later that McNerney was "commenting on some preliminary data that was shown to him," and no firm decision on the 787-10 has been made.
The Federal Aviation Administration (FAA) gave the 787 expanded "type inspection authorization" Tuesday, which means FAA inspectors will join Boeing engineers aboard the test airplanes to monitor progress and collect data.
McNerney said that although this key milestone was reached about a month later than originally planned, the flight-test schedule still has four to six weeks of buffer to cover unexpected contingencies.
Albaugh conceded the disruption in Europe caused by the Eyjafjallajökull volcano will put financial pressure on some key customers such as British Airways.
"We all know the financial position of many of the airlines is fragile," said Albaugh.
But the dangers from volcanic ash are real, he said.
"We have data on what happens to the engines when you get the silica-based ash into the hot side of the turbine. It turns to glass. It can impact the cooling. It can impact the shape of the blades. It's something we take very seriously," Albaugh said.
As the chaos in Europe appears to be lifting, Albaugh said he doesn't anticipate any impact on jet deliveries from Boeing's factories.
Asked about the Air Force refueling-tanker competition, a day after Airbus parent EADS re-entered the race for the $40 billion contract and stated its goal to beat Boeing on price, Albaugh took a dig at Airbus for taking subsidies to fund airplane development.
"We do have to make money with our programs," he said, "We develop our airplanes the old-fashioned way. We pay for them ourselves.
"The good news is we've got another 60 days now to try to drive the cost of this airplane down," Albaugh added. "I think we'll be very, very competitive."
After recently announcing production-rate hikes in Everett starting next year, Boeing will decide by June whether to increase production of the Renton-built 737 as the global economy strengthens.
"The pressure is upward on the 737 line," Albaugh said.
He said a glitch in current production programs stemming from problems with a seat supplier is under control.
Japan's largest aircraft-seat supplier, Koito Industries, earlier this year admitted it had falsified data on fire and impact protection in its products, resulting in certification and delivery delays.
Albaugh said the problem is being "managed very aggressively" by Boeing, which is doing "workarounds" and looking for alternative suppliers.
"We're working with (Koito) because they have seats we need," said Albaugh. "We also want to make sure we don't find ourselves overdependent on one supplier."
Albaugh said it's possible the decision between a 787-10 and a revamped 777 will be made this year. Also, a decision on whether or not to develop a new engine for the 737 will certainly be made by year-end.
"We've got to put two new airplanes into service and we've got to make some decisions on the future of Boeing Commercial this year," Albaugh said. "This is a pretty big year for us."
Boeing said Wednesday it had booked profit of $519 million, or 70 cents a share, on first-quarter revenue of $15.2 billion. That was down 14.9 percent from a year earlier, largely because of a previously announced, one-time $150 million accounting charge due to the recently passed health-care legislation.
Analysts surveyed by Thomson Reuters expected a profit of about 63 cents a share, according to The Associated Press.
Profit margins were just over 9 percent for the quarter in the commercial-jet division — flat from a year earlier after accounting for a one-time charge in 2009.
Margins for the full year are expected to be lower as Boeing begins delivering the initial, low-margin 787 and 747-8 jets, as well as incurring the costs of fleet support and training as airlines introduce the two new airplanes.
The quarter's commercial-airplane deliveries were down 13 jets compared with a year earlier, but Albaugh said that was largely a result of pulling some planned January jet deliveries forward so that they were booked at the end of 2009.
Boeing ended the quarter with $10.4 billion of cash and liquid securities, $860 million less than at Dec. 31. A major reason for the drop is the buildup of 787 and 747-8 inventory.
The company projects spending about $4 billion on R&D this year, the bulk of it in the commercial-jet unit. It also plans $1.9 billion in capital expenditures, including $700 million for construction of the new 787 assembly line in Charleston, S.C.
Boeing shares closed Wednesday up $2.75, or 3.9 percent, at $74.16.

has anyone taken a roadworthy motor vehicle and made it fly. (See-The Mitzar) This new accomplishment was shown Thursday November 16, 2006,
the work of a nine man team from the History Channel's television show "Monster Garage".
The show was the brain child of Jesse James (a master mechanic - not the desperado). He and his crew had five days
to construct a flying car from the salvaged parts of a hurricane-damaged Cessna, along with the shell and selected components from
a $90,000.00 Panoz Esperante, which is an exotic aluminum and carbon-fiber sports car built in Atlanta.
In the Long Beach, California shop of the "Monster Garage" this project was ambitious even by their somewhat audacious standards.
Among their other accomplishments, this is the shop that had turned a Mustang into a 50-mph lawnmower, and a school bus into a party boat.
Like all Monster Garage teams, this one was a patchwork of people from different backgrounds: three engineers on loan
from Cessna, a couple of guys from Atlanta Air Salvage, two mechanics from Panoz, a couple of aircraft enthusiasts and
fabricators, and a fellow who's been working on his own flying car project for years.
There was a substantial pile of leftover Esperante parts in the corner of the shop, as nearly a thousand pounds
of car had been removed to lighten it. Added to the auto were items salvaged from the Cessna - wings at a span of 40 feet, spars,
tail feathers, a carbon-fiber propeller, and a Lycoming O-320, which is a 200-plus-pound, four-cylinder aircraft engine. Remember,
there's still a Ford 4.6-liter, 32-valve DOHC V8 under the hood.
The Final Result - - Jesse James and the crew from "Monster Garage" actually got the Panoz Esperante to fly. James took the
Esperante aloft for around five seconds, reaching an altitude of two feet, and a total flight distance of 121 feet. There was
no damage to the car, and no there were no injuries to the flight crew.
Not bad fellows. Although it is not official, your achievement is believed to be better than the Glen Curtiss' flight in the Autoplane in
1919. We hear your TV ratings for the show were good too. | aerospace |

The company is making the change because it is putting more of its money and time into “developing products, services, and technology.”
Some of the jobs will be given to Tata Consulting Services, which is part of one of India’s largest business groups.
In the past few years, Boeing has had to deal with a number of problems, such as the grounding of its 737 Max after two fatal crashes.
“We have told our teams and will continue to tell them in a clear way that we expect some corporate support functions to have less staff,” the company told the BBC.
“As always, we’ll help affected teammates get back on their feet by giving them help and resources,” it said.
About a third of the jobs will be given to Bangalore-based Tata Consulting Services (also known as Bengaluru).
But Boeing also said it will keep hiring more people “with a focus on engineering and manufacturing.”
The company said it plans to hire another 10,000 people this year on top of the 15,000 people it hired in 2022.
After two deadly accidents involving its 737 Max passenger jet, the aviation giant has been trying to turn things around.
On October 29, 2018, 13 minutes after taking off from Jakarta’s Soekarno-Hatta International Airport, Lion Air Flight 610 crashed into the Java Sea. All 189 people on board were killed.
Less than five (5) months later, Ethiopian Airlines Flight 302, a Boeing 737 Max that was going to Kenya, crashed just six minutes after taking off from Addis Ababa, the capital of Ethiopia. All of the 157 people on board died.
Later, it was found that both accidents were caused by mistakes in the way the planes were made, especially in the way they used a piece of software called the “Maneuvering Characteristics Augmentation System” (MCAS).
The system was made to help pilots who had flown earlier versions of the 737, so they wouldn’t have to pay for extra training to fly the new model.
But sensor failures caused it to stop working, and in both cases, the plane went into a fatal dive that the pilots could not stop.
The 737 Max plane can now fly again in most countries around the world. This is because the plane was fixed, and the pilots were trained. | aerospace |

One of them will come close to Earth this week. Here’s everything you need to know.
Massive asteroids coming towards Earth
According to data from the Center for Near-Earth Object Studies (CNEOS), a NASA organization, 2021 SM3, an asteroid discovered last month is passing towards Earth on Friday. The asteroid has a diameter of 525 feet and is larger than the Great Pyramid of Giza which measures 482 feet. While it is not heading for the planet, its impact will only “cause local damage to the impact area.” However, the asteroid will be about 3.6 million miles from Earth.
According to NASA, 2021 SM3 is a near-Earth object (NEO). NEOs are any object that comes within 120 million miles of our planet. According to NASA, NEOs “are comets and asteroids that have been nudged by the gravitational attraction of nearby planets into orbits that allow them to enter the Earth’s neighborhood.”
More on the other NEOs coming close to Earth
2021 SM3 is not the only asteroid that will soon pass by Earth. Several others larger than the 2021 SM3 will be in Earth’s proximity before the end of November. Out of them, 1996 VB3 will be the closest to us. The 754 feet wide NEO will be just 2.1 million miles away from us on October 20.
Additionally, 2004 UE with a diameter of 1,246 feet, slightly shorter than the Empire State Building is the largest in the group. It is expected to be 2.6 million miles away on November 13. However, it is not the biggest one this year. 2001 FO32, a NEO estimated to be 3,000 wide flew past 1.2 million miles from Earth. | aerospace |

Today’s guest blogger is Stewart Bailey, curator of the Evergreen Aviation and Space Museum, one we have visited many times. The central piece in this museum’s collection is the one-of-a-kind so-called Spruce Goose, built by Howard Hughes. Before he became the curator at the aviation museum in MicMinnville, Oregon, Stewart Bailey was the education director at the Air Zoo in Kalamazoo, Michigan, another great museum we’ve visited. We’ve written about the Spruce Goose before at Lofty Ambitions (CLICK HERE) and welcome the insider’s take on this aviation endeavor.
WINGS OVER WATER
This year, as the U.S. Navy celebrates the 100th Anniversary of Naval Aviation, it is interesting to reflect on how the aircraft, the ship, and the technologies they embody, have shaped our world. When one looks at the centuries preceding the twentieth, the major powers that controlled the world were those that controlled the sea. From the Phoenicians to the Dutch, the Spanish and the British, the growth of commerce, the spread of knowledge, and the fruits of empire belonged to those that controlled the world’s oceans. But with the rise of the airplane, that all changed.
In World War II, the struggle between the ship and the aircraft was at its peak, and many of the world’s fiercest battles took place between these technological antagonists. Even forty years after the Wrights took to the air, there was still a question of whether or not aircraft would replace the ship (or the sub-surface ship) as the dominant factor in controlling the seas. Most notably in the Atlantic, German submarines had a stranglehold on the Allies’ ability to move men and supplies, making prospects of an American invasion of Europe somewhat dicey.
It was at this point that industrialist Henry J. Kaiser came up with a game-changing proposal: if German U-Boats are sinking so many ships at sea, why not fly over them? Kaiser proposed a fleet of “flying cargo ships,” moving vast quantities of men and material over the ocean, non-stop to Europe and Africa. Also, being a shrewd businessman, he surely saw the impact that such an idea would have on world commerce after the war was over. However, Kaiser was not an aircraft builder, so he turned to Howard Hughes to make this concept a reality. Together, they received a government contract to build three aircraft within two years that could carry up to 750 troops or two Sherman tanks and would bring the might of America to the old world’s door. But there was one caveat: these aircraft had to be made of non-strategic materials such as wood.
The result was the largest aircraft in the world. It was to have a wingspan longer a football field and be powered by eight of the largest piston aircraft engines ever built. At that size, there was no runway in the world that could handle it, so it had to be a seaplane so that it could use miles of water to take off and land. It would push the limits of existing materials and aeronautical technology to leapfrog over the threats presented by the submarine.
But there were problems. By 1944, as the two-year time frame closed in, Kaiser grew frustrated with Hughes’s perfectionist nature that delayed the aircraft; by then, it had only just begun construction. He withdrew from the project in mid-1944, leaving Hughes to go it alone with his efforts to create a flying freighter.
The aircraft that Hughes shaped was both elegant and technologically advanced. Hughes oversaw every aspect of design and was particularly concerned with the control systems, since he personally test-flew all of his designs. He wanted it to be capable of being flown by one pilot, and he insisted on the control layout being to his personal taste. An outcome of this was the hydraulically assisted controls that allowed the pilot to move ailerons, elevators, and a rudder that were the size of whole wings on some aircraft. Additionally, Hughes beat the challenge of making the plane from wood, utilizing a process called Duramold in which thin layers of birch were bonded together with resin glue and shaped under extreme pressure and temperature. The resulting material, for its weight, was stronger than wood.
Despite numerous setbacks and delays, the Hughes H-4 Hercules, (derisively called the Spruce Goose by the media), did take to the air on November 2, 1947. Its single flight became a culmination of Hughes’s vision for the flying cargo ship. But by that point, the very reason for which it existed had vanished. The Second World War had unquestionably proven that the aircraft had replaced the sea-going vessels as the new measure of global power projection.
So, was the so-called Spruce Goose a waste of time and money? No, not at all. By its very creation, it helped to pioneer technologies like the hydraulically assisted controls that make today’s transoceanic airline flights routine. It helped ensure that the aircraft would make global commerce possible on a scale beyond the imagination of ancient sea-faring nations. And it proved that, while not every technological effort is a success, there is no success without effort.
Today, the Hughes H-4 Hercules rests in the Evergreen Aviation & Space Museum, a reminder of a time when the struggle for control of the seas—and of the world itself—hung in the balance. | aerospace |

The flyby spacecraft is about the size of a Volkswagen Bug.
The impactor is about 3 X 3 feet, about the size of a desk and weighs 370 kg (820 lbs).
The entire combined spacecraft weighs about 1 ton.
The impact did not knock the comet out of its orbit because the force of the collision between the impactor and the comet was like a moving truck hitting a pebble. It did not affect the speed or direction of the comet to any noticeable degree.
The closing speed of the comet to the impactor is 10 times faster than a speeding bullet.
The crater is expected to be up to the length of a football stadium and several stories deep.
The ejecta curtain coming out of the crater might look like what you get when you throw a rock into a can of paint (funnel shaped spray).
If you view the impact of Comet Tempel 1 from Earth with a large telescope it might look like a bright flash followed by a glowing stream. It would take a couple of minutes after the flash for the "stream" to separate from the center of the comet.
It takes 7 1/2 minutes for the flyby spacecraft signal to reach Earth. Once the mission is within its last hour, there is no time for the team on Earth to communicate effectively with the twin spacecraft. That is the reason auto navigation systems are being built into the flight plan.
The communication time between the flyby spacecraft and the impactor takes less than one second.
Prior to impact, the flyby spacecraft moves away from the comet to a safe location for observation of the event. | aerospace |

Vancouver, British Columbia
2442 Aircraft Control & Warning & Unit (Reserve) Vancouver was formed on 1 April 1950 to train personnel in radar operations for the new radar stations then under construction as well as to train these same personnel in all aspects of aircraft control and warning. 2442 AC&WU reported to No. 5 Air Division at Vancouver.
On 1 November 1951, 2442 AC&WU was re-designated as 2442 Aircraft Control & Warning Unit (Auxiliary), and on 1 December 1953, the unit became a squadron.
Some of the Regular AC&W Squadrons that unit personnel were deployed and employed at included Holberg, Baldy Highes, Kamloops and Blaine Washington. The unit personnel worked hand in hand with their Regular counterparts from both the RCAF and USAF. Narrative reports on the Pinetree Line web site confirm that 2442 AC&W Squadron was active at Kamloops Air Station, Kamloops BC in 1960 and RCAF Station Lac St. Denis in 1952.
2442 AC&W Squadron was yet another victim of the SAGE system. Consequently, on 31 March 1961, the Squadron was disbanded.

Philippines: Smoke fills sky after C-130 aircraft crashes
Forty-five people have been killed including civilians on the ground after a military plane crashed and exploded into flames in the southern Philippines.
A number of soldiers jumped out of the Lockheed C-130 transport aircraft before it slammed into the ground with 96 people on board.
The Department of National Defence said 45 people had been killed, including three civilians on the ground, while 53 were injured, including four civilians. Five military personnel were still missing.
The Air Force plane, carrying troops bound for counter-insurgency operations, had attempted to land at an airport on Jolo island, but overshot the runway without touching down.
It failed to regain enough power and height and crashed at nearby Patikul in the country’s worst military air disaster in nearly 30 years.
Pictures from the horrifying scene on Sunday morning showed bright orange flames and thick grey smoke pouring from the wreckage of the aircraft among trees.
A large column of black smoke rose into the blue sky.
Dramatic video footage at the scene showed the plumes of smoke rising as commotion and coughing could be heard in the background.
“A number of soldiers were seen jumping out of the aircraft before it hit the ground, sparing them from the explosion caused by the crash,” the Joint Task Force Sulu said in a statement.
It was not immediately clear how many jumped or whether they had survived.
Military chief Cirilito Sobejana said the plane had “missed the runway trying to regain power”.
The Defence Minister earlier told Reuters the plane had been carrying 92 people, including three pilots and five other crew members.
Officials have since confirmed 96 people were on board.
A military spokesman, Colonel Edgard Arevalo, said there was no indication of any attack on the plane, but that a crash investigation had not begun and efforts were currently focused on rescue and treatment.
The military command said the soldiers aboard had the rank of private and were being deployed to their battalions.
The army in the sprawling Philippine archipelago has been fighting a long war against Islamist militants from Abu Sayyaf and other factions.
Sobejana said the plane had crashed a few kilometres from Jolo airport at 11: 30 a.m (0330 GMT) after flying about 300 miles from Laguindingan.
“We are currently attending to the survivors who were immediately brought to the 11th Infantry Division station hospital in Busbus, Jolo, Sulu,” he said.
Helicopters were deployed to transport the injured to hospital.
Al Jazeera said the C-130 is one of the newly acquired planes by the Philippines Air Force.
The area where the tragic crash happened was said to be ‘home to one of the huge bases of the Philippines military’.
BOGS MUHAJIRAN via REUTERS)
Jolo airport has a 1,200-metre runway that usually takes civilian turboprop flights though occasionally some military flights, according to a Civil Aviation Authority of the Philippines spokesperson.
Jolo island, which is part of the Sulu archipelago, is about 950 km (600 miles) south of the capital, Manila.
The Lockheed C-130H Hercules aircraft, registration 5125, had only arrived in the Philippines recently.
It was one of two aircraft granted by the US government through the Defense Security Cooperation Agency, according to a government website announcement in January.
It quoted an air force spokesman as saying the aircraft would provide enhanced capability for heavy airlift missions.
The website C-130.net said the plane that crashed had first flown in 1988.
The model is a workhorse for armed forces around the world.
A Philippines Air Force C-130 crash in 1993 killed 30 people.
A 2008 crash of the civilian variant of the Lockheed plane flown by the Philippines Air Force killed 11 people, the Aviation Safety Network says.
The country’s worst plane crash was that of an Air Philippines Boeing 737 in 2000, which killed 131 people.
The incident comes after it was reported a private plane crashed in Haiti killing all six people on board including two American missionaries.
The plane went down on Friday evening, on a short flight from a Port-au-Prince airport to the southern coastal city of Jacmel, the National Civil Aviation Office reportedly said.
The cause of the disaster was not immediately known but it reported that the plane crashed into a mountain. | aerospace |

I was pleased with the way it flew, but like so many of us, Iwanted to experiment some more once I nailed down the step on thebottom. When I placed it on the top I found out that it produced higherlift than the one on the bottom. It would climb higher and travel alonger distance. Later tests at Notre Dame confirmed that the step onthe top was able to generate higher lift over drag. I then playedaround with placing the elevators on the upper surface just in front ofthe rudder. After many different experiments and many different flightsI had perfected The Condor, which would be the plane I would use tochallenge the Wright Brothers distance record. In spite of very strongwinds coming in off Cape Hatteras, I was successfully able tooutdistance the distance record for the first manned flight of 122feet. I did this in 1985 down in Kill Devil Hills, NC right on the spotwhere the Wright Brothers first flew. My distance was 401 feet, fourinches. On the fourth flight that day of the Wright Brothers historicflight they traveled quite a bit further, so I was lucky that theirfirst flight was just 122 feet.Here is the data from the wind tunnel at Notre Dame. It would have beena lot higher if we had a rounded leading edge and a little camber. Butwe were interested in seeing exactly what the step produced by itself.Later, everyone would follow this configuration out the window and getpoor results. This was our big mistake. But we also knew at that timethat the step worked in different configurations and we couldn't patentthem all. All we wanted was to patent a step in the hopes that it wouldproduce stall resistance to other airfoils. All the experts trashedthis idea as too high in drag, yet the KFm4, with a step on the top anda step on the bottom, increases the speed of the wing. If the drag wasso high, how could this be?All in all, it has been a wonderful adventure and I feel very gratefuland lucky for it. I have come in contact with many truly wonderfulpeople in the RC community. From my perspective, the world could takesome lessons from the RC people on how to work together, how to openlyshare information and knowledge freely and produce an environment ofcreativity and experimentation. This way everyone benefits and thelearning curve climbs way up for everyone.The gentleman who conducted these tests at Notre Dame was ProfessorJohn D. Nicolaides, the first head of NASA. | aerospace |

When you oversee a $4.5 billion program that launches teams of astronauts into space using some of the most complicated vehicles on the planet, you have few peers.
So, whom do you turn to for advice on working your safety program? Who offers a model for the safety, quality assurance, and program management tools that you need to develop to meet current and foreseeable challenges? Whose lessons-learned can you learn from? For the National Aeronautics and Space Administration (NASA), which was looking to answer these questions in 2002, the choice was clear: The U.S. Navy’s Submarine Force.
At first glance, this choice might seem counter-intuitive. NASA’s Space Shuttle Program (SSP) is focused on conducting missions in space. SSP engineers live in
a world dominated by aeronautics and zero-gravity, wind shear and superheated gasses, heat-resistant tiles and solid rocket boosters. Conversely, submarines primarily operate below the surface of the world’s oceans. There, hydrodynamics, navigational charts, ballast tanks, sonar and weapons systems, and nuclear reactors are far more important.
But, having served as the Secretary of the Navy from 1992 to 1993, the former NASA Administrator, Sean O’Keefe, knew something that most people looking in from the outside do not. While major differences inevitably exist between the submarine and human space-flight programs, there are also many, many similarities. For example, both NASA and Submarine Force programs are of high national importance, place great emphasis on human safety, and operate in hostile environments. Accordingly, both programs incorporate high-levels of system and platform redundancy. Operational integrity must be maintained despite outside pressures, and scheduling, budgetary, and political influences cannot be allowed to undermine safety considerations. Integrating modular components from multiple vendors presents significant design and safety issues. And the list goes on.
A Partnership Established
Given his unique perspective, Mr. O’Keefe was also keenly aware of the Submarine Force’s history of overcoming technical, managerial, and budgetary obstacles while maintaining a culture of safety. He mentions this as a main reason for turning to the Submarine Force in a June 13, 2002, letter to Secretary of the Navy Gordon R. England.
“Today, NASA’s Space Shuttle and International Space Station program managers are facing many challenges, including maintaining product quality and safety, accomplishing required performance and safety upgrades, and maintaining a skilled and motivated workforce in the face of budget and schedule pressures,” wrote O’Keefe. “These issues are well understood by the Navy’s nuclear submarine program managers who faced similar challenges during a downturn in production in the early 1990s... I believe that NASA can learn much from the Navy’s experience.”
In August of 2002, spurred by Mr. O’Keefe’s letter, NASA and the Naval Sea Systems Command (NAVSEA) embarked on a two-way exploration of safety and management issues. The group conducting the effort, known as the NASA/Navy Benchmarking Exchange (NNBE), was tasked with studying both organizations’ safety and mission assurance paradigms, risk management and work processes, organizational structures, tools, certification processes, and verification and compliance processes.
The NNBE is made up of senior representatives from NASA’s Office of Safety and Mission Assurance and NAVSEA’s 07Q Submarine Safety and Quality Assurance Division (SUBSAFE). Other NASA and Navy programs also played important roles in the effort, and continue to do so.
A report on the NNBE efforts, issued on Dec. 20, 2002, identifies elements of the SUBSAFE program that could serve as a model for NASA safety and mission assurance initiatives and points to lessons learned by SUBSAFE that can be applied to NASA efforts. Another report, released on Oct. 22, 2004, details more recent NNBE activities and NNBE Software Subgroup findings.
Subsequent reports are expected but not yet available. Topics will include a review of software safety and mission assurance for the International Space Station (ISS) program; analysis based on observation of a SUBSAFE Certification Audit; and critical evaluation of risk management, material control, work and configuration management, personnel management, and design tools and techniques.
After a review of the Navy’s SUBSAFE program, as reported in NNBE’s first
public report, the group identified several potential opportunities for NASA to benefit from SUBSAFE successes. These were divided into three groups: Requirements and Compliance, Lessons-Learned and Knowledge Retention, and Process Improvement.
The first group of opportunities took aim at a difference between NAVSEA’s and NASA’s concepts of operations. NAVSEA management philosophy is rooted in “clear and realistic requirements definition... and independent verification of compliance,” noted NNBE. Waivers are rarely accepted for deviations from safety-related baseline requirements, and when they are, they sometimes impose limitations on the submarine until the deviations are remedied. NASA does allow waivers to safety-related baselines and employs other management techniques to mitigate the risks involved. | aerospace |

They have opened up new possibilities for industries such as agriculture, construction, mining, and surveying, allowing professionals to easily capture high-resolution aerial images and create detailed maps and 3D models of their sites. However, when it comes to creating accurate and detailed maps, one important consideration is the drone map Ground Sampling Distance (GSD).
What is GSD?
Ground Sampling Distance (GSD) is the distance between two consecutive pixels in an aerial image, measured on the ground. It is usually expressed in centimeters per pixel (cm/pixel) or meters per pixel (m/pixel). GSD is an important parameter for creating accurate and high-resolution maps, as it determines the level of detail that can be captured in an image. The lower the GSD, the higher the resolution of the image, and the more detailed the resulting map will be.
Why is GSD important in drone mapping?
GSD is a critical factor in drone mapping, as it directly affects the accuracy and quality of the final output. A lower GSD means that more pixels are captured per unit area, resulting in a higher resolution image and more accurate data. For example, if you are mapping a site with a GSD of 2 cm/pixel, you can see objects as small as 2 cm on the ground. This level of detail is essential in industries such as construction and mining, where accurate measurements of features such as stockpiles and excavations are crucial.
What impacts GSD?
Factors such as the drone camera focal length, the sensor pixel size, and the altitude of the camera above the ground all impact GSD. The camera sensor of a consumer or prosumer drone typically cannot achieve the same GSD as an industrial drone and professional camera payload without flying much lower to the ground and taking many times the photos.
In conclusion, GSD is a critical factor in drone mapping, as it determines the level of detail that can be captured in an image. A lower GSD means that more pixels are captured per unit area, resulting in a higher resolution image and more accurate data.

Though the iconic aircraft won’t be leaving without considerable fanfare, as Qantas responds to demand with announcement of several “farewell jumbo joy flights” for Australians.
Qantas will be operating three one-hour flights on the aircraft this month, departing from Sydney, Canberra and Brisbane. This will give employees and passengers one final chance to fly on the stalwart aircraft, a legacy imbued with five decades of history-making moments for the national carrier.
“Since the first 747 joined the Qantas fleet in 1971, these aircraft have operated numerous rescue flights to bring Australians home during times of crisis and provided a safe passage for many travellers taking their first international flight to or from Australia”, said Qantas 747 Fleet Captain Owen Weaver. “These three flights will offer the final opportunity to fly on the Qantas 747 before it leaves, with some of our frequent flyers and aviation enthusiasts as fond of the aircraft as we are, having spent thousands of hours onboard over the years.”
The flights will go on sale at midday on Wednesday 8 July on Qantas.com and will operate on Monday 13 July (Sydney), Wednesday 15 July (Brisbane) and Friday 17 July (Canberra). Economy fares cost $400 and a small number of Business Class tickets will be available for $747 with additional extras included.
Seats will be limited to maximise passenger comfort (in line with other previously operated joy flights). All three flights will operate under Qantas’ “Fly Well” measures, ensuring high levels of safety in the face of an ongoing pandemic.
The flights will be operated on a cost-recovery basis and profits will be donated to the HARS Aviation Museum at Albion Park (Wollongong) and the Qantas Founders Museum in Longreach to support their efforts to preserve and promote the 747 legacy for future generations. Both museums have a Qantas 747 on public display.
The final 747-400 in the fleet will depart Sydney at approximately 2pm on 22 July 2020 as flight QF7474.
Bookings can be made through Qantas. | aerospace |

The European Space Agency has identified these orbits as high collision risks. If these orbits remain unattended the debris they release will have detrimental effects on space operations for the next 50 years and onward. The company will create value by reducing the risk exposed to satellite operators from costly avoidance maneuvers and catastrophic impacts. Scout Aerospace is seeking willing partners and staff to capitalize their program and expand their capabilities.
Scout Aerospace LLC seeks to be the number one manufacturer of orbital transfer vehicles and Aldrin cyclers. Named after Buzz Aldrin its conceptual designer, the Aldrin cycler is a type of spacecraft that provides shelter and living quarters for crewed missions between planetary bodies. By shedding all capacity save that needed to travel to the cycler and back, crew transports may be made lighter and cheaper than otherwise required. This kind of transportation has the potential to open new doors of commerce between Earth and future outposts on other worlds. Without reliable, efficient transport such outposts will not be possible. Orbital transfer vehicles (OTVs) are small, short-range vessels capable of servicing existing orbital assets with repairs and refueling. A satellite serviced by an OTV may be, repaired, refueled or repositioned to extend its mission, thereby saving the owner of the satellite a fortune in recapitalization costs.
Scout’s location in Atlanta, Georgia affords it close proximity one of the best aerospace engineering schools in the U.S.A., Georgia Institute of Technology. Aerospace products are Georgia #1 export and Georgia ranks as some of the top States for aerospace manufacturing. Georgia is home to Delta Air Lines, Gulfstream, Viasat, Spaceworks Enterprises, and other aerospace leaders. Today Georgia host three Air Force installations, Moody Air Base AFB, Robins AFB, and Dobbin ARB. Camden County on the coast of Georgia is in the process of establishing a public-private commercial spaceport for vertical launches. All these entities offer a rich field to grow Scout Aerospace. | aerospace |

In both cases the same scenario occurred, namely the nose of the plane repeatedly pointed downwards, forcing the pilots to try to pull up in order to regain control. However, in both cases they were unable to do so and the plane crashed into the ground soon after takeoff killing everyone aboard. Neither plane was old or had any apparent defect. So what caused the crashes?
Unknown to most pilots and not included in the plane’s several hundred page manual, the planes were equipped with a new supposedly safety system, called the Maneuvering Characteristics Augmentation System (MCAS) that is a feature of the Boeing 737 MAX computer flight control system that attempts to provide automatic pitch control of the plane. In other words, if the plane is rising too fast the MCAS is supposed to level it off. But, in fact the system, which was not thoroughly tested before deployment, tends to pitch the plane downwards when it is in level flight. Thus after takeoff in both cases, the planes’s pitch oscillated dangerously leading to the crash.
The official Boeing response to the crashes was that it was a series of events with no one single cause. This is not what the investigations carried out so far reveal. In other words, the MCAS system is considered the direct cause and the fact that the pilots of the MAX had little or no idea what was happening and what MCAS was doing resulted in catastrophe because they were unable to deal with the repeated violent downward tilt of the plane.
The question is not only how Boeing could allow such a potentially dangerous system to be installed on their planes that takes over from the pilots with almost no warning, but how the FAA, the US Federal Aviation Administration, could have approved these planes as airworthy, and why Boeing, knowing they had installed this system, did not immediately ground the MAX fleet after the first Indonesian crash, thus condemning a further 149 passengers to death? These issues will be fought out in court, and several criminal and civil cases are pending. All I can say is it is a shock to all of us who fly and assume that our safety is given first priority. The outcome for Boeing is that their whole MAX fleet is now grounded and they are in a very difficult financial situation. The moral is safety first and always! | aerospace |

On Mars other types of discharges might exist within dust storms. In this commentary we will focus on the historical development of planetary lightning investigations at Jupiter, Saturn, and Venus. Special attention will be devoted to the controversies around the existence of lightning on Venus. Thereby we will highlight the importance of combined optical and radio observations for the epistemological degree of confidence in lightning detection from space as well as for its detailed investigation. Future spacecraft missions to various planets should take this into account. The main future extraterrestrial lightning investigations will be outlined. We also plead for radio observations with a time resolution of the order of microseconds and for more modelling and laboratory work in this field.

Who the hell is buying that? According to the IG, these delays in perfecting Next Generation Spacesuits are a primary reason why NASA may not meet Artemis’s scheduled 2024 landing on the Moon, along with funding shortfalls, and a scheduling delay of approximately 20 months.
Now, there is also a delay until at least November 1st because one of the world’s most narcissistic billionaires, Amazon and Blue Origin’s Jeff Bezos sued NASA in the Court of Claims. At issue is NASA’s award of its human Moonlander contract to Space X, Elon Musk’s company, rather than Blue Origin, Bezos’ company. NASA had originally wanted to fund two Human Landing Systems, but Democrats in Congress did not provide the funding. Space X’s bid was the lowest and it plans to adapt vehicles it already has in the works. Blue Origin lost key technical staff following its failed bid.
Can you imagine what the outcome for the nation would have been, in the middle of the space race, after President John F. Kennedy announced his bold vision for America to “land a man on the Moon and return him safely to earth before the decade was out,” if we had been told that we would not meet that goal because of setbacks in producing a spacesuit or a dispute over the landing system due to funding? Now, NASA is just as much a hostage to the Biden Administration’s insane ideologies, as Americans or our allies stuck on the ground in Kabul.
In 2017, President Donald Trump outlined a new bold mission for NASA when he announced the return of the first woman and next man to the Moon by 2024 through the Artemis Program, the mission named for the twin sister of Apollo. The last time American astronauts were on the Moon was back in 1972. The plan this time was not to return to the Moon for a quick stop and return to earth. We are moving to develop a sustained presence on the Moon and to develop the resources of the Moon for long term exploration, and to use the Moon as a proving ground for future human missions to Mars. Like President Kennedy’s Moon challenge, Artemis represents a real mission which could unite this country, jumpstart our economy through new fundamental scientific discoveries and technological advances—in a word, ignite the talent, creative imagination, and thirst for discovery which once made America great.
President Trump brought NASA back from the scrapheap after the destructive policies against NASA under Barack Obama. At that time and continuing, based on his influence over the Biden Administration, Obama used NASA to pursue “evidence” to back up the utterly fabricated claim that we face imminent catastrophic climate disaster, requiring a societal reordering taking the economy back to feudal times, but in a way deemed “equitable” under Critical Race Theory’s edicts.
Manned space exploration and discovery were shelved. That's the primary reason why both Lyndon LaRouche and I devoted ourselves to a campaign for Obama’s impeachment. Now, rather than directly opposing the wildly popular Artemis program, the sabotage plan seems to be to slow roll it into oblivion. As opposed to President Trump’s mission-driven approach with fixed deadlines being actually met and exceeded, bureaucracy and waste will be allowed to corrode and ultimately completely undermine the mission.

We are now told that it is basically impossible that the space suits will be ready for flight before April 2025 at the earliest. According to the IG’s report, “for the past 14 years, NASA has been developing next generation space suit technology, which 5 years ago led to the creation of the project known as the Exploration Extravehicular Mobility Unit (XEMU) that will be used to support astronauts' involvement in multiple programs.” Astronauts aboard the International Space Station, ISS have continued to use the space suits designed 45 years ago for the Space Shuttle program.
NASA started working with Hamilton Standard and ILC Dover back in 1974 for the EMU design. During the Apollo program NASA contracted hundreds of companies including International Latex Corporation ILC of Dover DE, which manufactured Playtex bras and girdles because of the engineers understanding of rubber garments. NASA has continued working with ILC Dover on spacesuit design. In 1990 ILC Dover produced the suit currently being used on the ISS for spacewalks.
Despite working on the development of its Next Generation space suit for well over a decade, according to the IG, and having spent nearly $200 million on Extravehicular Spacesuits developed over the 9 year period which ended in 2017, “the agency remained years away from a flight ready space suit.” Since 2017, NASA has also spent an additional $220 million for a total of $420 million on space suit development.
I won’t waste more of your time or mine with the phony bureaucratic nonsense they give as to why the suits will not be ready. According to the IG, by the time two flight-ready XEMUs are available, NASA will have spent over a billion dollars on the development and assembly of the next generation spacesuit.
In line with its devotion to fake ideologies about climate change and human identity, the Biden collective cut manned space exploration in its budget while prioritizing climate “science.” NASA’s employees have been subjected to the full load of destructive ideological programming, including critical race theory, racial equity, and gender fluidity. Maybe that is why they have a delay in the spacesuit designs: They have to fit the suits to changing identities and gender pronouns.
While SpaceX founder Elon Musk has offered to help with producing the next generation spacesuits, and Musk has demonstrated his competence by returning American astronauts to the ISS on American rockets, from American soil for the first time since 2011, NASA and the nation as a whole are facing much bigger problems.
What is missing is the dedication to a renewed national mission of scientific discovery, of conquering and changing “nature” for the better, as was intended under President Trump’s Artemis Program. Such a mission, as President Kennedy noted, mobilizes the best of all our nation’s skills and talents. During President Trump’s time in office we were already making tremendous gains in achieving the goals of the Artemis mission through much needed advancement in a pro-nuclear policy for powering ourselves on earth and eventually on missions to the Moon and Mars. This is the critical element in restoring the United States to a full set advanced manufacturing economy, and reviving America as an industrial and manufacturing superpower.
Lyndon LaRouche’s Moon-Mars Colonization program, like Alexander Hamilton’s Report on Manufactures, like Abraham Lincoln’s Civil War building of the transcontinental railroad, and Franklin Roosevelt’s war mobilization, teaches us that massive scientific and technological mobilizations, focused on discovery and invention, drive human development and are the keys to a new American renaissance. Those now slow rolling Artemis are the same budget cutters, radical environmentalists, and faceless bureaucrats who have annihilated the physical and productive economy of this country, destroying the nation’s fabric and substituting a post industrial, decadent cultural dystopia. It is imperative that Artemis stays on schedule and that those responsible for the delays be removed from any decision-making role in our government. | aerospace |

METAL ROLLING PROCESSES Metal Rolling Shape Rolling Thread Rolling Rotary Tube Piercing MANUFACTURING PROCESSES Metal Casting Metal Forming Metal Forging Metal Extrusion Metal Drawing Sheet Metal Powder Processes
Ring rolling is a particular category of metal rolling, in which a ring of smaller diameter is rolled into a precise ring of larger diameter and a reduced cross section. This is accomplished by the use of two rollers, one driven and one idle, acting on either side of the ring's cross section. Edging rollers are typically used during industrial metal rolling manufacture, to ensure that the part will maintain a constant width throughout the forming operation. The work will essentially retain the same volume, therefore the geometric reduction in thickness will be compensated for entirely by an increase in the ring's diameter. Rings manufactured by ring rolling are seamless. This forming process can be used to manufacture not only flat rings, but rings of differently shaped cross sections as well, producing very precise parts with little waste of material.
A significant advantage of parts produced by this metal rolling process is that the forming of the material will impart the ring with a grain orientation that gives it enhanced strength relative to most applications. Common items produced by this process in manufacturing industry today include rings for machinery, aerospace applications, turbines, pipes, pressure vessels, roller and ball bearing races. The following shows the sequence of events of the ring rolling process, the part is commonly started as a metal bar cut to a certain length. | aerospace |

While he was fascinated by what he read, Prewitt didn’t think there would ever be a way for him to travel and see the world firsthand.
Then a few former Oliver High students came home to visit while on leave from the Air Force, and Prewitt was so impressed with their stories, he decided to try the military himself.
It was a decision that led to visits around the world, from Hawaii to Greenland to the North Pole.
On May 28, 1954, 17-year-old Prewitt graduated from Oliver High, and enlisted in the Air Force the next day.
“I turned 18 in French Morocco, and I went to Paris and London,”¿Prewitt said in a phone interview from his home in New Jersey.
For an African-American man in small town Kentucky, Prewitt said the Air Force presented opportunities he might never have had otherwise. His 20-year career began with basic training at Sampson Air Force Base in New York, and technical training at Keesler Air Force Base in Biloxi, Miss. His first assignment was as a radio operator on a refueling plane, based at Castle Air Force Base in Merced, Calif.
“I was responsible for all the air-to-ground communications as an airborne radio operator. The most notable activity was air refueling one of the Air Force’s first B-52s,” Prewitt said.
His work as a radio operator took him to Dow Air Force Base in Bangor, Maine, where he flew on missions to Newfoundland, Greenland, and even the North Pole.
By 1959, he was transferred to Tachikawa Air Force Base in Japan, where he flew with the 6th Troop Carrier Squadron. By that time, technology had changed and pilots were operating radio equipment themselves. Prewitt was offered the opportunity to cross train, and he opted to become a loadmaster.
Another transfer led him to Travis Air Force Base in Fairfield, Calif., in 1962. His duties included regular flights to Cape Canaveral, Fla., transporting missiles for NASA, including the first Gemini booster rocket and the Atlas missile.
Prewitt said he was fortunate because he rarely encountered overt racism within the military. When traveling, he stayed with friends or on military bases and avoided situations where there was the possibility of discrimination. At Cape Canaveral, however, there was no military base, and Prewitt found it difficult to find food and lodging.
“There were no facilities for an African-American. The government had entrusted me with a multi-million dollar aircraft, and a multi-million dollar rocket, but I couldn’t go to a restaurant to get a sandwich, nor could I go to a hotel or motel and get a room,” Prewitt said.
Growing up in Winchester, Prewitt was aware of racial discrimination, attending the segregated Oliver High School.
“It’s frustrating right now to even think about something like that taking place, but during that time, we were going through a lot of turmoil, so we just had to accept it and go along with it,” Prewitt said.
Within the military, soldiers typically respected one another because they relied on each other to complete their jobs. Racism was less obvious, Prewitt said, like passing over African-American soldiers for promotions.
When President John F. Kennedytook office in 1961, Prewitt said there were some noticeable changes in the way African-Americans were treated, but attitudes didn’t really change along with the laws. Public facilities may have been more open to African-Americans, but many people still clung to racist ideologies.
Prewitt was stationed at Travis until 1965, where he met his future wife, Joanne, and the couple married in 1967.
After leaving California, Prewitt was sent to Da Nang Air Force Base in Vietnam. At that point, Prewitt was a 10-year Air Force veteran.
“Our mission was to resupply any and all areas that needed our services. We did that resupply via take-offs and landings or aerial delivery,” Prewitt said.
In Vietnam, Prewitt logged 824 combat sorties, take-offs and landings in hostile areas, and 522 hours and 22 minutes of flight time.
He was also the only African-American on his crew.
“It was easier in Vietnam only because we actually had to depend on one another both on base and off to exist. You didn’t know when you had to come together to protect one another. Here in the United States, we knew who was who, and you avoided whenever possible, those type of individuals,” Prewitt said.
There were a few incidents when Prewitt encountered other soldiers off base.
“Every once in awhile, we would go into Saigon, and you would run into some racist comments from your own military people,” Prewitt said, although “no one would dare do that on base.” | aerospace |

Those included the C-130 Hercules; C-105 Amazonas; SC-105 Amazonas SAR; C-95 Bandeirante; E-99; A-1 AMX; A-29 Super Tucano; H-36 Caracal; MI-35 AH-2 Sabre; and H-60L Black Hawk helicopters. In all, aircraft logged in around 1,200 flight hours. The 5th Wing’s base in Campo Grande, in the mid-western Brazilian state of Mato Grosso do Sul, served as the backdrop for the exercise. FAB Colonel André Luiz Alves Ferreira, co-director of the exercise and head of the Operational Preparation Control Division of the Preparation Command (COMPREP, in Portuguese), said the choice for the first edition of Tápio was far from random. “The 5th Wing is very versatile and encompasses organizations capable of undertaking search and rescue operations, air defense, tactical transport missions, and special operations,” Col. André Luiz told Diálogo. “In addition, the surrounding region has very favorable climatic conditions at this time of year and a geographical area with appropriate characteristics to conduct the exercise.” The objective of the activities, Col. André Luiz said, was to train aerial squadrons and infantry units in combined operations. “The focus was on a wide-ranging and rational training exercise, based on a realistic and up-to-date operational scenario. If, in the future, FAB becomes engaged in UN peacekeeping missions, this training will be very useful,” he explained.. In addition to FAB service members, four members of the Brazilian Army and four from the Brazilian Navy participated in EXOP Tápio. Service members acted as forward air controllers, coordinating aerial attack missions on targets within a defined area. “It was an excellent opportunity to undertake joint missions in an exercise under FAB’s control,” said Col. André Luiz. Composite aerial missions Air squadrons and infantry units took part in the Air Force’s most important missions. The missions included close air support, forward air control, escort, aerial reconnaissance, aerial infiltration and exfiltration, combat SAR, aerial medevac, air assault, and counter-air defense, among others. “We started with some doctrinal guidelines to disseminate important operational concepts about the flights themselves. Aerial activities began on the second day and, according to design, their complexity evolved gradually, until we executed composite air operations (COMAO),” said Col. André Luiz. FAB Major General Augusto Cesar Abreu dos Santos, exercise director and commander of 5th Wing, said the greatest benefit of Tápio was COMAO. “They involve around 20 aircraft which take off together and fulfill certain objectives; coordination is essential and very complex. We were successful in more than 90 percent of the simulated training scenarios,” he told the Air Force Press Agency. Quality of training benefits squadrons “An exercise involving 26 squadrons operating together is no routine event; therefore, the exchange of experience and the lessons learned during these missions allow us to grow operationally,” said FAB Lieutenant Colonel Luciano Antônio Marchiorato Dobignies, commander of the Second Squadron of the 10th Aviation Group. “The Tápio exercise provided participating units with valuable doctrinal and operational lessons,” he added. The Pelican Squadron, part of the 5th Wing, took part in EXOP Tápio with 100 of its 130 service members. The team flew 384 missions, mostly combat SAR and close air support, the unit’s specialties. Of these, 17 missions fell under the SC-105, an aircraft configured for SAR missions. “We also took part in the general coordination of the exercise, especially in planning combat SAR missions and providing tactical pre-hospital care,” Lt. Col. Marchiorato told Diálogo. The role of the Pelican Squadron during Tápio was to assist in the rescue of a crew-member brought down in hostile territory. Two helicopters and their crew extracted and provided medical care to the victim and two to four helicopters (AH-2 Sabre) or fixed-wing aircraft (A-29) escorted the SAR rotary-wing aircraft. “The aircraft took off in a coordinated manner so that the helicopters were continuously covered against ground-based threats. The SC-105 flew high, outside the range of any ground-based threats and provided updates on the overall situation on the battlefield and the condition of the evading service member using electro-optical, radar, and personnel locator systems. The mission was considered a success when the evading service member was rescued and all aircraft returned to safety,” explained Lt. Col. Marchiorato. Objectives attained Col. André Luiz believes that the first edition of the training exercise fulfilled its objectives. “We standardized the doctrine conceived, trained the crews in all planned air force missions, and learned a number of lessons that will be important for future exercises.” In addition to Tápio, COMPREP planned two major conventional warfare exercises: Tínia, a land-based exercise, and Caríbidis, to take place in a tactical maritime environment. “Our idea is to hold two of these three EXOP every year, to be defined in accordance with command aspirations and prior analysis for priority and need for training,” Col. André Luiz said.
In what they charge to be the new home of their recently retained ISSA-FLOW Manning Cup title, three-time consecutive holders Jamaica College celebrated fervently at their morning devotion inside the Karl Hendrickson Auditorium at 189 Old Hope Road yesterday.The victory was described as their sweetest, as administrative staff, players and well-wishers gushed, clapped, cheered and sang loudly.JC triumphed over perennial rivals St George’s College in a very close 1-0 match at Sabina Park, St George’s backyard, last Saturday.”We gathered at the school a couple Mondays ago to do some reflection. The Griffin (JC crest) was wounded, but the Griffin has risen again,” said principal Ruel Reid.His team had recently been thrashed 4-0 by St George’s in the FLOW Super Cup.However, JC emphatically rebounded to defeat their rivals on Saturday courtesy of Donovan Dawkins’ 88th-minute goal.”This is one of my proudest moments as principal of this great institution. For 33 years, JC had not won the Manning Cup. Since 2007, we have been to seven semi-finals, six finals and won five championships,” Reid said to resounding applause and cheers.”We are a dynasty. We are gonna make history. It’s gonna be a long, long, long time before anybody beats us,” he warned.”One College, the ‘True Blue’ College, has risen victorious,” he added in obvious reference to the shade of similar colours among the combatants – with JC referred to as the ‘Dark Blues’ and St George’s, the ‘Light Blues’.Amid the euphoric celebrations, captain Allando Brown paraded his team on the platform, where they held the trophy aloft.Citing Psalm 136, Vice-Principal Rohan Wong told the audience: “Give thanks to the Lord, for he is good. His love endures forever.”The Lord redeemed us in the final and gave us victory over St George’s College. His love endures forever,” Wong continued.Michael Bernard, chairman of the school board, said: “No mishap can allow us to believe that St George’s College was better than us. We have not lost a Manning Cup in three years. We are the defending champions. St George’s lost two Manning Cup games this year before meeting us in the final. How could they be better than us?” he questioned, to rapturous applause.Team manager Ian Forbes believes JC celebrated not only a trophy, but the emphatic way in which it was done, without losing a Manning Cup game since 2012.”This is our sweetest one to date. Three straight hasn’t been done in 52 years, and after being buried by a lot of persons, we found the resilience and determination and discipline to beat a team that many said were unbeatable,” Forbes told The [email protected] | aerospace |

This was drawn mainly from an interview with Ron Roth, Product Manager—Airborne Topographic LiDAR for Hexagon’s Geospatial Content Solutions. The discussion touched on the addition of single-photon technology to Hexagon’s portfolio—and that’s where the article ended—but then Stewart spent time with founder and CEO of Sigma Space, Dr. Marcos Sirota, after which Ron hosted a tour of the assembly and test areas of the production facility in Lanham, Maryland. This is the sequel, therefore, and describes what Stewart discovered at Sigma Space.
Editor’s note: A PDF of this article as it appeared in the magazine is available HERE.
Single-photon: setting the scene
Sigma Space’s Single-Photon Lidar (SPL) technology has been well reported in these pages before, by Dr. Stephen Mitchell , formerly director of mechanical engineering at Sigma Space and now with University of Maryland College Park (UMCP). At the time of my visit the ATLAS sensor for the NASA mission ICESat-2 had passed its tests at NASA Goddard Space Flight Center (GSFC) and was on its way to Gilbert, Arizona, for integration on to the spacecraft by its constructor, Orbital ATK (now Northrop Grumman). The launch took place on 15 September 2018 and LIDAR Magazine was in attendance!
Ron summarized the motivation for the acquisition of Sigma Space as the potential to accelerate the commercial applications of SPL technology. The ongoing business of Sigma Space was focused on clients such as DoD and NASA. Sigma Space had many successful single-photon instruments in operation and a proven capability to construct operational instruments at low production levels. Leica Geosystems saw this as an opportunity.
The advance of linear-mode lidar is constrained in some ways by eye safety. Using two lasers is not a reasonable solution. It is not possible merely to fly at the same altitude and increase laser power to achieve higher pulse rates without suffering consequences in eye safety due to that increased output. If it is not possible to use more power, an alternative is to increase the size of the receiving optics, but this increases the size and weight of the airborne system. The better solution is to increase the sensitivity of the receiver, with the result that the pulse rate can be increased without requiring more power. This is where single-photon comes in—the receiver can detect as little as one arriving photon. The Leica TerrainMapper, for example, which is the latest model in the linear-mode lidar product range, uses a 20W laser to acquire 2 million points per second, i.e. 2 million effective laser shots per second (2 MHz). The ALS80 uses a similar 20W laser at 1 MHz effective pulse rate. The SPL100, however, obtains 6 MHz effective pulse rate from a 5W laser. The innovative underlying technology, through breaking up a single laser output into 100 beams, is capable of a pulse rate three times greater than that of TerrainMapper with one quarter of the laser power, i.e. is more than an order of magnitude more sensitive on the receiving end, giving extremely high effective pulse rates from a relatively small laser. Leica Geosystems appreciated the market requirement and knew that Sigma Space had the know-how.
I asked Ron about the other exciting new lidar technology, Geiger-mode. He replied that, like single-photon, it uses a 2D array of detectors. However, unlike Geiger-mode, single-photon acts more like an array of linear-mode systems, making range measurements to intercepting surfaces at multiple ranges from a single output laser pulse, whereas Geiger-mode is limited to a single return per pixel per laser pulse. In order to overcome this limitation, Geiger systems work in a “photon starved” mode, with a very low probability of detection per pixel per pulse, and rely on dramatic repeat-sampling to separate signal from noise and improve accuracy. Leica Geosystems perceived that single-photon was a superior technology and pursued it. It recognized opportunities for using the technology in wide-area acquisition, for example for the HxGN Content Program.
I invited Ron to explain the implementation of single-photon technology in the SPL100 in more detail. One of the great advantages of SPL systems is a very short detection reset time, or minimum return separation in terms of vertical distance, which currently permits 24 cm range discrimination between separate targets. This is similar to that of the latest linear-mode systems, though better than the ALS80, for which the corresponding figure is >1 m. It is very suitable for acquiring the ground in low-brush—on a par with the full-waveform linear-mode systems. This makes single-photon technology very competitive. Ron repeated that Geiger-mode is limited by significant amounts of repeat looks at the same target and setting low detection probabilities of perhaps 35% or less. That means a probability of only 35% of detecting a returning photon: sensing all the vegetation as well as the ground is challenging without considerable repeat-sampling.
Ron enthused over single-photon being analogous to 100 linear-mode systems in parallel. I probed further by asking whether single-photon technology can provide intensity values. Ron explained that multiple photons from a single return produce a wider pulse at the detector. It is possible to time the leading and trailing edges of the incoming signals. Intensity is derived from the return pulse width and Sigma’s SPL timer is capable of resolving the leading and trailing edges of each return with 80 picoseconds (ps) resolution.
The wavelength of the laser in the SPL100 is 532 nanometers (nm), though others are possible. This is partly historical: earlier generations of photo-multiplier arrays, which were used in early products, had peak sensitivity in the visible. One advantage of 532 nm is water penetration, but as yet there are no algorithms in the SPL100 software to exploit this, e.g. water surface detection, refractive ray bending, speed of light change, so the system is not targeting bathymetric applications. Moreover, the SPL100’s canopy penetration is rather good. Some of the earliest single-photon systems were designed for that: it behaves like a multi-return linear-mode lidar for detection of forest floor. We moved on to geometric accuracy: delivered data, after calibration and registration, is stated to be in the 5-10 cm accuracy range in terms of RMSEZ. Leica Geosystems has made amazing progress in terms of achievable accuracies. The point density, usually measured in points per square meter (ppsm), is based on effective pulse rate, flying height, flight speed, wedge angle etc., allowing users the flexibility to tailor operating settings (within limits) to the point density requirements.
The SPL100 was not fully productized by Sigma Space at the time of acquisition. Thus re-engineering began immediately. Leica Geosystems approved the building of several units as part of productization. The sales network and content programs were activated in a “controlled rollout” mode for the SPL100, while experience was being gained. Existing Leica Geosystems components were integrated into the system, e.g. PAV100 gyro-stabilized mount, RCD30 medium-format frame camera, FlightPro software for mission execution, and MissionPro software for mission planning. Collectively, these Leica Geosystems components are known as the Common Sensor Platform, including pilot display, operator display, GNSS/IMU, data logging, and stabilized platform. The SPL100 is built in the Sigma Space facility in Lanham, whereas the Common Sensor Platform comes from Heerbrugg, Switzerland, where products such as the ALS80 and TerrainMapper are manufactured.
Leica Geosystems is transitioning the SPL100 into a fully commercialized system and is conducting pilot projects with partners, e.g., Woolpert in South Dakota early in 2018, and sample projects in Europe, e.g. the region of Navarro in northern Spain. Ron estimated that these systems are a minimum of 3x, but more likely 6-10x, as productive as linear-mode, which can achieve 2 MHz only up to certain flying heights. Woolpert, which has a long history of working with Leica Geosystems and Sigma Space, flew the SPL100 in Hawaii, where it performed well over lava fields with relatively low reflectivity.
As we neared the end of the session, I asked Ron to speculate on the value of single-photon technology for TLS or MMS systems. He felt there could be some. He said one company makes a single-photon lidar for UAVs—so small units for terrestrial use should be feasible. There’s no particular reason why the technology can’t be miniaturized.
The story of Sigma Space
I joined Marcos in his office to talk about Sigma Space and its history. The company was founded in 1997 to make optical instruments for aerospace. It began with the NASA ICESat mission, which carried a linear-mode waveform lidar. Born in Argentina, Marcos completed his PhD at the University of Washington in 1989, went to NASA as a post-doc, then worked at GSFC and University of Maryland Baltimore County. Sigma Space’s operations began in April 1998. His aspiration was not a classical service supplier but a company that created technology. He perceived a void amongst NASA suppliers for constructing and designing systems from proof of concept technical readiness level 6 (TRL6: a technology is usually tested in aircraft before it is used in space). His idea was an engineering development company working in cooperation with NASA. Sigma Space started to work on single-photon sensitive technologies early on, first on an airborne lidar for the measurement of cloud physical properties with Dr. Matthew McGill, and, soon after, on the commercialization of the Micropulse Lidar, a ground-based instrument to measure cloud and aerosols, developed by Dr. Jim Spinhirne. Dr. John Degnan, who became Sigma Space’s chief scientist in 2003, was at NASA at the time, and Sigma Space worked with him on the first single-channel and four-channel single-photon terrestrial altimeters. A patent was filed and a license exists today. GSFC launched the Mercury Laser Altimeter (MLA) in 2004. At the time the laser altimeters going to space were conventional, single-channel (i.e., just one beam), linear-mode lidars.
Sigma Space’s first success for their technology was a USAF Small Business Innovation Research award, for a 100-beam system (not unlike the SPL100) capable of operating at 3000′, which flew in 2006. Marcos had a very good electronics group, which designed the timers, truly the core of the instrument, and the result was a resounding success according to the Air Force Research Laboratory (AFRL) program manager, Richard Richmond. They found a plane nearby: UMCP had an aircraft with a hole for a sensor, since it had been testing instruments for USAF. Sigma Space flew and tested the instrument rather ahead of the schedule expected by the more formal AFRL. USAF, GSFC and UMCP were all very enthusiastic about the results. The system, known as Leafcutter, was later flown over both forest and ice, for example over Greenland, the data going to NASA. The University of Texas purchased a copy of the system for its Antarctic campaigns. After Leafcutter came Mini-ATM for NASA to monitor Greenland’s ice sheets, intended to fly in a UAV. There were also various scientific instruments, mainly for NASA, which were not lidar but contributed to the intense build-up of expertise in the company.
A current version of the technology was selected for the instrument for ICESat-2—SPL is in space! The instrument is the Advanced Topographic Laser Altimeter (ATLAS), which has six beamlets. To create datasets similar to those to be measured in space, Sigma Space collaborated with NASA to build an instrument called Multiple Altimeter Beam Experimental Lidar (MABEL) for tests on the ER-2 aircraft at 65,000′, sufficiently high to have most of the atmosphere below the aircraft. The first of these flights was in 2010. MABEL was a GSFC project, but Sigma Space was very involved, providing electronics, mechanical assembly and more. A fundamental component of the instrument for ICESat-2 is the timing electronics, developed by Sigma Space. In addition Sigma Space provided the opto-mechanical components for, and built in-house, the laser pointing and boresight determination system, the ATLAS Laser Reference System. The principal investigator for the ER-2 mission was Dr. Matthew McGill. The project scientist for ICESat-2 is Dr. Thorsten Markus.
Marcos and I very briefly talked about automotive applications, but returned quickly to aerospace. Around 2011, Marcos decided to go for something more powerful than Leafcutter, upgraded for higher altitude, so Sigma Space built the HRQLS-1 (pronounced “hercules”), capable of operation at 7000′ with 50 cm pixels, giving a density of 8 ppsm in a single pass. This was used, for instance, for a Connecticut collect for USGS, flown in 2015. The purpose was the validation of the technology for the USGS 3DEP program.
Also, around 2011, Sigma Space worked with Woolpert to design and engineer a High Altitude Lidar (HAL) system for use at altitudes greater than 25,000’. Although Sigma Space SPL systems were operating at only 3,000’ when it initially become involved in HAL, the company saw that the high altitude system was feasible and signed up to build it. A requirement for this project was that the system had to be mountable in a wing pod, restricting form factor and mass. Ultimately, the system was tested and achieved initial operating capability (IOC) status after hundreds of hours of flight testing and the development of two prototypes. As a result, Sigma Space has built five instruments, three in the same configuration as the first, and two under Leica Geosystems, named the SPL100HA, which is similar to the commercial instrument, SPL100, but has a higher power laser so it works at higher altitudes. The two SPL100HA units were delivered in December 2017, capable of operating at 200 kts and up to 30,000′.
From HRQLS-1, Sigma Space advanced to HRQLS-2, still with 50 cm footprint spacing within the 10 x 10 array, but with a bigger laser to enable operation at 12,000′, which offered advantages in terms of air traffic control. As they were finishing HRQLS-2, a positive report was announced by USGS on HRQLS-1. Sigma Space participated in the ILMF conference for three years and Leica Geosystems became interested in the new technology. The HxGN Content Program was a major driver, too. Today, the SPL100 is offered to partners as a tool for content generation. The partners can perform as much of the workflow as they want, for example flying and processing, or just flying. Sometimes Leica Geosystems flies the instrument itself, using Northwest Geomatics’ aircraft, or a partner aircraft, or Dynamic Aviation, which also carries out many of the test flights of Sigma Space’s DoD instruments.
Sigma Space was seeking a large partner to put the technology to greater use. Sigma Space had also considered data services, so there was a meeting of the minds between the two companies. The deal became a full acquisition, however, to satisfy stakeholders such as the workforce, which was very necessary both on the commercial side and for NASA work—there was no obvious dismemberment to fit the bill. Sigma Space was acquired in early 2016 by Hexagon as a subsidiary of Leica Geosystems. Recently, operation of Sigma Space was transferred to Hexagon US Federal, the arm of Hexagon doing business with the federal government and DoD. There is already a long history and much experience of defense work at Hexagon Federal, starting from the federal systems arms of ERDAS and Intergraph. Nevertheless, Sigma Space will continue to produce instruments for Leica Geosystems and develop commercial technology jointly with Leica Geosystems. Marcos is very proud of what has been accomplished.
I raised the issue of intensity values, just as I had with Ron earlier in the day. Marcos explained that intensity, by definition, is the number of photons that return—what a linear-mode system records. Single-photon systems work with 100 beams that are like linear-mode but with fewer photons and much more sensitive detectors. Thus the returning signal does provide a measurement of intensity on a per pulse basis. By contrast, Geiger-mode has to do this by repeat-sampling: those systems have low probability of return. Only after the Geiger-mode system fires many shots at a particular point on the ground can it retrieve an “intensity” based on the number of returns versus number of pulses fired. But this is very processing-intensive. It is also very dependent on the GNSS/IMU accuracy.
I also asked about the bathymetric side and Marcos said there are export restrictions in play, depending on the capability of the system—bathymetric surveying has become very sensitive worldwide. Sigma Space has not developed any bathymetric capabilities or software. Bathymetry is also a difficult problem (what’s happening to 100 beams under the water, both on the surface and in the water column, plus the refraction issues), so Sigma Space will refrain from this market unless Hexagon uncovers some unexpected market requirements. Also, Sigma Space is moving to use 1064 nm, so water penetration will no longer be possible, though this change will help for generating breaklines at the land/water interface. There would be some advantages in an even more radical change, to 1550 nm, but Marcos argued that this is not so good for some applications. So 1064 nm is a comfortable choice on both physics and engineering grounds. I similarly repeated my question on TLS or MMS possibilities. Marcos said there are some reasons to develop SPL for such applications.
Does vertical accuracy remain the same as you fly higher? Marcos gave further explanation. Altitude does not affect timing accuracy. The accuracy of 3D points depends on the accuracy of both timing and geopositioning. As you fly higher, the vector is longer, so the results are directly affected by the performance of the GNSS/IMU system, but mainly in X and Y rather than Z. Timing is the biggest influence on Z. What influences timing? The length of the pulse of the laser is an important factor—the sharper the better—and is a function of the physics of the laser. There is jitter in the detector and jitter in timing. These factors are all the same at 25,000′ as at 3000′. Thus the error source that is worst affected by increasing altitude is geolocation.
Sigma Space SPL timer resolution is 80 ps, but 2 ps has been achieved for a NASA project. And the next generation timer is in the making. Hexagon has a European partner which has demonstrated the SPL100 to acquire data for infrastructure. Demonstrations are necessary because the process to start a national campaign is long and complex. The data can be used for construction and engineering work. In these applications, much higher spatial resolutions could be helpful given the level of detail that could be requested. The recognition of types of trees, as in a recent Minnesota collect, would benefit from higher resolution too. Thus, much higher data rates or “points per second” are in the plans. With the spread of GPUs, moreover, processing costs will fall considerably. Sigma Space is also moving towards real-time processing.
We spoke about ILMF and its power as a platform for the proselytization of new technologies, attracting the best speakers on the development side as well as the professional. Marcos concluded our enthralling discussion with the comment, “It [ILMF] has achieved a very high scientific content.” Yes, indeed.
On the shop floor
After lunch, Ron took me on a tour of the laboratory, where Bruce McCready showed me a system in the testing process. I noticed similarities to the ALS systems that I remembered from years ago, in terms of the rack arrangement and the complex wiring for power distribution, but of course the overall appearance was much more modern and sophisticated, including the Leica CC33 Camera Controller, GNSS/IMU and data logger. There is both flight planning and flight execution software. They still use a laptop to control the SPL100 sensor, because the sensor GUI is not integrated in the Leica FlightPro software, yet. Once it is incorporated, however, data will go straight to the Camera Controller, a useful simplification. Ron added that, while many ALS customers do not use a gyro-stabilized mount, all SPL100 customers do due to the higher flight altitudes.
A silver box on the sensor head contains the 5W laser, similar in physical size to the one used on the ALS80. While the standard SPL100 uses a 5-watt laser, the HAL and SPL100HA systems are designed for operation at greater flying heights and use a 15-watt laser. Ron pointed out that, while the lasers in linear-mode systems such as the ALS80 output laser pulses of 3 ns duration, SPL technology uses pulses as short as 100 ps. This simple comparison highlights the innovative nature of the Sigma Space technology.
Ron returned to work and I spent the remainder of the day with Sigma Space scientist Claudia Carabajal, who works as a NASA contractor and has been heavily involved in ICESat, ICESat-2 and other missions. She took me on a memorable tour of GSFC, during which I saw instruments in testing as well as the workspace where the ATLAS instrument for ICESat-2 had successfully completed its tests before being shipped to Arizona. I met several brilliant NASA scientists, including Scott Luthcke, who gave a spectacular closing keynote at the ILMF conference in Denver in February—and will give a repeat performance, by popular request, at the January 2019 event. Claudia is writing an article on spaceborne lidar for LIDAR Magazine.
As noted in my editorial in this issue, I was privileged to attend HxGN LIVE in Las Vegas in June 2018. During the hectic four days, I was awarded a generous time-slot to talk to Bruce Wald about the HxGN Content Program. Bruce’s business expertise provided insightful perspectives and I hope that we can cooperate on an article on this topic, which will be the fourth and final one in this series.
The main purpose of the day, however, had been fulfilled. I had caught up with Ron Roth and seen the ongoing integration of Sigma Space into Hexagon. I had had the honor of more than an hour with Marcos Sirota and now understood some of the brilliance, motivation and sheer scientific and engineering excellence and innovation that undergird the achievements of Sigma Space and have rendered it so very attractive to its new owner. There is no question that the Sigma Space instruments, with their capability for higher altitudes, higher flying speeds and faster data acquisition, will enjoy a growing role, not only in terms of instruments sold to customers within Leica Geosystems’ traditional business model but also as resources for valued partners in the content program. Similarly, the company’s role in space and defense programs seems bound to expand—the future is as bright as it is intriguing. | aerospace |

King Salman is visiting with a huge delegation of around 600 staff, ministers and officials. The King and his delegation arrived at Kuala Lumpur International Airport (KUL) in three special aircraft earlier today.
The KUL plane-spotting community was out in force to catch the arrival of these special aircraft.
The King himself along with his close associates arrived first in the Saudi Royal Flight Boeing 747-400 registered HZ-HM1. The callsign was “Saudi One”
The second aircraft to arrive was the highlight of the day. Carrying the Saudi delegation was the Saudi Royal Flight Boeing 747SP, registered HZ-HM1B. The callsign was “Saudi One Bravo”
We were lucky to spot this rare 39 year old classic as it touched down on Runway 32L.
The final aircraft in the delegation was the Saudi Royal Flight Boeing 757-200, registered HZ-HMED, and callsign “Saudi 11”.
This is an interesting aircraft as it is practically a flying hospital. This aircraft is equipped with facilities and personnel to cater to any medical emergencies that might occur.
As you can see, this was a great opportunity to spot some rare special aircraft. Enjoy the photos! 🙂 | aerospace |

And that’s without the camera
Almost a year has passed since the appearance of the first information about the drone GoPro Karma, and now the device is announced.
Wish drone would cost $800. In the case of purchase jointly with a camera or Hero5 Hero5 Session, which we will cover later, the cost will rise to $1100 or $1000, respectively.
Karma — folding drone. But, as you can see in the image, it still takes so little space, and transport it is better in the native case. Also, the aircraft received an unusual remote control, similar to a portable gaming console. He even has a touch screen.
Karma has its own triaxial stabilizer to mount the camera. Moreover, this stabilizer can be detached and used separately. GoPro says work with the Hero Black cameras 5, Session 5 Hero and Hero 4.
If we talk about the possibilities of drone, it is capable of speeds up to 56 km/h, removed from the pilot at a distance of 1 km and rise to a height of 4.5 km. Karma can fly at a wind speed of 10 m/s. drone’s dimensions are 303 x 411 x 117 mm weight 1 kg Battery allows the new product to stay in the air for up to 20 minutes. | aerospace |

The two spacecraft will be launched from China’s new satellite launch center in Hainan province, which is expected to come into use later this year.
Tiangong-2 will be used to test and verify refuelling and propellant technology, regenerative environmental control and life support technology in order to lay the foundations for the construction of China’s planned space station, which the country aims to put in orbit by 2020.
The Tiangong-2 laboratory module was originally designed to be a backup to Tiangong-1, but recent changes in China’s manned space flight programme mean it will be redesigned to allow it to be refuelled by the unmanned cargo resupply vehicle, Zha Xuelei, deputy designer of the cargo spaceship revealed.
According to Zha, the 13-ton craft will be more than 9 meters in length with a largest diameter of 3.35 meters. It will be capable of carrying 6 tons of goods, three times that of Russia’s Progress cargo spaceship. It will be able to host a crew of three for up to 20 days.
It will also carry a mission payload including POLAR, a Chinese-Swiss collaboration project to detect black holes, conduct tests of quantum gravity theories and measure the polarization of
gamma ray bursts.
The construction of China’s fourth launch site near Wenchang, Hainan Province began in September 2009 and estimated to cost around 5 billion RMB (US$730 million), and offers the advantages being nearer the equator than other sites and being accessible by sea.

PT DI Plans to Sell More NC-212i Aircrafts, Thailand Will Be First Customer
TheIndonesia.id - State-run aircraft manufacturer, PT Dirgantara Indonesia (DI), plans to expand its sales to Thailand with the procurement of the NC-212i light transport aircraft for the Southeast Asian market.
President Director of PT DI, Gita Amperiawan, on Tuesday, highlighted the potential to sell eight NC-212i aircraft to Thailand.
"We plan to sell eight NC-212i aircraft to the Ministry of Agriculture and Cooperatives of Thailand," he stated after the handover ceremony of five NC-212i aircraft from the Indonesian Defense Ministry to the Indonesian Air Force at the Halim Perdanakusuma Air Base, as quoted by Antara.
Amperiawan remarked that the Philippines and Vietnam also bought the same aircraft from PT DI, with nine units and three units respectively.
Meanwhile, the Indonesian Defense Ministry ordered nine NC-212i aircraft from PT DI, five of which have been completed and received by the Indonesian Air Force, three units are scheduled for completion in 2024, and the other one is projected to be complete in March 2025.
The five NC-212i units will strengthen Air Squadron 4, Air Wing 2 of the Abdulrachman Saleh Air Base, Malang, East Java.
Minister Subianto noted that the domestic components level (TKDN) for the NC-212i was 40 percent, with most of its equipment being made and assembled in Indonesia.
Amperiawan then noted that some parts, such as engines, propellers, and aircraft avionics systems, cannot be made domestically.
"We do not have engines or propellers. That is quite big," he stated.
However, PT DI aims to explore collaboration to increase the company's ability to manufacture its own aircraft avionics systems.
"We are just starting to increase TKDN in avionics," he remarked.
At the handover ceremony, Minister Subianto lauded PT DI's achievements in being able to make aircraft domestically. He also directly reviewed the aircraft's condition.
"This aircraft is equipped with autopilot device, a glass cockpit, composite propeller, and avionics system. This plane can land on grass fields and sand fields with only a 600 meters strip. This plane is capable of working in difficult places with many functions," he explained.
According to Subianto, the multipurpose light transport aircraft could not only be used for training and troop transport but also for air medical evacuation, aerial photography, weather modification, and air navigation training. The aircraft is also equipped with a ramp door to accommodate cargo loading and unloading.
"Thank you to PT DI for always improving your abilities. The company has great determination to master technology for the sake of this nation's independence. Please continue to improve our nation's ability to master advanced technology," he remarked. | aerospace |

A flight of fancy.
A team from National Geographic, however, brought fiction to life. Scientists, engineers, two balloon pilots and dozens of volunteers built a light-weight 16 x 16 foot house, attached 300 helium-filled weather balloons (each of which is 8 feet tall when inflated) and managed to get the small house 10,000 feet into the air.
Setting a new world record for the largest balloon cluster flight ever attempted, the entire aircraft from top to bottom was a whopping 10-stories high, made it to an altitude of 10,000 feet, and flew for about an hour.
And yes, the house was inhabited when it took flight.

The stunning pictures captured during this mission have provided a deeper understanding of the universe and opened doors for further exploration.
These discoveries will undoubtedly lead to increased knowledge about our world beyond what we ever thought possible before. .
NASA’s latest mission aims to capture high resolution images of Black Holes and Galaxies
The United States National Aeronautics and Space Administration (NASA) has always been at the forefront of space exploration, sending probes, rovers, telescopes, and humans beyond Earth. Its latest mission is no exception - a project focused on capturing high resolution images of black holes and galaxies.
With the spacecraft launched in 2021 already beaming back incredible data – pictures that have never been seen before - this groundbreaking initiative is certainly living up to its potential. According to NASA scientists, it will continue for years to come.
Why Study Black Holes and Galaxies?
Black holes are among the most mysterious objects found in the universe. They are difficult to study because they emit no light or radiation but their immense gravitational pull affects other objects around them. Despite their elusive nature, black holes are believed to be crucial components in galaxy formation.
Galaxies comprise billions of stars that orbit a common center under gravitational forces. By studying these massive structures in detail, researchers hope to gain insight into how galaxies form over time and what factors contribute to their evolution.
Together with unprecedented advances in technology enabling us to explore ever more remote regions of deep space we can expect new discoveries about some of our universe’s biggest mysteries; what dark matter could mean for us here on earth; whether lifeforms exist beyond our planet - all stem from projects like this one being undertaken by NASA currently.
NASA’s Mission to Study Black Holes and Galaxies: A Detailed Look at the Technology Used
NASA, the American space agency, has been on a mission to study black holes and galaxies with an unprecedented level of detail. In order to achieve this challenging task, a technologically advanced spacecraft was designed and launched into space.
Launch Date and Location
The spacecraft was launched from Cape Canaveral Air Force Station in Florida on April 10th, 2019. This location is fittingly known as “The Space Coast” due to its rich history of space exploration missions that have been carried out there.
Objective of the Mission
The primary objective of this mission was to provide never-before-seen images and data of black holes and galaxies located millions of light-years away from Earth. Scientists hope that these images can help them understand more about these mysterious celestial objects, how they form, evolve, interact with their environment, etc.
Description of the Technology Used
To capture high-resolution images from deep space required state-of-the-art technology involving multiple telescopes working together in unison. The team used eight ground-based radio telescopes located all around the world plus two orbiting X-ray detectors called NuSTAR (Nuclear Spectroscopic Telescope Array) and Swift (Swift Gamma-Ray Burst Explorer) for enhanced imaging capabilities.
These were combined via a process known as interferometry. This allowed individual stations located across different continents to function like one huge telescope with exceptionally sharp resolution capacity; capable enough to even spot an orange on the moon! Such precision helped scientists observe effects predicted by Einstein’s theory of relativity such as warped spacetime near supermassive black holes.
In conclusion, NASA’s recent mission allowed scientists to get an unprecedented peek at what lies beyond our galaxy in stunning detail allowing us a better understanding about our universe which might lead us closer toward new technological advancements in various fields related to this area among others.
The images captured by NASA’s latest mission have revealed an unprecedented level of detail about black holes and galaxies. The high-resolution images allow scientists to study these objects in ways never before possible, providing new insights into the mysteries of the universe.
One of the most striking findings from the mission is the high-quality images of black holes. These images show details such as gas and dust swirling around black holes, allowing researchers to better understand their behavior and properties. Detailed studies of black holes are essential for developing models that can help explain some of the largest phenomena in our universe, such as how galaxies form and evolve over time.
In addition to black hole imagery, scientists were thrilled with their image quality on distant galaxies. By observing individual stars within these galaxies, researchers can determine various aspects such as mass, age and temperature more accurately than ever before.
These discoveries have profound implications for our understanding of the universe. By deepening our knowledge about black hole behaviours or galaxy composition can assist in explaining fundamental questions such as: How did our Universe come into existence? What is dark matter?
Moreover, this data could also lead to new technologies related to space travel or communication. For instance, studying astrophysical system behaviour might take us one step closer towards finding planets that support human life outside Earth’s solar system – exoplanets - while helping us develop technologies that would make intergalactic communications possible.
Overall NASA’s latest efforts help expand humanity’s understanding of our place in the cosmos further than ever before which will spur on scientific progress long after today’s headlines are faded away from public consciousnesses’.
NASA’s Future Missions and Conclusion
As researchers continue to investigate the mysteries of black holes and galaxies, NASA is planning several upcoming missions designed to further our understanding of these phenomena. One such mission will involve sending a spacecraft beyond our solar system to explore interstellar space.
Meanwhile, scientists are eagerly awaiting the launch of the James Webb Space Telescope, which is designed to capture even more detailed images of distant objects in space. With this powerful new instrument at their disposal, researchers hope to learn even more about black holes, galaxies, and other celestial objects.
Despite all we’ve learned so far about these fascinating areas of study, there is still much left to discover. But as NASA continues its exploration of deep space and beyond, we can be confident that new discoveries await us. In fact, some experts predict that we may be on the verge of uncovering entirely new laws of physics based on these findings.
Looking back at what we have already discovered about black holes and galaxies fills us with awe for the vastness and complexity of our universe. The knowledge gained from this research not only helps us understand the physical world around us but also sheds light on fundamental questions about human existence and limits.
In many ways, studying black holes and galaxies challenges us to think deeply about ourselves: how small we are in comparison with the universe’s scale; how limited our understanding remains despite advancing technology; how intertwined everything in nature is. As humans keep exploring deep space or discovering intricate parts within cells through microscopes - it becomes apparent just how complex yet beautiful life can be when closely examined. | aerospace |

I watched David Letterman last night, because he's funny as hell...
But, also, because he had the flight crew from Flight 1549 who landed in the Hudson River.
As a skydiver, and someone who has done some serious traveling on my own and with the military...
I've been on a lot of planes!
What this crew did is amazing. It's basically impossible to land in the water, and they pulled it off. They all have so much experience, and they are all really funny. You'd think it would be hard to laugh at this situation, but they are finding a way to do it.
They've done a ton of press recently, but Dave asked the questions that all of us would want to know the answers to... Like "Could you do it again"?
Check out the video...
We should all hope the crew on our next flight is as competant as they are!
You should probably read the safety card in the seatback, the next time you fly, just in case...
I bet you're not laughing that your seat can be used as a floatation device anymore, are you?

There are several different types of hold, and the altitude hold allows you to use it to ensure that you stay within set guidelines or to even get into hover mode, which will allow you to fly lower than normal.
The first type of altitude hold that you will see is a stabilized hold. If you want to be in hover mode, you should hold your RC helicopter up at an altitude where it would normally hover. When you are done with your hover move to a lower altitude and do the same thing.
In order to create a stabilized hold, all you have to do is adjust the position of your controller as you are flying and then stabilize your RC helicopter. Since this will add a little bit of play to your flight, you should try to fly slower and allow for smooth movements. Before long, you will start to feel comfortable with your handheld remote control and how to control the altitude hold feature of your Benyi RC Drone. This will help keep you safe and save you time.
Automatic hold is the next type of altitude hold that you will see. To perform this hold technique, you simply need to hold your RC drone at an altitude that would normally hover and then add a few degrees to your controller's axis. For example, if you were trying to hover at 400 feet, you would raise your controller's up to 900 feet. After doing this move, you would lower your controller's up again to 200 feet.
Manual altitude hold is a slightly more complicated technique. In order to create a manual hold, you need to hold your Benyi RC Drone at a lower altitude than you normally would in order to keep the system in the autopilot mode. Then when your hands go back to normal position, you can release the throttle and allow the drone to come back down to the desired altitude. If you did not do the proper procedure and hold at the right altitude, you could cause damage to your drone or have the robot become unstable.
If you want to perform a manual or automatic altitude hold, you should know that these two techniques are completely different. If you try to take your RC drone into manual altitude hold, you will need to open the throttle and allow the throttle to control the distance between the drone and the ground. If you fail to do this properly, you will destroy your drone! The easy way to prevent this problem is to make sure that you do not exceed a specific distance before allowing the throttle to return to its original position.
If you are attempting to create an altitude hold, you should make sure that your drone is in a place that is more stable and allows for easier manoeuvring. The best place to start is a level spot with a large amount of room and a low slope. This will ensure that your drone has a steady reference point and is flying at the right height. Once you feel that you have the drone in a place that will make it easy to hover, you can proceed to climb.
While climbing, you should slowly monitor the GPS and try to see what the terrain looks like. The terrain can vary from sand dunes, valleys, mountains and anything else that might exist. The main idea here is to keep the drone where it is in your initial position. Once you have a decent amount of height, you should begin to slowly pull back on the throttle and see if the drone can stay in hover mode. If it can, you can then begin to roll your drone to a higher elevation.
If your drone cannot hover or moves slowly while in hover mode, you should reverse the direction of your throttle and try again. This technique can get frustrating, so keep trying until you find a solution.
Once you have found a level place, you can now release the throttle and gently send the drone into hover mode. You will notice that the drone is still drifting down while in hover mode, but you have a stable area that you can land on.
Once you find a flat place and a point where you can hover and your RC drone can follow you instructions, you directions, try applying the directions of the last mode mentioned above and try to have your drone hover in a similar spot while you are applying the altitude hold. directions.
FPV REAL-TIME TRANSMITTION: With the built-in WiFi module, you can see exactly what your camera sees with a live video on your mobile device by installing the APP. HEADLESS MODE - No More Confuse About the Direction : As a Beginner or Kid, you may concern about direction identify (especially non-sensitive about the direction ones), then you can activate headless mode in the beginning of flight, thus no need to distinguish the drone's direction, and you can fly the drone easily. AUTOMATIC ALTITUDE HOLD: Powerful air pressure altitude hold function allows you to release the throttle stick and the drone will keep hovering at the current height. Easy for you to shoot quality images or videos EASY SAFE AND FUN TO PLAY FOR BEGINNERS: Built-in the latest 6-axis flight control systems offer strong stability, easily implement various flight movements, stronger wind resistance; Headless mode eliminates need to adjust aircraft position before flight & improves learning curve. LONG FLIGHT TIME: Includes 3 strong powerful 3.7V 600 mAh LiPo batteries to extend the fun! FAA Registration NOT Required. | aerospace |

Private aviation is such an incredible relief for those conditioned to the absurdity of commercial flight.
Our airport is pretty large, meaning there was someone to talk to on the radio to coordinate our take-off. The pilot took care of that as well, and within a minute we were moving quickly down the runway and generating lift.
Our flight plan was pretty simple. We would fly out to San Francisco, fly around looking at stuff, have lunch at Half-Moon Bay and fly around looking at more stuff.

Air France was forced to scrap 60 percent of its flights as unions estimated three quarters of pilots followed their call to strike.
Unions fear the French airline is seeking to bolster its Transavia France subsidiary, a leisure airline that flies to holiday destinations, because pilots there earn less than Air France pilots.
A pilot for the French flagship carrier earns about €75,000 ($97,000) a year on average while captains of long-haul flights can earn up to €250,000.
In a bid to soothe fears that management is seeking to expand Transavia at the cost of the higher-paid Air France pilots, the company announced the Transavia fleet will be limited to 30 planes instead of the 37 originally planned. This concession, however, will only run until 2019.
The company held talks into the night on Monday with unions that have threatened to strike until September 22 — which would be the longest industrial action at the company since 1998.
There is "not yet" a breakthrough in the crisis but "we are continuing to negotiate," said Air France boss Frederic Gagey.
"We have made proposals. We have recognised the concerns of pilots who thought Transavia France could replace Air France in France," he added.
The plan "is of course not to replace Air France with Transavia," stressed Gagey.
The company plans to "add to the tools at Air France's disposal to attack a new market — the leisure market — by developing Transavia," he explained.
Gagey put the daily losses from the strike at €10 to 15 million.
Despite the strike, the situation at France's main airports was mainly calm as passengers were warned in advance they would be unable to travel.
Terminal 2E at the main Paris airport, Charles De Gaulle, was deserted, with only a few bewildered and stranded passengers who had not received a message in time.
"I was supposed to leave at 9:35. They finally found me a flight in the afternoon," said Delhi-bound Indian tourist Sakhit Dhamija.
The head of the Air France-KLM group, Alexandre de Juniac, told French radio the situation would "improve slightly" on Wednesday, with more than 40 percent of flights in the air.
But the airline later said that it would have to scrap 60 percent of flights on Wednesday.
At certain hubs in France, however, the situation was dire. In the southern city of Toulouse, for example, only one flight out of 43 was to run as scheduled on Tuesday.
And unions warned that the situation would deteriorate the longer the strike went on, as pilots that did fly were forced to take their legally stipulated rest period.
"Tuesday will be even more difficult and on Wednesday, Air France traffic could be halted" completely, said Jean-Louis Barber, head of the SNPL pilots' union.
Fresh negotiations between unions and the management will take place later Tuesday afternoon.
Management already rejected a call by unions to put Air France pilots at the controls of any plane with more than 100 seats, regardless of the operating company — Transavia included.
"The answer is no, because an Air France contract costs more than a Transavia contract," said Gagey.
In neighbouring Germany, a strike planned for Tuesday by flag carrier Lufthansa was narrowly averted after pilot union Cockpit won concessions from management, days after pilots staged an eight-hour walkout over changes to early retirement rules. | aerospace |

7 Feb 2005
WARNING /Disclaimer: Working with turbine jet engines are Very Dangerous, and deals with the handling of highly flammable gasses and liquids, as well as extremely high rotational speeds of the turbine. There is a great fire hazard and a leak could cause catastrophic explosions. Furthermore, the turbine can easily spin out of control and explode, sending lethal shrapnel all over the place. Information here is for educational purposes; project similar to this should only be carried out by professionals.
I have always been interested and fascinated with engines of all types. I remember, when I was young, that I was so fascinated with airplane turbine jets that I walked dangerously close to the engines, only to be stopped by my parents (on those planes where you alight from a bus to walk up a staircase to the plane; not those planes with the walkways from the terminals) I've also been taking apart lawnmowers and studying their engines, and trying to get them started. Of course nothing beats a jet turbine spinning at hundreds of thousands of RPMs. Many consider just the sound of the turbine spooling up to great speeds incomparable to anything else. Since the creation of the first working model of a full-scale aircraft turbojet engine by Frank Whittle and Hans Von Ohain, flight and aviation had been revolutionized. This creation proved to be almost as revolutionary as the Wright brothers’ first flight itself, as planes began to take to the air with higher efficiencies and greater speeds than ever before. Today, we see the descendants of the original jet engine, namely the ramjet, pulsejet, scramjet, turborocket and many more.
However, building a professional turbine is no simple task. Construction of one involves precision making and balancing of the compressor blades, as well as the use of extremely tough and expensive materials. This is well beyond what I could ever do with basic home tools. Nevertheless, with some innovative thinking, some good welding and metalworking skills, the construction of a simple amateur jet engine is actually not complicated.
After the construction of my latest project, the 4" 3kW Tesla Coil 2, it was time to embark on another project. And thus I finally decided to construct a jet engine. Since I had to do a project for my school anyway, I though I might as well do this as my school project. Besides, if my proposal gets approved, I might be granted access to a good metal-working lab and even get some funding! In any case, whether my proposal is accepted, or not, I will be constructing a jet engine.
The page will document the construction as well as testing and improvements of the Jet Engine.
4 Feb 2005
Today was the launch of the Science Mentorship Programme (SMP) at Nanyang Polytechnic. We are placed into the NUS EMP category. (National University of Singapore - Engineering Mentorship Programme)
14 Feb 2005
I discovered a junk shop which had a Turbo Charger! It was a used reconstructed one but it looked in reasonable shape. The blades were however, stuck, but I suspected that it was filled with dirt. I bought it for $45 and lugged it back home. It's a good buy considering that a new turbocharger would at least a thousand dollars, perhaps even more! Due to busy school, I could only do a quick disassembly to find out what happened, and then pop it back on. I guess I'll have to clean it another day. Below are some photos I took.
It's a KKK brand turbo charger. When I opened it up, lots of dirt came out. Now the blades turn a bit better. I seriously need to clean this up but I'll need to find time for that.
I might just use this turbo charger to build my OWN jet engine, separate from the SMP jet engine. As such, I will name this project the GXR-1 jet engine. GXR stands for: Guangyan eXperimental Research 1 - Jet Engine. I'm calling it that because it'll be easier to refer to the project, and besides, it sounds nice. Until next time!
Project Status - Paused indefinitely at the moment due to lack of funds (2005)

Like so many others, Sam Williams had a dream. But unlike so many people, he was willing to put his future on the line to make it come true. Williams left a secure job at Chrysler to pursue his dream of making jet engines smaller and lighter in order to expand their use.
Decades later, the engines he helped develop have helped power craft ranging from jets to missiles.
Williams, who held a bachelor’s degree in mechanical engineering from Purdue University, joined Chrysler in 1942 and quickly established himself as an inventor. Twelve years later -- working with limited finances -- he founded Williams Research Corp. a Michigan-based company, which later became Williams International and pioneered huge advancements in turbine technology and patented a small engine that became the forerunner to those used in modern cruise missiles.
Williams is also remembered for his medical research, including co-founding Second Sight Medical Products, Inc., which developed the world’s first visual prosthetic, known as a “bionic eye,” the National Academies of Science, Engineering and Medicine said in a tribute.
Williams’ work was lauded by three American presidents: Jimmy Carter, who presented him the Collier Trophy; Ronald Reagan, who presented him with the Wright Brothers Memorial Trophy; and Bill Clinton, who presented him with the National Medal of Technology. He received an honorary doctorate from Purdue in 1982.

Cool new digs
for the space station
In 1987, Robert Bigelow founded
Budget Suites of America to give
price-conscious travelers a place to stay.
His latest venture, Bigelow Aerospace,
aims to do the same for people visiting
space. The Las Vegas company,
founded in 1999, makes a module that
can be compressed for transport and
expanded in space. Made from Vectran,
a manufactured fiber spun from polymer, the habitat is cheaper to deploy
than rigid metal structures. In January,
Bigelow landed an $18 million contract
with NASA to add a 13-foot-long,
10-foot-diameter module to the
International Space Station for a two-year test starting in 2015. A linked
group of Bigelow’s larger modules,
such as the BA 330 shown here, could
one day replace the space station.
Plug and play
When expanded, the BA 330
measures 45 feet long and
25 feet in diameter. The habitat
can accommodate up to six
people, who move about
using grab bars.
The habitat has three
exterior panels: one
radiator panel that
releases heat to cool
the interior and
two that generate solar
power for the craft.
Soft, movable cloth walls
allow astronauts to section off
portions of the habitat. The

However in a small proportion of cases aircraft have been destroyed as result of bird strike. In 1988, 35 people died when an Ethiopian Airlines 737 crash landed and caught fire after flying into a flock of speckled pigeons (pdf). The aircraft lost power after birds were sucked into the engines. Authorities believe that bird strike was also the reason US Airways Flight 1549 lost power and ditched in the Hudson River.
Between 1990 and 2007, 79,972 bird strikes were reported to the US Federal Aviation Administration (FAA) (pdf). According to biologist and bird strike expert Richard Dolbeer only around 12 to 15 percent of these strikes result in damage to the aircraft. But in a small proportion of cases, bird strike leads to serious damage and in some cases disaster.
According to Dolbeer and the FAA’s Sandra E Wright (pdf), the most serious bird strike to a civil aircraft occurred in 1960 when a Lockheed Electra taking off from Boston’s Logan Airport flew through a flock of European starlings. One engine shut down and two other engines lost power. Sixty two people died when the aircraft plunged into Boston harbour. Ten people survived.
Researchers say that bird strikes are becoming more common as air traffic increases, bird populations rise and aircraft become quieter. A risk assessment carried out in the late 1990s reported that "in the next 10 years there is about a 25% probability that a large jet transport will be involved in a fatal bird strike related accident in the U.S. or Canada."
Dolbeer argues that it’s important for researchers to be able to identify which species of birds are colliding with aircraft as this data can help biologists create more effective wildlife risk management programs at airports. In a paper for the FAA (pdf) he urged airline staff to send bird feathers, talons, beaks and bones to researchers at the Smithsonian Institution for identification. However he cautioned: "Do not send entire bird carcasses through the mail." | aerospace |

F-22 Raptor Vs Su-30Mki Overview
The Lockheed Martin F-22 Raptor is a single-seat, twin-engine, stealth fifth-generation fighter aircraft that was specially developed for the United States Air Force (USAF). It was made by the partnership among Lockheed Martin Aeronautics,Boeing Defence and Space & security where Lockheed Martin Aeronautics is the prime contractor and made majority of its parts like airframe, weapon system and its final assembly and rest of two are responsible for wings, aft fuselage ,avionics and training system. It took its first flight on 7 September,1997.
Whereas Sukhaoi Su-30MKI is the heavy , all weather , twin finned , long range fighter which introduced in Indian Air force in September 2002.It is the super-manoeurable twinjet air superiority fighter developed by Russia’s Sukhoi and built under icence by Indias Hindustan Aeronautics Limited for the India Air Force.
F-22 Raptor VS Su-30Mki Airframe and Design
F-22 raptor airframe is made from titanium and complex composited . The aft fuselage comprises 67 percent titanium, 22 percent aluminium and 11 percent composite by weight.F-22 makes extensive use of high-strength titanium and composites at 39% and 24% respectively due to withstand with the stresses and heat. The F-22 is highly manoeuverable at both supersonic and subsonic speeds and it is one of the only aircraft that can attain supersonic flights without the use of afterburners.
Wheras The Su-30MKI is a twin engine aircraft. Its airframe is made up of titanium and high-strength aluminium alloys. The fuselage head made of semi-monocoque construction and includes the cockpit, radar compartments and the avionics bay.Su-30Mki aerodynamic configuration is a longitudinal triplane with relaxed stability.The integral aerodynamic configuration combined with thrust vectoring control results in extremely capable maneuverability,taking off and Landing characteristics.
