In December it looked like NASA's next administrator would be the billionaire businessman/space enthusiast who twice flew to orbit with SpaceX.

But Saturday the nomination was withdrawn "after a thorough review of prior associations," according to an announcement made on social media. The Guardian reports: His removal from consideration caught many in the space industry by surprise. Trump and the White House did not explain what led to the decision... In [Isaacman's] confirmation hearing in April, he sought to balance Nasa's existing moon-aligned space exploration strategy with pressure to shift the agency's focus on Mars, saying the US can plan for travel to both destinations. As a potential leader of Nasa's 18,000 employees, Isaacman faced a daunting task of implementing that decision to prioritize Mars, given that Nasa has spent years and billions of dollars trying to return its astronauts to the moon...

Some scientists saw the nominee change as further destabilizing to Nasa as it faces dramatic budget cuts without a confirmed leader in place to navigate political turbulence between Congress, the White House and the space agency's workforce.
"It was unclear whom the administration might tap to replace Isaacman," the article adds, though "One name being floated is the retired US air force Lt Gen Steven Kwast, an early advocate for the creation of the US Space Force..."

Ars Technica notes that Kwast, a former Lieutenant General in the U.S. Air Force, has a background that "seems to be far less oriented toward NASA's civil space mission and far more focused on seeing space as a battlefield — decidedly not an arena for cooperation and peaceful exploration."

"More than 200 climate and weather scientists from across the U.S. are taking part in a marathon livestream on YouTube," according to this report from Space.com. For 100 hours (that started Wednesday) they're sharing their scientific work and answering questions from viewers, "to prove the value of climate science," according to the article.

The event is being stated in protest of recent government funding cuts at NASA, the National Oceanic and Atmospheric Administration, the United States Geological Survey, and the National Science Foundation. (The event began with "scientists documenting their last few hours at NASA's Goddard Institute for Space Studies as the office was shuttered.") The marathon stream features mini-lectures, panels and question-and-answer sessions with hundreds of scientists, each speaking in their capacity as private citizens rather than on behalf of any institution. These include talks from former National Weather Service directors, Britney Schmidt, a groundbreaking glacier researcher, and legendary meteorologist John Morales.

In its first 30 hours, the stream got over 77,000 views.

Ultimately, the goal of the event is to give members of the public the chance to learn more about meteorology and climate science in an informal setting — and for free. "We really felt like the American public deserves to know what we do," Duffy said. However, many of the speakers and organizers also hope the transference of this knowledge will spur people to take action. The event's website features a link to 5 Calls, an organization that makes it easy for folks to contact their representatives in Congress about the importance of funding climate and weather research.

Astronomers have discovered a mysterious cosmic object, ASKAP J1832-0911, that emits both radio waves and X-rays in precise 44-minute cycles, making it unlike anything observed before. Space.com reports: This is the first time an object like this, a so-called "long-period transient" or "LPT," has been seen in high-energy X-ray light as well as low-energy radio wave light. The team behind this discovery hopes the finding could help reveal what these flashing objects actually are and how they launch their mystery signals. However, not only is there no explanation for how the signals from LPTs are generated yet, but astronomers also don't know why these signals "switch on" and "switch off" at long, regular and unusual intervals. "This object is unlike anything we have seen before," team leader and Curtin University researcher Zieng (Andy) Wang said in a statement. [...]

The team believes the true nature of ASKAP J1832-0911 is a dead star, they just don't quite know what form that star takes. A highly magnetic neutron star, or "magnetar," is one option, and a a white dwarf -- the kind of stellar remnant the sun will leave behind when it dies in over 5 billion years -- is another. "ASKAP J1831- 0911 could be a magnetar, the core of a dead star with powerful magnetic fields, or it could be a pair of stars in a binary system where one of the two is a highly magnetized white dwarf, a low-mass star at the end of its evolution," Wang said. "However, even those theories do not fully explain what we are observing. "This discovery could indicate a new type of physics or new models of stellar evolution." The research has been published in the journal Nature.

SpaceX's Starship Flight 9 successfully launched and reached space -- marking the first reuse of a Super Heavy booster -- but both rocket stages were ultimately lost mid-mission due to a "rapid unscheduled disassembly." SpaceX CEO Elon Musk said in a statement: "Starship made it to the scheduled ship engine cutoff, so big improvement over last flight! Leaks caused loss of main tank pressure during the coast and re-entry phase. Lot of good data to review." Musk said the next three Starship test launches could lift off every three to four weeks in the days ahead. Space.com reports: The mission lifted off from Starbase today at 7:37 p.m. EDT (2337 GMT; 6:37 p.m. local Texas time), sending the 40-story-tall rocket into the Texas sky atop a pillar of flame. It was a milestone launch, marking the first-ever reuse of a Super Heavy booster; this one earned its wings on Flight 7 in January. (SpaceX swapped out just four of its Raptors after that mission, meaning that 29 of the engines that flew today were flight-proven.) "Lessons learned from the first booster refurbishment and subsequent performance in flight will enable faster turnarounds of future reflights as progress is made towards vehicles requiring no hands-on maintenance between launches," the company wrote in a Flight 9 mission preview.

The Super Heavy had a somewhat different job to do today; it conducted a variety of experiments on its way back down to Earth. For example, the booster performed a controlled rather than randomized return flip and hit the atmosphere at a different angle. "By increasing the amount of atmospheric drag on the vehicle, a higher angle of attack can result in a lower descent speed, which in turn requires less propellant for the initial landing burn," SpaceX wrote in the mission preview. "Getting real-world data on how the booster is able to control its flight at this higher angle of attack will contribute to improved performance on future vehicles, including the next generation of Super Heavy." These experiments complicated Super Heavy's flight profile compared to previous missions, making another "chopsticks" catch at Starbase a tougher proposition. So, rather than risk damaging the launch tower and other infrastructure, SpaceX decided to bring the booster back for a "hard splashdown" in the Gulf of Mexico on Flight 9. That was the plan, anyway; Super Heavy didn't quite make it that far. The booster broke apart about 6 minutes and 20 seconds into today's flight, just after beginning its landing burn. "Confirmation that the booster did demise," [Dan Huot, of SpaceX's communications team] said during the Flight 9 webcast. Super Heavy's flight ended "before it was able to get through landing burn," he added.

Ship, by contrast, improved its performance a bit this time around. It reached space today on a suborbital trajectory that took it eastward over the Atlantic Ocean -- the same basic path the vehicle took on the truncated Flight 7 and Flight 8. But Flight 9 got choppy for Ship after that. The vehicle was supposed to deploy eight dummy versions of SpaceX's Starlink satellites about 18.5 minutes after liftoff, which would have been a landmark first for the Starship program. That didn't happen, however; the payload door couldn't open fully, so SpaceX abandoned the deployment try. Then, about 30 minutes after launch, Ship started to tumble, which was the result of a leak in Ship's fuel-tank systems, according to Huot. "A lot of those [tanks] are used for your attitude control," he said. "And so, at this point, we've essentially lost our attitude control with Starship." As a result, SpaceX nixed a plan to relight one of Ship's Raptor engines in space, a test that was supposed to happen about 38 minutes after launch. And the company gave up hope of a soft splashdown for the vehicle, instead becoming resigned to a breakup over the Indian Ocean during Ship's reentry.

The company therefore will not get all the data it wanted about Flight 9. And there was quite a bit to get; for example, SpaceX removed some of Ship's heat-shield tiles to stress-test vulnerable areas, and it also tried out several different tile materials, including one with an active cooling system. But the company plans to bounce back and try again soon, just as it did after Flight 7 and Flight 8. You can watch a recording of the launch on YouTube.

OnePlus is replacing its iconic Alert Slider with a new customizable "Plus Key" on the upcoming OnePlus 13s, which launches the new AI Plus Mind feature that lets users capture and search content found on screen. This update is part of a broader AI push for its devices that includes tools like AI VoiceScribe for call summaries, AI Translation for multi-modal language support, and AI Best Face 2.0 for photo corrections. Engadget reports: What AI Plus Mind does is save relevant content to a dedicated Mind Space, where users can browse various information that they've saved. Users can then search for the detail they want to find using natural language queries. Both the Plus Key and the AI Plus Mind will debut on the OnePlus 13s in Asia. AI Plus Mind will roll out to the rest of the OnePlus 13 Series devices through a future software update, while all future OnePlus phone will come with the new physical key. Notably, the new button and feature bear similarities to Nothing's physical Essential Key that can also save information inside the Essential Space app. Nothing was founded by Carl Pei who co-founded OnePlus.

"For decades, Hollywood directors including Stanley Kubrick, James Cameron and Alex Garland have cast AI as a villain that can turn into a killing machine," writes the Los Angeles Times. "Even Steven Spielberg's relatively hopeful A.I.: Artificial Intelligence had a pessimistic edge to its vision of the future."

But now "Google — a leading developer in AI technology — wants to move the cultural conversations away from the technology as seen in The Terminator, 2001: A Space Odyssey and Ex Machina.". So they're funding short films "that portray the technology in a less nightmarish light," produced by Range Media Partners (which represents many writers and actors) So far, two short films have been greenlit through the project: One, titled "Sweetwater," tells the story of a man who visits his childhood home and discovers a hologram of his dead celebrity mother. Michael Keaton will direct and appear in the film, which was written by his son, Sean Douglas. It is the first project they are working on together. The other, "Lucid," examines a couple who want to escape their suffocating reality and risk everything on a device that allows them to share the same dream....

Google has much riding on convincing consumers that AI can be a force for good, or at least not evil. The hot space is increasingly crowded with startups and established players such as OpenAI, Anthropic, Apple and Facebook parent company Meta. The Google-funded shorts, which are 15 to 20 minutes long, aren't commercials for AI, per se. Rather, Google is looking to fund films that explore the intersection of humanity and technology, said Mira Lane, vice president of technology and society at Google. Google is not pushing their products in the movies, and the films are not made with AI, she added... The company said it wants to fund many more movies, but it does not have a target number. Some of the shorts could eventually become full-length features, Google said....

Negative public perceptions about AI could put tech companies at a disadvantage when such cases go before juries of laypeople. That's one reason why firms are motivated to makeover AI's reputation. "There's an incredible amount of skepticism in the public world about what AI is and what AI will do in the future," said Sean Pak, an intellectual property lawyer at Quinn Emanuel, on a conference panel. "We, as an industry, have to do a better job of communicating the public benefits and explaining in simple, clear language what it is that we're doing and what it is that we're not doing."

Astronomers have confirmed the existence of a bizarre planet in the Nu Octantis binary star system that orbits in reverse between two stars -- one of which is now a white dwarf. This retrograde orbit, once thought impossible, defies traditional planetary formation models and may have resulted from dramatic shifts in the system's history. New Scientist reports: The key observation was that the Nu Octantis planet is retrograde -- the planet and one star both orbit the second star, but they do so in opposite directions, with the planet having the tighter orbit around the second star. [Man Hoi Lee at the University of Hong Kong] says this is unusual but makes the system's configuration stable -- even though it means that the planet repeatedly moves through the narrow space between the two stars. His team was able to determine this with lots of certainty thanks to improved measuring devices, such as the HARPS spectrograph at the European Southern Observatory's 3.6-metre telescope in Chile. The fact that the planet's signal persisted through years of observation helped too. "We are pretty sure [the planet] is real, because if it was something like stellar activity, it shouldn't be so consistent in years of data," says Lee.

But this backwards-moving planet isn't the only exotic feature of Nu Octantis. The researchers used the European Southern Observatory's Very Large Telescope, also in Chile, to determine that one of its stars is a white dwarf, which means that it has reached the end of its life cycle, becoming denser and smaller. Lee says this complicates the Nu Octantis threesome's history because mathematical models of its past show that the planet's current orbit was impossible when this star was younger, bigger and brighter. So, the planet either used to orbit both stars at once, but then radically shifted trajectory when one of the two stars became a white dwarf, or it was formed from the mass that the star ejected as it transformed into a white dwarf. Future observations, and a lot more mathematical modelling, may be able to pinpoint which of these scenarios is more likely to have occurred, but both are rather novel, says Lee. The research has been published in the journal Nature.

China has achieved substantial technological advances across robotics, AI, and semiconductor manufacturing as part of a seven-year self-reliance campaign that has tripled the country's research and development spending to $500 billion annually.

Chinese robot manufacturers captured nearly half of their domestic market by 2023, up from a quarter of installations just years earlier, while AI startups now rival OpenAI and Google in capabilities. The progress extends to semiconductors, where Huawei released a high-end smartphone powered by what industry analysts believe was a locally-produced advanced processor, despite U.S. export controls targeting China's chip access.

Morgan Stanley projects China's self-sufficiency in graphics processing units will jump from 11% in 2021 to 82% by 2027. Chinese companies have been purchasing as many industrial robots as the rest of the world combined, enabling highly automated factories that can operate in darkness. In space technology, Chinese firms won five of 11 gold medals when U.S. think tanks ranked the world's best commercial satellite systems last year, compared to four for American companies.

Wisk Aero and NASA have signed a new five-year partnership to advance the safe integration of autonomous, all-electric aircraft into U.S. airspace, focusing on urban air mobility and regulated eVTOL flight. Electrek reports: Wisk Aero shared details of its refreshed partnership with NASA this week. The autonomous aviation specialist has signed a new five-year Non-Reimbursable Space Act Agreement (NRSAA) with the renowned space administration. Per Wisk, this new agreement focuses on critical research led by NASA's Air Traffic Management Exploration (ATM-X) project, which is centered around the advancement of commercialized autonomous aircraft travel under Instrument Flight Rules (IFR) in the National Airspace System (NAS).

As a specialist in autonomous, zero-emission aircraft, Wisk intends to continue its research alongside NASA to help regulators determine future eVTOL flight procedures and capabilities in the US. Regulatory developments on the to-do list for the latest NRSAA include optimizing airspace and route designs for highly automated UAM operations, establishing critical aircraft and ground-based safety system requirements for autonomous flight in urban environments, and establishing Air Traffic Control (ATC) communication protocols and procedures for seamless integration of future UAM aircraft. To achieve these goals, Wisk said its research with NASA will more specifically focus on utilizing advanced simulation and Live Virtual Constructive (LVC) flight environments, which combine live flights with a simulated airspace to enable researchers to assess future operations.

The teams from Wisk and NASA already met last month, continuing their research while beginning to determine how instrument flight procedures and advanced technologies can work together to enable safe autonomous passenger flights by 2030. Wisk Aero is a wholly owned subsidiary of Boeing based in California. The aerospace manufacturer said last year that it expects its pilotless air-taxi to begin carrying passengers "later in the decade."

Scientists have discovered a previously unknown bacterium aboard China's Tiangong space station. "It has been named Niallia tiangongensis, and it inhabited the cockpit controls on the station, living in microgravity conditions," reports Wired. From the report: According to China Central Television, the country's national broadcaster, taikonauts (Chinese astronauts) collected swab samples from the space station in May 2023, which were then frozen and sent back to Earth for study. The aim of this work was to investigate the behavior of microorganisms, gathered from a completely sealed environment with a human crew, during space travel, as part of the China Space Station Habitation Area Microbiome Program (CHAMP). A paper published in the Journal of Systematic and Evolutionary Microbiology describes how analysis of samples from the space station revealed this previously unseen bacterial species, which belongs to the genus Niallia. Genomic sequencing showed that its closest terrestrial relative is the bacterium Niallia circulans, although the Tiangong species has substantial genetic differences. [...]

It is unclear whether the newly discovered microbe evolved on the space station or whether it is part of the vast sea of as yet unidentified microorganisms on Earth. To date, tens of thousands of bacterial species have been cataloged, although there are estimated to be billions more unclassified species on Earth. The discovery of Niallia tiangongensis will provide a better understanding of the microscopic hazards that the next generation of space travelers will face and help design sanitation protocols for extended missions. It is still too early to determine whether the space bacterium poses any danger to taikonauts aboard Tiangong, although it is known that its terrestrial relative, Niallia circulans, can cause sepsis, especially in immunocompromised people.

Starfish Space plans to perform the first commercial satellite docking in orbit with its Otter Pup 2 mission, aiming to connect to an unprepared D-Orbit ION spacecraft using an electrostatic capture mechanism and autonomous navigation software. NASASpaceFlight.com reports: This follows the company's first attempt, which saw the Otter Pup 1 mission unable to dock with its target due to a thruster failure. The Otter Pup 2 spacecraft will be deployed from a quarter plate on the upper stage adapter of the SpaceX Falcon 9 rocket, placing it into a sun synchronous orbit altitude of 510 km inclined 97.4 degrees. The target will be a D-Orbit ION spacecraft which will simulate a client payload, which is not equipped with a traditional docking adapter or capture plate as you might see aboard a space station or other rendezvous target. Instead, Starfish Space's Nautilus capture mechanism will feature a special end effector connected to the end of the capture mechanism. This end effector will enable Otter Pup 2 to dock with the ION through electrostatic adhesion.

"An electromagnet will be integrated into the end effector and will be used as a backup option to the electrostatic end effector, to dock with the ION through magnetic attraction," the company notes. The goal is to eventually commission its Otter satellite servicing vehicle to allow for servicing of previously launched satellites. The company's first Otter missions include customers such as NASA, the U.S. Space Force, and Intelsat, with the goal of flying those missions as soon as 2026. [...] Following the thruster issues on the first mission, this flight will feature two ThrustMe thrusters, which use an electric propulsion system based on gridded ion thruster technology.

A new study reveals that about 3.8 million years after the solar system's first solids formed, Jupiter was twice its current size with a magnetic field 50 times stronger, profoundly influencing the structure of the early solar system. Phys.Org reports: [Konstantin Batygin, professor of planetary science at Caltech] and [Fred C. Adams, professor of physics and astronomy at the University of Michigan] approached this question by studying Jupiter's tiny moons Amalthea and Thebe, which orbit even closer to Jupiter than Io, the smallest and nearest of the planet's four large Galilean moons. Because Amalthea and Thebe have slightly tilted orbits, Batygin and Adams analyzed these small orbital discrepancies to calculate Jupiter's original size: approximately twice its current radius, with a predicted volume that is the equivalent of over 2,000 Earths. The researchers also determined that Jupiter's magnetic field at that time was approximately 50 times stronger than it is today.

Adams highlights the remarkable imprint the past has left on today's solar system: "It's astonishing that even after 4.5 billion years, enough clues remain to let us reconstruct Jupiter's physical state at the dawn of its existence." Importantly, these insights were achieved through independent constraints that bypass traditional uncertainties in planetary formation models -- which often rely on assumptions about gas opacity, accretion rate, or the mass of the heavy element core. Instead, the team focused on the orbital dynamics of Jupiter's moons and the conservation of the planet's angular momentum -- quantities that are directly measurable.

Their analysis establishes a clear snapshot of Jupiter at the moment the surrounding solar nebula evaporated, a pivotal transition point when the building materials for planet formation disappeared and the primordial architecture of the solar system was locked in. The results add crucial details to existing planet formation theories, which suggest that Jupiter and other giant planets around other stars formed via core accretion, a process by which a rocky and icy core rapidly gathers gas. The findings have been published in the journal Nature Astronomy.

Qualcomm announced plans to re-enter the data center market with custom CPUs designed to integrate with Nvidia GPUs and software. As CNBC reports, the move supports Qualcomm's broader strategy to diversify beyond smartphones and into high-growth areas like data centers, PCs, and automotive chips. From the report: "I think we see a lot of growth happening in this space for decades to come, and we have some technology that can add real value added," Cristiano Amon, CEO of Qualcomm, told CNBC in an interview on Monday. "So I think we have a very disruptive CPU." Amon said the company will make an announcement about the CPU roadmap and the timing of its release "very soon," without offering specifics. The data center CPU market remains highly competitive. Big cloud computing players like Amazon and Microsoft already design and deploy their own custom CPUs. AMD and Intel also have a strong presence.

Addressing the competition, Amon said that there will be a place for Qualcomm in the data center CPU space. "As long as ... we can build a great product, we can bring innovation, and we can add value with some disruptive technology, there's going to be room for Qualcomm, especially in the data center," Amon said. "[It] is a very large addressable market that will that will see a lot of investment for decades to come." Last week, Qualcomm signed a memorandum of understanding with Saudi-based AI frim Humain to develop data centers, joining a slew of U.S. tech companies making deals in the region. Humain will operate under Saudi Arabia's Public Investment Fund.

An anonymous reader quotes a report from Bloomberg: While using website data to build a Google Search topped with artificial intelligence-generated answers, an Alphabet executive acknowledged in an internal document that there was an alternative way to do things: They could ask web publishers for permission, or let them directly opt out of being included. But giving publishers a choice would make training AI models in search too complicated, the company concludes in the document, which was unearthed in the company's search antitrust trial.

It said Google had a "hard red line" and would require all publishers who wanted their content to show up in the search page to also be used to feed AI features. Instead of giving options, Google decided to "silently update," with "no public announcement" about how they were using publishers' data, according to the document, written by Chetna Bindra, a product management executive at Google Search. "Do what we say, say what we do, but carefully." "It's a little bit damning," said Paul Bannister, the chief strategy officer at Raptive, which represents online creators. "It pretty clearly shows that they knew there was a range of options and they pretty much chose the most conservative, most protective of them -- the option that didn't give publishers any controls at all."

For its part, Google said in a statement to Bloomberg: "Publishers have always controlled how their content is made available to Google as AI models have been built into Search for many years, helping surface relevant sites and driving traffic to them. This document is an early-stage list of options in an evolving space and doesn't reflect feasibility or actual decisions." They added that Google continually updates its product documentation for search online.

It's a nonprofit that's provide hosting for the Linux Foundation, the Apache Software Foundation, Drupal, Firefox, and 160 other projects — delivering nearly 430 terabytes of information every month. (It's currently hosting Debian, Fedora, and Gentoo Linux.) But hosting only provides about 20% of its income, with the rest coming from individual and corporate donors (including Google and IBM). "Over the past several years, we have been operating at a deficit due to a decline in corporate donations," the Open Source Lab's director announced in late April.

It's part of the CS/electrical engineering department at Oregon State University, and while the department "has generously filled this gap, recent changes in university funding makes our current funding model no longer sustainable. Unless we secure $250,000 in committed funds, the OSL will shut down later this year."

But "Thankfully, the call for support worked, paving the way for the OSU Open Source Lab to look ahead, into what the future holds for them," reports the blog It's FOSS.

"Following our OSL Future post, the community response has been incredible!" posted director Lance Albertson. "Thanks to your amazing support, our team is funded for the next year. This is a huge relief and lets us focus on building a truly self-sustaining OSL." To get there, we're tackling two big interconnected goals:

1. Finding a new, cost-effective physical home for our core infrastructure, ideally with more modern hardware.
2. Securing multi-year funding commitments to cover all our operations, including potential new infrastructure costs and hardware refreshes.


Our current data center is over 20 years old and needs to be replaced soon. With Oregon State University evaluating the future of this facility, it's very likely we'll need to relocate in the near future. While migrating to the State of Oregon's data center is one option, it comes with significant new costs. This makes finding free or very low-cost hosting (ideally between Eugene and Portland for ~13-20 racks) a huge opportunity for our long-term sustainability. More power-efficient hardware would also help us shrink our footprint.

Speaking of hardware, refreshing some of our older gear during a move would be a game-changer. We don't need brand new, but even a few-generations-old refurbished systems would boost performance and efficiency. (Huge thanks to the Yocto Project and Intel for a recent hardware donation that showed just how impactful this is!) The dream? A data center partner donating space and cycled-out hardware. Our overall infrastructure strategy is flexible. We're enhancing our OpenStack/Ceph platforms and exploring public cloud credits and other donated compute capacity. But whatever the resource, it needs to fit our goals and come with multi-year commitments for stability. And, a physical space still offers unique value, especially the invaluable hands-on data center experience for our students....

[O]ur big focus this next year is locking in ongoing support — think annualized pledges, different kinds of regular income, and other recurring help. This is vital, especially with potential new data center costs and hardware needs. Getting this right means we can stop worrying about short-term funding and plan for the future: investing in our tech and people, growing our awesome student programs, and serving the FOSS community. We're looking for partners, big and small, who get why foundational open source infrastructure matters and want to help us build this sustainable future together.
The It's FOSS blog adds that "With these prerequisites in place, the OSUOSL intends to expand their student program, strengthen their managed services portfolio for open source projects, introduce modern tooling like Kubernetes and Terraform, and encourage more community volunteers to actively contribute."

Thanks to long-time Slashdot reader I'm just joshin for suggesting the story.

Australia's first orbital-class rocket launch was delayed after the nose cone of Gilmour Space's Eris rocket unexpectedly detached due to an electrical fault during final preparations. Although no damage occurred and no payload was onboard, the company is postponing the launch to investigate and replace the fairing before attempting another test flight. Ars Technica reports: Gilmour, the Australian startup that developed the Eris rocket, announced the setback in a post to the company's social media accounts Thursday. "During final launch preparations last night, an electrical fault triggered the system that opens the rocket's nose cone (the payload fairing)," Gilmour posted on LinkedIn. "This happened before any fuel was loaded into the vehicle. Most importantly, no one was injured, and early checks show no damage to the rocket or the launch pad."

Gilmour was gearing up for a launch attempt from a privately owned spaceport in the Australian state of Queensland early Friday, local time (Thursday in the United States). The company's Eris rocket, which was poised for its first test flight, stands about 82 feet (25 meters) tall with its payload fairing intact. It's designed to haul a payload of about 670 pounds (305 kilograms) to low-Earth orbit.

While Gilmour didn't release any photos of the accident, a company spokesperson confirmed to Ars that the payload fairing "deployed" after the unexpected electrical issue triggered the separation system. Payload fairings are like clamshells that enclose the satellites mounted to the top of their launch vehicle, protecting them from weather on the launch pad and from airflow as the rocket accelerates to supersonic speeds. Once in space, the rocket releases the payload shroud, usually in two halves. There were no satellites aboard the rocket as Gilmour prepared for its first test flight. The report notes that the Eris rocket is aiming to "become the first all-Australian launcher to reach orbit."

NASA engineers have successfully revived Voyager 1's backup thrusters, unused since 2004 and once considered defunct. Space.com reports: This remarkable feat became necessary because the spacecraft's primary thrusters, which control its orientation, have been degrading due to residue buildup. If its thrusters fail completely, Voyager 1 could lose its ability to point its antenna toward Earth, therefore cutting off communication with Earth after nearly 50 years of operation. To make matters more urgent, the team faced a strict deadline while trying to remedy the thruster situation. After May 4, the Earth-based antenna that sends commands to Voyager 1 -- and its twin, Voyager 2 -- was scheduled to go offline for months of upgrades. This would have made timely intervention impossible.

To solve the problem, NASA's team had to reactivate Voyager 1's long-dormant backup roll thrusters and then attempt to restart the heaters that keep them operational. If the star tracker drifted too far from its guide star during this process, the roll thrusters would automatically fire as a safety measure -- but if the heaters weren't back online by then, firing the thrusters could cause a dangerous pressure spike. So, the team had to precisely realign the star tracker before the thrusters engaged. Because Voyager is so incredibly distant, the team faced an agonizing 23-hour wait for the radio signal to travel all the way back to Earth. If the test had failed, Voyager might have already been in serious trouble. Then, on March 20, their patience was finally rewarded when Voyager responded perfectly to their commands. Within 20 minutes of receiving the signal, the team saw the thruster heaters' temperature soar -- a clear sign that the backup thrusters were firing as planned. "It was such a glorious moment. Team morale was very high that day," Todd Barber, the mission's propulsion lead at JPL, said in the statement. "These thrusters were considered dead. And that was a legitimate conclusion. It's just that one of our engineers had this insight that maybe there was this other possible cause, and it was fixable. It was yet another miracle save for Voyager."

Microsoft has released Command Palette, an enhanced version of its PowerToys Run launcher introduced five years ago. The utility, aimed at power users and developers, provides quick access to applications, files, calculations, and system commands through a Spotlight-like interface.

Command Palette integrates the previously separate Window Walker functionality for switching between open windows and supports launching command prompts, executing web searches, and navigating folder structures. Unlike its predecessor, the new launcher offers full customization via extensions, allowing users to implement additional commands beyond default capabilities. Available through the PowerToys application since early April, Command Palette can be triggered using Win+Alt+Space after installation

A new set of 27 Linux kernel patches introduces a "Swap Tables" mechanism aimed at enhancing virtual memory management. As Phoronix's Michael Larabel reports, "the hope is for lower memory use, higher performance, dynamic swap allocation and growth, greater extensibility, and other improvements over the existing swap code within the Linux kernel." From the report: Engineer Kairui Song with Tencent posted the Swap Table patch series today for implementing the design ideas discussed in recent months by kernel developers. The results are very exciting so let's get straight to it: "With this series, swap subsystem will have a ~20-30% performance gain from basic sequential swap to heavy workloads, for both 4K and mTHP folios. The idle memory usage is already much lower, the average memory consumption is still the same or will also be even lower (with further works). And this enables many more future optimizations, with better defined swap operations." "The patches also clean-up and address various historical issues with the SWAP subsystem," notes Larabel.

Context: In Linux, swap space acts as an overflow for RAM, storing inactive memory pages on disk to free up RAM for active processes. Traditional swap mechanisms are limited in flexibility and performance. The proposed "Swap Tables" aim to address these issues by allowing more efficient and dynamic management of swap space, potentially leading to better system responsiveness and resource utilization.

China launched 12 satellites on Wednesday as part of the âoeThree-Body Computing Constellation,â the worldâ(TM)s first dedicated orbital computing network led by ADA Space and Zhejiang Lab. SpaceNews reports: A Long March 2D rocket lifted off at 12:12 a.m. Eastern (0412 UTC) May 14 from Jiuquan Satellite Launch Center in northwest China. Insulation tiles fell away from the payload fairing as the rocket climbed into a clear blue sky above the spaceport. The China Aerospace Science and Technology Corporation (CASC) announced a fully successful launch, revealing the mission to have sent 12 satellites for a space computing constellation into orbit. Commercial company ADA Space released further details, stating that the 12 satellites form the "Three-Body Computing Constellation," which will directly process data in space, rather than on the ground, reducing reliance on ground-based computing infrastructure. The constellation will be capable of a combined 5 peta operations per second (POPS) with 30 terabytes of onboard storage.

The satellites feature advanced AI capabilities, up to 100 Gbps laser inter-satellite links and remote sensing payloads -- data from which will be processed onboard, reducing data transmission requirements. One satellite also carries a cosmic X-ray polarimeter developed by Guangxi University and the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC), which will detect, identify and classify transient events such as gamma-ray bursts, while also triggering messages to enable followup observations by other missions. [...] The company says the constellation can meet the growing demand for real-time computing in space, as well as help China take the lead globally in building space computing infrastructure, seize the commanding heights of this future industry. The development could mark the beginning of space-based cloud computing as a new capability, as well as open a new arena for strategic competition with the U.S. You can watch a recording of the launch here.
