Saturn Solidifies Its Title As Moon King With Discovery of 128 New Moons (www.cbc.ca) 54

Astronomers using the Canada-France-Hawaii Telescope have discovered 128 new moons around Saturn, bringing its total to 274 -- more than all the other planets combined. CBC News reports: Jupiter and Saturn have been locked in a battle for the most moons for years -- with Saturn stealing the crown from Jupiter only two years ago when the same group of researchers found 64 additional moons orbiting it. But scientists say this discovery likely settles the score once and for all. [...] He and the other scientists working on the project made the discovery using the Canada France Hawaii Telescope, a 3.6-meter optical telescope on the summit of the dormant volcano Mauna Kea on the Big Island of Hawaii.

Scientists have been capturing pictures of the moons using the telescope since 2019. The researchers aligned and layered 44 of those images on top of one another in order to enhance the appearance of the moons and determine what they were. These moons are nothing like Earth's very own, however. Sara Mazrouei, a planetary scientist and educational developer at Humber Polytechnic, says that while we tend to think of a spherical shape when we hear the word moon, anything that orbits a planet, or another body in space that is not a sun, is considered a moon. Mazrouei says many of the moons surrounding other planets in our solar system -- including the ones observed here -- are in fact only a few kilometers across in size and oddly shaped, like an asteroid.

Dead Athena Moon Lander Seen Inside Its Crater Grave From Lunar Orbit (space.com) 28

From a Space.com article: Athena, the second lunar lander from Houston company Intuitive Machines, tipped over during its touchdown on March 6, ending up on its side within a small crater near the moon's south pole. This orientation prevented the lander's solar panels from capturing enough sunlight, and Intuitive Machines declared Athena dead on March 7. (The company's first moon lander, named Odysseus, also tipped over during its historic February 2024 touchdown but was able to operate for longer on the lunar surface.)

Athena beamed home a few shots of its surroundings before giving up the ghost. And we now have views of the lander and its crater grave from on high, courtesy of NASA's sharp-eyed Lunar Reconnaissance Orbiter (LRO). On March 7, LRO captured a gorgeous oblique photo of Athena and its landing site -- the Mons Mouton region, about 100 miles (160 kilometers) from the lunar south pole. Then, three days later, the probe snapped another pic, which provided a closer look at Athena on the shadowed floor of a 65-foot-wide (20 meters) crater.

SpaceX Launches NASA's Crew-10 Mission To ISS (apnews.com) 16

A SpaceX Falcon 9 rocket launched a four-member crew to the International Space Station on Friday night, paving the way for NASA astronauts Butch Wilmore and Suni Williams to return to Earth after being there for nine months due to issues with Boeing's Starliner capsule. Arrival is set for late Saturday night. The Associated Press reports: NASA wants overlap between the two crews so Wilmore and Williams can fill in the newcomers on happenings aboard the orbiting lab. That would put them on course for an undocking next week and a splashdown off the Florida coast, weather permitting. The duo will be escorted back by astronauts who flew up on a rescue mission on SpaceX last September alongside two empty seats reserved for Wilmore and Williams on the return leg.

Reaching orbit from NASA's Kennedy Space Center, the newest crew includes NASA's Anne McClain and Nichole Ayers, both military pilots; and Japan's Takuya Onishi and Russia's Kirill Peskov, both former airline pilots. They will spend the next six months at the space station, considered the normal stint, after springing Wilmore and Williams free. "Spaceflight is tough, but humans are tougher," McClain said minutes into the flight.
You can watch a recording of the launch here.

Wilmore and Williams aren't stranded on the International Space Station, and they weren't abandoned, the astronauts reminded CNN in a rare space-to-earth interview last month. "That's been the rhetoric. That's been the narrative from day one: stranded, abandoned, stuck -- and I get it. We both get it," [NASA astronaut Butch] Wilmore said. "But that is, again, not what our human spaceflight program is about. We don't feel abandoned, we don't feel stuck, we don't feel stranded." Wilmore added a request: "If you'll help us change the rhetoric, help us change the narrative. Let's change it to 'prepared and committed.' That's what we prefer..."

Mars' Middle Atmosphere Appears Driven By Gravity Waves 16

A new study published in the Journal of Geophysical Research Planets reveals that atmospheric gravity waves play a crucial role in driving latitudinal air currents on Mars, particularly at high altitudes. Phys.Org reports: The study applied methods developed to explore Earth's atmosphere to quantitatively estimate the influence of gravity waves on Mars' planetary circulation. [...] "On Earth, large-scale atmospheric waves caused by the planet's rotation, known as Rossby waves, are the primary influence on the way air circulates in the stratosphere, or the lower part of the middle atmosphere. But our study shows that on Mars, gravity waves (GWs) have a dominant effect at the mid and high latitudes of the middle atmosphere," said Professor Kaoru Sato from the Department of Earth and Planetary Science. "Rossby waves are large-scale atmospheric waves, or resolved waves, whereas GWs are unresolved waves, meaning they are too fine to be directly measured or modeled and must be estimated by more indirect means."

Not to be confused with gravitational waves from massive stellar bodies, GWs are an atmospheric phenomenon when a packet of air rises and falls due to variations in buoyancy. That oscillating motion is what gives rise to GWs. Due to the small-scale nature of them and the limitations of observational data, researchers have previously found it challenging to quantify their significance in the Martian atmosphere. So Sato and her team turned to the Ensemble Mars Atmosphere Reanalysis System (EMARS) dataset, produced by a range of space-based observations over many years, to analyze seasonal variations up there.

"We found something interesting, that GWs facilitate the rapid vertical transfer of angular momentum, significantly influencing the meridional, or north-south, in the middle atmosphere circulations on Mars," said graduate student Anzu Asumi. "It's interesting because it more closely resembles the behavior seen in Earth's mesosphere rather than in our stratosphere. This suggests existing Martian atmospheric circulation models may need to be refined to better incorporate these wave effects, potentially improving future climate and weather simulations."

Anonymous Sources: Starship Needs a Major Rebuild After Two Consecutive Failures (behindtheblack.com) 246

Longtime Slashdot reader schwit1 shares a report from Behind The Black: According to information at this tweet from anonymous sources, parts of Starship will likely require a major redesign due to the spacecraft's break-up shortly after stage separation on its last two test flights. These are the key take-aways, most of which focus on the redesign of the first version of Starship (V1) to create the V2 that flew unsuccessfully on those flights:

- Hot separation also aggravates the situation in the compartment.
- Not related to the flames from the Super Heavy during the booster turn.
- This is a fundamental miscalculation in the design of the Starship V2 and the engine section.
- The fuel lines, wiring for the engines and the power unit will be urgently redone.
- The fate of S35 and S36 is still unclear. Either revision or scrap.
- For the next ships, some processes may be paused in production until a decision on the design is made.
- The team was rushed with fixes for S34, hence the nervous start. There was no need to rush.
- The fixes will take much longer than 4-6 weeks.
- Comprehensive ground testing with long-term fire tests is needed. [emphasis mine]

It must be emphasized that this information comes from leaks from anonymous sources, and could be significantly incorrect. It does however fit the circumstances, and suggests that the next test flight will not occur in April but will be delayed for an unknown period beyond.

Former Google CEO Eric Schmidt Is the New Leader of Relativity Space (arstechnica.com) 16

Former Google CEO Eric Schmidt has taken control of rocket startup Relativity Space, replacing co-founder Tim Ellis as CEO and significantly funding the company's development of its medium-lift rocket, Terran R. The New York Times first reported (paywalled) the news. Ars Technica reports: Schmidt's involvement with Relativity has been quietly discussed among space industry insiders for a few months. Multiple sources told Ars that he has largely been bankrolling the company since the end of October, when the company's previous fundraising dried up. It is not immediately clear why Schmidt is taking a hands-on approach at Relativity. However, it is one of the few US-based companies with a credible path toward developing a medium-lift rocket that could potentially challenge the dominance of SpaceX and its Falcon 9 rocket. If the Terran R booster becomes commercially successful, it could play a big role in launching megaconstellations.

Schmidt's ascension also means that Tim Ellis, the company's co-founder, chief executive, and almost sole public persona for nearly a decade, is now out of a leadership position. "Today marks a powerful new chapter as Eric Schmidt becomes Relativity's CEO, while also providing substantial financial backing," Ellis wrote on the social media site X. "I know there's no one more tenacious or passionate to propel this dream forward. We have been working together to ensure a smooth transition, and I'll proudly continue to support the team as Co-founder and Board member."
Relativity also on Monday released a video outlining the development of the Terran R rocket and the work required to reach the launch pad.

According to the video, the first "flight" version of the Terran R rocket will be built this year, with tentative plans to launch from a pad at Cape Canaveral, Florida, in 2026. "The company aims to soft land the first stage of the first launch in the Atlantic Ocean," adds Ars. "However, the 'Block 1' version of the rocket will not fly again."

"Full reuse of the first stage will be delayed to future upgrades. Eventually, the Relativity officials said, they intend to reach a flight rate of 50 to 100 rockets a year with the Terran R when the vehicle is fully developed."

NASA Eliminates Chief Scientist and Other Jobs At Its Headquarters (nytimes.com) 223

NASA is eliminating approximately 20 positions, including its chief scientist and roles related to technology, policy, and diversity. The move, as part of a Trump administration effort to reduce staffing, "could be a harbinger of deeper cuts to NASA's science missions and a greater emphasis on human spaceflight, especially to Mars," reports the New York Times. From the report: The cuts affect about 20 employees at NASA, including Katherine Calvin, the chief scientist and a climate science expert. The last day of work for Dr. Calvin and the other staff members will be April 10. [...] The eliminated positions include the chief technologist and chief economist for the agency, which were part of the technology, policy and strategy office. Chief technologist positions at NASA centers like the Johnson Space Center in Houston and the Kennedy Space Center in Florida are not affected, the notice said. The agency is also cutting several positions related to diversity, equity and inclusion in its Office of Equal Opportunity. The notice said that NASA estimated severance costs would be about $1.2 million.

"To optimize our work force, and in compliance with an executive order, NASA is beginning its phased approach to a reduction in force, known as a RIF," Cheryl Wheeler, a NASA spokeswoman, said in an email. "A small number of individuals received notification Monday they are a part of NASA's RIF." Eligible employees could opt for early retirement, Ms. Wheeler said. The Democratic House staff members said they worried deeper cuts at NASA would follow.

That Galaxy Next Door? It's Home to a Monster Black Hole (npr.org) 27

NPR reports on "a monster black hole that's been lurking unseen in the galaxy next door." This appears to be the closest supermassive black hole outside our Milky Way galaxy, according to a report that's appearing in The Astrophysical Journal... "Now that there is strong evidence that it should be there, you can rest assured that we are very excitedly following up," says Jesse Han of the Center for Astrophysics, Harvard & Smithsonian, who led the study...

Han and his colleagues realized that this black hole must exist when they were studying so-called hypervelocity stars... [T]hey started out as normal stars that were part of a binary system, or two stars orbiting each other. When that kind of pair ventures too close to a supermassive black hole, says Han, "what can happen is one of the stars can get captured by the black hole. It is basically ripped apart from its companion." The bereft companion star, meanwhile, gets flung away, going at ridiculously high speeds. It's as if the black hole basically hurled it out of the galaxy.

And that explains some of what's happening in our own galaxy, writes Space.com: Tracing the trajectory of these super-speed stars using the European Space Agency's star-tracking Gaia satellite, the researchers discovered that around half of them were accelerated by the Milky Way's own supermassive black hole, Sagittarius A*. The other half, the team believes, likely fled to the outskirts of the Milky Way after a gravitational encounter with a supermassive black hole at the heart of the LMC separated these stars from their stellar binary partners.

"It is astounding to realize that we have another supermassive black hole just down the block, cosmically speaking," team leader Jesse Han of the Center for Astrophysics | Harvard & Smithsonian (CfA) said in a statement. "Black holes are so stealthy that this one has been practically under our noses this whole time."

"Their calculations suggest that the Large Magellanic Cloud must be harboring a black hole that's about 600,000 times the mass of our Sun," adds NPR. "That's smaller than the black hole at the center of the Milky Way, which is about 4 million times more massive than the Sun." Astronomers had previously thought the Large Magellanic Cloud should have a big black hole, but until now there's been no evidence of it, says Han... Now, though, astronomers have a better sense of where to hunt for any X-ray, radio, or visible-light signatures that are the telltale signs of an invisible black hole that's devouring everything nearby. "It is within the realm of possibilities that it is already detectable in radio and X-ray and optical," says Han. "We just haven't looked at the right place."

Ignoring Protests, Christie's Holds AI Art Auction, Makes Big Money (cnet.com) 52

As Christie's auction house planned the first-ever auction dedicated to AI-generated art works, over 5,600 people signed an online letter urging them to cancel it. "Many of the artworks you plan to auction were created using AI models that are known to be trained on copyrighted work without a license," the letter complained.

"These models, and the companies behind them, exploit human artists, using their work without permission or payment to build commercial AI products that compete with them. Your support of these models, and the people who use them, rewards and further incentivizes AI companies' mass theft of human artists' work." CNET reports that the signers "range from illustrators to authors to art therapists to cinematographers, from countries all across the globe."

Christie's ignored them all and held the auction anyways. So what happened when it was over on Wednesday morning? More than 30 lots attracted hundreds of bids and brought in $728,784, Christie's reports. And there's a generational twist: The auction house says 37% of registrants were completely new to Christie's, and 48% of bidders were millennials or members of Gen Z... The highest price in the sale was $277,200 for a work by Refik Anadol titled Machine Hallucinations — ISS Dreams — A. It used a data set of more than 1.2 million images taken from the International Space Station and satellites.
ARTnews reports that the auction actually brought in more than Christie's had expected: The sale, which made up of 34 lots, had an 82 percent sell through rate... While some digital artists, including Beeple, championed the sale, others decried it as emblematic of the ongoing struggle between human artistry and machine-driven innovation. The results, however, suggest that AI art — controversial as it may be — is carving a firm place in the market.

Axiom Space and Red Hat Will Bring Edge Computing to the International Space Station (theregister.com) 7

Axiom Space and Red Hat will collaborate to launch Data Center Unit-1 (AxDCU-1) to the International Space Station this spring. It's a small data processing prototype (powered by lightweight, edge-optimized Red Hat Device Edge) that will demonstrate initial Orbital Data Center (ODC) capabilities.

"It all sounds rather grand for something that resembles a glorified shoebox," reports the Register. Axiom Space said: "The prototype will test applications in cloud computing, artificial intelligence, and machine learning (AI/ML), data fusion and space cybersecurity."

Space is an ideal environment for edge devices. Connectivity to datacenters on Earth is severely constrained, so the more processing that can be done before data is transmitted to a terrestrial receiving station, the better. Tony James, chief architect, Science and Space at Red Hat, said: "Off-planet data processing is the next frontier, and edge computing is a crucial component. With Red Hat Device Edge and in collaboration with Axiom Space, Earth-based mission partners will have the capabilities necessary to make real-time decisions in space with greater reliability and consistency...."

The Red Hat Device Edge software used by Axiom's device combines Red Hat Enterprise Linux, the Red Hat Ansible Platform, and MicroShift, a lightweight Kubernetes container orchestration service derived from Red Hat OpenShift. The plan is for Axiom Space to host hybrid cloud applications and cloud-native workloads on-orbit. Jason Aspiotis, global director of in-space data and security, Axiom Space, told The Register that the hardware itself is a commercial off-the-shelf unit designed for operation in harsh environments... "AxDCU-1 will have the ability to be controlled and utilized either via ground-to-space or space-to-space communications links. Our current plans are to maintain this device on the ISS. We plan to utilize this asset for at least two years."

The article notes that HPE has also "sent up a succession of Spaceborne computers — commercial, off-the-shelf supercomputers — over the years to test storage, recovery, and operational potential on long-duration missions." (They apparently use Red Hat Enterprise Linux.) "At the other end of the scale, the European Space Agency has run Raspberry Pi computers on the ISS for years as part of the AstroPi educational outreach program."

Axiom Space says their Orbital Data Center is deigned to "reduce delays traditionally associated with orbital data processing and analysis." By utilizing Earth-independent cloud storage and edge processing infrastructure, Axiom Space ODCs will enable data to be processed closer to its source, spacecraft or satellites, bypassing the need for terrestrial-based data centers. This architecture alleviates reliance on costly, slow, intermittent or contested network connections, creating more secure and quicker decision-making in space.

The goal is to allow Axiom Space and its partners to have access to real-time processing capabilities, laying the foundation for increased reliability and improved space cybersecurity with extensive applications. Use cases for ODCs include but are not limited to supporting Earth observation satellites with in-space and lower latency data storage and processing, AI/ML training on-orbit, multi-factor authentication and cyber intrusion detection and response, supervised autonomy, in-situ space weather analytics and off-planet backup & disaster recovery for critical infrastructure on Earth.

Remembering 'Space Ghost' Voice Actor George Lowe (yahoo.com) 16

Long-time Slashdot reader invisik saw this story on Yahoo News: Comedian and voice actor George Lowe, who is well-known as the voice of Space Ghost on "Space Ghost Coast to Coast," died on March 2. He was 67...

He did some voice-over work for TBWS and Cartoon Network in the 1980s to mid-1990s before getting his lead role of Space Ghost in 1994 with the premiere of "Space Ghost Coast to Coast" on Cartoon Network. Space Ghost was a parody of talk shows with live-action celebrity guests, hosted by the Hanna Barbera character Space Ghost, which aired from 1994 to 1999 on Cartoon Network. The show later returned in 2001, airing on Adult Swim's late-night programming block until 2004, Deadline reported.

When animation pioneer William Hanna died in 2001, Slashdot founder CmdrTaco posted "the thing that I respect most about Hanna is the fact that a show like Space Ghost Coast to Coast was allowed to take their characters and do something truly unique with them. He even lent his voice to the show in one episode. Not a lot of people would be willing to allow one of their creations to be twisted like that, but the original Space Ghost was one of my childhood staples, and Space Ghost Coast to Coast stands in a class all its own proving that creativity isn't dead on TV."

"Adult Swim would not be the network it is today without Space Ghost Coast to Coast," argues ComicBook.com. (And as a tribute to Lowe, Adult Swim posted five minutes of surreal outtakes from Space Ghost Coast to Coast's 10th Anniversary celebration.)

A headline at Vulture.com makes the case that "Space Ghost Coast to Coast Only Worked Because of George Lowe." They've rounded up a collection of videos with surreal titles like "Marrying Bjork" and "Guesting on a MF DOOM track" (plus that time Lowe did a live interview — in his Space Ghost costume — with C-SPAN).

Google Introduces Debian Linux Terminal App For Android (zdnet.com) 43

Google has introduced a Debian Linux terminal app for Android in its ongoing effort to transform Android into a versatile desktop OS. It's initially available on Pixel devices running Android 15 but will be expanded to "all sufficiently robust Android phones" when Android 16 arrives later this year," writes ZDNet's Steven Vaughan-Nichols. An anonymous reader shares an excerpt from the report: Today, Linux is only available on the latest Pixel devices running Android 15. When Android 16 arrives later this year, it's expected that all sufficiently robust Android phones will be able to run Linux. Besides a Linux terminal, beta tests have already shown that you should be able to run desktop Linux programs from your phone -- games like Doom, for example. The Linux Terminal runs on top of a Debian Linux virtual machine. This enables you to access a shell interface directly on your Android device. And that just scratches the surface of Google's Linux Terminal. It's actually a do-it-all app that enables you to download, configure, and run Debian. Underneath Terminal runs the Android Virtualization Framework (AVF). These are the APIs that enable Android devices to run other operating systems.

To try the Linux Terminal app, you must activate Developer Mode by navigating to Settings - About Phone and tapping the build number seven times. I guess Google wants to make sure you want to do this. Once Developer Mode is enabled, the app can be activated via Settings - System - Developer options - Linux development environment. The initial setup may take a while because it needs to download Debian. Typically this is a 500MB download. Once in place, it allows you to adjust disk space allocation, set port controls for network communication, and recover the virtual machine's storage partition. However, it currently lacks support for graphical user interface (GUI) applications. For that, we'll need to wait for Android 16.

According to Android specialist Mishaal Rahman, 'Google wants to turn Android into a proper desktop operating system, and in order to do that, it has to make it work better with traditional PC input methods and display options. Therefore, Google is now testing new external display management tools in Android 16 that bring Android closer to other desktop OSes.'

NASA's SPHEREx Is Poised To Launch Mission To Map 450 Million Galaxies In Color (nbcnews.com) 20

NASA's SPHEREx observatory (short for Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) is set to launch this week to map 450 million galaxies in infrared, providing insights into galaxy formation, the origins of water, and testing theories about the universe's rapid expansion following the Big Bang. The two-year mission will repeatedly survey the entire sky and help scientists understand fundamental cosmic processes. NBC News reports: The launch from Vandenberg Space Force Base in California is scheduled to occur Friday, during a window that opens at 10:09 p.m. ET. Liftoff was initially planned for Feb. 27, but NASA rescheduled it several times, first to "complete vehicle processing and prelaunch checkouts," and because of availability at the California launch site.

The cone-shaped spacecraft -- along with four suitcase-sized satellites that NASA will deploy at the same time on a separate mission to study the sun -- will launch atop a SpaceX Falcon 9 rocket. The $488 million SPHEREx mission, which has been in development for about a decade, is designed to map the celestial sky in 102 infrared colors -- more than any other mission before it, according to NASA.

Athena Spacecraft Declared Dead After Toppling Over On Moon (cnn.com) 47

The Athena lunar lander from Intuitive Machines has prematurely ended its mission after tipping onto its side shortly after touching down near the moon's south pole, failing to fully accomplish its planned water-searching objectives. From a report: Athena was expected to operate for about 10 days before powering down as lunar night fell over the spacecraft's landing site at Mons Mouton, a plateau that lies about 100 miles (160 kilometers) from the south pole. But photographs delivered by the lander before it powered down confirmed the vehicle is lying on its side. "With the direction of the sun, the orientation of the solar panels, and extreme cold temperatures in the crater, Intuitive Machines does not expect Athena to recharge," the company said in a statement. "The mission has concluded and teams are continuing to assess the data collected throughout the mission."

Intuitive Machines, however, highlighted that, although Athena did not operate as intended, the lander was able to briefly operate and transmit data after touchdown. That made the mission the "southernmost lunar landing and surface operations ever achieved." Intuitive Machines also said that Athena was "able to accelerate several program and payload milestones, including NASA's PRIME-1 suite, before the lander's batteries depleted." PRIME-1, which includes a drill that was expected to dig into the lunar surface to hunt for water, was able to move, according to a statement from NASA that states the device "demonstrated the hardware's full range of motion in the harsh environment of space."

Intuitive Machines Lunar Lander Reaches Moon, Status Uncertain 26

Intuitive Machines' Athena lander touched down near the lunar south pole Thursday but may have toppled during landing, jeopardizing its scientific mission. "We're trying to evaluate exactly what happened in that last bit," said Tim Crain, Intuitive Machines' chief technology officer. Data from an inertial measurement unit suggests the 15-foot robotic spacecraft is lying on its side.

The landing issues mirror problems faced by the company's Odysseus spacecraft last year, which also toppled after touchdown. Noisy data from laser altitude instruments likely contributed to the landing complications, officials said. CEO Steve Altemus reported the spacecraft isn't generating expected power, probably because its solar panels are improperly oriented. The company believes Athena landed somewhere on Mons Mouton, though outside the planned landing zone.

The $62.5 million NASA-contracted mission carries several payloads, including a drill to search for frozen water, three small rovers, and a rocket-powered hopping drone. NASA officials indicated some experiments might still function despite the lander's orientation. Intuitive Machines' stock fell 20% Thursday following reports of the spacecraft's problems.

SpaceX's Latest Starship Test Flight Ends With Another Explosion (npr.org) 284

SpaceX's eighth Starship test flight ended in failure after losing control and breaking apart shortly after launch, sending debris over Florida. "Starship didn't make it quite as high or as far" as the attempt nearly two months ago," notes NPR. That attempt ended with an explosion that sent flaming debris raining down on the Turks and Caicos. From the report: This time, wreckage from the latest explosion was seen streaming from the skies over Florida. It was not immediately known whether the spacecraft's self-destruct system had kicked in to blow it up. The 403-foot rocket blasted off from Texas. SpaceX caught the first-stage booster back at the pad with giant mechanical arms, but engines on the spacecraft on top started shutting down as it streaked eastward for what was supposed to be a controlled entry over the Indian Ocean, half a world away. Contact was lost as the spacecraft went into an out-of-control spin.

Starship reached nearly 90 miles in altitude before trouble struck and before four mock satellites could be deployed. It was not immediately clear where it came down, but images of flaming debris were captured from Florida, including near Cape Canaveral, and posted online. The space-skimming flight was supposed to last an hour. "Unfortunately this happened last time too, so we have some practice at this now," SpaceX flight commentator Dan Huot said from the launch site. SpaceX later confirmed that the spacecraft experienced "a rapid unscheduled disassembly" during the ascent engine firing. "Our team immediately began coordination with safety officials to implement pre-planned contingency responses," the company said in a statement posted online.

Gboard Testing Circle, Pill-Shaped Keys On Android (9to5google.com) 36

Google Gboard for Android is introducing circle or pill-shaped keys for some beta testers today. "Instead of the key borders being rounded rectangles, Gboard is switching to circles and pills for letters, while the space bar and other keys are now pill-shaped," reports 9to5Google. "While there should be no functional change to touch targets, these new shapes really shift the look of Gboard for Android." From the report: On paper, it's a bit more modern (and rounded) compared to what came before. However, it's a bit cramped if you have "Long press for symbols" enabled, which goes from the top-right corner to being directly above the letter. The physical analog Gboard is moving away from is how most keys on laptops and desktops are square.

NASA is Making Sacrifices To Keep the Voyager Mission Alive (theverge.com) 28

NASA has begun shutting down science instruments aboard the twin Voyager spacecraft to extend their 47-year journey through interstellar space, officials said. Voyager 1's cosmic ray subsystem was deactivated on February 25, while Voyager 2's low-energy charged particle instrument will be shut down on March 24. Both spacecraft will then operate with just three of their original ten science instruments.

The radioisotope power systems aboard the Voyagers lose approximately 4 watts annually, threatening to end their mission within months without intervention. "Electrical power is running low," said Voyager project manager Suzanne Dodd. "The Voyagers have been deep space rock stars since launch, and we want to keep it that way as long as possible." NASA engineers believe these measures could enable the probes to continue operating into the 2030s, far beyond their initial five-year design life.

Could New Clocks Keep Airplanes Safe From GPS Jamming? (bbc.com) 98

Geoffrey.landis writes: Over the last three months of 2024, more than 800 cases of GPS interference were recorded in Lithuanian airspace. Estonia and Finland have also raised concerns, accusing Russia of deploying technology to jam satellite navigation signals near Nato's eastern flank.

A group of British scientists -- dubbed the "Time Lords" -- are working on a solution: to develop portable atomic clocks. By carrying a group of atoms cooled to -273C on the plane itself, rather than relying on an external signal, the technology can't be interfered with by jamming. But the problem is that the equipment is still too large to be used routinely on planes.

The UK Hub for Quantum Enabled Position Navigation and Timing (QEPNT) was set up last December by the government to shrink the devices on to a chip, making them robust enough for everyday life and affordable for everyone. Henry White, part of the team from BAE Systems that worked on the test flight, told BBC News that he thought the first application could be aboard ships, "where there's a bit more space".

NASA Uses GPS On the Moon For the First Time (popsci.com) 30

An anonymous reader quotes a report from Popular Science: On March 2, Firefly Aerospace's Blue Ghost made history, becoming the first commercial lunar lander to successfully touchdown on the moon's surface. The groundbreaking lander is wasting no time in getting to work. According to NASA, the joint public-private mission has already successfully demonstrated the ability to use Earth-based GPS signals on the lunar surface, marking a major step ahead of future Artemis missions. Accurate and reliable navigation will be vital for future astronauts as they travel across the moon, but traditional GPS tools aren't much good when you're around 225,000 miles from Earth. One solution could be transmitting data from the Global Navigation Satellite System (GNSS) to the lunar surface in order to autonomously measure time, velocity, and position. That's what mission engineers from NASA and the Italian Space Agency hoped to demonstrate through the Lunar GNSS Receiver Experiment (LuGRE), one of the 10 projects packed aboard Blue Ghost. [...]

"On Earth we can use GNSS signals to navigate in everything from smartphones to airplanes," Kevin Coggins, deputy associate administrator for NASA's SCaN (Space Communications and Navigation) Program, said in a statement. "Now, LuGRE shows us that we can successfully acquire and track GNSS signals at the Moon." LuGRE relied on two GNSS constellations, GPS and Galileo, which triangulate positioning based on dozens of medium Earth orbit satellites that provide real-time tracking data. It performed its navigational fix at approximately 2 a.m. EST on March 3, while about 225,000 miles from Earth. Blue Ghost's LuGRE system will continue collecting information over the next two weeks almost continuously while the lander's other tools begin their own experiments.
