Satellite-to-phones service provider AST SpaceMobile announced a deal with Verizon to provide remote coverage across the United States. "Verizon's deal effectively includes a $100 million raise for AST, as well, in the form of $65 million in commercial service prepayments and $35 million in debt via convertible notes," reports CNBC. "The companies said that $45 million of the prepayments 'are subject to certain conditions' such as needed regulatory approvals and signing of a definitive commercial agreement." Shares of AST jumped 69% in trading to close at $9.02 a share -- the largest single day rise for the company's stock since it went public in 2021. From the report: AST SpaceMobile is building satellites to provide broadband service to unmodified smartphones, in the nascent "direct-to-device" communications market. [...] The Verizon partnership follows a similar pattern to AT&T's work with AST. Back in January, AT&T was a co-debt investor in the company alongside Google and Vodafone. The companies then established the commercial agreement earlier this month, which "lays out in much more detail how we will ultimately offer service together," AST's Chief Strategy Officer Scott Wisniewski said in a statement to CNBC. [...] AST expects to launch its first five commercial satellites later this year.

An anonymous reader quotes a report from the BBC: A sophisticated joint European-Japanese satellite has launched to measure how clouds influence the climate. Some low-level clouds are known to cool the planet, others at high altitude will act as a blanket. The Earthcare mission will use a laser and a radar to probe the atmosphere to see precisely where the balance lies. It's one of the great uncertainties in the computer models used to forecast how the climate will respond to increasing levels of greenhouse gases. "Many of our models suggest cloud cover will go down in the future and that means that clouds will reflect less sunlight back to space, more will be absorbed at the surface and that will act as an amplifier to the warming we would get from carbon dioxide," Dr Robin Hogan, from the European Centre for Medium-Range Weather Forecasts, told BBC News.

The 2.3-tonne satellite was sent up from California on a SpaceX rocket. The project is led by the European Space Agency (ESA), which has described it as the organization's most complex Earth observation venture to date. Certainly, the technical challenge in getting the instruments to work as intended has been immense. It's taken fully 20 years to go from mission approval to launch. Earthcare will circle the Earth at a height of about 400km (250 miles). It's actually got four instruments in total that will work in unison to get at the information sought by climate scientists.

The simplest is an imager -- a camera that will take pictures of the scene passing below the spacecraft to give context to the measurements made by the other three instruments. Earthcare's European ultraviolet laser will see the thin, high clouds and the tops of clouds lower down. It will also detect the small particles and droplets (aerosols) in the atmosphere that influence the formation and behavior of clouds. The Japanese radar will look into the clouds, to determine how much water they are carrying and how that's precipitating as rain, hail and snow. And a radiometer will sense how much of the energy falling on to Earth from the Sun is being reflected or radiated back into space.

Danny Goodwin reports via Search Engine Land: A trove of leaked Google documents has given us an unprecedented look inside Google Search and revealed some of the most important elements Google uses to rank content. Thousands of documents, which appear to come from Google's internal Content API Warehouse, were released March 13 on Github by an automated bot called yoshi-code-bot. These documents were shared with Rand Fishkin, SparkToro co-founder, earlier this month.

What's inside. Here's what we know about the internal documents, thanks to Fishkin and [Michael King, iPullRank CEO]:

Current: The documentation indicates this information is accurate as of March.
Ranking features: 2,596 modules are represented in the API documentation with 14,014 attributes.
Weighting: The documents did not specify how any of the ranking features are weighted -- just that they exist.
Twiddlers: These are re-ranking functions that "can adjust the information retrieval score of a document or change the ranking of a document," according to King.
Demotions: Content can be demoted for a variety of reasons, such as: a link doesn't match the target site; SERP signals indicate user dissatisfaction; Product reviews; Location; Exact match domains; and/or Porn.
Change history: Google apparently keeps a copy of every version of every page it has ever indexed. Meaning, Google can "remember" every change ever made to a page. However, Google only uses the last 20 changes of a URL when analyzing links.

Other interesting findings. According to Google's internal documents:

Freshness matters -- Google looks at dates in the byline (bylineDate), URL (syntacticDate) and on-page content (semanticDate).
To determine whether a document is or isn't a core topic of the website, Google vectorizes pages and sites, then compares the page embeddings (siteRadius) to the site embeddings (siteFocusScore).
Google stores domain registration information (RegistrationInfo).
Page titles still matter. Google has a feature called titlematchScore that is believed to measure how well a page title matches a query.
Google measures the average weighted font size of terms in documents (avgTermWeight) and anchor text. What does it all mean? According to King: "[Y]ou need to drive more successful clicks using a broader set of queries and earn more link diversity if you want to continue to rank. Conceptually, it makes sense because a very strong piece of content will do that. A focus on driving more qualified traffic to a better user experience will send signals to Google that your page deserves to rank." [...] Fishkin added: "If there was one universal piece of advice I had for marketers seeking to broadly improve their organic search rankings and traffic, it would be: 'Build a notable, popular, well-recognized brand in your space, outside of Google search.'"

The WeWork founder Adam Neumann has shelved his bid to acquire the bankrupt shared office space provider. From a report: It emerged earlier this year that Neumann, who was ousted from the business in 2019 following a botched attempt to take it public on the stock market, was seeking to buy the business. His new real estate venture, Flow Global, submitted a bid of more than $500m to take over WeWork and its assets. On Tuesday morning, however, Neumann confirmed that Flow was walking away from his dream to take back control of the firm.

"For several months, we tried to work constructively with WeWork to create a strategy that would allow it to thrive," he told DealBook. "Instead, the company looks to be emerging from bankruptcy with a plan that appears unrealistic and unlikely to succeed." WeWork, with over $13bn in long-term leases, filed for Chapter 11 bankruptcy protection last November in order to renegotiate these agreements. At its peak, the company had been valued at $47bn as investors including the Japanese multinational SoftBank lined up to back it. As it prepared to go public in 2019, however, analysts gave it a far lower valuation. After it eventually went public, in 2021, its market valuation tumbled to less than $50m.

T-Mobile said Tuesday that it plans to acquire most of U.S. Cellular, including stores, some of the wireless operator's spectrum and its customers, in a deal worth $4.4 billion. The deal includes cash and up to $2 billion of debt. From a report: T-Mobile said it will use U.S. Cellular wireless spectrum to improve coverage in rural areas while offering better connectivity to U.S. Cellular customers around the United States. The company said it will allow U.S. Cellular customers to keep their current plans or switch to a T-Mobile plan. U.S. Cellular will retain some of its wireless spectrum and towers and will lease space on at least 2,100 additional towers to T-Mobile. The companies expect the deal to close in mid-2025.

Witnessing the blood-red fires of a volcanic eruption on Earth is memorable. But to see molten rock bleed out of a volcano on a different planet would be extraordinary. That is close to what scientists have spotted on Venus: two vast, sinuous lava flows oozing from two different corners of Earth's planetary neighbor. From a report: "After you see something like this, the first reaction is 'wow,'" said Davide Sulcanese, a doctoral student at the Universita d'Annunzio in Pescara, Italy, and an author of a study reporting the discovery in the journal Nature Astronomy, published on Monday. Earth and Venus were forged at the same time. Both are made of the same primeval matter, and both are the same age and size. So why is Earth a paradise overflowing with water and life, while Venus is a scorched hellscape with acidic skies?

Volcanic eruptions tinker with planetary atmospheres. One theory holds that, eons ago, several apocalyptic eruptions set off a runaway greenhouse effect on Venus, turning it from a temperate, waterlogged world into an arid desert of burned glass. To better understand its volcanism, scientists hoped to catch a Venusian eruption in the act. But although the planet is known to be smothered in volcanoes, an opaque atmosphere has prevented anyone from seeing an eruption the way spacecraft have spotted them on Io, the hypervolcanic moon of Jupiter. In the 1990s, NASA's spacecraft Magellan used cloud-penetrating radar to survey most of the planet. But back then, the relatively low-resolution images made spotting fresh molten rock a troublesome task.

A North Korean rocket carrying its second spy satellite exploded midair on Monday, state media reported, after its neighbors strongly rebuked its planned launch. From a report: The North's official Korean Central News Agency said it launched a spy satellite aboard a new rocket at its main northwestern space center. But KCNA said the rocket blew up during a first-stage flight soon after liftoff due to a suspected engine problem. Earlier Monday, North Korea had notified Japan's coast guard about its plans to launch "a satellite rocket," with a warning to exercise caution in the waters between the Korean Peninsula and China and east of the main Philippine island of Luzon during a launch window from Monday through June 3.

South Korea's Joint Chiefs of Staff later said it detected a launch trajectory believed to be of a spy satellite fired from the North's main space center at 10:44 p.m. on Monday. Four minutes later, many fragments were spotted in the waters, it said. Japanese Prime Minister's Office earlier issued a missile alert for the island of Okinawa following North Korea's launch. The alert was lifted soon after. Japan's NHK public television earlier reported that an image captured by a camera in northeastern China showed an orange light in the sky and then an apparent explosion a moment later.

Space.com calls it a movie "adding more combustible material to the inferno of AI unease sweeping the globe." Its director tells them James Cameron was a huge inspiration, saying Atlas "has an Aliens-like vibe because of the grounded, grittiness to it." (You can watch the movie's trailer here...)

But Tom's Guide says "the reviews are just as shocking as the movie's AI." Its "audience score" on Rotten Tomatoes is 55% — but its aggregate score from professional film critics is 16%. The Hollywood Reporter called it "another Netflix movie to half-watch while doing laundry." ("The star plays a data analyst forced to team up with an AI robot in order to prevent an apocalypse orchestrated by a different AI robot...") The site Giant Freakin Robot says "there seems to be a direct correlation between how much money the streaming platform spends on green screen effects and how bad the movie is" (noting the film's rumored budget of $100 million)...

But Tom's Guide defends it as a big-budget sci-fi thriller that "has an interesting premise that makes you think about the potential dangers of AI progression." Our world has always been interested in computers and machines, and the very idea of technology turning against us is unsettling. That's why "Atlas" works as a movie, but professional critics have other things to say. Ross McIndoe from Slant Magazine said: "Atlas seems like a story that should have been experienced with a gamepad in hand...." Todd Gilchrist from Variety didn't enjoy the conventional structure that "Atlas" followed...

However, even though the score is low and the reviews are pretty negative, I don't want to completely bash this movie... If I'm being completely honest, most movies and TV shows nowadays are taken too seriously. The more general blockbusters are supposed to be entertaining and fun, with visually pleasing effects that keep you hooked on the action. This is much like "Atlas", which is a fun watch with an unsettling undertone focused on the dangers of evolving AI...

Being part of the audience, we're supposed to just take it in and enjoy the movie as a casual viewer. This is why I think you should give "Atlas" a chance, especially if you're big into dramatic action sequences and have enjoyed movies like "Terminator" and "Pacific Rim".

In 2011 Ross Ulbricht launched an anonymous, Tor-hidden "darknet" marketplace (with transactions conducted in bitcoin). By 2015 he'd been sentenced to life in prison for crimes including money laundering, distributing narcotics, and trafficking in fraudulent identity documents — without the possibility of parole.

Today a U.S. presidential candidate promised to commute that life sentence — Donald Trump, speaking at the national convention of the Libertarian Party as it prepares to nominate its own candidate for president.

Commuting Ulbricht's life sentence is "a top demand" of a political movement that intends to run its own candidate against Trump, reports Semafor: "On day one, we will commute the sentence," Trump said, offering to free the creator of what was once the internet's most infamous drug clearinghouse. "We will bring him home." His speeches more typically include a pledge to execute drug dealers, citing China as a model.

"It's time to be winners," said Trump, asking rhetorically if third party delegates wanted to go on getting single-digit protest votes. "I'm asking for the Libertarian Party's endorsement, or at least lots of your votes...."

"I've been indicted by the government on 91 different things," Trump said. "So if I wasn't a libertarian before, I sure as hell am a libertarian now."
More coverage from NBC News: At times, Trump turned on the crowd, criticizing libertarians' turnout at previous elections. "You can keep going the way you have for the last long decades and get your 3% and meet again, get another 3%," Trump said following jeers from the crowd.
Another high-profile supporter for commuting Ulbricht's sentence is actor-turned documentary maker Alex Winter. Best known for playing slacker Bill S. Preston Esq in Bill & Ted's Excellent Adventure and its sequels, Winter also directed, wrote, and co-produced the 2015 documentary Deep Web: The Untold Story of Bitcoin and the Silk Road (narrated by Keanu Reeves).

Writing earlier this month in Rolling Stone, Winter called Silk Road "inarguably a criminal operation" but also "a vibrant and diverse community of people from around the world. They were not only there for drugs but for the freedom of an encrypted and anonymous space, to convene and discuss everything from politics to literature and art, philosophy and drugs, drug recovery, and the onerous War on Drugs..." It's my firm opinion, and the opinion of many prison-system and criminal-law experts, that [Ulbricht's] sentence is disproportionate to his charges and that he deserves clemency. This case indeed reflects just one of the millions of unjust sentences in the long and failed War on Drugs... No matter what one thinks of Ulbricht, Silk Road, or the crimes that may have been committed, 10 years in prison is more than sufficient and customary punishment for those offenses or sins. Ross Ulbricht should be free.

An anonymous reader quotes a report from Ars Technica: A team of physicists has discovered that it's possible to build a real, actual, physical warp drive and not break any known rules of physics. One caveat: the vessel doing the warping can't exceed the speed of light, so you're not going to get anywhere interesting any time soon. But this research still represents an important advance in our understanding of gravity. [...] In a paper accepted for publication in the journal Classical and Quantum Gravity, [an international team of physicists led by Jared Fuchs at the University of Alabama in Huntsville] dug deep into relativity to explore if any version of a warp drive could work. The equations of general relativity are notoriously difficult to solve, especially in complex cases such as a warp drive. So the team turned to software algorithms; instead of trying to solve the equations by hand, they explored their solutions numerically and verified that they conformed to the energy conditions.

The team did not actually attempt to construct a propulsion device. Instead, they explored various solutions to general relativity that would allow travel from point to point without a vessel undergoing any acceleration or experiencing any overwhelming gravitational tidal forces within the vessel, much to the comfort of any imagined passengers. They then checked whether these solutions adhered to the energy conditions that prevent the use of exotic matter. The researchers did indeed discover a warp drive solution: a method of manipulating space so that travelers can move without accelerating. There is no such thing as a free lunch, however, and the physicality of this warp drive does come with a major caveat: the vessel and passengers can never travel faster than light. Also disappointing: the fact that the researchers behind the new work don't seem to bother with figuring out what configurations of matter would allow the warping to happen. The findings have been published in the journal Classical and Quantum Gravity.

China's rapid solar power expansion is slowing due to grid bottlenecks, market reforms, and diminishing rooftop space, with new solar builds dropping 32% in March year-on-year. Reuters reports: The country's solar power expansion is slowing due to tighter curbs on supplying excess power from rooftop solar into the grid and changes in electricity pricing that are denting the economics of new solar projects. Forecasts show China's solar build this year will be heavily outpaced by growth in its photovoltaic (PV) module manufacturing capacity, raising the prospect the country will export more solar panels despite a trade backlash in Europe and the U.S. The main factor slowing the expansion of distributed solar - installations built near the point of use, mostly on rooftops - is that there is not enough storage or transmission capacity to soak up the excess power generated when the sun is shining. That in turn is leading regulators to take away some of the price support that led to the rapid growth of distributed solar. "In the next couple of years, this is going to be a huge problem that all provinces will face as grids are oversaturated, the infrastructure is overwhelmed," said Cosimo Ries, an analyst with Trivium China, a policy research group. [...]

Renewable generators previously enjoyed a guarantee that grid operators would buy nearly all of their power at a rate tied to the coal index. That guarantee was lifted on April 1 and took effect earlier in some places, three industry experts said. Now, renewable generation is increasingly subject to less favourable market pricing. Shenhua Energy, a state-run coal and power firm, said in its first-quarter report that prices for its solar power fell 34.2% year-on-year to 283 yuan per megawatt-hour (MWh), while its coal power prices fell just 2.4% to 406 yuan per MWh. Wang Xiuqiang, a researcher at consultancy Beijing Linghang, attributed the lower solar prices and profitability to a higher proportion of market-based pricing. At the same time, grid companies are dialling back the 5% curtailment limit, "creating the risk for project owners that their generation might not be bought", said David Fishman of Shanghai-based energy consultancy the Lantau Group.

Curtailment for Huaneng Power International, a major state-owned generator, rose to 7.7% in the first quarter from 3.1% a year earlier, Jefferies analysts said in a client note, citing Huaneng management. In a further challenge, the easiest-to-site projects have already been largely developed, said Shi Lida, research manager at Yongan Guofu Asset Management. At sites still available, rooftops may need to be reinforced, grid connections may be limited, or hours of sunlight may be short. "If your costs don't continue to fall, the investment will not be cost effective," Shi said. Further reading: Germany Has Too Many Solar Panels, and It's Pushed Energy Prices Negative

Using the Euclid space telescope, astronomers have discovered dozens of rogue planets drifting without stars in the Orion nebula. The Guardian reports: The European Space Agency (Esa) launched the $1 billion observatory last summer on a six-year mission to create a 3D map of the cosmos. Armed with its images, scientists hope to understand more about the mysterious 95% of the universe that is unexplained. The first wave of scientific results come from only 24 hours of observations, which revealed 11m objects in visible light and 5m in infrared. Along with the rogue planets, the researchers describe new star clusters, dwarf galaxies and very distant, bright galaxies from the first billion years of the universe.

A flurry of new images from the same observations are the largest ever taken in space and demonstrate the stunning wide-field views that astronomers can expect from Euclid in the coming years. Among those released on Thursday is a breathtaking image of Messier 78, a vibrant star nursery shrouded in interstellar dust, that reveals complex filaments of gas and dust in unprecedented detail. One of the newly released images shows Abell 2390, a giant conglomeration of more than 50,000 Milky Way-like galaxies. Such galaxy clusters contain up to 10 trillion times as much mass as the sun, much of which is believed to be elusive dark matter. Another image of the Abell 2764 galaxy cluster reveals hundreds of galaxies orbiting within a halo of dark matter.

Other images capture NGC 6744, one of the largest spiral galaxies in the nearby universe, and the Dorado group of galaxies, where evolving and merging galaxies produce shell-like structures and vast, curving tidal tails. The rogue planets spotted by Euclid are about 3m years old, making them youngsters on the cosmic scale. They are at least four times as big as Jupiter and were detected thanks to the warmth they emit. Astronomers know they are free-floating because they are so far away from the nearest stars. The celestial strays are destined to drift through the galaxy unless they encounter a star that pulls them into orbit.

fjo3 quotes a report from Reuters: SpaceX on Wednesday launched an inaugural batch of operational spy satellites it built as part of a new U.S. intelligence network designed to significantly upgrade the country's space-based surveillance powers, the first deployment of several more planned this year. The spy network was revealed in a pair of Reuters reports earlier this year showing SpaceX is building hundreds of satellites for the U.S. National Reconnaissance Office, an intelligence agency, for a vast system in orbit capable of rapidly spotting ground targets almost anywhere in the world.

SpaceX's Falcon 9 rocket lifted off from the Vandenberg Space Force Base in Southern California at 4 a.m. EDT on Wednesday, carrying into space what the NRO said was the "first launch of the NRO's proliferated systems featuring responsive collection and rapid data delivery." "Approximately half a dozen launches supporting NRO's proliferated architecture are planned for 2024, with additional launches expected through 2028," the agency said, without naming the number of satellites deployed.

Longtime Slashdot reader schwit1 shares a report from Ars Technica: The first crewed test flight of Boeing's long-delayed Starliner spacecraft won't take off as planned Saturday and could face a longer postponement as engineers evaluate a stubborn leak of helium from the capsule's propulsion system. NASA announced the latest delay of the Starliner test flight late Tuesday. Officials will take more time to consider their options for how to proceed with the mission after discovering the small helium leak on the spacecraft's service module.

The space agency did not describe what options are on the table, but sources said they range from flying the spacecraft "as is" with a thorough understanding of the leak and confidence it won't become more significant in flight, to removing the capsule from its Atlas V rocket and taking it back to a hangar for repairs. Theoretically, the former option could permit a launch attempt as soon as next week. The latter alternative could delay the launch until at least late summer.

"The team has been in meetings for two consecutive days, assessing flight rationale, system performance, and redundancy," NASA said in a statement Tuesday night. "There is still forward work in these areas, and the next possible launch opportunity is still being discussed. NASA will share more details once we have a clearer path forward."

The United States has assessed that Russia launched what is likely a counter space weapon last week that's now in the same orbit as a U.S. government satellite, Pentagon spokesman Maj. Gen. Pat Ryder confirmed Tuesday. From a report: "What I'm tracking here is on May 16, as you highlighted, Russia launched a satellite into low Earth orbit that we that we assess is likely a counter space weapon presumably capable of attacking other satellites in low Earth orbit," Ryder said when questioned by ABC News about the information, which was made public earlier Tuesday by Robert Wood, deputy U.S. ambassador to the United Nations.

"Russia deployed this new counter space weapon into the same orbit as a U.S. government satellite," Ryder continued. "And so assessments further indicate characteristics resembling previously deployed counter space payloads from 2019 and 2022." Ryder added: "Obviously, that's something that we'll continue to monitor. Certainly, we would say that we have a responsibility to be ready to protect and defend the space domain and ensure continuous and uninterrupted support to the joint and combined force. And we'll continue to balance the need to protect our interests in space with our desire to preserve a stable and sustainable space environment." When asked if the Russian counter space weapon posed a threat to the U.S. satellite, Ryder responded: "Well, it's a counter space weapon in the same orbit as a U.S. government satellite."

After being rumored for years, Sonos has officially entered the headphones market with its new Ace headphones. "The Sonos Ace wireless over-ear active noise-canceling headphones are specified to go toe-to-toe with the established market leaders from the likes of Apple and Bose, and they're priced to match at $449," reports Wired. From the report: Visually, you get an elegant and notably slim pair of over-ear headphones in either a black or "soft" white matte finish. Thanks to a light 312-gram weight, and with some very well-judged clamping force and a clever hanger arrangement that conceals the hinged yoke inside the body of the ear cups, it means all-day comfort. The combination of memory foam, vegan leather, and stainless steel is equally beneficial where comfort and aesthetics are concerned. Branding is restricted to one ear cup, and it's laser-etched, so it manages to be understated while still catching the eye. Where the Apple AirPods Max shout "look at ME!," the Sonos Ace enunciate it quietly and precisely.

As far as performance is concerned, you get all the bells and whistles you'd expect. Wireless connectivity is via Bluetooth 5.4, and they have SBC and AAC codecs, allowing the Ace to be compatible with ALAC and Qualcomm Snapdragon Sound aptX Lossless. Sound is delivered by a pair of custom-designed 40-mm dynamic drivers. Sonos is characteristically coy about frequency response, but from my brief listen at a recent press event in London, they were full-range enough for real bass. Ported acoustic architecture allows for optimum low-frequency extension. Spatial audio is available via those streaming services that support Dolby Atmos and/or Sony 360 Reality Audio, and Sonos' Intelligent Motion Processing with Dolby Head Tracking dynamically follows your head movement to provide an even greater sensation of immersion and envelopment.

There are other cool features that most other headphones can't offer, by virtue of Sonos' ubiquity in many homes. At launch, the Ace will interact seamlessly with the Sonos Arc Dolby Atmos soundbar to swap TV sound between bar and phones at the touch of a button. Sonos suggests that compatibility with its other soundbars (Beam, Beam Gen 2, and Ray) is coming soon, along with a new TrueCinema technology that will map your listening space to reproduce your room's characteristics in the sound of the Ace. [...]

This week the nonprofit Linux Foundation announced the launch of the High Performance Software Foundation, which "aims to build, promote, and advance a portable core software stack for high performance computing" (or HPC) by "increasing adoption, lowering barriers to contribution, and supporting development efforts."

It promises initiatives focused on "continuously built, turnkey software stacks," as well as other initiatives including architecture support and performance regression testing. Its first open source technical projects are:

- Spack: the HPC package manager.

- Kokkos: a performance-portable programming model for writing modern C++ applications in a hardware-agnostic way.

- Viskores (formerly VTK-m): a toolkit of scientific visualization algorithms for accelerator architectures.

- HPCToolkit: performance measurement and analysis tools for computers ranging from desktop systems to GPU-accelerated supercomputers.

- Apptainer: Formerly known as Singularity, Apptainer is a Linux Foundation project providing a high performance, full featured HPC and computing optimized container subsystem.

- E4S: a curated, hardened distribution of scientific software packages.

As use of HPC becomes ubiquitous in scientific computing and digital engineering, and AI use cases multiply, more and more data centers deploy GPUs and other compute accelerators. The High Performance Software Foundation will provide a neutral space for pivotal projects in the high performance computing ecosystem, enabling industry, academia, and government entities to collaborate on the scientific software.

The High Performance Software Foundation benefits from strong support across the HPC landscape, including Premier Members Amazon Web Services (AWS), Hewlett Packard Enterprise, Lawrence Livermore National Laboratory, and Sandia National Laboratories; General Members AMD, Argonne National Laboratory, Intel, Kitware, Los Alamos National Laboratory, NVIDIA, and Oak Ridge National Laboratory; and Associate Members University of Maryland, University of Oregon, and Centre for Development of Advanced Computing.
In a statement, an AMD vice president said that by joining "we are using our collective hardware and software expertise to help develop a portable, open-source software stack for high-performance computing across industry, academia, and government." And an AWS executive said the high-performance computing community "has a long history of innovation being driven by open source projects. AWS is thrilled to join the High Performance Software Foundation to build on this work. In particular, AWS has been deeply involved in contributing upstream to Spack, and we're looking forward to working with the HPSF to sustain and accelerate the growth of key HPC projects so everyone can benefit."

The new foundation will "set up a technical advisory committee to manage working groups tackling a variety of HPC topics," according to the announcement, following a governance model based on the Cloud Native Computing Foundation.

"Blue Origin's tourism rocket has launched passengers to the edge of space for the first time in nearly two years," reports CNN, "ending a hiatus prompted by a failed uncrewed test flight." The New Shepard rocket and capsule lifted off at 9:36 a.m. CT (10:36 a.m. ET) from Blue Origin's facilities on a private ranch in West Texas.

NS-25, Blue Origin's seventh crewed flight to date, carried six customers aboard the capsule: venture capitalist Mason Angel; Sylvain Chiron, founder of the French craft brewery Brasserie Mont-Blanc; software engineer and entrepreneur Kenneth L. Hess; retired accountant Carol Schaller; aviator Gopi Thotakura; and Ed Dwight, a retired US Air Force captain selected by President John F. Kennedy in 1961 to be the nation's first Black astronaut candidate... Dwight completed that challenge and reached the edge of space at the age of 90, making him the oldest person to venture to such heights, according to a spokesperson from Blue Origin...

"It's a life-changing experience," he said. "Everybody needs to do this."

The rocket booster landed safely a couple minutes prior to the capsule. During the mission, the crew soared to more than three times the speed of sound, or more than 2,000 miles per hour. The rocket vaulted the capsule past the Kármán line, an area 62 miles (100 kilometers) above Earth's surface that is widely recognized as the altitude at which outer space begins...
"And at the peak of the flight, passengers experienced a few minutes of weightlessness and striking views of Earth through the cabin windows."

"China's navy has apparently tested out a hypersonic rail gun," reports Futurism, describing it as "basically a device that uses a series of electromagnets to accelerate a projectile to incredible speeds."

But "during a demonstration of its power, things didn't go quite as planned." As the South China Morning Post reports, the rail gun test lobbed a precision-guided projectile — or smart bomb — nine miles into the stratosphere. But because it apparently didn't go up as high as it was supposed to, the test was ultimately declared unsuccessful. This conclusion came after an analysis led by Naval Engineering University professor Lu Junyong, whose team found with the help of AI that even though the winged smart bomb exceeded Mach 5 speeds, it didn't perform as well as it could have. This occurred, as Lu's team found, because the projectile was spinning too fast during its ascent, resulting in an "undesirable tilt."
But what's more interesting is the project itself. "Successful or not, news of the test is a pretty big deal given that it was just a few months ago that reports emerged about China's other proposed super-powered rail gun, which is intended to send astronauts on a Boeing 737-size ship into space.... which for the record did not make it all the way to space..." Chinese officials, meanwhile, are paying lip service to the hypersonic rail gun technology's potential to revolutionize civilian travel by creating even faster railways and consumer space launches, too.
Japan and France also have railgun projects, according to a recent article from Defense One. "Yet the nation that has demonstrated the most continuing interest is China," with records of railgun work dating back as far as 2011: The Chinese team claimed that their railgun can fire a projectile 100 to 200 kilometers at Mach 6. Perhaps most importantly, it uses up to 100,000 AI-enabled sensors to identify and fix any problems before critical failure, and can slowly improve itself over time. This, they said, had enabled them to test-fire 120 rounds in a row without failure, which, if true, suggests that they solved a longstanding problem that reportedly bedeviled U.S. researchers. However, the team still has a ways to go before mounting an operational railgun on a ship; according to one Chinese article, the projectiles fired were only 25mm caliber, well below the size of even lightweight naval artillery.

As with many other Chinese defense technology programs, much remains opaque about the program...

While railguns tend to get the headlines, this lab has made advances in a wide range of electric and electromagnetic applications for the PLA Navy's warships. For example, the lab's research on electromagnetic launch technology has also been applied to the development of electromagnetic catapults for the PLAN's growing aircraft carrier fleet...

While it remains to be seen whether the Chinese navy can develop a full-scale railgun, produce it at scale, and integrate it onto its warships, it is obvious that it has made steady advances in recent years on a technology of immense military significance that the US has abandoned.

Earlier this week the Washington Post reported that America's Defense department "is growing concerned that the United Launch Alliance, one of its key partners in launching national security satellites to space, will not be able to meet its needs to counter China and build its arsenal in orbit with a new rocket that ULA has been developing for years." In a letter sent Friday to the heads of Boeing's and Lockheed Martin's space divisions, Air Force Assistant Secretary Frank Calvelli used unusually blunt terms to say he was growing "concerned" with the development of the Vulcan rocket, which the Pentagon intends to use to launch critical national security payloads but which has been delayed for years. ULA, a joint venture of Boeing and Lockheed Martin, was formed nearly 20 years ago to provide the Defense Department with "assured access" to space. "I am growing concerned with ULA's ability to scale manufacturing of its Vulcan rocket and scale its launch cadence to meet our needs," he wrote in the letter, a copy of which was obtained by The Washington Post. "Currently there is military satellite capability sitting on the ground due to Vulcan delays...."

ULA originally won 60 percent of the Pentagon's national security payloads under the current contract, known as Phase 2. SpaceX won an award for the remaining 40 percent, but it has been flying its reusable Falcon 9 rocket at a much higher rate. ULA launched only three rockets last year, as it transitions to Vulcan; SpaceX launched nearly 100, mostly to put up its Starlink internet satellite constellation. Both are now competing for the next round of Pentagon contracts, a highly competitive procurement worth billions of dollars over several years. ULA is reportedly up for sale; Blue Origin is said to be one of the suitors...

In a statement to The Post, ULA said that its "factory and launch site expansions have been completed or are on track to support our customers' needs with nearly 30 launch vehicles in flow at the rocket factory in Decatur, Alabama." Last year, ULA CEO Tory Bruno said in an interview that the deal with Amazon would allow the company to increase its flight rate to 20 to 25 a year and that to meet that cadence it was hiring "several hundred" more employees. The more often Vulcan flies, he said, the more efficient the company would become. "Vulcan is much less expensive" than the Atlas V rocket that the ULA currently flies, Bruno said, adding that ULA intends to eventually reuse the engines. "As the flight rate goes up, there's economies of scale, so it gets cheaper over time. And of course, you're introducing reusability, so it's cheaper. It's just getting more and more competitive."
The article also notes that years ago ULA "decided to eventually retire its workhorse Atlas V rocket after concerns within the Pentagon and Congress that it relied on a Russian-made engine, the RD-180. In 2014, the company entered into a partnership with Jeff Bezos' Blue Origin to provide its BE-4 engines for use on Vulcan. However, the delivery of those engines was delayed for years — one of the reasons Vulcan's first flight didn't take place until earlier this year."

The article says Cavelli's letter cited the Pentagon's need to move quickly as adversaries build capabilities in space, noting "counterspace threats" and adding that "our adversaries would seek to deny us the advantage we get from space during a potential conflict."

"The United States continues to face an unprecedented strategic competitor in China, and our space environment continues to become more contested, congested and competitive."
