Scientists Confirmed What Is Inside Our Moon (sciencealert.com) 36

alternative_right shares a report from ScienceAlert: A thorough investigation published in May 2023 found that the inner core of the Moon is, in fact, a solid ball with a density similar to that of iron. To figure it out once and for all, [astronomer Arthur Briaud of the French National Centre for Scientific Research in France] and his colleagues collected data from space missions and lunar laser-ranging experiments to compile a profile of various lunar characteristics. These include the degree of its deformation by its gravitational interaction with Earth, the variation in its distance from Earth, and its density.

... they found that the lunar core is very similar to that of Earth â" with an outer fluid layer and a solid inner core. According to their modeling, the outer core has a radius of about 362 kilometers (225 miles), and the inner core has a radius of about 258 kilometers (160 miles). That's about 15 percent of the entire radius of the Moon. The inner core, the team found, also has a density of about 7,822 kilograms per cubic meter. That's very close to the density of iron. [...]

Singapore To Trial Tokenized Bills, Bring In Stablecoin Laws (reuters.com) 4

An anonymous reader quotes a report from Reuters: Singapore's central bank will hold trials to issue tokenized MAS bills next year and bring in laws to regulate stablecoins as it presses forward with plans to build a scalable and secure tokenised financial ecosystem, the bank's top official said on Thursday. "Tokenization has lifted off the ground. But have asset-backed tokens achieved escape velocity? Not yet," said Chia Der Jiun, Managing Director of the Monetary Authority of Singapore (MAS), a keynote address at the Singapore FinTech Festival.

He said MAS has been working on the details of its stablecoin regulatory regime and will prepare draft legislation, with the emphasis on "sound reserve backing and redemption reliability." MAS is also supporting trials under the BLOOM initiative, which explores the use of tokenized bank liabilities and regulated stablecoins for settlement, he added. "In the CBDC space, I am pleased to announce that the three Singapore banks, DBS, OCBC, and UOB, have successfully conducted interbank overnight lending transactions using the first live trial issuance of Singapore dollar wholesale CBDC," he said. MAS will expand trials to include tokenized MAS bills settled with CBDC, he added.

Blue Origin Sticks First New Glenn Rocket Landing and Launches NASA Spacecraft (techcrunch.com) 68

An anonymous reader quotes a report from TechCrunch: Jeff Bezos' Blue Origin has landed the booster of its New Glenn mega-rocket on a drone ship in the Atlantic Ocean on just its second attempt -- making it the second company to perform such a feat, following Elon Musk's SpaceX. It's an accomplishment that will help the new rocket system become an option to send larger payloads to space, the Moon, and beyond. Thursday's launch wasn't just about the landing attempt, though. Roughly 34 minutes after takeoff, the upper stage of New Glenn successfully deployed the rocket's first commercial payload: twin spacecraft for NASA that will travel to Mars to study the red planet's atmosphere. The pair of achievements are remarkable for the second-ever launch of such a massive rocket system. And it could put Blue Origin in position to compete with SpaceX, which dominates the world's launch market with its Falcon 9, Falcon Heavy, and Starship rockets. You can watch a recording of the launch here.

Mozilla Launches AI Window for Firefox (mozilla.org) 42

Mozilla announced on Thursday that it is building an AI Window for Firefox, a new opt-in browsing mode that will let users interact with an AI assistant and chatbot. The feature will become one of three browsing experiences in Firefox alongside the existing classic and private windows. Users will be able to select which AI model they want to use in the AI Window, according to a post on the Mozilla Connect forum.

The company opened a waitlist for users who want to receive updates and be among the first to test the feature. Mozilla described the AI Window as an "intelligent and user-controlled space" that it is developing in the open through community feedback. Users who try the feature and decide against it can switch it off entirely.

Scientists Watch Supernova Shockwave Shoot Through a Dying Star For First Time (space.com) 9

For the first time, astronomers captured the shockwave of a supernova bursting through the surface of a dying red supergiant star, revealing a surprisingly symmetrical, grape-shaped explosion. Space.com reports: Seeing this moment in detail has previously been elusive because it's rare for a supernova to be spotted early enough and for telescopes to be trained on it -- and when they have been, the exploding star has been too far away. So, when supernova 2024ggi went boom on April 10, 2024 in the relatively nearby spiral galaxy NGC 3621, which is 22 million light-years away in the constellation of Hydra, the Water Snake, astronomer Yi Yang of Tsinghua University in Beijing knew he had to act.

Although the supernova itself couldn't be resolved as anything put a point of light, the polarization of that light held the clues as to the geometry of the breakout. "The geometry of a supernova explosion provides fundamental information on stellar evolution and the physical processes leading to these cosmic fireworks," said Yang. "Spectropolarimetry delivers information about the geometry of the explosion that other types of observation cannot provide because the angular scales are too tiny," said another team-member, Lifan Wang of Texas A&M University.

The measurement showed that the shape of the breakout explosion was flattened, like an olive or grape. Crucially, though, the explosion propagated symmetrically, and continued to do so even when it collided with a ring of circumstellar material. "These findings suggest a common physical mechanism that drives the explosion of many massive stars, which manifests a well-defined axial symmetry and acts on large scales," said Yang. The findings will allow astronomers to rule out some models and strengthen others that describe what drives the shockwave in a supernova explosion.
The findings have been described in a paper on the ESO website.

Sun Unleashes Strongest Solar Flare of 2025 25

New submitter UsRanger175 shares a report from Space.com: The sun erupted in spectacular fashion this morning (Nov. 11), unleashing a major X5.1-class solar flare, the strongest of 2025 so far and the most intense since October 2024. The eruption peaked at 5 a.m. EST (1000 GMT) from sunspot AR4274, which has been bursting with activity in recent days. The blast triggered strong (R3-level) radio blackouts across Africa and Europe, disrupting high-frequency radio communications on the sunlit side of Earth.

This outburst is the latest in a series of intense flares from AR4274, which also produced an X1.7 flare on Nov. 9 and an X1.2 on Nov. 10. Those flares were accompanied by coronal mass ejections (CMEs) that could combine and impact Earth overnight tonight, possibly triggering strong (G3) geomagnetic storm conditions and widespread auroras, according to NOAA's Space Weather Prediction Center. The CME released today could also join the party as it speeds toward Earth at 4.4 million mph. NOAA predicts the CME could impact Earth around midday on Nov. 12. With this third CME added to the mix, it's possible that we could experience severe (G4) geomagnetic storm conditions.

Google Is Introducing Its Own Version of Apple's Private AI Cloud Compute 23

Google has unveiled Private AI Compute, a cloud platform designed to deliver advanced AI capabilities while preserving user privacy. As The Verge notes, the feature is "virtually identical to Apple's Private Cloud Compute." From the report: Many Google products run AI features like translation, audio summaries, and chatbot assistants, on-device, meaning data doesn't leave your phone, Chromebook, or whatever it is you're using. This isn't sustainable, Google says, as advancing AI tools need more reasoning and computational power than devices can supply. The compromise is to ship more difficult AI requests to a cloud platform, called Private AI Compute, which it describes as a "secure, fortified space" offering the same degree of security you'd expect from on-device processing. Sensitive data is available "only to you and no one else, not even Google."

The Linux Kernel Looks To 'Bite the Bullet' In Enabling Microsoft C Extensions (phoronix.com) 44

Linux kernel developers are moving toward enabling Microsoft C Extensions (-fms-extensions) by default in Linux 6.19, with Linus Torvalds signaling no objection. While some dislike relying on Microsoft-style behavior, the patches in kbuild-next suggest the project is ready to "bite the bullet" and adopt the extensions system-wide. Phoronix reports: Rasmus Villemoes argued with Kbuild: enable -fms-extensions that would allow for "prettier code" and others have noted in the past the potential for saving stack space and all around being beneficial in being able to leverage the Microsoft C behavior: "Once in a while, it turns out that enabling -fms-extensions could allow some slightly prettier code. But every time it has come up, the code that had to be used instead has been deemed 'not too awful' and not worth introducing another compiler flag for. That's probably true for each individual case, but then it's somewhat of a chicken/egg situation. If we just 'bite the bullet' as Linus says and enable it once and for all, it is available whenever a use case turns up, and no individual case has to justify it..."

The second patch is kbuild: Add '-fms-extensions' to areas with dedicated CFLAGS to ensure -fms-extensions is passed for the CPU architectures that rely on their own CFLAGS being set rather than the main KBUILD_CFLAGS. Linus Torvalds chimed in on the prior mailing list discussion and doesn't appear to be against enabling -fms-extensions beginning with the Linux 6.19 kernel.

What's the Best Ways for Humans to Explore Space? (noemamag.com) 95

Should we leave space exploration to robots — or prioritize human spaceflight, making us a multiplanetary species?

Harvard professor Robin Wordsworth, who's researched the evolution and habitability of terrestrial-type planets, shares his thoughts: In space, as on Earth, industrial structures degrade with time, and a truly sustainable life support system must have the capability to rebuild and recycle them. We've only partially solved this problem on Earth, which is why industrial civilization is currently causing serious environmental damage. There are no inherent physical limitations to life in the solar system beyond Earth — both elemental building blocks and energy from the sun are abundant — but technological society, which developed as an outgrowth of the biosphere, cannot yet exist independently of it. The challenge of building and maintaining robust life-support systems for humans beyond Earth is a key reason why a machine-dominated approach to space exploration is so appealing...

However, it's notable that machines in space have not yet accomplished a basic task that biology performs continuously on Earth: acquiring raw materials and utilizing them for self-repair and growth. To many, this critical distinction is what separates living from non-living systems... The most advanced designs for self-assembling robots today begin with small subcomponents that must be manufactured separately beforehand. Overall, industrial technology remains Earth-centric in many important ways. Supply chains for electronic components are long and complex, and many raw materials are hard to source off-world... If we view the future expansion of life into space in a similar way as the emergence of complex life on land in the Paleozoic era, we can predict that new forms will emerge, shaped by their changed environment, while many historical characteristics will be preserved. For machine technology in the near term, evolution in a more life-like direction seems likely, with greater focus on regenerative parts and recycling, as well as increasingly sophisticated self-assembly capabilities. The inherent cost of transporting material out of Earth's gravity well will provide a particularly strong incentive for this to happen.

If building space habitats is hard and machine technology is gradually developing more life-like capabilities, does this mean we humans might as well remain Earth-bound forever? This feels hard to accept because exploration is an intrinsic part of the human spirit... To me, the eventual extension of the entire biosphere beyond Earth, rather than either just robots or humans surrounded by mechanical life-support systems, seems like the most interesting and inspiring future possibility. Initially, this could take the form of enclosed habitats capable of supporting closed-loop ecosystems, on the moon, Mars or water-rich asteroids, in the mold of Biosphere 2. Habitats would be manufactured industrially or grown organically from locally available materials. Over time, technological advances and adaptation, whether natural or guided, would allow the spread of life to an increasingly wide range of locations in the solar system.

The article ponders the benefits (and the history) of both approaches — with some fasincating insights along the way.

"If genuine alien life is out there somewhere, we'll have a much better chance of comprehending it once we have direct experience of sustaining life beyond our home planet."

Blue Origin Postpones Attempt to Launch Unique ''EscaPADE' Orbiters to Mars (cnn.com) 33

UPDATE (1:16 PST) Today's launch has been scrubbed due to weather, and Blue Origin is now reviewing opportunities for new launch windows.

Sunday Morning Blue Origin livestreamed the planned launch of its New Glenn rocket, which will carry a very unique mission for NASA. "Twin spacecraft are set to take off on an unprecedented, winding journey to Mars," reports CNN, "where they will investigate why the barren red planet began to lose its atmosphere billions of years ago." By observing two Mars locations simultaneously, this mission can measure how Mars responds to space weather in real time — and how the Martian magnetosphere changes... Called EscaPADE, the mission will aim for an orbital trajectory that has never been attempted before, according to aerospace company Advanced Space, which is supporting the project. If successful, it could be a crucial case study that can allow extraordinary flexibility for planetary science missions down the road. The robotic mission plans to spend a year idling in an orbital backroad before heading to its target destination... [R]ather than turning toward Mars, the two orbiters will instead aim for Lagrange Point 2, or L2 — a cosmic balance point about 1.5 million kilometers (930,000 miles) from Earth. Lagrange points are special because they act as gravitational wells in which the pull of the sun and Earth are in perfect balance. The conditions can allow spacecraft to linger without being dragged away... The spacecraft will then loop endlessly in a kidney bean-shaped orbit around L2 until next year's Mars transfer window opens.
This "launch and loiter" project is part of NASA's SIMPLEx [Small, Innovative Missions for Planetary Exploration] program, which seeks high-value missions for less money, notes CNN. "EscaPADE's cost was less than $100 million, compared with the roughly $300 million to $600 million price tags of other NASA satellites orbiting Mars."

"Blue Origin is also attempting to land and recover New Glenn's first-stage booster," notes another CNN article.

Neurodiverse Professionals 25% More Satisfied With AI Tools and Agents (cnbc.com) 30

An anonymous reader shared this report from CNBC: Neurodiverse professionals may see unique benefits from artificial intelligence tools and agents, research suggests. With AI agent creation booming in 2025, people with conditions like ADHD, autism, dyslexia and more report a more level playing field in the workplace thanks to generative AI. A recent study from the UK's Department for Business and Trade found that neurodiverse workers were 25% more satisfied with AI assistants and were more likely to recommend the tool than neurotypical respondents. [The study involved 1,000 users of Microsoft 365 Copilot from October through December of 2024.]

"Standing up and walking around during a meeting means that I'm not taking notes, but now AI can come in and synthesize the entire meeting into a transcript and pick out the top-level themes," said Tara DeZao, senior director of product marketing at enterprise low-code platform provider Pega. DeZao, who was diagnosed with ADHD as an adult, has combination-type ADHD, which includes both inattentive symptoms (time management and executive function issues) and hyperactive symptoms (increased movement). "I've white-knuckled my way through the business world," DeZao said. "But these tools help so much...."

Generative AI happens to be particularly adept at skills like communication, time management and executive functioning, creating a built-in benefit for neurodiverse workers who've previously had to find ways to fit in among a work culture not built with them in mind. Because of the skills that neurodiverse individuals can bring to the workplace — hyperfocus, creativity, empathy and niche expertise, just to name a few — some research suggests that organizations prioritizing inclusivity in this space generate nearly one-fifth higher revenue. "Investing in ethical guardrails, like those that protect and aid neurodivergent workers, is not just the right thing to do," said Kristi Boyd, an AI specialist with the SAS data ethics practice. "It's a smart way to make good on your organization's AI investments."

China Delays Shenzhou-20 Crew Return After Suspected Space Debris Impact (spacenews.com) 29

China has delayed the return of its Shenzhou-20 crewed spacecraft after it was suspected to have been struck by space debris while docked at the Tiangong space station. "The Shenzhou-20 crewed spacecraft is suspected of being struck by a small piece of space debris, and impact analysis and risk assessment are underway," the China Manned Space Engineering Office (CMSEO) statement Nov. 5 read. "To ensure the safety and health of the astronauts and the complete success of the mission, it has been decided that the Shenzhou-20 return mission, originally scheduled for Nov. 5, will be postponed." SpaceNews reports: CMSEO did not specify the location of the suspected strike, the extent of any damage, or the data that indicated an impact. No potential dates were noted for a return to Earth. The Shenzhou-20 spacecraft launched April 24, carrying three astronauts -- commander Chen Dong and crewmates Chen Zhongrui and Wang Jie -- to the Tiangong space station. The spacecraft docked at the radial port of Tiangong's Tianhe core module. The crew have completed their six-month-long mission in orbit, and had handed over control of the space station to the newly-arrived Shenzhou-21 crew Nov. 4.

Checks on the Shenzhou-20 spacecraft could include telemetry and leak tests, verifying guidance and propulsion systems, and screening for impacts in accelerometer and acoustic sensor data. A key concern would be potential damage to the spacecraft's thermal protection system or parachute deployment structures, both critical for safe atmospheric reentry and landing. Tiangong features a 10-meter-long robotic arm, capable of crawling, and a smaller, more precise arm. These could be employed to position cameras and provide closeup imagery of a potential impact. Crews may be able to conduct an extravehicular activity (EVA) to assess the situation. Tiangong crews have recently added debris shields during a number of EVAs; the same procedures, tools, and arm support can be adapted for a Shenzhou inspection.

Universe Expansion May Be Slowing, Not Accelerating, Study Suggests (theguardian.com) 90

A new study challenges the Nobel-winning theory that the universe's expansion is accelerating, suggesting instead that it may be slowing down as dark energy weakens -- potentially leading to a future "big crunch" where the cosmos collapses back in on itself. "Our study shows that the universe has already entered a phase of decelerated expansion at the present epoch and that dark energy evolves with time much more rapidly than previously thought," said Prof Young-Wook Lee, of Yonsei University in South Korea, who led the work. "If these results are confirmed, it would mark a major paradigm shift in cosmology since the discovery of dark energy 27 years ago." The Guardian reports: The latest work focuses on the reliability of observations of distant supernovae (exploding stars) that led to the discovery of dark energy, work that was awarded the 2011 Nobel prize in physics. [...] By estimating the ages of 300 host galaxies using a different method, the team concluded that there are simply variations in the properties of stars in the early universe that mean they produce, on average, fainter supernovae. Correcting for this systematic bias still results in an expanding universe, but suggests that the expansion has slowed down and that dark energy is waning, the analysis concluded. If dark energy keeps decreasing to the point where it becomes negative, the universe is theoretically predicted to end in a big crunch. The findings are published in Monthly Notices of the Royal Astronomical Society.

Trump Re-Nominates Billionaire Jared Isaacman To Run NASA (cbsnews.com) 133

President Trump has re-nominated tech billionaire and private astronaut Jared Isaacman to lead NASA, reversing his earlier withdrawal over concerns about Isaacman's political affiliations. CBS News reports: Mr. Trump nominated Isaacman to the Senate-confirmed post last year, but announced in late May he had decided to withdraw Isaacman after a "thorough review" of his "prior associations." Weeks after the withdrawal, the president went further in expressing his concerns about Isaacman's credentials. At the time, Mr. Trump acknowledged that he thought Isaacman "was very good," but had been "surprised to learn" that Isaacman was a "blue-blooded Democrat, who had never contributed to a Republican before." [...]

Mr. Trump made no mention of his previous decision to nominate and then withdraw Isaacman in his Tuesday evening announcement of the re-nomination on his Truth Social platform. "This evening, I am pleased to nominate Jared Isaacman, an accomplished business leader, philanthropist, pilot, and astronaut, as Administrator of NASA," Trump posted. "Jared's passion for Space, astronaut experience, and dedication to pushing the boundaries of exploration, unlocking the mysteries of the universe, and advancing the new Space economy, make him ideally suited to lead NASA into a bold new Era."

The World's Tallest Chip Defies the Limits of Computing: Goodbye To Moore's Law? (elpais.com) 79

Longtime Slashdot reader dbialac shares a report from EL PAIS: For decades, the progress of electronics has followed a simple rule: smaller is better. Since the 1960s, each new generation of chips has packed more transistors into less space, fulfilling the famous Moore's Law. Formulated by Intel co-founder Gordon Moore in 1965, this law predicted that the number of transistors in an integrated circuit approximately doubles each year. But this race to the minuscule is reaching its physical limits. Now, an international team of scientists is proposing a solution as obvious as it is revolutionary: if we can't keep reducing the size of chips, let's build them up.

Xiaohang Li, a researcher at King Abdullah University of Science and Technology (KAUST) in Saudi Arabia, and his team have designed a chip with 41 vertical layers of semiconductors and insulating materials, approximately ten times higher than any previously manufactured chip. The work, recently published in the journal Nature Electronics, not only represents a technical milestone but also opens the door to a new generation of flexible, efficient, and sustainable electronic devices. "Having six or more layers of transistors stacked vertically allows us to increase circuit density without making the devices smaller laterally," Li explains. "With six layers, we can integrate 600% more logic functions in the same area than with a single layer, achieving higher performance and lower power consumption."

Google's Next Moonshot Is Putting TPUs In Space With 'Project Suncatcher' (9to5google.com) 48

Google's new "Project Suncatcher" aims to launch Tensor Processing Units (TPUs) into space, creating a solar-powered, satellite-based AI network capable of scaling machine learning beyond Earth's limits. Google says a "solar panel can be up to 8 times more productive than on earth" for near-continuous power using a "dawn-dusk sun-synchronous low earth orbit" that reduces the need for batteries and other power generation. 9to5Google reports: These satellites would connect via free-space optical links, with large-scale ML workloads "distributing tasks across numerous accelerators with high-bandwidth, low-latency connections." To match data centers on Earth, the connection between satellites would have to be tens of terabits per second, and they'd have to fly in "very close formation (kilometers or less)."

Google has already conducted radiation testing on TPUs (Trillium, v6e), with "promising" results: "While the High Bandwidth Memory (HBM) subsystems were the most sensitive component, they only began showing irregularities after a cumulative dose of 2 krad(Si) -- nearly three times the expected (shielded) five year mission dose of 750 rad(Si). No hard failures were attributable to TID up to the maximum tested dose of 15 krad(Si) on a single chip, indicating that Trillium TPUs are surprisingly radiation-hard for space applications."

Finally, Google believes that launch costs will "fall to less than $200/kg by the mid-2030s." At that point, the "cost of launching and operating a space-based data center could become roughly comparable to the reported energy costs of an equivalent terrestrial data center on a per-kilowatt/year basis."

Could a Faint Glow in the Milky Way Be Dark Matter? (space.com) 47

"A nearby galaxy once thought to be dominated by dark matter seems to have a surprise supermassive black hole at its centre," reports New Scientist.

Yet scientists "are convinced dark matter is out there," writes Space.com. "The quest to detect it arguably remains both one of the most frustrating and most exhilarating challenges in modern physics."

And now they report that the century-old mystery of dark matter — the invisible glue thought to hold galaxies together — "just got a modern clue." Scientists say they may be one step closer to confirming the existence of this elusive material, thanks to new simulations suggesting that a faint glow at the center of the Milky Way could be dark matter's long-sought signature. "It's very hard to actually prove, but it does seem likely," Moorits Muru of the Leibniz Institute for Astrophysics Potsdam in Germany, who led the new study, told Space.com...

The findings, show that dark matter near the Milky Way's center might not form a perfect sphere as scientists long thought. Instead, it appears flattened, almost egg-shaped, and that shape closely mirrors the pattern of mysterious gamma rays observed by NASA's Fermi Gamma-ray Space Telescope... Using powerful supercomputers, [the researchers] recreated how the Milky Way formed, including billions of years of violent collisions and mergers with smaller galaxies. Those violent events, the researchers found, left deep "fingerprints" on the way dark matter is distributed in the galactic core.... matching the pattern of gamma-ray emission Fermi has observed, the new study reports...

If the excess truly arises from dark matter collisions, it would mark the first indirect evidence that weakly interacting massive particles [WIMPs], a leading dark matter candidate, really exist...

"We have run dozens of direct detection experiments around the globe hunting for WIMPS," notes Phys.org, in an article titled "The Empty Search for Dark Matter." We have run dozens of direct detection experiments around the globe hunting for WIMPS — dark matter particles in this particular mass range. And they're not all the same kind of experiments. There are also the scintillators, which use a giant vat of liquefied noble gas, like several tons of xenon. They wait for a dark matter particle to strike the xenon and cause it to scintillate, which is a fancy science word for "sparkle." We see the sparkle; we detect dark matter...

They're just one example of a broader class of dark matter candidates, with delightful names like Q-balls, WIMPzillas, and sterile neutrinos. We've tuned our different experiments to capture different mass ranges or interaction strengths to cover as much of that wide dark matter spectrum as possible. We've even tried to manufacture various kinds of dark matter in our particle collider experiments.

And we've found nothing.

NASA Seeks Backup Plan for Carrying Astronauts to the Moon (cnn.com) 51

An anonymous reader shared this report from CNN: [C]iting delays in Starship's development and competitive pressure from China, NASA asked SpaceX and Blue Origin — which holds a separate lunar lander contract with the space agency — to submit plans to expedite development of their respective spacecraft by October 29. Both companies have responded. But the space agency is also asking the broader commercial space industry to detail how they might get the job done more quickly, hinting that NASA leadership is prepared to sideline its current partners. CNN spoke with half a dozen companies about how they plan to respond to NASA's call to action, which the agency will formally issue once the government shutdown ends, according to a source familiar with the matter.
One possibility is Lockheed Martin... Notably, as a legacy NASA contractor, the company built the $20.4 billion Orion spacecraft that astronauts will ride when they take off from Earth... Now, Lockheed says it can piece together a two-stage lunar lander that uses spare parts harvested from Orion. The company would make use of Space Shuttle-era OMS-E engines — which are also used on Orion — to serve as the propulsion for an "ascent stage" of the lunar lander, providing the thrust for the vehicle to lift off the moon after a mission is completed. But the vehicle also needs a descent stage to get down to the lunar surface in the first place...

Other commercial space companies contacted by CNN — including Firefly Aerospace and Northrop Grumman — said simply that they were "ready to support" NASA in its endeavor to find a faster way to complete the Artemis III mission. They did not confirm whether they would formally respond to the space agency's anticipated request for companies to submit proposals.

The more important goal, argue some experts, is to pave the way for a permanent lunar base where astronauts can live and work... [P]erhaps the true winner will be the country that is able to build lasting infrastructure, experts say. "It makes great press fodder to frame this as competition," said one space policy source, who was among several that spoke to CNN on the condition of anonymity to discuss controversial issues. "But this is about the long game and the sustainability."

Did a Weather Balloon, Not a Mysterious Space Object, Strike That United Airlines Flight? (sfgate.com) 34

Slashdot reader joshuark shares this report from SFGate: The mystery object that struck a plane at 36,000 feet is likely not space debris, as some speculated, but rather a Silicon Valley test project gone wrong...

WindBorne Systems, a Palo Alto startup that uses atmospheric balloons to collect weather data for AI-based forecast models,has come forward to say that they believe they may be responsible for the object that hit the windshield... "At 6am PT, we sent our preliminary investigation to both NTSB and FAA, and are working with both of them to investigate further," [WindBorne's CEO John Dean posted on social media...] WindBorne said the company has launched more than 4,000 balloons and that it coordinates with the Federal Aviation Administration for every launch.

WindBorne "has conducted more than 4,000 launches," the company said in a statement, noting that they've always coordinated those launched with America's Federal Aviation Administration and filed aviation alerts for every launched balloon. Plus "The system is designed to be safe in the event of a midair collision... Our balloon is 2.4 pounds at launch and gets lighter throughout flight." We are working closely with the FAA on this matter. We immediately rolled out changes to minimize time spent between 30,000 and 40,000 feet. These changes are already live with immediate effect. Additionally, we are further accelerating our plans to use live flight data to autonomously avoid planes, even if the planes are at a non-standard altitude. We are also actively working on new hardware designs to further reduce impact force magnitude and concentration.

Security Holes Found in OpenAI's ChatGPT Atlas Browser (and Perplexity's Comet) (scworld.com) 20

The address bar/ChatGPT input window in OpenAI's browser ChatGPT Atlas "could be targeted for prompt injection using malicious instructions disguised as links," reports SC World, citing a report from AI/agent security platform NeuralTrust: NeuralTrust found that a malformed URL could be crafted to include a prompt that is treated as plain text by the browser, passing the prompt on to the LLM. A malformation, such as an extra space after the first slash following "https:" prevents the browser from recognizing the link as a website to visit. Rather than triggering a web search, as is common when plain text is submitted to a browser's address bar, ChatGPT Atlas treats plain text as ChatGPT prompts by default.

An unsuspecting user could potentially be tricked into copying and pasting a malformed link, believing they will be sent to a legitimate webpage. An attacker could plant the link behind a "copy link" button so that the user might not notice the suspicious text at the end of the link until after it is pasted and submitted. These prompt injections could potentially be used to instruct ChatGPT to open a new tab to a malicious website such as a phishing site, or to tell ChatGPT to take harmful actions in the user's integrated applications or logged-in sites like Google Drive, NeuralTrust said.

Last month browser security platform LayerX also described how malicious prompts could be hidden in URLs (as a parameter) for Perplexity's browser Comet. And last week SquareX Labs demonstrated that a malicious browser extension could spoof Comet's AI sidebar feature and have since replicated the proof-of-concept (PoC) attack on Atlas.

But another new vulnerability in ChatGPT Atlas "could allow malicious actors to inject nefarious instructions into the artificial intelligence (AI)-powered assistant's memory and run arbitrary code," reports The Hacker News, citing a report from browser security platform LayerX: "This exploit can allow attackers to infect systems with malicious code, grant themselves access privileges, or deploy malware," LayerX Security Co-Founder and CEO, Or Eshed, said in a report shared with The Hacker News. The attack, at its core, leverages a cross-site request forgery (CSRF) flaw that could be exploited to inject malicious instructions into ChatGPT's persistent memory. The corrupted memory can then persist across devices and sessions, permitting an attacker to conduct various actions, including seizing control of a user's account, browser, or connected systems, when a logged-in user attempts to use ChatGPT for legitimate purposes....

"What makes this exploit uniquely dangerous is that it targets the AI's persistent memory, not just the browser session," Michelle Levy, head of security research at LayerX Security, said. "By chaining a standard CSRF to a memory write, an attacker can invisibly plant instructions that survive across devices, sessions, and even different browsers. In our tests, once ChatGPT's memory was tainted, subsequent 'normal' prompts could trigger code fetches, privilege escalations, or data exfiltration without tripping meaningful safeguards...."

LayerX said the problem is exacerbated by ChatGPT Atlas' lack of robust anti-phishing controls, the browser security company said, adding it leaves users up to 90% more exposed than traditional browsers like Google Chrome or Microsoft Edge. In tests against over 100 in-the-wild web vulnerabilities and phishing attacks, Edge managed to stop 53% of them, followed by Google Chrome at 47% and Dia at 46%. In contrast, Perplexity's Comet and ChatGPT Atlas stopped only 7% and 5.8% of malicious web pages.

From The Conversation: Sandboxing is a security approach designed to keep websites isolated and prevent malicious code from accessing data from other tabs. The modern web depends on this separation. But in Atlas, the AI agent isn't malicious code — it's a trusted user with permission to see and act across all sites. This undermines the core principle of browser isolation.
