Amazon.com, Inc AMZN Chair Jeff Bezos will fly onboard Blue Origin’s “New Shepard” spacecraft, and accompanying him would be an 18-year-old Physics student. What Happened: Bezos-backed Blue Origin said in a statement that Oliver Daemen will be its first paying customer. As per the company, Daemen and Wally Funk, Age 82, would represent the youngest and oldest astronauts to travel to space on July 20. Daemen takes the place of an anonymous winner of Blue Origin’s auction who has “chosen to fly on a future New Shepard mission due to scheduling conflicts,” as per the space tourism company. Bezos will also be joined on the flight by his brother Mark Bezos. Why It Matters: The anonymous person who was originally scheduled to fly with Bezos bid $28 million to fly on New Shepard. Daemen’s father is the founder and CEO of the investment management firm Somerset Capital Partners Joes Daemen. Bezos was beaten to space by Sir Richard Branson, who flew onboard Virgin Galactic Holdings Inc’s SPCE Unity 22 spacecraft on July 11. Tesla Inc TSLA CEO Elon Musk who also heads SpaceX has booked a ticket with Virgin Galactic. SpaceX is also scheduled to launch a private astronaut mission in September. Price Action: On Thursday, Amazon shares closed 1.37% lower at $3,631.20 in the regular session and fell another 0.21% in the after-hours trading. Photo: Courtesy of Blue Origin © 2023 Benzinga.com.

A three-man crew took the torch up to the International Space Station on Thursday. Today, astronauts Oleg Kotov and Sergei Ryazansky tethered the unlit torch to their space suits while doing routine maintenance. The historic spacewalk was recorded using helmet cameras. The torch, which represents international cooperation, has been carried to space twice before. This was its first time leaving a spaceship, however.

- PHOTOS - Seven Bulgarian F-16s are in various stages of production, - GALLERY AND VIDEO&: THRACIAN SENTRY 2023 WITH BULGARIAN AIR FORCE - NATO is sending F-16s to Bulgaria for the Thracian Star 2023 exercise - Bulgarian Air Force L-39s to be modernized and overhauled - Dutch F-16s back to Europe (and go to Bulgarian AF?) - Interim fighters for the Bulgarian Air Force - Spain to join NATO's enhanced Air Policing mission in Bulgaria - Bulgaria celebrates 50 years as a spacefaring nation - EDA’s European Spartan Exercise cleared for take-off in Bulgaria - Breaking: Bulgarian Su-25 crashed On 13 December 2022, the Koninklijke Luchtmacht (KLu, Royal Netherlands Air Force) started to return former "US based" F-16 Fighting Falcons back to Europe. Six F-16s arrived at Lajes Field on the Azores (Portugal) in the dark hours. In total eleven F-16s are expected to return to Europe. The fighters will continue their journey on Thursday 15 december to Gosselies (Belgium), where they will be overhauled by Sabena Aerospace. This batch of eleven fighters was earlier reported as sold to Draken International, a provider of tactical fighter aircraft for contract adversary air (ADAIR, also known as “Red Air”). Some of the former KLu F-16s were already noted making some test flights late November/early December at the company's home base at Lakeland Linder International Airport in Lakeland (FL). Although the Dutch Ministry of Defence (MoD) still reports that the aircraft are sold to Draken International, strong rumours indicate that these F-16s will go to the Bulgarski Voenno Vzdushni Sili (BVVS, Bulgarian Air Force). Even more F-16s will come from the storage in the Netherlands and will join the F-16s now returning to Europe. Most probably the US government helped to cancel the contract with Draken International. NL KLu F 16 delivery to Lajes Jaoa Toste 3 320 NL KLu F 16 delivery to Lajes Jaoa Toste 2 320 Bulgaria has ordered sixteen Lockheed Martin F-16 Block 70 multi-role fighter aircraft, but deliveries are delayed for a period of two years. Because the Bulgarian MiG-29s will become unserviceable from late 2023 onward, the air force is in need for an interim fighter aircraft to replace the ageing MiG-29 fleet. On 24 November, Scramble Magazine reported on the interim fighters for the Bulgarian Air Force. The six F-16s that arrived in the evening hours of 13 December are: F-16AM: J-004, J-010 and J-018 F-16BM: J-064, J-067 and J-210

The British company Arc Aero Systems has presented a project for a new hybrid helicopter. The main task of the project is Photo: Arc Aero Systems The glider is a cross betweenairplane, helicopter and autogyro - rotary-wing aircraft. The all-composite construction weighs only 1,930 kg without weight. The nine-seat cockpit is similar to that of a helicopter, but features a thin 12.6 m long main wing with a pair of 2 m pusher propellers at the rear, as well as a large tail wing and fins. The large 13-meter top rotor is not connected to the tail rotor. The Linx P9 also uses an electric motor that spins the top rotor fast enough for vertical takeoff and landing. Various interior options Linx P9. Photo: Arc Aero Systems After takeoff, pushing propellers are turned on, and, asonly the speed increases, the wings take on more than 90% of the lift, and the top rotor can be immediately slowed down. This reduces drag and also eliminates the asymmetric lift that is seen in helicopters due to blade shedding. As a result, the Linx P9 has a maximum cruising speed of 370 km/h. Similar results were observed with the Sikorsky X2 twin-rotor coaxial helicopter. A giant sunspot is turning towards the Earth. It is visible to the naked eye See how a bladeless plane flies.

TRAPPIST-1 Planets 40 Light Years Away, But Will We Ever Reach There In Our Lifetime? If you’re a fan of science fiction, you already know how all that galactic travel is taking place. Some unimaginably simple science (fiction!) that makes the spacecraft travel large distances at ultra high speeds, bending the fabric of space and time. Star Trek’s USS Enterprise could travel at Warp 9 when required, though used to cruise at Warp Factor 1. That’s faster than the speed of light. It works when matter and anti-matter meet in presence of some dilithium crystals and the result is ejected by the engines. Although Scotty had a lot to do with the thing working properly and those dilithium crystals were a rare commodity. Then there was the Sakharov Drive in Arthur C Clarke’s ‘2010 Odyssey Two’. It used ‘pulsed thermonuclear reaction to heat and expel virtually any propellant material’. Spaceship Cosmonaut Alexi Leonov was able to reach Jupiter and find Dave Bowman and Discovery. But in 2017, we’re still stuck with rockets that burn kerosene, hydrogen, hypergolic propellants etc. The fastest we have really ever gone is 58,000 km/h when the New Horizon probe was launched on top of the Atlas 5 rocket. Although most interplanetary probes have had to rely on gravity assist to gain speed! It requires the spacecraft to approach a planet at such an angle that it is pulled by the gravitational force. This leads to an increase in the speed of the spacecraft which then slingshots its way forward. In the process of spacecraft gaining speed, the planet loses an equal amount of energy! But rocket fuels are not the only thing we have tried. Back in the 50s, NASA scientists looked to use the then new-fangled nuclear power to propel interplanetary rockets. But fear from the fallout of such a propulsion system and the following test ban treaties put rest to this. Thankfully. The next generation propulsion technique has been developed by NASA, called the ion-thrusters. Here, the thrust is created by accelerating ions with electricity. NASA’s Deep Space 1 spacecraft used the NSTAR ion thruster that utilised xenon fuelled engine with high-voltage electrodes to accelerate the ions. Currently, there are satellites in space that use ion-drive to stay in their respective orbits. Future plans include using the sun’s energy to push a spacecraft with a paper thin sail. Also on the drawing boards is the beamed propulsion tech that will supposedly let a spacecraft ride a laser. Then there’s Mexican scientist Miguel Alcubierre whose Alcubbierre drive uses Einstein’s theory of relativity to allow the spacecraft to travel faster than the speed of light. But all of this, at the current pace of development, may still be a few hundred years away. Till then, ‘Warp factor one Mr Sulu’.

The first RAF pilot to have his life saved by an ejection seat was our Dad, Bill Tollitt. On July 3rd 1951, when he was serving with No 65 squadron at Linton-on-Ouse, Bill’s Meteor collided with another aircraft and went into a tight inverted spin. In his last moments of consciousness, Bill managed to activate the ejection seat and he was ejected downwards. He felt himself tumbling through the air. It was a manual seat, and because he was disoriented and his fingers had lost all feeling, Bill was unable to release himself from the seat. With numbed hands he managed to pull his parachute ripcord, and because his seat had been damaged in the process of ejection, the parachute was able to emerge. A farmer saw the aircraft crash into a field and then saw a parachute with a man in a large seat descend in the next field. The farmer thought that the pilot was dead and dashed off to phone the RAF base. When he returned he was surprised to find Bill alive. Bill had fractured his skull on landing, had frostbitten fingers and bruised eyes. He spent a week in hospital. His twin sister Monica Beckett, remembers hitch hiking from Marlborough when she was told about the crash and visiting him in hospital. She has told us that Bill was also visited in hospital very soon after the crash by James Martin, founder of Martin-Baker. Bill went on to fly in the Canadian Air Force and then for Cambrian Airways until he sadly died from cancer in 1968 at the age of 40. Bill’s three children and five grandchildren would not be here today were it not for the ejection seat. He has a son and a granddaughter who are commercial pilots, we are all grateful that his life was saved that day. Thank You.

2002(ish) - The Flailing Firebird I finally broke away from work and headed down to the LHS to talk about this guy I saw sloping at the beach. They let me borrow some thermal soaring VHS tapes. So cool! I wanted to fly with the birds too! I knew a few guys that were flying Zagis but I made the mistake of buying an electric planes to learn with. HobbyZone Firebird XL - I did have some fun with this plane but I learned that it was a waste of money. I would sped about a minute flying it and hours fixing it. Very sensitive to wind, more difficult to repair than a foamie, etc. It flew like garbage. I eventually gave up on the plane and the hobby. Sad. I would never recommend this plane to anyone. |Category||Thread||Thread Starter||Forum||Replies||Last Post| |Yippee!||MSR Outdoor Buzzin' - More of the "FP-ish" and less of the "Coax-ish"||EQMOD||Micro Helis||10||Apr 24, 2010 06:52 PM| |Sold||Kyosho Caliber 90 (2002 version) brand new||pttse||Aircraft - Fuel - Helis (FS/W)||0||Mar 08, 2010 04:57 AM| |Discussion||Which is better the hobbyzone firebird pandtom or the firebird scout ?||mortonj69||Parkflyers||1||Nov 04, 2009 10:38 AM| |Discussion||Newbie flailing on first build, grateful but not dead||renne2k||Electric Plane Talk||4||Jun 16, 2007 08:20 PM| |I got mine..

The US Air Force wants Silicon Valley, the defence industry and the Pentagon to help develop electronic cloaking technologies to help make aerial tankers less visible to enemies. In Star Trek, the Romulans were well known for developing cloaking devices – an energy screen that by selectively bending light and other energies rendered spacecraft completely invisible to the electromagnetic spectrum and most sensors. Now the US Air Force has decided that it wants cloaking devices in order to hide its aerial tankers, which fulfil a vital role in refuelling jet fighters in mid-air, and to that end it has been consulting with the Defense Advanced Research Project Agency (Darpa), military service laboratories and defence contractors. The idea is to alter the waveform of the aircraft so that it either appears to be in a completely different location to where it actually is on an enemy radar system, or to cause the aircraft to completely disappear. "I've got airplanes with big fat bodies and long wings. I've got first-generation tankers refuelling fifth-gen fighters. The enemy doesn't have to look for the fighter – he just has to look for me," General Carlton Everhart, head of the Air Mobility Command told Bloomberg. "I asked industry for a cloaking device and they all laughed. They said, 'You've been watching too much science fiction.' I said, 'Listen to me – this is what I want: something that would be able to change the waveform.'" Everhart says he has had to go to the tech industry, because if he just left it to the military acquisition system it would take about 50 years before the solution could be deployed, as it would have to go through a great deal of regulations first. The Air Mobility Command currently flies 40% of all the refuelling missions over Iraq and Syria for jet fighters battling Islamic State. In 2014, there were 29,000 aerial refuelling operations when US intervention first began, and in 2016 there were 81,000 refuelling operations. Everhart is also thinking about how the tankers can be of better use to defend themselves and other aircraft in the air, and to that end he is keen to equip the aerial tankers with laser weapons that can completely destroy any ground-to-air missiles, rather than just using lasers to blind missile warheads. In 2016, the aerial tankers of the Air Mobility Command flew the equivalent of 66 years. "Everyone says this is a shooting war, but we are providing them all that gas," he said.

Great flight. Easy peasy. Safe. And nice crew. Thank you! Pros: "Professional crew, no fanfare, standard was excellence." Cons: "Faster flight time in air..." Cons: "There is always just too much talking and announcements on the flights now." Cons: "Delta flies a lot of the CRJ planes, even on relatively longer trips. Traveling first class, the seats are a little wider than in coach and have a little more leg room, but calling it "first class" is a bit of an exaggeration. It's more like what coach used to be before the days of the flying sardine cans." Pros: "The crew was awesome! The steward was engaging and made us all laugh and feel comfortable for a short flight when he didn’t have to. He had a great sense of humor and gave the kids cookies and wings. Something I haven’t seen in many years. He and the pilots were great!" Pros: "Great service" Cons: "Messed up my luggage in Atlanta. Gate said baggage was going to domestic. Ended up in international terminal. Added almost an hour of back and forth between terminals." Pros: "Good experience" Cons: "Better snacks" Cons: "I’m skinny and 5’2” and I felt squashed. Like I was in a dollhouse. The space is too small, it’s too uncomfortable. I couldn’t take my zip front sweater off. The seats and space are not proportional to humans." Pros: "Not much" Cons: "Being on time. Trapped in plane for 2 hours" Cons: "Flight left on time and arrived 30 minutes early! Great crew. No complaints here!" Pros: "Standard boarding The plane was on time" Cons: "Better boarding process.Such as the one used by Southwest" Pros: "On this short flight, the flight attendant was wonderful, accommodating special requests and being fully engaged with passengers. On time departure, early arrival, overall a nice quick flight to Duluth." Cons: "CRJ200 planes are always a bit cramped, and having to gate check anything bigger than a small purse is an inconvenience. Hopefully the fleet will change over to the Embrair planes soon. Beware 'Basic' flyers (cheap tickets): you are not eligible to take an earlier flight even if available." Pros: "Matt was great. I had an exit row so it was comfortable." Cons: "Deplaning takes FOREVER" Pros: "I was originally booked through jfk with an 80 minute layover. When I told a delta.help desk employee i feared it was too tight (I flew out through jf k and that was enough to convince me...) he booked me through Atlanta with a.comfortable schedule. Thank you!" Pros: "I had a very comfortable seat, it was a very good experience overall." Cons: "Unfortunately had flights delayed which forced me to arrive home much later than originally planned." Pros: "Good seating, great food, good service." Pros: "We eventually got to Atlanta." Cons: "Delta is flying a lot of commuter planes, which are pretty cramped. We usually fly first class, and the seating is essentially the same as what coach used to be. There's nothing "first class" about it. And of course, the flight was hours late." Pros: "Crew was amazing." Cons: "Delayed departure due to late crew arrival. Not a huge deal." Pros: "Zee was our flight attendant and she was absolutely wonderful. Personable, attentive, and she made sure each and every person on the plane was comfortable and happy, going so far as to move solo passengers to empty rows so they could have more space. I wish she could be on every flight I take." Pros: "I was rerouted through Detroit after it was apparent I would miss my connecting flight. The flight was good and I have no complaints." Pros: "Take off on time, arrived early, pleasant flight attendant" Cons: "Had to sit on tarmac after arriving early" Pros: "On time, pleasant and friendly flight attendant, no unexpected issues or problems." Cons: "Grumpy gate attendants at YUL! Could not hear the captain’s comments over the PA system. Shouldn’t the volume be checked every so often? We were offered only water or coffee, bad enough, then there was no milk or cream on board, so water or black coffee... not very impressive! And there was no entertainment so I’d rate that zero but the scale only goes as low as one star." Cons: "Boarding was a little bit rushed and the gate agent was visibly irritated by some passengers who didn’t check their bags." Pros: "It's a fast flight and boarding was quick." Cons: "The terminal at LGA airlines is terrible." Cons: "Customs never to hire more agents to work in the early mornings." Pros: "On time, and pleasant flight. Flight attendants were first class: very competent." Cons: "I slept all the way, so can’t say whether anything went wrong with the flight." Pros: "Nice flight nice crew just about as good as you would want" Cons: "Mechanical repair on nose wheel" Pros: "Everything was great." Pros: "Friendly crew with the usual high quality Delta product..." Cons: "Premium passenger's should be boarded before families with children! Especially in Orlando where half the plane is children!" Pros: "Not applied" Cons: "Not applied" Pros: "We got on the plane and it went to where it was supposed to go." Pros: "Over all everything specially we got in earlier than expected" Pros: "Crew member Lori was exceptional. Great detail to safety and customer service!" Pros: "I got upgraded to comfort + which was great. quick flight, was even early" Pros: "Fligth were on time" Cons: "My flight from Montreal to Atlanta was 2:30 min Left at 6:10 arrive at 8:30 roughly Tried twice to get to my connection earlier and get 9:30 instead of 12:09 fligth to Daytona Delta was not flexible to allow me to book saying i did not have 55 min in between fligth which i had than lear n it will cost $75.00 to change the fligth - What? Very disappointed of Delta - lost 3 hrs at the airport today" Pros: "Couldn’t find a thing." Cons: "My husband booked West Jet by phone. They spelled my name wrong on the ticket which caused hours of delays tryng to check in...ultimately leading to our missing the flight. The time spent was around 6 hours....4 of them the were on one continuous phone call where we were bumped back and forth between West Jet and Delta. The problem was never fixed and we haven’t flown home yet. We have new flights booked on Delta but only because Delta took pity....West Jet does no refunds or reticketing. If flights are missed you're out on of luck!" Pros: "2 Delta employers went out of their way to address our messed up situation and make sure we got home without robbing us blind." Pros: "Flight was delayed by 2+ hours, Delta (running the flight for westjet) sent 1 email about the flight being delayed to 4:45 which was inconsistent with the gate signage and agent who said 3:45, flight ended up leaving at 5:45PM. No reasons were provided beyond the incoming flight from LGA hadn't come in. Why hadn't it come in? When could we expect to leave YUL? No answers." Pros: "Delta automatically rebooked our flight due to delays. We were rebooked on Air Canada" Cons: "Plane kinda of old. Just cookies and coffee" Pros: "Easy ride back home." Cons: "Limited options for closed captions video. Any announcement was not mentioned in writing." Pros: "Liked seating in Delta Comfort w own space for carry on and earlier boarding. Staff was attentive snd friendly and offered many snacks. Good choices for tv. Should option of getting head phones as I had the wrong one. Comfortable" Cons: "Should have one free luggage for Delta Comfort. More variety of food to purchash" Cons: "Seats are very small." Pros: "The flight attendant. Lovely and professional." Pros: "The crew & my seat" Cons: "The movie offerings & the snack offerings." Cons: "lack of carry on luggage space. very tight. gate agents did not care about the customers. I had to stick my bag under the seat and only half would fit so my feet did not fit with my bag. it was a back pack. I do not prefer checking luggage since I've had so many bad experiences."

Twice the rms effect of gravity coefficients above 12th degree and order on the computed orbit of a satellite at a height of 6-0 nautical miles is found to be less than 23 meters during a 24 hour period provided that (1) the rms of the gravity coefficients of degree n obeys the observed decay law of 10 to the minus 5th power/n squared for fully normalized coefficients, (2) resonance effects on the orbit are ignored and (3) the gravity coefficients up to the point of truncation are perfect. Under the same conditions, twice the rms effect decreased to 4 meters for a 600 mile orbit with 20th degree truncation. The maximum increased to 120 meters for a 200 mile orbit with 12th degree truncation.

By William Harwood CBS News August 11, 2018, 5:29 AM Parker Solar Probe launch delayed until Sunday The launch of NASA's $1.5 billion Parker Solar Probe atop a heavy-lift Delta 4 Heavy rocket was scrubbed at the last minute early Saturday because of a technical glitch that could not be resolved before the launch window closed. NASA and rocket-builder United Launch Alliance plan to make another attempt to get the long-awaited mission off the ground Sunday at 3:31 a.m. EDT (GMT-4), the opening of a 65-minute window, assuming the problem is corrected by then. Forecasters are predicting a 60 percent chance of acceptable weather. The Delta 4 Heavy's countdown ran into problems before fueling late Saturday, prompting ULA to delay the launch from 3:33 a.m. Saturday to 3:53 a.m. Then, inside of 10 minutes to launch, a hold was ordered due to problems with a data stream from the rocket. The countdown finally came out of a built-in hold at the T-minus four-minute mark, ticking toward a launch attempt at 4:28 a.m. when an engineer called out "hold, hold, hold" at the T-minus one-minute 55-second mark. The problem with a helium pressurization system could not be resolved in the 10 minutes left in the launch window, forcing ULA to order a 24-hour delay. "The team received a gaseous helium reg pressure alarm that kicked them out," said Mic Woltman with NASA's Launch Services Program. "The team is evaluating that. Unfortunately, we didn't have enough time this evening to go troubleshoot that and try again for a launch. So we're going to plan for a 24-hour turnaround." The Parker Solar Probe is the most ambitious sun-study spacecraft ever built, designed to repeatedly fly through the sun's outer atmosphere, or corona, to learn more about the mechanism that heats it to millions of degrees and accelerates charged particles in the solar wind to supersonic velocities. The powerful Delta 4 Heavy and a solid-propellant upper stage will provide the energy needed to counteract Earth's 18-mile-per-second orbital velocity, allowing the Parker Solar Probe to fall into the inner solar system. Once on its way, the spacecraft will fly through 24 elliptical orbits around the sun, eventually passing within just 3.8 million miles of the star's visible surface, enduring temperatures of 2,500 degrees as its instruments collect data from the closest vantage point ever attempted. © 2018 CBS Interactive Inc.

Supermarine PB31.......Crashed on take-off. Repairable.....I must remember--don't reduce take-off power until level flight established....Elevator response is poor when propwash is slow. Tu95. As designed, the engine nacelles were attached to the wing with a complex arrangement of hidden rubber bands, which required frequent replacement. Bands now replaced with thin soft steel wire: much less trouble. "Knockoffability" proved to be unnecessary. EE Lightning. "Lost it" twice on a recent flight, but managed to recover. At a distance, and at some angles, it's just a "blob" with no orientation clues.I am revising my landing drill, so that the final turn is as close as possible. Canberra. In flight, the black shows-up well, but the light grey can disappear. SIAI Marchetti 74. Three years since its last outing. I thought there was no need to keep notes, since the Tx remembers the trim settings. But I couldn't remember whether to use full rates or half for take-off. Too much is better than too little, so I chose full. Violent overcontrol! Urgent switch to half rates. P61. Must re-balance the props! Avro Lancastrian. Five years since its last outing. Last time I flew the Valiant [6 months ago] I lost control on the landing approach. Now, I am careful to arrange correct positioning of the 2.4GHz receiver antennas. Handley Page 0-400. First test after re-motoring with brushless. Just managed to struggle off our grass strip. New tail planned. Increased area to improve control. Ultra-light to reduce nose ballast. Skytruck. Based on the RCGroups Cargo Twin plan. Incredibly light and slow, 8 oz/sq ft. Just right for me! Ilyushin 28. Balsa wing and tailplane. Remainder Depron. F84, pushprop. A nice'n'easy flyer. Short Calcutta. Just re-maidened with electric power. First flight with glow power was 1989. Hair-raising first flight. Due to a combinaion of excessive throws, and my slow reactions. Survived, by good fortune. Second flight much better. Reduced throws, and expert pilot John Higgins on the sticks. Trimmed out nicely. The H6k is 19 years old, still flying well with speed 400s. Short L17. I'm still trying to find a safe landing technique. Absolutely essential to keep a bit of power on. My B36 has been flying since 1992, with an OS10 in the tail. Now converted to electric. One 60 gram outrunner, 1500 Kv. A much better flying experience. SeaDart. To vleisie's clever design, with a few superficial mods.

Mar 14,2008 00:00 Moratorium on Inspections Could Have Negative Business Impact BEND, Ore. -- Economic Development for Central Oregon Executive Director Roger Lee called on the Federal Aviation Administration (FAA) to avoid actions which would threaten Central Oregon's thriving aviation manufacturing industry. For more than twenty years, experimental class (also called kit) aircraft manufacturers have constructed the fuselage, wing skins, horizontal skins and spars which are provided as parts in the assembly of an aircraft. Over time, the industry has evolved, using machined aluminum, carbon fiber and composite materials in the parts provided to the kit purchaser; the FAA is now considering new rules which would bring wholesale change and potentially bar this degree of kit preparation by the manufacturer. "If the FAA succeeds in doing what they tell us they want to do, I think it would be very difficult for us to stay in business here in Central Oregon, or anywhere in the U.S.," said Joe Bartels, President of Lancair Company. "While we are certainly in the business of developing and selling high performance aircraft, and staying in the forefront of aviation technology, a key aspect of our business is the ability to provide the customer with all of the parts necessary to build a plane. To now say that I can't provide a section of carbon fiber wing as part of a kit, would really affect the entire industry," Bartels explained. Rick Schramek, CEO of Bend-based Epic Aircraft, praised the entry of U.S. Senator Ron Wyden into the issue in support of their industry. “Having Senator Wyden get into the game on our side with the FAA is the single best news we’ve had on this issue in some time. We have no doubt that other Oregon officials will also be there with us,” he said. Last week the FAA announced a moratorium on performing inspections on new experimental class aircraft, which includes kit airplanes assembled by their owners. Over the past two decades, experimental aircraft manufacturers and component suppliers have brought to the general aviation market the majority of new technology and safety improvements. Senator Wyden, a nationally-recognized friend of high technology companies, sees the FAA move as an attack on both innovation in the industry as well as job creation in a sector that pays above average wages. Epic Air, which has launched more models of new airplanes in a shorter period of time than any other company in history, met with FAA officials in Washington D.C. last week regarding the issue, but Schrameck credits Senator Wyden’s efforts for bringing the agency back to the table to discuss the change. “I’ve rarely seen a member of Congress act with such speed and conviction regarding an issue impacting an industry,” notes Schrameck, who also has 30 years of experience in the high technology industry. Oregon’s aerospace industry is comprised of more than 60 companies. Kit aircraft manufacturers and their suppliers employ more than 1,500 people. Kit manufacturers operating in the state include Lancair, Epic Air, Vans, BD Micro Technologies; Sport Copter, and Windward Performance. Philiben provides an example of incandescent lighting, which his company manufacturers. For the experimental market, the current testing and evaluation procedure for a new reflector would span one or two nights. The testing for the same reflector for the certified market would take a year to 18 months at a cost of tens of thousands of dollars to meet all the onerous regulatory requirements. Other areas of the world have lost or gained business, Philiben says, due to their respective regulatory environment for aircraft production. “The Brazilian firm Embraer has taken over globally the regional commercial aircraft market – a market that was the backbone of the British, Dutch, Swedish and German aviation airframe industry. This industry no longer exists in these countries. We need more champions for the general aviation industry, like Senator Wyden, who understand that seemingly small, incremental administrative changes undermine the viability for American firms to compete.” Economic development leaders in the Central Oregon region, where much of the state’s general aviation manufacturing industry is concentrated, also praised Wyden’s consistent efforts to support growth and innovation in the industry. “Senator Wyden has been remarkable in his ability to forcefully represent the interests of this sector in Washington,” said Lee of EDCO. “We are hopeful that other local, state and federal leaders will get educated on this issue. What we cannot understand -- and what has never been explained by FAA -- is who is being harmed by the current standard? The moratorium and proposed rule changes appear to be over FAA control rather than for safety reasons - the primary reason for agency’s oversight. Is a kit airplane assembled in an owner’s garage inherently safer than one assembled by the owner in a modern kit part factory? Some leaders in the industry speculate that the FAA wants to force all aircraft manufacturing to be certified. Certification costs for a small general aviation aircraft today can run from $200 million to $1.4 billion and typically require 2-5 years to complete. While FAA officials have said that they will reconsider the moratorium on new kit inspections, the battle over rules appears far from over. The immediate goal is to allow consideration of new amateur-built experimental aircraft models under the existing rules, and to get the FAA to the table on possible new criteria for calculating whether the majority of work in building an airplane was done by the individual purchaser, and not by the kit manufacturer, and what the net effect is regarding safety for the general public. “We think a workable solution can be found that enables the industry to grow and innovate better and safer aircraft, but we must get back to a constructive dialog,” concludes Schrameck. Industry leaders are lobbying for joint rule making that involves both FAA administrators and kit manufacturers. About Economic Development for Central Oregon Economic Development for Central Oregon (EDCO) is a private non-profit corporation founded 26 years ago and dedicated to building a vibrant and thriving regional economy by attracting new investment and traded-sector jobs (manufacturing, professional, headquarters and high technology businesses) through marketing, recruitment and substantive assistance to existing companies.

What if two or more precision-guided air-launched weapons such as bombs or missiles were able to share information in flight to adjust to changing targets, re-direct as needed or thwart enemy attempts to “jam” the electronic guidance systems of the weapons? Such a concept is no longer a future question regarding an undetermined time in future warfare … it is here. Last year, two Air Force F-16s fired Small Diameter Bombs which shared threat data with one another while in flight to a target using an emerging kind of collaborative weapons coordination, enabling the bombs to adjust trajectory and change course in response to identifying enemy guidance jamming signals. Rapid progress with this emerging program, called Golden Horde, is coming to fruition in part due to innovation, research and experimentation going on within the Air Force Research Lab. In an interview with Warrior, Air Force Research Lab Maj. Gen. Heather Pringle explained some of the technological progress which is driving this program. Certainly an ability to gather, analyze and share target specifics “in flight” in a collaborative way introduces new, paradigm-changing tactics into the realm of Air War.

According to the definition, Military training or air force is a branch of the armed forces that conducts most of its operations from the air. Unlike the army or navy, the air force is independent of the armed forces. Traditionally, the air force occupies the air space and performs both tactical and strategic duties. Aerial reconnaissance and close air support often use to support land and naval forces. As well as air forces that can embody several air components from different nations’ air forces, the term air force may also refer to an operational formation within an air force. Many aircraft types are involved in an air force: the more advanced the plane, the more human resources necessary to operate it. Several air defense assets are often controlled and commanded by air forces. The defense systems and networks use to detect and neutralize ballistic missiles. Work & Purposes Of Air Force Learn about the core functions of the air force. They perform a variety of essential roles like disaster relief and search and rescue and maintain their tactical and strategic capabilities. Maximizing Strategic Capability The Air Force must adapt to changing threats from inside and outside the country to maintain optimum capability. The following resources are available: the company operates high-tech, sophisticated aviation equipment. Moreover, engage the best and brightest in the country, use world-class intelligence and communication technologies, their employees are trained, educated, and rewarded for their maximum performance. Communication & Intelligence Services Keeping aircraft, deployed personnel, and command posts in touch with complex ICT systems is a mandatory Air Force requirement. Their sophisticated surveillance and intelligence collection systems include cable, radio, microwave, and satellite technology. Moreover, they are maintaining superiority in strategic thinking and identifying threat elements.Also, check about Military basic training Protecting Nation’s Interests Our nation, people, values, and way of life are all under the Air Force’s stewardship in cooperation with the Navy and Army. These are the methods they use: - Assuring the safety of the air, - Reconnaissance and surveillance are methods of acquiring intelligence. - All operational needs performed by air mobility - Providing strike capabilities in support of combat missions. Protecting, Rescuing & Responding To Disasters As part of its defense mission, the Air Force conducts overseas and domestic operations. These include: - Firstly, taking part in initiatives to combat terrorism and international security - Secondly, prevent illegal activities and incursions at our borders - Thirdly, the act of searching and rescuing - Also, maintaining peace in the country - Providing disaster relief to local communities Being Effective & Flexible From air forces’ tactical missions to their search and rescue and disaster relief missions, advanced Air Force technology provides the edge. High-tech logistic and intelligence resources help support our flexible aircraft and systems. Other than pilots, the air force consists of various personnel, and other personnel plays a vital role in their operations. Also, the armed forces require personnel ranging from logistics to intelligence to special operations, cyber support, and weapons loaders. As well as Air Force operations, some air forces also operate missiles and spacecraft. Air defense forces are usually separate from a nation’s air force, principally in countries that modeled their military after the Soviet Union.

A number of environmental organizations in Texas have sued the US Federal Aviation Administration over the testing of the Starship rocket. They believe that the launch permit is obtained illegally and demand that it be revoked. Meanwhile, Elon Musk said that he was ready to re-launch in 6-8 weeks. Eco-activists have filed a lawsuit On Monday, May 1, the environmental organization Center for Biological Diversity filed a lawsuit against the US Federal Aviation Administration (FAA). The reason was the test flight of the SpaceX Starship spacecraft, which took place on April 20. It ended with the detonation of a rocket at an altitude of several tens of kilometers and a large amount of debris falling to the ground. Representatives of the Center for Biological Diversity insist that the FAA cannot fully assess the damage that Starship launches are causing to the environment. This statement was supported by a number of other organizations, such as the American Bird Conservation Organization, Rio Grande Valley and a number of others. They insist that the five-year permit issued by the FAA to SpaceX should be revoked. “It’s vital that we protect life on Earth even as we look to the stars in this modern era of spaceflight,” said Jared Margolis of the Center for Biological Diversity. The FAA declined to comment, noting that it did not comment on the ongoing lawsuit. The agency is monitoring the accident investigation and has temporarily banned Starship launches until SpaceX proves their safety to citizens. Elon Musk is ready for new Starship Launches Meanwhile, the owner of SpaceX, Elon Musk, said on Sunday that he was ready to re-launch Starship in 6-8 weeks. The rocket explosion did not cause any significant damage to citizens, since the launch pad is located 20 km from the nearest settlement. However, the debris damaged at least one private car in the published photos. At the same time, the company recognizes that the launch of Starship really has entailed a number of unpredictable consequences. In particular, a crater formed at the launch site, and the launch pad was seriously damaged. Pieces of steel and concrete, torn from it, rose high into the sky. The dust formed a plume that stretched for 6 km. Musk said that changes had been made to the affected structures that would prevent a repeat of this situation. Right now, work is underway at the cosmodrome to strengthen them. In addition, the rocket detonation system will be improved so that in case of an emergency situation it can be destroyed immediately, and not 40 seconds after the need arose.

Malaysia's acting transport minister has said that reports that the missing Malaysian airplane flew for a number of hours are "inaccurate". Hishammuddin Hussein's comments come after the Wall Street Journal reported that US investigators suspect the aircraft flew for about four hours after reaching its last confirmed location. Speaking at a press conference in Kuala Lumpar, Mr Hussein also said satellite images released are not plane debris in the South China Sea. Mr Hussein said that China had told Malaysia the satellite photos were released "by mistake and did not show any debris". Meanwhile, China has put pressure on Malaysia to improve its coordination over the search for the Boeing 777, which disappeared early on Saturday on a flight from Kuala Lumpur to Beijing. Of the 239 people on board, up to 154 were Chinese. Premier Li Keqiang demanded that the "relevant party" step up coordination, while China's civil aviation chief said he wanted a "smoother" flow of information from Malaysia. Malaysia authorities have come under heavy criticism for their handling of the disaster. Vietnamese and Malaysian planes scanned waters where a Chinese government agency website said a satellite had photographed three "suspicious floating objects" on Sunday. The location was close to where the plane, Flight MH370, lost contact with air traffic control. Aircraft repeatedly circled the area over the South China Sea but were unable to detect any objects, said a Reuters journalist, who was on board one of the planes. It was the latest in a series of false signals given to the multi-national team that has been searching 27,000 square nautical miles (93,000 square km), an area the size of Hungary, for the Boeing 777-200ER. Yesterday, Malaysia's air force chief said military radar had traced what could have been the jetliner to an area south of the Thai holiday island of Phuket, hundreds of miles to the west of its last known position. His statement followed a series of conflicting accounts of the flight path of the plane, which left authorities uncertain even which sea to search in for Flight MH370. The last definitive sighting on civilian radar screens came shortly before 1.30am on Saturday, less than an hour after the plane took off from Kuala Lumpur, as it flew northeast across the mouth of the Gulf of Thailand. What happened next remains a mystery and the differing accounts put out by various Malaysian officials have drawn criticism of their handling of the crisis. Malaysia Air Force chief Rodzali Daud told a news conference yesterday that an aircraft was plotted on military radar at 2.15 am, 320km northwest of Penang Island off Malaysia's west coast at the northern tip of the Strait of Malacca. But there has been no confirmation that the unidentified plane was Flight MH370, he said. Malaysia was sharing the data with international civilian and military authorities, including those from the United States. "We are corroborating this," he added. "We are still working with the experts." According to the data cited by the air force chief, if the radar had spotted the missing plane, the aircraft would have flown for 45 minutes and dropped only about 1,500 metres in altitude since its sighting on civilian radar in the Gulf of Thailand. There was no word on which direction it was then headed, but if this sighting was correct, the plane would have turned sharply west from its original course, travelling hundreds of miles over the Malay Peninsula from the Gulf of Thailand to the Andaman Sea. This would put it about 320km northwest of Penang, in the northern part of the Strait of Malacca, roughly south of Phuket and east of the tip of Indonesia's Aceh province and India's Nicobar island chain. Indonesia and Thailand have said their militaries detected no sign of any unusual aircraft in their airspace. Malaysia has asked India for help in tracing the aircraft and New Delhi's coastguard planes have joined the search.

With the absorption of ANF-Mureaux in 1937 as a component of the SNCA du Nord (which also included Potez and retained the appellation for its products), Andre Brunet and his co-designers Lemaitre and Hubert continued the line of lightweight fighter development commenced with the ANF-Mureaux 190. In the autumn of 1938, work on a progressive development, the Potez 230, was begun. While possessing a number of features in common with the earlier fighter (eg, elliptical wings), the new aircraft was of more advanced design. Powered by a 670hp Hispano-Suiza 12Xcrs 12-cylinder liquid-cooled engine and having a proposed armament of one engine-mounted 20mm cannon and four wing-mounted 7.5mm machine guns, the Potez 230 was flown on 30 March 1940. When German forces occupied Villacoublay, the sole prototype of the Potez 230 was seized and transported to Germany for examination of the wing torsion box, which, of integral construction, was the first of its type to have been flown. |A three-view drawing (1280 x 954)| | Take-off weight||1800 kg||3968 lb| | Wingspan||8.74 m||29 ft 8 in| | Length||7.57 m||25 ft 10 in| | Height||2.18 m||7 ft 2 in| | Wing area||10.97 m2||118.08 sq ft| | Max. speed||560 km/h||348 mph| |paul scott, 08.09.2009| Similar outlook to the other French fighter, the Dewoitine.

Welcome to This Date in Aviation History, getting of you caught up on milestones, important historical events and people in aviation from October 6 through October 9. October 6, 1977 – The first flight of the Mikoyan Gurevich MiG-29. During the Vietnam War, the US Air Force discovered that using high speed fighter aircraft in the ground attack role left them vulnerable to attack from above. Air superiority became the watchword, as the US sought to hold control of the airspace over the battlefield in the same way they had late in WWII, and again during the Korean War. In the 1960s, the Air Force began its F-X program to develop a new air superiority fighter, a competition which brought about the superb McDonnell Douglas F-15 Eagle, which was awarded a production contract in 1969 based on a technical proposal and took its maiden flight in July 1972. But the arms race being what it was, and still is, the Soviet Union had to respond to the threat posed by this new high-performance American fighter, and they began their own program in 1969 to produce a new frontline air superiority fighter to counter the Eagle. Dubbed Perspektivnyy Frontovoy Istrebitel (PFI, or Advanced Frontline Fighter), the program called for an agile, long-range fighter with Mach 2+ speed and the ability to operate from rough or unimproved airstrips. But as development progressed, the Russians found themselves in a similar situation as the Americans, needing both a heavy air superiority fighter and a lighter multi-role fighter. Thus, the MiG-29 became roughly analogous to the General Dynamics F-16, while the larger and heavier Sukhoi Su-27 took on the role of the heavy fighter. The MiG-29 is powered by a pair of Klimov RD-33 afterburning turbofans spaced far enough apart that the area between them produces additional lift. Air intake flaps are fitted that prevent the ingestion of foreign object debris during landing and takeoff from unpaved airstrips. The MiG-29 is armed with a single 30mm cannon in the wing root, and is also fitted with a laser rangefinder and infra-red search and track (IRST) system housed in an eyeball-like bubble forward of the cockpit. This system allows the pilot to track targets that emit infrared radiation while not giving off any energy of its own, making it difficult for the target aircraft to know they are being tracked. Numerous missiles, rockets, and bombs can also be fitted to its six underwing hard points. The MiG-29 entered service with the Soviet frontline forces in 1982 and was given the NATO designation Fulcrum. By the mid-1980s, the MiG-29 began appearing at international air shows, but the capabilities of the Fulcrum remained a mystery to the West until analysts and pilots were able to fly a number of them following the reunification of Germany in 1990. In 1997, the US bought Moldova’s stock of 21 MiG-29s to prevent their sale to Iran or other rogue states, and the purchase had the added benefit of providing an opportunity to train head to head against the Fulcrum. Western analysts found the Fulcrum to be a capable dogfighter, notable for its helmet-mounted sight that could target an air-to-air missile while the aircraft’s nose was pointed in another direction. But it also had a relatively short range and a somewhat primitive cockpit that limited the pilot’s situational awareness of the battle space. Like most Russian warplanes, the Fulcrum has been continuously updated throughout its service life and exists in a myriad of variants, including two-seat training variants, an export version, a carrier-capable variant, as well as a substantially modernized MiG-35 variant. Over 1,600 aircraft have been produced, and the MiG-29 continues to serve the air forces of 26 nations. October 7, 1934 – The first flight of the Tupolev ANT-40 / SB. Prior to the start of WWII, the design of bomber aircraft began to separate into two general trends. The first was large, heavy bombers capable of flying long distances with large bomb loads. These bombers packed a punch, but they weren’t particularly fast, and were vulnerable to interception by enemy fighters. The second was the development of medium-sized, twin-engine bombers that carried fewer bombs but used their higher speeds as protection from enemy fighters. In 1933, the Soviet Air Force ministry issued a requirement for a new high speed bomber designated Skorostnoi Bombardirovschik (SB) and work on the new aircraft began at the Tupolev design bureau at the Central Aerodynamic Institute (TsAGI). Beginning in the early 1930s, aircraft designers moved away from fabric-covered wooden frameworks to stressed skin aircraft, an arrangement where the aircraft’s metal skin helps to keep the aircraft’s box frame rigid. Tupolev’s prototype bomber, known as the ANT-40, was the first modern stressed skin aircraft produced by the Russians in large numbers, and was initially created two versions. The first, known as the ANT-40RT, was powered by a pair of Wright R-1820 Cyclone engines and was the first to fly. The second, known as the ANT-40IS, was powered by two Spanish-made Hispano-Suiza 12Y liquid cooled V-12 engines. The bomber had a crew of three and a top speed of 280 mph, could carry up to 2,200 pounds of bombs, and was armed with four defensive machine guns. The ANT-40IS served as the production prototype for the Skorostnoi Bombardirovschik, but the first SBs started rolling off the production line before the testing program had even completed. As a result, the assembly lines faced numerous difficulties because of constant modifications to the production process. Many pilots and maintenance personnel were upset with the early shortcomings of the SB and, when the Russian Commissar for Heavy Industry, Sergo Ordzhonikidze, came for an inspection, the crews covered their aircraft with placards complaining about the problems. Andrei Tupolev was summoned for an audience with Soviet leader Joseph Stalin, where he told the Russian leader that most of the defects were trivial. Stalin replied, “There are no trivialities in aviation; everything is serious and any uncorrected triviality could lead to the loss of an aircraft and its crew.” As production of the SB continued, refinements and improvements slowly made their way into the fleet, and the SB first saw action with the Spanish Republicans during the Spanish Civil War in 1936. There, the SB proved to be faster than contemporary fighters, and significantly faster than the older biplane fighters it faced. The SB also saw service in China, Mongolia, Finland, and some captured aircraft were flown against the Russians by the German Luftwaffe and Finnish Air Force. Despite its speed, the rapid pace of fighter development rendered the SB obsolete by 1941, and the remaining aircraft were used as transports and cargo aircraft. A total of 6,656 SBs were produced between 1936 and 1941, making it one of the most numerous aircraft of its day. October 7, 1932 – The first flight of the Stipa-Caproni. The decades of the 1920s-1930s are known as the Golden Age of Flight, an era marked by an explosion in the popularity of flying as well as rapid technological advancement. While many designers worked to refine more traditional aircraft, others took the opportunity to experiment with radical aircraft of entirely new design. Some of those innovative aircraft were developed into successful production designs, while others, though ultimately unsuccessful, paved the way for aircraft of the future. One of the more exotic ideas to come out of this period was the Stipa-Caproni, also known by the reverse name Caproni Stipa. Created by Italian engineer Luigi Stipa and built by manufacturer Caproni, the barrel-like fuselage was a tapered airfoil shape which created a venturi that compressed the air moved by the propeller and sped it up, putting into practice the principles of fluid dynamics first described by Daniel Bernoulli in 1738. Stipa called his invention an intubed propeller, and he rigorously calculated the shape of both the tube and the propeller, as well as the speed of the propeller, for optimal efficiency. The aircraft’s elliptical wing passed through the oversized fuselage behind the propeller, and the rudder and elevators were mounted directly behind the tubular fuselage to benefit from the passage of air through the fuselage. Two pilots sat in tandem high atop the aircraft. In 1932, Stipa convinced the Italian government to fund the construction of his unorthodox airplane. Test pilots found that the aircraft was extremely stable, almost to the point of being difficult to turn. And the fact that the entire aircraft helped generate lift meant that extremely slow landing speeds were possible. Despite promising test results, the Stipa-Caproni failed to outperform contemporary aircraft, and the project was canceled. However, Stipa’s work was quite influential and widely studied, and some consider his intubed propeller, which is essentially a ducted fan, as the precursor to the modern turbofan engine. October 9, 1999 – The final flight of the Lockheed SR-71 Blackbird. Before the advent of reliable reconnaissance satellites, it was up to aircraft to perform the often dangerous job of spying on the enemy. But postwar reconnaissance aircraft, often not the fastest aircraft available, were vulnerable to fighters, and a number of American spy planes were shot down as they probed the borders of the Soviet Union. The high-flying Lockheed U-2, which could reach altitudes beyond the reach of fighters, removed much of the danger, but it remained vulnerable to anti-aircraft missiles. In 1957, Lockheed began investigating an aircraft that could take over the job of spying on the Soviet Union from the vulnerable U-2. This task became more urgent in 1960 when a U-2 flown by Francis Gary Powers was shot down by a surface-to-air missile over the Soviet Union while photographing nuclear missile sites. Lockheed’s goal was to create a plane that was untouchable by any fighter or missile in existence. In addition to making a plane that flew still higher and faster, Lockheed also experimented with technologies that reduced the aircraft’s radar signature and was the precursor to what we know as stealth technology today. The result of Lockheed’s work led to the single-seat Lockheed A-12, which first flew in 1962. The A-12 was followed by the SR-71 Blackbird, and though it was not as fast as the lighter A-12, its increased range and more advanced sensors made the Blackbird a more capable aircraft. The SR-71 also added a second crewmember to handle the reconnaissance work, allowing the pilot to concentrate on flying the plane. Powered by two Pratt & Whitney J58-1 continuous bleed afterburning turbojets, the Blackbird was capable of speeds up to Mach 3.3 at 80,000 feet. It could not be shot down by the surface-to-air missiles of the day, and it was faster than any contemporary Soviet fighter. The Blackbird took its maiden flight on December 22, 1964 and entered service in 1968. Blackbirds based in Okinawa were soon flying as many as two missions a week over enemy territory, most often North Vietnam and Laos. Flying from European bases, Blackbirds probed the edges of the Soviet Union and provided intelligence during US military operations in Libya. But along with the unsurpassed capabilities of the SR-71 came very high operating costs, and it became a political issue in an era of shrinking budgets and competition for funds. In 1989, the Blackbird was retired from service, even at a time of escalating tensions in the Middle East when it could have performed valuable reconnaissance in the upcoming Gulf War. When the US government realized that it still had a need for the high-flying spy plane, the SR-71 was updated with real-time data transmission capabilities and reactivated in 1993, despite stiff opposition from the US Air Force who said they didn’t have the funds to operate it. The Air Force also claimed that the Blackbird competed for funds with unmanned reconnaissance projects currently under development. After another political battle over funding the aircraft, the SR-71 was permanently retired in 1998, and the last two airworthy Blackbirds were transferred to NASA for research. The book on the Blackbird was finally closed on October 9, 1999 when the last flying aircraft, an SR-71A (61-7980/NASA 844), landed at Edwards AFB in California and was placed in storage with the other NASA Blackbird. As of its official retirement, the Blackbird had logged 53,490 flight hours with only one pilot lost to an accident. None were lost to enemy fire. All remaining aircraft (as far we know) are now housed at aviation museums around the country. October 6, 1983 – The first flight of the Bell OH-58D Kiowa Warrior. The OH-58 Kiowa, a development of the Bell Model 206 JetRanger, entered service in 1969 in response to an Army requirement for a light observation helicopter (LOH). The OH-58D Kiowa Warrior variant was a product of the Advanced Helicopter Improvement Program (AHIP) which included improved radar for nap-of-the-earth flight, a quieter four-bladed rotor, and a mast-mounted sight (MMS) for locating targets from behind the cover of terrain. The OH-58D is fitted with pylons that can hold two Hellfire missiles, seven rockets, two air-to-air Stinger missiles or one fixed .50 caliber machine gun. October 6, 1954 – The first flight of the Fairey Delta 2, a British research aircraft that was developed to explore the regimes of transonic and supersonic flight. The Fairey Delta 2 was powered by a single Rolls-Royce Avon 200 axial flow jet engine and was the first aircraft to exceed 1,000 mph, a world speed record that it held for more than a year before being surpassed by the McDonnell F-101 Voodoo. The Delta 2 was also the first British aircraft to have all of its flight surfaces hydraulically controlled. Two prototypes were built, and one was significantly modified to become the BAC 221 which was used for high-speed delta wing testing in the development of the Concorde supersonic transport. October 6, 1939 – The first flight of the Curtiss SO3C Seamew, a monoplane seaplane designed for the US Navy to replace the SOC Seagull. Per the US Navy requirement, the Seamew could be equipped with either a float or landing gear. To address stability problems, the wingtips were curved upward, and the vertical stabilizer extended across the observer’s cockpit. Due to unresolved problems with the Ranger V-770 inline V-12 engine, the Seamew was withdrawn from frontline units in 1944 in favor of the older biplanes it was meant to replace. Nearly 800 were built, and it was retired in 1945. October 7, 1995 – The first flight of the Mitsubishi F-2, a fighter built in cooperation between Lockheed Martin and Mitsubishi Heavy Industries. Based on the General Dynamics F-16A Fighting Falcon, the F-2 features a larger wing made of composite materials, larger tail plane, larger nose housing a more a powerful radar, a larger air intake and a three-piece canopy. Under the terms of the partnership, advances made in the F-2 were transferred back to Lockheed Martin for use in future US fighters. Produced from 1995-2011, 94 aircraft have been built and serve with the Japan Air Self-Defense Force. October 7, 1963 – The first flight of the Learjet 23, the world’s first light business jet. A true pioneer in the world of business jet (bizjet) aviation, the LearJet 23 originated in Switzerland where it was conceived by William Lear and designed by Hans-Luzius Studer, who had worked previously on the FFA P-16 fighter for Switzerland. The six-passenger bizjet became an instant success, and production was moved to the US where 105 aircraft were produced from 1962-1966. The LearJet has been continuously upgraded and enlarged since, and newer variants remain in production. October 9, 2009 – The Centaur module of NASA’s Lunar Crater Observation and Sensing Satellite (LCROSS) crashes on the Moon. In an effort to determine whether or not the polar regions of the Moon contain subsurface frozen water, NASA launched LCROSS along wth the Lunar Reconnaissance Orbiter on June 8, 2009 atop an Atlas V rocket. LCROSS consisted of a Shepherding Spacecraft that was attached to the spent Centaur upper stage of the Atlas rocket. Once over the southern pole of the moon, the rocket stage was launched into a shaded crater and followed down to the surface by the Shepherding Spacecraft with its sensors. The Atlas stage impacted the crater at approximately 5,600 mph and, while the debris plume was not as large as scientists hoped for, the trailing spacecraft was still able to confirm the presence of water on the Moon. October 9, 1987 – The first flight of the AgustaWestland AW101, a joint venture of the Italian company Augusta and the British company Westland to produce a medium-lift naval helicopter. Known by Britain, Denmark, Norway and Portugal as the Merlin, the AW101 is powered by three Rolls-Royce Turbomeca turboshaft engines and entered service in 1999 in the transport, anti-submarine warfare (ASW) and ship-based utility roles. It now serves with both military and civilian operators of 11 nations. In 1999, the US Navy and Marine Corps initiated the VXX program to find a replacement for the Sikorsky VH-3 Sea King used to transport the US president, and the AW101, designated the Lockheed Martin VH-71 Kestrel, was considered in the competition before being canceled in 2009 after significant cost overruns.

The strongest solar radiation storm since 2005 is still in progress, and Americans in northern states can expect to see the effects on Tuesday night. The solar eruption occurred at about 11 p.m. Sunday and has hit the Earth with three different effects at three different times. The radiation first arrived an hour after the flare, and is set to continue through Wednesday. The radiation risk could case satellite disruption and electrical grid outages, according to the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center in Colorado. Passengers on flights traveling at a high altitude are at a higher than normal radiation risk. The first effect from the flare is electromagnetic radiation, followed by radiation in the form of protons. The actual plasma from the sun, called the coronal mass ejection, hit at around 9 a.m. Tuesday. The CME is likely to reach G2 (Moderate) levels, with a possibility of G3 (Strong) storms. NASA’s flight surgeons and solar experts have determined that the six astronauts currently on the International Space Station are not at risk. The plasma is what causes most of the power outages on Earth, and pulls the Northern Lights further south. On Monday night residents in Scotland, northern England, Canada and northern parts of Ireland were treated to aurora borealis. Parts of New England, upstate New York, northern Michigan, Montana and the Pacific Northwest could also see the rare light show on Tuesday evening. With Associated Press

The importance of vibration testing in qualifying and accepting spaceflight hardware cannot be overstated, but the testing also introduces significant programmatic risk. Join us for the next Virtual PM Challenge on May 1, 2019. Joe Gasbarre, NASA Science Mission Directorate Chief Engineer, discusses the engineering side of science missions. Seven selected for Project Mercury went on to blaze bold paths in space exploration. Reflecting and learning from an accident can be an emotionally painful process, but also extremely important to improving safety in the future. The failure of a high pressure industrial water valve actuator assembly at a NASA test stand underscored the need for disciplined configuration control practices to ensure facility systems are built and maintained to the specified design. Crucial, complex safety system will rocket astronauts to safety at the first sign of danger.

TanDEM-X (TerraSAR-X add-on for Digital Elevation Measurement) opens a new era in space borne radar remote sensing. The first bistatic SAR mission, is formed by adding a second, almost identical spacecraft, to TerraSAR-X and flying the two satellites in a closely controlled formation with typical distances between 250 and 500 m. Primary mission objective is the generation of a consistent global digital elevation model with an unprecedented accuracy according to the HRTI-3 specifications. Beyond that, TanDEM-X provides a highly reconfigurable platform for the demonstration of new SAR techniques and applications. The mission has been approved for full implementation by the German Space Agency and TanDEM-X is launched on June 21, 2010. The TDX satellite is as much as possible a re-build of TSX with only minor modifications like an additional cold gas propulsion system for constellation fine tuning and an additional S-band receiver to enable a reception of status and GPS position information broadcast by TSX. This guarantees a low development risk and it offers the possibility for a flexible share of operational functions for both the TerraSAR-X and TanDEM-X missions among the two satellites. The TDX satellite is designed for a nominal lifetime of 5 years and has a nominal overlap with TSX of 3 years. TSX holds consumables and resources for up to seven years of operation, allowing for a potential prolongation of the overlap and the TanDEM-X mission duration. The scientific use of the data can be divided into 3 areas: new quality Digital Elevation Models (e.g. for hydrology), along-track interferometry (e.g. measurement of ocean currents) and new bi-static applications (e.g. polarimetric SAR interferometry). The potential for commercial applications arises from the increase in the efficiency of the TerraSAR-X data production chain, high quality and efficient cartographic capability, as well as implementation of experimental modes and services. TanDEM-X represents the first step for a constellation of radar satellites and will ensure the German leading position for X-Band SAR technology. The user community has access to a broad spectrum of scientific, commercial and security applications.

The imagination of flying was restricted to the avifauna and the hereafter. An oriental concept of flying was for example presented by Pier Paolo Pasolini in an episode of his trilogy of myths using a flying horse. Though such couldn’t induce any practical conclusions in the occident. Still in 1880, the gifted Alphonse Pénaud was mocked and his problem solving of the aviation thrust through the invention of the rubber engine misunderstood. It was the media coverage of Otto Lilienthal’s flight experiments through scientific photo documents that first made the concept of overcoming gravity comprehensible to a broader public. Lilienthal’s success isn’t conceivable without the photographical pioneer Ottomar Anschuetz. Flying without means of imagination is unthinkable. Flying is nothing but a repeatable realization of flight relativity. Flying is an intellectual overcoming of gravity. estación experimental de dinámica de fluidos barcelona 41°24’31 N 2°11’59 E investigación de la gravedad aero

In 1932, the German military began funding von Braun's work, and after heading a team of 80 engineers building rockets in Kummersdorf, he took over a new, custom-designed facility at Peenemunde in the Baltic, the remoteness of which allowed long-range rocket testing. By 1943, von Braun's team had successfully developed several rockets—the A-2, A-3, and A-4, the last capable of reaching Britain. Von Braun made no secret of his interest in sending rockets to explore space rather than using them as weapons, leading the German Schutstaffel (SS) and Gestapo to arrest him for frivolous indulgence. In 1943, as an Allied victory seemed increasingly likely, Adolf Hitler ordered von Braun's group to develop the A-4 as a "weapon of vengeance" to shower explosives on London. Von Braun's colleagues argued that, without him, they could not accomplish this task, so he was freed. The first operational V-2 ("Vengeance") rocket was launched in September 1944. In early 1945, fearing for his group members' personal safety and the program's future, von Braun stole a train, forged travel documents, and led his production team to surrender to U.S. military representatives in western Germany. The Americans seized V-2s, spare parts, and scientific documents from the Peenemunde and Nordhausen facilities and gave von Braun and 126 of his scientists visas for the United States. The group initially settled at Fort Bliss, Texas, but transferred to Huntsville, Alabama, in 1950, where they shared their knowledge with American scientists and laid the foundations of the U.S. rocketry and space-exploration programs. Von Braun's well-publicized suggestions that the United States build a space station and launch manned missions to the moon contributed to the establishment of the National Aeronautics and Space Administration in 1958, Skylab, and the Apollo space program during the 1960s. Von Braun retired in 1972, and he died at Alexandria, Virginia, on 16 June 1977. Bergaust, Erik.

Argentina’s new presidential aircraft, a Boeing 757, was spotted with its new livery at Dallas Love Field Airport (DAL) in Texas, the United States. The aircraft, a Boeing 757 registered as ARG-01, was seen arriving at DAL from Salina Regional Airport (SLN), a regional airport in Kansas where, according to planespotters.net data, it was stored between March 31 and May 17, 2023. According to ch-aviation.com data, the Rolls-Royce RB211-powered Boeing 757 was initially delivered to Iberia in April 2000 and was used by the airline until 2005. Between 2005 and 2022, Fun Air, a manufacturer of inflatable water toys for superyachts, owned the aircraft, which was registered as N757AG. The company now owns a Boeing Business Jet (BBJ) 737, registered as N737AG. C&L Aerospace helped the government of Argentina to acquire the VIP-configured Boeing 757 in exchange for the country’s older presidential 757. According to a statement issued by the company on April 13, 2023, it completed the sale of the new aircraft to “the Secretary General of the Presidency of Argentina for the purpose of presidential travel” by taking the existing presidential Boeing 757 “as a trade”. According to C&L Aerospace, the new aircraft can seat up to 39 passengers, and features a bedroom and two other rooms. “We were happy to assist one of our principal customers in acquiring this critical asset for their government,” said Martin Cooper, the Senior Vice President of Sales at C&L Aerospace. “The nature of our business and the emphasis we put on the relationships we have with our customers lends itself well to helping solve their complex problems and support needs.” The previous presidential 757, registered as T-01, was delivered new to Fuerza Aérea Argentina (the Argentine Air Force) with a pair of Rolls-Royce RB211 engines in July 1992. C&L Aerospace is now selling the “low-time” 757 in an as-is condition.

Algerian Yak-130 pilots go solo Written by defenceWeb, Monday, 12 September 2011 Algerian pilots performed their first solo flights on the Yak-130 at Irkutsk Aviation Plant’s airfield on the first of this month. They first underwent a three month course covering flight theory and practical training, according to Irkut. Algerian pilots along with the Irkut’s flight crew made more than 100 flights on the Yak-130 before going solo. In addition to pilots, a large number of Algerian engineers and technicians are attending the Yak-130 training course provided by Irkut. In 2006 Irkut Corporation signed a contract for 16 Yak-130s for the Algerian Air Force. According to the ITAR-TASS news agency, the Irkutsk Aviation Plant will start delivering Algeria’s aircraft before the end of the year. “About 30 fighters have already been assembled and are at the final stage of readiness,” said Irkut Aircraft Corporation President Alexei Fyodorov. Algeria bought the Yak-130s as part of an arms package worth US$7.5 billion during the visit of Russian President Vladimir Putin to Algeria in March 2006. The deal included the purchase of 28 Sukhoi Su-30MKA and 34 MiG-29 multirole fighters (28 single-seat MiG-29SMTs and six two-seat MiG-29UBTs) as well as eight batteries of S-300PMU-2 air-defence missile systems and 24 Almaz-Antei 2S6M Tunguska 30 mm/SA-19 self-propelled air-defence systems. Deliveries of the MiG-29s was suspended and the 15 aircraft that had arrived returned to Russia following quality problems, but the Su-30s were accepted without issue. The Yak-130 was designed to provide basic and advanced pilot training for Russian and foreign-made combat aircraft, including 4th+ and 5th generation fighters. The aircraft is fitted with an advanced glass cockpit and can carry 3 000 kg of weaponry. The Yak-130 was chosen as the main aircraft for basic and advanced training of Russian Air Force pilots. Deliveries to the Russian Air Force, which expects to order an initial 72 aircraft, began in February last year. Libya was the second export customer for the Yak-130 and ordered six. However, following the civil war there, deliveries have been frozen. “We do not know what will happen to it,” Fyodorov said about the Libyan contract. “But in any case, the planes that have been made for this country will be reoriented for another customer, first of all – for the Russian Air Force.” Irkut estimates the market capacity for the Yak-130 is 250 aircraft between now and 2015.

Review: Footprints in the Dust by Jeff Foust Monday, September 20, 2010 Footprints in the Dust: The Epic Voyages of Apollo, 1969–1975 by Colin Burgess (ed.) Univ. of Nebraska Press, 2010 hardcover, 520 pp., illus. “Considering one irrefutable fact—that there have been literally dozens of books written about the Apollo program—it took a mighty effort to come up with new angles and fresh material in approaching this well-known and certainly well-chronicled human endeavor,” Colin Burgess writes at the beginning of Footprints in the Dust. He is certainly right about the volume of works about the Apollo program: there is no shortage of general histories of the program, and over time most of the key players have been profiled in biographies or written their own memoirs. This has resulted in an increasing specialization of books about the era, including recent ones about the television cameras used on the Apollo missions (see “Review: Live TV From the Moon”, The Space Review, June 21, 2010) and the role of a little-known Australian tracking station (see “Review: Carnarvon and Apollo”, The Space Review, July 19, 2010). So what are the “new angles and fresh material” that Burgess provides in Footprints in the Dust? The book is a collection of essays by what Burgess describes as “a cadre of spaceflight enthusiasts” that traces the history of human spaceflight from Apollo 11 through the end of Apollo, the Apollo-Soyuz Test Project (ASTP) in 1975. (Despite the subtitle, the book covers both the Apollo program and Soviet efforts during the same period.) Each mission from Apollo 11 through 17 gets its own chapter; Skylab is condensed into a single chapter, as is ASTP, while several essays examine the Soviet programs, including their failed lunar mission efforts, early Salyut space stations, and the Soyuz 11 accident. |The book is a collection of essays by what Burgess describes as “a cadre of spaceflight enthusiasts” that traces the history of human spaceflight from Apollo 11 through the Apollo-Soyuz Test Project in 1975.| The result is, in many cases, a rather conventional history of Apollo. The essays on most of the Apollo missions, particularly 12 and 14 through 17, are all fairly standard histories, with background about the astronauts and an account of the key events of the mission. The book wisely departs from this formula for the two best-known Apollo missions: Stephen Cass examines Apollo 13 from the vantage point of the flight controllers who worked to bring the wounded spacecraft home safely, while Rick Houston dispenses with a general review of Apollo 11 altogether, focusing more on how various people watched and remembered the mission, from a young boy who would later become an astronaut (Tom Jones) to a Vietnam POW who only indirectly found out about the landing weeks later. Similarly, the essay about ASTP is as much author Geoffrey Bowman’s tale of his journey from the UK to Florida to see the launch as it is about the mission itself. Beyond that, there isn’t much in the way of new material in the book, although the essays about the Soviet program of that era are likely to be more enlightening than the Apollo essays simply because the typical reader is probably less familiar with the details about Soviet missions. That doesn’t mean that Footprints in the Dust is a bad book: it is, in fact, a good, general history of human spaceflight of that era. However, for those with more than a passing familiarity with those missions, the book won’t add much in the way of new insights about those missions or their broader historical context. It’s proof of Burgess’s statement in the introduction of just how well-chronicled this era in spaceflight truly is. Jeff Foust ([email protected]) is the editor and publisher of The Space Review.

IIC: Hawker Chief Designer Sydney Camm’s Hurricane ranks with the most important aircraft designs in military aviation history. Created in the late 1930s, when monoplanes have been regarded as unstable and too radical to be profitable, the Hurricane was the initial British monoplane fighter and the 1st British fighter to exceed 483 kilometers (300 miles) per hour in level flight. Hurricane pilots fought the Luftwaffe and helped win the Battle of Britain in the summer season of 1940. This Mark IIC was built at the Langley factory, near what is now Heathrow Airport, early in 1944. It served as a training aircraft during the World War II in the Royal Air Force’s 41 OTU.

The prototype 1st flew in 1942. P-61 combat operations started just soon after D-Day, June six, 1944, when Black Widows flew deep into German airspace, bombing and strafing trains and road visitors. Operations in the Pacific started at about the exact same time. By the finish of World War II, Black Widows had observed combat in every single theater and had destroyed 127 enemy aircraft and 18 German V-1 buzz bombs. The Museum’s Black Widow, a P-61C-1-NO, was delivered to the Army Air Forces in July 1945. It participated in cold-climate tests, higher-altitude drop tests, and in the National Thunderstorm Project, for which the prime turret was removed to make room for thunderstorm monitoring gear.

As a member of a VA, i fly many legs a day. Would be a nice option to have a flight time clock that can be reset after each leg. Totally agree. I also often do multiple sectors, and this would be so helpful! At the minute I have to use the stopwatch on my phone. Would be nice if we had to actually start and stop the clock too. You can see the flight time in the replay or change on e of the things in the status bar Not if it is per leg. It only logs total flight time There already one it’s called ETE to next Same. Basically would be a somewhat easy item to add Do you mean you do legs all in one flights? If so you can change the status bar to flight time and note it every time you land at a airport No not the same ETE TO NEXT is the estimated time elapsed until your next waypoint on your flight plan. This is requested a timer to log how long you have been flying per leg. It does not reset. So like today i am flying a a five leg flight. The flight time clock can not be reset unless i end each flight Everytime you land, note the flight time. Then minus then minus the time from your previous landing and then you have your flight time Or as every IRL aircraft has a flight clock for this reason. That’s inefficient and a hassle for large flights where you’re doing over 5 legs in a row. Having it implemented in game would be a lot better and simpler for the hoppers out there. Exactly thank you

New crew boards International Space Station (Roundup) Oct 10, 2010, 10:44 GMT Moscow/Washington - Two Russian cosmonauts and one US astronaut arrived early Sunday at the orbiting International Space Station aboard the Soyuz spacecraft, bringing the ISS back up to its targeted crew strength of six. The US space agency NASA said the docking was complete by 0309 GMT Sunday, when the hatch doors opened three hours after the craft arrived. The capsule blasted off Wednesday from the Baikonur Cosmodrome in Kazakhstan. Russians Alexander Kaleri and Oleg Skripotschka and American Scott Kelly are due to spend five months conducting more than 40 experiments in the space station. A number of spacewalks are also planned. They join the ISS crew of commander Doug Wheelock and fellow- American Shannon Walker, along with Russian cosmonaut Fjodor Yurtchichin. Moscow media reports said the three were especially pleased by the delivery of fresh fruit which the new arrivals brought with them, along with letters from friends and relatives. The Soyuz capsule flew for the first time with digital navigation technology. Soyuz will take over all astronaut transport in 2011, when the US retires its shuttle programme. The digital equipment replaces a nearly 30-year-old computer system on the Soyuz, at the same time making the capsule 70 kilograms lighter, weight which can now be taken up by more cargo. In Baikonur meanwhile, the Russian space holding company Energia assured that the next Soyuz launch would take place on schedule in December despite a glitch last week when the Soyuz capsule was damaged while being brought to the launching pad. 'It will take off in December,' Energia boss Vitali Lopota said. Read more about Russia Space Read more about US

Hubble Space Telescope NASAs Hubble Space Telescope is one of the most amazing scientific instruments that captures pictures of our universe the human eye would never see. NASA's Hubble Space Telescope has given us the most spectacular look at the universe. The Hubble telescope has captured many events including a colliding galaxy called "Tadpole." Another picture is a stunning collision between two spiral galaxies called "The Mice." NASA's Hubble Space Telescope has been around since 1990 and is one of the most amazing pieces of scientific equipment in orbit. Here's a look at how Hubble Space Telescope works. Hubble isn't on NASA's balcony. It's actually "flown" like a spacecraft. Think of a robot or computer in space that only responds to specific instructions from people on the ground. Hubble has communications antennae so astronomers and technicians can tell the telescope what to do and when to do it. Four antennae send and receive info between the telescope and the Flight Operations Team at the Space Telescope Science Institute. In order for NASA's Hubble Space Telescope to work, it needs electricity. There isn't an extension cord long enough to reach the ground from space, so Hubble runs on sunlight. This makes it the ultimate cordless power tool. On either side of the telescope's tube are two wing-like solar panels which convert sunlight into about 3,000 watts of electricity. That's enough power to light 30 household light bulbs. Hubble Space Telescope has five instruments that work together, or individually, to provide us with impressive images from the furthest depths of space. Hubble is made up of 3 cameras, spectrographs and guidance sensors. For more info on these instruments, click here. Hubble Space Telescope orbits about 600 kilometers above the Earth. It circles the Earth about every 97 minutes. Imagine pointing a laser on a dime 200 miles away and then holding it steady for hours or days. That's exactly how sophisticated and precise Hubble's pointing control system is. Once Hubble locks onto an object, sensors check for movement 40 times a second. If something moves, wheels that are constantly on the move change speeds to smoothly bring the telescope back to position. Hubble Space Telescope downloads everything onto optical computer disks. These provide a resource for current and future astronomers. One day's worth of observations would fill an encyclopedia. When the Hubble telescope was first launched, a mirror had warped so everything was out of focus. Three years later a team was sent up to the telescope and they fixed the problem.

Record-breaking blasts from unseasonable solar storms seen in late 2003 are just now reaching the edge of the Solar System, scientists reported on Thursday. More than a dozen coronal mass ejections – eruptions of super-heated gas triggered by tangled magnetic fields on the Sun’s surface – shot from the star over a period of 20 days last October and November. In the events, which pointed in different directions because of the Sun’s rotation, radiation and high-speed particles surged ahead of gas from the blasts themselves. On 28 and 29 October, that gas reached Earth in record time – about 20 hours, sweeping past the planet at five million miles per hour. “If you look at the overall speed of the events – the sheer momentum of it – it’s the biggest event we’ve measured in space,” University of Michigan astronomer Thomas Zurbuchen told reporters at a NASA teleconference. An unprecedented number of spacecraft tracked the blasts as they sped outward from the Sun, producing a trove of data that may help scientists predict the effects of future space storms. The blasts produced auroras as far south as Florida in the US, shut down power in a city in Sweden, and forced astronauts aboard the International Space Station to duck into a relatively well shielded service module. A few hours after reaching Earth, the blasts hit Mars, which has no global magnetic field to shield it from solar storms. The events disabled a radiation-monitoring instrument on the orbiting spacecraft Mars Odyssey. And computer simulations suggest they also blew off part of the planet’s upper atmosphere, an effect that may have helped erode the planet’s surface water over 3.5 billion years. “We know there used to be a lot more water than there is right now. Where did it go?” Zurbuchen said. “One of the key ideas people are talking about is the connection to these space storms.” The Ulysses spacecraft near Jupiter and the Cassini spacecraft near Saturn both detected radio waves when the blasts slammed into the planets’ magnetic fields. In April, the blasts – slowed to 1.5 million miles per hour – even caught up with the Voyager 2 probe, which has travelled about 7 billion miles from the Sun since its launch in 1977. And preliminary data suggest they may have reached the Voyager 1 spacecraft, nearly 9 billion miles from the Sun this Tuesday, eight months after erupting from the star. At those distances, the Sun’s magnetic influence begins to wane as solar wind particles come into contact with particles from interstellar space. The blasts are expected to temporarily expand – by 400 million miles – the boundary of this heliosphere, which they will probably reach by early 2005. “If the blast wave still has enough energy at that point, it can cause the interstellar material to radiate radio waves, which can tell us how far it is to the edge of interstellar space,” said Ed Stone of the California Institute of Technology. Researchers say predicting space storms has come a long way in recent years – they got a little advance warning in 2003 by measuring vibrations on the Sun’s surface from sunspots on the far side of the star. And using computer models, scientists accurately predicted when the blasts would reach the Voyager 2 probe, accounting for the slowing effects of interstellar material. “We got it to within a day,” said Justin Kasper of the Massachusetts Institute of Technology. “The neat thing is our models are getting sophisticated enough we can model out to the heliosphere.”

Sydney, Australia, Sep 17 (efe-epa).- Qantas airline on Thursday sold in 10 minutes all its seats for a “flight to nowhere” that will soar over some of Australia’s main tourist attractions for seven hours on Oct. 10, in response to restrictions imposed on domestic and international routes. With many of the internal borders closed in the oceanic country, the Australian company offers this flight that departs and returns to Sydney to fly over the red monolith Uluru, the Whitsundays Islands and the Great Barrier Reef on Oct. 10, Qantas said Thursday in a statement. The flight in a Boeing 787 Dreamliner aircraft, normally used on international routes, allows a trip to be made without passenger having to carry out the 14-day quarantine imposed on people residing in so-called “COVID-19 hotspots” when they travel to another state. Tickets for this flight, which features a menu catered by Australian chef Neil Perry, sold for between $572 and $2,754 and sold out in 10 minutes. The flight is “probably the fastest sold in the history of Qantas,” a company spokeswoman told EFE. Qantas has also decided to resume from November the 12-hour routes that it previously offered to fly over Antarctica aboard a Boeing 787 aircraft as a measure to mitigate the economic effects of COVID-19. In late August, Qantas said it is considering outsourcing its ground services due to the sharp decline in its operations due to the coronavirus pandemic, which could lead to the elimination of another 2,500 jobs. These cuts would be added to the reduction of 6,000 jobs that Australia’s largest airline announced in June as part of its restructuring plan due to the COVID-19 crisis. EFE-EPA

Rocket Lab is a David among Goliaths in the space race CEO Peter Beck on the future of commercial launches and not raining debris over national reserves Interview Rocket Lab is a relatively small player in a launcher marketplace dominated by governments and billionaires. However, despite some notable anomalies, the company is starting 2024 with a packed schedule and grand plans for the future. Boss Peter Beck is unfazed by his rivals. He tells The Register: "Rocket Lab is probably one of the few – if not the only – truly commercial providers, certainly publicly traded. Generally, our competitors are either the two richest men on the planet or government." With regard to reaching orbit and remaining a going concern, Beck is correct. Where other commercial outfits – such as Virgin Orbit – have failed, Rocket Lab continues to launch its Electron rockets despite some setbacks. Out of 42 flights, Rocket Lab has suffered four failures. A telemetry issue was at fault during Electron's very first test flight (named "It's a Test") in 2017. The others were related to problems with the second stage in 2020, 2021, and 2023. Following the failure in September 2023, the company was back in action within two months. "It is devastating to have a failure," says Beck. However, Rocket Lab is a commercial entity that can only stand down for a short time. "If we're not flying, we're not generating revenue. We're burning cash." Being almost completely vertically integrated means the team has diagnosed and resolved issues rapidly. "We don't have to rely on third parties," explains Beck. "If we want to open up an avionics box, have a look in there, and understand exactly what's going on, we just walk down the hallway and talk to the guy who designed it." The same applies to software. Well, we didn't explode the largest rocket ever created in a national reserve The approach can be contrasted with that adopted by government-backed organizations. Arianespace, for example, has famously struggled to return the Vega-C to flight after a failure during launch in 2022. The next launch is delayed to the end of 2024 at the earliest, pending redesigns. However, Rocket Lab has had its share of run-ins with regulators and government agencies, as have other commercial operators. The license for its Wallops launch pad was held up as the authorities scrutinized the company's abort system. That said, Beck holds no grudges, praising the US Federal Aviation Authority (FAA) in particular. "Yes, while there are some kinds of frustrations along the way, I would say that our experiences with the regulators have been positive." Unlike other commercial operators, which regularly lock horns with the authorities over launch plans. "Well, we didn't explode the largest rocket ever created in a national reserve." However, like other commercial operators, Rocket Lab intends to recover and potentially reuse its Electron boosters. It had planned to snatch descending rockets via helicopter but, after recovering some from the ocean, realized that a dunking in salt water perhaps wasn't so bad after all. Beck explains: "The assumption that we made that once the rocket gets dumped in the ocean, it's kind of all over, was correct. But actually, the issues that needed to be solved were relatively few. "It's kind of ironic that we were fishing [the Electron boosters] out of the middle of the ocean anyway, and we realized, 'Actually, this isn't so bad…' So we just pivoted to that method." SpaceX famously reuses its Falcon 9 rockets over and over again. Beck hopes that Rocket Lab will get to the point where a refurbished Electron might be reused, but also expects the lesson learned will be applied to the company's next rocket, the considerably heftier Neutron. Beck would not be drawn on specific dates for Neutron, only saying that testing was going well and milestones were being achieved. "This year," he says, "is a year of engine testing and major structure development and testing. Right now, everything's going fine, but when you get up to these big-scale tests, that's when you learn things." And Neutron will be reusable. Beck points to the economic advantage of reusability. "If you're developing disposable vehicles at this juncture, then you're developing a dead product." - Rocket Lab mission lost in the Paschen of the moment - Rocket Lab sets sights on 2024-2025 window for Venus mission - Rocket Lab launch streak goes up in smoke with 41st mission - Rocket Lab wants to dry off and reuse Electron booster recovered from the ocean Best not mention that to NASA with its SLS or Arianespace and the Ariane 6. "For government programs, especially programs with no experience in reusability, it's a fairly daunting task … the ability to pivot is not very strong; a number of these programs have been in development for decades." Rocket Lab also lacks the benefit – or not, as the case may be – of being the plaything of one of the richest people on the planet, although it did take investment in recent years. It also must make a return on that investment. Our two biggest competitors are the two wealthiest people on the planet. Do they need to be profitable? Arguably not. Beck says: "It's about aligning what you want to do with investors' interests. And investors' interests are incredibly simple. It's to make money! If you're trying to build a multi-generational space company, then, by definition, it has to be profitable. So the projects and the vision align with that. "Our two biggest competitors are the two wealthiest people on the planet. Do they need to be profitable? Arguably not. But we have to be, so that causes us to be efficient and to do things that ensure that." That said, Beck's dream of a mission to Venus continues to inch forward. While some focus on Mars, Beck has long proposed a flotilla of relatively inexpensive and simple probes to investigate Venus. However, as Beck puts it: "We've always seen it as a nights and weekends project." Sadly, pet projects have to go on the back burner in favor of looking after real customers. Rocket Lab has more than 20 Electron launches booked in 2024, and the infrastructure is in place to reach 50 or more. Hopefully, a mission to Venus might be quietly slipped in somewhere. As for the future, Beck jokes that "one year at Rocket Lab is like a dog year. So five years is an extraordinarily long time period to think about." He tells us he sees consolidation and full-service companies as the future. "The large, successful companies in the future are not going to be space companies that just build a satellite or just launch a rocket. They are going to be companies where you can design a spacecraft, build a spacecraft, launch a spacecraft, and operate a spacecraft. "I firmly believe that in the future, people will just want services from space. They don't want all the kerfuffle of building and owning and operating and launching a spacecraft." Rather than customers pitching up with a detailed spacecraft and payload specification, Beck's definition of success is a customer asking for some telecommunications over some region or other, and the future space company simply taking care of everything. "I think, ultimately, that's where it will all go." ®

Uber updates flying taxi initiatives at Elevate September 23, 2018 By UAV Canada Staff A range of news about the flying taxis program of Uber Technologies Inc. emerged after its second annual Elevate Summit, including the company’s plans to select a new international city to launch the project, a partnership with NASA, and a goal to start commercial aerial ride-sharing services in 2023. First, Reuters new agency reports Uber re-opened a contest to select a new international city to launch its UberAIR flying taxis service, because of delays and challenges with its initial Dubai selection. Dallas and Los Angeles were selected as its first launch cities. Reuters explains Uber is ready to consider cites with “a population of greater than two million people, with dispersed population hubs, an airport at least an hour away from the city centre and which is willing to back pooled ridesharing services.” Uber also reinforced key goals for getting the UberAIR service off the ground, including plans to begin testing its electric-powered vertical-takeoff-and-landing (eVTOL) vehicles in 2020. The company explains this will ideally lead to a 2023 start for its commercial aerial ride-sharing service. On May 8, NASA then announced it had reached a second space act agreement with Uber to explore concepts and technologies related to urban air mobility (UAM). Under this agreement, Uber will share its plans for implementing an urban aviation rideshare network. NASA will use the latest in airspace management computer modeling and simulation to assess the impacts of small aircraft – from delivery drones to passenger aircraft with vertical take-off and landing capability – in crowded environments. NASA explains this is its first such agreement specifically focused on modeling and simulation for UAM operations, also stating its definition of urban air mobility is a safe and efficient system for vehicles, piloted or not, to move passengers and cargo within a city. “NASA is excited to be partnering with Uber and others in the community to identify the key challenges facing the UAM market, and explore necessary research, development and testing requirements to address those challenges,” said Jaiwon Shin, associate administrator for NASA’s Aeronautics Research Mission Directorate. “Urban air mobility could revolutionize the way people and cargo move in our cities and fundamentally change our lifestyle much like smart phones have.” At its research facility at the Dallas Fort Worth (DFW) International Airport, NASA explains it will use the data supplied by Uber to simulate a small passenger-carrying aircraft as it flies through DFW airspace during peak scheduled air traffic. Analysis of these simulations will identify safety issues as these new aircraft take to the air in an already crowded air traffic control system. “The new space act agreement broadening Uber’s partnership with NASA is exciting, because it allows us to combine Uber’s massive-scale engineering expertise with NASA’s decades of subject matter experience across multiple domains that are key to enabling urban air mobility, starting with airspace systems,” said Jeff Holden, Uber’s chief product officer.

Body mounted germanium substrate solar cell arrays form the faces of many small satellite designs to provide the primary power source on orbit. High efficiency solar cells are made affordable for University scale satellite programs as triangular devices trimmed from wafer scale solar cells. The smaller cells allow the array designs to pack tightly around antenna mounts and payload instruments, giving the board design more flexibility. We are investigating the reliability of solar cells attached to FR-4 and carbon core laminate printed circuit boards. FR-4 circuit boards have significantly higher thermal expansion coefficients and lower thermal conductivities than germanium. This thermal expansion coefficient mismatch between the FR-4 board and the components used cause major concern for the power system when considering a failure of the solar cells, such as a series of cracked cells or faulty solder joints. These failures are most likely to happen with a longer orbital lifetime and longer exposure to the harsh environment the satellite will experience while in orbit. Carbon core laminates provide an advanced alternative because the core thickness can be selected to more closely match the device substrate, or at least provide a wider thermal expansion coefficient range to match the components on the board. We are also comparing various methods of attaching the solar cells to the printed circuit boards, using solder paste alone and in parallel with a silicone adhesive, considering the application of these adhesives by comparing the solder joints under x-ray when applied by screen printing versus stencil printing, and looking closely at the cleaning processes for array assembly. Storage, vacuum exposure, thermal cycling, functional and vibration testing will be used to compare the survivability and performance of the solar arrays.

Women are doing some pretty amazing things here on Earth, but women in the space sector are going the extra mile to create a stronger female presence in space and beyond. While, like on Earth, there’s more work to be done as far as equality and inclusiveness go, women have come a long way in staking out our own space within the space industry. There are programs that provide education and resources for women looking to get into the field, women are taking an active role on the International Space Station (ISS), and more women are making major decisions in the aerospace sector. One small step for women … The first female to ever go to space was Russian astronaut Valentina Tereshkova in 1963. NASA astronaut Mae Carol Jemison was the first female African-American to go to space back in 1987. The first woman to be on a crew for the ISS was Susan Helms, who was a flight engineer on the Expedition 2 mission in 2001. You may not recognize these names as much as their male counterparts like Neil Armstrong or Buzz Aldrin, but their accomplishments paved the way for women in the space sector. In October, the first all-female spacewalk took place outside the ISS with NASA astronauts Christina Koch and Jessica Meir taking part Koch has since broken a new duration record for a single space mission by a woman after she spent 328 days in space at the ISS. Back here on Earth, several women are running major aerospace companies. According to Yale Insights, three of the top five aerospace companies are headed by women, including Marillyn Hewson, the CEO of Lockheed Martin; Phebe Novakovic, the chairwoman and CEO of General Dynamics; and Kathy Warden, the CEO and president of Northrop Grumman. Lori Garver was only NASA’s second female deputy administrator when she held the title from 2009 to 2013. Now, her and her fellow co-founders run the Brooke Owens Fellowship Program, which pairs women with paid internships at aerospace companies like NASA, Boeing, Blue Origin, SpaceX, and more. “Programs that help put a focus on [women] can be very positive,” Garver told Digital Trends. “We’ve seen a great reception for hiring these women.” “Programs that help put a focus on [women] can be very positive.” Garver said that there is a waiting list of companies interested in participating in the program, which further reinforces that women have a place in space. “I’m really grateful and want to celebrate the success we’ve had, while at the same time, there’s still a long path ahead,” she said. “I’d like to see more focus on the value that space programs bring.” Another women-centered program is the Sensoria Space Program, which provides training, professional development, and research experience to female-led and female-majority crews. An all-women team just finished the program’s inaugural, two-week stint in a Mars habitat simulator last month. Dr. Sian Proctor was a part of last month’s simulation, as well as a member of the first crew at the same habitat in 2013. Back then, there were only three women. “To come back seven years later and to have an all-female crew, and to be around spectacular women who are doing amazing things … it gives me hope and joy to the future and being a part of the change that is happening,” she said. Finding an Oprah for space Getting these female-centered stories out in the open and allowing women to have the same opportunities as men when it comes to space exploration takes time. According to Space.com, of the 566 people who have flown into space so far, only 64 have been women, and of the 38 currently active NASA astronauts, only 12 are women. Even when women get opportunities, they are still faced with discrimination in a field that is male-dominated. “Women in our program have way too many stories still about being the only woman in their program and being mansplained,” Garver said. “We just all have to look at unintended biases and work to overcome them collectively.” Proctor said the solution is to bring women to the forefront of space and science efforts at conferences and speaking engagements, as well as in the media and entertainment industry. “Women in our program have way too many stories still about being the only woman in their program and being mansplained.” “If you really want big cultural change, then you need females in shows that are popular [and] that are talking about and doing science,” she said. An example Proctor used is that when we think of big names in the space and science industries, we immediately think of Neil deGrasse Tyson or Bill Nye. She said that we need females in those public-facing roles as well. “Who is the Oprah of the space community? There isn’t one,” she said. Proctor also said that recognizing all women of all races is especially crucial for inclusiveness in the space sector. “It’s important that women of color to also have a voice within the women in space movement,” Proctor said. “It gets bigger than just women … it gets to the point of equity, access, and inclusiveness.” The next generation of women in space Ultimately, the future of women in space is in the hands of women currently getting into the field. As more people understand that inclusiveness needs to expand in the industry beyond simply hiring more women, the change will happen. Proctor said it’s especially important for women to have the same experiences that men have had. “A lot of the conversation has been, ‘we’ve been to the moon, we’ve done that,’ but when we talk about access, really only a small number of white males have been to the moon,”she said. “Just because humans have done it, it denies the place of others in access to those experiences.” Luckily, NASA has plans to send the first female to the moon through its Artemis mission by 2024. For those little girls out there hoping to land on the moon one day, or even simply be treated as equals to their male counterparts, Proctor and Garver said that the future is still bright. “I encourage women to come into the field … we need them,” Garver said. “They are going to be able to make an impact, and I think there is a general openness to hiring and promoting [women] that I have not seen in my career.” “Don’t get discouraged,” Proctor said. “There are a lot of women who have come before you that are here to mentor you.” - How to watch two U.S. astronauts on a spacewalk at the ISS on Friday - How to watch NASA’s all-private crew launch to the ISS on Sunday - How to watch SpaceX launch mighty Falcon Heavy on Friday - How to watch SpaceX launch record-breaking Starship rocket on Thursday - How NASA’s astronaut class of 1978 changed the face of space exploration

Scientists have long known that Uranus' south pole has a swirling feature. NASA's Voyager 2 imaging of methane cloud tops there showed winds at the polar center spinning faster than over the rest of the pole. Voyager's infrared measurements observed no temperature changes, but the new findings, published in Geophysical Research Letters, do. Using huge radio antenna dishes of the Very Large Array in New Mexico, they peered below the ice giant's clouds, determining that the circulating air at the north pole seems to be warmer and drier - the hallmarks of a strong cyclone. Collected in 2015, 2021, and 2022, the observations went deeper into Uranus' atmosphere than any before. "These observations tell us a lot more about the story of Uranus. It's a much more dynamic world than you might think," said lead author Alex Akins of NASA's Jet Propulsion Laboratory in Southern California. "It isn't just a plain blue ball of gas. There's a lot happening under the hood." Uranus is showing off more these days, thanks to the planet's position in orbit. It's a long haul around the solar system for this outer planet, taking 84 years to complete a full lap, and for the last few decades the poles weren't pointed toward Earth. Since about 2015, scientists have had a better view and have been able to look deeper into the polar atmosphere. Ingredients for a Cyclone The cyclone on Uranus, compactly shaped with warm and dry air at its core, is much like those spotted by NASA's Cassini at Saturn. With the new findings, cyclones (which rotate in the same direction their planet rotates) or anti-cyclones (which rotate in the opposite direction) have now been identified at the poles on every planet in our solar system except for Mercury, which has no substantial atmosphere. But unlike hurricanes on Earth, cyclones on Uranus and Saturn aren't formed over water (neither planet is known to have liquid water), and they don't drift; they're locked at the poles. Researchers will be watching closely to see how this newly discovered Uranus cyclone evolves in the coming years. "Does the warm core we observed represent the same high-speed circulation seen by Voyager?" Akins asked. "Or are there stacked cyclones in Uranus' atmosphere? The fact that we're still finding out such simple things about how Uranus' atmosphere works really gets me excited to find out more about this mysterious planet." The National Academies' 2023 Planetary Science and Astrobiology Decadal Survey prioritized exploring Uranus. In preparation for such a mission, planetary scientists are focused on bolstering their knowledge about the mysterious ice giant's system.

Public awareness around the negative environmental impacts of flying has risen considerably over the last few years. However, the aviation industry continues to grow, and more people are flying now than ever before. There’s hope that new advancements in aviation technology will allow us to continue our flying habits while bringing carbon emissions down, making the business of air travel more environmentally friendly. But is the prospect of sustainable flights something we can count on, or just a lot of hot air? Electric engines are scheduled to start replacing gas engines on some short-haul commercial flights in 2022. Rather than burning jet fuel, these engines rely on a rechargeable battery to operate. Like electric car engines, they do not generate CO2 emissions and can be powered with renewable energy. However, the battery needed to fly an electric plane is much heavier than fuel and takes up much more space, significantly limiting the load that can be carried and the distance that can be travelled. This technology could only be used for flights of up to 1000 kilometres, as the battery would need to be re-charged after that. "The battery needed to fly an electric plane is heavier than fuel and takes up more space, limiting the load that can be carried and the distance travelled." For mid-range flights, hybrid engines are a less carbon-intensive possibility – but they would still have to use polluting jet fuel to operate. Unless there is a breakthrough in designing rechargeable batteries that are lighter and more durable, long-haul flights won’t benefit from this technology at all. According to the Air Transport Action Group, 80% of the aviation industry's emissions come from passenger flights longer than 1,500km. So if planes have to burn fuel to complete longer journeys, are there any ways to make it more sustainable? Biofuels are currently the most promising alternative to fossil fuels, but biofuels made from plants are typically monoculture crops, which are a disaster for biodiversity, and are a key driver of deforestation. Several airlines are now pursuing biofuel made from waste products, such as ethanol captured from the waste gases of steel mills. "Biofuels are a promising alternative to fossil fuels, but biofuels made from plants are typically monoculture crops, which are a disaster for biodiversity." While recycling all of our waste materials into energy sounds ideal, it isn’t without its drawbacks. Fossil fuels are still needed to create waste materials to begin with, and the process of making biofuel produces its own emissions. Additionally, synthetic fuels don’t behave in exactly the same way that fossil fuels do, so can’t be more than 50% of fuel used on a flight. As these biofuels are up to four times the price of fossil fuels, they are also fairly unpopular with airlines. Alternative fuels currently make up less than 1% of fuel used in the industry, so scaling up would be a massive challenge. If decarbonising jet fuel isn’t the answer, should we be looking at ways to reclaim the carbon after it has been pumped into the atmosphere? Carbon capture devices are already used on submarines and spacecraft. They rely on ‘scrubbers’ which absorb CO2 a similar way to plants. Direct Air Capture (DAC) is a process that would use scrubbing technology at a much larger scale, taking CO2 out of the air and storing or burying it in the ground. DAC is still in its early stages of development, and scaling up to make a global impact on flying emissions would require a huge amount of investment. Plus, the energy required to run such operations would be massive. One of the biggest problems with relying on carbon capture to offset the effects of flying is that CO2 isn’t the only harmful emission planes release into the air. Nitrogen oxide (NOx) is another greenhouse gas, as are the vapour contrails left behind by planes. These emissions are more harmful at high-altitude than if they were released at ground level, with roughly double the warming effect. "A big problem with relying on carbon capture to offset the effects of flying is that CO2 isn’t the only harmful emission planes release into the air." Time is Running Out We’re just scratching the surface here of a whole industry devoted to decreasing the negative effects of flying. There are many more experimental technologies that have been proposed to help curb the crisis, including innovative new wing designs, solar planes and the introduction of hydrogen fuel cells. The problem shared by all of these technologies is that they are in the early stages of development and are relatively small-scale. At the current rate of air travel expansion and with the lack of any cheap, quick fixes on the horizon, it seems as though an increase in aviation emissions is inevitable. As we have been given 10 years to make significant reductions to our carbon emissions before the effects of climate change become irreversible, we really can’t afford to let this happen. Currently, there is no silver bullet technology that will reduce air travel carbon emissions to zero by 2050. The only way to significantly and realistically reduce emissions is if we all make the decision to fly less.

A Vertical Test Stand (VTS) is a type of equipment used to test the vertical launch and ascent capabilities of a rocket or other vertical launch vehicle. The VTS provides a controlled environment for conducting pre-flight tests and evaluations of the vehicle's propulsion and guidance systems, as well as its structural integrity. The VTS also helps to verify the performance of the vehicle's engine and control systems, and to identify any issues that may need to be addressed before the vehicle is ready for actual flight. The VTS typically consists of a sturdy, upright structure that supports the vehicle, and various instrumentation and control systems to monitor and control the vehicle during testing. There are many resources available for learning about Vertical Test Stands (VTS) and the processes involved in testing rocket and launch vehicle systems. Here are a few places where you might find tutorials and educational resources: Online Courses: Platforms like Coursera, Udemy, and edX offer courses on space engineering and rocket propulsion that may cover the topic of Vertical Test Stands.

Genesis ("Beresheet" in Hebrew), Israel's first spacecraft to the Moon, has some complications. After launching in the morning, SpaceIL and Israel Aerospace Industries engineers found that sensors on the vessel needed for navigation were too sensitive to sunlight. They discovered another problem with the spacecraft's robot on Monday, which could delay its achievement of the moon. Around midnight from Monday to Tuesday planned another maneuver to increase the orbital radius around the Earth. The maneuver was to be carried out automatically when the spacecraft was in the sky, where it would not have had contact with the controllers on the ground. However, during the preparation for maneuver, the computer's computer performed an unplanned reboot. Restart canceled the maneuver, and he continued his initial orbit. The engineers responsible for Genesis operations analyze data and try to understand what caused the reboot and what its consequences might be. Whenever Genesis completes the orbit, it performs another maneuver designed to move it further from the ground, releasing its engines within three minutes. That's how it will eventually reach the moon, with orbits at consistently increasing distances from the Earth along a trajectory that resembles an elliptical spiral. The advantage of this method, which is based on the gravitational attraction of the Earth, lies in the fact that it saves fuel. Lack of maneuver means the postponement of the Genesis Moon landing. Genesis was built by the private non-profit group SpaceIL in collaboration with Israel Aeronautics Industries. Director-General of SpaceIL Ido Anteby told reporters in a conference call that Genesis systems navigate the navigation and calibrate the navigation systems before maneuvering. "At this stage, the computer of the spacecraft had an independent reset, so the maneuver was canceled," he said. Once engineers understand what caused the problem with the computer, they will decide when to try to repeat the maneuver, Anteby said. Oper Donor, head of the IAI space division, said he was not particularly concerned now: "The sooner we will understand what has happened, we will be able to prevent the recurrence of the problem." An orbital maneuvering plan included several days for delays, so if the problem is fixed within the next two days, the spacecraft could reach the Moon according to the start schedule, said two. The maneuver is not the first downturn faced by Genesis. The first problem was one of the positioning systems called stellar trackers. These are sensors that find stars around the spacecraft to determine its location. After launching, it became clear that trackers are more sensitive than expected to sunlight, which may complicate the detection of other stars. While star-trackers focus on areas of the sky, where sunlight does not interfere, Doron explained that these changes could be associated with an unplanned computer reboot. Genesis was successfully launched late in the evening on Thursday from Cape Canaveral. After 33 minutes, he separated from the carrier rocket and began to rotate the ground. It is expected to land on the Moon on April 11 and would be the smallest car to accomplish that. One of the founders of SpaceIL, Yar Bash, said that "the launch was cool, but the hard part is ahead of us." He will be 6.5 million kilometers, the longest trajectory of any spacecraft that has gone from Earth to the Moon. The cost of $ 100 million is significantly lower than the previous expeditions. If it succeeds, Israel will become the fourth country to land on the Moon.

Saturn's rings obscure part of Titan's colorful visage in this image from NASA's Cassini spacecraft. The south polar vortex that first appeared in Titan's atmosphere in 2012 is visible at the bottom of this view. See PIA14919 and PIA14920 to learn more about this mass of swirling gas around the pole in the atmosphere. The south polar vortex was not present earlier in the mission (see Titan Beyond the Rings and Titan Upfront). Titan is 3,200 miles (5,150 kilometers) across. The northern part of the moon's atmosphere visible here includes the north polar hood, a cap of haze looking slightly darker than the rest of the atmosphere and seen near the top of the moon. See Haze Layers on Titan to learn more about the north polar hood. Parts of the rings appear dark near the center of this view because of the shadow cast by the planet. However, a sliver of illuminated Titan can be seen through the Cassini Division in the rings near the middle of this darkness. This view looks toward the northern, sunlit side of the rings from just above the ring plane. Images taken using red, green and blue spectral filters were combined to create this natural color view. The images were obtained with the Cassini spacecraft narrow-angle camera on May 16, 2012, at a distance of approximately 1.9 million miles (3 million kilometers) from Titan. Image scale is 11 miles (18 kilometers) per pixel on Titan. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.

The future of aerial warfare might involve fighter jet-sized drones that operate alongside manned jets using artificial intelligence software. According to NBC News, research and testing are already underway on a project that would put the large and very sophisticated drones in the air, perhaps within just a few years. Boeing, for example, is working on the Airpower Teaming System. And the XQ-58A Valkyrie, a drone that can travel as fast as 652 mph and was built by Kratos Unmanned Aerial Systems, is already being tested. The U.S. Air Force Research Laboratory, based at Wright-Patterson Air Force Base in Ohio, is trying to develop the next-generation technology through its Skyborg program. "These drone aircraft are a way to get at that in a more cost-effective manner, which I think is really a game-changer for the Air Force," Paul Scharre of the Center for a New American Security told NBC. Will Roper, an assistant secretary of the U.S. Air Force who is working on the AI project, told NBC the unmanned jets would have the ability to adapt to whoever is flying with them. "I wouldn't be surprised if the AI becomes tailored to individual pilots," he said. "They're actually training their own AI that augments their strengths and weaknesses." The unmanned jets, according to the report, could be used to draw fire away from the human-piloted planes — which can cost more than $100 million, compared to a few million for one of the drones. They could eventually be armed as well and could fire upon targets, but that feature would likely need input from a human. The technology is just one of the many ideas being looked at as the military tries to advance to the future of warfare. Other things in development include exoskeletons, drone swarms, and high-tech guns and ammunition. © 2023 Newsmax. All rights reserved.

Funding urged for missile plan / Pentagon panel wants an even more ambitious defense system 2001-04-22 04:00:00 PDT Washington -- The Bush administration should embark on an ambitious missile defense program that includes core elements of the Clinton anti-missile plan, despite daunting technical challenges, a Pentagon advisory panel is recommending. A key advisory committee organized by Defense Secretary Donald Rumsfeld is urging the new administration to continue funding the Clinton team's limited, ground-based system, while supplementing it with anti-missile systems based in the sea, on aircraft and in space. While the committee's recommendations are rendered in only the broadest strokes, they clearly would result in a system that would be implemented on a vast scale. Critics say it would cost taxpayers hundreds of billions of dollars, though missile defense supporters contend that a large-scale system could be built on an annual budget of about $10 billion. Former President Bill Clinton's program was expected to cost about $60 billion. Bush administration officials have made missile defense a top priority. But their plans to develop a blueprint have been complicated by the fact that the Clinton administration's system, which they have criticized, is furthest along in development, while there has been relatively little progress on the sea- based and space-based technologies they prefer. The Bush administration is not expected to unveil its final plan for several months. But the panel's March 30 report, which has not been made public, is generally consistent with the approach sketched out by Bush and his aides since last year's presidential campaign. They have argued that Clinton's plan is not ambitious enough and that the administration should seek to go further to explore the other deployment options. The advisory panel's report says that, while an aggressive missile defense program would carry risk of technical failure and unforeseen costs, the administration should "accept program risk to facilitate early deployment." It urges the administration to develop systems that can destroy enemy missiles at three stages of flight: just after launch, in mid-flight and at the end of their trajectory. The blueprint closely reflects the desires of missile defense advocates, who want the administration to commit the nation quickly to a large system. As a first step, they argue that a stop-gap system, even if not perfect, could knock down missiles and give pause to "rogue" nations who might be considering attacking the United States. The defense panel urged the administration to "field the first mid-course system as soon as possible," then expand it later. The panel is one of the most important of 16 committees conducting a secret top-to-bottom review of the U.S. military at Rumsfeld's request. The administration is not bound to follow the advice of the panel, known as the Transformation Task Force. But the committee has had access to the latest Pentagon information on the subject and may have significant influence on the administration's final decision. Rear Adm. Craig Quigley, the Pentagon's chief spokesman, downplayed the panel's findings, describing the recommendations as "the interim report of one group of individuals." Missile defense critics who oppose the system include arms control advocacy groups and those who fear it will result in the casting aside of international arms control treaties. Many of those critics have predicted the plan also would run into insurmountable technical problems and run up huge costs.

Hey all. Haven't been been around a lot the past little bit. Home, work, and club duties have had me too busy to really build. But a new project just hit me. I have to build two rockets for the US Air Force JROTC command and I only have 30 days to do it. I need some CNC parts yesterday. My go to in the past has been Nat, but I have heard he's gotten difficult to reach. Who else can make custom CNC ply parts for me? I'm pretty desperate at the moment as my time is clicking away. Thanks a ton!

Data Construction Workflow

finefineweb-data-workflow

The data construction workflow can be summarized as follows:

  1. Deduplicate: The FineWeb dataset is deduplicated using exact deduplication and MinHash techniques to remove redundant data.

  2. URL Labeling: Root URLs from FineWeb are counted, and the top 1 million URLs are labeled using GPT-4. This step generates DoI (Domain-of-Interest) Coarse-Grained URLs and DoNI (Domain-of-Non-Interest) Coarse-Grained URLs as seed data sources.

  3. Coarse Recall:

    a. Based on the labeled root URLs, data is sampled for each domain.

    b. The sampled data is labeled using Qwen2-7B-Instruct, producing 500K DoI Positive Data and 500K DoI Negative Data (note that for N>1 iterations, each 500K samples are composed of 250K sampled original seed data and 250K refined data after Fine Recall).

    c. A binary FastText model is trained per domain using the labeled data.

    d. The FastText model performs coarse recall on FineWeb, generating Coarse DoI Data.

  4. Fine Recall:

    a. The Coarse DoI Data is labeled using Qwen2-72B-Instruct to produce 100K DoI Positive Data and 50K DoI Negative Data, with the latter further augmented with 50K negative samples from earlier FastText training.

    b. A BERT model is trained using this labeled data.

    c. The BERT model performs fine recall on the Coarse DoI Data, producing a refined dataset, which is the DoI subset of FineFineWeb.

  5. Coarse-Fine Recall Iteration: The workflow of coarse and fine recall iterates for 3 rounds with the following adjustments:

    a. FastText is re-trained using updated seed data, which combines BERT-recalled samples, BERT-dropped samples, and previously labeled seed data.

    b. The BERT model keeps frozen during subsequent iterations.

    c. Steps for training FastText, coarse recall, and fine recall are repeated without re-labeling data with Qwen2-Instruct models.

Domain-Domain Similarity Analysis

  1. Perform proportional weighted sampling of the domain subsets based on the sample size of each domain, with a total of 1 billion tokens sampled from the domain subsets.
  2. Use the BGE-M3 model to compute the embeddings of the samples in each domain subset, referred to as domain embeddings.
  3. Use the BGE-M3 model to compute the embeddings of the samples in each benchmark, referred to as benchmark embeddings (bench embeddings).
  4. Calculate the MMD distance and the Wasserstein distance between the domain embeddings and the benchmark embeddings.

domain-benchmark similarity

The results above reveal the following observations:

  1. The two code-related benchmarks, MBPP and HumanEval, exhibit relatively large distances from nearly all domains, indicating that the proportion of code data in the training set is relatively small. Notably, their distance to the mathematics domain is comparatively smaller, suggesting a certain degree of overlap between mathematics data and code data.
  2. Benchmarks such as Hellaswag, ARC, MMLU, and BoolQ have distances that are close to almost all domains, except for the gamble domain. This indicates that the samples in these benchmarks involve synergetic effects across multiple domains of knowledge, with a wide distribution.
  3. GSM8K and TriviaQA show significant discrepancies with a small number of domains, suggesting that the distribution differences between domains are more pronounced for samples involving grade-school mathematics and fact-based question answering. Some domains contain a substantial amount of this type of data, while others do not.
  4. The gamble domain exhibits substantial differences from other domains and has large distances from all benchmarks, indicating that pretraining data related to gambling provides limited benefits for these benchmarks.

Domain-Domain Duplication

Let D1,D2,,DND_1, D_2, \dots, D_N represent NN distinct domains, where we select top-20 URLs for each domain DiD_i, denoted as {Ui1,Ui2,,Ui20}\{U_{i1}, U_{i2}, \dots, U_{i20}\},. The total set of URLs across all domains is represented as U\mathcal{U}, and the total number of URLs is M=UM = |\mathcal{U}|.

For each URL UkUU_k \in \mathcal{U}, the term frequency (TF) is defined as the proportion of UkU_k in the total set of URLs: TF(Uk)=count(Uk)M\text{TF}(U_k) = \frac{\text{count}(U_k)}{M}

where count(Uk)\text{count}(U_k) is the number of times UkU_k appears in U\mathcal{U}. Additionally, the document frequency KkK_k of UkU_k is the number of domains in which UkU_k appears. Based on this, the inverse document frequency (IDF) is calculated as: IDF(Uk)=log(NKk)\text{IDF}(U_k) = \log(\frac{N}{K_k})

The TF-IDF value for each URL UijU_{ij} in a specific domain DiD_i is then computed as: TF-IDF(Uij)=TF(Uij)×IDF(Uij)\text{TF-IDF}(U_{ij}) = \text{TF}(U_{ij}) \times \text{IDF}(U_{ij})

domain-domain URL duplication

Using the TF-IDF values of all URLs within a domain, the domain-domain duplicate rate can be analyzed by comparing the distribution of TF-IDF values across domains. If a domain has many URLs with high TF-IDF values, it indicates that the domain’s URLs are relatively unique and significant within the entire set of URLs. Conversely, if a domain has many URLs with low TF-IDF values, it suggests that the domain's URLs are more common across other domains. Analyzing these values helps assess how similar or redundant a domain's content is in relation to others based on its URL composition.

As shown in the figure, most domains have low duplication rates, except for topicality, pet, and atmospheric science.

Domain-Benchmark BPC-Acc Correlation

Experimental method: Using 28 models (see the paper), we first calculate BPC for all domains to obtain a model ranking RDR_D. Similarly, we compute scores across all benchmarks to obtain a model ranking RMR_M. We then calculate the Spearman correlation between RDR_D and RMR_M.

domain-benchmark BPC-Acc correlation

  • For benchmarks like ARC, MMLU, GSM8K, HumanEval, and MBPP, STEM-related domains show higher correlation rankings, particularly mathematics, physics, and systems science.
  • For TriviaQA, which emphasizes factual knowledge over reasoning, domains rich in world knowledge such as literature, history, and library science demonstrate higher correlation rankings.
