OAK cameras are light-weight, low-power and performant Spatial AI devices for edge applications, which make them the perfect solution for drone applications, such as:
Precision landing on the target, as demonstrated here by Rishabh Singh. This is possible as object detection runs on the OAK camera at about 30 FPS and has below 150ms delay from camera to the controller.
Emergency landing when your battery is running low. Semantic depth provides 3D location (depth points) of suitable areas to land (eg. grass fields). Stephan Sturges has developed OpenLander repo for this application.
Follow-me drone with the help of 3D object detection and tracking, drone is able to follow you around, as demonstrated here by Rishabh Singh (code here). One could make this solution more robust when combining this with either face recognition or person reidentification AI model.
A few other demos:
Team QuetzalC++ (OpenCV AI comp) - Warehouse inspection with autonomous drones - video
Team QUTEagles (OpenCV AI comp) - Drone-based biosignatures detection system for planetary exploration - video
Augmented Startups built a gesture controlled drone and has 3-part tutorial on YouTube - video
Drone on-device NN-based localization¶
OAK ArduPilot integration¶
Rishabh Singh wrote a few OAK-ArduPilot integration applications like a follow-me app, obstacle avoidance app, and precision landing app. He also wrote 2 blog posts about the integration; Part 1 and Part 2.
Camera vibrations can be a big challenge in applications such as drones, especially if you are using Auto-Focus color camera. To decrease the camera vibrations, we suggest firmly mounting the device on the drone. One could also consider adding shock absorption rubbers (eg. these) to decreate the vibrations. AugmentedStartup has also designed an OAK-1 anti-vibration mount for his drone project:
For drone applications we would also suggest Fixed-Focus color camera, more info here. | aerospace |

Meanwhile, for the first time, scientists have obtained comprehensive information about the inner layers of the planet. The InSight lander of the US space agency NASA has explored the core, mantle and crust of Mars. With the help of earthquake data on Mars, evidence of layers present below the surface have been found 41 miles away. NASA’s InSight lander has been working on Mars since 2018. But after the end of its charge in February this year, the work stopped.
The dust flying on Mars started sitting on the solar panels of the lander, due to which it could not be recharged. The inner layers have been studied by the University of Cologne, the California Institute of Technology and ETH Zurich using data from InSight. Scientists kept taking information from the earthquakes on Mars for two years and kept analyzing the data. For information about the structure of Mars, it was necessary to take information about seismic waves at more than one place on Mars. But InSight is in one place on Mars. So the researchers started analyzing the characteristics of seismic waves that are created when different parts interact.
University of Cologne gave this big information
According to a study by the University of Cologne and NASA’s JPL, the crust beneath the InSight landing site is 12 to 24 miles thick. This is the first time that scientists have extracted information about the size and composition of the Red Planet’s core, its crust and its mantle. For this, the scientists analyzed the seismic waves that had reflected from the interior of the planet, which were caught by InSight’s seismometer.

The system is planned to be launched in 2018, but there is still no infrastructure for getting the newest Lockheed Martin’s satellites in space.
The militaries will collect the proposals until the 17th of November and then will present the specified project to the government. The Air Forces have an unspoken mission to fix a balance between the price and quality of future launching system. Also, they should not forget about the time limits soaring around a practical part of the project that had to be started in 2014.
“We hope to reintroduce competition in order to promote innovation and reduce cost to the taxpayer while maintaining our steadfast laser focus on mission assurance and assured access to space,” said Lt. Gen. Samuel Greaves, Space and Missile Systems Center commander and Air Force Program Executive Officer for Space according to GPSdaily.com.
The newest GPS III satellites will send more powerful civilian signals L2C, L1C and L5 that will be used for “life safety” navigation, among other things. With these −154 dBW, −157 dBW and -160 dBW signals Global Positioning System will get advanced standards of navigation accuracy.

On July 13, the European Space Agency will launch the small CELESTA satellite aboard its Vega-C rocket from a South American spaceport. The satellite will launch a radiation detector that has already worked on the Large Hadron Collider to test its performance in low orbit around the Earth, reports Space.
Physicists at CERN have created their first small satellite, called CELESTA, which expands the work with the Large Hadron Collider into space. The satellite will go to the center of the Earth’s inner radiation belt. This is a region of the Earth’s magnetosphere where high energy charged particles from outer space that have come there are kept. Most protons and electrons.
Using a radiation sensor, which is on board the satellite and which has already been tested at the Large Hadron Collider (LHC), the unit will study the effect of cosmic radiation on electronics. With this launch, CERN wants to expand its work in radiation and basic physics to outer space.
According to European researchers, the radiation sensors will help the CELESTA satellite test the possibility of using this technology during space missions, in particular in radiation-sensitive satellites.
The Vega-C rocket is a light four-stage launch vehicle that can simultaneously carry up to 12 small satellites on board. This will be the first launch of the updated Vega family rocket, which in addition to the CELESTA satellite will carry the Italian LARES-2 satellite and 5 other smaller scientific satellites. In the case of the LARES-2 satellite, its task is to try to confirm aspects of Einstein’s general theory of relativity during space travel.
As already written Focus Recently, researchers at the Large Hadron Collider made another important discovery. Physicists have been able to discover a new way of combining quarks – the most important elementary particles for the structure of the universe.
In addition, physicists at the Large Hadron Collider set another record. As already written Focus, the particle accelerator can now compress protons with unsurpassed energy levels. Researchers have managed to achieve more than 1.5 billion collisions per second.
We remind you that some researchers believe that plans to build a more powerful particle accelerator are a waste of a huge amount of money. Where do scientists suggest that these funds be sent to make new discoveries in physics, Focus already written. | aerospace |

Aptima training scientist Samantha Emerson said: “The learnability study will help us not only understand the baseline pilot skills and competencies needed for proficient eVTOL flight, but also the impact of automation on pilot performance.
“Both experienced and novice pilots bring unique skills and capabilities based on their experience, so we assess how these differences affect performance in aircraft with varying levels of automation.”
In more automated platforms, where pilots mostly control flight settings rather than the aircraft itself, preliminary research suggests experienced pilots tend to have more difficulty adjusting to automation than novice pilots.
Emerson continued: “This is why we will look to see if experienced pilots tend to ‘overcontrol’ of the aircraft, and even though a more experienced pilot may possess greater ability in controlling aircraft, not all those skills may be useful or even desired.
“In platforms with more automation and augmentation, it may require ‘unlearning’ and re-training of behaviours to prevent interference or conflict with automated operations.”
Aptima, a leader in human-machine teaming and training, will help evaluate how automation affects pilots in different eVTOLs, which existing skills will be transferable, and what new skills will require training.
To assess pilot learning and performance, Aptima will use technologies and techniques developed with the Air Force Research Laboratory over the past 15 years to measure, analyse, understand, and optimise Airman performance.
The Performance Evaluation Training System (PETS) harvests data from simulators to provide objective, system-based measures, and Aptima’s Spotlite handheld tool is used by subject matter experts to provide observer-based measures of performance.
In March, the US Air Force awarded Electra a Small Business Technology Transfer contract in partnership with the Massachusetts Institute of Technology (MIT), to advance the development of flight control systems for Electra’s hybrid eSTOL aircraft.
Also in March, two US Air Force pilots flew BETA Technologies’ ALIA eVTOL aircraft in what was claimed to be the first-ever manned demonstration flight with an Agility Prime partner. | aerospace |

It's official: There's water ice on the moon, and lots of it. When melted, the water could potentially be used to drink or to extract hydrogen for rocket fuel.
NASA's LCROSS probe discovered beds of water ice at the lunar south pole when it impacted the moon last month, mission scientists announced today. The findings confirm suspicions announced previously, and in a big way.
"Indeed, yes, we found water. And we didn't find just a little bit, we found a significant amount," Anthony Colaprete, LCROSS project scientist and principal investigator from NASA's Ames Research Center at Moffett Field, Calif.

The flight was conducted in Yuma, Arizona, and demonstrated Redkite’s interoperability with different platforms, Logos Technologies said.
“We’ve had Redkite on planes and helicopters, and just recently we tested an integrated version of the WAMI sensor inside the payload bay of a Group 3 unmanned aircraft system (UAS),” said John Marion, president of Logos Technologies. “Now we’ve integrated a Redkite pod to the underside of a TigerShark wing.”
During the demonstration with TigerShark, sensor operators used Redkite to collect real-time wide-area motion imagery, geo-register it, and stream it down to the tablets held by mobile users on the ground.
Marion says that, during the demonstration, operators on the ground got the imagery on their mobile devices without any problems. “The test went exceptionally well,” he said. “We showed that Redkite is ready to go on TigerShark as well as any other similarly sized platform.” | aerospace |

Like the 7X, the Digital Flight Control System (DFCS) in the 6X provides flight envelope protection to avoid inadvertently exceeding structural speed limits and stalls. Because of these protections, pilots can command maximum performance quickly and decisively without exceeding tolerances. Hazardous situations such as wind sheer, sudden traffic avoidance maneuvers and traffic pattern go-arounds become far easier and safer to manage.
Hand flying a Falcon equipped with a DFCS imposes a much smaller workload on the pilot. For example, the system automatically trims the aircraft; no pilot action is required. Non fly-by-wire aircraft, and even some aircraft with fly-by-wire, require frequent manual trim adjustment when hand flying, adding to pilot workload.
Every curve has a purpose
The Falcon 6X is the beautiful marriage of a wide-body cabin with an all-new, fast and ultra-efficient wing. The 6X wing has a moderately swept leading edge (33 degrees) and an innovative curved trailing edge. Its winglets are unique, designed to perfectly integrate with the wing. Constant and subtle wing contour changes control airflow at high speeds.
The result is the highest lift/drag ratio of any Falcon wing, a key for improving fuel efficiency. The 6X wing has high buffet margins at high altitude and high cruise speeds, improving speed and safety.
Today's engine meets tomorrow's requirements
The Falcon 6X and the Silvercrest engine were developed in tandem, with Safran’s Snecma propulsion division designing the engine to Dassault’s unique requirements. The aerodynamic refinements of the 6X, paired with the Silvercrest engine, yield remarkable performance and efficiency.
Its robust design draws on Snecma’s decades of experience with the most widely used airliner engine, the CFM56. The Silvercrest engine’s advanced aerodynamics, metallurgy and computer controls make it the most efficient and powerful engine for its size.
The flight deck - The pilot's office
Pilots of modern Falcons will quickly be at home on the 6X flight deck, with its intuitive EASy avionics architecture. The 6X will be equipped with 3rd generation EASy, a future derivative of Dassault's Award Winning avionics suite. The flight deck is bigger and more comfortable. Its design reflects input and requests from current Falcon operators — for example, increased automation to more rapidly power up and power down the aircraft.
Four large windows provide exceptional visibility, including wide-angle visibility to check wingtip clearance while taxiing. The glare shield is even shaped to give pilots an expanded field of view.
Crew seats are larger and more comfortable, with more legroom. Seats are easily aligned for a perfect visual perspective. Pilots of any size will feel they are sitting in the perfect position.
Your support network
The Falcon 6X establishes a new benchmark for on-board maintenance monitoring capability. Where previous Falcons have onboard diagnostics to monitor hundreds of parameters, the 6X system connects to all onboard computers and monitors approximately 10,000, all in real-time.
The 6X is the first Falcon to incorporate a real-time maintenance monitoring system, which constantly transmits maintenance status to Dassault Customer Service on the ground. Flight departments are immediately notified of an in-flight maintenance issue so that ground support can be put into motion quickly, even before the plane has landed. Moreover, this new data collection system permits fleet-wide trend analysis to further improve reliability.
Peace of mind with SilverCare: the Silvercrest service
Robust design allows for on-condition (rather than periodic) inspection. On-condition maintenance is common on commercial airliners, but the Silvercrest engine is the first business aviation engine without required overhaul intervals. Because maintenance is “on-condition,” operators may never have occasion to remove an engine for overhaul.
The Silvercrest SilverCare service plan makes engine support costs entirely predictable and enhances resale value.
Snecma today supports more than 25,000 commercial engines around the world, including more than 100 airliner aircraft operated as business jets, through existing field infrastructure and technical support.
A dedicated worldwide support network, separate from airline support operations, will support Silvercrest operators. | aerospace |

At its closest point, the spacecraft will be closer to the Sun than any previous spacecraft, braving the fierce heat and will carry its telescopes to almost one-fifth of Earth’s distance from our nearest star. It will provide unique data and imagery of the Sun.
Solar Orbiter will be the first satellite to provide close-up views of the Sun’s polar regions, which are very difficult to see from Earth, providing images from latitudes higher than 30 degrees. It will be able to tune to the Sun’s rotation around its axis for several days, and so it will be able for the first time to see solar storms building up over an extended period from the same viewpoint. It will also deliver data of the side of the Sun not visible from Earth.
At nearly one-fifth of Earth’s distance from the Sun, Solar Orbiter will be exposed to sunlight 20 times more intense than what we feel on Earth. The spacecraft must also endure powerful bursts of atomic particles from explosions in the solar atmosphere.
To withstand the harsh environment and extreme temperatures, Solar Orbiter must be well equipped. It will exploit new technologies being developed by ESA for the mission BepiColombo to Mercury, the planet closest to the Sun. This includes high-temperature solar arrays and a high-temperature high-gain antenna.
When travelling at its fastest along its orbit around the Sun, Solar Orbiter will be able to remain positioned over approximately the same region of the solar atmosphere, as the Sun rotates on its axis. It will be the first time in the history of solar exploration that this will be achieved by a solar spacecraft. Just as geostationary weather and telecommunications satellites are stationed over particular spots above Earth’s surface, so the spacecraft will seem to ‘hover’ for a while over the Sun. Solar Orbiter will therefore be able to watch storms building up in the atmosphere over several days.
Solar Orbiter is specially designed to always point to the Sun, and so, its Sun-facing side is protected by a sunshield. The spacecraft will also be kept cool by the positioning of special radiators, which will dissipate excess heat into space. The solar arrays and the communications system are inherited from the design of ESA’s BepiColombo mission to Mercury.
Following launch, currently foreseen for 2015, Solar Orbiter will begin its journey to the Sun. This will require a cruise phase lasting approximately 3.4 years. During this time, the instruments will be commissioned, and some in-situ data will be acquired. During the cruise, Solar Orbiter will use gravity assists from Venus and the Earth. These swing-bys will put Solar Orbiter into a 150-day-long orbit around the Sun from which the spacecraft will begin its scientific mission. | aerospace |

(If you happen to have $200K lying around, then start planning your trip now!) But you can explore the history of space travel here on earth. The display of NASA’s space shuttle Enterprise opened last week at Intrepid Sea, Air and Space Museum in New York City.
In the Intrepid Museum’s Space Shuttle Pavilion, Enterprise — NASA’s very first space shuttle — is elevated 10 feet off the ground, so you can walk directly underneath it. An elevated viewing platform also allows you to get a better look. Intrepid Museum is one of the few places in the world to offer an up-close view of a space shuttle.
Or, if you happen to be in Florida, the Kennedy Space Center opened its doors this week to the public. For the first time in its 50-year history, visitors can now venture almost a quarter-mile inside the security fence and get a look at Launch Pad 39-A — the starting point for all 6 Apollo missions that landed on the moon.
For a limited time, the tours will include trips to KSC’s 52-story Vehicle Assembly Building and the Launch Control Center — all as part of the center’s 50th anniversary celebration.
Go back to those days of childhood wonder when you pondered what was out beyond the stars by visiting one of these touchstones of the United States’ history of space exploration.

First female commander of the International Space Station; veteran of six space walks and set records among American astronauts for spending the most time in space
Peggy Whitson was born in 1960 in rural Mount Ayr, Iowa where her dad was a farmer. In her own words: "As a child, I saw a lot more hogs growing up than I saw people. The closest town had only 32 people living in it, so my high school was consolidated for the whole county. We had around 300 students in my high school, so it was a very small environment that I grew up in."
Encouraged by her parents who often reminded her that she could do whatever she set her mind on, Peggy expressed an early interest in science and space flight. After high school, she entered the small college of Iowa Wesleyan in Mount Pleasant, from which she graduated in three years in the double major of biology and chemistry before going on to graduate school at Rice University in Houston, Texas. There, she earned her Ph.D. In biochemistry.
She soon began working at Johnson Space Center in Houston, Texas, as a National Research Council Resident Research Associate. From 1992 to 1995, she served as project scientist for the Shuttle-Mir Program and, until her selection as an astronaut candidate in 1996.
In the interim, she was also an Adjunct Assistant Professor in the Department of Internal Medicine, and Department of Human Biological Chemistry and Genetics at the University of Texas Medical Branch in Galveston, Texas, and in 1997, she began a position as Adjunct Assistant Professor at Rice University in the Maybee Laboratory for Biochemical and Genetic Engineering.
Why She's Important: NASA astronaut and research biochemist Peggy Whitson, as a result of her two long-duration missions (of a total of 376 days) to the International Space, became NASA's most experienced astronaut. And her total of six career space walks and their combined duration of 39 hours and 46 minutes were records for a female astronaut, and places her 20th among all space flyers in this category.
In her second mission to the International Space Station in October 2007 with Expedition 16, she served as the first female commander of the ISS. As commander, Peggy supervised and directed a significant expansion of the living and working space on the ISS, including the installation of components made by European, Japanese, and Canadian space agencies. During this six-month mission she also performed five space walks to carry out maintenance and assembly tasks.
After spending nearly 192 days in space during her historic mission, Peggy returned to Earth aboard Soyuz TMA-11 on April 19, 2008. The crew of Soyuz TMA-11 had a difficult and dangerous ride back to Earth; the Soyuz's equipment module failed to separate properly from the reentry module, and so the craft followed an unusually steep descent trajectory – a "ballistic" descent at eight times the force of Earth-normal gravity. The crew made an extremely hard landing, which missed the target by 470 km (300 miles). Fortunately, Peggy and other crew members suffered no permanent injuries.
Other Achievements: She currently serves as Chief of the Astronaut Office at NASA, overseeing all NASA astronaut activities, including crew selection and training.
In Her Own Words: When asked if she ever realized growing up on her farm in Iowa that she would one day set a record for time spent in space, Peggy replied: "No, I don't think I was perceptive enough to know that then. There is so much involved in these things, including just being in the right place at the right time. I can't really say I've taken credit for any of that. But I'm happy to have been able to play that role. I think the important part of that role is encouraging other women to break that record." | aerospace |

Posted By Kat Plewa on Apr 3, 2019 | 0 comments
NASA has been a pioneer not only in space travel, sending the first man ever to the moon, but also in utilizing Additive Manufacturing for aerospace applications. 3D printing allowed them to break new boundaries and improve their rockets. Let’s have a look at the history of NASA 3D printing and what are the future prospects.
Why is NASA 3D printing?
The aeronautics agency has to keep up with the latest innovations and constantly look for improvements in their rocket designs. The answer over the last years has been Additive Manufacturing. This technology provides NASA with numerous benefits.
What is one of the most important parts of any rocket design? Weight. 3D printing is just the perfect solution to this. 3D printed parts can be redesigned with lattices, which can bring the weight dramatically down. This is a crucial aspect of building rockets.
AM also allows for fast production. Prototyping with 3D printing lets researchers adjust the design accordingly, which is cost and time efficient. The perfect prototype can easily become the end product, all that needs to be done is for the 3D model to be sent to print in the final technology.
NASA is 3D printing high-quality mechanical parts, resistant to temperatures as high 3300°C (6000°F) and even as complex as for a rocket. Rocket parts have to be perfect. Even the smallest mistake can compromise the whole mission and result in absolute disaster. NASA trusts Additive Manufacturing technologies to rise up to the highest standards.
NASA 3D printing history
The first news about NASA 3D printing is back from 2013 when they asked themselves: ‘’What can survive blazing temperatures of almost 6,000°F without melting? What did not break apart at extreme pressures? What is made by a new process that forms a complex part in just one piece? What takes less than three weeks to go from manufacturing to testing? What can reduce the costs of expensive rocket parts by 60 percent or more?’’
The answer was Additive Manufacturing. NASA confirmed that testing 3D printed parts resulted in showing no difference between them and traditionally manufactured ones. Sandra Elam Greene, the propulsion engineer supervising the tests, studied the results said: “Two separate 3-D printed injectors operated beautifully during all hot-fire tests.”
3D printing gave NASA durable, heat resistant and complex parts. On top of that, it reduced costs by over 50%, from 10 000$ per part to less than 5 000$. Production was also more time efficient and took about 40 hours to manufacture.
Carrying on with 3D printed engine
NASA didn’t stop with just one 3D printed engine part. By 2015 they have developed multiple engine components and tested them together. They produced 20 000 pounds of thrust! Elizabeth Robertson, the 3D printed engine manager, commented: “We manufactured and then tested about 75 percent of the parts needed to build a 3-D printed rocket engine. By testing the turbopumps, injectors, and valves together, we’ve shown that it would be possible to build a 3D printed engine for multiple purposes such as landers, in-space propulsion or rocket engine upper stages.”
3D printing in space
The rocket is launched and made it safely out of orbit- that’s great. But what if something goes wrong then? We can’t just send new parts to space and rockets are already packed full of spare parts, which are heavy and very often remain unused, which is just a waste of money.
This is where 3D technologies come to the rescue. Broken parts? Missing some screws? 3D print them in space! Made in Space, in cooperation with NASA, developed zero gravity Additive Manufacturing and gives astronauts new possibilities. This can revolutionize space travel and enable new possibilities.
Can we use AM.. on Mars?
We dedicated a whole blog post to this subject, but it’s definitely an important part of NASA’s 3D printing history. They launched a habitats challenge for the best ideas to colonize Mars.
The best idea was to send 3D printers which prepare everything for people to arrive. This solution means full automatization and independent manufacturing on a different planet! Additive Manufacturing allows for the use of new materials and development solutions adjusted accordingly to the environment. This means the highest customization possible.
Meanwhile on earth
The latest news from NASA is a using copper-based alloy for 3D printing rocket propulsion components. The newly developed copper alloy is especially attractive for NASA because it is a strong and highly conductive material. They already 3D printed combustion chamber liners and fuel injector faceplates with it.
This alloy meets the highest aerospace-grade standards. Tests done by NASA proved that the material performs better at 50% thicker layers (0.045 mm), which allowed for faster cooling and sped up the production time. The parts were then run through a hot isostatic press to reduce the porosity of the metal, and finally they were sent for post-processing and room temperature tensile testing.
The 3D printed parts with copper alloy performed excellent thermal conductivity, great deformation resistance, and strength at high temperatures. This can truly change the future of space travel as we will be able to 3D print rocket engine parts faster, cheaper and they will be lighter, which reduces the use of fuel.
Is it time to pay more attention to metal 3D printing?
Yes! As you can see, NASA has only been using 3D printing for over 6 years and they have made some huge breakthroughs. Their 3D printed metal engine parts can withstand temperatures over 3 000°C and a great amount of stress produced during launch. We even started 3D printing in space! Additive Manufacturing is much more than simple FDM printers. It is the technology of the future.
But don’t think that only giants such as NASA can use AM. With online 3D printing services, you can start improving your production with metal 3D printing today! It is as easy as uploading your 3D model or contacting our sales team if you have any questions.

November 01 2010 12:38 PM
A Northern Ireland computer scientist is helping to revolutionise American space exploration.
Roy Sterritt is using automatic computing to make craft self-controlled, instead of mission control having to guide them at practically every turn. Swarms of small spaceships would replace single crafts.
Mr Sterritt and NASA scientist Mike Hinchey have collaborated on the projects and US authorities granted the space agency two patents on the men's work.
The Jordanstown researcher was recently honoured for his pioneering work by NASA in Maryland. "It was a marvellous feeling to be recognised publicly at such a high-profile event," he said.
"NASA's recognition adds a whole new dimension to my activity at Ulster which I hope will develop further and lead to other innovative work that will make space exploration more secure."
He and Mr Hinchey devised programs that could make small robotic craft self-directing, self-controlling and self-destructing if their autonomous behaviour threatened the safety or aims of the mission.
Each received a Nasa Patent Application Award and a patent plaque at the prestigious annual Nasa Goddard Space Flight Center's new technology report program ceremony in Mitchellville, Maryland, last week.
The Belfast man first caught Nasa's attention six years ago when senior scientists there heard him speak about his innovative concepts.
Mr Sterritt lectures in informatics at the University of Ulster's School of Computing and Mathematics and is a member of the Computer Science Research Institute. His interest in space related work was triggered partly by science fiction books as a child and films like Star Wars.

Drones, officially called an Unmanned Aircraft System or a “UAS”, came onto the scene a few years ago rather quickly. You can purchase a drone online or in a store for as low as $49.99 or spend thousands of dollars with sophisticated added capabilities ranging from cameras to high definition live video. What you may not know is that there are rules, regulations and legislation being implemented just as fast as the newest drone models hits the market.
According to the Federal Aviation Administration’s (FAA) Safety Briefing (May/June 2017), the following are guidelines that an owner of a UAS needs to adhere to even if you are flying your drone as a hobbyist:
Last year, the FAA released its Small Unmanned Aircraft System (sUAS) regulations with the new Title 14 Code of Federal Regulations (14 CFR) part 107. New owners of a drone should check the website at www.faa.gov/uas before launch. This will educate drone operators on whether they need a Remote Pilot certificate or not.
For the legislative cycle that ended September 15, 2017, there was one additional drone-related bill passed by the legislature. AB 527 (Caballero) will make modest revisions to existing law regarding licensure requirements for those who operate pest control aircraft. If Governor Brown signs AB 527 by October 15, any person operating an unmanned aircraft for pest control will need to be certified to do so by the California Department of Health. It will require additional training and expertise than is currently mandated.
If you are using a drone for pleasure or business-related activities, make sure you follow all UAS requirements to avoid fines and penalties that can add up to more than the cost of the new toy. | aerospace |

Due to the movement of the satellite along a spiral trajectory, the angle between the vectors of the gravitational force and the orbital velocity turns out to be less than 90 °. As a result of this, the gravitational force does a positive job and, according to the kinetic energy theorem, leads to an increase in the orbital flight speed. The essence of this phenomenon is called the aerodynamic paradox.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position. | aerospace |

(KSNW) — Within a matter of months, drones may be delivering medical items to and from the hospital in Hutchinson.
Air Methods, an air medical service provider, has launched Spright, a drone program designed to help with supply challenges in the healthcare industry. Spright is kicking off the project by partnering with Hutchinson Regional Medical Center (HRMC) and using Wingcopter delivery drones.
But before the drones can actually carry medical supplies, medicines, or lab samples, they will be put through feasibility flights from the hospital.
Chuck Welch, chief business development officer at HRMC, says the drones will need to demonstrate that they can operate completely unmanned using GPS and cell towers. He says Hutchinson was chosen for this pilot project because of the wide, open space around the town.
Welch says the items will start small, such as a piece of paper, but once the program is up and running, the drones will be able to carry approximately 13 pounds of items.
The drone that will be used, the Wingcopter 198, can travel 68 miles on a single battery charge and at a speed up to 89 miles an hour, depending on conditions.
If all goes well, Spright plans to get a fleet of 100 of the drones to deploy across the U.S. It says hospitals will not need specialized landing pads and will fly low enough that they do not interfere with planes and helicopters. | aerospace |

Barnes, Laurie Eugene, 1stLt. USMCR
Bosbery, Donald Charles, 1stLt. USMCR
Meeks, Charles Henry III, Sgt. USMC
Barnhart, Beverly Lee, SSgt. USMC
On 11 April 1969, YK-16 was the second aircraft in a flight of two conducting resupply missions. The accident resulted from the failure of one of the three forward rotor blades due to metal fatigue. When the one blade failed it produced enormous unbalanced load conditions on the forward rotor head and forward transmission causing them to be literally torn from the aircraft. During this disintegration process, some of the debris impacted the aft rotor system and pylon and it too was torn from the helicopter resulting in the catastrophic crash.
The aft pylon and the main potion of the fuselage, with is contents, fell to earth in the same general location and were retrieved by recovery forces of the squadron in short order. The forward transmission and rotor head assembly were located a couple of days latter by a Grunt patrol. The squadron requested that EOD (Explosive Ordnance Demolition) experts be sent to "check out" the site for booby traps before the squadron recovery personnel were sent in to retrieve the final portions of the CH-46. Recovery of the forward rotor head and transmission would be instrumental in determining why the failures had occurred. Somehow this message got slightly garbled as it made its way to III MAF and then back down to a young Marine Corporal on Hill 37. The Corporal did as he was instructed. He went out to the site of the forward transmission and rotor head, and made sure it wasn't booby trapped by putting 30 pounds of C-4 on the assembly and setting it off. Needless to say, it didn't look like a transmission and rotor head assembly by the time it got back to the squadron and of little value to the Squadron Safety Officer, 1stLt. Larry "Slick" Britton, who was conducting the aircraft crash investigation. The Corporal from Hill 37 was brought to Marble Mountain so he could see an intact assembly. He was queried as to the differences between the one at Marble Mountain and the one he "d-booby trapped".
Lt.Col. Bianchino remembers, "The entire crew were splendid Marines. Lt. Barnes had recently been designated an aircraft commander and Lt. Bosbery was soon to have been designated one also. Sgt. Meeks was respected for his functions within the Operations section and SSgt. Barnhart for his years of service to the Corps and knowledge within the Maintenance Section of the squadron".
Lt.Col. Larry "Slick" Britton recalls, "In 1970 or 1971 a squadron at New River, North Carolina lost a CH-46 at Bogue Field, also due to a blade failure very similar to "Stash" Barnes' accident. After this accident, Boeing Vertol (manufacturer of the CH-46) told the Navy they weren't going to make of fix any more steel blades since they had developed a fiberglass blade that was far superior. Boeing had developed and proven this new fiberglass blade some three years prior but the Navy wouldn't buy it because it's cost was approximately three times that of a steel blade. Because of Boeing Vertol's 'gutsy' move, the '46 fleet was equipped with the fiberglass blades. I wonder how the budget weenie who 'saved' the Navy money by not agreeing to buy the fiberglass blades feels about his frugality?" I wholly agree with Rich Bianchino's sentiments that the entire crew were 'splendid Marines'. I would only add that, with the exception of a very few, all the Marines I had the good fortune to serve with were splendid Marines.

As a tribute to the games, they decided to join in on the fun in the name of sportsmanship and created their own Space Olympics. To add to the gravity of the situation, the crew even went on to award Olympic medals to the winners.
For the space games, the crew split into two cohesive teams: the Soyuz team and the CrewDragon team. They are all pretty fit, as the ISS crew does two-and-a-half hours of exercise a day. But what would be the sports of Space Olympics?
Without gravity or much (interior) space, the crew had to come up with original ideas. Obviously, the 100m sprint was out of the question and swimming or diving were impossible.
So, the events ranged from synchronized floating or lack-of-floor routine to (very) long jumps and no-hand ball. To make things more authentic, the team even hung mini flags of all the countries in the world to the roof of the ISS lab.
It's further proof, if any were needed, that the Olympic Games can inspire anyone, anywhere. | aerospace |

HAMUEL HSC-turning-milling center of the HSTM SERIES
Hybrid Turbine Blade & Turbo Fan Remanufacturing Machine
50% 3D Laser Cladding Machine
50% Milling Machine with 3D Scanning
= 100% Automated & Adaptive Repair Solution for High Value Components
Hamuel’s Hybrid machining options allow full adaptive processes that can combine high speed milling, 3D scanning, laser cladding, 3D inspection, deburring / polishing, and laser marking, all in a single machine.
Laser powder cladding is becoming prominent in the machining industry, not only to produce new complex parts which are not possible by conventional manufacturing processes, but also to repair damaged parts. Turbine Wheels with damaged blades, for example, are normally rejected due to the high repair cost.
Using the laser cladding process, the damaged blade profile can be reformed back to the original equipment specifications. The Hybrid system would do this by milling off the damaged area and then building the material back up by laser cladding, without removing the part from the machine between operations, resulting in a decisive cost advantage.
Laser cladding can also combine different materials together allowing the composition and topology of parts to be optimized for long lasting performance in harsh or extreme operating conditions. Test parts show an excellent quality of the welding area that fulfills the stringent requirements for aerospace parts. Like all other tools, the laser cladding head is stored in the tool magazine with the same standard interface HSK A63, allowing the adding of material to be easily integrated into the part process, along with complete machining in a single clamping operation.
The 150 HD Hybrid, along with every Hybrid system, includes adaptive processing through in-cycle reverse engineering and 3D laser cladding (or Additive Manufacturing), without compromising the milling quality that Hamuel is known for. The ability to extend the life of high value and complex components made from specialized materials, is both cost effective and environmentally friendly.
The Hybrid manufacturing machine system combines the capabilities of five different machines: 5-axis CNC milling, Laser Cladding Cell, Robot Polishing Cell, CMM and Laser Marking. This combination in a single machine, saves floor space and costs only a fraction of a multi-machine repair cell. It’s the most flexible system for re-manufacturing worn parts and consumes only a fraction of the energy, time and cost required to manufacture new parts.

Ornithopters, especially those that resemble birds, benefit greatly from having the ardupilot system on-board, as this way they can be set to “patrol an area”, and thus scare off “flying pests” such as pigeons, … (these damage freshly sown fields by eating the seeds planted, also eat fruit such as currants, blueberries, … )
Ready-to-fly (RTF) ornithopters are not obtainable. Ornithopters can be build, however, using the ornithopter kits from BirdKit. There are some designs (i.e. Kestrel), you can also print the airframe and wing flapping mechanism using a 3D-printer. Kazuhiko provides such 3D-printable files from the Kazuhiko Kakuta Shapeway shop. The 3D-printable parts need to be combined with the fuselage of other kits (more is explained on this image, this excel file, and these youtube video’s.
You can also try to build an ornithopter from scratch. Ornithopter.org has info on how to do this. There’s also an ornithopter gearbox for sale by Birdkit, and some ornithopter gearboxes can also be found at shapeways.
At least two ornithopters (GosHawk25iV made by Kazuhiko, and Robird by Clear Flight Solutions) are known to work with an ardupilot autopilot. The GosHawk25iV, and the proprietary Robird, so in theory, many ornithopters could be made to work with it.
Autopilot Setup Differences¶
Fixed wing aircraft generally use 4 control ouputs: aileron, elevator, throttle and rudder.
In Orinthopters, these primary controls are:
For the wings, they can be built using 3D-printed wing spars (or profiles that fit around a carbon spar. The airfoil profile can be any cambered profile depending on the ornithopter design, and the exact airfoil is usually calculated. The angle of attack is often about 15 degrees. | aerospace |

According to the airline, flight operations will commence from August 20.
Civil Aviation Minister Suresh Prabhu in a series of tweets said that due to disruption of flights from Kochi Airport, a joint team sent by the Ministry approved to commence scheduled flights by Alliance Air ATRs between Bangalore and Kochi naval air base.
Prabhu further said that more destinations, including Madurai, will be added soon and that other airlines are also likely to join the effort.
"In view of disruption of flights from Cochin airport due to floods, a joint team sent by @MoCA_GoI has approved starting of scheduled commercial flights using ATRs by Alliance Air, a subsidiary of Air India, between Bangalore and Cochin Naval Air base.
#KeralaFloods," the Minister tweeted.
"The flight operations between Bangalore and Cochin Naval air base will be starting from 20th August morning.
More destinations such as Coimbatore, Madurai are also in the pipeline. Other airlines are likely to join this effort too. All possible steps are being taken #KeralaFloods."
Earlier in the day, Alliance Air operated a proving flight to the Kochi naval base.
"As an exemplary initiative to fly out stranded people, AI's subsidiary Alliance Air operated a non-commercial proving flight on an ATR (turboprop) to Kochi's naval base with a team of DGCA, AAI and flight safety officials," Air India said in a statement.
"This whole exercise is aimed at confirming the feasibility of having Alliance Air operate more flights to Kochi's defence airbase with turboprops to evacuate passengers."
The development comes as the state reels under torrential rains and the worst floods the state witnessed.
The grim situation has left the state with only two operational civil airports at Thiruvananthapuram and Calicut, as operations at Kochi airport have been suspended till August 26 on account of rising water levels in the operational area.
The civil airport in Kochi is severely flooded and stands closed till August 26. | aerospace |

Galactic 02 will launch from Spaceport America in New Mexico at 9:00 a.m. MST (11:00 a.m. EST), which will be livestreamed.
The spaceflight company, founded by British businessman Richard Branson, will have six people on board, with three of them being regular civilians.
The mission will also make history with the first Olympian in space as well as the first Caribbean astronauts and the first mother-daughter duo in space.
Onboard is Jon Goodwin, 80, who competed in the 1972 Munich Games as a canoeist. Goodwin has Parkinson’s and will be the second person with the disease to go to space.
“For me to go to space and defy Parkinson’s is hopefully inspirational to all people,” he said in a promotional video published two weeks ago.
The ship, VSS Unity, will also carry Keisha Schahaff, 46, and Anastatia Mayers, 18, a mother-daughter duo from the Caribbean. They won their seats in a drawing raising funds for the nonprofit Space for Humanity.
Mayers is a college student studying philosophy and physics at the University of Aberdeen in Scotland and will become the second-youngest person to travel to space.
The company says its goal is to take paying customers to the edge of space, in a similar vein to Jeff Bezos’s company Blue Origin.
Flying with them will be Beth Moses, chief astronaut instructor at Virgin Galactic, to measure the inflight experience. VSS Unity will be piloted by commander CJ Sturckow and pilot Kelly Latimer.
Meanwhile, VMS Eve, which is the “mothership” carrier for VSS Unity, will be piloted by commander Nicola Pecile and pilot Mike Masucci.
In 2021, Virgin Galactic received approval from the U.S. government to take customers on spaceflights.
Galactic 01, the company’s first mission, carried four passengers, all from Italy, on its suborbital flight, about 50 miles above Earth. They included two members of the Italian Air Force, an engineer with the National Research Council of Italy and an astronaut with Virgin Galactic.
The crew conducted 13 experiments including measuring cosmic radiation and thermo-fluid dynamics including whether certain liquids transform into gases at high altitudes.
Other experiments were related to human vitals — examining how circadian rhythms are affected by microgravity, studying any changes in the cells that line blood vessels and comparing heart and skill MRIs before and after the flight.

MARTINSBURG, W.Va. (Aug 29, 2022) – Forty-nine Civil Air Patrol (CAP) members from three different states flew on a Boeing C-17 Globemaster III aircraft courtesy of the 167th Airlift Wing, West Virginia Air National Guard on August 25, 2022.
All members processed through metal detectors and then proceeded to a passenger waiting area where they watched a history video about the wing. Colonel Bill Annie, 167th Mission Support Group commander, met with the group sharing about his Air Force career and his original roots in ROTC.
The orientation flight departed from the base and flew down the Shenandoah Valley to Staunton before looping back around to Martinsburg. Cadets were permitted to walk around the aircraft and also sat briefly in the cockpit and chatted with the pilots during the flight. A select few cadets also experienced the take off and landings from the cockpit. After landing, the group enjoyed lunch in the dining facility and then visited with airmen from different career fields across the base share about their experiences and careers in the Air National Guard.
The activity was a great experience for the cadets that attended. Many flew on a C-17 for the first time and/or experienced flight on a military aircraft and will be treasuring this as a life-long memory.
Cadet Staff Sergeant Jude Patterson, from the Winchester Composite Squadron, commented, “The C-17 flight was an extraordinary, once in a lifetime opportunity, which provided a fun experience for myself and my fellow cadets.”

by David Webb, chair of UK CND and convenor of the Global Network Against Weapons and Nuclear Power in Space
· Boris Johnson’s recent announcement of a £16.5billion boost to the UK’s defence budget, at the expense of the foreign aid contribution, will do nothing to keep us safe and will take resources that could help ease the strain on the NHS at this critical time.
However, it will be music to the ears of aerospace corporations as, together with the current 0.5 per cent above inflation annual increase, it means an overall increase of about £24.1billion in defence spending over four years—the biggest increase since the start of the Cold War.
Billions have been promised for technologies that will “revolutionise warfare” and plans include the establishment of a new agency dedicated to AI, a National Cyber Force and a Space Command which will launch its first rocket from Scotland by 2022.
A UK Space Command has been on the agenda for a while and follows the 2019 commitment of £30 million to fast-track the launch of a small satellite demonstrator.
Apparently it will “work alongside MOD’s recently formed Space Directorate as a joint command structure” and is needed because the space domain is “critical” to the UK remaining a “leading 21st century power”.
Space, Covid and Brexit
Space is also being viewed as a path to recovery from the economic havoc wreaked by Covid-19 and Brexit. Dr Colin Baldwin, Head of Local Growth Strategy at the UK Space Agency has said:
“We know that space will help put fuel back in the tank of the economy as it recovers from the pandemic and are determined this growth will be felt in all corners of the country.”
According to the UK Space Agency, space is one of “the UK’s fastest growing and most venerable sectors” and has trebled in size since 2010, at the last count the UK space industry employs around 42,000 people and generates an income of nearly £15billion every year.
The global space market is expected to treble in the next 10 years and the UK government wants in. It is funding a number of regional ‘space hubs’, led by a consortium of Local Enterprise Partnerships (LEPs) to bring together local authorities, academic institutions, research groups and businesses to ensure that space is a priority for regional economic growth and to attract commercial investment from space companies.
Among those receiving government funding is ‘AstroAgency’ which operates across Scotland on behalf of the Scottish Space Leadership Council.
As we have mentioned in previous articles in the Voice, Scotland is well positioned geographically for the launch of small satellites into orbits used for communications and earth-observations and the UK government has asked US aerospace giant Lockheed Martin to identify suitable locations for space port development.
Earlier this year planning permission was granted for a space port at the A’Mhoine Peninsula in Sutherland.
The port is backed by Highlands and Islands Enterprise (HIE) in conjunction with the UK Space Agency and British Aerospace Company Orbex who are developing a ‘Prime’ launch vehicle for the site and have already secured contracts for six launches of commercial satellites.
Highland Council received 457 objections and 118 representations in support of HIE’s planning application. Among the objections raised were the impact on the environment, including the Caithness and Sutherland Peatlands Special Protection Area, and health risks.
However, the local authority approved the plans in June and referred their decision to the Scottish government for scrutiny. But ministers declared that their permission was not required, and the decision should be made by Highland Council.
Danish billionaires Anders and Anne Holch Povlsen, who own land near the proposed Space Hub Sutherland, have also expressed concerns about its impact on vulnerable protected areas and their company ‘Wildland Ltd’ is seeking a judicial review of Highland Council’s planning approval.
Mr Povlsen, owner of the ‘Bestseller’ retail clothing empire said to be worth £4.5billion, and his wife have bought up around 220,000 acres of Scottish countryside across 12 estates.
However, they have also invested almost £1.5million in the UK Space Agency approved Shetland Space Centre being developed by Lockheed Martin on Unst.
Perhaps a case of recognising the possible financial gains tempered by a bit of NIMBYism? Not that unusual perhaps in the world of billionaires.
It should always be remembered though that although space activities are usually presented to the public in terms of their possible commercial value, the military dark side is always present.
Space operations are often of use to both the commercial and military sectors and UKspace, the trade association of the British space industry, is working closely with the RAF to establish a Commercial Integration Cell (CIC) at the MoD’s Space Operations Centre (SpOC) in High Wycombe.
A similar set up to that currently operated by the US Space Force at the Combined Space Operations Centre in Vandenburg Air Force Base in California which is also improving interoperability between members of the US Space Command’s Operation Olympic Defender (OOD).
OOD was established to build international partnerships to ‘deter adversaries and hostile acts in space’ and the UK was the first nation to join in 2019.
The UK is also the first to obtain access to the US Standardized Astrodynamics Algorithm Library (SAAL) which contains information to help predict the locations and trajectories of satellites and objects in orbit.
Access to SAAL allows partners to better collaborate in space and to streamline multinational military operations across the globe.
It will also increase the ability of the SpOC to collaborate with the US Space Force and share data with the 18th Space Control Squadron, at Vandenberg Air Force Base in California.
How long will it be before we see Scotland becoming directly involved in US plans for space domination, if it isn’t already? Watch this space!

Furthermore, the majority of his handiwork was not even applied to the airplane nose but to the fuselage. However, McCraw also embellished several Vega-built B17s which were assigned to the Air Corps so such a prolific and talented artist who produced more than 100 artworks cannot be ignored.
?Randy? McCraw worked at the Lockheed Vega plant at Burbank on the production lines for the Ventura (known as the Hudson by the British). He was a spray painter and applied the US star emblem on the fuselage but later also became responsible for painting the British roundel insignia used for aircraft destined for the RAF, RNZAF, RAAF and the RCAF.
His first rendering is believed to have been of an angry Japanese face painted into the centre of the white star before he over painted it with the red circle used in the early US insignia. During lunch breaks, after encouragement from his supervisor, he began adding more cartoons and slogans to the side of the Venturas to the amusement of other workers. After being asked to paint a larger more elaborate image on one aircraft for a special occasion the idea took off and he began adding his cartoons to many more as the near-completed aircraft rolled along the line. So popular did they become that suggestion boxes soon began to accumulate dozens of slogans every day from workers for McCraw to interpret and he often credited his design to the man or woman who came up with the idea.
With the Disney Studios located nearby, McCraw favoured the use of their much loved cartoons such as Donald Duck, Pluto and Mickey Mouse for the PV-1 Venturas. However, there were also images featuring Hitler and Tojo as well as other graphics. Many of these cartoons were washed off later but some did make it into the combat zone and can be seen in photos taken on the Aleutians, Guadalcanal and other Pacific locations. Canadians in the RCAF seemed particularly attracted to the cartoons and took care to maintain them.
?Strato Sam? and the ?Vega Kid? were characters created to represent Vega plant workers. ?Strato Sam? complete with his tool box was applied to some of the Vega-built B17 Fortresses and several examples of this little character made it into the 8th Air Force flying out of Britain, as did at least one Disney cartoon. The ?Vega Kid? (a cartoon Naval Ensign) was used on aircraft to be assigned to the US Navy. If anyone can provide a photo of this image applied to an aircraft I would be delighted to see it.

"That's one small step for man, one giant leap for mankind". These were the words quoted when Neil Armstrong from the USA stepped on Moon for the first time. But, Neil Armstrong fine-tuned the quote "That's one small step for a man.." in his last words. The recent space news on Moon confirmed his words.
In the row of nations that marched to the Moon, Isreal will be joining soon after its unmanned spacecraft launch in December 2018 using Space X Falcon 9 rocket from Cape Canaveral in Florida. Following the USA, Russia and China were the other two countries succeeded in the moon landing missions so far.
The spacecraft which is the smallest one to be sent ever (585 kg) is yet to be named and is expected to land on February 13, 2019. SpaceIL CEO Anteby said that the organisation will put the Israeli flag on the Moon. The spacecraft has 2 meters diameter with a height of about 1.5 meters and its image has been unveiled on SpaceIL's official Twitter page.
The cameras inbuilt in the spacecraft shall be taking pictures and videos of the moon's surface and its magnetometer measures the moon's magnetic field. The project took almost eight years with an expenditure of $95 million till now, revealed by the trusted sources from Israel.
Apart from this, ISRO had also announced its plan to explore the southern side of the moon for nuclear fuel Helium-3 in its second lunar mission. Astronauts shall be sent to the Moon by China in 2036 and Russia have plans to send cosmonauts to the Moon.

I'm Colonel Peter Nezamis and on behalf of the more than 900 men and women of the 126 ARW, I want to thank you for your interest in our Wing.The 126 ARW is the oldest Air National Guard unit in Illinois and also holds the distinction of being the first Air Refueling unit in the Air National Guard. The Wing's roots are in Chicago where we spent 77 years evolving from the 108th Observation Squadron flying the PT-1 "Trusty," and O-2H, O-38, and O-47 Biplanes; to a Fighter-Bomber Wing flying the B-26 Marauder, the C-47 Skytrain, and the F-51 Mustang; to a Fighter-Interceptor Wing flying the F-84 Thunderstreak and the F-86L Sabre Jet; and finally our transition in 1961 from an Air Defense Wing to the 126th Air Refueling Wing flying the KC-97 Stratotanker, with the 108th Air Refueling Squadron (the previous 108th Observation Squadron) under its direct control. Today the 108 ARS continues its assigned flying mission with more than 80 years of experience.In 1976, the Wing received the KC-135A Stratotanker and has flown that aircraft to the present day transitioning to the KC-135E in 1983, completing a Pacer CRAG or glass-cockpit modification in 2000, and receiving its currently assigned 8, KC-135R Stratotankers in 2008.Due to a 1999 BRAC-directed action, the 126 ARW was relocated from O'Hare Air Reserve Station in Chicago to Scott Air Force Base in Belleville. During our nearly 10 years at Scott AFB we have seen many changes and will continue our evolution into a true total Joint Force key player for the 21st century.In 2010 our Wing celebrated its 60th anniversary and while we looked back fondly on our legacy and accomplishments, today we remain focused on current operations and the future challenges and missions that lie ahead. The 126th Air Refueling Wing continues to be driven forward by professional men and women who seek a greater calling - the dedicated service to our local communities, the State of Illinois, and the United States of America. | aerospace |

Proof suggests that Mars once had rivers, streams, lakes, and even an ocean. As Mars' atmosphere slowly depleted into outer space, the surface water began to permanently evaporate. Today water on Mars in either frozen in the polar caps or underground. Mars is also referred as the "Red Planet" because the surface of Mars is red.
In Greek, Mars was known as Ares. Assuming you weighed 70 lbs (32 kg) on the Earth, you would weigh about 27 lbs (12 kg) on Mars. | aerospace |

(2018 – Scott Dworkin-Mach 91 Aerial photos for Bell Helicopter)
Senior leaders of the Army are now advancing and refining the plans to increase the speed of development and delivery of a new, faster, more lethal and high-tech Future Vertical Lift aircraft currently scheduled to be operational by the 2030s.
FVL is an Army-led joint program for the construction of a family of next-generation aircraft to start emerging in the 2030s, consisting of an attack, utility and heavy-class air assets. Ultimately, the FVL effort strives to replace the Apache, Black Hawk and Chinook.
“On the left of the current path, 2030s is what we look for. The Army leadership desires to be this early. That is the reason why a Cross-Functional Team stood up to figure out what needs to be done,” Maj. Gen. John Ferrari, Director, Program Analysis and Evaluation, G-8, told the Warrior Maven in an interview earlier this year.
With the technology demonstrations are already well underway, the service works on the Initial Capabilities Documents intended to provide an overview of the weapons of applications, and a new tech demonstrator drone in support of the aircraft, senior Army developers said. .. (stay tuned for Warrior Maven detailed reports on this)
The current development of the strategy, which consists of the construction of the first “demonstrator” aircraft Bell and a Boeing-Sikorsky teams, wants to both take advantage of the most promising and cutting edge short-term technologies while engineering systems may also be in line with longer-term plans. Rapid prototyping and experimentation are fundamental to this evolving process, Ferrari explained.
“We have the world’s largest helicopters. Now, the big decision is when do we bring in new technology and how it fits into the long-term plan,” Army Vice chief of staff Gen. James McConville, told a small group of reporters earlier this year.
Requirements for medium utility FVL helicopter, include the construction of a new aircraft to achieve with the aircraft-like speeds while retaining a helicopter-such as the ability to “move” and manoeuvring in close proximity to enemy ground forces.
Army plans also try an aircraft able to reach speeds of more than 230 knots, float in the air at 6,000 feet and 95 degrees Fahrenheit, the reach of a battle with a radius of at least 434 miles and be configured to be emerging sensors and mission equipment technologies will probably occur by the 2030s.
As part of this comparison, the future of the aircraft is intended to make use of fuel-efficient engine technology for a plane to travel at least 800 miles on a single tank of fuel. Such a possibility will enable the aircraft to operate more easily in a single mission without Forward Arming and Refueling Points, or FARPs.
The idea is to engineer and aircraft can fly from the west coast to Hawaii without refuelling.
A faster, more agile helicopter that will fly further on a tank would be able to forces in the fight to be more effective to engage in more combat operations, such as destroying enemy targets, or the transport of small groups of mobile, lethal ground fighters. The new helicopter will also be designed for the next generation of sensors to find enemies on the move and the recruitment of the next generation of weapons to attack them, Army officials describe.
Other important parts of the technical exploration, McConville worked out, are the examinations of aerodynamics, aircraft configurations, new sensor technology and the physics of the advanced helicopter flight.
“We will see where the technology is to determine what is feasible,” Ferrari said.
Bell & Sikorsky-Boeing Design
The Bell offering, the so-called V-280 Valor, focused tilt-rotor technology, in which a winged aircraft with two rotor blades on each wing are trying to achieve with the aircraft speeds and retain an ability to float and maneuver like a helicopter.
The V-280 Valor is designed to be slightly larger than existing Black Hawk helicopter and 24-inch seats to carry 11 passengers with gear, Call developers said. The V-280 Valor has been flown and tested extensively; Bell has recently presented weapons/attack variant. (..stay tuned for Warrior Maven V-280 Valor profile..)
Bell is planning to build on and advance existing tilt rotor technology such as that currently in operation in the Bell-Boeing V-22 Osprey aircraft. The Osprey has two rotating blades, which are vertically aligned when the device is in the helicopter mode and then to a horizontal position when the device enters airplane mode and reach speeds of more than 280 knots.
The V-280 Valor also has two screws that rotate from horizontal flight to a vertical position, which makes it possible for helicopter mode. Bell officials have said that their new devices can reach speeds of 280 knots. Bell and Army officials declare that their V-280 Valor significant progress tilt-rotor technology.
The V-280 Valor uses a straight wing compared to a V-22 that is not right. Bell is also the build up of extra flapping in the rotor system and individual controls that should provide greater low-speed maneuverability, the Army and the Bell developers added.
Officials say the Osprey will continue to do well in a wide range of missions and has been selected by the Navy to perform the Carrier onboard Delivery, or COD, mission of the transport of troops, equipment and weapons on-and-off vessels.
The Sikorsky-Boeing demonstrator, called the SB >1 Defiant, makes use of a coaxial rotor system configuration. This is a design structure, referred to as a composite configuration, which relies on two counter-rotating rotor blades on the top of the aircraft and a pitch mechanism in the back of the car.
“To a rotorcraft to go fast you have to off-load the rotor lift to something else or else you’re in trouble when you try to reduce the speed of the rotor. Usually you do that with a wing, but Sikorsky-Boeing came up with a lift-offset design,” an Army of FVL program manager told Warrior Maven last year.
The pusher-prop at the rear of the aircraft is a small propeller behind the contra-rotating rotor heads. It is what can give of the plane of plane-like speeds. It works with the so-called positive and negative pitch, allowing the aircraft to lean up or down and move forwards and backwards, to the written materials of Boeing.

In response to a call from Dr. Ghassem Asrar of NASA HQ's Science Mission Directorate for "Exploration Science White Papers", we have summarized into a 2-page whitepaper the contributions to the SOFIA SURF Science Opportunities Workshop. The text of the whitepaper is posted here.
In order to investigate the science questions that can be addressed in potential future research experiments on SOFIA's Upper Deck in the twenty years after deployment, NASA Ames Research Center, Moffett Field, Calif., hosted a SOFIA Upper Deck Science
Opportunities Workshop on June 22-23, 2004.
Goal: The primary product of this workshop was to clearly articulate important science questions that such upper deck experiments would address uniquely. Note that no decision has yet been taken for such future use of SOFIA's Upper Deck and any implementation will be only after normal airborne observatory operations have commenced.
The Scientific Organizing Committee consisted of
Peter Jenniskens (SETI Institute),
Hansjuerg Jost (BAER Institute),
Mike Taylor (Utah State University),
Ray Russell (The Aerospace Corporation),
Tim Castellano (NASA Ames Research Center),
Frans Rietmeijer (University of New Mexico Albuquerque),
Hans Stenbaek-Nielsen (University of Alaska Fairbanks),
Leonhard Pfister (NASA Ames Research Center)
The workshop is supported by NASA's APRA program and Earth Science Enterprise research programs. The workshop and its reporting is facilitated by the NASA Ames SOFIA Program Office and will be executed by the SETI Institute and the BAER Institute.
Some examples of potential future upper deck research are outlined here.

Immediately after the 2004 SOFIA SURF Science Opportunities Workshop, NASA gave participating researchers an opportunity to study the reentry of the Genesis Sample Return Capsule from an airborne platform. This provided new opportunities for development of instruments suited for deployment on SURF. The mission was executed as planned. A second mission is being prepared for the January 15, 2006, return of Stardust. More information: here.
Tim Castellano of NASA Ames Research Center reports in the March 2004 issue of Sky & Telescope that a recent partnership agreement between Transitsearch and NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) Education and Public Outreach program will allow Transitsearch volunteer observers to compete for the opportunity to fly as outreach partners on SOFIA's modified Boeing 747 jet in 2005 and beyond. Transitsearch is a collaboration of amateur astronomers and was founded by Greg Laughlin and Tim Castellano to find transiting exoplanets. | aerospace |

Balloon Chasing Three
The other night the balloons easily made it into the farm country. The problem with farms is that there may still be a crop in the field waiting to be harvested. Landing in the wrong field results in an angry farmer and a big expense to the hot-air balloon flight company.
This balloon is skimming over a field of beans, I believe. The pilot brought the balloon out of the field and landed it beside the barn where the pick-up vehicle was already waiting. No damage, no expense, no angry farmer. We might of even had a quite happy farmer, if the pilot and his passengers shared their champagne. (Champagne to celebrate a successful landing is a ballooning tradition.) | aerospace |

Boeing recognizing the lucrative possibilities designed a plane for that market segment.
This monoplane helped the market shift away from the traditional biplanes of the time with its sleeker design. According to Boeing, the plane had a wingspan of over 59 feet and a length of just under 42 feet. The wing was set lower, and its smooth build was made of entirely metal and had no struts. The early form of the standard modern plane can be seen in the structure of this model.
Other vital advancements of the Monomail include its retractable landing gear and the streamlined fuselage. Moreover, its engine was covered by an antidrag cowling, adding to the aerodynamic design of the plane.
The first edition of the Monomail was the Model 200. Much like several pioneering aircraft of this era, it was a mail plane. It saw success on a route between Chicago and San Francisco from July 1931.
The unit weighed 8,000 lbs and could accommodate approximately 1,500 pounds of goods. It could reach a range of 500 miles with a top speed of 158 mph and a cruising speed of 135 mph. Additionally, it could hit a ceiling of 14,700 feet with its 575-horsepower Pratt & Whitney Hornet B engine.
Unfortunately, pilot Alva Lucas crashed a monomail while delivering mail from Montana to Wyoming in October 1935. According to Colorado Wreck Chasers, the aircraft descended too soon and impacted terrain 13 miles south of Glendo.
Boeing also designed another variant for passenger use in the form of the Model 221. This edition’s fuselage was stretched by eight inches and gave up some shipping capacity to carry six passengers. Additionally, the plane’s pilot handled the front in an open cockpit, taking off for the first time on August 18th, 1930.
However, it was the introduction of the transcontinental passenger service aircraft, Model 221A that left an even bigger impact. This model revised the earlier units with slight fuselage extensions to enable a cabin that can hold eight passengers inside. This type saw commercial success as United Airlines (then United Air Lines) took it on for its Cheyenne to Chicago operations.Boeing admits that one of the significant drawbacks of the Monomail was that it was ahead of its time. The design was too progressive for the engines and propellers that were around
The plane needed a low-pitch propeller for departing and a high-pitch propeller to cruise while in the air. However, by the time variable-pitch propellers arose, new multiengine aircraft entered the market. Subsequently, the 200 Monomail was retired in 1933
Nonetheless, it was the Monomail that set the standard for these modern planes. The designs of the B-9 and the P-26 Peashooter, both drew inspiration from the Monomail.
Additionally, the Model 247 is perhaps the most crucial offspring from the Monomail. The airliner was operated by both commercial airlines and the military. Key holders included Avianca, Lufthansa, Canadian Pacific Airways, the United States Army Air Corps, the Royal Air Force, and the Royal Canadian Air Force. Therefore, the aircraft indeed catalyzed Boeing’s international presence.
Altogether, the Monomail lived a short but impactful life. Its emergence in the 1930s helped shape the aviation industry for one of its most important periods heading into World War II. US aviation was able to build on the revolutions that the aircraft offered to take operations to greater heights throughout the century. What caused the retirement of the Boeing Monomail was the airlines getting the contract to deliver the mail and it created a scandal in the process.
Charges of corruption in the air mail system led President Roosevelt to cancel all air mail contracts. The Army resumed carrying the mail.Federal reforms enacted in 1930 gave most routes and air mail contracts to big airline holding companies. Small, independent airlines complained this was unfair, even though most had sold their own contracts and some did not even exist when the law was passed.
The independents fought to break the holding companies' power. Their efforts led to congressional hearings and unfounded charges of corruption and conspiracy to monopolize the air mail. Responding to political pressure, President Franklin Roosevelt canceled all domestic air mail contracts on February 9, 1934. The Army Air Corps was again called upon to carry the mail. | aerospace |

So when someone hit him with the idea, he already thought about it.
In August 21, 1957 the first missile was launched. They called this missile the intercontinental ballistic missile or the ICBM. Everyone wanted to be the first nation to the moon.
In October 4, 1957 they started making advanced satellites up in space. They said that this was the first artificial satellite. They also said that it was the first signals from space.
In November 3, 1957 the first dog got into orbit. They were experimenting what that would do in order to send the first man to space. So they thought this was the best idea.
In January 31, 1958 the first U.S satellite was used. It was very helpful pretty much as soon as the US built it. It was the detection of Van Allen radiation belts.
As a result Apollo made it to the moon and the US was the first successful nation to travel to the moon. Apollo made himself and the whole country proud of him. All nations were jealous and tried to do as he did. | aerospace |

Japan Aerospace Exploration Agency placed the PV panels on a supply ship to the ISS.
Jan 10th, 2017
(Image: JAXA) As noted by Tech-On!, the Japan Aerospace Exploration Agency (JAXA; Tokyo, Japan) has revealed that it mounted thin-film triple-junction solar panels on the "Kounotori No. 6," an unmanned Japanese spacecraft launched on December 9, 2016 from Tanegashima Space Center to ship supplies to the International Space Station (ISS). The position where the photovoltaic (PV) panels were installed is used as a platform for verification tests. The verification test of the solar panels will be carried out in orbit and will last until reentering the aerosphere. The solar panel, which was developed by Sharp (Osaka, Japan), combines three kinds of solar cells made from III-V semiconductor materials that each use a different spectral region for PV conversion. The conversion efficiency of the solar panel is about 32%, which JAXA claims is the world's highest efficiency for a practical space-based solar panel. The previous efficiency record was 29.5%. In May 2016, Sharp announced that it had achieved a module conversion efficiency of 31.17% with triple-junction compound solar cells in a nonconcentrating configuration. The individual size of the new solar cell is about 27 cm2, and its weight is as low as 0.33 g. The weight reduction was realized by using a plastic film as a substrate. Sharp's previous space solar cell uses a glass substrate and weighs 2.2 g. The film substrate is not only lightweight but also flexible and can be attached to the main body of a satellite. The system for the verification test is equipped with instruments for measuring current, voltage, and temperature of the solar panels.

Mission controllers on the ground established a regular cadence of observatory communication and control activities. The large instrument reflector boom was deployed according to plan, and the reflector was then unfurled. Final adjustments to SMAP’s orbit was made. The instrument was carefully spun up to its operational 14.6 rpm spin rate. The instrument was then fully powered on and checked to insure it is healthy. The science data processing system on the ground established the routine on-going processing of instrument data. During commissioning, the ‘first light’ science data images were released to the public to confirm that the observatory was operating and ready for its next phase of activity.
Routine Science Operation
The SMAP science operation started in April 2015. During and after the first year of intensive calibration/validation (Cal/Val), the SMAP observatory and ground operation systems operated in a repeating cycle of activities to communicate and command the spacecraft, and receive and process the data on the ground. SMAP uses a significant amount of automation in this process to reduce operating cost. Trained operators manage this process and monitor the health of the observatory and ground system and perform routine maintenance. When problems arise with the observatory or ground systems, they are ready to quickly respond and return the systems back to operation. The prime mission of SMAP was completed in summer 2018 with three years of science data for a wide range of research. Since then, SMAP has been approved to operate in extended phase through 2023. Future extensions will be reviewed every three years.
After the failure of SMAP L-band radar, European Union’s Copernicus Sentinel-1 synthetic aperture radar data with a full global land coverage every 12 days starting mid-2017 were used as a surrogate. The SMAP-Sentinel-1 combined data have been used to produce soil moisture products at a spatial resolution of 3 km since June 2018.
Calibration and Validation (Cal/Val)
Like any complex scientific instrument, the SMAP observatory’s data must be calibrated and validated so that the processed soil moisture and freeze-thaw data are accurate. For SMAP, this is immensely complicated because the data must be checked over the very diverse soil types, land cover, topography, weather and other atmospheric conditions that occur over the Earth’s varied continents and that can also change over the seasons. This is a step-wise process that starts with calibrating the lowest-level (“Level 1”) raw data from the instrument (radar “backscatter” and radiometer “brightness temperature”) against known ‘standards’, including other calibrated aircraft & spacecraft instruments and different well-characterized locations around the globe, including the amazon forest canopy and the oceans. Uncalibrated (‘beta’) Level 1 data were released 3 months after commissioning was completed, and fully calibrated Level 1 data were released 6 months after commissioning.
With the Level 1 data calibrated, the next step is to validate the ground processing that produces the higher level soil moisture and freeze thaw data from the lower level data. During this step, soil moisture data is compared with numerous sites around the globe that have been outfitted with soil moisture probes – these sites have been set up for other scientific research, but SMAP is able to use them to compare and adjust soil moisture measurements over the very diverse conditions over which the measurements must be made. Validation is also augmented by comparing SMAP’s data with aircraft instrument measurements made at the same time and locations. Unvalidated (‘beta’) soil moisture data (Levels 2, 3, and 4) were released 6 months after commissioning was completed, and fully validated data will be released 12 months after commissioning. The fully validated freeze-thaw data was released 15 months after commissioning. The special SMAP-Sentinel-1 product was released in June 2018.
The intensive Cal/Val campaign that precedes the first release of calibrated and validated data ensure that it meets accuracy requirements established by NASA for the mission. However, Cal/Val will be ongoing throughout the mission so that the data quality will continue to be gradually refined and improved over time. After this first year of operation and occasionally thereafter, all of the acquired data have been reprocessed annually to incorporate improvements and refinements in the processing and ensure the entire data is consistently processed.
At the end of the mission’s useful life, the observatory will undergo a disposal process that will safely remove it from Earth’s orbit in a relatively short amount of time (less than 25 years), so that it does not remain in orbit as a source of debris to threaten other operating missions. | aerospace |

NASA's planned flight of space shuttle Endeavor atop a 747 has been postponed until Wednesday due to an unfavorable weather forecast.
Endeavor is scheduled to conduct low-level flyovers at about 1,500 feet above locations along the planned flight path. The exact timing and path of the ferry flight will depend on weather conditions and other factors.
Endeavor will depart Kennedy's Shuttle Landing Facility and is expected perform a flyover of various areas of the Space Coast, including Kennedy, the Kennedy Space Center Visitor Complex, Cape Canaveral Air Force Station and Patrick Air Force Base.
The aircraft will fly west and is expected conduct low flyovers of NASA's Stennis Space Center in Mississippi and the agency's Michoud Assembly Facility in New Orleans. As it arrives over the Texas Gulf Coast area, it is expected to perform low flyovers above various areas of Houston and Clear Lake before landing at Ellington Field near NASA's Johnson Space Center.
When the craft departs Houston it will make a refueling stop at Biggs Army Airfield in El Paso, Texas, and conduct low-level flyovers of White Sands Test Facility near Las Cruces, N.M., and NASA's Dryden Flight Research Center at Edwards Air Force Base in California, before landing at Dryden.
The next day, Endeavor will take off from Dryden and perform a low-level flyover of northern California, passing near NASA's Ames Research Center at Moffett Field, Calif., and various landmarks in multiple cities, including Sacramento and San Francisco. The aircraft also will conduct a flyover of many Los Angeles sites before landing at LAX.
After arrival at LAX, Endeavor will be removed from the 747 and spend a few weeks at a United Airlines hangar undergoing preparations for transport and display. Endeavor then will travel through Inglewood and Los Angeles city streets on a 12-mile journey from the airport to the science center, arriving in the evening on Oct. 13.
Beginning Oct. 30, the shuttle will be on display in the science center's Samuel Oschin Space Shuttle Endeavor Display Pavilion, embarking on its new mission to commemorate past achievements in space and educate and inspire future generations of explorers. Endeavor completed 25 missions, spent 299 days in orbit, and orbited Earth 4,671 times while traveling 122,883,151 miles. | aerospace |

Based on the open-source imagery by the European Space Agency (ESA), the platform is free to use for research purposes, while commercial users would have to pay at least €275 per month for unlimited usage.
Terramonitor says it uses artificial intelligence algorithms to piece its maps together from some 100 million images from ESA and update them as the fresh photos are published. The solution is aimed first of all at organisations working in the areas of forestry, infrastructure, agriculture, and environmental research.
The satellite imagery provided by Terramonitor is available in the web browser, but can also be integrated with its clients' geographic information systems (GIS) of choice. In addition to the most recent photos from the orbit, the system can show historical data going as far back as the summer of 2015.
Having access to the satellite imagery doesn't always mean you can see how any part of the planet's surface looked on any day. Although the delay between the images landing at the ESA servers and becoming available at Terramonitor is just several hours, quite a few areas on the map are comprised of photos shot last month.
“The images are taken twice a week, but as you can imagine, most of the images are usually covered by clouds and are not usable, or eye-friendly,” Terramonitor told tech.eu. “The Terramonitor AI algorithm detects and removes these images to provide high-quality and comprehensive mosaics.”
This is also the main difference between Terramonitor and similar services, according to the startup. Most of the competing imagery providers would send across the photos with metadata comments like “The Netherlands, 80 percent cloud,” leaving it to the end user to look for images where anything meaningful can be seen.
Terramonitor has a team of seven people and is going to join ESA's Business Incubation Centre later this year. The one-year incubation program is there “to work with and inspire entrepreneurs to turn space-connected business ideas into commercial start-up companies.” The company has also raised an undisclosed funding round from a VC firm. | aerospace |

“This is the new Air Force One,” he said, explaining that the model represents an updated version of the presidential plane that will cost taxpayers less money and offer more new features than originally planned, thanks to his intervention.
“It’s going to be terrific,” he added as he met Justin Trudeau with a model on the table of his proposed design.
Long fascinated by airplanes, Mr Trump has always fancied himself as something of an aviation expert.
Mr Trump once owned the now-defunct, New York-based Trump Shuttle in the late 1980s and early 1990s, and he took great pride during the 2016 presidential race in using his personal plane, a Boeing 757 with Rolls-Royce engines and gold fixtures, to whisk him to campaign events and back to his New York penthouse.
He recently advised Boeing to fix and rebrand its troubled 737 Max jetliners with a new name after the planes were grounded worldwide following deadly crashes in Ethiopia and Indonesia.
So fond was Mr Trump of his personal plane that he mused about continuing to use it after he took office, which was not a realistic option for security and other reasons.
Mr Trump views the colour scheme as dated, too muted and insufficiently patriotic, according to several current and former White House and campaign advisers.
“The baby blue doesn’t fit with us,” he told Fox News last week after earlier unveiling sketches of his ideal redesign for the plane’s exterior.
Using the colours of the American flag, the top half of the plane would be white while dark blue would cover the bottom half, including the belly.
A bold red stripe would streak from cockpit to tail across the midsection — almost identical to the colour scheme on Mr Trump’s personal plane, except that the white and blue are reversed.
Mr Trump acknowledged the historic nature of the existing Air Force One design, but said it has been around a long time.
“I like the concept of red, white and blue and the classic, and I think it’s going to look much better actually,” he told Fox News.
Mr Trump’s proposed design is far from a done deal — Democratic politicians want congressional approval of a new Air Force One paint job.
The amendment still must make it into the final version of the legislation that Congress sends to Mr Trump.
“This plane’s going to be around for the next 20, 30 years, so let’s keep that in mind, and if someone wants to change its appearance, its scheme, then we ought to have a say about it,” said Representative John Garamendi, a Democrat committee member.
“Personally, I think we ought to stay with what we have.”
Others questioned Mr Trump’s colour choices, especially a darker blue for the belly over the lighter blue on the plane that took Mr Trump to Florida and back this week.
Alex Major, co-head of the McCarter & English government contracts practice and a retired Air Force intelligence officer, said a darker belly would not be “visually benign” and could make it easier to detect Air Force One in the sky.
“When you have a light blue belly, it’s there for a reason,” Mr Major said.
Before taking office and as his transition teams and inaugural committee laboured over new hires and details of the swearing-in, Mr Trump tweeted in December 2016 that costs for the Air Force One programme were “out of control, more than four billion US dollars.”
He added, “Cancel order!”
White House press secretary Sarah Sanders later said the Air Force had awarded Chicago-based Boeing Co a 3.9 billion US dollar contract for two presidential planes due in 2024, the final year of a possible Trump second term.
The price tag represented a savings of 1.4 billion US dollars over an initial contract proposal, she said.
Boeing said its livery experts helped the White House Military Office with the design scheme.
Air Force spokeswoman Ann Stefanek confirmed that red, white and blue livery options are being considered.
Mr Trump has grown fond of using Air Force One as a campaign rally backdrop, and he often summons aides to watch live coverage, usually on Fox News, as it descends into international airports.
According to Boeing history, first lady Jacqueline Kennedy picked new colours for the plane used by her husband, President John F. Kennedy.
Baby blue covers the nose and sweeps back along each side of the fuselage.
The lettering was changed to a font inspired by the heading of the Declaration of Independence.
The livery was the work of French-born industrial designer Raymond Loewy, whose previous clients included Lucky Strike cigarettes and Studebaker cars.
He wrote that President Kennedy picked the blue paint scheme over a red one.
Some accounts said he rejected the Air Force’s red and gold theme because it looked too imperial. | aerospace |

But the Air Force plans to make a major change to the way it trains and manages its pilots in Iraq and has begun to consider whether it can do the same for its combat-ready pilots.
The Air Force has been planning for this transition for more than a year.
It has been looking at ways to use more advanced training and equipment in Iraq, and it is now considering a “tentative” deployment of up to 500 U:1 trainers in Iraq over the next year.
That could allow the Air National Guard to train as many as 4,000 pilots over the course of four years, officials say.
The new training would include a mix of training with pilots and ground troops, and include more in-person courses and online courses for the first time in a long time.
The move comes as the Air Forces has been grappling with a growing number of pilots who are retiring, and a shortage of qualified pilots and mechanics.
In 2016, there were just 8,000 in the Air Reserve.
In 2017, that number was down to 7,700.
Officials say the air force has to find more pilots who can serve as frontline aircrew to help with the fight against ISIS.
The Trump administration has repeatedly threatened to withdraw the U1, a military version of the Airborne Warning and Control System, or A-10.
But officials have said they are committed to keeping the U2 airframe in Iraq to help train and equip the country’s air forces, and they are considering moving the U-2s to other airfields.
That would be the most significant change in air power in Iraq since the Ulloa program in 2008.
The decision on the new air force is expected to be made in the coming weeks, Air Force officials said.
The U:22 aircraft would be used for training missions in Iraq.
They would be equipped with infrared sensors and cameras that could detect enemy aircraft and provide the ground crews with intelligence.
It would also be equipped to carry out surveillance missions in and around Mosul, the capital of the country.
It’s not clear what kind of training will be offered to the U of A’s pilots, but officials said the UAV could be used to gather intelligence on ISIS.
The pilots could use it to train with other aircrews, who would be able take their own flight lessons and pass them along to the other air crews.
“We have the ability to use that to train and we have the capability to use it for the training of aircrew,” Air Force Maj. Gen. Matthew Burt, commander of the 1st Air Force Training Wing, told The Washington Post.
“The UAV provides the ability for us to have our own pilots and aircrew train with us, and we can use it in a variety of ways,” he added.
The military is also exploring other ways to train air crews in Iraq that include sending them to a combat zone, but the military has yet to decide on what that training might look like. | aerospace |

With few exceptions, you can use your phone to text, call, and get online from pretty much anywhere in the country. Yet about 2 billion people around the world live in areas that lack mobile coverage, mostly far from major cities, which makes building a network of terrestrial cell towers to connect them prohibitively expensive. If you built a cell network in space, it could plug the gaps in global mobile coverage by raining 4G service from satellites to users on the ground.
Satellite phones have been around for decades, but they are expensive and their brick-like form factor was inconvenient for everyday use. Now a handful of companies are working to fix this problem by building satellites that can connect to regular cell phones and provide high-bandwidth mobile data anywhere on earth.
Building an extraterrestrial mobile network is tricky because cell phones aren’t designed to communicate with satellites whizzing by at 17,000 mph, 300 miles above the ground. Instead, their software and hardware is optimized to connect with stationary cell towers that are never more than a couple dozen miles away. If you want to connect with cell phones from space, you need an antenna that is sensitive enough to collect their weak signals and powerful enough to return a signal that can be picked up by a cell receiver.
“The hard part is the uplink from the phone,” says Charles Miller, cofounder and CEO of Lynk, a satellite communications company based in Virginia. “You can’t change the phone to add more power. It needs to work out of pocket.”
Within the next two years, Lynk plans to create a constellation of shoebox-sized satellites that will function as orbiting cell towers. Each satellite will use a modified version of terrestrial cell tower software that corrects for things like the Doppler frequency shift caused by the satellite rapidly passing overhead and the delay from sending a signal to space and back. The satellites operate on a relatively low frequency compared to other communications satellites, which means they can tap into the part of the spectrum used by cell phones on earth. Miller says the company has developed an antenna that is both sensitive and powerful enough to communicate with cell phones on earth, but declined to get into specifics of the technology.
In early 2019, Lynk sent its satellite technology to orbit on a Cygnus cargo capsule that docked at the International Space Station. Although it wasn’t a standalone satellite, the payload consisted of Lynk’s core technology and the company demonstrated it could communicate with mobile devices on earth over a 2G network. Since then, the company has launched two other satellite testbeds to the space station and plans to launch a fourth later this month. If all goes well, the next step would be to start launching actual satellites into orbit.
Miller says the company could have a functional satellite cell network as soon as 2022, but it won’t provide global, around-the-clock coverage at first. When the network only has a few dozen satellites, they might pass over users every 90 minutes or so and only provide a few hours of connectivity per day. As more satellites are added to the system, the coverage will improve until the experience of connecting to an orbital cell tower is no different than connecting to a terrestrial one.
But Miller says even a limited connection is better than nothing. “If you’re in a remote area and you only get coverage when you go into town on the weekends, but now you can send and receive messages when a satellite passes over, that’s a valuable service even if it’s only available every hour,” Miller says.
Lynk was joined in space last year by the Texas-based satellite communications company AST & Science, which launched its first satellite, BlueWalker 1, to low-Earth orbit to test their software. AST is building a new, unproven type of satellite constellation that’s a riff on so-called “fractionated satellites,” which divide the capability of one large satellite among several smaller ones. For example, one satellite might host a scientific payload, while another might be responsible for communicating with ground stations. The two would communicate with one another through wireless links. A fractionated satellite system has never flown in orbit, although Darpa spent six years and more than $200 million dollars developing a fractionated satellite before abandoning the concept in 2013 due to budgetary constraints.
AST’s system will consist of dozens of small, pizza box-sized satellites flying in formation as they receive cell signals. According to AST’s founder and CEO Abel Avellan, the system isn’t truly fractionated because each of the small satellites will have the same capabilities, rather than splitting the functionality of one larger satellite. But the formation will be managed by a large control satellite, which will direct network traffic and satellite movement like a conductor leading an orchestra. Although the later versions of the satellites in AST’s system will communicate with one another over Wi-Fi or a similar wireless protocol, Avellan says the first satellites to go up will be physically connected.
The advantage of AST’s approach is that the satellites can be spread out over hundreds of feet. Since each satellite is itself a receiver and is working in tandem with the others, this has the effect of creating a massive antenna. “In essence we are building a very, very large satellite with a lot of power that can connect directly to a handset,” says Avellan. “Our system is a replica of the terrestrial network in space.”
Nothing quite like AST’s vision for its space cell network has ever flown in space, but the audacious plan has already attracted some high-profile support. On Tuesday, the company announced it had raised $128 million in funding to kickstart the network. The funders included Vodafone, the world’s largest mobile provider outside of China, which hails the technology as key to getting the rest of the world online. “We don’t see anything else out there that is going to allow us to connect the next couple of billion people in the world that we aspire to with this platform,” says Luke Ibbetson, the head of group research and development at Vodafone who is leading the company’s collaboration with AST.
Lynk and AST & Science are leading the race to build a cell network in space, but they may be joined by Apple, which has been reported to be building space phone technology. Last year, Bloomberg reported that Apple “has a secret team working on satellite technology that the iPhone maker could use to beam internet services directly to devices, bypassing wireless networks.” It’s uncertain whether Apple plans to develop its own satellite constellation. Apple did not respond to WIRED’s request for comment.
Despite the burgeoning interest in space-based cell networks, the idea itself isn’t new. In the mid-2000s, a company called TerreStar also sought to create a 4G satellite network that would connect with devices that were a hybrid of satellite phones and regular cell phones. The device, known as the Centrus, looked a bit like a Blackberry and was designed to be able to switch between terrestrial and satellite cell networks. Alas, no one ever really had a chance to use the thing. TerreStar filed for bankruptcy in 2010, just a few months after it launched its first satellite.
Avellan says this time things are different. He cited the rapidly falling cost of space access thanks to reusable rockets, as well as the miniaturization of key technologies such as software-defined radios as the main reasons that space-based cell networks are finally viable.
Both AST and Lynk executives see it as their mission to bring cell coverage to people who lack access to emergency communications, weather reports, banking, and other benefits offered by mobile devices. Many of these people are concentrated in India, Indonesia, and equatorial Africa, but Miller says space-based cell service will be valuable to people who live anywhere out of the reach of cell towers, which he calculates to be about 75 percent of the planet.
“If you go an hour outside of Washington, DC, into western Loudoun County, there are plenty of areas even on major arterial roads that have no connectivity,” Miller says. “It’s just the economics of cell towers—you can’t afford to build them everywhere.”
The big question is whether anyone will pay up for space-based satellite service even if the technological hurdles are overcome. Both Lynk and AST have struck partnerships with telecommunications companies that are helping them integrate with their networks to test the space-based cell service. When the satellite networks are ready, Lynk and AST will sell the service to telecommunications companies that will roll the satellite service into existing plans and presumably extend these services to places where people don’t have cell connections. But will they be able to find enough customers who want to pay when service is still spotty and might only be available for a couple hours per day? Without a substantial user base, it may be difficult for space-based cell networks to raise the massive capital needed to launch enough satellites to provide global, around-the-clock service.
“The plans are ambitious, but they’re credible,” says Ibbetson. “We’re a few years off from actually launching service, but the signs are all extremely positive.”
Both Lynk and AST have a lot to prove. The history of commercial space exploration is rife with companies that built great technology yet couldn’t find enough customers before their coffers ran dry. Although both companies have conducted some successful tests of their core technologies in orbit, the market will be the ultimate arbiter of their future—or whether they have a future at all.

During this webinar, report author Almuth Ernsting will present the key findings of the investigation into aviation biofuels developments and future prospects, and will be available to answer questions. The report is being launched ahead of a High-Level Conference by the International Civil Aviation Organisation, ICAO, about “Alternative Fuels for Aviation”, namely biofuels.
The ICAO Secretariat has proposed a vision which would see 32% of global jet fuel made form biofuels by 2040, and 50% by 2050. Questions discussed in the report include:
How would the proposed ICAO vision compare and interact with existing biofuel markets, which are largely for road transport?
What types of aviation biofuels are technically and economically feasible? – Could aviation biofuels be produced on a large scale without palm oil?
Could sustainability and greenhouse gas standards, which are being discussed by ICAO, prevent serious negative impacts on forests, climate and communities from biofuel expansion for aviation?
If biofuels are not the answer, then how can greenhouse gas emissions from aviation be reduced?
The report is available at www.biofuelwatch.org.uk/2017/aviation-biofuels. It was produced with support from Heinrich-Boell Foundation. For more details, including about the webinar, please email email@example.com | aerospace |

Kathy Sullivan, TEDxLondon Climate Curious
Hello, I’m former NASA astronaut Kathy Sullivan, and I’m here to talk with you about space trash.
What is space trash?
Trash is the useless junk that’s been left in space from something like 60,000 launches that have happened since the start of the Space Age. And it ranges from spent rocket motors to lens covers, and even down to paint chips and bits of slag from Rocket motors.
There are over 28,000 bits that are large enough to track the location of from the earth and no doubt, millions of much smaller ones, all of which pack a heck of a lot of impact because they’re moving at very, very high speeds.
How does it end up floating in space?
We send the satellite up. It usually starts with a rocket stage that lifts it the first bit off the earth. That bit usually falls back to Earth or is sent back to Earth and reused, but there’s usually a second stage and sometimes a third stage that gives that satellite another bit of push.
And those rocket stages when they drop away from this satellite, are just left in orbit. They usually have some fuel or propellant left in them. And oftentimes it’s that leftover of propellant that over the years starts to leak or heat up, and may eventually explode the spent rocket stage. So instead of having one rocket cylinder that you could track the location of, you end up with a cloud of particles. Some of them might be big enough to track, and others could be very, very small. But again, they’re moving at tens of thousands of miles an hour.
So if one of them hits you. They’ll pack quite a punch.
Importance of space-based observations for climate action
All those bits, as they slowly decay from their orbit and fall back to earth, they mainly burn up in the atmosphere leading behind.
Some of the chemicals that they were made of. So that might be something to look at. The point that I care most about and worry most about is if space becomes so crowded with junk more than satellites, it could become too hazardous for satellites. You almost could seal off space and make it unusable and space-based observations play a really critical role in helping us understand our planet and how it’s working, and track the trajectory of everything from daily weather to our future climate. The data we get from space is indispensable to both weather forecasts and those kinds of climate predictions, so we need to be able to take the pulse of our planet and satellites in orbit are vital to that undertaking.
The Kessler Syndrome refers to the potential problem that you get so many. Spent rocket stages left in space, for example, they start to collide with each other and each collision creates a cloud of particles that then can glide with other things.
There are projections that say if we stay on our current pathway and don’t get some clearer rules of the road in place, that before too long, the Kessler Syndrome could be what dominates the debris. So now it won’t be a rocket stage explodes, it will be all these other bits keep crashing into each other and crashing into each other and crashing into each other.
So it becomes an exponential growth of the space debris that could, in a sense, clog up Earth’s orbit so much, that we seal ourself off from access to space.
Setting international space rules
So the best way to reduce this trash, in particular the spent rocket stages, is to set up an agreement that you have to design your rocket. Once your second stage booster does its bit, it maybe has enough propellant left to. To deorbit itself slow itself down so it drops back to earth.
Removing existing debris from space – can you shoot it out the sky?
The other thing that’s being looked at seriously to control it is the challenge of removing existing debris from orbit. That’s a really tricky thing to do. I mean, you might think a big net, but this pieces are all moving so fast if you, if you are not matched exactly in the same orbit, every bit of debris would just shred your net.
There’s not really a way to shoot them outta the sky, like in Star Wars, because if you shot at one of the spent rocket stages, you just would’ve made your problem worse.
Soon as you fire something at it, it becomes a cloud of particles, bits and particles that are much smaller and probably hundreds of which you now can’t track. So now you’ve just created a fuzzball of uncertainty. There’s, there’s more stuff up there that’s worrisome and now I can’t tell you where it is that actually makes the problem.
You might think, well, how about a big magnet? So just attract it all and pull it down. , but for various physics reasons, spacecraft are not built out of magnetic materials. There’s nothing magnetic up there to go get. So it’s a challenging problem to be sure.
Threat to satellites and climate data/ tracking
My urgent concern vis-a-vis climate problem is that we really are critically dependent on satellites in space to monitor the earth, to study how it works in ever greater detail.
So if we lost this very precious ability to monitor the earth that would be really pampering to our efforts to solve the chemistry of the atmosphere.
Problem track emissions, track the temperature of the ocean, track circulation, changes in our ocean and our at. Satellites are absolutely critical to doing all of that. So we have to be able to keep our finger on the pulse of our planet, uh, really globally. Uh, and we have to have, uh, we have to have earth observation satellites in place to do that.
So if the debris problem became so severe that as soon as you put a satellite up there, it was likely destroyed within a week, we would effectively be blind. Those kind of trends and changes.`
I’m not a fan of the Lifeboat School of Thought, which says, well, we’ve, we’ve wrecked this planet so badly. It’s imperative that we go off to some other planet, or Jeff Bezos’s vision is not to other planets.
It’s to an array of large Space station communities throughout the Milky Way. I like this planet a lot. I’ve always been curious deeply about this planet. And I think it’s, well, to be blunt, I find that an amoral idea. It says, number one, it’s not gonna save all of humanity.
Those, would in a sense, become the most exclusive gated communities, right? You’re not, you’re not saving billions of people from earth. You’re taking maybe hundreds of thousands or couple million off to Mars as the seed stock for the next generation of humanity. And so who are they gonna be? How’s that chosen?
It’s not gonna be easy living on Mars or the moon, by the way, but it’s a little naive. And secondly, my philosophy about living on this planet is we are all crew members on a spaceship together.
We should be stewards, we should be good caretakers of this really rather exquisite planet that we’ve been given. So the notion that I’m just gonna muck it up and make a mess of it, and then go somewhere else and do it again; I think it’s abhorrent.
For people who’d like to know a little bit more, the European Space Agency and NASA both have good information about the current Space debris problem on their websites.

However, the launch was delayed due to bad weather.
The next launch date is May 17. During the launch from the Space Launch Complex at Cape Canaveral Air Force Station (CCAFS) in Florida, the satellites will be sent to orbit at an altitude of 550 kilometers with the Falcon 9 Block 5 rocket. The launch will take place at 5.30 am Turkey time.
With this launch, the Falcon 9 rocket will have made its 71st flight, and the rocket’s first stage booster, which descends back to earth, will have made its 40th landing. This will be SpaceX’s 6th mission in 2019.
Gwynne Shotwell, SpaceX’s Chief Operating Officer, said on May 7 at the Satellite 2019 conference that dozens of Starlink test satellites will not have in-satellite connectivity capabilities, even if they have onboard antennas and electric propulsion systems. He stated that this flight will be intended to test the deployment strategy for subsequent flights.
In order for the project to reach a conclusion, 420 satellites need to be positioned in orbit. The first functional satellites are expected to be launched in 2020. | aerospace |

The United States Air Force announced Tuesday the long-awaited test flight of his new hypersonic weapon failed, and the prototype missile could not be fired from a bomber plane. Calling the incident a “setback in demonstrating its progress in developing hypersonic weapons,” the service said in a statement that the AGM-183A air-launched rapid response weapon, known as ARRW (pronounced “Arrow”), the propellant was unable to launch from a B-52 Stratofortress during a test on April 5 over the Point Mugu Maritime Range off the coast of California.
“The ARRW program has pushed boundaries since its inception and has taken calculated risks to advance this important capability.” General Heath Collins, executive officer of the Armaments Directorate Program, said in the statement. “While the no-launch was disappointing, recent testing provided invaluable information to learn from and continue; that’s why we tested. “
The Pentagon has shown great interest in the development of hypersonic weapons, that move at more than five times the speed of sound and could act as deterrents, even elements of change, when responding to conflict from hundreds of miles away. | aerospace |
