Watch the "Blue Ghost" lunar lander attempt its moon landing.

The actual landing is scheduled to happen at 3:34 a.m. Eastern time, according to CNN, while "The first images from the mission should be delivered about a half hour after..." Success is not guaranteed... [B]roadly speaking, about half of all lunar landing attempts have ended in failure. Jason Kim, Firefly's CEO, told CNN in December that his company's experience building rockets has given him a high degree of confidence in Blue Ghost's propulsion systems. "We're using (reaction control system) thrusters that we've built, developed in-house, that are designed by the same people that design our rocket engines. That reduces risk," Kim said. "All that gives us high confidence when we have people that do rocket engines really, really well — some of the best in the world."
But the New York Times notes that Blue Ghost, built by Austin, Texas-based Firefly Aerospace, is just one of three robotic spacecraft "in space right now that are aiming to set down on the moon's surface." Blue Ghost has performed nearly perfectly. For the first 25 days, it circled Earth as the company turned on and checked the spacecraft's systems. It then fired its engine on a four-day journey toward the moon, entering orbit on February 13. The spacecraft's cameras have recorded close-up views of the moon's cratered surface...

On the same SpaceX Falcon 9 rocket that launched Blue Ghost to orbit was Resilience, a lunar lander built by Ispace of Japan. The two missions are separate, but Ispace, seeking a cheaper ride to space, had asked SpaceX for a rideshare, that is, hitching a ride as a secondary payload... Although Resilience launched at the same time as Blue Ghost, it is taking a longer, more fuel-efficient route to the moon and is expected to enter orbit around the moon in early May.
The third lunar lander heading to the moon is Athena (from Intuitive Machines), which launched Thursday on a SpaceX Falcon 9 rocket, "marking the first time humanity has had three lunar landers en route to the Moon at the same time," according to a statement from the company. Space.com notes that "To date, just one private spacecraft has ever landed successfully on the moon — Intuitive Machines' Odysseus, which did so in February 2024." Athena launched with several other spacecraft last night, including Odin, a scouting probe built by the asteroid-mining company Astroforge, and NASA's water-hunting Lunar Trailblazer. Lunar Trailblazer is also moon-bound, though it's headed for orbit rather than the surface...

Hidden layers of rock below the surface of Mars "strongly suggest" the presence of an ancient ocean, according to an international team of scientists including researchers at Penn State.

From the university's announcement: The new research offers the clearest evidence yet that the planet once contained a significant body of water and a more habitable environment for life, according to Benjamin Cardenas, assistant professor of geology at Penn State and co-author on the study. "We're finding places on Mars that used to look like ancient beaches and ancient river deltas," Cardenas said. "We found evidence for wind, waves, no shortage of sand — a proper, vacation-style beach."

The Zhurong rover landed on Mars in 2021 in an area known as Utopia Planitia and sent back data on the geology of its surroundings in search of signs of ancient water or ice. Unlike other rovers, it came equipped with rover-penetrating radar, which allowed it to explore the planet's subsurface, using both low and high-frequency radar to penetrate the Martian soil and identify buried rock formations. By studying the underground sedimentary deposits, scientists are able to piece together a more complete picture of the red planet's history, Cardenas explained. When the team reviewed radar data, it revealed a similar layered structure to beaches on Earth: formations called "foreshore deposits" that slope downwards towards oceans and form when sediments are carried by tides and waves into a large body of water.

"This stood out to us immediately because it suggests there were waves, which means there was a dynamic interface of air and water," Cardenas said. "When we look back at where the earliest life on Earth developed, it was in the interaction between oceans and land, so this is painting a picture of ancient habitable environments, capable of harboring conditions friendly toward microbial life." When the team compared the Martian data with radar images of coastal deposits on Earth, they found striking similarities, Cardenas said. The dip angles observed on Mars fell right within the range of those seen in coastal sedimentary deposits on Earth...

The study also provided new information on the evolution of the Martian environment, suggesting that a life-friendly warm and wet period spanned potentially tens of millions of years.
Mars "was evolving," Cardenas says in the announcement. "Rivers were flowing, sediment was moving, and land was being built and eroded.

"This type of sedimentary geology can tell us what the landscape looked like, how they evolved, and, importantly, help us identify where we would want to look for past life."

CNN notes that the research was published Monday in the journal Proceedings of the National Academy of Sciences.

More than 100,000 seeds from across Africa have been deposited in the Svalbard Global Seed Vault, the world's repository for specimens intended to preserve crop diversity in the event of disaster. From a report: Among the latest additions are seeds critical to building climate resilience, such as the tree Faidherbia albida, which turns nitrogen into ammonia and nitrates, and Cordia africana, the Sudan teak, a tree renowned for its strength and durability. The seeds, from 177 different species, were delivered to the Norwegian vault on Tuesday by Dr Eliane Ubalijoro, the chief executive of the Center for International Forestry Research and World Agroforestry (Cifor-Icraf).

"For me, seeds are about hope," Ubalijoro said. "They're about moving beyond survival, particularly when you come from places that have gone through really difficult times. When I think of my country of Rwanda and what happened in 1994, seed banks were critical when it came to rebuilding after the genocide." Ubalijoro said countries that had experienced disaster and conflict could emerge as leaders in the fight against climate breakdown.

Asteroid 2024 YR4, once considered a significant impact risk, has been reassigned to Torino Scale Level Zero and therefore poses no hazard to Earth. "The NASA JPL Center for Near-Earth Object Studies (CNEOS) now lists the 2024 YR4 impact probability as 0.00005 (0.005%) or 1-in-20,000 for its passage by Earth in 2032," Richard Binzel, Professor of Planetary Science at the Massachusetts Institute of Technology (MIT) and creator of the Torino scale exclusively told Space.com. "That's impact probability zero folks!" From the report: Discovered in Dec. 2024, 2024 YR4 quickly climbed to the top of NASA's Sentry Risk table, at one point having a 1 in 32 chance of hitting Earth. This elevated it to Level 3 on the Torino scale, a system used since 1999 to categorize potential Earth impact events. Level 3, which falls within the yellow band of the Torino Scale, is described as: "A close encounter, meriting attention by astronomers. Current calculations give a 1% or greater chance of collision capable of localized destruction."

This conforms to the second part of the Torino scale level 3 description, which states: "Most likely, new telescopic observations will lead to re-assignment to Level 0. Attention by public and by public officials is merited if the encounter is less than a decade away." "Asteroid 2024 YR4 has now been reassigned to Torino Scale Level Zero, the level for 'No Hazard' as additional tracking of its orbital path has reduced its possibility of intersecting the Earth to below the 1-in-1000 threshold," Binzel continued. "1-in-1000 is the threshold established for downgrading to Level 0 for any object smaller than 100 meters; YR4 has an estimated size of 164 feet (50 meters)."

[...] While 2024 YR4 poses no threat, it will still have a major scientific impact when it passes Earth in 2028 and again in 2032. On Dec. 17, the asteroid will come to within 5 million miles of Earth. Then, on Dec.22, 2032, 2024 YR4 will pass within just 167,000 miles of our planet. For context, the moon is 238,855 miles away.

More than half the world's countries have no plans to protect 30% of land and sea for nature, despite committing to a global agreement to do so less than three years ago, new analysis shows. From a report: In late 2022, nearly every country signed a once-in-a-decade UN deal to halt the destruction of Earth's ecosystems. It included a headline target to protect nearly a third of the planet for biodiversity by the end of the decade -- a goal known as "30 by 30." But as country leaders gather in Rome to conclude Cop16 negotiations to save nature, analysis of countries' plans by Carbon Brief and the Guardian found that many countries are will fall short. More than half are either pledging to protect less than 30% of their territory or are not setting a numerical target.

The Los Angeles Times publishes a weekly "Boiling Point" newsletter about climate change and energy issues. And this week they examined whether the scientific fact of a change climate is reflected in the mass media: For the second year running, nonprofit consulting firm Good Energy applied its Climate Reality Check to the actual Oscar-nominated films [which] tests whether a movie and its characters acknowledge global warming... Of last year's 13 Oscar-nominated films that met Good Energy's criteria (feature-length movies set in present-day or near-future Earth) three passed the test. This year, there were 10 eligible films. Only "The Wild Robot" passed...

Maybe a few years from now, studios will release a torrent of movies and shows reflecting the realities of a scary-but-still-salvageable world, helmed by producers and writers jolted into renewed awareness by the infernos. But for now, the picture is bleak. A peer-reviewed study slated for publication this month, led by Rice University English and environmental studies professor Matthew Schneider-Mayerson, analyzes climate change mentions in 250 of the most popular movies of the last decade. The authors found that just 12.8% of the films allude to global warming. Just 3.6% depict or mention the climate crisis in two or more scenes. "A lot of times, it's really being mentioned in passing," Schneider-Mayerson said...

[Good Energy Chief Executive Anna Jane Joyner] pointed to another analysis led by Schneider-Mayerson, which found that movies passing the Climate Reality Check and released in theaters earned 10% more at the box office, on average, than films failing the test. Netflix, meanwhile, says on its website that 80% of its customers "choose to watch at least one story on Netflix that helps them better understand climate issues or highlight hopeful solutions around sustainability...." [Netflix's "Sustainability Stories" collection includes Dr. Seuss' The Lorax, Chicken Run: Dawn of the Nugget, and Waterworld]

Sponsors are interested in selling audiences on climate-friendly products, too. I was sitting in a movie theater last weekend enjoying "Captain America: Brave New World" — the latest entry in Disney's Marvel Cinematic Universe — when, to my surprise, Sam Wilson (Anthony Mackie) got out of his SUV and pulled his iconic red-white-and-blue shield out of the front trunk. Yes, a front trunk, where an internal combustion engine would normally be. That meant Captain America was driving an electric vehicle, right? Indeed, he was. I did some research after I got home and learned that Wilson was driving a GMC Hummer EV, the result of a paid partnership between Marvel Studios and GMC parent company General Motors.
Ironically, the movie does not at any point acknowledge global warming, the article points out (adding "Also, SUVs kill more pedestrians and cyclists than smaller cars.")

"But the more movies and TV shows spotlight climate solutions — electric vehicles, solar panels, induction stoves — the more likely people are to support those solutions. For Hollywood, that's a step in the right direction."

Long-time Slashdot reader schwit1 shared this observation from space/science news blogger Robert Zimmerman: Having now reached lunar orbit in preparation for its landing on March 2, 2025, an engineering test instrument on Firefly's Blue Ghost lunar lander has now proven that even from that distance spacecraft can use the multiple GPS-type satellites in Earth orbit to track their position.

[From NASA.gov]: The Lunar GNSS Receiver Experiment (LuGRE) acquired and tracked Global Navigation Satellite System (GNSS) signals for the first time in lunar orbit – a new record! This achievement, peaking at 246,000 miles, suggests that Earth-based Global Navigation Satellite System constellations can be used for navigation in transit to, around, and potentially on the Moon. It also demonstrates the power of using multiple GNSS constellations together, such as GPS and Galileo, to perform navigation.

After lunar landing, LuGRE will operate for 14 days and attempt to break another record – first reception of GNSS signals on the lunar surface.

This test is a very big deal. It tells us that operations on the Moon, at least those on the near side, will likely not require a GPS-type infrastructure in lunar orbit, thus allowing a lot of difficult missions to proceed sooner while saving a lot of money and time.

An anonymous reader shared this report from ABC News: Elon Musk called this week for the deorbiting of the International Space Station (ISS) "as soon as possible." "It is time to begin preparations for deorbiting the [ISS]," Musk wrote in a post on X on Thursday. "It has served its purpose. There is very little incremental utility. Let's go to Mars." In a follow-up post, Musk said he was planning to recommend to President Donald Trump that the station be brought down "as soon as possible" and that the 2030 timeline for deorbiting be moved up to two years from now.
Jordan Bimm, space historian and professor of science communication at the University of Chicago, told ABC News what he thinks was one of the most important findings to come out of ISS research: "that microgravity affects the body in lots of deleterious ways." "That leads to your bone loss, muscle loss, changes in the fluid inside our bodies that are normally being pulled down by Earth's gravity, changes to the eye and vision loss and things like that. We have gotten good data on how that progresses over time, and importantly, we have developed countermeasures for these things as well, including resistance training or running on a treadmill, things like that..."

"An international research collaboration led by the University of Surrey's Nuclear Physics Group has overturned the long-standing belief that the atomic nucleus of lead-208 is perfectly spherical," reports Phys.org.

They add that the discovery "challenges fundamental assumptions about nuclear structure and has far-reaching implications for our understanding of how the heaviest elements are formed in the universe..." [A] new study published in Physical Review Letters used a high-precision experimental probe to examine its shape and found that rather than being perfectly spherical, the nucleus of lead-208 is slightly elongated, resembling a rugby ball (prolate spheroid)... Using the state-of-the-art GRETINA gamma-ray spectrometer at Argonne National Laboratory in Illinois, U.S., scientists bombarded lead atoms with high-speed particle beams accelerated to 10% of the speed of light — equivalent to circling the Earth every second. The interactions created unique gamma-ray fingerprints of the properties of excited quantum states in lead-208 nuclei — in other words, the nuclei were energized — which, in turn, were used to determine its shape.

Theoretical physicists, including those at the Surrey Nuclear Theory Group, are now re-examining the models used to describe atomic nuclei, as the experiments suggest that nuclear structure is far more complex than previously thought.

The U.S. Space Force released the first-ever public image of its secretive X-37B space plane in orbit, captured during its ongoing seventh mission that launched on December 28, 2023. Space.com reports: The photo, released on Thursday (Feb. 20), was taken by a camera onboard the X-37B while the secretive space plane orbited high above the African continent. One of the plane's solar panels is visible on the left side of the photo, while what appears to be its open payload bay is visible along the top edge. The vehicle has been in orbit for well over a year now, having launched on its seventh mission on Dec. 28, 2023 atop a SpaceX Falcon Heavy rocket.

And now, the X-37B has notched another milestone with the Space Force's release of this photo, the first-ever image of this space plane in orbit that has been shown to the public. While the photo contains scant details about the vehicle and what it's currently testing, it offers a look at Earth far in the background, revealing just how high the vehicle is flying on its seventh mission. We've gotten only one other glimpse at the X-37B in orbit prior to this. During the livestream of its most recent launch, a brief shot of the spacecraft deploying from Falcon Heavy's upper stage was seen while its service module was still attached.

Melting glaciers have caused almost 2cm of sea level rise this century alone, a decades-long study has revealed. From a report: The research shows the world's glaciers collectively lost 6.542tn tonnes of ice between 2000 and 2023, causing an 18mm (0.7in) rise in global sea levels. The world's glaciers lost an average of 273bn tonnes of ice every year -- the equivalent of 30 years of water consumption by the entire global population.

The assessment, led by scientists from the University of Edinburgh and the University of Zurich, found that so far this century, glaciers have lost approximately 5% of their total volume. Regional losses were highly variable; the Antarctic and subantarctic islands lost 2% of their volume but central Europe's glaciers lost 39%.

"These numbers are staggering. They serve as a reminder that things are changing fast in some regions," said Prof Noel Gourmelen, the co-lead author of the study and personal chair of Earth observation at the University of Edinburgh's school of geosciences. A stark contrast in the amount of ice lost each decade was also discovered, with 36% more ice having melted between 2012 and 2023 compared with the previous decade.

The SS United States, a historic ocean liner that once held the transatlantic speed record of 36 knots (41 mph / 66 kph), has departed Philadelphia to be transformed into the world's largest artificial reef off Florida's Gulf Coast. The move is part of a $10 million project to boost tourism by creating a unique diving attraction while preserving the ship's legacy as a symbol of American innovation and engineering. The Associated Press reports: The SS United States, a 1,000-foot vessel that shattered the transatlantic speed record on its maiden voyage in 1952, is being towed to Mobile, Alabama, for planned prep work before officials eventually sink it off Florida's Gulf Coast. The move comes about four months after the conservancy that oversees the ship and its landlord resolved a years-old rent dispute. Officials initially planned to move the vessel last November, but that was delayed due to concerns from the U.S. Coast Guard that the ship wasn't stable enough to make the trip.

Officials in Okaloosa County on Florida's coastal Panhandle hope it will become a barnacle-encrusted standout among the county's more than 500 artificial reefs and a signature diving attraction that could generate millions of dollars annually in local tourism spending for scuba shops, charter fishing boats and hotels. Officials have said the deal to buy the ship could eventually cost more than $10 million. The lengthy process of cleaning, transporting and sinking the vessel is expected to take at least one-and-a-half years.

An anonymous reader quotes a report from Ars Technica: Astronomers have detected over 5,800 confirmed exoplanets. One extreme class is ultra-hot Jupiters, of particular interest because they can provide a unique window into planetary atmospheric dynamics. According to a new paper published in the journal Nature, astronomers have mapped the 3D structure of the layered atmosphere of one such ultra-hot Jupiter-size exoplanet, revealing powerful winds that create intricate weather patterns across that atmosphere. A companion paper published in the journal Astronomy and Astrophysics (PDF) reported on the unexpected identification of titanium in the exoplanet's atmosphere as well. [...]

This latest research relied on observational data collected by the European South Observatory's (ESO) Very Large Telescope, specifically, a spectroscopic instrument called ESPRESSO that can process light collected from the four largest VLT telescope units into one signal. The target exoplanet, WASP-121b -- aka Tylos -- is located in the Puppis constellation about 900 light-years from Earth. One year on Tylos is equivalent to just 30 hours on Earth, thanks to the exoplanet's close proximity to its host star. Since one side is always facing the star, it is always scorching, while the exoplanet's other side is significantly colder.

Those extreme temperature contrasts make it challenging to figure out how energy is distributed in the atmospheric system, and mapping out the 3D structure can help, particularly with determining the vertical circulation patterns that are not easily replicated in our current crop of global circulation models, per the authors. For their analysis, they combined archival ESPRESSO data collected on November 30, 2018, with new data collected on September 23, 2023. They focused on three distinct chemical signatures to probe the deep atmosphere (iron), mid-atmosphere (sodium), and shallow atmosphere (hydrogen). "What we found was surprising: A jet stream rotates material around the planet's equator, while a separate flow at lower levels of the atmosphere moves gas from the hot side to the cooler side. This kind of climate has never been seen before on any planet," said Julia Victoria Seidel of the European Southern Observatory (ESO) in Chile and the Observatoire de la Cote d'Azur in France. "This planet's atmosphere behaves in ways that challenge our understanding of how weather works -- not just on Earth, but on all planets. It feels like something out of science fiction."

An anonymous reader shares a report: Later this month, Intuitive Machines, the private company behind the first commercial lander that touched down on the moon, will launch a second lunar mission from NASA's Kennedy Space Center. The plan is to deploy a lander, a rover, and hopper to explore a site near the lunar south pole that could harbor water ice, and to put a communications satellite on lunar orbit. But the mission will also bring something that's never been installed on the moon or anywhere else in space before -- a fully functional 4G cellular network.

Point-to-point radio communications, which need a clear line of sight between transmitting and receiving antennas, have always been a backbone of both surface communications and the link back to Earth, starting with the Apollo program. Using point-to-point radio in space wasn't much of an issue in the past because there never have been that many points to connect. Usually, it was just a single spacecraft, a lander, or a rover talking to Earth. And they didn't need to send much data either. "They were based on [ultra high frequency] or [very high frequency] technologies connecting a small number of devices with relatively low data throughput," says Thierry Klein, president of Nokia Bell Labs Solutions Research, which was contracted by NASA to design a cellular network for the moon back in 2020.

"A robotic lander from Texas-based Firefly Aerospace is now in orbit around the Moon," reports Spaceflight Now, "and going through its final preparations to land in the coming weeks." Its arrival comes nearly a month after the spacecraft launched onboard a Falcon 9 rocket from pad 39A at NASA's Kennedy Space Center. This is the third mission launched as part of the agency's Commercial Lunar Payload Services (CLPS) program, an initiative designed to bring science and technology demonstrations to the Moon at a cheaper cost...

Manifested on this lander are 10 NASA payloads, which cover a range of objectives. Those include the Lunar Instrumentation for Subsurface Thermal Exploration with Rapidity (LISTER) instrument, which will drill between 2- to 3-meters into the Moon's surface to study the heat flow; and the Stereo Cameras for Lunar Plume-Surface Studies (SCALPSS) 1.1 instrument, which will use a series of cameras to capture the plume generated at landing to help create a three-dimensional model... "We saw that for the type of advanced scientific or engineering measurements we wanted to make, the instruments were small enough and compact enough that we could actually fly 10," [said Joel Kearns, deputy associate administrator for Exploration in NASA's Science Mission Directorate], "if someone could actually schedule them to get all of their operations done over the 14 Earth day lunar daytime."

Firefly Aerospace ended up winning that bid and carries with it the most NASA instruments manifested on a single Commercial Lunar Payload Services lander so far.
Friday on X.com Firefly Aerospace wished a happy Valentine's Day to "all those on Earth who dare to Dream Big."

"Blue Ghost has been capturing stunning imagery of our planet throughout its journey," Spaceflight Now says in a 12-minute video.

And Friday on X.com Firefly posted Blue Ghost's first spectacular shots of the moon as it approaches — along with its special message for Valentine's Day. "I love you to the Moon, but not back — I'm staying there."

An anonymous reader shared this report from the Guardian: Thousands of artists are urging the auction house Christie's to cancel a sale of art created with artificial intelligence, claiming the technology behind the works is committing "mass theft". The Augmented Intelligence auction has been described by Christie's as the first AI-dedicated sale by a major auctioneer and features 20 lots with prices ranging from $10,000 to $250,000...

The British composer Ed Newton-Rex, a key figure in the campaign by creative professionals for protection of their work and a signatory to the letter, said at least nine of the works appearing in the auction appeared to have used models trained on artists' work. However, other pieces in the auction do not appear to have used such models.

A spokesperson for Christie's said that "in most cases" the AI used to create art in the auction had been trained on the artists' "own inputs".
More than 6,000 people have now signed the letter, which states point-blank that "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." 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. We ask that, if you have any respect for human artists, you cancel the auction.
Last week ARTnews spoke to Nicole Sales Giles, Christie's vice-president and director of digital art sales (before the open letter was published). And Giles insisted one of the major themes of the auction is "that AI is not a replacement for human creativity." "You can see a lot of human agency in all of these works," Giles said. "In every single work, you're seeing a collaboration between an AI model, a robot, or however the artist has chosen to incorporate AI. It is showing how AI is enhancing creativity and not becoming a substitute for it."

One of the auction's headline lots is a 12-foot-tall robot made by Matr Labs that is guided by artist Alexander Reben's AI model. It will paint a new section of a canvas live during the sale every time the work receives a bid. Reben told ARTnews that he understands the frustrations of artists regarding the AI debate, but he sees "AI as an incredible tool... AI models which are trained on public data are done so under the idea of 'fair use,' just as search engines once faced scrutiny for organizing book data (which was ultimately found to fall under fair use)," he said.... "AI expands creative potential, offering new ways to explore, remix, and evolve artistic expression rather than replace it. The future of art isn't about AI versus artists — it's about how artists wield AI to push boundaries in ways we've never imagined before...."

Digital artist Jack Butcher has used the open letter to create a minted digital artwork called Undersigned Artists. On X he wrote that the work "takes a collective act of dissent — an appeal to halt an AI art auction — and turns it into the very thing it resists: a minted piece of digital art. The letter, originally a condemnation of AI-generated works trained on unlicensed human labor, now becomes part of the system it critiques."

Christie's will accept cryptocurrency payments for the majority of lots in the sale.

Last June two NASA astronauts flew to the International Space Station on the first crewed test flight of Boeing's Starliner. But they aren't stranded there, and they weren't abandoned, the astronauts reminded CNN this week in a rare space-to-earth interview: "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," he said...

[NASA astronaut Suni] Williams also reiterated a sentiment she has expressed on several occasions, including in interviews conducted before she left Earth. "Butch and I knew this was a test flight," she told CNN's Cooper, acknowledging the pair has been prepared for contingencies and understood that the stay in space might be extended. "We knew that we would probably find some things (wrong with Starliner) and we found some stuff, and so that was not a surprise," she said.
When Cooper opened the interview by asking the astronauts how they're doing, Williams answers "We're doing pretty darn good, actually," pointing out they had plenty of food and great crew members. And Wilmore added that crews come to the space station on a careful cycle, and "to alter that cycle sends ripple effects all the way down the chain. We would never expect to come back just special for us or anyone unless it was a medical issue or something really out of the circumstances along those lines. So we need to come back and keep the normal cycle going..."

CNN's article notes a new announcement from NASA Tuesday that the astronauts might return a couple weeks early "after opting to change the SpaceX Crew Dragon capsule it will use." That mission's targeted launch date is now March 12.

In the meantime, Williams says in the interview, "We do have some internet connection up here, so we can get some internet live. We've gotten football. It's been this crew's go-to this past fall. Also YouTube or something like that. It's not continuous — it has chunks of time that we get it. And we use that same system also to make phone calls home, so we can talk to our families, and do videoconferences even on the weekends as well. This place is a pretty nice place to live, for the most part."

And they're also "working on with folks on the ground" to test the NASA's cube-shaped, free-flying robotic Astrobees.

A new study reveals that widely used pink wildfire suppressants contain high levels of toxic heavy metals like cadmium, arsenic, and chromium, with concentrations up to 3,000 times above drinking water limits. While the government and chemical makers have long concealed up to 20% of the suppressants' ingredients as "trade secrets," researchers have confirmed their role in environmental pollution, raising concerns over their extensive use in residential areas. The Guardian reports: The suppressants are a mix of water, fertilizer, and undisclosed ingredients, while the pink color comes from added dye to show firefighters where it has been sprayed. Metals are likely used as anti-corrosion agents to prevent the plane's tankers from disintegrating, they authors wrote. The mix works by coating vegetation and lowering the amount of oxygen that could fuel the fire. The substance was dropped by as many as 25 aircraft daily to contain the devastating Los Angeles wildfires, and photos from it vividly convey the trade off, showing homes and property covered in hot pink suppression.

The metal levels in the suppressants meet federal guidelines and the authors were initially most worried about environmental contamination, but the heavy use in residential areas this year raises a new set of concerns, Daniel McCurry, one of the study's co-authors, told the Guardian. "Are the hazardous waste thresholds the appropriate bar for these to clear, or, if they're being used in a massive scale in populated neighborhoods, do we need to get stricter on permissible concentrations of toxic compounds?" McCurry asked. [...] The producer of one of the suppressants has said a new generation of the product is "greener," McCurry said, but he added "until we are able to come across some of this material and test it, we really don't know."

Scientists have found evidence suggesting that Earth's inner core has changed shape over the past 20 years, possibly deforming at its edges due to interactions with the liquid outer core and gravitational forces. The BBC reports: The inner core is usually thought to be shaped like a ball, but its edges may actually have deformed by 100 million or more in height in places, according to Prof John Vidale who led the research. [...] The new analysis looked at seismic wave patterns from earthquakes that repeated in the same location between 1991 and 2023. That helped to show how the inner core is changing over time. Prof Vidale, an earth scientist at the University of Southern California, found more evidence to back up the theory that during those years the inner core slowed down around 2010. But his team also found the evidence of the inner core's changing shape. It appears to be happening at the boundary of the inner and outer core, where the inner core is close to melting point. The liquid flow of the outer core as well as pull from an uneven gravity field may cause deformation. Prof Hrvoje Tkalcic from Australian National University said the findings could allow scientists "to make more informed estimates of some important material properties, such as the viscosity of the inner core, which is one of the least known quantities in modern science."

The research is published in the scientific journal Nature Geoscience.

Europe's Euclid space telescope has captured a rare "Einstein ring," showing light from a distant galaxy bent into a perfect circle by the gravity of another galaxy sitting between Earth and the source, the European Space Agency said.

The phenomenon, spotted around galaxy NGC 6505 some 590 million light-years from Earth, reveals the warping of space predicted by Einstein's theory of relativity. The background galaxy, located 4.42 billion light-years away, appears as a complete ring of light around NGC 6505.

"An Einstein ring as perfect as this is extremely rare," said Open University astronomer Stephen Serjeant. Analysis shows NGC 6505 contains about 11% dark matter, a key focus of Euclid's mission to map the universe.
