If all goes as planned, a SpaceX Falcon 9 rocket carrying the Double Asteroid Redirection Test (DART) will launch early Wednesday morning "to test whether slamming a spacecraft into an asteroid can nudge it into a different trajectory," reports The New York Times. "Results from the test, if successful, will come in handy if NASA and other space agencies ever need to deflect an asteroid to save Earth and avert a catastrophic impact." From the report: The DART spacecraft is scheduled to lift off atop a SpaceX Falcon 9 rocket on Wednesday at 1:20 a.m. Eastern time (or 10:20 p.m. local time) from the Vandenberg Space Force Base in California. NASA plans to host a livestream of the launch on its YouTube channel starting at 12:30 a.m. on Wednesday. If bad weather around the Vandenberg launch site prompts a delay, the next opportunity for liftoff would be about 24 hours later.

After launching to space, the spacecraft will make nearly one full orbit around the sun before it crosses paths with Dimorphos, a football-field-size asteroid that closely orbits a bigger asteroid, called Didymos, every 11 hours and 55 minutes. Astronomers call those two asteroids a binary system, where one is a mini-moon to the other. Together, the two asteroids make one full orbit around the sun every two years. Dimorphos poses no threat to Earth, and the mission is essentially target practice. DART's impact will happen in late September or early October next year, when the binary asteroids are at their closest point to Earth, roughly 6.8 million miles away.

Four hours before impact, the DART spacecraft, formally called a kinetic impactor, will autonomously steer itself straight toward Dimorphos for a head-on collision at 15,000 miles per hour. An onboard camera will capture and send back photos to Earth in real time until 20 seconds before impact. A tiny satellite from the Italian Space Agency, deployed 10 days before the impact, will come as close as 34 miles from the asteroid to snap images every six seconds in the moments before and after DART's impact.

An anonymous reader quotes a report from Phys.org: NASA and the nation's top federal nuclear research lab on Friday put out a request for proposals for a fission surface power system. NASA is collaborating with the U.S. Department of Energy's Idaho National Laboratory to establish a sun-independent power source for missions to the moon by the end of the decade. If successful in supporting a sustained human presence on the moon, the next objective would be Mars. NASA says fission surface power could provide sustained, abundant power no matter the environmental conditions on the moon or Mars. The reactor would be built on Earth and then sent to the moon.

Submitted plans for the fission surface power system should include a uranium-fueled reactor core, a system to convert the nuclear power into usable energy, a thermal management system to keep the reactor cool, and a distribution system providing no less than 40 kilowatts of continuous electric power for 10 years in the lunar environment. Some other requirements include that it be capable of turning itself off and on without human help, that it be able to operate from the deck of a lunar lander, and that it can be removed from the lander and run on a mobile system and be transported to a different lunar site for operation. Additionally, when launched from Earth to the moon, it should fit inside a 12-foot (4-meter) diameter cylinder that's 18 feet (6 meters) long. It should not weigh more than 13,200 pounds (6,000 kilograms). The proposal requests are for an initial system design and must be submitted by Feb. 19.

An anonymous reader quotes a report from CNBC: Elon Musk on Wednesday said SpaceX is "hoping" to launch the first orbital flight test of its mammoth Starship rocket in January, a schedule that depends on testing and regulatory approval. "We'll do a bunch of tests in December and hopefully launch in January," Musk said, speaking at a meeting of the National Academies of Sciences, Engineering, and Medicine Space Studies Board.

The company's next major step in developing Starship is launching to orbit. First, the company needs a launch license from the Federal Aviation Administration for the mission, with the regulator expecting to complete a key environmental assessment by the end of this year. Musk noted that he wasn't sure if Starship would successfully reach orbit on the first try, but emphasized that he is "confident" that the rocket will get to space in 2022. "We intend to have a high flight rate next year," Musk said.

SpaceX aims to launch as many as a dozen Starship test flights next year, he said, to complete the "test flight program" and move to launching "real payloads in 2023." He stressed that creating a mass production line for Starship is crucial to the program's long-term goals, noting that the current "biggest constraint" on rocket manufacturing is how fast the company can build the Raptor engines needed for Starship. "I think, in order for life to become multiplanetary, we'll need maybe 1,000 ships or something like that," Musk said. "The overarching goal of SpaceX has been to advance space technology such that humanity can become a multi-planet species and, ultimately, a spacefaring civilization." SpaceX received a $2.9 billion contract from NASA to develop Starship for delivering astronauts to the moon's surface, but Musk said the company is "not assuming any international collaboration" or external funding for the rocket program. "[Starship] is at least 90% internally funded thus far," Musk said.

"NASA is not properly estimating costs for the Artemis program and could spend $93 billion between fiscal years 2021 and 2025," writes Slashdot reader schwit1. "NASA recently extended its target date for sending astronauts back to the moon to 2025 at the earliest." But, according to a new report (PDF) from NASA's Office of the Inspector General, it could be several years after 2024. The Verge reports: The recent prediction comes from NASA's Office of the Inspector General, which does periodic audits of the space agency's various programs. In its latest report, the OIG took a comprehensive look at NASA's Artemis program, the agency's ambitious initiative to send people back to the Moon, as well as land the first woman and the first person of color on the lunar surface. [...] NASA's Artemis program relies on a suite of complicated vehicles all working together to get astronauts safely to the Moon, including a massive new rocket called the Space Launch System, or SLS, that will send people to deep space inside a new crew capsule called Orion. Meanwhile, SpaceX is developing its next-generation spacecraft, called Starship, to carry people to and from the lunar surface for NASA -- part of a $2.9 billion contract awarded to the company in April.

However, Starship is still in very early stages of development and has yet to launch to orbit. SLS and Orion also have not flown on their first flight together. The OIG report, released Monday, highlights these issues and reveals just how much work is left to be done on Artemis, making a 2024 landing date unrealistic. "Given the time needed to develop and fully test the HLS and new spacesuits, we project NASA will exceed its current timetable for landing humans on the Moon in late 2024 by several years," the report states. [...] Rival space company Blue Origin had also hoped to receive a contract from NASA to develop a lunar lander, but when the space agency gave the award to SpaceX, the company sued in federal court. The lawsuit prevented NASA and SpaceX from working together on the lander until the litigation was resolved.

The OIG report notes that the lawsuit did have an impact on the overall schedule, but the office also argues that the development schedule for SpaceX's Starship is overly optimistic. SpaceX CEO Elon Musk continues to make bold predictions for Starship's first major test launch, claiming multiple times it'd be ready to fly to orbit for the first time this year. However, the OIG report estimates the first orbital flight test of Starship will occur sometime in the second quarter of 2022. The document does argue that SpaceX may be able to shave off some time due to its speedy testing pace compared with earlier NASA spaceflight programs. But there is still quite a lot of work to be done after Starship's orbital flight test. [...] The OIG report predicts that the debut of NASA's SLS rocket and Orion combo will also be delayed.

Scientists have identified what appears to be a small chunk of the moon that is tracking the Earth's orbit around the Sun. From a report: The asteroid, named Kamo'oalewa, was discovered in 2016 but until now relatively little has been known about it. New observations suggest it could be a fragment from the moon that was thrown into space by an ancient lunar collision. Kamo'oalewa is one of Earth's quasi-satellites, a category of asteroid that orbits the Sun, but remains relatively close to the planet -- in this case about 9m miles away.

Despite being close in astronomical terms, the asteroid is about the size of a ferris wheel and about 4m times fainter than the faintest star that can be seen with the naked eye. Consequently, the Earth's most powerful telescopes are needed to make observations. Using the Large Binocular Telescope on Mount Graham in southern Arizona, astronomers found the spectrum of reflected light from Kamo'oalewa closely matched lunar rocks from Nasa's Apollo missions, suggesting it originated from the moon. They had initially compared the light with that reflected off other near-Earth asteroids, but drawn a blank. "I looked through every near-Earth asteroid spectrum we had access to, and nothing matched," said Ben Sharkey, a PhD student at the University of Arizona and the paper's lead author.

"Another space agency, about one-tenth the size of NASA, is thinking outside of the planet-sized box in its search for Martian life," reports CNET: With its Martian Moons Exploration mission (or MMX), the Japan Aerospace Exploration Agency, or JAXA, later this decade will touch down on a world no spacecraft has visited before: Phobos, one of Mars' mystifying moons. Scientists at JAXA, and other astronomers, hypothesize that on this curious moon they may find signs of ancient microbes that were catapulted off the surface of Mars and flung across the cosmos. The remains of these unwitting spacefaring organisms have been untouched for millions of years and, soon, could be plucked from Phobos' face and returned to Earth.

When an asteroid collides with a planet, the planet unleashes a mighty sneeze of dust and rock. The faster the asteroid smashes into the surface, the bigger the sneeze... [I]f the asteroid impact is powerful enough, the sneeze will fling dust and rock into space... Just like a human sneeze contains microbes, the material ejected by a planet may also contain microscopic life — or the remnants of it. If the asteroid death blast doesn't melt the rock and the microbes to mere atoms, there's a chance they can float into the cosmos... Mars is scarred by impacts from drifter asteroids that slammed into the surface over the planet's life. If these impacts were to hit in just the right spot, at just the right angle and just the right time, there's a chance the ejected material would make it to Phobos, Mars' curious, potato-shaped moon. Phobos has the closest orbit of any known moon to its parent body, circling the red planet at a distance of just 6,000 kilometers (3,700 miles), about the same as the distance between Tokyo and Honolulu....

Phobos is practically hugging Mars, and moves around the planet so quickly that if you were to observe it from the surface, you'd be able to see it rise and set twice every Martian day. Its proximity to the red planet has led JAXA scientists and engineers to speculate about the potential for finding the remnants of Martian microbes on the moon's surface. "If Martian life once existed and was widespread elsewhere on Mars, the chance that its dead remains exist also on Phobos is, in my opinion, relatively high," says Ryuki Hyodo, a planetary scientist at JAXA's Institute of Space and Astronautical Science... It's possible, JAXA believes, that Phobos could be a satellite cemetery, unwittingly holding molecular evidence of long-dead microorganisms....

With a planned sample return date of 2029, MMX would be the first time samples have been returned from the Martian sphere. While the space agency estimates just 0.1% of Phobos' soil likely originated on Mars, there's a chance MMX could bring back the first samples of the red planet to Earth.

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.

Thelasko shares a report from Ars Technica, written by Peter Opaskar: Frank Herbert's 1965 sci-fi novel Dune gets a new film adaptation -- this one helmed by Denis Villeneuve (Arrival, Blade Runner 2049) -- later this month. But before Ars Technica reviews the movie, there's the matter of its predecessor: 1984's Dune, made by a then up-and-coming filmmaker named David Lynch. Detractors call Lynch's saga -- a tale of two noble space families 8,000 years in the future, fighting over the most valuable resource in the universe amidst sandworms the size of aircraft carriers -- incomprehensible, stilted, and ridiculous. It lost piles of money. Yet fans, especially in recent years, have reclaimed Lynch's film as a magnificent folly, a work of holy, glorious madness.

So which group am I in? Both. Am I about to describe Dune as "so bad it's good"? No, that's a loser take for cowards. I once half-heard a radio interview with someone speculating that the then-current artistic moment was not "so bad it's good," and it wasn't "ironic" either -- it was actually "awesome." (I didn't catch who he was, so if any of this sounds familiar, hit me up in the comments.) Art can speak to you while at the same time being absurd. The relatable can sometimes be reached only by going through the ridiculous. The two can be inseparable, like the gravitational pull between a gas giant and its moon -- or Riggs and Murtaugh.

The example the radio interviewee gave was of Evel Knievel, the '70s daredevil who wore a cape and jumped dirt bikes over rows of buses. Absurd? Heavens, yes. A feat of motorcycling and physicality? Absolutely. But beyond that, we can relate to Knievel's need to achieve transcendence at such a, shall we say, niche skill. We might also marvel at our own ability to be impressed by something that should be objectively useless but is instead actually awesome. A more contemporary example might be Tenet. It's a relentless international thriller about fate and climate change and the need for good people to hold evil at bay. But it's also a "dudes rock!" bromance between Two Cool Guys in Suits spouting sci-fi mumbo-jumbo. It can't be one without the other. "I have faith in Denis Villeneuve and his new version of Dune starring Timothee Chalamet," says Opaskar. "But it will probably be a normal movie for normal people, in which characters with recognizable emotions talk in a recognizable way and move through a plot we understand to achieve clearly defined goals. Which is all fine and good, but how likely is it to inspire sick beats for '90s kids doing ecstasy?"

"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.

"China launched a three-person crew into space in the early hours of Saturday," reports CNN, calling it "a major step for the country's young space program, which is rapidly becoming one of the world's most advanced..." They will dock at China's new space station, Tiangong (which means Heavenly Palace), six and a half hours after launch. They will live and work at the station for 183 days, or just about six months... "This will certainly be their longest mission, which is quite impressive when you consider how early it is in their human spaceflight regimen," said Dean Cheng, senior research fellow at the Davis Institute for National Security and Foreign Policy.

This is the second crewed mission during the construction of the space station, which China plans to have fully crewed and operational by December 2022. The first crewed mission, a three-month stay by three other astronauts, was completed last month. Six more missions have been scheduled before the end of next year, including two crewed missions, two laboratory modules and two cargo missions. "For the Chinese, this is still early in their human spaceflight effort as they've been doing this for less than 20 years ... and for fewer than 10 missions," Cheng added. "In the past, the Chinese put up a crewed flight only once every two to three years. Now, they're sending them up every few months."

"If the Chinese maintain this pace ... it reflects a major shift in the mission tempo for their human spaceflight efforts...."

China successfully landed an exploratory rover on the moon last December and one on Mars in May. The first module of the Tiangong space station launched in April. Just last week, an international team of scientists released their findings from the moon rocks China brought back to Earth... "The European Space Agency, Russia, India, and Israel have suffered Moon or Mars probe failures in recent years; China succeeded with both on the first tries," David Burbach, associate professor of national security affairs at the US Naval War College, told CNN via email. Though the US still has the world's leading space program, he said, "there's no doubt that China is the world's Number 2 space power today."

China's ambitions span years into the future, with grand plans for space exploration, research and commercialization. One of the biggest ventures will be building a joint China-Russia research station on the moon's south pole by 2035 — a facility that will be open to international participation... Chinese astronauts have long been locked out of the International Space Station due to US political objections and legislative restrictions — which is why it has been a long-standing goal of China's to build a station of its own...

One reason space research cannot be divorced from terrestrial politics, and why the issue is so complicated, is because "the Chinese space program is heavily influenced, and its human and lunar programs are overseen, by the Chinese military," Cheng said. "Cooperating with China in space means cooperating with the Chinese military."

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."

Earth is losing some of its glow, a study published in Geophysical Research Letters last week shows. It appears climate change and a natural climate shift have essentially scuffed up our planet. From a report: The study takes a look at earthshine, or the light reflected from the planet that casts a faint light on the surface of the Moon. It's also known as the Da Vinci Glow, because Leonardo da Vinci was the first person to formally write about it. Research has advanced quite a bit since da Vinci's writing 500 years ago, and the new findings use two decades of earthshine data collected at Big Bear Solar Observatory using a special type of telescope to view the Moon. The best time to observe earthshine is when the Moon is waxing or waning. Look at the Moon then, and you may be able to make out a faint outline of the whole Moon in addition to the sliver brightly illuminated by the Sun. That ghostly outline is thanks to earthshine, caused by the sunlight reflecting off our planet.

The observatory is perfectly situated to measure earthshine for 40% of the planet, spanning the Pacific and parts of North America. Analyzing the data for roughly 800 nights between 1998 and 2017 showed a small but significant decline in earthshine. There were some year-to-year shifts, but the paper notes that those are "quite muted, with a long-term decline dominating the time series." The scientists used satellite data to gauge what drove the dimming. Land, ice, clouds, and open ocean all have different levels of reflectivity that contribute to earthshine. (The reflectivity of different surfaces is also referred to as albedo.) The findings point to the disappearance of clouds in the tropical Pacific as the culprit in dulling Earth's shine. "The albedo drop was such a surprise to us when we analyzed the last three years of data after 17 years of nearly flat albedo," said Philip Goode, a researcher at New Jersey Institute of Technology and the lead author of the report, in a statement.

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.

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.

Scientists found evidence that a region of northern Mars called Arabia Terra experienced thousands of "super eruptions," the biggest volcanic eruptions known, over a 500-million-year period. NASA reports the findings in a post: Some volcanoes can produce eruptions so powerful they release oceans of dust and toxic gases into the air, blocking out sunlight and changing a planet's climate for decades. By studying the topography and mineral composition of a portion of the Arabia Terra region in northern Mars, scientists recently found evidence for thousands of such eruptions, or "super eruptions," which are the most violent volcanic explosions known. Spewing water vapor, carbon dioxide, and sulfur dioxide into the air, these explosions tore through the Martian surface over a 500-million-year period about 4 billion years ago. Scientists reported this estimate in a paper published in the journal Geophysical Research Letters in July 2021. "Each one of these eruptions would have had a significant climate impact -- maybe the released gas made the atmosphere thicker or blocked the Sun and made the atmosphere colder," said Patrick Whelley, a geologist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, who led the Arabia Terra analysis. "Modelers of the Martian climate will have some work to do to try to understand the impact of the volcanoes."
[...]
One remaining question is how a planet can have only one type of volcano littering a region. On Earth volcanoes capable of super eruptions -- the most recent erupted 76,000 years ago in Sumatra, Indonesia -- are dispersed around the globe and exist in the same areas as other volcano types. Mars, too, has many other types of volcanoes, including the biggest volcano in the solar system called Olympus Mons. Olympus Mons is 100 times larger by volume than Earth's largest volcano of Mauna Loa in Hawaii, and is known as a "shield volcano," which drains lava down a gently sloping mountain. Arabia Terra so far has the only evidence of explosive volcanoes on Mars. It's possible that super-eruptive volcanoes were concentrated in regions on Earth but have been eroded physically and chemically or moved around the globe as continents shifted due to plate tectonics. These types of explosive volcanoes also could exist in regions of Jupiter's moon Io or could have been clustered on Venus. Whatever the case may be, Richardson hopes Arabia Terra will teach scientists something new about geological processes that help shape planets and moons.

Google and Apple will have to open their app stores to alternative payment systems in South Korea [Editor's note: the link may be paywalled; alternative source], threatening their lucrative commissions on digital sales. From a report: A bill passed Tuesday by South Korea's National Assembly is the first in the world to dent the tech giants' dominance over how apps on their platforms sell their digital goods. It will become law once signed by President Moon Jae-in, whose party strongly endorsed the legislation. The law amends South Korea's Telecommunications Business Act to prevent large app-market operators from requiring the use of their in-app purchasing systems. It also bans operators from unreasonably delaying the approval of apps or deleting them from the marketplace -- provisions meant to head off retaliation against app makers.

Companies that fail to comply could be fined up to 3% of their South Korea revenue by the Korea Communications Commission, the country's media regulator. The law will be referenced by regulators in other places -- such as the European Union and the U.S. -- that also are scrutinizing global tech companies, said Yoo Byung-joon, a professor of business at Seoul National University who researches digital commerce. "Korea's decision reflects a broader trend to step up regulation of technology-platform businesses, which have been criticized for having too much power," Mr. Yoo said.

Earlier this month Jeff Bezos' Blue Origin sued NASA over a moon lander contract awarded to SpaceX.

Now Mashable reports that "America's next trip to the moon may suddenly be delayed a bit thanks to...PDFs?" A U.S. federal judge has granted the Department of Justice a week-long extension in its lawsuit with Jeff Bezos' space company Blue Origin. The reason? Large PDF files...

According to the DOJ, there is more than 7 GB of data related to the case. However, the U.S. Court of Federal Claims' online system allows for only files of up to 50 MB in size to be uploaded. This all amounts to "several hundred" PDFs, including other file formats that would be converted to PDFs. The DOJ says it also sought to convert multiple separate documents into individual PDF batches but explained that those larger files could cause the upload system to crash. "We have tried several different ways to create 50-megabyte files for more efficient filing, all without success thus far," the DOJ said.

Instead of using the online file system, the U.S. government will transfer the documents for the case to DVDs.
Futurism reports the situation was exacerbated "because the agency staff that could have fixed the issue were at the 36th Annual Space Symposium last week."

On Twitter, space reporter Joey Roullete notes the judge's ruling means an additional one-week stay before the awarding of SpaceX's contract..

Or, as Mashable puts it, "Space exploration is currently on hold thanks to a lawsuit and a slew of pesky PDF files."

Eric Niiler writes via Wired: The landscape of Titan, Saturn's largest moon, is both familiar and strange. Like Earth, Titan has rivers, lakes, clouds, and falling raindrops, as well as mountains of ice and a thick atmosphere. But instead of water, Titan's chemical cycle is composed of liquid methane, an organic molecule made from one carbon and four hydrogen atoms. Researchers believe this swirling mixture of methane, combined with the moon's nitrogen-laden atmosphere, surface water ice, and maybe some energy from either a volcano or a meteor impact, might have been the perfect recipe to create some kind of simple life form. [...] Now, A researcher has recreated Titan's environment in a small glass cylinder and mixed organic chemicals under the same temperature and pressure conditions found on that moon. Organic molecules that are liquid on Earth -- such as methane and benzene -- become solid icy mineral crystals on Titan because it's so cold, sometimes down to -290 Fahrenheit, according to Tomce Runcevski, an assistant professor of chemistry at Southern Methodist University, and the principal investigator on a study presented this week at the American Chemical Society meeting.

In a series of experiments, Runcevski took tiny glass tubes, sucked the air out of them with a pump, and added water ice. Then, one at a time, he added nitrogen, methane, its chemical relative ethane, and other organic compounds. Each time, he varied the composition of the chemical mixture inside the glass cylinders to see what would happen. He next applied pressure -- equivalent to about 1.45 times Earth's atmosphere -- and reduced the temperature by surrounding the vials with extremely cold air. [...] Under that moon's atmospheric pressure and temperature, he found that two organic molecules abundant on Titan and toxic to humans here on Earth -- acetonitrile and propionitrile -- become a single crystalline form. On Titan, these two molecules are formed by the combination of nitrogen and methane, plus energy from the sun, Saturn's magnetic field, and cosmic rays. Acetonitrile and propionitrile start as a gas in the atmosphere, then condense into aerosols, and then rain down onto the moon's surface and become chunks of solid minerals in several forms.

It's the first time that these two chemicals have been combined into a crystal shape on Earth under the conditions present on Titan. Another important finding is that the outer facet of the crystal also has a slight electric charge, or polarity, on its surface. That surface charge can attract other molecules such as water -- which would be necessary to form the building blocks of carbon-based life. This new experiment doesn't prove that there's life on Titan, but it means that researchers can discover new things about its weird, frigid surface environment even before the NASA Dragonfly spacecraft lands there.

Jeff Bezos' space company Blue Origin brought its fight against NASA's Moon program to federal court on Monday, doubling down on accusations that the agency wrongly evaluated its lunar lander proposal. From a report: The complaint escalates a monthslong crusade by the company to win a chunk of lunar lander funds that was only given to its rival, Elon Musk's SpaceX and comes weeks after Blue Origin's first protest over the Moon program was squashed by a federal watchdog agency. Now in court, Blue Origin's challenge could add another pause to SpaceX's contract and a new lengthy delay to NASA's race to land astronauts on the Moon by 2024.

Blue Origin's complaint, filed with the US Court of Federal Claims, was shrouded behind a protective order. The company is broadly challenging NASA's decision to pick SpaceX for the lunar lander award, and "more specifically ... challenges NASA's unlawful and improper evaluation of proposals submitted under the HLS Option A BAA," according to its request to file its complaint under seal. Blue Origin was one of three firms vying for a contract to land NASA's first astronauts on the Moon since 1972. In April, NASA shelved the company's $5.9 billion proposal of its Blue Moon landing system and went with SpaceX's $2.9 billion Starship proposal instead, opting to pick just one company for the project after saying it might pick two. Limited funding from Congress only allowed one contract, NASA has argued.
