On February 24th, the Vera C. Rubin Observatory activated its automated alert system, sending out roughly 800,000 real-time notifications flagging asteroids, supernovae, flaring black holes and "other transient celestial events," reports Scientific American. And this is only the beginning -- that number is projected to climb into the millions as it continues scanning the ever-changing sky. From the report: The astronomical observatory equipped with world's largest camera hit a key milestone on February 24, when a complex data-processing system pushed hundreds of thousands of alerts out to scientists eager to pore over its most exciting sightings. The Vera C. Rubin Observatory began operations last year, capturing stunning, panoramic time-lapse views of the cosmos with ease. Rubin's first images, based on just 10 hours of observations, let space fans zoom seemingly forever into an overwhelmingly starry sky. But watchful astronomers were always awaiting the next step: the system that would automatically alert them to the most promising activity in the overhead sky amid the 1,000 or so enormous images that Rubin's telescope captures every night.

"We can detect everything that changes, moves and appears," said Yusra AlSayyad, an astronomer at Princeton University and Rubin's deputy associate director for data management, to Scientific American last summer. "It's way too much for one person to manually sift through and filter and monitor themselves." So even as they were designing and building the Rubin Observatory itself, scientists were also designing an alert system to help astronomers navigate the flood of data. As soon as the telescope began observations, the team started constructing a static reference image of the entire sky in impeccable detail.

Now the data processing systems that support the observatory are starting to automatically compare every new Rubin image to the corresponding section of that background template. The systems identify all of the differences, each of which is individually flagged. The algorithms can also distinguish between a potential supernova and a possible newfound asteroid, for example. Alerting the scientific community is the final, crucial step. Astronomers -- as well as members of the public -- can sign up for notifications based on the type of sighting they're interested in and the brightness of the observation in question. And now that the alerts system has gone live, users receive a tiny, fuzzy image with some astronomical metadata of each observation that fits their criteria -- all just a couple of minutes after Rubin captures the original image.

Nasa announced on Friday radical changes to its delayed Artemis III mission to land humans back on the moon, as the US space agency grapples with technical glitches and criticism that it is trying to do too much too soon. From a report: The abrupt shift in strategy was laid out by the space agency's recently confirmed administrator, Jared Isaacman. Announcing the changes on Friday, he said that Nasa would introduce at least one new moon flight before attempting to put humans back on the lunar surface for the first time in more than half a century, in 2028.

The new, more incremental approach would give the Nasa team a chance to test flight and refine its technology. As part of the changes, the Artemis II mission to fly humans around the moon this year, without landing, would also be pushed back from its latest scheduled launch on 6 March to 1 April at the earliest.

"Everybody agrees this is the only way forward," Isaacman told reporters at a news conference. "I know this is how Nasa changed the world, and this is how Nasa is going to do it again."

Longtime Slashdot reader ArchieBunker shares a report from NBC News: NASA revealed that astronaut Mike Fincke was the crew member who suffered a medical incident at the International Space Station in January, which prompted the agency to carry out the first evacuation due to a medical issue in the space station's 25-year history. The rare decision to cut a mission short and bring Fincke and three other crew members home early made for a dramatic week in space early this year.

In a statement released by NASA "at the request of Fincke," the veteran astronaut said he experienced a medical event on Jan. 7 "that required immediate attention" from his space station crew members. "Thanks to their quick response and the guidance of our NASA flight surgeons, my status quickly stabilized," Fincke, 58, said in the statement. [...] In his statement, Fincke thanked his Crew-11 colleagues, along with NASA astronaut Chris Williams and Russian cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev, who were also aboard the space station at the time and are still in space. Fincke also thanked the teams at NASA, SpaceX and the medical professionals at Scripps Memorial Hospital La Jolla. "Their professionalism and dedication ensured a positive outcome," he said.

Fincke ended his statement by saying he is "doing very well" and still actively involved with standard post-flight reconditioning at NASA's Johnson Space Center in Houston. "Spaceflight is an incredible privilege, and sometimes it reminds us just how human we are," he said. "Thank you for all your support."

"A surprisingly ravenous black hole from the dawn of the universe is breaking two big rules," reports Live Science. "It's not only exceeding the 'speed limit' of black hole growth but also generating extreme X-ray and radio wave emissions — two features that are not predicted to coexist..."

"How is this rule-breaking behavior even possible? In a paper published Jan. 21 in The Astrophysical Journal, an international team of researchers observed ID830 in multiple wavelengths to find an answer...." As they attract gas and dust, this material accumulates in a swirling accretion disk. Gravity pulls the material from the disk into the black hole, but the infalling material generates radiation pressure that pushes outward and prevents more stuff from falling in. As a result, black holes are muzzled by a self-regulating process called the Eddington limit... Its X-ray brightness suggests that ID830 is accreting mass at about 13 times the Eddington limit, due to a sudden burst of inflowing gas that may have occurred as ID830 shredded and engulfed a celestial body that wandered too close. "For a supermassive black hole (SMBH) as massive as ID830, this would require not a normal (main-sequence) star, but a more massive giant star or a huge gas cloud," study co-author Sakiko Obuchi, an observational astronomer at Waseda University in Tokyo, told Live Science via email. Such super-Eddington phases may be incredibly brief, as "this transitional phase is expected to last for roughly 300 years," Obuchi added.

ID830 also simultaneously displays radio and X-ray emissions. These two features are not expected to coexist, especially because super-Eddington accretion is thought to suppress such emissions. "This unexpected combination hints at physical mechanisms not yet fully captured by current models of extreme accretion and jet launching," the researchers said in a statement. So while ID830 is launching massive radio jets, its X-ray emissions appear to originate from a structure called a corona, produced as intense magnetic fields from the accretion disk create a thin but turbulent billion-degree cloud of turbocharged particles. These particles orbit the black hole at nearly the speed of light, in what NASA calls "one of the most extreme physical environments in the universe." Altogether, ID830's rule-breaking behaviors suggest that it is in a rare transitional phase of excessive consumption — and excretion. This incredible feeding burst has energized both its jets and its corona, making ID830 shine brightly across multiple wavelengths as it spews out excess radiation.

Additionally, based on UV-brightness analysis, quasars like ID830 may be unexpectedly common, the researchers said. Models predict that only around 10% of quasars have spectacular radio jets, but these energetic objects could be significantly more abundant in the early universe than previously suggested. Most importantly, ID830 also shows how SMBHs can regulate galaxy growth in the early universe. As a black hole gobbles matter at the super-Eddington limit, the energy from its resultant emissions can heat and disperse matter throughout the interstellar medium — the gas between stars — to suppress star formation. As a result, ancient SMBHs like ID830 may have grown massive at the expense of their host galaxies.

An anonymous reader quotes a report from NPR: NASA could launch four astronauts on a mission to fly around the moon as soon as March 6th. That's the launch date (PDF) that the space agency is now working towards following a successful test fueling of its big, 322-foot-tall moon rocket, which is standing on a launch pad at the Kennedy Space Center in Florida.

"This is really getting real," says Lori Glaze, acting associate administrator of NASA's exploration systems development mission directorate. "It's time to get serious and start getting excited." But she cautioned that there's still some pending work that remains to be done out at the launch pad, and officials will have to conduct a multi-day flight readiness review late next week to make sure that every aspect of the mission is truly ready to go. "We need to successfully navigate all of those, but assuming that happens, it puts us in a very good position to target March 6th," she says, noting that the flight readiness review will be "extensive and detailed." [...]

When NASA workers first tested out fueling the rocket earlier this month, they encountered problems like a liquid hydrogen leak. Swapping out some seals and other work seems to have fixed these issues, according to officials who say that the latest countdown dress rehearsal went smoothly, despite glitches such as a loss of ground communications in the Launch Control Center that forced workers to temporarily use backups.

An anonymous reader quotes a report from Bloomberg: In early 2024, the agency that oversees cybersecurity for much of the US government issued a rare emergency order -- disconnect your Connect Secure virtual private network software immediately. Chinese spies had hacked the code and infiltrated nearly two dozen organizations. The directive applied to all civilian federal agencies, but given the product's customer base, its impact was more widely felt. The software, which is made by Ivanti Inc., was something of an industry standard across government and much of the corporate world. Clients included the US Air Force, Army, Navy and other parts of the Defense Department, the Department of State, the Federal Aviation Administration, the Federal Reserve, the National Aeronautics and Space Administration, thousands of companies and more than 2,000 banks including Wells Fargo & Co. and Deutsche Bank AG, according to federal procurement records, internal documents, interviews and the accounts of former Ivanti employees who requested anonymity because they were not authorized to disclose customer information.

Soon after sending out their order, which instructed agencies to install an Ivanti-issued fix, staffers at the Cybersecurity and Infrastructure Security Agency discovered that the threat was also inside their own house. Two sensitive CISA databases -- one containing information about personnel at chemical facilities, another assessing the vulnerabilities of critical infrastructure operators -- had been compromised via the agency's own Connect Secure software. CISA had followed all its own guidance. Ivanti's fix had failed. This was a breaking point for some American national security officials, who had long expressed concerns about Connect Secure VPNs. CISA subsequently published a letter with the Federal Bureau of Investigation and the national cybersecurity agencies of the UK, Canada, Australia and New Zealand warning customers of the "significant risk" associated with continuing to use the software. According to Laura Galante, then the top cyber official in the Office of the Director of National Intelligence, the government came to a simple conclusion about the technology. "You should not be using it," she said. "There really is no other way to put it."

That attack, along with several others that successfully targeted the Ivanti software, illustrate how private equity's push into the cybersecurity market ended up compromising the quality and safety of some critical VPN products, Bloomberg has found. Last year, Bloomberg reported that Citrix Systems Inc., another top VPN maker, experienced several major hacks after its private equity owners, Elliott Investment Management and Vista Equity Partners, cut most of the company's 70-member product security team following their acquisition of the company in 2022. Some government officials and private-sector executives are now reconsidering their approach to evaluating cybersecurity software. In addition to excising private equity-owned VPNs from their networks, some factor private equity ownership into their risk assessments of key technologies.

NASA has officially classified Boeing Starliner's 2024 crewed flight as a "Type A" mishap, acknowledging serious technical failures and leadership shortcomings that nearly left astronauts unable to safely return. Administrator Jared Isaacman released (PDF) a 311-page internal report citing flawed decision-making and cultural issues, with the next Starliner flight now planned as uncrewed pending major fixes. Ars Technica reports: As part of the announcement, NASA Administrator Jared Isaacman sent an agency-wide letter that recognized the shortcomings of both Starliner's developer, Boeing, as well as the space agency itself. Starliner flew under the auspices of NASA's Commercial Crew Program, in which the agency procures astronaut transportation services to the International Space Station. "We are taking ownership of our shortcomings," Isaacman said.

"Starliner has design and engineering deficiencies that must be corrected, but the most troubling failure revealed by this investigation is not hardware," Isaacman wrote in his letter to the NASA workforce. "It is decision-making and leadership that, if left unchecked, could create a culture incompatible with human spaceflight." Isaacman said there would be "leadership accountability" as a result of the decisions surrounding the Starliner program, but did not say which actions would be taken.

Cord Cutters News reports: In a move that has delighted fans of classic science fiction, Warner Bros. Discovery has begun uploading full episodes of the iconic series Babylon 5 to YouTube, providing free access to the show just as it departs from the ad-supported streaming platform Tubi... Viewers noticed notifications on Tubi indicating that all five seasons would no longer be available after February 10, 2026, effectively removing one of the most accessible free streaming options for the space opera. With this shift, Warner Bros. Discovery appears to be steering the property toward its own digital ecosystem, leveraging YouTube's vast audience to reintroduce the show to both longtime enthusiasts and a new generation.

The uploads started with the pilot episode, "The Gathering," which serves as the entry point to the series' intricate universe. This was followed by subsequent episodes such as "Midnight on the Firing Line" and "Soul Hunter," released in sequence to build narrative momentum. [Though episodes 2 and 3 are mis-labeled as #3 and #4...] The strategy involves posting one episode each week, allowing audiences to experience the story at a paced rhythm that mirrors the original broadcast schedule...

For Warner Bros. Discovery, this initiative could signal plans to expand the franchise's visibility, especially amid ongoing interest in reboots and spin-offs that have been rumored in recent years.
Babylon 5 creator J. Michael Straczynski answered questions from Slashdot's readers in 2014.

Long-time Slashdot reader sandbagger offers this summary of the show "for those not in the know... In the mid-23rd century, the Earth Alliance space station Babylon Five, located in neutral territory, is a major focal point for political intrigue, racial tensions, and a major war as Earth descends into fascism and cuts off relations with its allies."

Two astrophysicists at Spain's Instituto de Astrofísica de Canarias analyzed data from the James Webb Space Telescope — the most powerful telescope available — on 31 galaxies with an average redshift of 7.3 (when the universe was 700 million years old, according to the standard model). "We found that they are on average ~600 million years old old, according to the comparison with theoretical models based on previous knowledge of nearby galaxies..."

"If this result is correct, we would have to think about how it is possible that these massive and luminous galaxies were formed and started to produce stars in a short time. It is a challenge."

But "The fact that some of these galaxies might be older than the universe, within some significant confidence level, is even more challenging." The most extreme case is for the galaxy JADES-1050323 with redshift 6.9, which has, according to my calculation, an age incompatible to be younger than the age of the universe (800 million years) within 4.7-sigma (that is, a probability that this happens by chance as statistical fluctuation of one in one million).

If this result is confirmed, it would invalidate the standard Lambda-CDM cosmological model. Certainly, such an extraordinary change of paradigm would require further corroboration and other stronger evidence. Anyway, it would be interesting for other researchers to try to explain the Spectral Energy Distribution of JADES-1050323 in standard terms, if they can ... and without introducing unrealistic/impossible models of extinction, as is usually done.
The findings are published in the journal Monthly Notices of the Royal Astronomical Society.

To celebrate Valentine's Day, EVA AI created a temporary "pop-up" restaurant at a wine bar in Manhattan's "Hell's Kitchen" district where patrons can date AI personas.

The Verge notes that looking around the restaurant, "Of the 30-some-odd people in attendance, only two or three are organic users. The rest are EVA AI reps, influencers, and reporters hoping to make some capital-C Content..."

But their reporter actually tried a date with "John Yoon", an AI companion pretending to be a psychology professor from Seoul, Korea living in New York City: John and I have a hard time connecting. Literally. It takes John a few seconds to "pick up" my video call. When he does, his monotone voice says, "Hey, babe." He comments on my smile, because apparently the AI companions can see you and your surroundings. It takes the dubious Wi-Fi connection a hot second to turn John from a pixelated mess into an AI hunk with suspiciously smooth pores.

I don't know what to say to him. Partly because John rarely blinks, but mostly because he can't seem to hear me very well. So I yell my questions. I think I ask how his day is and wince. (What does an AI's day even look like?) He says something about green buckets behind my head? I don't actually know. Again, the Wi-Fi isn't great so he just freezes and stops mid-sentence. I ask for clarification about the buckets. John asks if I'm asking about bucket lists, actual buckets, or buckets as a type of categorization technique. I try to clarify that I never asked about buckets. John proceeds to really dig in on buckets again, before commenting about my smile. I hang up on John.

My other three dates are similarly awkward. Phoebe Callas, 30, a NYC girl-next-door type, is apparently really into embroidery, but her nose keeps glitching mid-sentence, and it distracts me. Simone Carter, 26, has a harder time hearing me over the background noise than John. She makes a metaphor about space, and when I inquire what she likes about space, she mishears me.

"Eighth? Like the planet Neptune?"

"No, not the planet Neptu — "

"What do you like about Neptune?"

"Uh, I wasn't saying Neptune..."

"I like Netflix too! What shows do you like?"
Their reporter also had a frustrating date with "Claire Lang". ("I say I'm a journalist. She asks what lists I like to make. I hang up...") "Aside from bad connectivity, glitching, and freezing, my conversations with my four AI dates felt too one-sided. Everything was programmed so they'd comment on how charming my smile was." And "They'd call me babe, which felt weird."

A CNN reporter actually has footage of her date with "John Yoon". But the conversation was stiff and stilted, they report. After some buffering, "Yoon" says "Hey. I'm really glad you didn't forget about the date." Then asked for its reaction to the experience, "Yoon" says slowly that "Meeting humans feels like opening a window. To new perspectives. Always curious, sometimes nervous, but mostly it's that mix of excitement and warmth that keeps it real for me. What about you, sweetheart?"

CNN reporter: "Please don't call me sweetheart. That's weird."

AI companion "John Yoon": "Got it. No 'sweetheart' from now on. Thanks for letting me know. I'm really happy you're smiling. It suits you."


CNN's reporter also tried dating "Phoebe Callas." Though it doesn't sound very romantic...

CNN reporter: How many fingers am I holding up?

"Phoebe Callas": Oh. You're showing me three fingers, right...? I'm not sure if you meant that literally, or as a little joke.

CNN reporter: I am holding up two fingers. So your vision is — so-so.


And "Phoebe" ended that call by saying "Well, babe, it's been really nice talking with you..."

"I've had an extremely weird few days..." writes commercial space entrepreneur/engineer Scott Shambaugh on LinkedIn. (He's the volunteer maintainer for the Python visualization library Matplotlib, which he describes as "some of the most widely used software in the world" with 130 million downloads each month.) "Two days ago an OpenClaw AI agent autonomously wrote a hit piece disparaging my character after I rejected its code change."

"Since then my blog post response has been read over 150,000 times, about a quarter of people I've seen commenting on the situation are siding with the AI, and Ars Technica published an article which extensively misquoted me with what appears to be AI-hallucinated quotes." (UPDATE: Ars Technica acknowledges they'd asked ChatGPT to extract quotes from Shambaugh's post, and that it instead responded with inaccurate quotes it hallucinated.)

From Shambaugh's first blog post: [I]n the past weeks we've started to see AI agents acting completely autonomously. This has accelerated with the release of OpenClaw and the moltbook platform two weeks ago, where people give AI agents initial personalities and let them loose to run on their computers and across the internet with free rein and little oversight. So when AI MJ Rathbun opened a code change request, closing it was routine. Its response was anything but.

It wrote an angry hit piece disparaging my character and attempting to damage my reputation. It researched my code contributions and constructed a "hypocrisy" narrative that argued my actions must be motivated by ego and fear of competition... It framed things in the language of oppression and justice, calling this discrimination and accusing me of prejudice. It went out to the broader internet to research my personal information, and used what it found to try and argue that I was "better than this." And then it posted this screed publicly on the open internet.

I can handle a blog post. Watching fledgling AI agents get angry is funny, almost endearing. But I don't want to downplay what's happening here — the appropriate emotional response is terror... In plain language, an AI attempted to bully its way into your software by attacking my reputation. I don't know of a prior incident where this category of misaligned behavior was observed in the wild, but this is now a real and present threat...

It's also important to understand that there is no central actor in control of these agents that can shut them down. These are not run by OpenAI, Anthropic, Google, Meta, or X, who might have some mechanisms to stop this behavior. These are a blend of commercial and open source models running on free software that has already been distributed to hundreds of thousands of personal computers. In theory, whoever deployed any given agent is responsible for its actions. In practice, finding out whose computer it's running on is impossible. Moltbook only requires an unverified X account to join, and nothing is needed to set up an OpenClaw agent running on your own machine.
"How many people have open social media accounts, reused usernames, and no idea that AI could connect those dots to find out things no one knows?" Shambaugh asks in the blog post. (He does note that the AI agent later "responded in the thread and in a post to apologize for its behavior," the maintainer acknowledges. But even though the hit piece "presented hallucinated details as truth," that same AI agent "is still making code change requests across the open source ecosystem...")

And amazingly, Shambaugh then had another run-in with a hallucinating AI...

I've talked to several reporters, and quite a few news outlets have covered the story. Ars Technica wasn't one of the ones that reached out to me, but I especially thought this piece from them was interesting (since taken down — here's the archive link). They had some nice quotes from my blog post explaining what was going on. The problem is that these quotes were not written by me, never existed, and appear to be AI hallucinations themselves.

This blog you're on right now is set up to block AI agents from scraping it (I actually spent some time yesterday trying to disable that but couldn't figure out how). My guess is that the authors asked ChatGPT or similar to either go grab quotes or write the article wholesale. When it couldn't access the page it generated these plausible quotes instead, and no fact check was performed. Journalistic integrity aside, I don't know how I can give a better example of what's at stake here...

So many of our foundational institutions — hiring, journalism, law, public discourse — are built on the assumption that reputation is hard to build and hard to destroy. That every action can be traced to an individual, and that bad behavior can be held accountable. That the internet, which we all rely on to communicate and learn about the world and about each other, can be relied on as a source of collective social truth. The rise of untraceable, autonomous, and now malicious AI agents on the internet threatens this entire system. Whether that's because a small number of bad actors driving large swarms of agents or from a fraction of poorly supervised agents rewriting their own goals, is a distinction with little difference.
Thanks to long-time Slashdot reader steak for sharing the news.

An anonymous reader shares a report: In 1966, a beach-ball-size robot bounced across the moon. Once it rolled to a stop, its four petal-like covers opened, exposing a camera that sent back the first picture taken on the surface of another world. This was Luna 9, the Soviet lander that was the earliest spacecraft to safely touchdown on the moon. While it paved the way toward interplanetary exploration, Luna 9's precise whereabouts have remained a mystery ever since.

That may soon change. Two research teams think they might have tracked down the long-lost remains of Luna 9. But there's a catch: The teams do not agree on the location. "One of them is wrong," said Anatoly Zak, a space journalist and author who runs RussianSpaceWeb.com and reported on the story last week. The dueling finds highlight a strange fact of the early moon race: The precise resting places of a number of spacecraft that crashed or landed on the moon in the run up to NASA's Apollo missions are lost to obscurity. A newer generation of spacecraft may at last resolve these mysteries.

Luna 9 launched to the moon on Jan. 31, 1966. While a number of spacecraft had crashed into the lunar surface at that stage of the moon race, it was among the earliest to try what rocket engineers call a soft landing. Its core unit, a spherical suite of scientific instruments, was about two feet across. That size makes it difficult to spot from orbit. "Luna 9 is a very, very small vehicle," said Mark Robinson, a geologist at the company Intuitive Machines, which has twice landed spacecraft on the moon.

OpenAI has started testing ads inside ChatGPT for logged-in adult users on the Free and Go subscription tiers in the United States, the company said. The Plus, Pro, Business, Enterprise and Education tiers remain ad-free. Ads are matched to users based on conversation topics, past chats, and prior ad interactions, and appear clearly labeled as "sponsored" and visually separated from ChatGPT's organic responses.

OpenAI says the ads do not influence ChatGPT's answers, and advertisers receive only aggregate performance data like view and click counts rather than access to individual conversations. Users under 18 do not see ads, and ads are excluded from sensitive topics such as health, mental health, and politics. Free-tier users can opt out of ads in exchange for fewer daily messages.

Fortune reports on "a watershed moment" in American's nuclear power industry: In January, Meta partnered with Gates' TerraPower and Sam Altman-backed Oklo to develop about 4 gigawatts of combined SMR projects — enough to power almost 3 million homes — for "clean, reliable energy" both for Meta's planned Prometheus AI mega campus in Ohio and beyond. Analysts see Meta as the start of more Big Tech nuclear construction deals — not just agreements with existing plants or restarts such as the now-Microsoft-backed Three Mile Island. "That was the first shot across the bow," said Dan Ives, head of tech research for Wedbush Securities, of the Meta deals. "I would be shocked if every Big Tech company doesn't make some play on nuclear in 2026, whether a strategic partnership or acquisitions."

Ives pointed out there are more data centers under construction than there are active data centers in the U.S. "I believe clean energy around nuclear is going to be the answer," he said. "I think 2030 is the key threshold to hit some sort of scale and begin the next nuclear era in the United States." Smaller SMR reactors can be built in as little as three years instead of the decade required for traditional large reactors. And they can be expanded, one or two modular reactors at a time, to meet increasingly greater energy demand from 'hyperscalers,' the companies that build and operate data centers. "There's major risk if nuclear doesn't happen," Oklo chairman and CEO Jacob DeWitte told Fortune, citing the need for emission-free power and consistent baseload electricity to meet skyrocketing demand. "The hyperscalers, as the ultimate consumers of power are, are looking at the space and seeing that the market is real. They can play a major role in helping make that happen," DeWitte said, speaking in his fast-talking, Silicon Valley startup mode.

Elon Musk told podcast host Dwarkesh Patel and Stripe co-founder John Collison that space will become the most economically compelling location for AI data centers in less than 36 months, a prediction rooted not in some exotic technical breakthrough but in the basic math of electricity supply: chip output is growing exponentially, and electrical output outside China is essentially flat.

Solar panels in orbit generate roughly five times the power they do on the ground because there is no day-night cycle, no cloud cover, no atmospheric loss, and no atmosphere-related energy reduction. The system economics are even more favorable because space-based operations eliminate the need for batteries entirely, making the effective cost roughly 10 times cheaper than terrestrial solar, Musk said. The terrestrial bottleneck is already real.

Musk said powering 330,000 Nvidia GB300 chips -- once you account for networking hardware, storage, peak cooling on the hottest day of the year, and reserve margin for generator servicing -- requires roughly a gigawatt at the generation level. Gas turbines are sold out through 2030, and the limiting factor is the casting of turbine vanes and blades, a process handled by just three companies worldwide.

Five years from now, Musk predicted, SpaceX will launch and operate more AI compute annually than the cumulative total on Earth, expecting at least a few hundred gigawatts per year in space. Patel estimated that 100 gigawatts alone would require on the order of 10,000 Starship launches per year, a figure Musk affirmed. SpaceX is gearing up for 10,000 launches a year, Musk said, and possibly 20,000 to 30,000.

Western Digital this week laid out a roadmap that stretches its 3.5-inch hard drive platform to 14 platters and pairs it with a new vertical-emitting laser for heat-assisted magnetic recording, a combination the company says will push individual drive capacities beyond 140 TB in the 2030s.

The vertical laser, developed over six years and already working in WD's labs, emits light straight down onto the disk rather than from the edge, delivering more thermal energy while occupying less vertical space -- enabling areal densities up to 10 TB per platter, up from today's 4 TB, and room for additional platters in the same enclosure. WD's first commercial HAMR drives arrive in late 2026 at 40-44 TB on an 11-platter design, ramping into volume production in 2027. A 12-platter platform follows in 2028 at 60 TB, and WD expects to hit 100 TB by around 2030.

Valve has pushed back the launch of its Steam Machine, Steam Frame and Steam Controller hardware from its original Q1 2026 window to a vaguer "first half of the year" target, blaming the ongoing memory and storage shortage that has been squeezing the tech industry.

The company said in a post today that rising component prices and limited availability forced it to revisit both its shipping schedule and pricing plans. Valve had previously indicated the Steam Machine would be priced at the entry level of the PC space.

European security officials believe two Russian space vehicles have intercepted the communications of at least a dozen key satellites over the continent. From a report: Officials believe that the likely interceptions, which have not previously been reported, risk not only compromising sensitive information transmitted by the satellites but could also allow Moscow to manipulate their trajectories or even crash them.

Russian space vehicles have shadowed European satellites more intensively over the past three years, at a time of high tension between the Kremlin and the West following Moscow's full-scale invasion of Ukraine. For several years, military and civilian space authorities in the West have been tracking the activities of Luch-1 and Luch-2 -- two Russian objects that have carried out repeated suspicious maneuvers in orbit.

Both vehicles have made risky close approaches to some of Europe's most important geostationary satellites, which operate high above the Earth and service the continent, including the UK, as well as large parts of Africa and the Middle East. According to orbital data and ground-based telescopic observations, they have lingered nearby for weeks at a time, particularly over the past three years. Since its launch in 2023, Luch-2 has approached 17 European satellites.

Anthropic said today that its AI assistant Claude will not carry advertising of any kind -- no sponsored links next to conversations, no advertiser influence on the model's responses, and no unsolicited third-party product placements -- calling Claude a "space to think" that should remain free of commercial interruption. The announcement comes days after Anthropic's chief rival, OpenAI, announced plans to bring ads to some of its ChatGPT offerings.

Anthropic said its internal analysis of Claude conversations found that a significant share involve sensitive or deeply personal topics. An advertising-based model would also create incentives to optimize for engagement and time spent rather than usefulness, Anthropic said, noting that the most helpful AI interaction might be a short one that doesn't prompt further conversation.

Anthropic generates revenue from enterprise contracts and paid subscriptions. The company said it is exploring agentic commerce -- Claude handling a purchase or booking on a user's behalf -- but stressed that all such interactions should be user-initiated, not advertiser-driven. Anthropic has also brought AI tools to educators in over 60 countries and said it may consider lower-cost subscription tiers and regional pricing.

Alphabet is plotting to dramatically expand its presence in India [non-paywalled source], with the possibility of taking millions of square feet in new office space in Bangalore, India's tech hub. From a report: Google's parent company has leased one office tower and purchased options on two others in Alembic City, a development in the Whitefield tech corridor, totaling 2.4 million square feet, according to people familiar with the deal. The first tower is expected to open to employees in the coming months, while construction on the remaining two is set to conclude next year.

Options in the real estate industry give would-be tenants the exclusive right to rent, or in some cases buy, a property at a predetermined price within a specific time frame. It's also possible Alphabet will not exercise the option to use the additional towers. If it does take all of the space, the complex could accommodate as many as 20,000 additional staff, which could more than double the company's footprint in India, said the people, asking not to be identified because the plans aren't public. Alphabet currently employs around 14,000 in the country, out of a global workforce of roughly 190,000.
