The U.S. Court of Federal Claims ruled against Jeff Bezos' Blue Origin in the company's lawsuit versus NASA over a lucrative astronaut lunar lander contract awarded to Elon Musk's SpaceX earlier this year. Federal judge Richard Hertling sided with the defense in his ruling, completing a months-long battle after Blue Origin sued NASA in August. From a report: Blue Origin, NASA, and SpaceX did not immediately respond to requests for comment on the ruling. NASA in April awarded SpaceX with the sole contract for the agency's Human Landing System program under a competitive process. Worth $2.9 billion, the SpaceX contract will see the company use its Starship rocket to deliver astronauts to the moon's surface for NASA's upcoming Artemis missions.

Joshua Chou writes via The Conversation: Last month the Australian Space Agency announced plans to send an Australian-made rover to the Moon by as early as 2026, under a deal with NASA. The rover will collect lunar soil containing oxygen, which could eventually be used to support human life in space. Although the deal with NASA made headlines, a separate mission conducted by private companies in Australia and Canada, in conjunction with the University of Technology Sydney, may see Australian technology hunting water on the Moon as soon as mid-2024. If all goes according to plan, it will be the first rover with Australian-made components to make it to the Moon.

The ten-kilogram rover, measuring 60x60x50cm, will be launched on board the Hakuto lander made by ispace, a lunar robotic exploration company based in Japan. The rover itself, also built by ispace, will have an integrated robotic arm created by the private companies Stardust Technologies (based in Canada) and Australia's EXPLOR Space Technology (of which I am one of the founders). Using cameras and sensors, the arm will collect high-resolution visual and haptic data to be sent back to the mission control centre at the University of Technology Sydney. It will also collect information on the physical and chemical composition of lunar dust, soil and rocks -- specifically with a goal of finding water. We know water is present within the Moon's soil, but we have yet to find a way to extract it for practical use.

"NASA scientists have just published a commentary article in Nature calling for a framework for reporting extraterrestrial life to the world," reports Cosmos magazine (in an article shared by Slashdot reader Tesseractic): "Our generation could realistically be the one to discover evidence of life beyond Earth," write NASA Chief Scientist James Green and colleagues. "With this privileged potential comes responsibility. As life-detection objectives become increasingly prominent in space sciences, it is essential to open a community dialogue about how to convey information in a subject matter that is diverse, complicated and has a high potential to be sensationalised..."

Green and colleagues argue that...we should reframe such a discovery, so it isn't presented as a single moment when aliens are announced to the world. Instead, it should be seen as a progressive endeavour, reflecting the process of science itself. "If, instead, we recast the search for life as a progressive endeavour, we convey the value of observations that are contextual or suggestive but not definitive and emphasise that false starts and dead ends are an expected part of a healthy scientific process," they write. This will involve scientists, technologists and the media talking to each other to agree firstly on objective standards of evidence for life, and secondly on the best way to communicate that evidence.

This, they say, should preferably be done now before a detection of life is made, rather than scramble to put it together in the aftermath.
"The team kickstarts the conversation by proposing a 'confidence of life detection' (CoLD) scale, which contains seven steps taking us from first exciting potential detection of life to definitive confirmation," Cosmos points out. (With the stages including the discoveries of unquestionable biosignatures, a habitable environment, and then corroborating evidence.) Cosmos argues that "This is an increasingly important conversation to have — because experts think that the odds aliens exist are high."

And they close their article by quoting NASA's team. "Whatever the outcome of the dialogue, what matters is that it occurs. In doing so, we can only become more effective at communicating the results of our work, and the wonder associated with it."

NASA is calling on any interested humans to contribute to the machine learning algorithms that help Perseverance get around. All you need to do is look at some images and label geological features. ExtremeTech reports: The project is known as AI4Mars, and it's a continuation of a project started last year using images from Curiosity. That particular rover arrived on Mars in 2012 and has been making history ever since. NASA used Curiosity as the starting point when designing Perseverance. The new rover has 23 cameras, which capture a ton of visual data from Mars, but the robot has to rely on human operators to interpret most of those images. The rover has enhanced AI to help it avoid obstacles, and it will get even better if you chip in.

The AI4Mars site lets you choose between Opportunity, Curiosity, and the new Perseverance images. After selecting the kind of images you want to scope out, the site will provide you with several different marker types and explanations of what each one is. For example, the NavCam asks you to ID sand, consolidated soil (where the wheels will get good traction), bedrock, and big rocks. There are examples of all these formations, so it's a snap to get started.

Nasa's Juno mission, the solar-powered robotic explorer of Jupiter, has completed its five-year prime mission to reveal the inner workings of the Solar System's biggest planet. The most recent findings from these measurements have now been published in a series of papers, revealing the three-dimensional structure of Jupiter's weather systems -- including of its famous Great Red Spot, a centuries-old storm big enough to swallow the Earth whole. The Conversation reports: Jupiter's Great Red Spot has had a hard time in recent years. [...] But fans of the storm can take comfort from Juno's latest findings. In 2017, Juno was able to observe the red spot in microwave light. Then, in 2019, as Juno flew at more than 200,000 kilometers per hour above the vortex, Nasa's Deep Space Network was monitoring the spacecraft's velocity from millions of kilometers away. Tiny changes as small as 0.01 millimeters per second were detected, caused by the gravitational force from the massive spot. By modeling the microwave and gravity data, my colleagues and I were able to determine that the famous storm is at least 300 km (186 miles) deep, maybe as deep as 500 km (310 miles). That's deeper than the expected cloud-forming "weather layer" that reaches down to around 65 km (40 miles) below the surface, but higher than the jet streams that might extend down to 3,000 km (1,864 miles). The deeper the roots, the more likely the Red Spot is to persist in the years to come, despite the superficial battering it has been receiving from passing storms. To place the depth in perspective, the International Space Station orbits ~420 km (260 miles) above Earth's surface. Yet despite these new findings, the spot could still be a "pancake-like" structure floating in the bottomless atmosphere, with the spot's 12,000 km (7,456 mile) width being 40 times larger than its depth.

In the cloud-forming weather layer, Juno's microwave antennae saw the expected structure of belts and zones. The cool zones appeared dark, indicating the presence of ammonia gas, which absorbs microwave light. Conversely, the belts were bright in microwave light, consistent with a lack of ammonia. These bright and dark bands in the weather layer were perfectly aligned with the winds higher up, measured at the top of the clouds. But what happens when we probe deeper? The temperature of Jupiter's atmosphere is just right for the formation of a water cloud around 65 km (40 miles) down below the cloud tops. When Juno peered through this layer, it found something unexpected. The belts became microwave-dark, and the zones became microwave-bright. This is the complete reverse of what we saw in the shallower cloudy regions, and we are calling this transition layer the "jovicline" -- some 45-80 km (28-50 miles) below the visible clouds. [...] The jovicline may separate the shallow cloud-forming weather layer from the deep abyss below. This unexpected result implies something is moving all that ammonia around.

One possibility is that each jet stream is associated with a "circulation cell," a climate phenomenon that moves gases around via currents of rising and falling air. The rising could cause ammonia enrichment, and the sinking ammonia depletion. If true, there would be about eight of these circulation cells in each hemisphere. [...] Other meteorological phenomena might be responsible for moving the ammonia around within this deep atmosphere. For example, vigorous storms in Jupiter's belts might create mushy ammonia-water hailstones (known as "mushballs"), which deplete ammonia within the shallow belts before falling deep, eventually evaporating to enrich the belts at great depths.

A major solar flare erupted from the sun on Thursday in the strongest storm yet of our star's current weather cycle. Space.com reports: The sun fired off an X1-class solar flare, its most powerful kind of flare, that peaked at 11:35 a.m. EDT (1535 GMT), according to an alert from the U.S. Space Weather Prediction Center (SWPC), which tracks space weather events. The flare caused a temporary, but strong, radio blackout across the sunlit side of Earth centered on South America, the group wrote in an statement. NASA officials called the solar eruption a "significant solar flare," adding that it was captured in real-time video by the space agency's Solar Dynamics Observatory.

A coronal mass ejection from the flare, a huge eruption of charged particles, could reach Earth by Saturday or Sunday (Oct. 30-31), just in time for Halloween, SpaceWeather.com reported. The eruption could supercharge Earth's northern lights and potentially interfere with satellite-based communications. [...] Thursday's flare appeared to also spawn a coronal mass ejection, SWPC officials said. [...] The sun is in the early days of its current solar activity cycle, each of which lasts 11 years. The current cycle, called solar cycle 25, began in December 2019.

Blue Origin, the rocket and space tourism company founded by Jeff Bezos, is proposing a massive new commercial space station called "Orbital Reef" that could be used to host science experiments, vacation getaways, and potentially even in-space manufacturing. CNN reports: The company plans to work alongside startup Sierra Space to bring the space station to fruition, and Boeing plans to design a research module on the station, though there are no guarantees the companies can make it happen. Such projects are still exorbitantly expensive and risky, likely costing in the tens of billions of dollars and requiring multiple safe launches before a human ever even floats aboard. Blue Origin and Sierra Space plan to co-finance the space station, though executives declined to give an all-in cost estimate during a press conference Monday. They did add that they are expecting to sign on NASA as an anchor tenant, though it's not exactly clear how such a partnership could take shape.

Blue Origin hopes Orbital Reef could be operational in the late 2020s, though it will have to get quite a bit done to make that happen. The company has only managed a few crewed suborbital flights so far, much like NASA first achieved back in the early 1960s, and it has yet to put a spacecraft in orbit, let alone a person. A space station would take a major leap. New Glenn, the Blue Origin-built rocket that is expected to be powerful and large enough to haul the biggest portions of the space station to orbit, is not yet operational, and its maiden flight was recently delayed to at least late 2022. The orbital reef will be able to host up to 10 people and will have roughly the same internal volume as the ISS.

NASA's Perseverance rover has recorded up to five hours of sounds on the Mars, giving engineers a sense of how the Red Planet sounds different from Earth. Space.com reports: NASA now has a Perseverance rover website filling up with Martian audio, ranging from wind gusts to the sounds of rover driving as it seeks spots to hunt for the signs of life on the Red Planet. In March, we even heard its laser "snapping" (sadly, no pew-pew noise was evident.)

"It's like you're really standing there," Baptiste Chide, a planetary scientist who studies data from the Perseverance microphones, said in a statement from NASA's Jet Propulsion Laboratory (JPL). "Martian sounds have strong bass vibrations, so when you put on headphones, you can really feel it. I think microphones will be an important asset to future Mars and solar system science," added Chide, who works at France's Institute of Research in Astrophysics and Planetology. The SuperCam mics have been especially helpful for JPL to learn more about the environment in Jezero Crater, where Perseverance has been roaming for about seven Earth months. In May, Perseverance was able to hear the sound of the Ingenuity drone's rotors buzzing from a distance of 262 feet away. "The audio has been useful for investigations ranging from how sound propagates on Mars, and keeping Perseverance well-maintained," the report adds.

"Humanity will return to the lunar surface in 2024 as part of the Artemis program," writes the Auto Evolution site. "However, before NASA begins shuttling people to our natural satellite, it has to build a network there that will go beyond Earth's low orbit and connect space to Earth in a sort of Internet connection..." The network's name? LunaNet: Astronauts will be able to use the LunaNet via numerous nodes and communicate with the crew on and around the Moon in the same manner that we use Wi-Fi here on Earth. In addition, missions using the network will have access to position and time signals, allowing astronauts and rovers to navigate the rugged lunar terrain and return to their base. LunaNet will also use space-weather instruments to identify potentially dangerous solar activity, such as flares that erupt from the Sun and send harsh radiation towards the astronauts. With this new connectivity, the crew can be directly alerted. This will cut down the time it takes for network management on Earth to do so. These warnings will be comparable to the ones we receive on our phones when there is hazardous weather. The architecture's capabilities will also include a lunar search and rescue capability...

Researchers could also use LunaNet antennas to peer into deep space and search for radio signals from distant celestial objects. Altogether, the architecture's capabilities will give scientists a new platform to test space theories, allowing them to extend their scientific knowledge. Recently, NASA released the "Draft LunaNet Interoperability Specification" in order to kickstart the development of this new "lunar internet." Technical discussions among industry experts from around the world are expected to follow.

"Unplanned thruster firings by a Russian spacecraft briefly knocked the International Space Station off-kilter Friday, the second such incident in less than three months," reports Space.com: The spacecraft involved today was the Soyuz MS-18, which is scheduled to bring cosmonaut Oleg Novitskiy, film director Klim Shipenko and actor Yulia Peresild back to Earth early Sunday morning (Oct. 17)... "Within 30 minutes, flight controllers regained attitude control of the space station, which is now in a stable configuration," NASA officials wrote in an update this afternoon. "The crew was awake at the time of the event and was not in any danger."

The orbiting lab briefly tilted from its normal orientation this morning by 57 degrees, according to the Russian news agency Interfax, which cited communications between Novitskiy and Vladimir Solovyov, the flight director of the station's Russian segment.

Space station managers don't yet know what caused the anomalously long firing... It's also unclear why the MS-18's thrusters stopped firing, though the station's handlers have some ideas. "We think — and we haven't got confirmation — we think the thrusters stopped firing because they reached their prop[ellant] limit," NASA flight director Timothy Creamer told agency astronauts shortly after the thrusters shut down, according to The New York Times. "Moscow is checking into it and doing their data analysis."

In an article for The Conversation, Noah Wardrip-Fruin writes about how Computer Space marked the start of the $175 billion video game industry we have today when it debuted on Oct. 15, 1971 -- and why you probably haven't heard of it. From the report: Computer Space, made by the small company Nutting Associates, seemed to have everything going for it. Its scenario -- flying a rocket ship through space locked in a dogfight with two flying saucers -- seemed perfect for the times. The Apollo Moon missions were in full swing. The game was a good match for people who enjoyed science-fiction movies like "2001: A Space Odyssey" and "Planet of the Apes" and television shows like "Star Trek" and "Lost in Space," or those who had thrilled to the aerial combat of the movies "The Battle of Britain" and "Tora! Tora! Tora!" There was even prominent placement of a Computer Space cabinet in Charlton Heston's film "The Omega Man." But when Computer Space was unveiled, it didn't generate a flood of orders, and no flood ever arrived. It wasn't until Computer Space's makers left the company, founded Atari and released Pong the next year that the commercial potential of video games became apparent. The company sold 8,000 Pong units by 1974.

Nolan Bushnell, who led the development of both Computer Space and Pong, has recounted Computer Space's inauspicious start many times. He claimed that Computer Space failed to take off because it overestimated the public. Bushnell is widely quoted as saying the game was too complicated for typical bar-goers, and that no one would want to read instructions to play a video game. [...] At about the same time Computer Space debuted, Stanford University students were waiting in line for hours in the student union to play another version of Spacewar!, The Galaxy Game, which was a hit as a one-off coin-operated installation just down the street from where Bushnell and his collaborators worked. [...] Key evidence that complexity was not the issue comes in the form of Space Wars, another take on Spacewar! that was a successful arcade video game released in 1977.

Why were The Galaxy Game and Space Wars successful at finding an enthusiastic audience while Computer Space was not? The answer is that Computer Space lacked a critical ingredient that the other two possessed: gravity. The star in Spacewar! produced a gravity well that gave shape to the field of play by pulling the ships toward the star with intensity that varied by distance. This made it possible for players to use strategy -- for example, allowing players to whip their ships around the star. Why didn't Computer Space have gravity? Because the first commercial video games were made using television technology rather than general-purpose computers. This technology couldn't do the gravity calculations. The Galaxy Game was able to include gravity because it was based on a general-purpose computer, but this made it too expensive to put into production as an arcade game. The makers of Space Wars eventually got around this problem by adding a custom computer processor to its cabinets. Without gravity, Computer Space was using a design that the creators of Spacewar! already knew didn't work. Bushnell's story of the game play being too complicated for the public is still the one most often repeated, but as former Atari employee Jerry Jessop told The New York Times about Computer Space, "The game play was horrible."

Artificial intelligence expert Peter Norvig is joining the Stanford Institute for Human-Centered AI this fall as a Distinguished Education Fellow, with the task of developing tools and materials to explain the key concepts of artificial intelligence. From a blog post: Norvig helped launch and build AI at organizations considered innovators in the field: As Google's director of research, he oversaw the tech giant's search algorithms and built the teams that focused on machine translation, speech recognition, and computer vision. At NASA Ames, his team created autonomous software that was the first to command a spacecraft, and served as a precursor to the current Mars rovers. Norvig is also a well-known name in AI education. He co-wrote Artificial Intelligence: A Modern Approach, an introductory textbook used by some 1,500 universities worldwide, and he's taught hundreds of thousands of students through his courses on online education platform Udacity. In this interview, he discusses his move to Stanford, building a human-focused AI curriculum, and broadening access to education. When asked why he's leaving Google, Norvig said: "Throughout my career I've gone back and forth between the major top-level domains: .edu, .com, and .gov. After 20 years with one company and after 18 months stuck working from home, I thought it was a good time to try something new, and to concentrate on education."

IEEE Spectrum reports that air traffic controllers for America's Federal Aviation Administration "were confused and frustrated by an increase in military tests that interfered with GPS signals for civilian aircraft, public records show."

The incidents happened for controllers supervising flights over Arizona, New Mexico and Texas, according to their report (shared by Slashdot reader schwit1): In March and April this year, flight controllers at the Albuquerque Air Route Traffic Control Center filed reports on NASA's Aviation Safety Reporting System (ASRS), a forum where aviation professionals can anonymously share near misses and safety tips. The complaints accused the FAA of denying controllers permission to ask the military to cut short GPS tests adversely affecting commercial and private aircraft. These so-called "stop buzzer" (or "cease buzzer") requests are supposed to be made by pilots only when a safety-of-flight issue is encountered. "Aircraft are greatly affected by the GPS jamming and it's not taken seriously by management," reads one report. "We've been told we can't ask to stop jamming, and to just put everyone on headings."

In a second report, a private jet made a wrong turn into restricted airspace over the White Sands Missile Range in New Mexico after being jammed. On that occasion, the air traffic controller called a stop buzzer. "[The] facility manager on duty later informed me we can't ask them to 'stop buzzer' and to just keep putting aircraft on headings," their ASRS report reads. Putting an aircraft on headings requires giving pilots precise bearings to follow, rather than letting them perform their own navigation using GPS or other technologies. This adds work for controllers, who are already very busy at certain times of day...

The Pentagon uses its more remote military bases, many in the American West, to test how its forces operate under GPS denial. A Spectrum investigation earlier this year discovered that such jamming tests are far more prevalent than had previously been thought, possibly affecting thousands of civilian flights each year.

NASA has a launch date for that most Hollywood of missions, the Double Asteroid Redirection Test, which is basically a dry run of the movie "Armageddon." From a report: Unlike the film, this will not involve nukes, oil rigs or Aerosmith, but instead is a practical test of our ability to change the trajectory of an asteroid in a significant and predictable way. The DART mission, managed by the Planetary Defense Coordination Office (!), involves sending a pair of satellites out to a relatively nearby pair of asteroids, known as the Didymos binary. It's one large-ish asteroid, approximately 780 meters across -- that's Didymos proper -- and a 160-meter "moonlet" in its orbit.

A spacecraft bound for the planet Mercury will take a first look at the target tonight, when it makes its first-ever flyby of the small rocky world during an incredibly close encounter tonight. Space.com reports: The mission, called BepiColombo, is a joint project of the European Space Agency (ESA) and the Japanese Aerospace Exploration Agency (JAXA). It is only the second mission in history sent to orbit Mercury, the smallest and innermost planet of the solar system. BepiColombo's flyby tonight (Oct. 1) will bring the spacecraft within just 124 miles (200 kilometers) of the surface of Mercury, the closest the probe will ever get to the planet during its mission. The first images from the encounter are expected to reach Earth early Saturday (Oct. 2) and will be the first close images of Mercury's scorched surface since the end of NASA's Messenger orbiter mission in 2015.

BepiColombo will make its closest approach to Mercury at 7:34 p.m. EDT (2334 GMT) today (Oct.1), ESA said in a statement. The spacecraft will then continue on its winding trajectory around the sun. This close pass is one of nine gravity-assist flybys, maneuvers that use the gravity of celestial bodies to adjust a spacecraft's trajectory, that BepiColombo needs to perform before it can enter its target orbit around the planet. This flyby, however, will take the spacecraft even closer to the scorched planet's surface, than its ultimate scientific orbit of 300 to 930 miles (480 to 1,500 kilometers). The $750 million BepiColombo mission will be able to make measurements of the environment around the planet and take images with its black and white 'selfie' cameras, which provide a 1024 by 1024 pixel resolution (comparable to an early-2000s flip phone.) [...] After tonight's close pass, it will take four more flybys of Mercury by BepiColombo before the spacecraft is in the correct position to finally enter the planet's orbit, which is set to happen in 2025.

Jeff Bezos' Blue Origin "gambled" with its Moon lander proposal last year by hoping NASA would be willing to negotiate its $5.9 billion price tag, agency attorneys argued in blunt legal filings obtained by The Verge. From a report: NASA, cash-strapped with a tight budget from Congress, declined to negotiate and turned down Blue Origin's lunar lander in April and picked SpaceX's instead, sparking ongoing protests from Bezos' space company. NASA officials haven't talked much about Blue Origin's legal quarrels beyond occasional acknowledgements that the company's protesting -- first at a watchdog agency and now in federal court -- is holding up the agency's effort to land humans on the Moon by 2024.

But in hundreds of pages of legal filings The Verge obtained in a Freedom of Information Act request, agency attorneys exhaustively laid out NASA's defense of its Artemis Moon program and doubled down on its decision to pick one company, SpaceX, for the first crewed mission to the lunar surface since 1972. In NASA's main response to Blue Origin's protest, filed in late May, senior agency attorneys accused the company of employing a sort of door-in-the-face bidding tactic with its $5.9 billion proposal for Blue Moon, the lunar lander Blue Origin is building with a "National Team" that includes Lockheed Martin and Northrop Grumman. Blue Origin was "able and willing" to offer NASA a lower price for its lunar lander but chose not to because it expected NASA to ask and negotiate for a lower price first, the attorneys allege, citing a six-page declaration written by the company's senior vice president Brent Sherwood in April.

Paul Ratner writes via Interesting Engineering: Theoretical inventions known as the "UFO patents" have been inflaming worldwide curiosity. A product of the American engineer Dr. Salvatore Cezar Pais, the patents were filed during his work for the U.S. Navy and are so ambitious in their scope and imagination that they continue to draw interest despite any clear evidence that they are feasible. The patents include designs for a futuristic hybrid vehicle with a radical propulsion system that would work equally well in the air, underwater, and in space, as well as a compact fusion reactor, a gravitational wave generator, and even a "spacetime modification weapon." The technology involved could impact reality itself, claims its inventor, whose maverick audacity rivals that of Nikola Tesla.

How real are these ideas? While you can read the patents for yourself, it's evident that the tech necessary to actually create the devices described is beyond our current capabilities. Yet research into many of these fields has gone on for years, which may explain why the Navy expressed an interest. Another likely influence is the fact that the Chinese government seems to be working to develop similar technology. The fantastical inventions devised by Dr. Pais largely build upon an idea that he calls "The Pais Effect." In his patent write-ups and in an interview with The Drive, he described it as "the generation of extremely high electromagnetic energy fluxes (and hence high local energy densities) generated by controlled motion of electrically charged matter (from solid to plasma states) subjected to accelerated vibration and/or accelerated spin, via rapid acceleration transients." This effect amounts to the ability to spin electromagnetic fields to contain a fusion reaction. The electromagnetic energy fields would be so powerful that they could "engineer the fabric of our reality at the most fundamental level," writes Pais. In practical terms, this invention could lead to a veritable revolution in propulsion, quantum communications, and create an abundance of cheaply-produced energy. Certainly, an extraordinary claim that requires extraordinary evidence, as posits the Sagan standard.

Despite the well-founded unease at Dr. Pais's inventions, the Navy took them seriously enough to run experiments for three years and even found some of them "operable," although the extent of that alleged operability is under debate. In the patent documents, two Navy officials seemed to assert the operability of the inventions. Furthermore, in correspondence with The Drive's "War Zone," Timothy Boulay of NAWCAD, stated that Pais's High Energy Electromagnetic Field Generator was, in fact, tested from 2016 until 2019, at a cost of $508,000. The team working on the project consisted of at least 10 technicians and engineers and put in some 1,600 hours of work. But upon the conclusion of the testing, the Pais Effect "could not be proven," shared Boulay. What happened subsequently with the tested device and further investigations is not known at this point. There are indications in documents obtained by The Drive's WarZone through the Freedom of Information Act that the inventions could be moved to another research department in the Navy or the Air Force, or possibly even to NASA or DARPA, but whether that really happened is not clear. "One of the most attention-grabbing designs by Dr. Pais is the 2018 patent for a cone-shaped craft of unprecedented range and speed," writes Ratner. "Another futuristic patent with far-reaching ramifications is Pais' Plasma Compression Fusion Device. [...] Notes from researchers who worked on vetting Pais' ideas indicate that a possible outcome of the plasma fusion device and the high energy levels it may generate is the 'Spacetime Modification Weapon' (SMW). Research documents refer to it as 'a weapon that can make the Hydrogen bomb seem more like a firecracker, in comparison.'"

Pais also has a patent for an electromagnetic field generator, which could create "an impenetrable defensive shield to sea and land as well as space-based military and civilian assets." Another device conceived by Pais that could deflect asteroids is the high-frequency gravitational wave generator.

ytene writes: As reported by CNBC, the US Court of Federal Claims has released a redacted version of the lawsuit, filed by Jeff Bezos' Blue Origin, in a complaint against NASA. Earlier this year, the agency had awarded a $2.9 billion contract to SpaceX for the design and development of a lunar lander.

Although NASA has a long history of awarding contracts to promote innovation and competition, the Blue Origin suit seemed a little unusual given the company's current lack of launch experience (they have completed numerous successful tests, including a high-altitude "edge of space" flight for Bezos, his brother and guests, but have yet to place any vehicle in orbit, let alone establish a credible, commercial space flight presence).

As was also reported by CNBC, the Government Accountability Office conducted an investigation in to the initial Blue Origin complaint, after NASA suspended the process, but found no evidence that NASA awarded the contract incorrectly and denied the initial Blue Origin complaint.

The National Aeronautics and Space Administration plans to retire the International Space Station by the end of this decade, so the U.S. space agency is turning to private companies to build new space stations in orbit -- and expects to save more than $1 billion annually as a result. CNBC reports: NASA earlier this year unveiled the Commercial LEO Destinations project, with plans to award up to $400 million in total contracts to as many as four companies to begin development on private space stations. In response to NASA's request, director of commercial spaceflight Phil McAlister told CNBC that the agency "received roughly about a dozen proposals" from a variety of companies for contracts under the project. "We got an incredibly strong response from industry to our announcement for proposals for commercial, free fliers that go directly to orbit," McAlister said. "I can't remember the last time we got that many proposals [in response] to a [human spaceflight] contract announcement."

The ISS is more than 20 years old and costs NASA about $4 billion a year to operate. The space station is approved to operate through the end of 2024, with a likely lifespan extension to the end of 2028. But, moving forward, McAlister says that NASA wants "to be just one of many users instead of the primary sponsor and infrastructure supporter" for stations in low Earth orbit. "This strong industry response shows that our plan to retire the International Space Station in the latter part of this decade and transition to commercial space destinations is a viable, strong plan," McAlister said. "We are making tangible progress on developing commercial space destinations where people can work, play, and live," McAlister added. NASA is now evaluating the proposals, and McAlister said the agency hopes to announce the contract winners "before the end of the year," although he is "pushing for earlier." NASA "will not need anything near as big and as capable" as the ISS moving forward, said McAlister. He said the private space stations "could be very large, but NASA will only be paying for the part that we need."

"SpaceX safely returned its Crew Dragon spacecraft from orbit on Saturday, with the capsule carrying the four members of the Inspiration4 mission back to Earth after three days in space..." reports CNBC: "Thanks so much SpaceX, that was a heck of a ride for us and we're just getting started!" Inspiration4 commander Jared Isaacman said from the capsule after touching down.

Elon Musk tweeted his congratulations to the crew shortly after splashdown.

The historic private mission — which includes Isaacman, pilot Sian Proctor, medical officer Hayley Arceneaux and mission specialist Chris Sembroski — orbited the Earth at an altitude as high as 590 kilometers, which is above the International Space Station and the furthest humans have traveled above the surface in years. A free-flying spaceflight, the capsule did not dock with the ISS but instead circled the Earth independently at a rate of 15 orbits per day.

Inspiration4 shared photos from the crew's time in orbit, giving a look at the expansive views from the spacecraft's "cupola" window.

This is the third time SpaceX has returned astronauts from space, and the second time for this capsule — which previously flew the Crew-1 mission for NASA on a trip that returned in May.
