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."

"Albert Einstein was right," reports CNN. "There is an area at the edge of black holes where matter can no longer stay in orbit and instead falls in, as predicted by his theory of gravity."

The proof came by combining NASA's earth-orbiting NuSTAR telescope with the NICER telescope on the International Space Station to detect X-rays: A team of astronomers has for the first time observed this area — called the "plunging region" — in a black hole about 10,000 light-years from Earth. "We've been ignoring this region, because we didn't have the data," said research scientist Andrew Mummery, lead author of the study published Thursday in the journal Monthly Notices of the Royal Astronomical Society. "But now that we do, we couldn't explain it any other way."
Mummery — also a Fellow in Oxford's physics department — told CNN, "We went out searching for this one specifically — that was always the plan. We've argued about whether we'd ever be able to find it for a really long time. People said it would be impossible, so confirming it's there is really exciting."

Mummery described the plunging region as "like the edge of a waterfall." Unlike the event horizon, which is closer to the center of the black hole and doesn't let anything escape, including light and radiation, in the "plunging region" light can still escape, but matter is doomed by the powerful gravitational pull, Mummery explained. The study's findings could help astronomers better understand the formation and evolution of black holes. "We can really learn about them by studying this region, because it's right at the edge, so it gives us the most information," Mummery said...

According to Christopher Reynolds, a professor of astronomy at the University of Maryland, College Park, finding actual evidence for the "plunging region" is an important step that will let scientists significantly refine models for how matter behaves around a black hole. "For example, it can be used to measure the rotation rate of the black hole," said Reynolds, who was not involved in the study.

America's Defense Department "is rushing to expand its capacity to wage war in space," reports the New York Times, "convinced that rapid advances by China and Russia in space-based operations pose a growing threat to U.S. troops and other military assets on the ground and U.S. satellites in orbit." [T]he Defense Department is looking to acquire a new generation of ground- and space-based tools that will allow it to defend its satellite network from attack and, if necessary, to disrupt or disable enemy spacecraft in orbit, Pentagon officials have said in a series of interviews, speeches and recent statements... [T]he move to enhance warfighting capacity in space is driven mostly by China's expanding fleet of military tools in space... [U.S. officials are] moving ahead with an effort they are calling "responsible counterspace campaigning," an intentionally ambiguous term that avoids directly confirming that the United States intends to put its own weapons in space. But it also is meant to reflect this commitment by the United States to pursue its interest in space without creating massive debris fields that would result if an explosive device or missile were used to blow up an enemy satellite. That is what happened in 2007, when China used a missile to blow up a satellite in orbit. The United States, China, India and Russia all have tested such missiles. But the United States vowed in 2022 not to do any such antisatellite tests again.

The United States has also long had ground-based systems that allow it to jam radio signals, disrupting the ability of an enemy to communicate with its satellites, and is taking steps to modernize these systems. But under its new approach, the Pentagon is moving to take on an even more ambitious task: broadly suppress enemy threats in orbit in a fashion similar to what the Navy does in the oceans and the Air Force in the skies.
The article notes a recent report drafted by a former Space Force colonel cited three ways to disable enemy satellite networks: cyberattacks, ground or space-based lasers, and high-powered microwaves. "John Shaw, a recently retired Space Force lieutenant general who helped run the Space Command, agreed that directed-energy devices based on the ground or in space would probably be a part of any future system. 'It does minimize debris; it works at the speed of light,' he said. 'Those are probably going to be the tools of choice to achieve our objective." The Pentagon is separately working to launch a new generation of military satellites that can maneuver, be refueled while in space or have robotic arms that could reach out and grab — and potentially disrupt — an enemy satellite. Another early focus is on protecting missile defense satellites. The Defense Department recently started to require that a new generation of these space-based monitoring systems have built-in tools to evade or respond to possible attack. "Resiliency feature to protect against directed energy attack mechanisms" is how one recent missile defense contract described it. Last month the Pentagon also awarded contracts to two companies — Rocket Lab and True Anomaly — to launch two spacecraft by late next year, one acting as a mock enemy and the other equipped with cameras, to pull up close and observe the threat. The intercept satellite will not have any weapons, but it has a cargo hold that could carry them.
The article notes that Space Force's chief of space operations has told Senate appropriators that about $2.4 billion of the $29.4 billion in Space Force's proposed 2025 budget was set aside for "space domain awareness." And it adds that the Pentagon "is working to coordinate its so-called counterspace efforts with major allies, including Britain, Canada and Australia, through a multinational operation called Operation Olympic Defender. France has been particularly aggressive, announcing its intent to build and launch by 2030 a satellite equipped with a high-powered laser." [W]hat is clear is that a certain threshold has now been passed: Space has effectively become part of the military fighting domain, current and former Pentagon officials said. "By no means do we want to see war extend into space," Lt. Gen. DeAnna Burt, deputy chief of space operations, said at a Mitchell Institute event this year. "But if it does, we have to be prepared to fight and win."

An anonymous reader quotes a report from The Guardian, written by Caroline Haskins: On May 7th and 8th in Washington, D.C., the city's biggest convention hall welcomed America's military-industrial complex, its top technology companies and its most outspoken justifiers of war crimes. Of course, that's not how they would describe it. It was the inaugural "AI Expo for National Competitiveness," hosted by the Special Competitive Studies Project -- better known as the "techno-economic" thinktank created by the former Google CEO and current billionaire Eric Schmidt. The conference's lead sponsor was Palantir, a software company co-founded by Peter Thiel that's best known for inspiring 2019 protests against its work with Immigration and Customs Enforcement (Ice) at the height of Trump's family separation policy. Currently, Palantir is supplying some of its AI products to the Israel Defense Forces.

The conference hall was also filled with booths representing the U.S. military and dozens of its contractors, ranging from Booz Allen Hamilton to a random company that was described to me as Uber for airplane software. At industry conferences like these, powerful people tend to be more unfiltered – they assume they're in a safe space, among friends and peers. I was curious, what would they say about the AI-powered violence in Gaza, or what they think is the future of war?

Attendees were told the conference highlight would be a series of panels in a large room toward the back of the hall. In reality, that room hosted just one of note. Featuring Schmidt and the Palantir CEO, Alex Karp, the fire-breathing panel would set the tone for the rest of the conference. More specifically, it divided attendees into two groups: those who see war as a matter of money and strategy, and those who see it as a matter of death. The vast majority of people there fell into group one. I've written about relationships between tech companies and the military before, so I shouldn't have been surprised by anything I saw or heard at this conference. But when it ended, and I departed DC for home, it felt like my life force had been completely sucked out of my body. Some of the noteworthy quotes from the panel and convention, as highlighted in Haskins' reporting, include:

"It's always great when the CIA helps you out," Schmidt joked when CIA deputy director David Cohen lent him his microphone when his didn't work.

The U.S. has to "scare our adversaries to death" in war, said Karp. On university graduates protesting Israel's war in Gaza, Karp described their views as a "pagan religion infecting our universities" and "an infection inside of our society."

"The peace activists are war activists," Karp insisted. "We are the peace activists."

A huge aspect of war in a democracy, Karp went on to argue, is leaders successfully selling that war domestically. "If we lose the intellectual debate, you will not be able to deploy any armies in the west ever," Karp said.

A man in nuclear weapons research jokingly referred to himself as "the new Oppenheimer."

Visa is rolling out new technology that will allow the payments giant to share more information about customers' preferences [non-paywalled source] based on their shopping history with retailers as it seeks to remain a top player in the competitive e-commerce space. From a report: The data will be shared via the payments giant's proprietary "tokens," which provide an added layer of security between a consumer's bank information and a merchant. Shopping inclinations and other information based on past transactions -- such as preferred categories, like movies or golf -- will be shared via token with retailers with the consent of consumers.

"It's almost entirely blind to almost all consumers," Visa Chief Executive Officer Ryan McInerney said in an interview of the company's token technology. "They just know their payments work better." The sharing of shopping data via token is one of a handful of innovations Visa unveiled at a conference in San Francisco, where it's based. Visa, one of the largest e-commerce technology companies in the world, is finding itself increasingly fending off competitors seeking larger slices of the fees merchants must pay to carry out consumer transactions.

Michael Kan reports via PCMag: AT&T has struck a deal to bring satellite internet connectivity to phones through AST SpaceMobile, a potential rival to SpaceX's Starlink. AT&T says the commercial agreement will last until 2030. The goal is "to provide a space-based broadband network to everyday cell phones," a spokesperson tells PCMag, meaning customers can receive a cellular signal in remote areas where traditional cell towers are few and far between. All they'll need to do is ensure their phone has a clear view of the sky.

AT&T has been working with Texas-based AST SpaceMobile since 2018 on the technology, which involves using satellites in space as orbiting cell towers. In January, AT&T was one of several companies (including Google) to invest $110 million in AST. In addition, the carrier created a commercial starring actor Ben Stiller to showcase AST's technology. In today's announcement, AT&T notes that "previously, the companies were working together under a Memorandum of Understanding," which is usually nonbinding. Hence, the new commercial deal suggests AT&T is confident AST can deliver fast and reliable satellite internet service to consumer smartphones -- even though it hasn't launched a production satellite.

AST has only launched one prototype satellite; in tests last year, it delivered download rates at 14Mbps and powered a 5G voice call. Following a supply chain-related delay, the company is now preparing to launch its first batch of "BlueBird" production satellites later this year, possibly in Q3. In Wednesday's announcement, AT&T adds: "This summer, AST SpaceMobile plans to deliver its first commercial satellites to Cape Canaveral for launch into low Earth orbit. These initial five satellites will help enable commercial service that was previously demonstrated with several key milestones." Still, AST needs to launch 45 to 60 BlueBird satellites before it can offer continuous coverage in the U.S., although in an earnings call, the company said it'll still be able to offer "non-continuous coverage" across 5,600 cells in the country.
