By Mary Hennock, Adam B. Kushner and Jason Overdorf
From the magazine issue dated Sep 29, 2008
If the weather holds, China plans to celebrate another milestone on its long march to the moon this week in a PR extravaganza that will rival its Olympic performance a few weeks ago. Fittingly, a Long March II-F rocket will take off from the Jiuquan launch center in Gansu province carrying three astronauts on China's third mission to low Earth orbit. After a live broadcast of the launch and heartwarming made-for-TV linkups between the crew and their families, the ruggedly handsome Zhai Zhigang will open the hatch and emerge into outer space. It will be China's first spacewalk and another step in its ambitious plan to build its own space station by 2015 and—if the rumors are true—to put astronauts on the moon by 2020.
The display will no doubt be lauded as yet another indication that China is ready to join the ranks of the world's space titans, Russia and the United States. But are these missions cause for worry in Washington and Moscow? The Soviet Union performed the first spacewalk in 1965 when Aleksei Leonov stepped out of a Voskhod II capsule, and the United States did it later that year when Ed White left his Gemini capsule. Although the ability to launch payloads can also be used to lob bombs, the military implications of a manned program are virtually nil: nobody has yet figured out what humans can do in space that robotic weapons can't do better.
China sees its spacewalk as a way of proving that it belongs with the United States and Russia in the top tier of space-faring nations. But its true opponent in this space race is not the West so much as its Asian neighbors—India in particular. India has in recent years transformed its space program from a utilitarian affair of meteorological and communications satellites into a hyperactive project that seems designed to make a splash on the world stage. Its robotic-exploration program is scheduled to launch a probe on Oct. 22 that will orbit the moon for two years. And Japan is considering expanding its well-established (if less ambitious) space program—which includes research on the International Space Station and a respectable commercial satellite business—and exploring military applications. Against this backdrop, Beijing's dominance is not unshakable. Just as the Soviet Union's launch of its Sputnik satellite back in 1957 was only a fleeting victory, China's recent accomplishments have provided merely the opening salvos in a modern-day Asian space race.
The two biggest forces driving the race between China and India are their insistence on self-reliance and the idea that space exploration feeds national prestige. Naturally, the two ideas work in tandem. India was shut out from NASA and European space missions for years after testing its first nuclear bomb in 1974; now many technologies for its space program have been developed by Indian engineers with little outside help. (India has agreed to carry U.S. and European payloads on its moon launch.) Beijing has watched U.S.- Russian cooperation on the International Space Station rise and fall with their diplomatic relations. "The most important thing is that China has developed and formed its own system for space aviation independently," says Huang Hai of the China Aviation Science and Research Institute. Ouyang Ziyuan, a space expert at the Chinese Academy of Sciences, summed it up to People's Daily: China's program "suggests comprehensive national strength …, increasing China's international prestige and the cohesive power of the Chinese nation."
Beijing's space program electrified the competition when astronaut Yang Liwei orbited the earth in October 2003. Last year China shot down an aging weather satellite, adding an arms-race quality to the battle for prestige. It is now constructing its fourth launch base, on Hainan Island, for a new 25-ton booster rocket that will carry aloft modules for its space station, which will be permanently staffed. Also ahead: robotic moon landings (a data-gathering probe is already in orbit) and even a rumored manned trip to the lunar surface—a prospect that provoked a minor crisis in Washington, culminating in President George W. Bush's State of the Union promise in 2004 to establish a permanent U.S. moon base. Despite technology export controls imposed by the United States, China's commercial satellite business is thriving. It has launched 79 satellites altogether—10 of them in 2007. This year India has launched 11 satellites, including nine from other countries—and it became the first nation to launch 10 satellites on one rocket.
The United States and the Soviet Union were racing in the context of a cold war, but India and China are vying for leadership in a competitive marketplace of people and knowledge industries. It's about developing technology, talent and markets. All of which has stimulated Chinese technology: sensors built for space have ended up in GPS systems, washing machines and other products. The Chinese hope to spin out their rockets and orbiters into inventions and products they can patent. And "they're now right up in the world class of robotics," says British scientist Martin Sweeting, CEO of Surrey Satellite Technology, which built Beijing a pollution-monitoring satellite for the Olympics and does work on China's moon rovers.
None of this has gone unnoticed abroad. China's manned space program "shook up all the neighbors because the Chinese asserted, 'We are the dominant regional power'," says Jim Lewis of the Center for Strategic and International Studies in Washington, D.C. After China used a ballistic missile to blow up the aging weather satellite in January 2007, scattering debris into low orbit, Japan's Parliament overturned a law isolating its space program from military uses, and its space agency is trying to capitalize on the new mood by requesting a 29 percent budget increase at a time when the general science budget is growing by only 1 percent per year. The public, however, worries more about the social problems of an aging population than beating China to the moon. As a stable democracy and charter member of the world's most advanced economies, Japan simply has less to prove.
The repercussions of China's program were felt most strongly in Delhi, where the 36-year-old space program is now ramping up its moon project at launch speed. China first sent a man into space in 2003, and India won't achieve that goal until 2015, but according to unofficial schedules, China will beat India to a moon landing by only a year. Reaching the moon is the childhood dream of Madhavan Nair, chairman of India's space program, which is now spending about $1 billion per year, compared with an estimated $2.5 billion a year in China. If all goes well, at the end of October India will launch the $100 million Chandrayaan-I, its first lunar orbiter, using the workhorse Polar Satellite Launch Vehicle. The orbiter will fire a probe at the moon's surface, kicking up a cloud of lunar dust that scientists will analyze from afar—and it will plant the Indian flag in lunar soil. Its successor, Chandrayaan-II, a cooperative effort with Russia (and, therefore, one looked down upon by Chinese analysts), is expected to land a rover on the moon by 2012. The space agency, if it can persuade Parliament to fund all its dreams, aims to put a man on the moon by 2020, followed by robotic missions to Mars, a nearby asteroid and the sun—an agenda even more ambitious than China's.
The Indian space agency is careful to defend the program as more than an ego competition with the Chinese. It argues that its space program has earned a return of $2 on every dollar invested by the government, according to Nair. For example, its remote sensing satellites, which map the Earth's surface at a resolution of close to one meter, have helped find well water in dry regions, saving the government's drill boring program $100 million. And, while only a few years ago Indian space officials ruled out manned missions as too expensive and of dubious scientific value, they now speak—just like the Chinese—of mapping the moon for deposits of aluminum, silicon, uranium and titanium, probably with an eye to lunar mining. "I don't think we're in any race as far as the space program is concerned," says Nair. "We have our own national priorities, and based on those priorities we try to concentrate on developments which will benefit the people."
Moon shots for the masses? "If you ask people [in the space agencies], they will never acknowledge there is a competition," says Pallava Bagla, the author of "Destination Moon," a book about India's moon mission. "But subliminally there is a definite race there." The two sides don't talk about it because, says the Stimson Center's Michael Krepon, "for Beijing, you don't want to put New Delhi on the same playing field. For New Delhi, you don't want to acknowledge anxiety." Krishnaswamy Kasturirangan, a member of Parliament and Nair's predecessor, says that in addition to luring Indian engineers from the high-paying IT divisions into astrophysics, the space program will "establish our credentials in the international community." It makes India a player.
The benefits of manned missions for the military are only somewhat clearer. Beijing's satellite shoot-down last year demonstrated the potential vulnerability of objects in space. Its space program—which is ultimately run by the Army—got its start when engineers took military rockets and stuck capsules on the tip. And despite Delhi's claims to the contrary, Western analysts suspect that booster technology developed for India's civilian space program is used by its military arm. But the quick way to strengthen military rockets is to fund them directly, not to fly moon missions. By the same token, ground-based and orbiting lasers would probably make better antisatellite weapons than missiles. "The U.S. military and the Russian military searched for years for good reasons to put military people in space and never found any," says John Logsdon, senior fellow at America's Smithsonian National Air and Space Museum.
Still, a space race is a risky way to boost national status: after all, a catastrophic accident while attempting merely to repeat this step for mankind would be a historic humiliation. But the risk is not without rewards. Successful space flight is a kind of national advertisement for satellites and, more broadly, quality control. "[China's] manned space program has gone a long way to proving to potential customers that their products are safe," says Theresa Hitchens of Washington's Center for Defense Information. In these days of global competition, that's a message both China and India desperately want to send.

It was 1961 and Hal Shevers was a flight instructor at Cincinnati's Lunken Airport. Hal, the Entrepreneur began selling supplies to his student pilots. His good idea has turned platinum for him? Many of us start a small business based on needs of the people we have around us. With Hal, the product was an air band radio.
When I first came to Cincinnati in 1963 with Lake Central Airlines, I remember that Sporty's was just getting started good. It was located in the terminal building where the Flight Depot now exists. Later, I recall Sporty's being located across from the Terminal on Wilmer Avenue at the corner of Airport Road. Sporty's existed in this location until 1990.
By this time Sporty's Academy (1987) had been started to develop aviation courses including videos for pilots. Sporty's wanted to teach pilots everything there was to know about flight from the very basics to the complex including Weather, Safety and Air Traffic Control. The Aircraft Owners and Pilots Association Air Safety Foundation had already been working with Hal to develop their their three-day ground schools so Hal was more than ready to step out with his own branding.
I started my own business in much the same way selling photo business cards to pilots during a 35.5 year airline load control agent career. See www.airpixphoto.com | aerospace |
https://next.tnwcdn.com/news/the-evolution-of-aircraft-flying-taxis-and-autonomous-passenger-drones | 2023-10-02T15:11:29 | s3://commoncrawl/crawl-data/CC-MAIN-2023-40/segments/1695233511000.99/warc/CC-MAIN-20231002132844-20231002162844-00501.warc.gz | 0.955 | 2,463 | CC-MAIN-2023-40 | webtext-fineweb__CC-MAIN-2023-40__0__261888943 | en | Since EHang unveiled what it claimed to be the very first drone capable of flying a person at the Consumer Electronics Show (CES) in 2016, there’s been a huge interest in air taxis, passenger drones, and eVTOL (electric vertical take-off and landing) aircraft.
So I’ve decided to look at the main players in this exciting space, to explore their progress, and their USP.
EHang’s has been hard at work to create a commercially viable autonomous eVTOL.
Their aircraft appears largely ready to go, but there’s not all that much technical knowledge available. What we do know is that EHang’s aircraft charges from 220V or 380V power supply in an hour — really slow compared to its competitors.
The company has flown their autonomous aircraft across three cities in South Korea in 2020, where it used sacks of rice to simulate passengers. They have also participated in high-rise fire fighting drills and completed pilot cargo flights in Estonia earlier this month.
They’ve announced the launch of their first unstaffed tourist flights in Zhaoqing, China, for 2021.
EHang has also started production at a new facility in Yunfu city, China.
Time to market: Unknown, but I suspect we’ll see something in the next three years.
Funding: $92 million
Verdict: Even if EHang flew in China only, they’d have enough business to thrive. They have a highly compelling product and great marketing, although there are a few logistical challenges. For example, the slow battery charge is a downside — hopefully, they have plans to scale to a swappable battery.
Aeromobil has created what most of us traditionally envision when we think of a flying taxi – a vehicle that’s a car and plane combined and looks like something out of a James Bond movie. Yep, you get to fly a car!
In 2010, the company became a reality, and it has since completed flight testing of three functional prototypes (including two and four-seaters and eVTOL aircraft) with the firm’s first flight in 2014.
Its latest version includes over 300,000 hours of engineering.
AeroMobil achieved key flight testing targets in March this year for its two-seater 4.0 flying car. It delivers a flying range of up to 740 km and a driving range of up to 1000 km.
However, the aircar is not exactly green. It is powered by a hybrid propulsion system with a turbocharged internal combustion engine — yep, not that different from a car.
Time to market:
- Two-seater: 2023
- Four-seater: 2025
Funding: $31.7 million
Verdict: This is one of the most accessible aircraft with the apparent benefits of parking. However, its environmental benefits aren’t great — I’m waiting to see the eVTOL, which is yet to be revealed.
Volocopter is developing the fully electric eVTOL aircraft. Called the Volocopter VoloCity, it’s designed for two seats and hand luggage. It flies with nine rechargeable batteries powering 18 motors.
The company began in 2011 and piloted their first 90-second eVOTL that year. Since then, they’ve completed over 1000 test flights.
Technicians can supply the aircraft with a newly maintained and charged battery shortly after landing. Aircraft are ready for take-off again in a matter of minutes. They can fly with range of 35km and at a speed of 35km/h.
Volocopter is also working on a four-seater option. Plus, an electric utility drone called “VoloDrone” is currently under development. It can carry 200kg for 40km. The VoloDrone demonstrator performed its first flight in October 2019.
Apart from that, Volocopter is constructing a VoloPort (landing and launch pad) prototype in Singapore with interest in routes in Singapore and Paris.
Additionally, Volocopter recently partnered with Urban Movement Labs (UML) to explore potential routes in Los Angel.
Optimistically, Volocopter opened a thousand $352 tickets to the public in 2020 for a 10% deposit reservation. Predictably, they sold out, the fine print stipulating a maximum passenger weight of 85kg — put down that chocolate bar!
Time to market: 2022-4
Funding: $369.2 million
Verdict: Volocopter is a true innovator. After so many years in stealth mode, the company must have been fuming at EHang’s 2016 CES announcement. I think they’re wise to be focused on freight — assuming they can scale their efforts. The fast battery swapover is a strong selling point.
Lilium was founded in 2015. Their creation is the eVOTL five-seater Lilium jet. Until now, it’s capable of journeys of up to 250km in one hour on a single charge (far above its competitors).
Among its competitive advantages is its design: two sets of wings translate into a higher efficiency than rotors. The company is also creating a seven-seat version capable of faster, longer flights.
Lilium has an agreement with Köln Bonn Airport and Düsseldorf Airport and is sourcing pilots and training through Lufthansa Aviation Training.
Time to market: 2024 operating in multiple regions in 2025
Funding: $374 million
Verdict: Their innovative design is impressive, and the company’s partnerships mean great access to the European market.
Kitty Hawk (USA)
Kitty Hawk is one of the strangest flying vehicles. It launched in 2015 with an aircraft called Flyer, which required no license and only minutes to learn to fly. The company shared last year that they were winding down the Flyer after five years, explaining:
More than 75 people flew Flyer. We proved to ourselves that people could safely operate Flyer — and become a pilot — with less than two hours of training. On a single day, we trained 50 new novice Flyer pilots without aviation licenses. Overall, we conducted over 25,000 successful flights with our Flyer fleet. And most importantly, those who flew Flyer thought the experience was “magical.” The feeling of being inside a human drone is hard to describe. For those of us who flew it, it has changed our perspective on the power of flying forever.
What a vision!
Today Kitty Hawk focuses on its other creation, the one-person Heaviside plane, which has a range of 160km with speeds of up to 260km/h. Heaviside uses less than half the energy per kilometer of travel than a Tesla Model S at faster speeds. Further, it can take off and land in a 9-meter x 9-meter unpaved area.
Time to market: Unknown, but keep an eye out for an acquistion
Funding: $1 million
Verdict: It would be easy to dismiss Kitty Hawk, but there are definitely military applications that make them ripe for acquisition. In July, the company announced airworthiness approval by the US Air Force. With this award, the Heaviside aircraft can enter its next phase of flight testing under the Air Force direction. This gives them a lot of infrastructure not available to its competitors.
If you cheer for the underdog, this is the company to watch. Would I fly one? Fuck, yes.
Joby Aviation (USA)
Joby Aviation was founded in 2009 and has largely operated in stealth. What we do know is that they’ve created a full-sized five-seat aircraft with six tilting rotors and a V-shaped double tail. According to Joby, it flies at up to 322km/h at a 240km range per battery charge.
They’ve been in development with NASA for ten years, and in 2020, Joby became the first eVTOL company to receive airworthiness approval from the US Air Force. This provides access to government testing facilities.
In the same year, they acquired Uber’s Elevate division, giving them a huge rideshare advantage.
Time to market: 2024
Funding: $1.6 billion
Verdict: Ok, we don’t know all that much about the aircraft, but they have the most (publicly disclosed funds) and access to NASA and US Air Force R&D. Their purchase of Elevate gives them a plan for infrastructure
We know little about Archer. However, they’re building a two-seater autonomous eVTOL aircraft designed for a 96km range at a speed of up to 240km/h. Their focus is short-haul journeys — their partnership with United Airlines makes ferrying people between cities and airports a likely goal.
The company recently partnered with an operator of thousands of parking garages with an expansive network that covers more than 70% of the US.
Time to market: 2024 for US consumer operations
Funding: $55.7 million
Verdict: Archer is a company where I’d like to learn more. Short-haul trips arguably offer the least value for your buck for passengers, so I’d be interested to see how they could successfully scale.
Auto OEMs are snapping at the heels of tomorrow’s aircraft
While I’ve detailed some of the key players in the race for aerial vehicles, plenty of auto OEMs have a big interest in eVTOL and autonomous aircraft. 2019 saw Aston Martin, release a “vision concept.” Boeing created a prototype that we haven’t heard much about since it crashed on its fifth flight in 2019.
General Motors released a video of a single-passenger eVTOL drone at CES 2020 under the Cadillac brand. It claims to be fully autonomous, powered by a 90W motor, a GM Ultium battery pack, and four pairs of rotors. That’s about all we know, though.
Hyundai had a partnership to develop Uber Air Taxis, but their involvement is questionable as the company sold off its flying taxi service to Joby later that year.
Let’s face it, at worst, a big fancy prototype (or with even less effort a video simulation) impresses your competitors. At best, we’ll see skills and technical knowledge converge speed up innovation?
So who’s winning the race?
I’m placing my bets on Joby. They have the most money (excluding recently SPACs by Lilium and Archer). The NASA and US airforce involvement gives them access to a vast amount of R&D and skilled professionals. Also, Uber Elevate may prove to be hugely beneficial.
But at any rate, I would say the start dates of 2023-24 are wildly optimistic due to COVID factory lockdowns and the corresponding supply chain and materials shortages. The first ‘passengers’ will, I believe, be limited to trained pilots, and aircraft will not be autonomous — at best, it will have some remote control and autonomous functions. But before this is possible, the companies need to iron out the infrastructure, the legalities, and convince the public of their safety.

It was decided that a “glitch” (malfunction) to a direct current switching unit caused the problem.
The direct current switching unit controls the distribution of power from the solar array to various hardware locations such as the battery systems. Two communication systems, some science facilities, control moment gyroscope # 2, various lights, and a few heating units were affected by the power loss. As designed, redundant systems took over for the primary systems while the matter was being investigated.
The P4 solar array electrical system is part of the P3/P4 truss assembly on the space station. Together, the P3 and P4 (P stands for Port side) segments contain a pair of solar arrays, a radiator, and a rotary joint. The P3/P4 truss assembly was installed during the STS-115 mission by the Space Shuttle Atlantis crew, which was launched on September 9, 2006.
Within twenty-four hours, mission ground controllers had restored power to almost all the affected systems and equipment. At that time, they were still trying to determine why the initial glitch occurred, and if it was only an isolated incident.
NASA personnel indicated that the ISS crewmembers were in no immediate danger from the power failure. The crewmembers aboard the International Space Station (ISS) at the time of the incident are U.S. commander Michael Lopez-Alegria, Russian flight engineer Mikhail Tyurin, and U.S. flight engineer Sunita Williams.
As of February 8, 2007, the following is a listing of the major statistics on the International Space Station: https://spaceflight.nasa.gov/station/isstodate.html.

A few days ago I read in the newspapers that Sri Lanka opened another international airport (RML) in Ratmalana on March 27th. There was also a picture of the arrival of the first aircraft, a Maldivian Airline Dash-8, 50-seat twin-turboprop that flew from Velana Airport, Hululle, to Ratmalana. The plane was greeted by water cannon arches created by the airport fire department’s fire trucks. Kandyan dancers were also present, as well as a VVIP contingent to celebrate the inauguration of the new international airport. Of course, the fanfare of the day must have cost millions; that’s what the newspapers said.
Ratmalana Airport (RML) has a remarkable history. It came into being as a 600 square foot cleared lawn, which had galvanized roof sheds, on the side where the terminal was located. It was 1935 when the first plane, a Puss Moth piloted by Flt/Lt Tyndale-Biscoe, landed on level grass, making it a sweet opening for the new airport. There was no marked runway, only a black and white striped windsock that stood like a sentry to tell the pilot which direction to land or take off.
The official opening of the airport took place on February 28, 1938 when a Tata Airways mail plane, a Waco, took off from Ratmalana.
Between Tyndale-Biscoe’s Puss Moth and the Tata Airways mail plane, there were people learning to fly on the Ratmalana Lawn, which included expats as well as locals. They were the airmen of the Ratmalana Flying Club.
Then came the RAF, followed by commercial aircraft and Ratmalana had its heyday. Leading airlines such as TWA, BOAC and KLM have landed and taken off from Ratmalana. They flew their Lockheed Constellations, de Havilland Comets and DC-4 Skymasters using Ratmalana as a ‘pit stop’ to operate their long haul flights. Then, in 1948, the national carrier, Air Ceylon, took over Ratmalana as its base of operation.
I saw Ratmalana from the first day I flew a small plane as a rookie pilot. I learned to fly there, take off and land on the grass runway. I flew my first commercial flight on a DC-3 from Ratmalana and trained a host of student pilots at Ratmalana. Yes, I have fond memories and precious moments of flying airplanes from that wonderful old airstrip that laid the foundation for my flying career. The memory is filled with admiration, not only for me but for all those who have had a connection with this old brand airfield.
So what are they doing in Ratmalana? Bad enough, we have Mattala’s magnificent error. Do we need another fiasco contributing to our country’s financial difficulties? Mattala is known as the emptiest airport in the world. Are we also trying to win the second prize with Ratmalana?
Ratmalana can be a very good airport to accommodate domestic flights. It is also good to operate air force planes which serve all airfields in Sri Lanka. Ratmalana has served his time and served Sri Lanka faithfully and must now make way for Katunayake and Mattala to handle international arrivals and departures. RML has ONLY a 1400 meter runway which cannot take even the smallest of passenger jets, a Boeing 737 or an Airbus 320. How do you fly international or for that matter even regional from such a short runway? Extending the length is not financially viable as either you have to send the Galle Road underground or go towards Diyawanna Oya on the other side.
Yes, maybe it can accommodate a business jet, but you have to remember that a business jet does not bring many passengers. They are used by the rich and famous and to have 50 passengers in the airport terminal would require at least 10 business jets. This poses a parking problem. Someone certainly didn’t count their marbles when they decided to play this game.
Yes, I saw the large paved access road to the new RML. Almost like the four lane highway we have in Mattala. Ratmalana, too, would be another “all hats and no cattle” story. Someone whispered that it cost 200 million to build the road and renovate the terminal. Maybe whoever was in charge of the project took that money and did something to improve the navigation facilities at the Ratmalana track. This is an intransigent safety factor that has been totally ignored.
On March 27, 2022, when the first international flight landed, no landing aids were functioning except for a set of Precision Approach Path Indicators (PAPI) lights on the north/east side of Runway 22 and nothing on track 04.
The PAPI lights will help a pilot to adjust his final approach course, but it does not help him in any way to make a ‘Let-Down’ instrument to locate the runway in bad weather.
Let’s take a look at this history of landing aids. On December 11, 2014, a Sri Lankan Air Force Antonov aircraft flew from Katunayake to Ratmalana in the morning. Visibility was marginal with mist and low cloud and the aircraft on approach struck the ground 10 miles short of the runway threshold and crashed. Of course, the voices that had power blamed the pilots. No one mentioned that Ratmalana airport at that time had no landing aids. No ILS, no VOR/DME and the non-directional beacon was unusable. The crash was said to be pilot error. But I don’t think that’s the right conclusion. Pilot error may not be pilot error. There is a one mile difference between pilot error and pilot error. (sorry I have no space to explain) Sdn/Ldr Abeywardena and Flt/Lt Jayatunge, plus three others died in vain, simply because there were no landing aids at Ratmalana on that fateful day in December. If there had been at least one good working landing aid, this unfortunate accident could have been avoided. And today in 2022, we have the same runway classified as an international airport. Can you believe the same landing aids that weren’t there in 2014 still aren’t there in 2022? I’m not whistling Dixie here. I checked Ratmalana’s NOTAM on March 27, 2022. NO LANDING AID FOR RUNWAY. It is sure that providence is tempting. Too bad, when they were thinking of turning Ratmalana into an international airport, they completely forgot why the Air Force Antonov had come down to Hokandara.
Who is making these colossal mistakes of opening new international airports without assessing safety or researching and confirming commercialization? Only Diyawanna Oya would do that! And Yahapalanaya also was guilty of the same mortal sin. Let’s not forget that it was the Yahapalana brothers who opened Jaffna International Airport with a 1400 meter runway and brought in Alliance Air ATR -72-600 twin-turboprop planes that were to operate a daily service Chennai- Jaffna-Chennai. What happened to these promised flights is the same thing that happened to the hordes that were to come to Mattala.
As for Ratmalana, the Maldivian operator has already made the first flight with a flamboyant arrival ceremony that cost millions. Then they turned around and canceled the next flights for lack of passengers. No doubt there would have been some brilliant planning and marketing to achieve such a mesmerizing result.
Let’s be realistic, Mr. Diyawanna Oya. We and the whole world have been hit by Covid. As we started to raise our heads, we had the nasty dollar pandemic. Today, the inhabitants of our beautiful paradise are suffering from multiple calamities without even a mirage in sight. And we are opening an international airport that will only have one propeller plane from Male at best. That too, only if they can find passengers.
Of course, business jets would fight to come – That’s the hope? If wishes were horses, beggars would ride!
We have Katunayake, Mattala, Jaffna and now Ratmalana designated as international airports. Don’t do the same in Batticaloa too! Leave that to the next lot who will win the Diyawanna Oya musical chairs and get their seats to serve the nation. Let them open Batticaloa International Airport. They too may want to jingle coins in their pockets.
As for the aviation responses, let me be serious. We are definitely coming to the air traffic capacity limits in Katunayaka. Maybe we’ve already moved past that and are operating on borrowed time and have pleaded tolerances. We need a second parallel track of 2500 meters in Katunayake. This length is adequate for small passenger jets such as A320s and Boeing 737s. If a dual runway concept can be achieved, authorities can use Katunayake as an international hub for all international flights (including airliners). business) who will arrive in Sri Lanka. Then we can use our so called international airports – Ratmalana and Jaffna as well as all small local airfields such as Ampara, Batticaloa, China Bay, Weerawila, Anuradhapura, Minneriya, Sigiriya and Katukurunda for twin engine propeller planes to effectively operate and manage internal flight service.
As for Mattala, the authorities have been trying for years to sell or rent it without success. Why not give it to the Air Force? Give him the lock, the stock and the barrel and make them Mattala’s guardians. They can certainly take care of all the movements of civil aircraft and share the airfield with them. There’s room for both and more.
Whatever you do, Mr. Diyawanna Oya, don’t make fun of Ratmalana; she deserves better. | aerospace |

Published February 7, 2022
Students in UB’s Nanosatellite Laboratory will compete for a new mission this spring, as part of the U.S. Air Force Research Laboratory’s University Nanosatellite Program (UNP).
Named the Polarimetric Observer Light Analyzing Research (POLAR) mission, the students will investigate space debris, a growing issue in Earth’s orbit.
The University at Buffalo, which partnered with Rochester Institute of Technology, was one of 10 schools chosen to participate in the two-year UNP partnership to design, fabricate and test small satellites.
“The POLAR mission will provide details on the material makeup of debris,” says John Crassidis, Samuel P. Capen Chair Professor in the Department of Mechanical and Aerospace Engineering and advisor to the UB Nanosatellite Lab (UBNL). “This will allow us to develop more detailed models to better predict the location of debris as the travel in orbit, which will lead better calculations to help avoid collisions with other objects.”
The UNP program aims to not only do novel research that can contribute to the potential of small satellites, but to grow the educational institution to space industry pipeline.
“Throughout the two-year program, student participants will design, fabricate, and test a small satellite,” says Col. Eric Felt, director of the AFRL Space Vehicles Directorate. “We also hope to foster research in enabling technologies, and the design of experiments that can be performed by small satellites in orbit. We are helping to develop the pipeline for the burgeoning space industry.”
For students in the School of Engineering and Applied Sciences, the opportunity to work on a satellite that will launch into space is unparalleled, as are the connections and hands-on experience they gain.
“What makes our project unique is that the main goal of our mission is not only to detect resident space objects, but also determine their material makeup,” says Chet Knoer, a PhD student in aerospace engineering and the project’s graduate student supervisor.
Knoer has been involved in UBNL since coming to UB to earn an undergraduate degree in aerospace engineering. They went on to a master’s in material design innovation and are starting on their PhD this semester.
Knoer says, “I'm excited about so many things on the POLAR project, but mainly that it is a way for the lab to take what we have learned on previous missions and put it to use on this one. For the undergraduates, this is an opportunity to start fresh. For me, it’s a chance to pass on the systems engineering knowledge I gained from working outside of the classroom.”
“I am looking forward to having the chance to do the framing of a project rather than working within the framework that someone else had created,” says Charles Dicus, a junior engineering science major and POLAR’s chief engineer.
For the last few years, he worked on the Ground Systems Team for the GLint Analyzing Data Observation Satellite (GLADOS) mission, which ran from 2011 to 2020 and was UBNL’s longest-running project. “I relish the opportunity to help make important decisions – and do it in such a way that everyone who contributes throughout the duration of the project can understand why and how they were made, and how they fit into the general process.”
POLAR, like all projects in the UBNL, will rely entirely on the dedication of students. Knoer says, “We really need volunteers for this project to be successful, and we encourage students with all levels of experience (even no experience) to join. We provide training, and we are a super fun lab with students from a huge range of backgrounds.”
The Air Force Research Laboratory (AFRL) is the primary scientific research and development center for the Department of the Air Force. AFRL plays an integral role in leading the discovery, development, and integration of affordable warfighting technologies for our air, space, and cyberspace force. With a workforce of more than 11,500 across nine technology areas and 40 other operations across the globe, AFRL provides a diverse portfolio of science and technology ranging from fundamental to advanced research and technology development.

Photo 3 of 5
Pocket DroneRaised: $929,212
Shut Down: Summer 2015
"The year 2014 is going to be the 'Year of the Drone'," proclaimed the Kickstarter campaign page for this "personal flying robot." Well, that was true, 2014 was a great year for drones. But not so much for Pocket Drone, a much-anticipated, lightweight multicopter powerful enough to carry a "high quality action camera" but small enough to "fold up smaller than a 7in tablet."
The drone was said to have the "longest flight time of any multicopter under $500." Aimed at photographers and hobbyists, the Pocket Drone looked set to bring affordable, high-quality drone photography to the masses. Autopilot and "follow me" modes completed the picture of a drone that was almost too good to be true.
AirDroids, the company behind the project, became victims of their own success. The Kickstarter project resulted in 20 times more orders than they had anticipated, and AirDroids found it difficult to scale up the manufacturing process.
Units were sent out to some backers, and the company founders even took on $100,000 of personal debt. But that wasn't enough to prevent AirDroids from folding in the summer of 2015. | aerospace |

When I was seven years old, and crazy for space, I had memorized the names of all the astronauts from Apollo 7 through 11 and built models of the lunar module in Revell’s plastic and Gulf Oil’s cardboard kits. I also had quite the collection of Major Matt Mason action figures and (IIRC) one of the child-sized plastic space helmets that were all the rage among budding astro-nerds.
This obsession began, near as I recall, with seeing 2001: A space odyssey the year before, after which I vowed to become an astronaut or die on the launchpad. I couldn’t then, and can’t now, explain why the space program took such a firm grasp on my young mind: aesthetics? Novelty? Simple escapism? Perhaps all of these, perhaps none. All I know was that I wanted to go.
As we celebrate in two days the 50th anniversary of that historic footprint, we humans can claim a couple of space stations (ISS and Mir, and once-upon-a-time Skylab) and telescopes (Hubble, Kepler, Spitzer, Gaia); countless lunar, solar, asteroid, comet, planetary and space probes, including two of the latter which have now left the solar system; dozens of (if now defunct) shuttle flights; various commercial endeavors; and blackboard proposals for orbital hotels, lunar bases, and manned Mars missions.
But back to the moonwalk. The next thing I remember is my mom gently shaking me awake. “Honey, you missed it,” she said. I don’t have many regrets, but sleeping through that “one giant leap” is at the top of that short list.
Space travel has almost become passe — “all the regularity of the crosstown bus,” as Harlan Ellison once wrote. But for anyone who remembers astronautics pre-empting regular broadcasts on all three TV networks, it will always be one of humanity’s greatest continuing adventures. (Even if some of us sleep through parts of it.) | aerospace |

NASA’s Perseverance rover touched down on Mars yesterday, marking the success of their latest mission to the red planet. In a livestream of the landing, employees at NASA can be seen overjoyed by the touchdown.
They played Yungblud’s cover of the iconic David Bowie song ‘Life on Mars’ in celebration of the mission, which can be heard in the footage. Apparently, NASA cleared the idea with Yungblud’s manager before the mission started. When the artist found out about the plans, he thought his manager was joking.
“I love space so I am here for it. I remember my 23-year-old manager rings me on the phone. It was late cos he’s in LA and it must have been midnight cos I’d had a couple of beers, so I was already kind of out there.
“He’s like, ‘Yo, I just got off the phone with NASA’. I’m like, ‘Alright, yeah cool, what’s it about? You leaving me to go be an astronaut,’” the artist said in an interview with the BBC.
When his manager went on to tell him about the space agency’s plans, Yungblud said he thought his manager had gone mad.
After he heard his song play at NASA, he said he was in complete awe of the honour.
“It’s completely unfathomable. Someone needs to slap me so I’ll wake up,” he added.
Yungblud took to Instagram when the song played and by the looks of it, he truly was beyond words.

Our plane flew over Cape Canaveral and we saw the SpaceX Falcon 9 launch. We witnessed a once in a lifetime event.
Nelito’s TikTok post has received more than 16,000 comments since Friday. Below are some of them:
- This is what it means to be at the right time in the right place;
- Wow, what did they look like;
- I can’t believe they fired a rocket when the plane was flying so close;
- It is shocking how little time it took for the rocket to rise above the aircraft;
- Now I will look out the window at every opportunity;
- I thought seeing a rocket in the sky was cool. But it’s just epic.
Other commentators sympathized with those on the other side of the plane.

24 October 2006
UCL scientists are enabling the Queen and 1,000 sixth formers to take a three-dimensional virtual flight over the surface of Mars on 24 October 2006.
The UCL scientists and engineers have teamed up with the Open University and Imperial College London to present their 'Rough Guide to Mars' exhibit at Buckingham Palace's Science Day, part of the Queen's 80th birthday celebrations.
The team originally created the exhibit for the Royal Society's Summer Exhibition in July 2006. Using 3D images and research from the European Space Agency's Mars Express Mission, currently orbiting the red planet, visitors will be able to discover the latest information about our planetary neighbour in unprecedented realistic detail.
UCL is providing a 'Geowall' consisting of a large polarised screen and two projectors held on a three-legged gantry. The Geowall will enable Virtual Reality tours to four areas on the Martian surface using unique large area 3D models and terrain-corrected image mosaics created at UCL. A new 3D animation loop has also been created.
Mars Express Co-Investigator Professor Jan-Peter Muller (UCL Mullard Space Science Laboratory), said: "We will present for the first time 3D guided tours of another planetary surface which allow the visitor to decide where they wish to land and explore the surface."
Located in the State Ballroom, the out-of-this-world experience will also consist of a large graphic pop-up display, a Mars meteorite, and a scale model of the Mars Express craft. Some 1,000 sixth form students and their teachers will visit the exhibition during the day followed by distinguished scientists and members of the Royal family.
For those not attending the Science Day, virtual flyovers can also be seen on the team's 'Life on Mars' website, along with the latest news from Mars Express.
Europe's first-ever space mission to another planet entered the orbit of Mars successfully on Christmas Day 2003, and since January 2004 the high resolution stereo camera on board has been taking a massive number of detailed surface images.
The 3D information means that, for the first time, scientists are able to make geological and geomorphological measurements just as geologists do on the Earth. The images also provide a wealth of information on past climate and water, as well as the relative ages of the surface from crater measurements on Mars, the evolution of volcanism, potential resources, characteristics of present and future landing sites, and observations of Mars' two tiny moons, Phobos and Deimos. With 3D images received from Mars Express, the collaborative team of scientists discovered a frozen sea near the Martian equator which was reported in Nature in March 2005. | aerospace |

Of the schools studied in the report most said that recruiting or retaining flight instructors was a challenge and that being able to keep flight instructors on staff was the greatest challenge their flight schools faced in being able to produce more pilots in order to meet the increasing demand.
Some of the aviation universities mentioned in the study say that in the current employment market that they are unable to recruit and retain enough flight instructors to teach all of the pilot students that their programs could normally accommodate.
Even those schools that are able to stay fully staffed are having trouble with the quality of their training as high instructor turnover routinely subjects students to new flight instructors and reduces training continuity.
The schools interviewed said that flight instructor turnover is expected as most pilots do not pursue instructing as a career goal. However, they continued “that in recent years, airline industry growth, increasing pilot retirements, and other factors previously discussed have caused commercial airlines to accelerate pilot recruitment, ultimately causing pilots to move through the instructor ranks more quickly.”
Complicating the issue further is the requirement that to train a new flight instructor a current instructor must have two years of experience. Flight instructors usually get enough experience to qualify for their Airline Transport Pilot Rating (ATP) before two years. Flight schools ability to train new instructors is eroding.
Typical Pilot Career Progression
The typical path for a pilot to work their way up through the career is first as a flight instructor or other entry level position such as pipeline patrol flying. After earning enough time to earn their Airline Transport Pilot rating pilots then move on to Regional Airlines. They then gain experience at the Regional Airlines before moving on to a Major Airline.
Most career minded pilots seek to move up through the career rungs as quick as possible so that they can start accruing seniority at the major airlines, which is the all important number that dictates pay and quality of life for airline pilots.
When there’s pilot shortages they typically become noticeable to employers at the bottom of the career progression ladder before employers further up the chain notice. For major airlines to notice a shortage the supply of pilots would need be dire.
The Cost of Flight Training is a Challenge For Some Flight Schools When It Comes to Attracting and Retaining Students
Of the flight schools included in the study most said that they have seen a general increase in interest from prospective pilot students over the last 5 years, likely from improvements in the profession’s pay and improving career path. But nearly all the schools said that the cost of training was a major issue when it came to attracting and retaining the new students.
Flight training costs vary considerably but currently range between a total approximate cost of $50,000 to $81,000. Some of the schools said that it is not possible to appreciably reduce these costs as flight training is inherently expensive.
Some schools are attempting to find solutions to help flight students pay for school by raising money for departmental scholarships. One school mentioned that they’ve approached some major and regional airlines to see if they would make scholarships and school subsidies available.
New Pilot Hiring Programs Further Threaten Flight Schools
Also causing potential additional issues for flight school’s ability to attract and retain flight instructors is aviation employers creating new and unique employment opportunities to help ensure access to more pilots. This will give pilots just entering the profession additional job options to consider and alternative paths for their first pilot jobs.
There Are Not Easy Solutions for Flight Schools
Many would assume that raising pay would be an easy solution to attract and retain employees. However, flight schools are often on par with regional airlines already. The main challenge they face is the career progression most pilots seek.
The easiest solution would be another downturn in what is often a very cyclical industry. This would reduce the demand for pilots and would flood the market with pilots being laid-off from airlines. Most industry experts do not want this and also consider it unlikely with the pilot shortage projected to continue for decades.
Some schools have partnered with regional airlines and have created arrangements that allow pilots to accrue seniority with an airline while still flight instructing. Other schools offer free or reduced cost advanced training to instructors in return for agreements from the pilots to stick around longer. One school is reported trying to seek an arrangement with a regional airline whereby the airline would not hire their instructors.
Many of the schools have put significant resources into recruitment efforts, with some now seeking non-traditional applicants such retired pilots, or other pilots who may not meet medical requirements to work for the airlines.
At least 6 regional airline now offer cadet programs which provide incentive for graduates from partnered schools to remain and instruct at that school until they meet minimum requirements to work for the airline. Students who sign up for the cadet program with an airline agree to provisional employment with the airline. In return the regional airlines may provide health benefits, bonus pay, or tuition reimbursement. The schools have said the cadet programs are not popular as most flight students prefer to not commit to a single airline.
Some collegiate aviation programs are considering making obtaining a flight instructor license a requirement to graduate in hopes of increasing the available pool of instructors.

Sikorsky Aircraft Corp. today congratulated AeroVelo Inc. in Toronto, Canada, for a flight that has won the AHS Igor I. Sikorsky Human Powered Helicopter Competition, a feat that brings a Sikorsky-sponsored prize of $250,000. Sikorsky is a subsidiary of United Technologies Corp.. The American Helicopter Society (AHS) International and Sikorsky Aircraft presented the award at a special ceremony today at The Soccer Centre in Vaughan, Ontario where the record-breaking flight was conducted.
The Toronto-based AeroVelo (derived from the word aerodynamic and the French term for bicycle) team is led by Dr. Todd Reichert, pilot and chief engineer, and Cameron Robertson, co-chief engineer. The team, comprised largely of students at the University of Toronto, beat the 33-year old challenge last month, flying its "Atlas" above 3 meters (9.8 feet) and hovering for approximately 64 seconds. Officials from the AHS verified the flight data over the past few weeks and concluded it meets all of the criteria necessary to win the competition.
The AHS first issued the human-powered flight challenge in 1980, with an initial prize of $10,000. Since then, many teams have attempted to meet the objective of creating a helicopter that could rise three meters and hover over a 10-meter-by-10-meter box for one minute using only human-generated power.
"When Sikorsky increased the prize to a quarter-million dollars in May 2009, many people were skeptical and felt the challenge was impossible," said Mark Miller, Vice President, Research and Engineering for Sikorsky. "And that is exactly why we raised the stakes – to encourage creative thinkers to prove that what is considered impossible is often proven to be possible. That has been the philosophy of Sikorsky Aircraft since the founding of our company by aviation pioneer Igor Sikorsky 90 years ago. Congratulations to the AeroVelo team!"
"This is an incredible accomplishment," said Mike Hirschberg, executive director of AHS International. "For a third of a century, the AHS Sikorsky Prize has eluded the best minds and technology available. The technological and theoretical advancements achieved in pursuit of our challenge have been astounding."
"The past two years of the competition have been very exciting, with several teams racing to best one another, and more flights than the previous 30 years combined," said Benjamin Hein, Chairman of the AHS Igor I. Sikorsky Human-Powered Helicopter Committee and a senior engineer at Sikorsky Aircraft.
More than 20 human-powered helicopters have been designed and built since the competition began, though only a handful have gotten off the ground. Recent teams contending for the prize include the University of Maryland's Gamera and the California Polytechnic State University team with its Upturn aircraft. The most successful competitors from the 1980's and 1990's included a student team at California Polytechnic State University with its DaVinci III helicopter and the team at Nihon University flying the Yuri I, which previously held the world HPH endurance record at 19.5 seconds.
AeroVelo's Atlas vehicle is the largest human-powered helicopter to have flown, and the first in Canada, with each of its four rotors measuring nearly 70 feet. The airframe is constructed of very light carbon tube and polymer weighing only 115 lb, with a highly modified bicycle frame pedaled by the pilot. It first flew in August 2012. | aerospace |

20th May 2015
Marshall Aerospace and Defence Group’s engineering and integration services result in the rapid reconfiguration of two A330s for TAP Portugal.
In July 2013, TAP, Portugal’s leading airline, approached Marshall Aerospace and Defence Group to upgrade two A330s the operator was purchasing in order to increase its long range fleet. The upgrade was to include a cabin reconfiguration (to a standard TAP layout to bring them in line with the operator’s existing A330s already serving long-haul routes), new seating for both Economy and Business Class, a new In-Flight Entertainment System (IFE) and a Lower Deck Mobile Crew Rest (LD-MCR).
However, the upgrade timescales were exceptionally tight as the aircraft were going to be operated by another airline until the end of 2013 but TAP wanted both upgraded and in service by mid-2014.
TAP’s selection of Marshall was based on how well the company had project managed, engineered and integrated a four-aircraft (Airbus A340) cabin upgrade programme during 2012, which also had time-sensitive requirements. This gave TAP great confidence.
For the A330s upgrade, Marshall, upon contract award in October took on project management and engineering roles, giving immediate priority to ordering long lead-time equipment and addressing some of the more challenging integration issues. For instance, the LD-MCR, which can accommodate up to seven crew members, was particularly challenging as this unit is selected as an option when an aircraft is ordered from new (i.e. built-to-order). It occupies space in the cargo hold so, as a retrofit, required comprehensive structural changes to the airframe including the rerouting of cables and hydraulic lines. The LD-MCR also needed integrating with the aircraft’s electrical, cabin air distribution, smoke detection and alarm systems.
As for the IFE, the previous seat-back system was replaced with a new Panasonic Avionics eXLite one. It too has seat-back screens, the installation of which was relatively easy for Economy. For Business class, the seats and centre pedestals were modified by Marshall; and the company also had the responsibility of testing and re-certifying the seats, which involved sled acceleration tests to ensure they met Head Impact Criteria (HIC).
Marshall supplied approved modification kits to TAP Maintenance and Engineering, in Lisbon, and the installation of the upgrade commenced in the spring of 2014 with the support of Marshall on-site Design Engineers. The Marshall A330 modification was approved by European Aviation Safety Agency (EASA) Supplemental Type Certificate (STC), allowing return to service, and Federal Aviation Administration (FAA) bilateral approval is currently being applied for in support of US-based supplier interests and any later aircraft re-sale.
Although a challenging project, the upgrade of the first aircraft only took 92 days to complete. The second, only 52. Post modification and certification, the first aircraft was released to service on 25th July 2014; approximately 10 months after project inception, and several months less than the industry norm. | aerospace |

American Forces Press Service
PETERSON AIR FORCE BASE, Colo. — Air Force officials began a two-week phased opening April 26 of access to social media sites Air Force-wide.
Pacific Air Forces bases gained access to social media sites earlier in April, serving as the test-bed prior to the Air Force-wide initiative.
Air Force Space Command, Air Education and Training Command and Air Mobility Command bases will begin getting access to social media sites April 26. Air Combat Command, Air Force Reserve Command, Air Force Materiel Command, Air Force Global Strike Command, Air Force Special Operations Command and United States Air Forces in Europe will get access beginning May 1. During the final phase, Air National Guard bases will get access beginning Thursday.
It will take up to five business days to open up every base in each major command because technicians in the Integrated Network Operations and Security Centers responsible for opening social media access must account for the different major command network infrastructures. They also must allow members of the Air Force Computer Emergency Response Team to provide required services to each MAJCOM as they are granted access.
“Twenty-Fourth Air Force (officials) determined the best way to implement access to Internet-based capabilities was to follow the standard practice of allowing the 624th Operations Center, working in conjunction with the INOSCs, to determine who gets the upgrade first based on mission requirements,” said Brig. Gen. David B. Warner, AFSPC communications and information director and chief information officer. “The INOSCs have the most in-depth knowledge of the network infrastructures within each MAJCOM and thus can initiate changes in the most efficient way possible.
“Due to the importance of allowing access to more Internet-based capabilities for communication and collaboration, we are working to strike a balance between maintaining a safe and tightly controlled network while allowing airmen to have the access they need to get information and conduct business,” Warner continued. “We are diligently working with communications and information experts at 24th Air Force and the INOSCs to assure the mission, while ensuring a standardized roll-out and maintaining the appropriate level of security.”
Providing access to social media sites from Air Force government computers meets the intent of Department of Defense Directive-Type Memorandum 09-026 — Responsible and Effective Use of Internet-based Capabilities, issued Feb. 25.
“As we leverage these new technologies, it is imperative that all Air Force personnel practice safe online activity to protect the network,” said Gen. C. Robert Kehler, Air Force Space Command commander. “The Air Force views the use of social media sites as a positive way to communicate and conduct business. Social media and other emerging technologies provide an increasingly important means of communication and collaboration. Providing more open access will allow the Air Force to communicate more effectively to all Air Force personnel, their families and external audiences.”
Various Air Force and DOD regulations provide guidance for airmen using social media on government networks. Personal use of social media sites must be of reasonable duration and frequency that have been approved by supervisors and do not adversely affect performance of official duties, overburden systems or reflect adversely on the Air Force. | aerospace |

Russian authorities reported on Friday that their air defense systems successfully intercepted drones approaching three of the nation’s western regions. Concurrently, satellite imagery suggests that a significant drone onslaught earlier in the week resulted in the destruction of at least two Ilyushin Il-76 military transport planes at a Russian airbase.
According to regional governors, defense systems thwarted three drones in the Kursk, Belgorod, and Moscow regions.
Although Moscow temporarily suspended flights at its airports, Russian authorities confirmed that no major damage or injuries occurred.
These drones, directed at targets within Russia and attributed to Ukraine by Moscow, have become an almost daily occurrence as the war enters its 19th month and Kyiv’s forces pursue a counteroffensive. Notably, these drones have reached deeper into Russian territory.
Kyiv officials typically neither confirm nor deny responsibility for attacks on Russian soil. This apparent Ukrainian strategy appears to aim at unsettling Russia and exerting pressure on Russian President Vladimir Putin.
It remains uncertain whether these drones are launched from Ukraine or from within Russia itself.
Destruction of Il-76 Planes Examined
In parallel, satellite images scrutinized by AP indicate that suspected Ukrainian drone attacks late on Tuesday led to the destruction of at least two Ilyushin Il-76 military transport planes at a Russian airbase.
These images, captured on Thursday, depict Princess Olga Pskov International Airport, a dual military-civilian airport located approximately 700 kilometers (400 miles) north of the Ukrainian border, in proximity to Estonia and Latvia.
The four-engine Il-76 serves as a cornerstone of the Russian military’s airlift capabilities, capable of landing and taking off in challenging conditions. The Russian military is estimated to possess over 100 of these aircraft.
The AP analysis, conducted on Friday, revealed what appeared to be the charred remnants of two Il-76s on separate parking pads at the airbase’s apron. One included the plane’s tail, while the other showed signs of fire damage and fragments from another aircraft.
Furthermore, eleven other were moved from their parking spots to airport taxiways, possibly to enhance security against future attacks. One Il-76 was on the runway, while another remained parked on its original pad, with unclear reasons.
Local reports have indicated that Ukrainian drone attacks on the airbase resulted in damage to four Il-76s.
Uncertainty Surrounds Mysterious Drone Attacks on Russian Airbase
The satellite image was captured at 1303 GMT on Thursday. Videos circulated on social media on Thursday night depicted anti-aircraft fire near the airbase. However, it remains uncertain whether this signified another attack.
Cloud cover initially obstructed satellites from obtaining an unobstructed view of the Pskov airbase targeted on Tuesday night.
On Thursday, Ukrainian President Volodymyr Zelenskyy revealed that his country had developed a weapon capable of striking a target 700 kilometers (400 miles) away, an apparent reference to the airbase attack. He described Ukraine’s Ministry of Strategic Industries as the producer of the weapon but did not provide further details.
Throughout the ongoing conflict, Kremlin forces have employed numerous salvos of Iranian-made exploding drones to target Ukraine. | aerospace |

For one thing, the inexpensive electric helicopters are very difficult to fly in the wind. Yes you can buy a pretty good one for around $200. The CX is the easiest to learn to fly as compared to the CP and the equivalent, but all helicopters, fuel powered or electric, are difficult to teach yourself to fly. Chances are good you will break many parts in the learning process and most likely give up after spending too many hours fixing, practicing and/or tons of money in the learning process. Hate to discourage you, but this is the reality of RC helicopters.
People seem to think because the helicopters are electric and cheap; it will make it easier to learn how to fly. I've trained something on the order of 300 people to hover and fly helicopters over the years and I know for a fact that is the safest, easiest and cheapest way to learn.
Fuel powered helicopters are difficult to learn to hover and fly, small electric helicopters are even harder and the tiny ones are worse. You will need a large open area to practice hovering and even then, chances are you will break things. This is something you will unfortunately find out after you spent quite a bit of money on your helicopters and replacement parts.
If you haven't already, tried installing a new and/or different type of glow plug. It is possibly there is a hole in your fuel line inside of your tank where the fuel line is attached to the metal pick up. That would cause it to stall when the tank is half empty. The engine might be overheating due to the lean mixture caused by the possible split fuel line. There are so many electric helicopters out there and it depends on what you consider is too expensive.
Save your $100 because buying those helicopters would be a total waste of money. As the saying goes, you only get what you pay for. The same goes for the cheapest electric ARF airplanes. You will need a proper trainer airplane, and any RC warplane is well beyond any beginner's abilities.
Learning to fly RC airplanes is something that is possible to learn on your own, but definitely not recommended. If you ever get a chance to find a club or an experienced flier who will let you fly a proper trainer, then you will see what I'm talking about. I believe collective helicopters are easier to fly than fixed pitched helicopters. You are correct about the CP. The small electric helicopters are for the most part are harder to fly than fuel powered helicopters.
There are several different people who are considered to be the inventor of the helicopter. I could write a book explaining it in detail, but I'll cover a couple of the primary contributors to the development of rotary wing aircraft. The ancient Chinese invented a toy for children that you can still see today. It consists of a propeller and a shaft through the middle of it. If you spin it quickly in your hands or with some other force such as a rubber band you could make it lift up and hover briefly before coming back to the ground.
The first recorded depiction of a possible manned helicopter is a diagram drawn by Leonardo da Vinci in the 1400s. The knowledge of physics necessary to successfully build a working model did not yet exist, but he understood the concept of an "air screw" that if turned fast enough would be able to drive the machine and a pilot into the air.
Over the course of the next few centuries many other people toyed with the idea of a helicopter, but again the amount of power necessary to drive such a machine into the air was not possible to generate. The invention of the internal combustion engine made the power requirement a reality. The next hurdle that needed to be overcome was the concept of torque - the phenomenon that causes the body of the helicopter to spin in the opposite direction of the main rotor.
Paul Cornu invented a working piloted helicopter in 1907, but it was not a successful design. It only generated enough lift for about 7 seconds. Another Frenchman, Etienne Oehmichen built and flew a working helicopter for about 1 kilometer in 1924.
As early as 1910, Russian born Igor Sikorsky began working on development of a manned helicopter. By 1940, his working design had become the model for all modern helicopters. It consisted of a main rotor and a tail rotor that is used to counteract the torque generated by the main rotor. This design is still used in a vast majority of helicopters today, which is why Sikorsky is considered the father of the modern helicopter.
There are many other men who contributed to the development of rotary wing aviation - too many to list here, but a thorough search of the library and/or the internet can give you tons of insight into the development and design of all different types of helicopters.

The ongoing project will bring six crew members to the Mars Desert Research Station outside of Hanksville, Utah (population 214,) where the stark topographical conditions are comparable to those of the red planet. There, volunteers spend two weeks carrying out the equivalent of an elaborate astronaut cosplay, roaming the desert in space suits and oxygen tanks as they carry out individual research projects in restricted conditions. It may sounds like a really elaborate sci-fi version of Dungeons & Dragons, but in truth these missions are helping NASA do some important R&D for an eventual mission to Mars.
“I’m very proud,” he said in a recent statement regarding his selection. “Now in Mexico we need to support each other to get ahead, and it fills me with pride to be able to carry the flag of Mexico on such an important mission, and make the first mission to Mars a real possibility.”
The UNAM physics student made headlines last year when he became NASA’s youngest student-researcher, a distinction he earned after publishing a paper in the Journal of Physics that outlined a new method for detecting radiation levels in outer space. But even if the thermoluminescent properties of stronium 90 aren’t your thing, most anyone can get pumped about a Mars landing – even if they’re just playing pretend. Either way, we’re one step closer to seeing Mexico’s glorious tricolor waving in the methane breeze of our neighboring planet. | aerospace |

TanDEM-X is a unique mission to derive Digital Elevation Models (DEMs) with two SAR satellites in orbit since 2007 and 2010. The acquisition of the first global DEM was performed until 2014. After a first science phase was performed between 2014 and 2017, an update of the global DEM, called “Change DEM”, was acquired between 2017 and 2020. Currently, a second science phase is carried out concentrating on permafrost areas, forests and the major cities of the world. DLR is also pushing for the time after TanDEM-X with Tandem-L, a proposal for a sophisticated satellite-duo operating in L-band, serving a variety of applications. The paper describes the acquisition concepts for both missions which are of crucial importance for delivering high-quality DEM data to scientific and commercial users. | aerospace |

the activity of flying a glider
The hobby, sport or act of flying a glider.
Gliding is a recreational activity and competitive air sport in which pilots fly unpowered aircraft known as gliders or sailplanes using naturally occurring currents of rising air in the atmosphere to remain airborne. The word soaring is also used for the sport. Gliding as a sport began in the 1920s. Initially the objective was to increase the duration of flights but soon pilots attempted cross-country flights away from the place of launch. Improvements in aerodynamics and in the understanding of weather phenomena have allowed greater distances at higher average speeds. Long distances are now flown using any of the main sources of rising air: ridge lift, thermals and lee waves. When conditions are favorable, experienced pilots can now fly hundreds of kilometres before returning to their home airfields; occasionally flights of more than 1,000 kilometres are achieved. Some competitive pilots fly in races around pre-defined courses. These gliding competitions test pilots' abilities to make best use of local weather conditions as well as their flying skills. Local and national competitions are organized in many countries, and there are biennial World Gliding Championships. Techniques to maximize a glider's speed around the day's task in a competition have been developed, including the optimum speed to fly, navigation using GPS and the carrying of water ballast. If the weather deteriorates pilots are sometimes unable to complete a cross-country flight. Consequently they may need to land elsewhere, perhaps in a field, but motorglider pilots can avoid this by starting an engine.

Stratech Systems (http://www.stratechsystems.com/) has announced that the Civil Aviation Authority of Singapore (CAAS) will deploy its iFerret Runway Surveillance System, in the first commercial implementation of the award-winning solution.
|Foreign object damage poses a perennial hazard to aircraft operations and passenger safety.|
The iFerret system, which detects, identifies, tracks and displays foreign objects in real-time, will be deployed on Runways 1 and 2 at Singapore's Changi Airport. As part of the deal, which is valued at over S$12 million, Stratech will customise the system to Changi Airport's requirements and perform system maintenance and upgrades.
Foreign object damage (FOD) poses a perennial hazard to aircraft operations and passenger safety. It is estimated that aircraft repairs, flight delays and airport maintenance stemming from FOD cost the global aerospace industry about US$4 billion a year.
"The prevention of FOD incidents has always been a priority at Changi Airport. For example, the frequency of our runway inspections already exceeds guidelines set by the International Civil Aviation Organisation," said Mr Lim Kim Choon, Director-General and Chief Executive Officer of CAAS. "iFerret will enable us to automate these inspections and set even higher standards in operational efficiency and passenger safety," he added.
An all-weather automated system, it is the first of its kind to be based on intelligent-Vision, a form of artificial intelligence that enables machines to "see" in real-time, providing the means for critical-decision support. The system was awarded the Research and Development prize at the Asia Pacific Information and Communications Technology Awards in Macau in 2006.
iFerret can be scaled for airport runways and taxiways of any length, and can also be deployed on airport aprons, airport hangars and even aircraft carriers. CAAS awarded the contract to Stratech following a 15-month pilot trial conducted at Changi Airport.
Dr David Chew, Executive Chairman of Stratech, said, "iFerret represents cutting edge runway surveillance technology, and we hope that it will pave the way for improved safety standards at airports worldwide."
Commenting on the Changi Airport deployment, he said, "The deployment of iFerret at one of the world's best airports is testament to its capabilities, and is in line with our 'powered by Stratech' strategy to commercialise the company’s intellectual property."
iFerret has also been recommended for evaluation at Chicago's O'Hare International Airport, by the Centre of Excellence in Airport Technology at the University of Illinois, a performing partner for the Federal Aviation Administration R&D Centre in the United States.
ntelligent Airfield/Runway Surveillance and FOD (Foreign Object & Debris) Detection System
Incidents arising from Foreign Objects & Debris (FOD) on runways cost the aviation industry US$4 billion in aircraft repairs and maintenance annually. Flight delays and accident claims add to the cost. FOD includes a wide range of materials, such as a part fallen off from an aircraft, a detached runway light fitting, building materials, rocks and even wildlife. The Air France Concorde crash in July 2000, which claimed 113 lives, reinforces the need for real-time, automated FOD detection.
Currently, airports conduct daily manual runway sweeps to remove FOD. This tedious and error-prone process can be automated through iFerret™ - the world’s first intelligent vision-based FOD detection system. iFerret™ is designed to detect and classify foreign objects, as well as pinpoint their location. This revolutionary system features self-calibrating cameras, automated scene analysis and configurable scan resolution for different object sizes. Providing continuous runway inspection in-between flights, it facilitates rapid recovery response through accurate assessment and real-time alert for FOD, bird strike condition, and even battle damage surveillance.
iFerret™ has won the R&D prize at the Asia Pacific ICT Awards (APICTA) 2006 . It was also awarded The Enterprise Challenge (TEC) Initiative by the Prime Minister’s Office of Singapore.

What was the name of the first mission that was sent to take pictures of Mars in a fly by?
While those first several missions didn’t reach their target, NASA’s Mariner 4 finally did. The spacecraft launched on Nov. 28, 1964, and was the first to fly by Mars on July 14, 1965. It sent 21 photos of the Red Planet back to Earth.
What was the first picture taken on Mars?
On August 20, 1975, NASA’s Viking 1 Orbiter and Lander launched from Cape Canaveral, Florida. Eleven months and half a billion miles later the Viking 1 lander touched down on Mars and sent home the first picture ever taken on the Martian surface.
When were the first close up pictures of Mars taken?
Pickering. Mariner 4 was launched on November 28, 1964 and journeyed for 228 days to the Red Planet, providing the first close-range images of Mars.
What was the name of the mission that first landed a spacecraft on Mars?
The Viking landers were the first spacecraft to land on Mars in the 1970s. Viking 1 and Viking 2 each had both an orbiter and a lander. On July 20, 1976 the Viking 1 Lander separated from the Orbiter and touched down on the surface of Mars.
When was the first photo taken?
Centuries of advances in chemistry and optics, including the invention of the camera obscura, set the stage for the world’s first photograph. In 1826, French scientist Joseph Nicéphore Niépce, took that photograph, titled View from the Window at Le Gras, at his family’s country home.
When was the first photo of Earth?
October 24, 1946
But 75 years ago — before Scott Kelly was given a Nikon D4, and before the famous “Blue Marble” full view of Earth — there was this. The very first photograph of Earth from space. It was taken on October 24, 1946.
What landed on Mars and took pictures?
Nasa’s Perseverance rover landed on Mars at 20:55 GMT on 18 February after almost seven months travelling from Earth. Since then, it has sent back some amazing images from around its landing site, Jezero Crater, a 49km (30-mile) wide impact depression just north of the Red Planet’s equator.
What is the name of the famous photograph from this rover?
The picture, of course, is the famous “Face on Mars” picture, taken by the Viking 1 spacecraft as it made its way to the Red Planet.
What was the name of the spacecraft that first landed on the moon?
The first moon landing occurred on July 20, 1969, on the Apollo 11 mission. The crew of Apollo 11 was Neil Armstrong, Michael Collins and Buzz Aldrin. Armstong and Aldrin walked on the lunar surface while Collins remained in orbit around the moon.
What was the name of the first space station?
On April 19, 1971, the Soviet Union placed into orbit Salyut, the world’s first space station. Designed for a 6-month on orbit operational lifetime, Salyut hosted the crew of Georgi T.
Who first landed on moon?
Commander Neil Armstrong
Apollo 11 (July 16–24, 1969) was the spaceflight that first landed humans on the Moon. Commander Neil Armstrong and lunar module pilot Buzz Aldrin formed the American crew that landed the Apollo Lunar Module Eagle on July 20, 1969, at 20:17 UTC.
Who took the first ever photo?
Joseph Nicéphore Niépce
The world’s first photograph—or at least the oldest surviving photo—was taken by Joseph Nicéphore Niépce in 1826 or 1827. Captured using a technique known as heliography, the shot was taken from an upstairs window at Niépce’s estate in Burgundy.
Who named Planet Earth?
All of the planets, except for Earth, were named after Greek and Roman gods and godesses. The name Earth is an English/German name which simply means the ground. It comes from the Old English words ‘eor(th)e’ and ‘ertha’. In German it is ‘erde’.
Who was the first photograph?
This photo, simply titled, “View from the Window at Le Gras,” is said to be the world’s earliest surviving photograph. And it was almost lost forever. It was taken by Nicéphore Niépce in a commune in France called Saint-Loup-de-Varennes somewhere between 1826 and 1827. | aerospace |

The engineering problem referred in the title of this article is important not for the definite application only. This complex problem is also a good example of a great variation of the physical conditions of thermal radiation for combustion products containing solid or liquid micron-size alumina particles.
In the combustion chamber, the optical thickness of the two-phase combustion products is so high that the major processes take place near the chamber walls near the solid propellant surface. As a rule, the appropriate models are usually 1D, but one should take into account the coupled radiation-convection effects in the thermal boundary layers. In the supersonic nozzle, the density, temperature, and optical thickness of combustion products decrease sharply with the expansion degree (along the nozzle axis). As a result, a contribution of the local thermal radiation to the heat flux to the nozzle wall is not significant. But the net radiative flux at the wall is not negligible. It can be determined on the basis of the 2D solution for the spectral radiative transfer problem, and the radiation scattering by alumina particles appears to be very important. Contrary, the radiation from the exhaust jet as a whole is weakly sensitive to the scattering effects (excluding some near-field problems), but it is important to know the real temperature and absorption-emission properties of polydisperse alumina particles. The dynamic and thermal nonequilibrium of particles suspended in the gas flow and the real temperature behavior of the infrared absorption index of alumina determine the thermal radiation of the rocket plume. The above-mentioned special features of the radiation heat transfer in solid-propellant rocket engine are considered in several subsequent articles specified under the title of the present article.
For the convenience of a reader, the major references on the problem under consideration are presented below in chronological order, starting from the early paper by Nelson published in 1984. Some more detailed (and sometimes earlier) references and their discussion are included in the particular articles on thermal radiation in the combustion chamber, the supersonic rocket nozzle, and in the exhaust jet.

Europe aviation agency urges extending black box life.
Europe's aviation safety watchdog today, called for the life of black box flight recorders to last 3 times as long, as the hunt for the missing Malaysia Airlines plane yields no results.
In a statement, the European Aviation Safety Agency urged "the extension of the transmission time of underwater locating devices fitted on flight recorders from 30 days to 90 days.
The black box refers to the cockpit voice recorder and flight data recorder on planes, which are crucial in determining what triggered a plane crash but can be very difficult to locate, as has been the case with the Malaysia Airlines flight that disappeared at sea on March 8th carrying 239 people. | aerospace |

SU-22 Kill over the Persian Gulf info
In late January 1981 two F-14's from Khatami Air Force Base were on combat
patrol over the southwest region of the Persian Gulf. At around noon, Iranian ground
radar picked up a target approximately 100 to 200 feet above sea level in the southern region of the Gulf, moving at a high rate of speed toward Bushehr. The ground radar operator directed the F-14's to the incoming object.
At this time the lead F-14 radar picked up the same aircraft and secured a radar lock on the target. After confirming the target was definitely hostile, and flying at a very low altitude and only a little over 30 miles away, the lead F-14 fired an AIM-54A Phoenix missile. The Phoenix hit the Iraqi SU-22 in the middle of the fuselage, cutting it in half.
Later the Radar Interception Officer in the lead F-14 reported seeing a fireball followed
by an immediate splash down in the ocean, confirming the very low altitude of the Iraqi SU-22. The RIO also observed a second SU-22 at this time, which was not picked up by radar earlier.
However the second SU-22 managed to evade the scene.

AIM-54 Phoenix Missile
The AIM-54 Phoenix Long-range air-to-air missile, carried in clusters of up to six missiles on the F-14 Tomcat. The Phoenix missile is the Navy's only long-range air-to-air missile. It is an airborne weapons control system with multiple-target handling capabilities, used to kill multiple air targets with conventional warheads. The weapon system consists of an AIM-54 guided missile, interface system, and a launch aircraft with an AN/AWG-9 weapon control system. The AIM-54 is a radar-guided, air-to-air, long-range missile consisting of a guidance, armament, propulsion, and control section, interconnecting cables, wings and fins. The total weapon system has the capability to launch as many as six AIM-54 missiles simultaneously from the F-14 aircraft against an equal number of targets in all weather and heavy jamming environments.Specifications

In my opinion air warfare is so dull and sterile now. Look at that for combat. Killed in a flash by an enemy he probably never knew was there. Oh for the glory days of air combat in the second world war.

F-14 is an interceptor.In With in Visual range combat even the old Su-22 would of cut it to pieces.

The whole audio transcripts of the incident are available on the internet and you are correct LT, they were within visual range. I'll see if I can hunt up the link, its got a bit of profanity but not too bad.

Actually, I'm not sure the audio is available from the Aug. 1981 incident (F-14 vs. Su-22) -- the one everyone keeps linking is the 1989 incident (F-14 vs. MiG-23). Unless you've got something new...?

I think you're right LT but I did find this...
Hence the kills took place at a distance of less than 9 miles, i.e. visual range. | aerospace |

Dozens of other industries are lined up to follow Hollywood’s lead. Until now, the Federal Aviation Administration, which is part of the Transportation Department, had banned commercial drone operations with the exception of a lone oil company in Alaska.
The FAA permits come with limitations, including that the unmanned aircraft be used only in a restricted area, that they be flown under 400 feet in altitude and that flights last no more than 30 minutes at a time. Nighttime flights are prohibited, and reality television shows or other unscripted events won’t qualify for the permits.
"Today’s announcement is a significant milestone in broadening commercial (drone) use while ensuring we maintain our world-class safety record in all forms of flight," Foxx said. "These companies are blazing a trail that others are already following, offering the promise of new advances in agriculture and utility safety and maintenance."
Tony Carmean, a partner in Aerial MOB of San Diego, predicted drones will fundamentally change moviemaking, providing directors with the ability to get shots they could never get before and making films more dynamic. Small drones with video cameras will be able to fly through a building and in and out of windows, for example, he said. They are also far less expensive than hiring a manned helicopter, he said. | aerospace |

The ginger Mike Collins!!
Col., USAF, was an American aeronautical engineer, United States Air Force pilot, test pilot, and NASA astronaut, who was the Command Module Pilot for the Apollo 14 mission. The mission lasted from January 31 to February 9, 1971 and was the third mission to land astronauts (Alan Shepard and Edgar Mitchell) on the Moon. While Shepard and Mitchell spent two days on the lunar surface, Roosa conducted experiments from orbit in the Command Module Kitty Hawk. He was one of 24 men to travel to the Moon, which he orbited 34 times
1933 - On Aug. 17, The group of Soviet engineers from GIRD (Group for Investigation of Reactive Motion) successfully fired the first Soviet rocket burning liquid oxygen. The GIRD-09 experimental vehicle, (Rocket Projectile No. 9) flew for 18 seconds and reached around 400 meters in altitude before crashing back to Earth. Rocket Projectile No. 9, The development of Vehicle 09 was centered at GIRD's Design Brigade No. 2 led by Mikhail Klavdievich Tikhonravov (pictured) under the leadership of Sergei Korolev. Really a hybrid rocket beacuse the propelland was a Jelly like version of petrol (gasoline) known as "solid benzene"

Tim Peake: will take an unpaid leave of absence from ESA for two years from 1 October 2019. for personal and career development.
While continuing to support ESA he will work more closely with the United Kingdom Space Agency (UKSA) education and outreach also his (STEM) ambassador for the UK, Prince’s Trust and Scout ambassador, but NOTT In 2016, ESA Director General Jan Wörner stated his intention that all astronauts in the class of 2009 will fly twice by 2024.
On 25 July, an asteroid the size of a football field flew by Earth, coming within 65 000 km of our planet’s surface during its closest approach – about one fifth of the distance to the Moon. The 100 m-wide asteroid dubbed '2019 OK' was detected just days before it passed Earth, although archival records from sky surveys show it had previously been observed but wasn't recognized as a near-Earth asteroid. Would have been a once in a 10,000 year event with the potential to be as powerful as the 50 mt Tzar Bomba. An estimated 30,000 of these bugger are yet to be found.
Franklin in trouble!!!
We might see the Franklin rover launch in 2022 now due to pesky parachute problems
The Nasa Russell Rover (or Mars 2020) I assume they will call it the Russell rover after esteemed astronomer Henry Norris Russell? Will still be on time.
The ESA Franklin rover parachute is The largest-ever space parachute! As far as I can tell,
at 115 feet (35 meters) across, weighs almost 200 lbs. (90 kilograms) and is equipped with 3 miles (5 kilometers) of cords. it takes five working days to prepare and fold the parachute into its correct configuration.
Curiosity’s parachute was only 16m across ...half the size!!! And was th biggest space parachute ever.

Chandrayaan-2 has been orbiting the earth on an orbit that takes it to an altitude of 142,975km from the Earth at the farthest point (apogee) and brings its as close as 276km at the nearest point (perigee), but has sucsesfully done an engine burn to take it to Lunar transfer to be caught by moon gravity by August 20th and land september 7th.
The x37b has past 700 days up there doing dod knows what. ...testing American liquid metal nuclear propulsion ??
JWST might be able to do some amazing atmosphere detection of trappist 1 system in it’s first year. All assuming it doesn’t blow up on the launch pad. In a paper published in the astronmical journla titled, The Detectability and Characterization of the TRAPPIST-1 Exoplanet Atmospheres with JWST by Jacob Lustig-Yaeger, Victoria S. Meadow, and Andrew P. Lincowski
Basically using computer models to see what types of terrestrial exoplanet atmospheres can be detected in the smallest ammoun of transits of each planet with JWST. Nice bit of ground work to speed things up, get that lost observation time back.
Blackhole Flare up (via Tuan Do of UCLA on twitter)
Depending on your point of view, this happened either on May 13, 2019 UT or 26,000 years ago. @keck observatory saw the supermassive black hole Sgr A*. The black hole is always variable, but this was the brightest in the infrared by double for 20 years of observation!!! It was probably even brighter before observing that night! Maybe that gas from the object G2 which went through closest approach in 2014 took a while to get to the black hole, may be from changes in the accretion-flow as a result of the star S0-2's closest passage to the black hole in 2018. Could be big!!! Stay tuned on this one!

This makes the best Fibre optical cable you can get, and is seriously useful in furthering our technical capability, but you can best make it better in space by far, because of Zero G, and Made in Space actually "3d print" or Pull ZBLAN on the iss. Making it probably the first true industrial process in space, so along with it’s other microwave sized device the first commercially available 3D printer in space, the AMF, they are the bollox in space industrial engineering.
"For Made In Space, projects like RAMA that exist somewhere near the edges of our product roadmaps help drive all our closer term work in the right direction. For all of us in the US, we are lucky to have an agency like NASA, which has the vision to continue to fund NIAC and other programs that will define the future resiliency of our species"

A NASA NIAC (innovative advanced Concepts) report - RAMA - reconstituting Asteroids into Mexhanical Automata
The objective of this study is for Made In Space (MIS) to establish the concept feasibility of using the age-old technique of analog computers and mechanisms to convert entire asteroids into enormous autonomous mechanical spacecraft
“It has long been understood that harnessing the mass of the asteroids and using it to manufacture equipment outside of Earth’s gravity well would be an enabler of the space frontier”. Wow.
“For now, the cost to mine these asteroids is far more expensive than the cost of extracting equivalent resources from Earth. But that will not always be true. In the next few decades, the convergences of several exponentially accelerating technologies are expected to dramatically reduce costs for space resource mining endeavors. Logically there will be a tipping point when it will become economically feasible to switch to an off-world resource extraction and mining paradigm.”
Made In space made the report to address
Issues with Building Space based Infrastructure
The need for Space based resources: How do you get at all these reources just lying around in space
Launch and propulsion
Data collection and asteroid detection
Remotely mining asteroids without the need for humans
Generative design algorithms
Transportation of asteroid resources – This core-unsolved problem is the focus of the Project RAMA Phase I study. - RAMA architecture, which turns asteroids into self-contained spacecraft capable of moving themselves back to cislunar space
Currently “Space Industry” means using space to produce data, not physical products (i.e. telecommunications, remote sensing, Earth observation)
Made In Space believes that space will become a useful place to produce physical goods. Microgravity (and partial artificial gravity) will be used to precisely control the manufacturing of products made from exotic materials and manufacturing processes that on Earth rely on the costly use of inert gasses will be moved to space
The concept in a nutshell: what would it take to turn asteroids into self-powered spacecraft?
RAMA : The concept is based on a “Seed Craft”; a spacecraft which contains technically sophisticated ISRU, Additive Manufacturing and robotic capabilities. The Seed Craft uses these capabilities to convert the available materials of an asteroids into spacecraft subsystems including propulsion, energy storage and guidance systems.
The asteroid (now a spacecraft in its own right) is able to autonomously carry out a basic mission; such as relocation for easier future rendezvous, or to divert to a more useful location of empty space.
Meanwhile, the Seed Craft which initiated the transformation is free to plot a course to the next asteroid, repeating the RAMA process indefinitely
However, the technology doesn’t exist, but MIS anticipate ten to twenty years from now they will be developed to a technology readiness level high enough for the initial RAMA missions
The BIG IDEA! RAMA makes use of materials found at the asteroid for mass intensive tasks (like providing reaction mass for the propulsion systems), a greater mass can be returned for equivalent mass launched, so the “useless” materials on the asteroid is put to good use in the RAMA concept as structural support and propellant reaction mass
Taken to the extreme, the RAMA architecture enables a train of mechanically driven, asteroid spacecraft, “mine carts,” stretching from the depths of the asteroid belt to the Earth-Moon system. “free rides” to interplanetary space and back. Over time, you convert these into sophisticated vehicles fit for human habitation; or fit them with sensors as research platforms to map other asteroids.
Ultimately RAMA will create a system that will give humanity access to safer, faster and cheaper options for accessing the wealth of resources in our solar system.
Finding Asteroids -
Very Little information can be gathered about asteroids, from telescopic observations alone
Large asteroids have enough gravity that even if they are loosely packed they hold together when spinning, smaller one must be solid if they are spinning and still holding together, different types require different techniques, so it’s important to categorize them
Next to diameter, the most important property of an asteroid is arguably its mass, which is impossible to measure from the ground. Until the asteroid is visited by a spacecraft, details like its mass can only be guessed at
Common Types (but a spectrum in reality)
Dark C (carbonaceous) asteroids, which make up most asteroids and are in the outer belt. less common near Earth orbit. lower density, and a higher prevalence of organic compounds, water-ice and other volatiles.
Bright S (silicaceous) asteroids and are in the inner belt, closer to Mars.The most common near Earth object type, stony/metallic composition with very little water-ice or volatiles.
Bright M (metallic) asteroids. Psyche 16 being the mother of them all!
RAMA it self
The Case for a “Mechanical” Spacecraft - think The Antikythera - if Archimedes can do it 2000 years ago ...why not
Propulsion systems to move 100-meter asteroids are too large to launch, but can be built in-situ as mechanical mass drivers;
flywheels for attitude control are too heavy to launch, but could be constructed within an asteroid to control its spin rate and store energy.
It is also possible to create mechanical computation devices for spacecraft that could perform basic avionics-style routines. For missions that require independence from Earth, with no supply of Earth made electronics, the creation of basic mechanical computers may serve as an alternative.
Clearly, propulsion is a capability that is better provided from asteroid resources than communications or computing power, bringing propulsion from Earth would more than double the mass of the Seed craft for even a modestly sized 5m asteroid, and would be completely impossible for an asteroid in the target 50-100m range for RAMA. Up to the designer of future RAMA concepts to perform the Bring vs. Build tradeoff for a given asteroid
Example RAMA Process (RAMA -1)
2038, the RAMA Seed Craft will use electric propulsion and gravity assists to fly towards and intercept Near Earth Asteroid 2009 UY19, 36-163 meters wide, and will be within 15 Lunar Distances of Earth in 2039 and approximately every 33 years thereafter.
The RAMA Seed Craft analyzes the asteroid, and begins effectively organizing available in-situ resources.
The asteroid is broken down and materials are stockpiled as manufacturing feedstocks, as well as viable “waste” mass for propellant. (techniques pioneered by the NASA KSC Swampworks team and industry asteroid mining initiatives)
Mechanical energy storage systems are also fabricated on the asteroid, and charged with power from the Seed Craft.
Seed Craft assembles a unique array of mechanical linkages for the asteroid from ISRU derived components. These will allow for timing and control of the asteroids systems after the Seed Craft has departed for the next target.
When the Seed Crafts departs, it triggers the asteroid’s carefully pre-programmed sequence of events, which sets the asteroid on its own path to return to cislunar space without the Seed Craft., Putting it on a new course to the Earth-Moon L5 point where asteroid mining activity is underway, and waiting for the RAMA-1 resources. The seedcraft goes on to build RAMA-2
Easily intercepted using conventional techniques (remember ARM)
A really cool output From the study is Rockfinder
A tool they have developed to find the asteroids in the first place, Asteroids that are suitable for the RAMA system. :
The goal is for Rock Finder to be integrated into a single code library or browser application with a cleaner front end that would allow the process to be duplicated by anyone interested in utilization of asteroid resources. Using the software keeping an eye on discoveries potentially as disruptive to a future asteroid mining industry as a gold or oil boom in the 1800’s, could seriously assist any one who makes their fortunes on the asteroid mining sector,
Flying through space like a giant jelly fish!!!
Using giant metallic slings to fly RAMA spacecraft looks similar to a jellyfish swimming through the ocean currents
The Seed Craft uses its own propulsion system to provide a series of forward “kicks” to the asteroid. These kicks impart no significant ΔV, but are properly timed to match the fundamental frequency of the 16 extended slings protruding from the asteroid.
The slings begin to oscillate back and forth, and after 3 days of continuous kicks, the slings are rocking back and forth with a high enough amplitude to be bend all the way back to the asteroid’s surface. The slenderness ratio of the slings (250:1) is large enough to remain fully elastic when bent this far, allowing it to continue to oscillate like a pendulum with only thermal losses.
The Seed Craft, its decades long task complete, disengages from the asteroid and departs for its next target.
The slings, once set in motion, oscillate at a period of 2.1 seconds, and at the peak of their swing, the tips are travelling at 312 m/s, achieving the theoretical maximum velocity of the material. At the extreme of each swing, the tip of the sling passes close to the exit ports near the asteroid’s equator, where extremely strong rare Earth magnets on the tip of each sling adhere to a single 10 kg shot. The strength of the permanent magnet on the tip and the remnant magnetism if the shot is calibrated such that the adhesion strength is exceeded exactly at the full extension of the swing, where the centrifugal force is maximized, hurling the shot astern of the asteroid at 312 m/s, and imparting a small but non-trivial 13 microns/sec ΔV onto the asteroid.
At full “throttle”, with all slings operating, the asteroid accelerates at a constant 11 micro-gs.
Asteroid deflection and planetary protection!
Calculations by Metzger et al. suggest that some NEOs would be too massive to alter their course using conventional chemical propulsion alone While this study has not focused on planetary protection applications, there is room for an interesting future study on using RAMA to reduce the mass of a potentially hazardous super massive NEOs, until it they fall within the bounds of current deflection technologies
Human Exploration Missions
Rather than using this RAMA mission for delivery of an asteroid to a space resource processing facility at L5, it could instead be sent to L5 to be outfitted with large solar arrays, communication infrastructure and terraformed internally with a pressurized atmosphere to become a space habitat for human deep space exploration. A new class of human exploration missions could ensue in which the astronauts spend many years within the RAMA space habitat, while it journeys throughout the solar system.
Some NASA concept studies include:
As discussed last week
Island One, a Bernal sphere habitat for about 10,000–20,000 people.
Stanford torus: an alternative to Island One.
O'Neill cylinder: "Island Three", an even larger design (3.2 km radius and 32 km long).
Lewis One; A cylinder of radius 250 m with a non rotating radiation shielding. The shielding protects the micro-gravity industrial space, too. The rotating part is 450m long and has several inner cylinders. Some of them are used for agriculture.
Kalpana One, A short cylinder with 250 m radius and 325 m length. The radiation shielding is 10 t/m2 and rotates. It has several inner cylinders for agriculture and recreaction It is sized for 3,000 residents.
A bola: a spacecraft or habitat connected by a cable to a counterweight or other habitat. This design has been proposed as a Mars ship, initial construction shack for a space habitat, and Orbital hotel. It has a comfortably long and slow rotational radius for a relatively small station mass. Also, if some of the equipment can form the counter-weight, the equipment dedicated to artificial gravity is just a cable, and thus has a much smaller mass-fraction than in other concepts. For a long-term habitation, however, radiation shielding must rotate with the habitat, and is extremely heavy, thus requiring a much stronger and heavier cable
Beaded habitats: This speculative design was also considered by the NASA studies. Small habitats would be mass-produced to standards that allow the habitats to interconnect. A single habitat can operate alone as a bola. However, further habitats can be attached, to grow into a "dumbbell" then a "bow-tie", then a ring, then a cylinder of "beads", and finally a framed array of cylinders. Each stage of growth shares more radiation shielding and capital equipment, increasing redundancy and safety while reducing the cost per person. This concept was originally proposed by a professional architect because it can grow much like Earth-bound cities, with incremental individual investments, unlike those that require large start-up investments. The main disadvantage is that the smaller versions use a large structure to support the radiation shielding, which rotates with them. In large sizes, the shielding becomes economical, because it grows roughly as the square of the colony radius. The number of people, their habitats, and the radiators to cool them grow roughly as the cube of the colony radius
Bubbleworld: Dandridge M. Cole in 1964. The concept calls for drilling a tunnel through the longest axis of a large asteroid of iron or nickel-iron composition and filling it with a volotile substance, possibly water. A very large solar reflector would be constructed nearby, focusing solar heat onto the asteroid, first to weld and seal the tunnel ends, then more diffusely to slowly heat the entire outer surface. As the metal softens, the water inside expands and inflates the mass, while rotational forces help shape it into a cylindrical form. Once expanded and allowed to cool, it can be spun to produce artificial gravity by centrifugation, and the interior filled with soil, air and water. By creating a slight bulge in the middle of the cylinder, a ring-shaped lake can be made to form. Reflectors would allow sunlight to enter and to be directed where needed. This method would require a significant human and industrial presence in space to be at all feasible. The concept was popularized by science fiction author Larry Niven in his Known Space stories, describing such worlds as the primary habitats of the Belters, a civilization who had colonized the asteroid belt.
Asteroid terrarium: a similar idea to the bubble world, the asteroid terrarium, appears in the novel 2312, authored by hard science fiction writer Kim Stanley Robinson.
Bishop Ring: The MEGA behemo-gargantuanly massive design using carbon nanotubes, a Bishop Ring is a torus 1000 km in radius, 500 km in width, and with atmosphere retention walls 200 km in height. The habitat would be large enough that it could be "roofless", open to outer space on the inner rim.
McKendree cylinder: another concept that would use carbon nanotubes, a McKendree cylinder is paired cylinders in the same vein as the O'neill Cylinder, but each 460 km in radius and 4600 km long | aerospace |

The pilot suffered a medical emergency, leading to this unfortunate incident, as confirmed by officials.
LATAM Airlines Group issued a statement to USA TODAY, revealing that the flight was en route to Santiago, Chile, from Miami, Florida, when one of the three members of the command crew required urgent medical attention.
Upon facing this medical crisis, the airline’s crew made an emergency landing at Tocumen International Airport in Panama City, Panama. Despite the prompt response from first responders in an attempt to aid the pilot, their efforts were in vain, and the pilot passed away, as announced by the airline.
The airlines expressed deep sorrow over the incident and took the opportunity to convey heartfelt condolences to the pilot’s family. The airline also praised the pilot’s 25 years of service to LATAM, commending their dedication, professionalism, and enthusiasm, without disclosing the pilot’s identity in the provided statement.
A passenger named Brett Ploss, who was on the flight, recounted observing the flight attendants in a state of agitation, running back and forth along the aisles. While the passengers initially remained unaware that it was the pilot who was in distress, the concerned demeanor of the flight attendants did not go unnoticed.
Ultimately, Flight LA505 safely reached its destination in Chile at 4:00 a.m. on Wednesday, marking the end of this unexpected and sorrowful journey. | aerospace |

Jacksonville Municipal Airport Number One opened in 1927, with a dedication that included Charles Lindbergh. In 1931, Eastern Air Transit (eventually Eastern Airlines) became the first major commercial airline to provide regular service to Jacksonville.
This illustration is a 1944 Army diagram of Imeson, which was known as Jacksonville Army Air Field at the time. Soon after it would be commissioned as the Naval Auxiliary Air Station Jacksonville #1 with the primary tenant being Operational Training Units for PB4Y-1 Liberator patrol Bombers. After the end of WWII, the airport was returned to the city and renamed Imeson Field, after Thomas Cole Imeson. Imeson, who passed in 1948, was a long time city councilman whose visionary work led to the opening on the airport back in the 1920’s.
This image of the art deco terminal building was taken in the 1940s. During this era, the longest of five runways had a length of 7,000 feet, plus airline service provided by Eastern, Orlando and National Airlines.
Before airlines like Jetblue, Spirit and Southwest hit the scene, there was National Airlines. While Atlanta had Delta, Houston Continental and Detroit Northwest Airlines, Jacksonville had National. Founded in 1934, National's headquarters were based at Imeson Field, until the company relocated its offices to Miami in the late 1950s. National became the first airline to introduce domestic jet service in the United States, with a flight between Miami and New York in 1958. National merged with Pan Am in 1980.
This aerial image of Imeson was taken April 3, 1966, two years before the airport closed for good. By the 1960s, the community realized that with limited expansion space, and larger jet aircraft coming on line, it was time to consider replacing Imeson. In 1965, taxpayers approved a $9 million dollar bond to help fund construction for a new airport a few miles to the Northeast. Upon completion of the new Jacksonville International Airport, Imeson Field was abandoned.
The new Jacksonville International Airport in 1972.

‘Alien’ sand dunes found on Mars
To look at it you’d think the landscape had been carved by aliens.
But these perfectly sculpted sand dunes, resembling crabs’ claws, were sculpted by the martian winds.
The images were photographed by a powerful camera onboard the Mars Reconnaissance Orbiter. They come from within the Hellspontus region of the planet, where powerful winds blow from west to east.
The MRO probe is equipped with the most powerful camera ever sent into space. It also took detailed pictures of Phobos, the larger of Mars’ two moons. Less than 14 miles wide, the asteroid is covered with craters and mysterious grooves.
Chief Nasa investigator Professor Alfred McEwen, of the University of Arizona, said: “Phobos is of great interest because it may be rich in water ice and carbon-rich materials.â€

First invented in World War I, and in widespread use by the 1930s, flaps allow an aircraft to increase the lift generated by its wings by increasing either the camber (curvature) or total wing area (and sometimes both.). This increase in lift reduces the stall speed and allows the aircraft to fly safely at lower speeds than usual. This allows shorter take-off and landing distances, as well as slower (and safer) speeds, during these procedures. 100 things that make safer skies: 31-40
Lightning is a serious danger. Being out-of-doors is the most dangerous place to be when thunderstorms are in the area. It is important to monitor changing weather conditions, and understanding the risks associated with lightning. If you can hear thunder—even a distant rumble, you are already at risk.
To continue ...........................
Dangerous goods control
The danger in taking flammable, volatile cargo on aircraft has been illustrated too many times. South African Airways Flight 295 was lost in the Indian Ocean in November 1987 after an in-flight fire in the cargo hold. The holds of most airliners are now equipped with automated halon fire-extinguishing systems to combat any cargo or baggage fire. In May 1996, ValuJet Airlines Flight 592 crashed into the Florida Everglades a few minutes after take off, when a fire broke out in the forward cargo hold. All 110 aboard were killed. These tragedies also refocused attention on screening to prevent dangerous goods from being carried on aircraft. Dangerous goods control is an ever-changing game.
100 things that make safer skies: 21-30
Safety management systems
Since the first plane crash that killed a passenger of the Wright brothers, aviation safety has followed the model of analysing what went wrong, and trying to do better in future, by making changes to technology or procedures. The death of soldier Thomas Selfridge in the Wright Flyer crash led to army aviators using helmets, for example. But this model of accident-based insight is not available to the nuclear or oil and gas industries, where a single accident can be catastrophic. Instead, these industries take a proactive approach to managing safety, based on a reporting culture and formal processes to ensure safety is managed like any other element of the business.
100 things that make safer skies: 11-20
Safety depends on much more than learning from accidents. It also requires near- misses (or near-hits?) and errors to be remedied. But to do this they have to be reported. This requires an environment in which people feel confident they will not be punished for honest mistakes. The obvious problem is the difference between honest mistakes and negligence—too complex a topic to explore here. Reporting culture in aviation is imperfect, but is always embraced as an ideal. The contrast with other areas such as medicine is marked. More Details 100 things that make safer skies: 1-10

At 13 billion miles from Earth, there's no mechanic shop nearby to get a tune-up. But NASA enginners have successfully fired up a set of "dormant" backup thrusters aboard the Voyager 1 spacecraft -- the farthest and fastest spacecraft -- after 37 years. The only human-made object in interstellar space -- the environment between the stars -- Voyager 1 has been flying for 40 years. It relies on small devices called thrusters to orient itself so it can communicate with Earth.
These thrusters fire in tiny pulses, or "puffs," lasting mere milliseconds, to subtly rotate the spacecraft so that its antenna points at our planet.
Now, the Voyager team is able to use a set of four backup thrusters, dormant since 1980. "With these thrusters that are still functional after 37 years without use, we will be able to extend the life of the Voyager 1 spacecraft by two to three years," said Suzanne Dodd, Project Manager for Voyager at NASA's Jet Propulsion Laboratory, Pasadena, California. | aerospace |

Kinetic Energy Recovery Systems are a great example of a technology that was first developed for Formula 1 cars, but is gaining popularity in the automotive and transportation sectors and can prove to be a significant help in reducing carbon emissions.
Ultracapacitors are now being applied to satellite technology and space travel. The aerospace industry is particularly demanding and requires extremely low-weight, high-performance technologies that can tolerate large temperature variations and exposure to radiation. Power-to-weight ratio is particularly important as the cost of sending 1 pound to space is around €9000 and reducing overall weight, and therefore cost, is a key target for the industry. Ultracapacitors offer a very high power-to-weight ratio, are robust under challenging conditions and offer long lifespan, making them ideally suited to the aerospace industry.
While spacecraft harvest their energy with solar cells, they do have to spend some of the time on the “night side” where they rely on stored energy. This function is currently undertaken by lithium-ion batteries. Although batteries can store more energy than ultracapacitors, they are slow to charge and discharge, lose 30% of their energy through heat alone and require frequent replacement. Ultracapacitors can charge almost instantly and deliver significantly more power for weight compared to batteries. Using ultracapacitors for tasks such as adjusting antennae and moving solar arrays will considerably reduce the amount of weight and room required for energy storage.
The motorsports industry has a key role to play in driving fuel efficiency and leading technological thinking for the automotive industry as a whole. The sector has become a test-bed for many of the common technologies we see in the automotive industry today, from disc brakes and rearview mirrors to engine air intake and the use of new materials like carbon fiber. Motorsports is an ideal environment to apply the new high-performance systems that ultracapacitors enable and to lead engineering advancements in vehicle performance and efficiency.
Kinetic Energy Recovery Systems (KERS) are an advanced technology used in modern racecars and high performance vehicles for recovering kinetic energy under braking. The recovered energy is then used to provide additional power and boost acceleration when needed while reducing fuel consumption. With recent advances in technology, ultracapacitors now provide one of the best technology solutions on the market for KERS applications.
“Ultracapacitor technology has the potential to increase mission safety while reducing mission costs. SpaceCap cells will allow us to package a large amount of power into a very small package, creating opportunities for new applications.”

Recycled furniture is an awesome DIY project, but as with everything online, you can always find someone taking it one step further. This time, it is a chair made out of an actual Boeing 737 jet engine.
The guys at the Fallen Furniture (perfect choice for a name) are making furniture and art pieces out of reclaimed, authentic aircraft parts, from both military and civilian aircraft. The centerpiece of the collection being a chair made out of Boeing 737 jet engine. It features a polished aluminum base and a black leather cushioned interior.
The quest to make your living room stand out might be finally over, but the last tricky bit is to get the chair. You’ll have to place a special order for which the price remains unannounced (we don’t expect a sale anytime soon). The other option is to make one yourself… if you have a jet engine lying around somewhere in your basement, that is. | aerospace |

Flight 5461, which was carrying 164 passengers, was diverted at around midday UK time after taking off at 7:25am for the Greek island of Crete.
The co-pilot then took over the controls and landed the plane safety at Marco Polo airport in Venice, Italy, The Sun reported.
Paramedics took the pilot to hospital after the plane landed.
The pilot remains in hospital, but is not in a life-threatening condition.
Passengers onboard the flight completed their journey to Heraklion airport in Crete after easyJet sent out a replacement aircraft.
A spokesman for the low-cost carrier confirmed to MailOnlinethat the flight was diverted “”as a result of the Captain requiring medical assistance.”
The incident follows two similar events in the US this week.
On Monday, pilot Michael Johnston, 57, fell ill mid-flight, and later died. His family later revealed that he had suffered a heart attack.
The flight heading from Phoenix, Arizona to Boston, Massachusetts was diverted to Sycaruse, New York, when the Mr Johnston was stricken.
A day later, the co-pilot of a plane heading to San Francisco, California, from Houston Texas fell ill.
That flight safely diverted to Albuquerque, New Mexico.
To ensure the safety of the passengers and crew, airline pilots are required to pass annual physical examinations, rising to every six months for captains 40 or older.
Only seven pilots for US airlines and one charter pilot have died during flights since 1994, according to the Federal Aviation Administration (FAA).
Steve Wallace, who led the FAA accident-investigations office from 2000 to 2008, said following Mr Johnston’s death that it was rare for a pilot to become incapacitated. | aerospace |

From: Antoine Couëtte
Date: 2021 Oct 10, 17:57 -0700
Hello to all,
On Friday morning Oct 8th 2021, in France and shortly before Sunrise, I happened to watch for a long time the condensation trail of a long haul Aircraft flying an easterly track. This "contrail" immediately followed the Aircraft and was very short, to an extent that - given our relative configuration - it was showing as a very bright slowly moving spot. I even thought of Mercury for a few seconds ... And by no means could I see the Aircraft herself since she was so far away.
This Aircraft - or at least its contrail - went all the way downwards until it became hidden by and behind my "local horizon" itself. As the result of the small elevation of some nearby terrain 3 miles away my "local horizon" in the Aircraft Azimuth shows slightly above my "true horizon" at an angular elevation which I accurately measured to be at 0.76° .
For fun, I decided to compute this Aircraft distance and I got a bit surprised at the results.
Interesting computation, and not utterly difficult.
Let "α" be the elevation of the "apparent horizon" above the "true horizon" and let "h" be the aircraft altitude in units of the Earth Radius which makes computations easier.
What is the Aircraft Distance "d" ?
(1) - Numerical example assuming that there is no refraction. With h = 42,000' (FL 420) and α = 0.76°, what is the oblique distance "d" - in Nautical Miles - of the Aircraft to the Observer ?
(2) - Same numerical example with the previous values and assuming this time that the refraction is equal to 19'. This refraction estimate seems a reasonable starting point since "full refraction" would be close to 26' if the Aircraft were outside the atmosphere at an infinite distance. A significant part of the atmosphere has been crossed obliquely from the Aircraft downwards to the Observer as the static Air pressure around the Aircraft is close to 1/4 of its sea level value.
Hope this has not been addressed in NavList before ...
Please publish your own solutions altogether with comments if any.
I will publish mine, altogether with pictures showing the unusual and funny manner I measured my local horizon elevation to be at 0.76° ... in a quite windy day yesterday.

Can the US claim the moon?
Outer Space, including the Moon and other celestial bodies is not subject to claims of national appropriation by claim of sovereignty, by means of use or occupation, or by any other means.
No-one, according to the Moon Treaty, can own the Moon or any part of it..
How far back in time can we see?
In actuality, we can see for 46 billion light years in all directions, for a total diameter of 92 billion light years.
Is there a Google Mars?
Hey, you! Want to explore the surface of Mars? … Just in time for the 2nd anniversary of the Curiosity rover touching down on Martian soil, Google has tucked 3D, explorable versions of Mars and the Moon right into Maps.
Does Google Moon?
Open Google Earth. Look at the icons just above the Earth image. Click on the one that looks like Saturn and select Moon from the dropdown. This will take you to Google Moon.
Can you see the flag on the moon from Earth with a telescope?
Yes, the flag is still on the moon, but you can’t see it using a telescope. … The Hubble Space Telescope is only 2.4 meters in diameter – much too small! Resolving the larger lunar rover (which has a length of 3.1 meters) would still require a telescope 75 meters in diameter.
Why can’t Hubble see the flag on the moon?
Since ultraviolet light is blocked by gases in the Earth’s atmosphere, ground-based telescopes can’t use it to observe the lunar surface.
Can you buy land on the moon legally?
Bottom line, there is nothing that expressly forbids companies from owning land on the moon. … Any documentation that claims you own land on the moon is unenforceable, and no nation on the planet that has signed either the Outer Space Treaty or the moon Treaty will recognize it.
Why did we stop going to the moon?
Apollo 17 became the last manned mission to the Moon, for an indefinite amount of time. The main reason for this was money. The cost of getting to the Moon was, ironically, astronomical.
How much is a ticket to Mars?
Tickets to Mars Will Eventually Cost Less Than $500,000, Elon Musk Says | Space.
Can you see the flag on the moon on Google Maps?
To celebrate the 40th anniversary of the Apollo 11 Moon landing, Google has launched a new feature: the Moon in Google Earth. If you click on the Apollo 11 flag, you can zoom in on that location and take a tour of the first landing site on the Moon! …
What is the farthest object in the universe?
Just under a month ago, the current candidate was this object: a young galaxy called MACS0647-JD. It’s only a tiny fraction of the size of our Milky Way – and was observed at 420 million years after the Big Bang, when the universe was 3 percent of its present age of 13.7 billion years.
What is the temperature on the moon?
Daytime on one side of the moon lasts about 13 and a half days, followed by 13 and a half nights of darkness. When sunlight hits the moon’s surface, the temperature can reach 260 degrees Fahrenheit (127 degrees Celsius). When the sun goes down, temperatures can dip to minus 280 F (minus 173 C).
Can the flag still be seen on the moon?
The flag of the United States, and no other flag, shall be implanted or otherwise placed on the surface of the moon, or on the surface of any planet, by members of the crew of any spacecraft … as part of any mission … the funds for which are provided entirely by the Government of the United States. …
How many countries have walked on the moon?
The United States is the only country to have successfully conducted crewed missions to the Moon, with the last departing the lunar surface in December 1972.
Who owns the moon?
The Outer Space Treaty means therefore that – no matter whose national flags are planted on the lunar surface – no nation can ‘own’ the Moon. As of 2019, 109 nations are bound by the Treaty, and another 23 have signed the agreement but have yet to be officially recognised. | aerospace |

Vertical takeoff and landing (VTOL) aircrafts such as helicopters and drones, add a flexible degree of operation to airborne vehicles. In order to operate these devices in low light situations, where it is difficult to determine slope of the landing surface, a lightweight and standalone device is proposed here. This small optical device can be easily integrated into current VTOL systems. An optical projector consisting of low power, light weight, solid state laser along with minimal optics is utilized to illuminate the landing surface with donut shaped circles and coaxial centralized dot. This device can placed anywhere on the aircraft and a properly placed fiber system can be used to illuminate the surface beneath the bottom of the VTOL aircraft in a fashion that during operation, when the aircraft is parallel to the landing surface, the radius between the central dot and outer ring(s) are equidistant for the entire circumference; however, when there the landing surface of the VTOL aircraft is not parallel to the landing strip, the radial distance between two opposite sides of the circle and central dot will be unequal. The larger this distortion, the greater the difference will be between the opposite sides of the circle. Visual confirmation or other optical devices can be used to determine relative alignment of the projector output allowing the pilot to make proper adjustments as they approach the landing surface to ensure safe landings.

Astronaut Randy Bresnik, who joined the NASA program in 2004, shared highlights of his trip to space, including docking with the International Space Station and eating in zero gravity.
He also urged his young audience to become good leaders.
"The most valuable leadership trait I've seen over my years in this environment is humility. It's not about you, it's about accomplishing your mission with the people around you," Bresnik said.
The astronaut was greeted by more than 300 students in the Sandy Beaver Center theater.
Students learned about Bresnik's 2009 shuttle Atlantis mission and how he walked in space twice to help replace systems parts on the space station.
Bresnik told the students he trained in water at the large NASA pool in Houston to simulate the space walk, which has a full-size mock-up of space station components.
"Anytime we reach for a tool, we've done it several times underwater so that it's executed flawlessly," Bresnik said.
He also made himself available for questions that ranged from, "How do you work out in space?" to "Why are space suits white?"
The answers: astronauts in space work out two to three hours daily on exercise machines to prevent the loss of bone density, and he wasn't sure why the suits are white.
"Maybe the U.S. government got a good deal on white fabric," he said. "The Russian suits are actually tan."
In response to a student's question about sleeping aboard the space station, Bresnik said sleeping bags are tethered to the wall. He also found some creative ways to rest.
"At first, I had my sleeping bag at normal orientation, so I would wake up and everything was where it should be," he said. "By the second or third night I put it on the ceiling."
Bresnik said he began his career as a pilot in the Marine Corps where he was promoted to lieutenant colonel before applying to the NASA program during a mission to Iraq.
"I never thought when I was growing up in Santa Monica, Calif., that I'd have a chance to do this," Bresnik said, as he pointed to a slide of his mission.
He told the students hard work and confidence can lead them to their goals, too.
"I learned that the only limits I had were the ones I put on myself," Bresnik said.
Student Paul Ribeiro, 18, said he wanted to become a pilot one day and was impressed with Bresnik's speech.
"I thought it was great when he said good leadership is something you try to emulate and bad leadership is what you learn from," Ribeiro said.
Bresnik said he has embraced the task of inspiring younger generations, which is one reason he accepted Riverside's invitation to speak. He said he also still trains for space travel and hopes to sign on for a long-term mission in the future. | aerospace |

They are so common, it’s easy to take for granted the incredible cultural access they afford us, and the unbelievable technology and engineering that goes into making them fly. Which raises the question: how do airplanes fly?
How does a metal tube weighing hundreds of thousands of pounds overcome the force of gravity and get 30,000 feet above the ground?
Airplanes, like everything else on earth, are kept on the ground by the downward force of gravity. In order to fly, airplanes must generate an upwards force stronger than gravity. This oppositional force is called lift.
While many parts of an airplane affect lift, most of the lift is generated from a simple shape, called an airfoil. Airplane wings are designed to create a difference in pressure between the top of the wings and the bottom of the wings. When a plane is parked on the ground, air molecules bounce off of the top and bottom of the wings in roughly the same amounts, with roughly equal pressure. However, when the plane is moving, the shape and angle of the wings splits the airflow in two directions: up and down. This forces more air molecules to bounce harder off of the bottom of the wings, which makes the pressure go up underneath the wings. At the same time, less air molecules are now bouncing off of the top of the wing, which lowers the pressure. In addition, the particles are moving across the top much faster than on the bottom, and as air speeds up, it’s pressure drops.
When the pressure underneath the wing is stronger than the pressure on top of the wing, the plane is able to take off into the air. As long as the upward force of pressure underneath the wings is greater than the downward force of gravity, the plane will be able to fly.
Airfoils are only able to generate this force when moving. If there is no motion, there won’t be any lift. It doesn’t matter if either the wing or air particles are stationary – a plane will still be able to fly on a windless day as long as it is able to generate motion. | aerospace |

The Kuiper belt (/ˈkaɪpər/) is a circumstellar disc in the outer Solar System, extending from the orbit of Neptune at 30 astronomical units (AU) to approximately 50 AU from the Sun. It is similar to the asteroid belt, but is far larger—20 times as wide and 20–200 times as massive.
What is the difference between Kuiper belt and the asteroid belt?
Asteroids are composed of metals and rock, whereas comets also contain ice and dust. The Kuiper belt is a collection of such bodies that orbits at the edge of the solar system.
What is Kuiper belt and asteroid belt?
The Asteroid Belt, the Kuiper Belt, and the Oort Cloud are all composed of remnants from the formation of the solar system. Currently there are 958,663 known asteroids and 3,645 known comets that orbit the Sun.
Are asteroids in the Kuiper belt?
The Kuiper Belt is a disk-shaped collection of asteroids (inset diagram) that floats within the far larger, spherical Oort Cloud of comets. The belt exists between about 30 AU, the outer edge of Neptune’s orbit, and 50 AU, where Neptune’s orbital resonance causes the number of objects to drop off rapidly.
Is the Kuiper belt before the asteroid belt?
Video quote: But astronomers struggled to see them in 1992 david jewett and jane liu discovered the kuiper belt.
Why is the Kuiper Belt called the Kuiper Belt?
The Kuiper Belt is named for astronomer Gerard Kuiper, who published a scientific paper in 1951 that speculated about objects beyond Pluto. However, he didn’t actually discover it. Putting together the data to officially recognize it and its components took many scientists many years.
What is the difference between asteroid and asteroid belt?
An asteroid is a small, rocky object and when seen in a telescope, it appears as a point of light. Most asteroids are found in a ring between the orbit of Mars and Jupiter called the asteroid belt.
Why asteroids are located in the asteroid belt?
Asteroids are concentrated in the asteroid belt because of orbital resonances between asteroids and Jupiter. Asteroids with orbital periods that are a simple ratio of Jupiter’s 12-year orbital period experience the same gravitational nudge on a regular basis.
What is the exact location of the asteroid belt in the solar system?
There are lots of asteroids in our solar system. Most of them are located in the main asteroid belt – a region between the orbits of Mars and Jupiter.
Do all solar systems have asteroid belts?
Full image and caption New observations from NASA’s Spitzer Space Telescope indicate that the nearest planetary system to our own has two asteroid belts. Our own solar system has just one.
Are there 2 asteroid belts?
The inner asteroid belt is a virtual twin of the belt in our solar system, while the outer asteroid belt holds 20 times more material. Moreover, the presence of these three rings of material implies that unseen planets confine and shape them.
What does the Kuiper Belt consist of?
There are bits of rock and ice, comets and dwarf planets in the Kuiper Belt. Besides Pluto and a bunch of comets, other interesting Kuiper Belt Objects are Eris, Makemake and Haumea. They are dwarf planets like Pluto.
Is the asteroid belt a failed planet?
Occasionally people wonder whether the belt was made up of the remains of a destroyed planet, or a world that didn’t quite get started. However, according to NASA, the total mass of the belt is less than the moon, far too small to weigh in as a planet.
What are the 12 planets name?
If the resolution is approved, the 12 planets in our solar system listed in order of their proximity to the sun would be Mercury, Venus, Earth, Mars, Ceres, Jupiter, Saturn, Uranus, Neptune, Pluto, Charon, and the provisionally named 2003 UB313.
What is the planet that exploded?
Flash! An asteroid or icy object collided with the gas giant Jupiter on Sept. 13, where it eventually blew up in the planet’s thick clouds. A Brazilian space photographer, José Luis Pereira, captured the rarely-seen solar system event, which is shown in the intriguing footage below.
What is the Kuiper Belt and where did these bodies form?
The Kuiper belt is thought to consist of planetesimals, fragments from the original protoplanetary disc around the Sun that failed to fully coalesce into planets and instead formed into smaller bodies, the largest less than 3,000 kilometres (1,900 mi) in diameter.
What is the asteroid belt called?
the main asteroid belt
This asteroid belt is also called the main asteroid belt or main belt to distinguish it from other asteroid populations in the Solar System such as near-Earth asteroids and trojan asteroids. The asteroid belt is the smallest and innermost known circumstellar disc in the Solar System.
What lies beyond the Kuiper Belt?
2. It’s far out. (But the Oort Cloud extends even farther) The Kuiper Belt shouldn’t be confused with the Oort Cloud, which is an even more distant, spherical region of icy, comet-like bodies that surrounds the solar system, including the Kuiper Belt.
How is the Kuiper Belt formed?
Kuiper Belt formation
When the solar system formed, much of the gas, dust and rocks pulled together to form the sun and planets. The planets then swept most of the remaining debris into the sun or out of the solar system.
What does the Kuiper Belt separate?
Detached Kuiper Belt objects have orbits that never come closer to the Sun than about 40 AU. This sets them apart from most other KBOs, which spend at least part of their orbits in the region between 40 and 50 AU from the Sun.
What is the difference between Kuiper Belt and Oort Cloud?
The Kuiper cloud, which is more commonly known as Kuiper belt, is a disk-shaped region that is seen beyond Saturn’s orbit. The Oort cloud is a mass of trillions of comets and dust that circle the sun. The Oort cloud is not really a cloud yet it extends three light years from the sun.
What is the Kuiper Belt and why is it important?
This ring is generally referred to as the Kuiper Belt. The Kuiper Belt holds significance for the study of the planetary system on at least two levels. First, it is likely that the Kuiper Belt objects are extremely primitive remnants from the early accretional phases of the solar system.
What is asteroid belt in solar system?
Bottom line: The asteroid belt is a region of our solar system – between the orbits of Mars and Jupiter – where many small bodies orbit our sun.
How many asteroids are in the asteroid belt?
The belt is estimated to contain between 1.1 and 1.9 million asteroids larger than 1 kilometer (0.6 miles) in diameter, and millions of smaller ones.
What is the Kuiper Belt located?
The Kuiper Belt is a disk-shaped region situated in the outer Solar System, which is past Neptune’s orbit. Its inner edge starts from Neptune’s orbit (30 AU from the Sun), and the outer edge goes to nearly 1.000 AU. Neptune is the farthest planet from the Sun, and as such, the Kuiper Belt is very far away from us.
Where is the Kuiper Belt and Oort Cloud located?
The Oort Cloud lies far beyond Pluto and the most distant edges of the Kuiper Belt. While the planets of our solar system orbit in a flat plane, the Oort Cloud is believed to be a giant spherical shell surrounding the Sun, planets and Kuiper Belt Objects.
How are the Kuiper Belt and Oort Cloud similar?
Located on the outskirts of the solar system, the Kuiper Belt is a “junkyard” of countless icy bodies left over from the solar system’s formation. The Oort Cloud is a vast shell of billions of comets.

Designed to combine both the bombing and torpedo functions previously performed by several aircraft in the postwar Navy, the AM-1 Martin Mauler was the only single-engine production aircraft powered by the massive 3,000 hp Pratt & Whitney R-4360 Wasp Major radial, air-cooled engine. Production models were powered by the more reliable R-3350 engine. The Mauler on display is powered by the R-4360 Wasp Major engine.
A prodigious weightlifter, it demonstrated a maximum useful ordnance load of 10,689 lbs. Production orders were placed in January 1945 for 750 of the AM-1 model and by 1949 several operational units were flying the AM-1. Though outstanding, only 151 were completed and production was terminated in October, 1949 in favor of the more advanced Douglas AD Skyraider after only 151 Maulers were produced.
The museum’s Mauler is one of only four surviving from an original production of 151. It was the 18th Mauler built and served at Jacksonville, St. Louis and Norfolk Naval Air Stations before being retired in 1955. Thereafter, it was transferred to the Army’s Aberdeen Proving Grounds in Maryland and used for weapons testing. Donated to the Bradley Air Museum in Connecticut in 1979, it was acquired by the museum in 1990. | aerospace |

Armstrong of the lunar module Eagle decended the steps and was the first person to physically touch the moon at 10:56 p.m. eastern daylight time, July 20, 1969. With that step came the historic words heard by an estimated 600 million television viewers, "That's one small step for a man, one giant leap for mankind."
Armstrong was joined later by Air Force Colonel Edwin E. "Buzz" Aldrin Jr. Together, with a camera rolling and the world watching, they placed a plaque which read, "Here men from the planet Earth first set foot upon the moon July, 1969, A.D. We came in peace for all mankind." The men then planted an American flag made of metal on the lunar surface, stepped back, and saluted.
The entire flight from Cape Kennedy, Florida in the command ship Columbia and it's attached lunar module Eagle took three days. (The two individual space modules were collectively named Apollo 11.) Upon establishing orbit, Armstrong and Aldrin donned white pressurized suits and, leaving the third member of the party, Lt. Colonel Michael Collins, on the Columbia began their descent. The descent to the moon was originally going to be automated, however due to mechanical problems and the fact that they were headed toward a rocky landing site, Armstrong gained manual control and directed the module to a safe landing site in the Sea of Tranquility.

https://www.italiani.it/helicopter-a-tricolour-symbol-truly-italian/ | 2022-07-07T16:30:12 | s3://commoncrawl/crawl-data/CC-MAIN-2022-27/segments/1656104495692.77/warc/CC-MAIN-20220707154329-20220707184329-00411.warc.gz | 0.978749 | 920 | CC-MAIN-2022-27 | webtext-fineweb__CC-MAIN-2022-27__0__39739759 | en | Helicopter means Italianity! The one who laid the foundations for designing this vehicle was Leonardo Da Vinci in 1486, to be precise.
The greatest artist and inventor in history, he designed a flying machine with revolving wings, thanks to the idea of the propeller; however more water under the bridges, and I would say clouds in the sky above all, were supposed to pass.
Helicopter really means Italianity, even though many abroad claim the paternity. The invention of the helicopter is tricolour! Regarding the world of flight, the inventions of the airplane and helicopter, although coming from a common history, they had parted ways. The study of flight by two wings continued in one way; while the one that provided for the operation of a higher propeller had other tortuous developments.
With some certainty, in this regard, we can say that the first that can be classified as a real helicopter, even if embryonic, dates back to the end of the nineteenth century. The ancestor of our modern helicopters, is undoubtedly the one developed by the Italian engineer Enrico Forlanini in 1877. All the aircraft at the time were delicate, just think that at the beginning the planes were wooden, very unstable and very fragile. The prototype of the engineer Forlanini was a small aircraft with a steam engine weighing about three kilos.
Corradino D’Ascanio and the helicopter
The helicopter of Forlanini managed to rise up to about 13 meters from the ground, but its steam structure did not allow much autonomy or pilot. We will have to wait until 1907 to see a bizarre aircraft equipped with a pilot lift off the ground. That year, Paul Cornu made another prototype with pedals, which operated rotating propellers, but it was almost a toy.
This prototype had no future, in fact, it rose from the ground only about thirty centimeters, and then fell down ruinously. In short, from the time of Forlanini, they were stalling, if not dropping into recession. The only helicopter’s father is Corradino D’Ascanio. The brilliant inventor has gone down in history for having conceived the Vespa, which has had a global success with few precedents. Born in 1891, he dreamt of flying since childhood, and he was attracted by aeronautical science, which was to the very beginning.
Enrolled at the prestigious Royal Institute of Engineering in Turin, he graduated in 1914 and few were able to keep up with his futuristic ideas. Perhaps D’Ascanio was too far ahead of its time. In 1906, after the Wright brothers’ flight, he designed and tested a sort of hang glider and made it fly successfully in the Abruzzo hills. During the war Corradino D’Ascanio installed the first radio on a vehicle and contributed to the modification of dozens of biplanes.
For him the flight was really an obsession. The successes of this visionary inventor have been numerous, but he did not always find an open mind, capable of supporting him. Evidently the time was not yet ripe. D’Ascanio’s “helicopters” to irrigate the fields are also brilliant. They are the ancestors of today’s drones, in which at first no one believed.
Ugo Veniero D’Annunzio
One of the winning strategies of the engineer D’Ascanio was undoubtedly that of opening a company together with Ugo Veniero D’Annunzio; an engineer, son of Gabriele. Thus a small aircraft was born on which the engine of a Harley Davidson was mounted. In those years he built many structures and patented some new inventions. Finally, one day, the first fully functional Italian helicopter took off on the Ciampino airport runway.
It was the D’AT3, designed and built entirely by the genius of Corradino D’Ascanio, and led by Major Marinello Nelli. It was October 8, 1930, and the Italian “flying machine” won the record in flight duration of 8′ 45”; the tenth record of distance with 1,079 meters in a straight line, and the thirteenth in absolute. The event had great prominence in the press, especially that of eighteen meters in height; records that will remain unbeaten for some years. | aerospace |

Although the process does compete with conventional forming processes, applications are being discovered were laser forming alone can achieve the desired results. The application reported in this work demonstrates how the process can be used to form recently developed high strength metal laminate composite materials, these materials due to their construction and high strength are difficult to form once constructed using conventional techniques. Metal laminate composite materials are of particular interest to the aerospace industry, were the high strength yet lightweight construction of parts made with these materials offers significant weight reductions and hence a reduction in operational costs of new large commercial aircraft such as the Airbus A380. Also reported in the work is a system for the closed loop controlled 2D laser forming of such components. | aerospace |

Does space have a smell?
In a video shared by Eau de Space, NASA astronaut Tony Antonelli says space smells “strong and unique,” unlike anything he has ever smelled on Earth.
According to Eau de Space, others have described the smell as “seared steak, raspberries, and rum,” smokey and bitter..
How much do astronauts get paid?
Astronauts’ annual salaries are determined using a government pay scale, and starting out, typically fall under two grades: GS-12 and GS-13. According the US government’s 2020 pay scales and a NASA job listing, a civilian astronaut in 2020 can earn between $66,167 and $161,141 per year.
How fast can human travel in space?
The current human speed record is shared equally by the trio of astronauts who flew Nasa’s Apollo 10 mission. On their way back from a lap around the Moon in 1969, the astronauts’ capsule hit a peak of 24,790mph (39,897km/h) relative to planet Earth.
Can a spaceship stop in space?
Space ships do not stop when they run out of fuel. While outer space does contain gas, dust, light, fields, and microscopic particles, they are in too low of a concentration to have much effect on spaceships. As a result, there is essentially zero friction in space to slow down moving objects.
Can you accelerate indefinitely in space?
As long as you have useable energy in your ship, you can use it to accelerate indefinitely your propellant in the opposite direction you want to accelerate; this is how rockets work.
Is it possible to stay still in space?
Yes, it is possible to be essentially standing still in relationship to the Sun. There are many comments and an answer telling you why you can’t and, as far as they go, they are correct. If you move far enough away from our sun, it become just another star.
What happens if you throw a ball in space?
In deep space, far enough away from large objects like stars and planets that gravity may be neglected, a thrown ball will travel in a straight line and the person throwing the ball will also travel in a straight line in the opposite direction. … The lighter object moving faster.
How much does a space suit cost?
The cost of a spacesuit originally was about $22 million. Building one from scratch right now can be as much as 250 million.
Why do things go so fast in space?
Gravity is why stuff is moving very fast. It’s all about the frame of reference. You are moving at the same extremely high velocities from the point of view of these outer space objects. It’s just that everything around you is moving to a similar speed as yours.
Can you swim in space?
2 Answers. You can sort of swim, but it would be very slow. The viscosity of air vs water is very low. Therefore the ‘scoop’ your hands or feet can get of the fluid, to propel it, and thus move you around would need to be much higher.
Is there wind in space?
In space there is no air, so no wind as per the common definition. However, there is something called solar wind. Solar winds are streams of particles emitted from stars, including our sun.
Does inertia exist in space?
Absolutely yes! Even in space objects have mass. And if they have mass, they have inertia. That is, an object in space resists changes in its state of motion.
Does a spaceship need fuel in space?
Why do rockets need so much fuel if, in space, there is nothing to slow them down once they are up to speed? Robert Frost: The propellant is primarily needed to get the spacecraft into orbit, not to stay in orbit. … When about half the propellant is burned, the bottom half of the rocket is jettisoned.
Has anyone been lost in space?
A total of 18 people have lost their lives either while in space or in preparation for a space mission, in four separate incidents. Given the risks involved in space flight, this number is surprisingly low. The two worst disasters both involved NASA’s space shuttle. | aerospace |

FreeFall Aerospace – Inflatable Antenna
Space antennas direct data to the right ground station or device on the ground. However, they are usually large and expensive to put into orbit. Low mass and low power alternatives generally also have low data rates. Inflatable reflectors offer high data rates without the mass and complexity of traditional solutions, enabling modern applications such as fifth-generation (5G) wireless.
The US-based startup Freefall Aerospace develops antenna technology for use in ground, air, and space. The startup’s inflatable antenna for spacecraft systems is ultra-low mass and volume. The antennas have spherical reflectors and large apertures for wide fields of view and high gain. The solution uses electronic beam steering to transmit big data from CubeSats and small spacecraft. | aerospace |

The Antonov-32 aircraft had taken off from the southern city of Chennai in the morning and was heading for Port Blair in the Andaman and Nicobar Islands.
The aircraft departed around 8:30 am (0300 GMT) and was to have landed some three hours later, air force spokesman Anupam Banerjee said.
Officials said the last contact with the plane was around 15 minutes after take-off.
A search operation was launched by the Indian Navy, Air Force and the Coast Guard around the island group, located some 1,200 kilometres off the Indian mainland in the Bay of Bengal.
Navy spokesman DK Sharma said five maritime reconnaissance aircraft and an equal number of ships were deployed to carry out search and rescue operations.
"A very, very unfortunate news is coming out that one of our aircraft bound for Port Blair, has not reached there yet. It is missing. We will term it overdue," he said.
"The Navy has launched full-scale SAR (search and rescue mission). We hope for the best".
The aircraft can fly for up to four hours without refuelling. They have an emergency beacon locator, which usually gets activated if the aircraft crashes, broadcaster NDTV reported.
Antonov transports have been a mainstay of the Indian military. The Indian Air Force operates 100 of the planes. | aerospace |
