alternative_right shares a report from ScienceDaily: Southwest Research Institute led a James Webb Space Telescope (JWST) survey, discovering a previously unknown tiny moon orbiting Uranus. A team led by SwRI's Dr. Maryame El Moutamid discovered the small object in a series of images taken on Feb. 2, 2025, bringing Uranus' total moon count to 29. "As part of JWST's guest observer program, we found a previously unknown satellite of the ice giant, which has been provisionally designated S/2025 U 1," said El Moutamid, a lead scientist in SwRI's Solar System Science and Exploration Division in Boulder, Colorado. "This object, by far the smallest object discovered to date, was detected in a series of 10 long exposures obtained by the Near-Infrared Camera."

Located in the outer solar system, Uranus is the seventh planet from the Sun. Known as "the sideways planet" for its extreme axial tilt, the cyan-colored ice giant has a deep atmosphere composed of hydrogen, helium and methane. Scientists think Uranus' larger moons are roughly equal parts water ice and silicate rock. "Assuming that the new moon has an albedo comparable to other nearby satellites, this object is probably around six miles (10 km) in diameter," El Moutamid said. "It is well below the detection threshold for the Voyager 2 cameras."

After five months on the International Space Station, four astronauts splashed down in the Pacific Ocean in a SpaceX Crew Dragon capsule named Endurance, reports Space.com.

It was NASA's 10th commercial crew rotation mission: The flight launched atop a SpaceX Falcon 9 rocket on March 14 and arrived at the orbiting lab two days later. Crew-10's four astronauts soon set to conducting science work, which consumed much of their time over the ensuing months... The wheels for Crew-10's departure began turning last Saturday (Aug. 2), when SpaceX's four-person Crew-11 mission arrived at the International Space Station. The Crew-10 astronauts spent a few days advising their replacements, then set their minds to gearing up for the return to Earth — and reflecting on their orbital experience.

"We got to accomplish a lot of really amazing operational things," Ayers said during a farewell ceremony on Tuesday (Aug. 5). "We got to see some amazing views, and we have had some really big belly laughs and a wonderful time together," she added. "I think that [we're] leaving with a heart full of gratitude, and [we're] excited to see where the International Space Station goes after we get home." The hatches between Endurance and the ISS closed on Friday (Aug. 8) at 4:20 p.m. EDT (2020 GMT), and the capsule undocked about two hours later, at 6:15 p.m. EDT (2205 GMT). Endurance then began maneuvering its way back to Earth, setting up its splashdown today.

It was the first Pacific Ocean return for a SpaceX CCP mission; all previous such flights have come down off the Florida coast. SpaceX recently shifted to West Coast reentries for all of its Dragon missions, both crewed and uncrewed, to minimize the chance that falling space debris could damage property or injure people.
"During their mission, crew members traveled nearly 62,795,205 million miles," NASA announced, "and completed 2,368 orbits around Earth..." Along the way, Crew-10 contributed hundreds of hours to scientific research, maintenance activities, and technology demonstrations. McClain, Ayers, and Onishi completed investigations on plant and microalgae growth, examined how space radiation affects DNA sequences in plants, observed how microgravity changes human eye structure and cells in the body, and more. The research conducted aboard the orbiting laboratory advances scientific knowledge and demonstrates new technologies that enable us to prepare for human exploration of the Moon and Mars.

McClain and Ayers also completed a spacewalk on May 1, relocating a communications antenna, beginning the installation of a mounting bracket for a future International Space Station Roll-Out Solar Array, and other tasks.

Jim Lovell, the legendary NASA astronaut who commanded the Apollo 13 "successful failure" mission, has died at age 97. From a report: Lovell was already well-known among NASA astronauts, having flown to space on the Gemini 7, Gemini 12 and Apollo 8 missions, before he was selected to command Apollo 13, which would have marked the third successful crewed moon landing for NASA. But during the ill-fated mission -- which carried Lovell as well as astronauts John Swigert Jr. and Fred Haise Jr. on board -- an oxygen tank located on the crew's service module exploded when they were about 200,000 miles (322,000 kilometers) away from Earth.

Lovell delivered the news to mission control, saying "Houston, we've had a problem." With the damage effectively taking out the crew's power source and other life support supplies, the Apollo 13 crew had to abruptly abandon their trek to the lunar surface and use several engine burns to swing around the far side of the moon and put themselves on a course back toward Earth. The three-person crew made a high-stakes splashdown return in the South Pacific Ocean about three days after the tank explosion, marking the conclusion of what has come to be known as the "successful failure" of the Apollo missions. The ordeal was fictionalized in Ron Howard's 1995 film "Apollo 13." [...]

Lovell was the first astronaut to make four spaceflights, totaling more than 715 hours in space. He was part of NASA's second-ever astronaut class, selected in September 1962 and nicknamed the "New Nine." And joining the Apollo 13 crew after having first served on Apollo 8, which intentionally circumnavigated the moon but did not land on its surface, made Lovell the first human ever to see the moon up close for a second time.

NASA's Lunar Trailblazer mission ended prematurely after losing contact with the satellite just one day post-launch, the agency announced today. Engadget reports: The NASA satellite was part of the IM-2 mission by Intuitive Machines, which took off from a SpaceX Falcon 9 rocket from Kennedy Space Center on February 26 at 7:16PM ET. The Lunar Trailblazer successfully separated from the rocket as planned about 48 minutes after launch. Operators in Pasadena, CA established communication with the satellite at 8:13PM ET, but two-way communication was lost the next day and the team was unable to recover the connection. From the limited data ground teams received before the satellite went dark, the craft's solar arrays were not correctly positioned toward the sun, which caused its batteries to drain. "While it was not the outcome we had hoped for, mission experiences like Lunar Trailblazer help us to learn and reduce the risk for future, low-cost small satellites to do innovative science as we prepare for a sustained human presence on the Moon," said Nicky Fox, associate administrator at NASA Headquarters' Science Mission Directorate. "Thank you to the Lunar Trailblazer team for their dedication in working on and learning from this mission through to the end."

An anonymous reader quotes a report from Politico: Transportation Secretary Sean Duffy will announce expedited plans this week to build a nuclear reactor on the moon, the first major action by the former Fox News host as the interim NASA administrator. NASA has discussed building a reactor on the lunar surface, but this would set a more definitive timeline -- according to documents obtained by POLITICO -- and come just as the agency faces a massive budget cut. [...] The reactor directive orders the agency to solicit industry proposals for a 100 kilowatt nuclear reactor to launch by 2030, a key consideration for astronauts' return to the lunar surface. NASA previously funded research into a 40 kilowatt reactor for use on the moon, with plans to have a reactor ready for launch by the early 2030s.

The first country to have a reactor could "declare a keep-out zone which would significantly inhibit the United States," the directive states, a sign of the agency's concern about a joint project China and Russia have launched. The directive also orders NASA to designate a leader for the effort and to get industry input within 60 days. The agency is seeking companies able to launch a reactor by 2030 since that's around the time China intends to land its first astronaut on the moon. The nuclear initiative means that NASA will continue to have a hand in nuclear development even after the Pentagon's recent cancellation of a joint program on nuclear-powered rocket engines. "While the budget did not prioritize nuclear propulsion, that wasn't because nuclear propulsion is seen as a non-worthy technology," the NASA official said.

In Shanghai at the World Artificial Intelligence Conference (which ran until Tuesday), the Chinese government "announced an international organization for AI regulation and a 13-point action plan aimed at fostering global cooperation to ensure the technology's beneficial and responsible development," reports the Washington Post.

The theme of the conference was "Global Solidarity in the AI Era," the article notes, and "the expo is one part of Beijing's bid to establish itself as a responsible AI leader for the international community."

CNN points out that China's announcement comes "just days after the United States unveiled its own plan to promote U.S. dominance." Chinese Premier Li Qiang unveiled China's vision for future AI oversight at the World AI Conference, an annual gathering in Shanghai of tech titans from more than 40 countries... While Li did not directly refer to the U.S. in his speech, he alluded to the ongoing trade tensions between the two superpowers, which include American restrictions on advanced semiconductor exports — a component vital for powering and training AI, which is currently causing a shortage in China. "Key resources and capabilities are concentrated in a few countries and a few enterprises," said Li in his speech on Saturday. "If we engage in technological monopoly, controls and restrictions, AI will become an exclusive game for a small number of countries and enterprises...."

Secretary-General of the Association of Southeast Asian Nations, Dr. Kao Kim Hourn, also called for "robust governance" of artificial intelligence to mitigate potential threats, including misinformation, deepfakes, and cybersecurity threats... Former Google CEO Eric Schmidt reiterated the call for international collaboration, explicitly calling on the U.S. and China to work together... "We have a vested interest to keep the world stable, keep the world not at war, to keep things peaceful, to make sure we have human control of these tools."
China's plan "called for establishing an international open-source community," reports the Wall Street Journal, "through which AI models can be freely deployed and improved by users." Industry participants said that plan "showed China's ambition to set global standards for AI and could undermine the U.S., whose leading models aren't open-source... While the world's best large language model is still American, the best model that everyone can use free is now Chinese."

"The U.S. should commit to ensuring that powerful models remain openly available," argues an opinion piece in The Hill by Stability AI's former head of public policy. Ubiquity is a matter of national security: retreating behind paywalls will leave a vacuum filled by strategic adversaries. Washington should treat open technology not as a vector for Chinese Communist Party propaganda but as a vessel to transmit U.S. influence abroad, molding the global ecosystem around U.S. industry. If DeepSeek is China's open-source "Sputnik moment," we need a legislative environment that supports — not criminalizes — an American open-source Moon landing.

An anonymous reader quotes a report from Ars Technica: Silicon Valley's AI talent war just reached a compensation milestone that makes even the most legendary scientific achievements of the past look financially modest. When Meta recently offered AI researcher Matt Deitke $250 million over four years (an average of $62.5 million per year)—with potentially $100 million in the first year alone -- it shattered every historical precedent for scientific and technical compensation we can find on record. [Meta CEO Mark Zuckerberg reportedly also offered an unnamed AI engineer $1 billion in compensation to be paid out over several years.] That includes salaries during the development of major scientific milestones of the 20th century. [...]

To put these salaries in a historical perspective: J. Robert Oppenheimer, who led the Manhattan Project that ended World War II, earned approximately $10,000 per year in 1943. Adjusted for inflation using the US Government's CPI Inflation Calculator, that's about $190,865 in today's dollars -- roughly what a senior software engineer makes today. The 24-year-old Deitke, who recently dropped out of a PhD program, will earn approximately 327 times what Oppenheimer made while developing the atomic bomb. [...] The Apollo program offers another striking comparison. Neil Armstrong, the first human to walk on the moon, earned about $27,000 annually -- roughly $244,639 in today's money. His crewmates Buzz Aldrin and Michael Collins made even less, earning the equivalent of $168,737 and $155,373, respectively, in today's dollars. Current NASA astronauts earn between $104,898 and $161,141 per year. Meta's AI researcher will make more in three days than Armstrong made in a year for taking "one giant leap for mankind." The report notes that the sums being offered to some of these AI researchers top even the most popular sports athletes. "The New York Times noted that Steph Curry's most recent four-year contract with the Golden State Warriors was $35 million less than Deitke's Meta deal (although soccer superstar Cristiano Ronaldo will make $275 million this year as the highest-paid professional athlete in the world)," reports Ars.

Measuring earth's position (or "geodesy") requires using telescopes that track radiation from distant black holes. Their signals "pass cleanly through the atmosphere and we can receive them during day and night and in all weather conditions," writes a senior scientist at the University of Tasmania.

But there's a problem... Radio waves are also used for communication on Earth — including things such as wifi and mobile phones... [A] few narrow lanes are reserved for radio astronomy. However, in previous decades the radio highway had relatively little traffic. Scientists commonly strayed from the radio astronomy lanes to receive the black hole signals. To reach the very high precision needed for modern technology, geodesy today relies on more than just the lanes exclusively reserved for astronomy.

In recent years, human-made electromagnetic pollution has vastly increased. When wifi and mobile phone services emerged, scientists reacted by moving to higher frequencies. However, they are running out of lanes. Six generations of mobile phone services (each occupying a new lane) are crowding the spectrum... Today, the multitude of signals are often too strong for geodetic observatories to see through them to the very weak signals emitted by black holes. This puts many satellite services at risk.

To keep working into the future — to maintain the services on which we all depend — geodesy needs some more lanes on the radio highway. When the spectrum is divided up via international treaties at world radio conferences, geodesists need a seat at the table. Other potential fixes might include radio quiet zones around our essential radio telescopes. Work is also underway with satellite providers to avoid pointing radio emissions directly at radio telescopes. Any solution has to be global. For our geodetic measurements, we link radio telescopes together from all over the world, allowing us to mimic a telescope the size of Earth. The radio spectrum is primarily regulated by each nation individually, making this a huge challenge.

But perhaps the first step is increasing awareness. If we want satellite navigation to work, our supermarkets to be stocked and our online money transfers arriving safely, we need to make sure we have a clear view of those black holes in distant galaxies — and that means clearing up the radio highway.

Remember asteroid 2024 YR4 (which at one point had a 1 in 32 chance of hitting Earth, before ending up at "impact probability zero")? CNN reports that asteroid is now "zooming beyond the reach of telescopes on its orbit around the sun."

"But as scientists wait for it to reappear, its revised trajectory is now drawing attention to another possible target: the moon." The latest observations of the asteroid in early June, before YR4 disappeared from view, have improved astronomers' knowledge of where it will be in seven years by almost 20%, according to NASA. That data shows that even with Earth avoiding direct impact, YR4 could still pose a threat in late 2032 by slamming into the moon. ["The asteroid's probability of impacting the Moon has slightly increased from 3.8% to 4.3%," writes NASA, and "it would not alter the Moon's orbit."]
CNN calls the probabiliy "small but decent enough odds for scientists to consider how such a scenario might play out." The collision could create a bright flash that would be visible with the naked eye for several seconds, according to Wiegert, lead author of a recent paper submitted to the American Astronomical Society journals analyzing the potential lunar impact. The collision could create an impact crater on the moon estimated at 1 kilometer wide (0.6 miles wide), Wiegert said... It would be the largest impact on the moon in 5,000 years and could release up to 100 million kilograms (220 million pounds) of lunar rocks and dust, according to the modeling in Wiegert's study... Particles the size of large sand grains, ranging from 0.1 to 10 millimeters in size, of lunar material could reach Earth between a few days and a few months after the asteroid strike because they'll be traveling incredibly fast, creating an intense, eye-catching meteor shower, Wiegert said.

"There's absolutely no danger to anyone on the surface," Wiegert said. "We're not expecting large boulders or anything larger than maybe a sugar cube, and our atmosphere will protect us very nicely from that. But they're traveling faster than a speeding bullet, so if they were to hit a satellite, that could cause some damage...." Hundreds to thousands of impacts from millimeter-size debris could affect Earth's satellite fleet, meaning satellites could experience up to 10 years' equivalent of meteor debris exposure in a few days, Wiegert said... While a temporary loss of communication and navigation from satellites would create widespread difficulties on Earth, Wiegert said he believes the potential impact is something for satellite operators, rather than the public, to worry about.
"Any missions in low-Earth orbit could also be in the pathway of the debris, though the International Space Station is scheduled to be deorbited before any potential impact," reports CNN.

And they add that Wiegert also believes even small pieces of debris (tens of centimeters in size) "could present a hazard for any astronauts who may be present on the moon, or any structures they have built for research and habitation... The moon has no atmosphere, so the debris from the event could be widespread on the lunar surface, he added."

Conspiracy theorists drastically overestimate how many people share their beliefs, according to a study published in the Personality and Social Psychology Bulletin. Researchers conducted eight studies involving over 4,000 US adults and found that while participants believed conspiracy claims just 12% of the time, believers thought they were in the majority 93% of the time.

The study examined beliefs about claims such as the Apollo Moon landings being faked and Princess Diana's death not being an accident. In one example, 8% of participants believed the Sandy Hook shooting was a false flag operation, but that group estimated 61% of people agreed with them. "It might be one of the biggest false consensus effects that's been observed," said co-author Gordon Pennycook, a psychologist at Cornell University. The findings suggest overconfidence serves as a primary driver of conspiracy beliefs.

An anonymous reader quotes a report from Phys.org: The mission team of NASA's Jupiter-orbiting Juno spacecraft executed a deep-space move in December 2023 to repair its JunoCam imager to capture photos of the Jovian moon Io. Results from the long-distance save were presented during a technical session on July 16 at the Institute of Electrical and Electronics Engineers Nuclear & Space Radiation Effects Conference in Nashville. JunoCam is a color, visible-light camera. The optical unit for the camera is located outside a titanium-walled radiation vault, which protects sensitive electronic components for many of Juno's engineering and science instruments. This is a challenging location because Juno's travels carry it through the most intense planetary radiation fields in the solar system. While mission designers were confident JunoCam could operate through the first eight orbits of Jupiter, no one knew how long the instrument would last after that. Throughout Juno's first 34 orbits (its prime mission), JunoCam operated normally, returning images the team routinely incorporated into the mission's science papers. Then, during its 47th orbit, the imager began showing hints of radiation damage. By orbit 56, nearly all the images were corrupted.

While the team knew the issue might be tied to radiation, pinpointing what was specifically damaged within JunoCam was difficult from hundreds of millions of miles away. Clues pointed to a damaged voltage regulator that was vital to JunoCam's power supply. With few options for recovery, the team turned to a process called annealing, where a material is heated for a specified period before slowly cooling. Although the process is not well understood, the idea is that heating can reduce defects in the material. Soon after the annealing process finished, JunoCam began cranking out crisp images for the next several orbits. But Juno was flying deeper and deeper into the heart of Jupiter's radiation fields with each pass. By orbit 55, the imagery had again begun showing problems.

"After orbit 55, our images were full of streaks and noise," said JunoCam instrument lead Michael Ravine of Malin Space Science Systems. "We tried different schemes for processing the images to improve the quality, but nothing worked. With the close encounter of Io bearing down on us in a few weeks, it was Hail Mary time: The only thing left we hadn't tried was to crank JunoCam's heater all the way up and see if more extreme annealing would save us." Test images sent back to Earth during the annealing showed little improvement in the first week. Then, with the close approach of Io only days away, the images began to improve dramatically. By the time Juno came within 930 miles (1,500 kilometers) of the volcanic moon's surface on Dec. 30, 2023, the images were almost as good as the day the camera launched, capturing detailed views of Io's north polar region that revealed mountain blocks covered in sulfur dioxide frosts rising sharply from the plains and previously uncharted volcanoes with extensive flow fields of lava. To date, the solar-powered spacecraft has orbited Jupiter 74 times. Recently, the image noise returned during Juno's 74th orbit.

An anonymous reader shared this report from Cosmos magazine about a plan to "pick up those faint signals from billions of years ago." Astronomers are planning to launch a tiny spacecraft to the far side of the Moon to listen out for "ancient whispers" in a quest to uncover the secrets of the early universe. The mission will focus on understanding the 'Cosmic Dawn', a period in the early stages of the universe after the Big Bang but before the first stars and galaxies appeared.

One of the difficulties in studying this period of the universe is that silence is essential. With all the electronics and interference in our atmosphere, Earth becomes too loud, making it unsuitable for this kind of research... The proposed mission will utilise the Moon as a giant shield, blocking out the noise from Earth, in order to observe these signals...

The mission, known as CosmoCube, is a joint study between the UK's University of Portsmouth, University of Cambridge and Rutherford Appleton Laboratory Space... CosmoCube's radio will operate at low frequencies (10-100MHz), which should hopefully be able to detect extremely faint signals. The team hope to reach lunar orbit before the end of the decade, with a roughly 5-year roadmap planned.
The article includes this quote from Professor David Bacon, from the University of Portsmouth and CosmoCube researcher. "It's incredible how far these radio waves have travelled, now arriving with news of the universe's history.

"The next step is to go to the quieter side of the Moon to hear that news."

An anonymous reader shares a report: This week has seen the shortest days of the year so far. According to data from the U.S. Naval Observatory and the International Earth Rotation and Reference Systems Service, Tuesday's rotation was about 1.34 milliseconds less than 24 hours. More quick spins are expected this week, later this month and in early August, according to predictions from the website Time and Date.

This isn't completely out of the ordinary: Our world's spins have been faster than usual lately. The average day has mostly shortened over the past decade, and within the past five years or so, the full rotation has clocked in at a hair less than 24 hours more often than not. Factors driving the change include movements at Earth's core, atmospheric changes and the moon's position.

But long-term trends do not suggest that the days will shorten in perpetuity. In fact, it is just the opposite. For many millenniums, the days have been growing longer. A Tyrannosaurus rex that lived 70 million years ago would have experienced an average daily rotation of about 23 1/2 hours, studies have found.

"For-profit companies are pushing the narrative that they can do space inexpensively," writes Slashdot reader RUs1729 in response to an opinion piece from SpaceNews. "Their track record reveals otherwise: cutting corners won't do it for the foreseeable future." Here's an excerpt from the article, written by Robert N. Eberhart: The headlines in the space industry over the past month have delivered a sobering reminder: space is not forgiving, and certainly not friendly to overpromising entrepreneurs. From iSpace's second failed lunar landing attempt (making them 0 for 2) to SpaceX's ongoing Starship test flight setbacks -- amid a backdrop of exploding prototypes and shifting goalposts -- the evidence is mounting that the commercialization of space is not progressing in the triumphant arc that press releases might suggest. This isn't just a series of flukes. It points to a structural, strategic and cultural problem in how we talk about innovation, cost and success in space today.

Let's be blunt: 50 years ago, we did this. We sent humans to the moon, not once but repeatedly, and brought them back. With less computational power than your phone, using analog systems and slide rules, we achieved feats of incredible precision, reliability and coordination. Today's failures, even when dressed up as "learning opportunities," raises the obvious question: Why are we struggling to do now what we once achieved decades ago with far more complexity and far less technology?

Until very recently, the failure rate of private lunar exploration efforts underscored this reality. Over the past two decades, not a single private mission had fully succeeded -- until last March when Firefly Aerospace's Blue Ghost lander touched down on the moon. It marked the first fully successful soft landing by a private company. That mission deserves real credit. But that credit comes with important context: It took two decades of false starts, crashes and incomplete landings -- from Space IL's Beresheet to iSpace's Hakuto-R and Astrobotic's Peregrine -- before even one private firm delivered on the promise of lunar access. The prevailing industry answer -- "we need to innovate for lower cost" -- rings hollow. What's happening now isn't innovation; it's aspiration masquerading as disruption... "This is not a call for a retreat to Cold War models or Apollo-era budgets," writes Eberhart, in closing. "It's a call for seriousness. If we're truly entering a new space age, then it needs to be built on sound engineering, transparent economics and meaningful technical leadership -- not PR strategy. Let's stop pretending that burning money in orbit is a business model."

"The dream of a sustainable, entrepreneurial space ecosystem is still alive. But it won't happen unless we stop celebrating hype and start demanding results. Until then, the real innovation we need is not in spacecraft -- it's in accountability."

Robert N. Eberhart, PhD, is an associate professor of management and the faculty director of the Ahlers Center for International Business at the Knauss School of Business of University of San Diego. He is the author of several academic publications and books. He is also part of Oxford University's Smart Space Initiative and contributed to Berkeley's Space Sciences Laboratory. Before his academic career, Prof. Eberhart founded and ran a successful company in Japan.

"When Apollo astronauts stumbled across shimmering orange beads on the moon, they had no idea they were gazing at ancient relics of violent volcanic activity," writes ScienceDaily. These glass spheres, tiny yet mesmerizing, formed billions of years ago during fiery eruptions that launched molten droplets skyward, instantly freezing in space. Now, using advanced instruments that didn't exist in the 1970s, scientists have examined the beads in unprecedented detail. The result is a remarkable window into the moon's dynamic geological history, revealing how eruption styles evolved and how lunar conditions once mirrored explosive events we see on Earth today...

Analyses of orange and black lunar beads have shown that the style of volcanic eruptions changed over time. "It's like reading the journal of an ancient lunar volcanologist," said Ryan Ogliore [an associate professor of physics at Missouri's Washington University, which has a large repository of lunar samples that were returned to Earth].
"The beads are tiny, pristine capsules of the lunar interior..." says Ogliore. "We've had these samples for 50 years, but we now have the technology to fully understand them..."

"The very existence of these beads tells us the moon had explosive eruptions, something like the fire fountains you can see in Hawaii today."

"NASA engineers have spent the past decade developing a rugged, partially autonomous lander designed to explore Europa, one of Jupiter's most intriguing moons," reports Gizmodo.

But though NASA "got cold feet over the project," the engineers behind the project are now suggesting the probe could instead explore Enceladus, the sixth-largest moon of Saturn: Europa has long been a prime target in the search for extraterrestrial biology because scientists suspect it harbors a subsurface ocean beneath its icy crust, potentially teeming with microbial life. But the robot — packed with radiation shielding, cutting-edge software, and ice-drilling appendages — won't be going anywhere anytime soon.

In a recent paper in Science Robotics, engineers at NASA's Jet Propulsion Laboratory (JPL) outlined the design and testing of what was once the Europa Lander prototype, a four-legged robotic explorer built to survive the brutal surface conditions of the Jovian moon. The robot was designed to walk — as opposed to roll — analyze terrain, collect samples, and drill into Europa's icy crust — all with minimal guidance from Earth, due to the major communication lag between our planet and the moon 568 million miles (914 million kilometers) away. Designed to operate autonomously for hours at a time, the bot came equipped with stereoscopic cameras, a robotic arm, LED lights, and a suite of specialized materials tough enough to endure harsh radiation and bone-chilling cold....

According to the team, the challenges of getting to Europa — its radiation exposure, immense distance, and short observation windows — proved too daunting for NASA's higher-ups. And that's before you take into consideration the devastating budget cuts planned by the Trump administration, which would see the agency's funding fall from $7.3 billion to $3.9 billion. The lander, once the centerpiece of a bold astrobiology initiative, is now essentially mothballed.

But the engineers aren't giving up. They're now lobbying for the robot to get a second shot — on Enceladus, Saturn's ice-covered moon, which also boasts a subsurface ocean and has proven more favorable for robotic exploration. Enceladus is still frigid, but `has lower radiation and better access windows than Europa.

Japan-based Ispace confirmed its Resilience lander likely crashed during its second failed attempt at a lunar landing, after a sensor malfunction prevented proper deceleration. Despite the setback, the company remains committed to future missions, with funding secured for a third attempt using a new lander, Apex 1.0, scheduled for 2027. "Until then, Ispace has its work cut out for it," reports CNN. "[Ispace CEO and founder Takeshi Hakamada] said during the news briefing he will need to work to regain the trust of investors, and the company will need to deeply investigate what went wrong on the Resilience mission to ensure similar issues don't plague Apex 1.0."

The company has ambitious "plans to eventually build a city on the lunar surface that would house a thousand people and welcome thousands more for tourist visits," notes ABC News. "If ispace is going to establish a colony on the moon, it will need to identify an ample supply of ice or water, which it will convert into fuel for a future lunar fueling station. The ability to produce fuel on the moon will enable the company to transport people back and forth between the Earth and the moon."

In December it looked like NASA's next administrator would be the billionaire businessman/space enthusiast who twice flew to orbit with SpaceX.

But Saturday the nomination was withdrawn "after a thorough review of prior associations," according to an announcement made on social media. The Guardian reports: His removal from consideration caught many in the space industry by surprise. Trump and the White House did not explain what led to the decision... In [Isaacman's] confirmation hearing in April, he sought to balance Nasa's existing moon-aligned space exploration strategy with pressure to shift the agency's focus on Mars, saying the US can plan for travel to both destinations. As a potential leader of Nasa's 18,000 employees, Isaacman faced a daunting task of implementing that decision to prioritize Mars, given that Nasa has spent years and billions of dollars trying to return its astronauts to the moon...

Some scientists saw the nominee change as further destabilizing to Nasa as it faces dramatic budget cuts without a confirmed leader in place to navigate political turbulence between Congress, the White House and the space agency's workforce.
"It was unclear whom the administration might tap to replace Isaacman," the article adds, though "One name being floated is the retired US air force Lt Gen Steven Kwast, an early advocate for the creation of the US Space Force..."

Ars Technica notes that Kwast, a former Lieutenant General in the U.S. Air Force, has a background that "seems to be far less oriented toward NASA's civil space mission and far more focused on seeing space as a battlefield — decidedly not an arena for cooperation and peaceful exploration."

"Future moon astronauts may find water more accessible than previously thought," writes Space.com, citing a new NASA-led experiment: Because the moon lacks a magnetic field like Earth's, the barren lunar surface is constantly bombarded by energetic particles from the sun... Li Hsia Yeo, a planetary scientist at NASA's Goddard Space Flight Center in Maryland, led a lab experiment observing the effects of simulated solar wind on two samples of loose regolith brought to Earth by the Apollo 17 mission... To mimic conditions on the moon, the researchers built a custom apparatus that included a vacuum chamber, where the samples were placed, and a tiny particle accelerator, which the scientists used to bombard the samples with hydrogen ions for several days.

"The exciting thing here is that with only lunar soil and a basic ingredient from the sun — which is always spitting out hydrogen — there's a possibility of creating water," Yeo said in a statement. "That's incredible to think about." Supporting this idea, observations from previous moon missions have revealed an abundance of hydrogen gas in the moon's tenuous atmosphere. Scientists suspect that solar-wind-driven heating facilitates the combination of hydrogen atoms on the surface into hydrogen gas, which then escapes into space. This process also has a surprising upside, the new study suggests. Leftover oxygen atoms are free to bond with new hydrogen atoms formed by repeated bombardment of the solar wind, prepping the moon for more water formation on a renewable basis.

The findings could help assess how sustainable water on the moon is, as the sought-after resource is crucial for both life support and as propellant for rockets. The team's study was published in March in the journal JGR Planets .
NASA created a fascinating animation showing how water is released from the Moon during meteor showers. (In 2016 scientists discovered that when speck of comet debris vaporize on impact, they create shock waves in the lunar soil which can sometimes breach the dry upper layer, releasing water molecules from the hydrated layer below...)

Longtime Slashdot reader AmiMoJo shares a report from the BBC: China will let scientists from six countries, including the U.S., examine the rocks it collected from the Moon -- a scientific collaboration that comes as the two countries remain locked in a bitter trade war. Two NASA-funded U.S. institutions have been granted access to the lunar samples collected by the Chang'e-5 mission in 2020, the China National Space Administration (CNSA) said on Thursday. CNSA chief Shan Zhongde said that the samples were "a shared treasure for all humanity," local media reported.

Chinese researchers have not been able to access NASA's Moon samples because of restrictions imposed by U.S. lawmakers on the space agency's collaboration with China. Under the 2011 law, Nasa is banned from collaboration with China or any Chinese-owned companies unless it is specifically authorized by Congress. But John Logsdon, the former director of the Space Policy Institute at George Washington University, told BBC Newshour that the latest exchange of Moon rocks have "very little to do with politics." While there are controls on space technology, the examination of lunar samples had "nothing of military significance," he said. "It's international cooperation in science which is the norm."
