An anonymous reader quotes a report from Ars Technica: The first flight of Isar Aerospace's Spectrum rocket didn't last long on Sunday. The booster's nine engines switched off as the rocket cartwheeled upside-down and fell a short distance from its Arctic launch pad in Norway, punctuating the abbreviated test flight with a spectacular fiery crash into the sea. If officials at Isar Aerospace were able to pick the outcome of their first test flight, it wouldn't be this. However, the result has precedent. The first launch of SpaceX's Falcon 1 rocket in 2006 ended in similar fashion. "Today, we know twice as much about our launch system as yesterday before launch," Daniel Metzler, Isar's co-founder and CEO, wrote on X early Monday. "Can't beat flight testing. Ploughing through lots of data now."

Isar Aerospace, based in Germany, is the first in a crop of new European rocket companies to attempt an orbital launch. If all went according to plan, Isar's Spectrum rocket would have arced to the north from Andoya Spaceport in Norway and reached a polar orbit. But officials knew there was only a low chance of reaching orbit on the first flight. For this reason, Isar did not fly any customer payloads on the Spectrum rocket, designed to deliver up to 2,200 pounds (1,000 kilograms) of payload mass to low-Earth orbit. [...] Isar declared the launch a success in its public statements, but was it? [...] Metzler, Isar's chief executive, was asked last year what he would consider a successful inaugural flight of Spectrum. "For me, the first flight will be a success if we don't blow up the launch site," he said at the Handelsblatt innovation conference. "That would probably be the thing that would set us back the most in terms of technology and time."

This tempering of expectations sounds remarkably similar to statements made by Elon Musk about SpaceX's first flight of the Starship rocket in 2023. By this measure, Isar officials can be content with Sunday's result. The company is modeling its test strategy on SpaceX's iterative development cycle, where engineers test early, make fixes, and fly again. This is in stark contrast to the way Europe has traditionally developed rockets. The alternative to Isar's approach could be to "spend 15 years researching, doing simulations, and then getting it right the first time," Metzler said. With the first launch of Spectrum, Isar has tested the rocket. Now, it's time to make fixes and fly again. That, Isar's leaders argue, will be the real measure of success. "We're super happy," Metzler said in a press call after Sunday's flight. "It's a time for people to be proud of, and for Europe, frankly, also to be proud of."

The Washington Post reports that after months of polar darkness, the extent of sea ice blanketing the Arctic this winter "fell to the lowest level on record, researchers announced this week... the smallest maximum extent in the 47-year satellite record, according to the National Snow and Ice Data Center.

"Since then, the ice has already begun to melt again." "Sea ice is acting like the old canary in the coal mine," Dartmouth University geophysicist Don Perovich said. "It's saying loud and clear that warming is occurring...."

In the summer, when the sun's radiation shines down on the Arctic for 24 hours a day, the ice acts as a shield, reflecting more than half of the light that hits it back into space.... With so little sea ice in the Arctic this year, more sunlight will be able to reach the open ocean, which absorbs more than 90 percent of the radiation that hits it. This will further warm the region, accelerating ice melt and exposing even more water to the light. This feedback loop helps explain the rapid warming of the Arctic, and it is expected to lead to a complete lack of summer sea ice in the region within decades, [said explained Melinda Webster, a sea ice scientist at the University of Washington]. The consequences would be dire for seals, polar bears and other wildlife, which depend on a stable sea ice platform to birth their young and hunt for food. It would also expose miles of coastline to pounding ocean waves, accelerating the erosion that threatens to tip some communities into the sea.

But the effects will also be felt in places far from the poles, Perovich said. Studies suggest that a complete loss of Arctic sea ice would raise global temperatures as much as adding a trillion tons of carbon dioxide to the atmosphere. Changes in the Arctic could also affect the jet stream, the river of winds that flows through the upper atmosphere, contributing to more extreme weather around the globe.

"What happens in the Arctic doesn't stay in the Arctic," Perovich said.
Earlier this year sea ice also fell 30% below the amount typical in the Antarctic prior to 2010, the researchers report. The total amount of sea ice on earth has now reached an all-time low, declining by more than a million square miles (2.5 million square kilometers) below the pre-2010 average.

"Altogether, Earth is missing an area of sea ice large enough to cover the entire continental United States east of the Mississippi."

A new study warns that toxic Martian dust contains fine particles and harmful substances like silica and metals that pose serious health risks to astronauts, making missions to Mars more dangerous than previously thought. The Guardian reports: During Apollo missions to the moon, astronauts suffered from exposure to lunar dust. It clung to spacesuits and seeped into the lunar landers, causing coughing, runny eyes and irritated throats. Studies showed that chronic health effects would result from prolonged exposure. Martian dust isn't as sharp and abrasive as lunar dust, but it does have the same tendency to stick to everything, and the fine particles (about 4% the width of a human hair) can penetrate deep into lungs and enter the bloodstream. Toxic substances in the dust include silica, gypsum and various metals.

"A mission to Mars does not have the luxury of rapid return to Earth for treatment," the researchers write in the journal GeoHealth. And the 40-minute communication delay will limit the usefulness of remote medical support from Earth. Instead, the researchers stress that limiting exposure to dust is essential, requiring air filters, self-cleaning space suits and electrostatic repulsion devices, for example.

As NASA faces potential budget cuts, China is unveiling an ambitious series of deep space missions -- including Mars sample returns, outer planet exploration, and a future Mars base. While some of China's plans are aspirational, their track record of successful missions lends credibility to their expanding role in space. Ars Technica reports: China created a new entity called the "Deep Space Exploration Laboratory" three years ago to strengthen the country's approach to exploring the Solar System. Located in eastern China, not far from Shanghai, the new laboratory represented a partnership between China's national space agency and a local public college, the University of Science and Technology of China.

Not much is known outside of China about the laboratory, but it has recently revealed some very ambitious plans to explore the Solar System, including the outer planets. This week, as part of a presentation, Chinese officials shared some public dates about future missions. Space journalist Andrew Jones, who tracks China's space program, shared some images with a few details. Among the planned missions are:

- 2028: Tianwen-3 mission to collect samples of Martian soil and rocks and return them to Earth
- 2029: Tianwen-4 mission to explore Jupiter and its moon Callisto
- 2030: Development of a large, ground-based habitat to simulate long-duration human spaceflight
- 2033: Mission to Venus that will return samples of its atmosphere to Earth
- 2038: Establishment of an autonomous Mars research station to study in-situ resource utilization
- 2039: Mission to Triton, Neptune's largest moon, with a subsurface explorer for its ocean

Anthropic researchers have developed a breakthrough "cross-layer transcoder" (CLT) that functions like an fMRI for large language models, mapping how they process information internally. Testing on Claude 3.5 Haiku, researchers discovered the model performs longer-range planning for specific tasks -- such as selecting rhyming words before constructing poem sentences -- and processes multilingual concepts in a shared neural space before converting outputs to specific languages.

The team also confirmed that LLMs can fabricate reasoning chains, either to please users with incorrect hints or to justify answers they derived instantly. The CLT identifies interpretable feature sets rather than individual neurons, allowing researchers to trace entire reasoning processes through network layers.

U.S. robotics companies, including Tesla and Boston Dynamics, are urging lawmakers to establish a national robotics strategy to keep pace with China's aggressive investment in AI-driven robotics. The Associated Press reports: Jeff Cardenas, co-founder and CEO of humanoid startup Apptronik, of Austin, Texas, pointed out to lawmakers that it was American carmaker General Motors that deployed the first industrial robot at a New Jersey assembly plant in 1961. But the U.S. then ceded its early lead to Japan, which remains a powerhouse of industrial robotics, along with Europe. The next robotics race will be powered by artificial intelligence and will be "anybody's to win," Cardenas said in an interview after the closed-door meeting. "I think the U.S. has a great chance of winning. We're leading in AI, and I think we're building some of the best robots in the world. But we need a national strategy if we're going to continue to build and stay ahead."

The Association for Advancing Automation said a national strategy would help U.S. companies scale production and drive the adoption of robots as the "physical manifestation" of AI. The group made it clear that China and several other countries already have a plan in place. Without that leadership, "the U.S. will not only lose the robotics race but also the AI race," the association said in a statement. The group also suggested tax incentives to help drive adoption, along with federally-funded training programs and funding for both academic research and commercial innovation. A new federal robotics office, the association argued, is necessary partly because of "the increasing global competition in the space" as well as the "growing sophistication" of the technology.

The U.S. Space Force has certified United Launch Alliance's Vulcan Centaur rocket for national security missions after successful test flights and resolution of a booster nozzle issue. This certification allows ULA to join SpaceX in conducting launches under the National Security Space Launch program, with Vulcan missions expected to begin this summer. SpaceNews reports: "Thank you to all our customer partners who have worked hand-in-hand with us throughout this comprehensive certification process. We are grateful for the collaboration and excited to reach this critical milestone in Vulcan development," said Tory Bruno, president and chief executive of United Launch Alliance in a ULA statement about the vehicle's certification.

Bruno said at the roundtable that the next launch by ULA will be of its Atlas 5, carrying a set of Project Kuiper broadband satellites for Amazon. That launch is expected as soon as next month. He said then that would be followed by the first two Vulcan national security launches, missions designated USSF-106 and USSF-87. ULA did not give a schedule for those upcoming Vulcan launches but Space Systems Command, in a summary accompanying its press release, said the first NSSL mission on Vulcan is planned for the summer. Bruno said at the roundtable that the payloads for those missions have "complex processing" requirements beyond a typical mission, and did not state how long it would take them to be ready for a launch.

Bruno said ULA is projecting a dozen launches this year, split roughly evenly between Atlas and Vulcan and between national security and commercial missions. ULA has been stockpiling components, such as BE-4 engines and solid rocket boosters, needed for those missions. "We're all staged up and ready, and as spacecraft show up, we'll be able to fly them," he said. He noted the company wants to get to a "baseline tempo" of two launches a month by the end of this year and perform 20 launches next year.

RockDoctor (Slashdot reader #15,477) writes: A recent paper on ArXiv reports a novel idea about the central regions of "our" galaxy.

Remember the hoopla a few years ago about radio-astronomical observations producing an "image" of our central black hole — or rather, an image of the accretion disc around the black hole — long designated by astronomers as "Sagittarius A*" (or SGR-A*)? If you remember the image published then, one thing should be striking — it's not very symmetrical. If you think about viewing a spinning object, then you'd expect to see something with a "mirror" symmetry plane where we would see the rotation axis (if someone had marked it). If anything, that published image has three bright spots on a fainter ring. And the spots are not even approximately the same brightness.

This paper suggests that the image we see is the result of the light (radio waves) from SGR-A* being "lensed" by another black hole, near (but not quite on) the line of sight between SGR-A* and us. By various modelling approaches, they then refine this idea to a "best-fit" of a black hole with mass around 1000 times the Sun, orbiting between the distance of the closest-observed star to SGR-A* ("S2" — most imaginative name, ever!), and around 10 times that distance. That's far enough to make a strong interaction with "S2" unlikely within the lifetime of S2 before it's accretion onto SGR-A*.)

The region around SGR-A* is crowded. Within 25 parsecs (~80 light years, the distance to Regulus [in the constellation Leo] or Merak [in the Great Bear]) there is around 4 times more mass in several millions of "normal" stars than in the SGR-A* black hole. Finding a large (not "super massive") black hole in such a concentration of matter shouldn't surprise anyone.

This proposed black hole is larger than anything which has been detected by gravitational waves (yet) ; but not immensely larger — only a factor of 15 or so. (The authors also anticipate the "what about these big black holes spiralling together?" question : quote "and the amplitude of gravitational waves generated by the binary black holes is negligible.")

Being so close to SGR-A*, the proposed black hole is likely to be moving rapidly across our line of sight. At the distance of "S2" it's orbital period would be around 26 years (but the "new" black hole is probably further out than than that). Which might be an explanation for some of the variability and "flickering" reported for SGR-A* ever since it's discovery.

As always, more observations are needed. Which, for SGR-A* are frequently being taken, so improving (or ruling out) this explanation should happen fairly quickly. But it's a very interesting, and fun, idea.

Science magazine reports: A strange-looking telescope that scanned the skies from a perch in northern Chile for 15 years has released its final data set: detailed maps of the infant universe showing the roiling clouds of hydrogen and helium gas that would one day coalesce into the stars and galaxies we see today.

The Atacama Cosmology Telescope is not the first to survey the cosmic microwave background (CMB), the light released 380,000 years after the Big Bang when the early universe's soup of particles formed atoms and space became transparent. But the data — posted as preprints online today — give researchers a new level of detail on the density of the gas clouds and how they were moving.
At the top of the page for Science's article is an image where different colors "show areas where the polarization of the CMB light — its direction of vibration — differ, revealing how gases first move tangentially around areas of higher density (orange) and later fall straight in (blue) under the influence of gravity."

Long-time Slashdot reader sciencehabit writes: Using the data, researchers tested how well the standard cosmological theory, known as lambda cold dark matter, described the universe at that time 13.8 billion years ago; it's a remarkably good fit, they conclude.
The article notes that "back in the Chilean desert," the Atacama Cosmology Telescope's successor, the Simons Observatory, has already taken its first image, and "will begin its even more detailed examination of the CMB in the coming months."

NASA is considering "closing its headquarters and scattering responsibilities among the states," reports Politico, citing two people familiar with the plan. "The proposal could affect up to 2,500 jobs and redistribute critical functions, including who manages space exploration and organizes major science missions." While much of the day-to-day work occurs at NASA's 10 centers, the Washington office plays a strategic role in lobbying for the agency's priorities in Congress, ensuring the White House supports its agenda and partnering with foreign countries on critical space projects. Some of the headquarter's offices might remain in Washington, the people said, but it's not clear which ones those would be or who would keep their jobs...

One of the biggest fallouts is the damage it could do to coordination among NASA leadership on pressing issues... It would also limit cooperation with international partners on space, which is often done through embassies in Washington. NASA works with foreign partners on a range of projects, including the International Space Station and returning to the moon. The European Space Agency, for example, plans to provide modules for Gateway, a lunar space station that is central to NASA's Artemis program to land American astronauts back on the moon... The agency also helps coordinate support from foreign nations for the Artemis accords, which set goals for transparency and data sharing — and help create a level of trust in an unregulated part of the universe.

But the reallocation could have some benefits. Such a move would bring headquarters employees closer to the processes they manage. And it would give legislative liaison staff a chance to interact with lawmakers in their districts. "You're probably getting a lot more time with [lawmakers] at the local center or hosting events in the state or district," said Tom Culligan, a longtime space lobbyist,, the space industry lobbyist.

This week the "Old Vintage Computing Research" blog published a 21,000-word exploration of the DEC PDP-11, the 16-bit minicomputer sold by Digital Equipment Corporation. Slashdot reader AndrewZX calls the blog post "an excellent deep dive" into the machine's history and capabilities "and the classic Venix UNIX that it ran." The blogger still owns a working 1984 DEC Professional 380, "a tank of a machine, a reasonably powerful workstation, and the most practical PDP-adjacent thing you can actually slap on a (large) desk."

But more importantly, "It runs PRO/VENIX, the only official DEC Unix option for the Pros." In that specific market it was almost certainly the earliest such licensed Unix (in 1983) and primarily competed against XENIX, Microsoft's dominant "small Unix," which first emerged for XT-class systems as SCO XENIX in 1984. You'd wonder how rogue processes could be prevented from stomping on each other in such systems when neither the Intel 8086/8088 nor the IBM PC nor the PC/XT had a memory management unit, and the answer was not to try and just hope for the best. It was for this reason that IBM's own Unix variant PC/IX, developed by Interactive Systems Corporation under contract as their intended AT&T killer, was multitasking but single-user since in such an architecture there could be no meaningful security guarantees...

One of Venix's interesting little idiosyncrasies, seen in all three Pro versions, was the SUPER> prompt when you've logged on as root (there is also a MAINT> prompt when you're single-user...

Although Bill Gates had been their biggest nemesis early on, most of the little Unices that flourished in the 1980s and early 90s met their collective demise at the hands of another man: Linus Torvalds. The proliferation of free Unix alternatives like Linux on commodity PC hardware caused the bottom to fall out of the commercial Unix market.
The blogger even found a 1989 log for the computer's one and only guest login session — which seems to consist entirely of someone named tom trying to exit vi.

But the most touching part of the article comes when the author discovers a file named /thankyou that they're certain didn't come with the original Venix. It's an ASCII drawing of a smiling face, under the words "THANK YOU FOR RESCUING ME".

"It's among the last files created on the system before it came into my possession..."

It's all a fun look back to a time when advances in semiconductor density meant microcomputers could do nearly as much as the more expensive minicomputers (while taking up less space) — leaving corporations pondering the new world that was coming: As far back as 1974, an internal skunkworks unit had presented management with two small systems prototypes described as a PDP-8 in a VT50 terminal and a portable PDP-11 chassis.

Engineers were intrigued but sales staff felt these smaller versions would cut into their traditional product lines, and [DEC president Ken] Olsen duly cancelled the project, famously observing no one would want a computer in their home.

Slashdot reader Required Snark shared this article from Phys.org: In the realm of science fiction, [sun-energy capturing] Dyson spheres and ringworlds have been staples for decades. But it is well known that the simplest designs are unstable against gravitational forces and would thus be torn apart. Now a scientist from Scotland, UK has shown that certain configurations of these objects near a two-mass system can be stable against such fractures...

[A] rigid ring around a star or planet, as in Larry Niven's "Ringworld" series of novels, is also unstable, as it would drift under any slight gravitational differences and collide with the star. So [engineering science professor Colin] McInnes considered a restricted three-body problem where two equal masses orbit each other circularly with a uniform ring of infinitesimal mass rotating in their orbital plane. The ring could enclose both masses, just one or none... McInnes also investigated a shell-restricted three-body problem with the shell also of infinitesimal mass, again with the shell enclosing two masses, one or none.

For the restricted ring, McInnes found that there are seven equilibrium points in the orbital plane of the dual masses, on which, if the ring's center were placed, it would stay and not experience stresses, akin to the three stable Lagrange points where a small mass can reside permanently for the two-body problem... McInnes restricted this research to a planar ring (in the plane of the circularly orbiting masses) but says it can be shown that a vertical ring, normal to the plane, can also generate equilibria...

These results can aid the search for extraterrestrial intelligence, McInnes said, "If we can understand when such structures can be stable, then this could potentially help direct future SETI surveys." An important technosignature would be one bright star orbiting in tandem with an object showing a strong infrared excess. Shells around a sun-exoplanet pair or an exoplanet-exoplanet pair could also be possible. A nested set of Dyson spheres is also a feasible geometry.
In 2003 Ringworld author Larry Niven answered questions from Slashdot readers...

Apple's latest iOS 18.3.2 update is automatically re-enabling its Apple Intelligence feature even for users who previously disabled it, adding to mounting concerns about the company's AI strategy.

The update presents a splash screen with no option except to tap "Continue," which activates the feature. Users must then manually disable it through settings, with the AI consuming up to 7GB of storage space. This forced activation comes amid broader troubles with Apple's AI initiatives.

Cosmologists have uncovered stronger evidence that dark energy -- the mysterious force accelerating cosmic expansion -- may be weakening over time. The Dark Energy Spectroscopic Instrument (DESI) collaboration presented their latest findings at the Global Physics Summit in Anaheim, California, reinforcing their preliminary results from last year.

The DESI team analyzed data from approximately 15 million galaxies collected over three years, more than doubling their previous dataset of 6 million galaxies. Combined with supernova observations and cosmic microwave background data, their analysis shows a 4.2-sigma deviation from the standard Lambda-CDM cosmological model, which assumes dark energy remains constant.

"We are much more certain than last year that this is definitely a thing," said Seshadri Nadathur of the University of Portsmouth, a key DESI researcher. These findings align with recent independent results from the Dark Energy Survey (DES), which earlier this month reported a similar 3.2-sigma tension with Lambda-CDM -- a tension that disappears if dark energy is allowed to vary. If confirmed, evolving dark energy could fundamentally alter cosmologists' understanding of the universe's ultimate fate. Instead of expanding indefinitely until all particles become impossibly separated, the universe might follow alternative trajectories.

"It challenges the fate of the universe," explained Mustapha Ishak-Boushaki from the University of Texas at Dallas. "It's game-changing." Moreover, these findings challenge the simplest explanation of dark energy as vacuum energy, which quantum physics suggests should remain constant. Instead, the results indicate unknown physics, possibly involving a new particle, a modification to Einstein's theory of gravity, or even a new fundamental theory. DESI will continue observing through 2026, eventually producing a final map expected to include 50 million galaxies, potentially providing definitive evidence for this cosmic paradigm shift.

NASA's SpaceX Crew-9 has returned to Earth safely after a stay of more than nine months aboard the International Space Station. The crew remained in space longer than expected due to issues with Boeing's Starliner capsule, which was originally scheduled to bring them home sooner.

While the mission has been politically fraught, the astronauts said in a rare space-to-earth interview last month that they were neither stranded nor abandoned. "That's been the rhetoric. That's been the narrative from day one: stranded, abandoned, stuck -- and I get it. We both get it," [NASA astronaut Butch] Wilmore said. "But that is, again, not what our human spaceflight program is about. We don't feel abandoned, we don't feel stuck, we don't feel stranded." Wilmore added a request: "If you'll help us change the rhetoric, help us change the narrative. Let's change it to 'prepared and committed.' That's what we prefer..." CNN has more details on the arrival: Williams and Wilmore, alongside NASA's Nick Hague and cosmonaut Aleksandr Gorbunov of Russia's Roscosmos space agency, safely splashed down off the coast of Tallahassee, Florida at 5:57 p.m. ET. The crew's highly anticipated return came after the crew climbed aboard a SpaceX Crew Dragon capsule and departed the International Space Station at 1:05 a.m. ET. Williams, Wilmore, Hague and Gorbunov spent Tuesday morning and afternoon in orbit in the roughly 13-foot-wide (4-meter-wide), gumdrop-shaped SpaceX Crew Dragon spacecraft. Gradually descending, the capsule carried the astronauts from the space station, which orbits about 250 miles (400 kilometers) above Earth, toward the thick inner layer of our planet's atmosphere.

Around 5 p.m. ET, the Crew Dragon capsule began firing its engines to begin the final phase of the journey: reentry. This leg of the journey is considered the most dangerous of any flight home from space. The jarring physics of hitting the atmosphere while traveling more than 22 times the speed of sound routinely heats the exterior of returning spacecraft to more than 3,500 degrees Fahrenheit (1,926 degrees Celsius) and can trigger a communication blackout. After plunging toward home, the Crew Dragon spacecraft deployed two sets of parachutes in quick succession to further slow its descent. The capsule decelerated from orbital speeds of more than 17,000 miles per hour (27,359 kilometers per hour) to less than 20 miles per hour (32 kilometers per hour) as the vehicle hit the ocean.

After the vehicle hit the ocean, a SpaceX rescue ship waiting nearby worked to haul the spacecraft out of the water. Williams and Wilmore and their crewmates will soon exit Dragon and take their first breaths of earthly air in nine months. Medical teams will evaluate the crew's health, as is routine after astronauts return from space, before deciding next steps. Ultimately, the NASA crew members will return to their home base at Johnson Space Center in Houston. You can watch a recording of the re-entry and splashdown here.

Zillow CEO Jeremy Wacksman "recently told Entrepreneur magazine that almost five years of remote work has 'been fantastic for us,'" writes the Seattle Times. Zillow shifted to allowing people to work fully remote during the pandemic. It's been a recruiting and retention tool for Zillow as they "now see four times the number of job applicants for every job we have versus what we did before the pandemic," Wacksman said.

While Zillow still lists its corporate headquarters as Seattle, the company bills itself as "cloud-headquartered," with remote workers and satellite offices. Wacksman's comments are backed by serious real estate moves the company has made over the past five years. An annual report detailing Zillow's financial results for 2024 shows its Seattle headquarters and offices across the country are shrinking. In 2019, Zillow had 386,275 square feet of office space in Seattle after steadily gobbling up floors of the Russell Investments Center downtown over the prior five years. The company reported it had 113,470 square feet in Seattle at the end of 2024... The company has drastically cut costs by shedding offices. Zillow's total leasing costs reached $54 million in 2022 and dropped to $34 million last year... It expects those costs to decrease even further, to $18 million by 2029. Zillow is also taking advantage of subleasing some of its office space and expects $26 million in sublease income between 2025 and 2030...

Zillow's financial results from last year suggest the workforce has been productive while logging in from home. The company reported Tuesday that it beat Wall Street expectations for the last three months of 2024 with a quarterly revenue of $554 million. Wacksman said in a news release Tuesday that 2024 was a "remarkable year for Zillow," as it reached its goal of double-digit revenue growth.

Intel's stock jumped nearly 19% this week. "However, in the past year through Wednesday's close, Intel stock had fallen 53%," notes Investor's Business Daily: The appointment of Lip-Bu Tan as CEO is a "good start" but Intel has significant challenges, Morgan Stanley analyst Joseph Moore said in a client note. Those challenges include delays in its server chip product line, a very competitive PC chip market, lack of a compelling AI chip offering, and over $10 billion in losses in its foundry business over the past 12 months. There is "no quick fix" for those issues, he said.
"There are things you can do," a Columbia business school associate professor tells the Wall Street Journal in a video interview, "but it's going to be incremental, and it's going to be extremely risky... They will try to be competitive in the foundry manufacturing space," but "It takes very aggressive investments."

Meanwhile, TSMC is exploring a joint venture where they'd operate Intel's factories, even pitching the idea to AMD, Nvidia, Broadcam, and Qualcomm, according to Reuters. (They add that Intel "reported a 2024 net loss of $18.8 billion, its first since 1986," and talked to multiple sources "familiar with" talks about Intel's future). Multiple companies have expressed interest in buying parts of Intel, but two of the four sources said the U.S. company has rejected discussions about selling its chip design house separately from the foundry division. Qualcomm has exited earlier discussions to buy all or part of Intel, according to those people and a separate source. Intel board members have backed a deal and held negotiations with TSMC, while some executives are firmly opposed, according to two sources.
"They say Lip-Bu Tan is the best hope to fix Intel — if Intel can be fixed at all," writes the Wall Street Journal: He brings two decades of semiconductor industry experience, relationships across the sector, a startup mindset and an obsession with AI...and basketball. He also comes with tricky China business relationships, underscoring Silicon Valley's inability to sever itself from one of America's top adversaries... [Intel's] stock has lost two-thirds of its value in four short years as Intel sat out the AI boom...

Manufacturing chips is an enormous expense that Intel can't currently sustain, say industry leaders and analysts. Former board members have called for a split-up. But a deal to sell all or part of Intel to competitors seems to be off the table for the immediate future, according to bankers. A variety of early-stage discussions with Broadcom, Qualcomm, GlobalFoundries and TSMC in recent months have failed to go anywhere, and so far seem unlikely to progress. The company has already hinted at a more likely outcome: bringing in outside financial backers, including customers who want a stake in the manufacturing business...

Tan has likely no more than a year to turn the company around, said people close to the company. His decades of investing in startups and running companies — he founded a multinational venture firm and was CEO of chip design company Cadence Design Systems for 13 years — provide indications of how Tan will tackle this task in the early days: by cutting expenses, moving quickly and trying to turn Intel back into an engineering-first company. "In areas where we are behind the competition, we need to take calculated risks to disrupt and leapfrog," Tan said in a note to Intel employees on Wednesday. "And in areas where our progress has been slower than expected, we need to find new ways to pick up the pace...."

Many take this culture reset to also mean significant cuts at Intel, which already shed about 15,000 jobs last year. "He is brave enough to adjust the workforce to the size needed for the business today," said Reed Hundt, a former Intel board member who has known Tan since the 1990s.

"For the first time in history, a privately operated lunar lander has captured images of a total eclipse from the Moon's surface," reports Daily Galaxy.

While the Athena lunar lander tipped over and ended its mission, elsewhere on the moon Firefly Aerospace's Blue Ghost lunar lander "continues to beam home incredible imagery," writes Space.com, and since its landing on March 2 "has been sending us stunning photos and videos..." A new video of Blue Ghost's moon-side view captures the eerie red light on the moon (caused by sunlight refracting through the atmosphere over the edges of the earth). "Blue Ghost turns red!" Firefly writes on their mission updates page.

A SpaceX photographer also captured the eclipse as it happened over a Falcon 9 rocket waiting to launch to the International Space Station, in a remarkable time-lapse photograph.

And Space.com collects more interesting lunar-eclipse photos taken from around the world, including Appin, Scotland; Canberra, Australia; and Palm Springs, California...

"SpaceX founder Elon Musk has said his Starship rocket will head to Mars by the end of next year," writes the BBC, "as the company investigates several recent explosions in flight tests." Human landings could begin as early as 2029 if initial missions go well, though "2031 was more likely", he added in a post on his social media platform X...

The billionaire said in 2020 that he remained confident that his company would land humans on Mars six years later. In 2024, he said he would launch the first Starships to Mars in 2026, with plans to send crewed flights in four years.

Musk has said that the coming Mars mission would carry the Tesla humanoid robot "Optimus", which was shown to the public last year.

"Is everything we see around us is sealed within a black hole?" asks Space.com.

Because here's the thing. The $10 billion James Webb Space telescope (in operation since 2022) "has found that the vast majority of deep space and, thus the early galaxies it has so far observed, are rotating in the same direction. While around two-thirds of galaxies spin clockwise, the other third rotates counter-clockwise." In a random universe, scientists would expect to find 50% of galaxies rotating one way, while the other 50% rotate the other way. This new research suggests there is a preferred direction for galactic rotation... "It is still not clear what causes this to happen, but there are two primary possible explanations," team leader Lior Shamir, associate professor of computer science at the Carl R. Ice College of Engineering, said in a statement. "One explanation is that the universe was born rotating.

"That explanation agrees with theories such as black hole cosmology, which postulates that the entire universe is the interior of a black hole.

"But if the universe was indeed born rotating, it means that the existing theories about the cosmos are incomplete." Black hole cosmology, also known as "Schwarzschild cosmology," suggests that our observable universe might be the interior of a black hole itself within a larger parent universe. The idea was first introduced by theoretical physicist Raj Kumar Pathria and by mathematician I. J. Good. It presents the idea that the "Schwarzchild radius," better known as the "event horizon," (the boundary from within which nothing can escape a black hole, not even light) is also the horizon of the visible universe.
The article cites a theory by Polish theoretical physicist Nikodem Poplawski of the University of New Haven that ultimately black holes don't compress indefinitely into a singularity. "The matter instead reaches a state of finite, extremely large density, stops collapsing, undergoes a bounce like a compressed spring, and starts rapidly expanding," Poplawski explained to Space.com... The scientist continued by adding that rapid recoil after such a big bounce could be what has led to our expanding universe, an event we now refer to as the Big Bang... "I think that the simplest explanation of the rotating universe is the universe was born in a rotating black hole."
Team leader Shamir offers another theory: that we just need to re-calibrate our distance measurements for the deep universe. (Which could also explain the difference in the expansion rates in the universe "and the large galaxies that according to the existing distance measurements are expected to be older than the universe itself.")
