La capsule Starliner est déjà depuis plus de trois semaines amarrée à la Station spatiale internationale, alors que la mission a duré à peine plus d’une semaine. En cause, des problèmes dont la cause première n’a toujours pas été identifiée. La NASA et Boeing ne savent toujours quand pas la capsule va pouvoir revenir sur Terre et la durée de la mission pourraient être prolongée.

Après des années de retard et des déboires de dernière minute, la capsule Starliner est finalement arrivée sur la Station spatiale internationale le 6 juin. Si l’arrimage est un succès, la NASA et Boeing ont détecté cinq fuites d‘hélium, même si les deux partenaires affirment que tout va bien.

Dans la capsule, se trouvaient Butch Wilmore et Suni Williams, qui ne devaient rester que huit à dix jours dans la Station spatiale internationale. Plus de trois semaines plus tard, ils sont toujours dans l‘ISS. « Je tiens à préciser très clairement que Butch et Suni ne sont pas bloqués dans l’espace », explique Steve Stich, responsable du programme des vols commerciaux de la NASA.

La question se pose, car le voyage dure bien plus longtemps que prévu, sans que l’on sache pourquoi. Aucune date de retour n’est programmée. Néanmoins, les responsables du programme affirment que les astronautes et la capsule pourraient quitter l‘ISS en cas d‘urgence.

« Une campagne d’essais débutera dès le 2 juillet au centre de White Sands au Nouveau-Mexique afin de reproduire la façon dont les propulseurs ont été utilisés pendant le vol […] Les tests prendront environ deux semaines, mais cela dépend de ce qui est trouvé – et d’autres analyses seront nécessaires par la suite », ajoute Steve Stich.

« Nous ne sommes pas pressés », martèle ce dernier avant d’ajouter que l’Agence spatiale européenne envisageait de « prolonger la durée maximale de la mission Starliner de 45 jours à 90 jours », ajoute CNN.

Il faut dire que les ingénieurs ne sont « toujours pas certains de la cause profonde des problèmes du Starliner ». En attendant, les deux astronomes Butch Wilmore et Suni Williams restent dans l’ISS et participent aux tâches de routine.

game of Asteroids An anonymous reader shared this report from The Hill: An asteroid the size of a football stadium threaded the needle between Earth and the moon Saturday morning — the second of two astronomical near misses in three days. Near miss, in this case, is a relative term: Saturday's asteroid, 2024 MK, came within 180,000 miles of Earth. On Thursday, meanwhile, asteroid 2011 UL21 flew within 4 million miles. But the Saturday passage of 2024 MK — which scientists discovered only two weeks ago — coincides with a sobering reminder of threats from space. Sunday is Asteroid Day, the anniversary of the 1908 explosion of a rock from space above a Russian town — the sort of danger that, astronomers warn, is always lurking as the Earth hurtles through space... In 2013, for instance, an asteroid about 62 feet across that broke apart nearly 20 miles above Siberia released 30 times as much energy as the atomic bomb that hit Hiroshima. While most of the impact energy was absorbed by the atmosphere, the detonation triggered a shock wave that blew out windows and injured more than a thousand people. The article points out that if Saturday's asteroid had hit earth, the impact would have "the equivalent impact energy in the hundreds of megaton approaching a gigaton," Peter Brown of Canada's Western University told the Canadian Broadcasting Service. (For comparison, most hydrogen bombs are in the 50-megaton range.) Brown said "It's the sort of thing that if it hit the east coast of the U.S., you would have catastrophic effects over most of the eastern seaboard. But it's not big enough to affect the whole world." Meanwhile, the article adds that last Thursday's asteroid — "while it was comfortably far out in space" — was the size of Mt. Everest. "At 1.5 miles in diameter, that asteroid was about a quarter the size of the asteroid that struck the earth 65 million years ago, wiping out all dinosaurs that walked, as well as the majority of life on earth." But the risk of a collision like that "is very, very low." NASA has estimated that a civilization-ending event (like the collision of an asteroid the size of Thursday's with the Earth) should only happen every few million years. And such an impact from an asteroid half a mile in diameter or bigger will be almost impossible for a very long time, according to findings published last year in The Astronomical Journal. NASA's catalog of large and dangerous objects like 2011 UL21 is now 95 percent complete, MIT Technology Review reported.

It's been adapted into a graphic novel, a videogame, a radio play, and an opera, according to Wikipedia — which also describes years of trying to adapt Neuromancer into a movie. "The landmark 1984 cyberpunk novel has been on Hollywood's wishlist for decades," writes Gizmodo, "with multiple filmmakers attempting to bring it to the big screen." (Back in 2010, Slashdot's CmdrTaco even posted an update with the headline "Neuromancer Movie In Your Future?" with a 2011 story promising the movie deal was "moving forward....") But now Deadline reports it's becoming a 10-episode series on Apple TV+ (co-produced by Apple Studios) starring Callum Turner and Brianna Middleton: Created for television by Graham Roland and JD Dillard, Neuromancer follows a damaged, top-rung super-hacker named Case (Turner) who is thrust into a web of digital espionage and high stakes crime with his partner Molly (Middleton), a razor-girl assassin with mirrored eyes, aiming to pull a heist on a corporate dynasty with untold secrets. More from Gizmodo: "We're incredibly excited to be bringing this iconic property to Apple TV+," Roland and Dillard said in a statement. "Since we became friends nearly 10 years ago, we've looked for something to team up on, so this collaboration marks a dream come true. Neuromancer has inspired so much of the science fiction that's come after it and we're looking forward to bringing television audiences into Gibson's definitive 'cyberpunk' world." The novel launched Gibson's "Sprawl" trilogy of novels (building on the dystopia in his 1982 short story "Burning Chrome"), also resurrecting the "Molly Millions" character from Johnny Mnemonic — an even earlier short story from 1981...

USENIX, the long-running OS/networking research group, also publishes a magazine called ;login:. Today the magazine's editor — security consultant Rik Farrow — stopped by Slashdot to share some new research. rikfarrow writes: Caching means using faster memory to store frequently requested data, and the most commonly used algorithm for determining which items to discard when the cache is full is Least Recently Used [or "LRU"]. These researchers have come up with a more efficient and scalable method that uses just a few lines of code to convert LRU to SIEVE. Just like a sieve, it sifts through objects (using a pointer called a "hand") to "filter out unpopular objects and retain the popular ones," with popularity based on a single bit that tracks whether a cached object has been visited: As the "hand" moves from the tail (the oldest object) to the head (the newest object), objects that have not been visited are evicted... During the subsequent rounds of sifting, if objects that survived previous rounds remain popular, they will stay in the cache. In such a case, since most old objects are not evicted, the eviction hand quickly moves past the old popular objects to the queue positions close to the head. This allows newly inserted objects to be quickly assessed and evicted, putting greater eviction pressure on unpopular items (such as "one-hit wonders") than LRU-based eviction algorithms. It's an example of "lazy promotion and quick demotion". Popular objects get retained with minimal effort, with quick demotion "critical because most objects are not reused before eviction." After 1559 traces (of 247,017 million requests to 14,852 million objects), they found SIEVE reduces the miss ratio (when needed data isn't in the cache) by more than 42% on 10% of the traces with a mean of 21%, when compared to FIFO. (And it was also faster and more scalable than LRU.) "SIEVE not only achieves better efficiency, higher throughput, and better scalability, but it is also very simple."

The Linux 6.10 kernel cycle continues trending along nominally and giving hope for an on-time stable kernel release in two weeks...

America's Justice Department "is pushing for Boeing to plead guilty to a criminal charge," reports Reuters, "after finding the planemaker violated a settlement over fatal 737 MAX crashes in 2018 and 2019 that killed 346 people, two people familiar with the matter said on Sunday." Boeing previously paid $2.5 billion as part of the deal with prosecutors that granted the company immunity from criminal prosecution over a fraud conspiracy charge related to the 737 MAX's flawed design. Boeing had to abide by the terms of the deferred prosecution agreement for a three-year period that ended on Jan. 7. Prosecutors would then have been poised to ask a judge to dismiss the fraud conspiracy charge. But in May, the Justice Department found Boeing breached the agreement, exposing the company to prosecution. A guilty plea could "carry implications for Boeing's ability to enter into government contracts," the article points out, "such as those with the U.S. military that make up a significant portion of its revenue..." The proposal would require Boeing to plead guilty to conspiring to defraud the U.S. Federal Aviation Administration in connection with the fatal crashes, the sources said. The proposed agreement also includes a $487.2 million financial penalty, only half of which Boeing would be required to pay, they added. That is because prosecutors are giving the company credit for a payment it made as part of the previous settlement related to the fatal crashes of the Lion Air and Ethiopian Airlines flights. Boeing could also likely be forced to pay restitution under the proposal's terms, the amount of which will be at a judge's discretion, the sources said. The offer also contemplates subjecting Boeing to three years of probation, the people said. The plea deal would also require Boeing's board to meet with victims' relatives and impose an independent monitor to audit the company's safety and compliance practices for three years, they said. "Should Boeing refuse to plead guilty, prosecutors plan to take the company to trial, they said..." the article points out. "Justice Department officials revealed their decision to victims' family members during a call earlier on Sunday."

A new study "has found direct evidence linking a key chemical ingredient of plastic bottles to a higher risk of type 2 diabetes," reports the Independent: The study, published in the journal Diabetes, found that the chemical BPA used to make food and drink packages, including plastic water bottles, can reduce sensitivity to the hormone insulin which regulates the body's sugar metabolism. The findings, to be presented at the 2024 Scientific Sessions of the American Diabetes Association, call for the US Environmental Protection Agency to reconsider the safe limits for exposure to BPA in bottles and food containers. Previous studies have already shown that the chemical Bisphenol A (BPA) used to make plastic and epoxy resins could disrupt hormones in humans. While research has linked BPA to diabetes, no previous study has directly assessed if administration of this chemical to humans increases this risk in adults. The researchers administered the dosage considered safe by America's FDA to about 20 individuals — and discovered they became less responsive to insulin after 4 days. The article includes this warning from the researchers: "These results suggest that maybe the U.S. EPA safe dose should be reconsidered and that healthcare providers could suggest these changes to patients." Thanks to Slashdot reader Bruce66423 for sharing the news.

To stop their smartphone battery from swelling, long-time Slashdot reader shanen bought a Samsung Galaxy with a "restrictive charging option." But what setting should they use? The way this battery protection option worked was to stop charging the phone at 85%. That left me enough charge for my normal daily travels, which rarely took the phone below 50%, and the battery remained unswollen after a year, which included a month of quite heavy tethering, too. Unfortunately... After a recent upgrade, now my Galaxy has three options for the battery where it had two. The 85% option is still there, but it has been lowered to 80%. I've been using that for now and it still seems good enough. However my main concern is with the best option to maximize the overall lifespan of the smartphone... The other old option says something about using AI to control the battery charging, but I don't trust it and think it is just the old approach that causes phones to die quickly... The new third option is the one that is interesting me. This seems to be a kind of flutter charge where the phone will charge to 100% and then stop until it has dropped to 95% before charging again, even if it remains plugged in. This sounds attractive and would give me more battery insurance when I'm traveling, but maybe it reduces the overall lifetime of the phone? They tried getting answers from Samsung, but "I think I have been flagged as a low-profit customer." And of course, this raises several other questions? (Are other smartphones better? Have iPhones solved the battery-swelling issue?) And most importantly: is there a way to charge batteries without reducing their lifespan? Share your own thoughts and experiences in the comments. What's the best way to charge your smartphone battery?

Commercial space efforts continue around the world, as the Chinese company Space Pioneer fired up a partially-fueled rocket engine Sunday for a short-duration test of its reusable rocket on the ground. But Space News reports that the test "ended in catastrophic failure and a dramatic explosion." "Amateur footage captured by Gongyi citizens and posted on Chinese social media shows the nine-engine test stage igntiing and then, exceptionally, taking off." Hold-down clamps and other structures are typically used to securely keep stages in place. The stage is seen climbing into the sky before halting, apparently with its engines shutting off, and returning to Earth. The stage impacted the ground around 50 seconds after it took off, apparently with much of its kerosene-liquid oxygen propellant remaining, causing a large explosion. The Tianlong-3 first stage would likely fire for a number of minutes on an orbital flight. Space Pioneer was conducting its test as a buildup to an orbital launch of the Tianlong-3, which is benchmarked against the SpaceX Falcon 9, in the coming months. The company announced earlier this month that it has secured $207 million in new funding. Shanghai-based digital newspaper The Paper reported Henan officials as saying there were no casualties reported. Space Pioneer issued its own statement later, stating there was a structural failure at the connection between the rocket body and the test bench. The rocket's onboard computer automatically shut down the engines and the rocket fell 1.5 kilometers southwest. It reiterated earlier reports that no casualties were found. The company said the test produced 820 tons of thrust. The article speculates on whether the event will delay the development of the rocket — or the planned launches for a Chinese megaconstellation of satellites. "Space Pioneer says it will conduct an analysis and restart testing with new hardware as soon as possible."

Bloomberg and The Washington Post "claim AI power usage is dire," writes Slashdot reader NoWayNoShapeNoForm. But Ars Technica "begs to disagree with those speculations." From Ars Technica's article: The high-profile pieces lean heavily on recent projections from Goldman Sachs and the International Energy Agency (IEA) to cast AI's "insatiable" demand for energy as an almost apocalyptic threat to our power infrastructure. The Post piece even cites anonymous "some [people]" in reporting that "some worry whether there will be enough electricity to meet [the power demands] from any source." Digging into the best available numbers and projections available, though, it's hard to see AI's current and near-future environmental impact in such a dire light... While the headline focus of both Bloomberg and The Washington Post's recent pieces is on artificial intelligence, the actual numbers and projections cited in both pieces overwhelmingly focus on the energy used by Internet "data centers" as a whole... Bloomberg asks one source directly "why data centers were suddenly sucking up so much power" and gets back a blunt answer: "It's AI... It's 10 to 15 times the amount of electricity." Unfortunately for Bloomberg, that quote is followed almost immediately by a chart that heavily undercuts the AI alarmism. That chart shows worldwide data center energy usage growing at a remarkably steady pace from about 100 TWh in 2012 to around 350 TWh in 2024. The vast majority of that energy usage growth came before 2022, when the launch of tools like Dall-E and ChatGPT largely set off the industry's current mania for generative AI. If you squint at Bloomberg's graph, you can almost see the growth in energy usage slowing down a bit since that momentous year for generative AI. Ars Technica first cites Dutch researcher Alex de Vries's estimate that in a few years the AI sector could use between 85 and 134 TWh of power. But another study estimated in 2018 that PC gaming already accounted for 75 TWh of electricity use per year, while "the IEA estimates crypto mining ate up 110 TWh of electricity in 2022." More to the point, de Vries' AI energy estimates are only a small fraction of the 620 to 1,050 TWh that data centers as a whole are projected to use by 2026, according to the IEA's recent report. The vast majority of all that data center power will still be going to more mundane Internet infrastructure that we all take for granted (and which is not nearly as sexy of a headline bogeyman as "AI"). The future is also hard to predict, the article concludes. "If customers don't respond to the hype by actually spending significant money on generative AI at some point, the tech-marketing machine will largely move on, as it did very recently with the metaverse and NFTs..."

It was analgous to the "Blue Screen of Death" that Windows gives for critical errors, Phoronix wrote. To enable error messages for things like a kernel panic, Linux 6.10 introduced a new panic handler infrastructure for "Direct Rendering Manager" (or DRM) drivers. Phoronix also published a follow-up from Red Hat engineer Javier Martinez Canillas (who was involved in the new DRM Panic infrastructure). Given complaints about being too like Microsoft Windows following his recent Linux "Blue Screen of Death" showcase... Javier showed that a black screen of death is possible if so desired... After all, it's all open-source and thus can customize to your heart's content. And now the panic handler is getting even more new features, Phoronix reported Friday: With the code in Linux 6.10 when DRM Panic is triggered, an ASCII art version of Linux's mascot, Tux the penguin, is rendered as part of the display. With Linux 6.11 it will also be able to handle displaying a monochrome image as the logo. If ASCII art on error messages doesn't satisfy your tastes in 2024+, the DRM Panic code will be able to support a monochrome graphical logo that leverages the Linux kernel's boot-up logo support. The ASCII art penguin will still be used when no graphical logo is found or when the existing "LOGO" Kconfig option is disabled. (Those Tux logo assets being here.) This monochrome logo support in the DRM Panic handler was sent out as part of this week's drm-misc-next pull request ahead of the Linux 6.11 merge window in July. This week's drm-misc-next material also includes TTM memory management improvements, various fixes to the smaller Direct Rendering Manager drivers, and also the previously talked about monochrome TV support for the Raspberry Pi. Long-time Slashdot reader unixbhaskar thinks the new option "will certainly satisfy the modern people... But it is not as eye candy as people think... Moreover, it is monochrome, so certainly not resource-hungry. Plus, if all else fails, the ASCII art logo is still there to show!"

What if across the bottom of the Atlantic Ocean, six high-voltage power cables stretched — each over 2,000 miles long. CNN reports that a group of entrepreneurs "wants to build what would be the world's largest subsea energy interconnector between continents, linking Europe and North America...to connect places like the United Kingdom's west with eastern Canada, and potentially New York with western France... "The Europe-US cables could send 6 gigawatts of energy in both directions at the speed of light, said Laurent Segalen, founder of the London-based Megawatt-X renewable energy firm, who is also part of the trio proposing the transatlantic interconnector. That's equivalent to what six large-scale nuclear power plants can generate, transmitted in near-real time." The interconnector would send renewable energy both east and west, taking advantage of the sun's diurnal journey across the sky. "When the sun is at its zenith, we probably have more power in Europe than we can really use," said Simon Ludlam, founder and CEO of Etchea Energy, and one of the trio of Europeans leading the project. "We've got wind and we've also got too much solar. That's a good time to send it to a demand center, like the East Coast of the United States. Five, six hours later, it's the zenith in the East Coast, and obviously, we in Europe have come back for dinner, and we get the reverse flow," he added. The transatlantic interconnector is still a proposal, but networks of green energy cables are starting to sprawl across the world's sea beds. They are fast becoming part of a global climate solution, transmitting large amounts of renewable energy to countries struggling to make the green transition alone. But they are also forging new relations that are reshaping the geopolitical map and shifting some of the world's energy wars down to the depths of the ocean... Already, energy cables run between several countries in Europe, most of them allied neighbors. Not all of them carry renewable power exclusively — that's sometimes determined by what makes up each country's energy grid — âbut new ones are typically being built for a green energy future. The UK, where land space for power plants is limited, is already connected with Belgium, Norway, the Netherlands and Denmark under the sea. It has signed up to a solar and wind link with Morocco to take advantage of the North African country's many hours of sunlight and strong trade winds that run across the equator. Similar proposals are popping up around the globe. A project called Sun Cable seeks to send solar power from sunny Australia, where land is abundant, to the Southeast Asian nation of Singapore, which also has plenty of sun but very little room for solar farms. India and Saudi Arabia plan to link their respective power grids via the Arabian Sea, part of a broader economic corridor plan to connect Asia, the Middle East and Europe.

It transforms water into the fuel — one of the first fuel plants in the world to do so. The Washington Post visits a facility in Corpus Christi, Texas using renewable energy to produce "green" hydrogen. The plant feeds water through machines that pull out its hydrogen atoms... [T]he hydrogen is chemically transformed into diesel for delivery trucks. This process could represent the biggest change in how fuel for planes, ships, trains and trucks is made since the first internal combustion engine fired up in the 19th century... Turning hydrogen into liquid fuel could help slash planet-warming pollution from heavy vehicles, cutting a key source of emissions that contribute to climate change. But to fulfill that promise, companies will have to build massive numbers of wind turbines and solar panels to power the energy-hungry process. Regulators will have to make sure hydrogen production doesn't siphon green energy that could go towards cleaning up other sources of global warming gases, such as homes or factories. Although cars and light trucks are shifting to electric motors, other forms of transport will likely rely on some kind of liquid fuel for the foreseeable future. Batteries are too heavy for planes and too bulky for ships. Extended charging times could be an obstacle for long-haul trucks, and some rail lines may be too expensive to electrify. Together, these vehicles represent roughly half of emissions from transportation, the fourth-biggest source of greenhouse gases. To wean machines off oil, companies like Infinium, the owner of this plant, are starting to churn out hydrogen-based fuels that — in the best case — produce close to net zero emissions. They could also pave the way for a new technology, hydrogen fuel cells, to power planes, ships and trucks in the second half of this century. For now, these fuels are expensive and almost no one makes them, so the U.S. government, businesses and philanthropists including Bill Gates are investing billions of dollars to build up a hydrogen industry that could cut eventually some of the most stubborn, hard-to-remove carbon pollution. Most scenarios for how the world could avoid the worst effects of climate change envision hydrogen cleaning up emissions in transportation, as well as in fertilizer production and steel and chemical refining. But if they're not made with dedicated renewable energy, hydrogen-based fuels could generate even more pollution than regular diesel, creating a wasteful boondoggle that sets the world back in the fight against climate change. Their potential comes down to the way plants like this produce them... Only about 40 percent of the power on the [Texas] electric grid is from renewables, with the rest coming from natural gas and coal, according to state data. That grid energy is what flows through the power line into the Infinium plant. "One day, heavy transportation may shift to fuel cells that run on pure hydrogen and emit only water vapor from their tailpipes," the article points out. But to accommodate today's carbon-burning vehicles, Infinium produces "chemical copies of existing fuels made with crude oil" by combining captured carbon with green hydrogen. "A truck running on diesel made from hydrogen using only renewable electricity would create 89 percent fewer greenhouse gas emissions over the course of its lifetime than a truck burning diesel made from petroleum, according to a 2022 analysis from the European nonprofit Transport & Environment."
