China's orbital outpost Tiangong was completed in 2022 and is hosting up to three astronauts at a time, reports CNN.

But meanwhile U.S. lawmakers are now signaling there's not time to develop and launch a replacement for the International Space Station — considered the signal most expensive object ever built — before its deorbiting in 2030. A recent Senate bill calls for the U.S. to continue funding it as late as 2032, but that bill still awaits approval from the U.S. Senate and the House.

But some private space companies are already building their alternatives: Private companies that are in the early design and mockup phase of developing these space stations are still waiting on NASA for guidance — and money... [NASA's "Requests for Proposals"] were delayed, in part because it took all of 2025 to cinch a confirmation for Trump's on-again-off-again pick for NASA administrator, Jared Isaacman [confirmed in December]... Similarly, 2025 saw a 45-day government shutdown, the longest in history — adding another hiccup in the space agency's plans to begin formally soliciting proposals from the private sector. Companies now expect that NASA will issue its Request for Proposals in late March or early April, one CEO told CNN...

Several commercial outfits have recently announced big funding influxes aimed at speeding up the development and launch of new orbiting outposts. Houston-based Axiom Space announced a $350 million funding round last month. Its California-based competitor Vast then notched a $500 million raise in early March. Vast is determined to launch a bare-bones station to orbit as soon as possible, with or without federal input, according to the company. "Our approach is to actually not wait for (NASA) and get going and build a minimum viable product, single-module space station called Haven-1, which we're launching into orbit next year," Vast CEO Max Haot told CNN in a phone interview earlier this month. Similarly, Axiom Space is working toward a 2028 launch date for a module that it plans to initially attach to the ISS before breaking off to orbit on its own. A spokesperson told CNN that it the company is "committed" to winning the NASA contract money and may continue pursing such goals even without contract awards.

Still, there's lingering doubt that any of the companies pursuing space stations will be able to stay afloat without securing a coveted NASA contract or at least cinching significant business from the public sector.
The article includes "Another complicating fact: Russia, the United States' primary partner on the ISS, has not pledged to keep operating its half of the space station past 2028." NASA will eventually evaluate proposals for an ISS alternative from Vast, Axiom Space, Jeff Bezos' Blue Origin, Max Space and several competitors including Voyager Technologies, CNN notes, ultimately handing out an estimated $1.5 billion in contracts between 2026 and 2031.

And while those companies may wait decades before a return on their investment, the article includes this quotes from the cofounder/general partner of Balerion Space Ventures, which led the fundraising for Vast. " What's obvious to us is you're going to have multiple vehicles with myriad companies go into space. You're going to have vehicles leaving from celestial bodies, like the moon. And we need a habitat."

NASA's Hubble Space Telescope unexpectedly captured a rare, early-stage breakup of comet C/2025 K1 (ATLAS) just days after it first began disintegrating. Phys.org reports: "Sometimes the best science happens by accident," said co-investigator John Noonan, a research professor in the Department of Physics at Auburn University in Alabama. "This comet got observed because our original comet was not viewable due to some new technical constraints after we won our proposal. We had to find a new target -- and right when we observed it, it happened to break apart, which is the slimmest of slim chances."

Noonan didn't know K1 was fragmenting until he viewed the images the day after Hubble took them. "While I was taking an initial look at the data, I saw that there were four comets in those images when we only proposed to look at one," said Noonan. "So we knew this was something really, really special." Hubble caught K1 fragmenting into at least four pieces, each with a distinct coma, the fuzzy envelope of gas and dust that surrounds a comet's icy nucleus. Hubble cleanly resolved the fragments, but to ground-based telescopes, at the time they only appeared as barely distinguishable, bright blobs. [...]

"Never before has Hubble caught a fragmenting comet this close to when it actually fell apart. Most of the time, it's a few weeks to a month later. And in this case, we were able to see it just days after," said Noonan. "This is telling us something very important about the physics of what's happening at the comet's surface. We may be seeing the timescale it takes to form a substantial dust layer that can then be ejected by the gas." The findings have been published in the journal Icarus.

sciencehabit shares a report from Science.org: In The Martian, fictional astronaut Mark Watney survives the wasteland of Mars by growing potatoes in lunar soil -- with a bit of help from human poop. The idea may not be so far-fetched. In a preprint posted this month on bioRxiv, researchers show potatoes can indeed grow in the equivalent of Moon dust, though they need a lot of help from compost found on Earth. To make the discovery, scientists first had to re-create lunar regolith -- the loose, powdery layer that blankets the Moon's surface. To replicate that in the lab, David Handy, a space biologist at Oregon State University (OSU), and his colleagues used a mix of crushed minerals and volcanic ash that matched the chemistry of the Moon.

But lunar regolith is entirely devoid of the organic matter that plants need to grow. "Turning an inorganic, inhospitable bucket of glorified sand into something that can support plant growth is complex," says Anna-Lisa Paul, a plant molecular biologist at the University of Florida not involved with the work. So Handy and his colleagues added vermicompost -- organic waste from worms -- into the regolith. They found that a mix with 5% compost allowed the potatoes to grow while still emulating the stressful conditions of the lunar environment. After almost 2 months of growth, the team harvested the tubers, freeze-dried them, and ground them up for further testing.

Analysis of the potatoes' DNA showed stress-related genes had been activated. The potatoes also had higher concentrations of copper and zinc than Earth-grown ones, which may make them dangerous for human consumption. The plants' nutritional value, though, was similar to traditional potatoes -- a surprise to the scientists, who expected lower levels of nutrition "because the plants might have been working overtime to overcome certain stressors," Handy says.

Nvidia unveiled its Vera Rubin Space-1 system for powering AI workloads in orbital data centers. "Space computing, the final frontier, has arrived," said CEO Jensen Huang. "As we deploy satellite constellations and explore deeper into space, intelligence must live wherever data is generated." CNBC reports: In a press release, the company said that its Vera Rubin Space-1 Module, which includes the IGX Thor and Jetson Orin, will be used on space missions led by multiple companies. The chips are specifically "engineered for size-, weight- and power-constrained environments." Partners include Axiom Space, Starcloud and Planet.

Huang said Nvidia is working with partners on a new computer for orbital data centers, but there are still engineering hurdles to overcome. "In space, there's no convection, there's just radiation," Huang said during his GTC keynote, "and so we have to figure out how to cool these systems out in space, but we've got lots of great engineers working on it."

"There are countless upgrades you could make to your gaming setup," writes PC Gamer's Jacob Ridley. "A wireless this, a bigger that, a faster thing. But how do you know what's going to be a genuine upgrade worth investing in? Personally, I think it might be split spacebars." His argument centers on the fact that spacebars take up a "greedy" amount of keyboard space -- space that could instead be divided into multiple keys for different actions, such as voice chat or melee attacks. From the report: While it's often very easy to reprogram your spacebar to do a different action via your keyboard's software, it's a lot harder to reprogram your brain to hit any other key when you try to jump in game. Spacebar makes you jump. Everyone knows that; it's practically etched onto your brain if you're a long-time mouse and keyboard player. So, why does a split spacebar help with that? It comes down to this: once you know which side of a spacebar you tend to thwack with your thumb, you can program the other side to do whatever you want. I hit the right-side of my spacebar every time when I'm typing. Therefore, when I started using a Wooting 60HE v2 with a split spacebar, I set the left-side to be the delete key; the keyboard lacking a dedicated delete key for its 60% size.

Though for gaming, the split spacebar offers much more varied purpose. People do strange things with the WASD keys that I won't litigate here, but I'm pretty sure most gamers use their left thumb to strike the spacebar for gaming. Right? Right. If you fall into this category, you have the option of using the right-side spacebar for things like a chunky melee key, or, my personal favorite, an in-game voice chat key.

An anonymous reader quotes a report from Bloomberg: Spending on data center projects in the U.S. has exploded, surpassing offices for the first time at the end of last year. It's a trend Matt Kunz saw early on when Meta built a computing hub outside Columbus, Ohio. Other tech companies soon swarmed into the area, drawn by its stable economy, university talent pipeline and ample power, water and land, said Kunz, vice president and general manager at Turner Construction Co., the firm that led Meta's build-out. Since Meta broke ground in 2017, it's expanded its data center campus, and Amazon.com Inc., Alphabet Inc.'s Google and Microsoft Corp. made plans to join it nearby.

"When one shows up, almost all the other ones tend to follow," Kunz said. For Turner, a construction giant responsible for supertall office skyscrapers, sports stadiums and cultural venues around the globe, data centers are commanding more of its bandwidth. The company completed $9.4 billion of the projects last year, more than five times its 2020 total. Last month, Turner announced it was chosen as one of the contractors on a $10 billion data center for Meta in Indiana. Tech companies' needs for AI processing facilities have made data centers the latest darling of the real estate industry. The properties are figuring heavily into portfolios of major investors such as Blackstone, Brookfield Asset Management and KKR, on a bet that long-term demand for computing power will continue to grow. At the same time, office development has slowed as cities across the U.S. contend with vacancies that have piled up since the Covid lockdowns.

Construction spending for data centers has climbed steadily in recent years, while outlays for general office projects headed downward, U.S. Census data show. The two crossed paths in December, with roughly $3.57 billion spent on data centers that month, compared with $3.49 billion for offices, according to preliminary estimates. The shift is likely to continue and "may perpetuate itself even further as AI is utilized for automating day-to-day jobs," said Andy Cvengros, co-lead of U.S. data center markets for the brokerage Jones Lang LaSalle Inc. "It's going to directly impact the amount of office space people need." According to Christopher McFadden, senior vice president at Turner, more than a third of the company's backlog is now tied to data centers.

"We're going to be building these at this scale for years to come," McFadden said. "There's a lot of wind in the sail."

sinij shares a report from Car and Driver: Honda is making a monumental shift in its business plans. The automaker is canceling the development and launch of the 0 Series SUV, the 0 Series saloon, and the Acura RSX, and as a result, expects to take a significant financial hit in 2026 [of up to $15.8 billion]. The automaker was blunt in its announcement of the changing plans, citing American tariff policies and the unpredictable nature surrounding American EV incentives and fossil fuel regulations. In its release marking the announcement, Honda made it clear that it expected to incur further financial losses over the long term if it went through with launching the cars.

Honda also called out changing customer values in China, with buyers focusing more on software features and less on things like fuel efficiency and cabin space. In its release regarding the changing product plans, Honda was shockingly blunt about its situation, saying that it was simply unable to deliver products that offer a better value than that of newer Chinese manufacturers.

Van Allen Probe A, a 1,300-pound (600 kg) NASA satellite launched in 2012 to study Earth's radiation belts, is expected to re-enter Earth's atmosphere this week. While most of it is expected to burn up during descent, "some components may survive," reports the BBC. "The space agency said there is a one in 4,200 chance of being harmed by a piece of the probe, which it characterized as 'low' risk." From the report: The spacecraft is projected to re-enter around 19:45 EST (00:45 GMT) on Tuesday the U.S. Space Force predicted, according to Nasa, though there is a 24-hour margin of "uncertainty" in the timing. [...] The spacecraft and its twin, Van Allen Probe B, were on a mission to gather unprecedented data on Earth's two permanent radiation belts. It was not immediately clear where in Earth's atmosphere the satellite is projected to re-enter. NASA and the U.S. Space Force has said it will monitor the re-entry and update any predictions. [...] Van Allen Probe B is not expected to re-enter the Earth's atmosphere before 2030.

A startup called Reflect Orbital wants to launch thousands of mirror-bearing satellites to reflect sunlight onto Earth at night and "power solar farms after sunset, provide lighting for rescue workers and illuminate city streets, among other things," reports the New York Times. From the report: It is an idea seemingly out of a sci-fi movie, but the company, Reflect Orbital of Hawthorne, Calif., could soon receive permission to launch its first prototype satellite with a 60-foot-wide mirror. The company has applied to the Federal Communications Commission, which issues the licenses needed to deploy satellites. If the F.C.C. approves, the test satellite could get a ride into orbit as soon as this summer. The F.C.C.'s public comment period on the application closes on Monday. "We're trying to build something that could replace fossil fuels and really power everything," Ben Nowack, Reflect Orbital's chief executive, said in an interview. The company has raised more than $28 million from investors.

[...] Reflect Orbital's first prototype, which will be roughly the size of a dorm fridge, is almost complete. Once in space, about 400 miles up, the test satellite would unfurl a square mirror nearly 60 feet wide. That would bounce sunlight to illuminate a circular patch about three miles wide on the Earth's surface. Someone looking up would see a dot in the sky about as bright as a full moon. Two more prototypes could follow within a year. By the end of 2028, Reflect Orbital hopes to launch 1,000 larger satellites, and 5,000 of them by 2030. The largest mirrors are planned to be nearly 180 feet wide, reflecting as much light as 100 full moons. The company said its goal was to deploy the full constellation of 50,000 satellites by 2035.

How much does it cost to order sunlight at night? Mr. Nowack said the company would charge about $5,000 an hour for the light of one mirror if a customer signed an annual contract for 1,000 hours or more. Lighting for one-time events and emergencies, which might require numerous satellites and more effort to coordinate, would be more expensive. For solar farms, he envisions splitting revenue from the electricity generated by the additional hours of light.

After decades of searching for extraterrestrial intelligence, the nonprofit SETI Foundation has an announcement. "A new study by researchers at the SETI Institute suggests stellar 'space weather' could make radio signals from extraterrestrial intelligence harder to detect." Stellar activity and plasma turbulence near a transmitting planet can broaden an otherwise ultra-narrow signal, spreading its power across more frequencies and making it more difficult to detect in traditional narrowband searches. For decades, many SETI experiments have focused on identifying spikes in frequency — signals unlikely to be produced by natural astrophysical processes. But the new research highlights an overlooked complication: even if an extraterrestrial transmitter produces a perfectly narrow signal, it may not remain narrow by the time it leaves its home system... "If a signal gets broadened by its own star's environment, it can slip below our detection thresholds, even if it's there, potentially helping explain some of the radio silence we've seen in technosignature searches," said Dr. Vishal Gajjar, Astronomer at the SETI Institute and lead author of the paper.
The researchers created "a practical framework for estimating how much broadening could occur for different types of stars" — and accounting for space weather — by "using radio transmissions from spacecraft in our own solar system, then extrapolated to other stellar environments."

The study's co-author (a SETI Institute research assistant) suggests this coud lead to better-targetted SETI searches. (M-dwarf stars — about 75% of stars in the Milky Way — actually have the highest likelihood that narrowband signals would get broadened before leaving their system...)

Colliding black holes were detected through spacetime ripples for the first time in 2015 by the Laser Interferometer Gravitational-Wave Observatory (LIGO), notes Space.com: Since then, LIGO and its partner gravitational wave detectors Virgo in Italy and KAGRA (Kamioka Gravitational Wave Detector) in Japan have detected a multitude of gravitational waves from colliding black holes, merging neutron stars, and even the odd "mixed merger" between a black hole and a neutron star... During the first three observing runs of LIGO, Virgo and KAGRA, scientists had only "heard" 90 potential gravitational wave sources.
But now they've published new data from the LIGO-Virgo-KAGRA (LVK) Collaboration that includes 128 more gravitatational wave sources — some incredibly distant: [Gravitational-Wave Transient Catalog-4.0, or GWTC-4] was collected during the fourth observational run of these gravitational wave detectors, which was conducted between May 2023 and Jan. 2024... Excitingly, GWTC-4 could technically have been even larger, as around 170 other gravitational wave detections made by LIGO, Virgo and KAGRA haven't yet made their way into the catalog.

One aspect of GWTC-4 that really stands out is the variety of events that created these signals. Within this catalog are gravitational waves from mergers between the heaviest black hole binaries yet, each about 130 times as massive as the sun, lopsided mergers between black holes with seriously mismatched masses, and black holes that are spinning at incredible speeds of around 40% the speed of light. In these cases, scientists think the extreme characteristics of the black holes involved in these mergers are the result of prior collisions, providing evidence of merger chains that explain how some black holes grow to masses billions of times that of the sun... GWTC-4 also includes two new mixed mergers involving black holes and neutron stars.

[LVK member Daniel Williams, of the University of Glasgow in the U.K., said in their statement] "We are really pushing the edges, and are seeing things that are more massive, spinning faster, and are more astrophysically interesting and unusual." The catalog also demonstrates just how sensitive the LVK detectors have become. Some of the neutron star mergers occurred up to 1 billion light-years away, while some of the black hole mergers occurred up to 10 billion light-years away.
Einstein's theory of general relativity can be tested with these detections, and "So far, the theory is passing all our tests," says LVK member Aaron Zimmerman, of the University of Texas at Austin. "But we're also learning that we have to make even more accurate predictions to keep up with all the data the universe is giving us." And LVK member Rachel Gray, a lecturer at the University of Glasgow, says "every merging black hole gives us a measurement of the Hubble constant, and by combining all of the gravitational wave sources together, we can vastly improve how accurate this measurement is."

In short, says LVK member Lucy Thomas of the California Institute of Technology (Caltech), "Each new gravitational-wave detection allows us to unlock another piece of the universe's puzzle in ways we couldn't just a decade ago."

Palantir's CEO was blunt. "If Silicon Valley believes we are going to take away everyone's white-collar job... and you're going to screw the military — if you don't think that's going to lead to the nationalization of our technology, you're retarded..."

And OpenAI's Sam Altman is thinking about the same thing, writes long-time Slashdot reader destinyland: "It has seemed to me for a long time it might be better if building AGI were a government project," Sam Altman publicly mused last week... Altman speculated on the possibility of the government "nationalizing" private AI companies into a public project, admitting more than once he's wondered what would happen next. "I obviously don't know," Altman said — but he added that "I have thought about it, of course" Altman's speculation hedged that "It doesn't seem super likely on the current trajectory. That said, I do think a close partnership between governments and the companies building this technology is super important."

Could powerful AI tools one day slip from the hands of private companies to be controlled by the U.S. government? Fortune magazine's AI editor points out that "many other breakthroughs with big strategic implications — from the Manhattan Project to the space race to early efforts to develop AI — were government-funded and largely government-directed." And Fortune added that last week the Defense Department threatened Anthropic with the Defense Production Act, which allows the president to designate "critical and strategic" goods for which businesses must accept the government's contracts. Fortune speculates this would've been "a sort of soft nationalization of Anthropic's production pipeline". Altman acknowledged Saturday that he'd felt the threat of attempted nationalization "behind a lot of the questions" he'd received when answering questions on X.com.

How exactly will this AI build-out be handled — and how should AI companies be working with the government? In a sprawling ask-me-anything session on X that included other members of OpenAI leadership, one Missouri-based developer even broached an AGI-government scenario directly with OpenAI's Head of National Security Partnerships, Katherine Mulligan. If OpenAI built an AGI — something that even passed its own Turing test for AGI — would that be a case where its government contracts compelled them to grant access to the Defense Department?

"No," Mulligan answered. At our current moment in time, "We control which models we deploy"
The article notes 100 OpenAI employees joined with 856 Google employees in an online letter titled "We Will Not Be Divided" urging their bosses to refuse their models' use in domestic mass surveillance and autonomously killing without human oversight.

But Adafruit's managing director Phillip Torrone (also long-time Slashdot reader ptorrone ) sees analogies to America's atomic bomb-building Manhattan Project, and "what happened when the scientists who built the thing tried to set conditions on how the thing would be used." (The government pressured them to back down, which he compares to the Pentagon's designating Anthropic a "supply chain risk" before offering OpenAI a contract "with the same red lines, just worded differently".)

Ironically, Anthropic CEO Dario Amodei frequently recommends the Pulitzer Prize-winning 1986 book The Making of the Atomic Bomb...

NASA heralded a new study published Friday documenting a first for humanity — "the first time a human-made object has measurably altered the path of a celestial body around the Sun."

It was 2022's DART mission where NASA crashed a spacecraft into an asteroid — and the experiment "could have implications for protecting Earth from future asteroid strikes," writes ScienceNews: A spacecraft slowed the orbit of a pair of asteroids around the sun by more than 10 micrometers per second... Within a month, researchers showed that the impact shortened Dimorphos' 12-hour orbit by 32 minutes. Some of the rocks knocked off of Dimorphos fled the vicinity completely, escaping the gravitational influence of the Dimorphos-Didymos pair, says planetary defense researcher Rahil Makadia of the University of Illinois Urbana-Champaign. Those rocky runaways took some momentum away from the duo and changed their joint motion around the sun.

To figure out how much that motion was affected, astronomers watched the asteroids pass in front of distant stars, dimming some of the stars' light like a tiny eclipse. These blinks, called stellar occultations, can be visible from anywhere on Earth and are predictable in advance... Calculating how far off occultation timings were from predictions revealed that the asteroids' orbit around the sun was about 150 milliseconds slower than before the DART impact...

Didymos and Dimorphos are not a threat to Earth, Makadia says, and weren't before DART. But knowing how a deliberate impact changes one asteroid's orbit can help make defense plans against another, "in case we need to do a kinetic impact for real."
The researchers spent nearly two and a half years to collect 22 measurements of the asteroid's post-crash position, relying on amateur astronomers "to go out into the middle of nowhere and observe the necessary stellar occultations," acvcording to their paper. Planetary defense researcher even tells ScienceNews "There was an observer who drove two days each way into the Australian outback to get these measurements."

Astronomers have spotted a galaxy they believe is made of 99.9% dark matter, reports CNN — and it's so faint, it's almost invisible: CDG-2, which is about 300 million light-years from Earth, appears to be so rich in dark matter that it could belong to a hypothesized subset of low surface brightness galaxies called "dark galaxies," which are believed to contain few or no stars.... [Post-doctoral astrophysics/statistics fellow Dayi Li at the University of Toronto was lead author on a study about the discovery, and tells CNN] There is no strict definition of dark galaxies... but their existence is predicted by dark matter theories and cosmological simulations. "Where exactly do we draw the line in terms of how many stars they should have is still ambiguous, because not everything in astronomy is as clear-cut as we like," he said. "To be technically correct, CDG-2 is an almost-dark galaxy. But the importance of CDG-2 is that it nudges us much closer to getting to that truly dark regime, while previously we did not think a galaxy this faint could exist."

To observe CDG-2, the researchers used data from three telescopes — Hubble, the European Space Agency's Euclid space observatory and the Subaru Telescope in Hawaii — along with a novel approach that involved looking for objects called globular clusters. "These are very tight, spherical groupings of very olds stars, basically the relics of the first generation of star formation," Li said. Globular clusters are bright even if the surrounding galaxy is not, and previous observations have shown a relationship between them and the presence of dark matter in a galaxy, Li added. Because CDG-2 appears to have very few stars, there must be something else providing the mass that the clusters need to hold themselves together. Li and his colleagues assume that the source of the mass is dark matter.

The researchers found a set of four globular clusters in the Perseus Cluster, a group of thousands of galaxies immersed in a cloud of gas and one of the most massive objects in the universe. Further observations revealed a glow or halo around the globular clusters, suggesting the presence of a galaxy... Astronomers believe, Li explained, that after the formation of the clusters early in the galaxy's existence, larger surrounding galaxies stripped it of the hydrogen gas required to make more individual stars like our sun. "The material that this galaxy needed to continue to form stars was no longer there, so it was left with basically just a dark matter halo and the four globular clusters." The process, he added, would leave behind a skeleton or ghost of "a galaxy that pretty much just failed." As a result of this formation mechanism, the galaxy only has 0.005% of the brightness of our own galaxy, Li said...

Studying potential dark galaxies is important because they provide nearly pristine views of the behavior of dark matter, according to Neal Dalal, a researcher at the Perimeter Institute for Theoretical Physics in Waterloo, Ontario, Canada, who was not involved with the study.
Robert Minchin, an astronomer at New Mexico's National Radio Astronomy Observatory, told CNN that "it seems likely that other very dark galaxies will be found by this method in the future."

"Reservation holders, it's finally time to get ready," writes long-time Slashdot reader AirHog. The EV news site Electrek reports: Aptera Motors, "the little startup that could," announced another important milestone... completing the first example of its flagship solar EV on its validation assembly line in Southern California...

While the validation line at its headquarters remains a low-volume assembly process, its successful operation represents the startup's transition from hand-built validation SEVs to a more structured assembly line process that will be fine-tuned for mass production... With low-volume assembly now being validated, Aptera is starting to publicly utter encouraging terms like "EPA certification" and, better yet, that holy grail of "initial customer deliveries." Before then, however, the Aptera Solar EVs built on this low-volume validation line will be used for testing programs such as thermal validation, brake performance, and "some destructive testing." Aptera shared that its assembly and integration team has grown to become the largest at the startup, "reflecting the beginning of its transition from engineering development to testing and production execution"...

As of March 2026, Aptera says it has over 50,000 reservations totaling over $2 billion in sales if all were to solidify following the launch of a deliverable vehicle.
Clean Technica notes the vehicles' "generous cargo space that comes out to 60% more storage than a Honda Accord and 20% more storage than a Prius, according to the company." "Built with recyclable materials, this eco-friendly vehicle features a lightweight carbon fiber structure and no-welding assembly for maximum cost and production efficiency," Aptera adds. The emphasis on lightweighting supports the goal of engineering a car that can travel on the electricity provided by its onboard solar panels.

The company currently advertises that the vehicle can travel 40 miles on solar power alone, with the battery providing extra juice as needed. Ideally, the car can keep recharging itself with sunlight, further elongating the time between charging sessions... [Its range is up to 1,000 miles with plug-in charging.] The new autocycle could also appeal to drivers who enjoy the challenge of hypermiling, which involves deploying a suite of driving techniques to minimize fuel consumption. Hypermiling can apply to gas-powered cars, but the magic really kicks in with the regenerative braking capability of EVs. Aptera's onboard solar panels add another dimension to the fun.

Ancient Slashdot reader alanw shares a report from the European Space Agency (ESA): Last year, an approximately 60 meter near-Earth object captured global attention. For a brief period, asteroid 2024 YR4 became the most dangerous asteroid discovered in the last 20 years. While an Earth impact was soon ruled out, the asteroid faded from view with a lingering 4% chance of striking the Moon on 22 December 2032. Now, that risk has been eliminated. Astronomers have confirmed that 2024 YR4 will not impact the Moon using new observations made by the Near-Infrared Camera (NIRCam) on the NASA/ESA/CSA James Webb Space Telescope. Instead, it will safely pass the Moon at a distance of more than 20 000 km.

A recently-revised Senate authorization bill (PDF), co-sponsored by Senate Commerce Committee Chair Ted Cruz, would extend the International Space Station's lifespan from 2030 to 2032 while pushing NASA to accelerate plans for commercial space stations to replace it. Ars Technica's Eric Berger reports: Regarding NASA's support for the development of commercial space stations, the bill mandates the following, within specified periods, of passage of the law:

- Within 60 days, publicly release the requirements for commercial space stations in low-Earth orbit
- Within 90 days, release the final "request for proposals" to solicit industry responses
- Within 180 days, enter into contracts with "two or more" commercial providers for such stations

Cruz is trying to inject urgency into NASA as several private companies -- including Axiom Space, Blue Origin, Vast, and Voyager -- are finalizing designs for space stations. All have expressed a desire for clarity from NASA on how long the space agency would like its astronauts to stay on board, the types of scientific equipment needed, and much more. These are known as "requirements" in NASA parlance.

[...] Cruz and other senators on the committee appear to share those concerns, as their legislation extends the International Space Station's lifespan from 2030 to 2032 (an extension must still be approved by international partners, including Russia). Moreover, the authorization bill states, "The Administrator shall not initiate the de-orbit of the ISS until the date on which a commercial low-Earth orbit destination has reached an initial operational capability." With this legislation, the U.S. Senate is making clear that it views a permanent human presence in low-Earth orbit as a high priority. This version of the authorization legislation must still be passed by the full Senate and work its way through the House of Representatives.

NASA is eyeing an April launch window for the upcoming Artemis II mission after it repaired a helium-flow issue on the Space Launch System upper stage rocket. "Work on the rocket and spacecraft will continue in the coming weeks as NASA prepares for rolling the rocket out to the launch pad again later this month ahead of a potential launch in April," NASA wrote in an update on Tuesday. Space.com reports: The repair work occurred inside the huge Vehicle Assembly Building (VAB) at NASA's Kennedy Space Center (KSC) in Florida. Artemis 2's SLS and Orion crew capsule have been in the VAB since Feb. 25, when they rolled back to the hangar from KSC's Launch Pad 39B. Just a few days earlier, the Artemis 2 stack successfully completed a wet dress rehearsal, a two-day-long practice run of the procedures leading up to launch.

In the wake of that test, however, NASA noticed an interruption in helium flow in the SLS' upper stage. That was a significant issue, because helium pressurizes the rocket's propellant tanks. Rollback was the only option, as the affected area in the upper stage was not accessible at the pad. The problem took a potential March launch out of play for Artemis 2, which will send four astronauts on a roughly 10-day flight around the moon. It will be the first crewed flight to the lunar neighborhood since Apollo 17 in 1972.

The next Artemis 2 launch window opens in April, with liftoff opportunities on April 1, April 3-6 and April 30. And those options apparently remain in play, thanks to recent work in the VAB. That work centered on a seal in an interface through which helium flows from ground equipment into the SLS upper stage. That seal was obstructing the interface, which is known as a quick disconnect.

Paramount Skydance plans to combine HBO Max and Paramount+ into a single streaming platform following its acquisition of Warner Bros. Discovery. "As we said, we do plan to put the two services together, which today gives us a little over 200 million direct-to-consumer subscribers," said David Ellison, the company's CEO. "We think that really positions us to compete with the leaders in the space." The deal still needs regulatory approval. The Washington Post reports: He added that Paramount didn't want to make changes to the HBO brand. "Our viewpoint is HBO should stay HBO," Ellison said, noting that his favorite HBO product is "Game of Thrones." If Justice Department regulators allow the deal to go through, it would place recent HBO Max hits, such as "The Pitt" and "A Knight of the Seven Kingdoms," alongside Paramount offerings including "South Park" and "Yellowstone." "They built a phenomenal brand," he said. "They are a leader in the space, and we just want them to continue doing more of it."

The deal to buy Warner Bros., valued at about $110 billion, will almost surely attract regulatory scrutiny from the Justice Department because -- without divestments -- it places major swaths of the film, television and news industries under one roof: Warner Bros. and Paramount studios, HBO Max and Paramount+, and CBS and CNN would all have the same parent company. Ellison expressed confidence on the call that the deal wouldn't face hurdles with regulators.

"At its peak in early 2014, Stack Overflow received more than 200,000 questions per month," notes the site DevClass.com. But in December they'd just 3,862 questions were asked — a 78 percent drop from the previous year.

But Stack Overflow's blog announced a beta of "a redesigned Stack Overflow" this week, noting that at July's WeAreDevelopers conference they'd "committed to pushing ourselves to experiment and evolve..." Over the past year, on the public platform, we introduced new features, including AI Assist, support for open-ended questions, enhancements to Chat, launched Coding Challenges, created an MCP server [granted limited access to AI agents and tools], expanded access to voting and comments, and more.

However, these launches are not standalone features. We have also been rethinking our look and feel, how people engage with Stack Overflow, and how content is created and shared. These new features, along with the redesign, represent how we are bringing Stack Overflow's new vision to life and delivering value that developers cannot find elsewhere.

Our goal is to build the space for every technical conversation, centered on real human-to-human connection and powered by AI when it helps most. To support this, we are introducing a redesigned Stack Overflow to best reflect this direction... During the beta period, users can visit the beta site at beta.stackoverflow.com and share feedback as we build towards a new experience on Stack Overflow.
They've updated their library of reusable UI components (buttons, forms, etc.), and are promising "More ways to share knowledge and ask any technical question." ("Alongside looking for the single right answer to your question, you can now find and share experience-based insights and peer recommendations...")

They're launching all the planned features and functionality in April, when "More users will automatically redirect to the new site." (Starting in April users "can continue to toggle back to the classic site for a limited time.")
