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.

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..."

Breakthrough Energy, the climate group founded by Bill Gates, has laid off dozens of employees in the U.S. and Europe, eliminating its public policy and partnerships teams as it shifts away from advocacy work. Its investment and grantmaking divisions will remain unaffected. The Detroit News reports: Breakthrough Energy is an umbrella organization founded by Gates that houses various initiatives aimed at accelerating the clean energy transition. It also encompasses Breakthrough Energy Ventures, one of the biggest investors in early-stage climate technologies with stakes in more than 120 companies, as well as a grantmaking program for early-seed stage company founders and Breakthrough Catalyst, a funding platform focused on emergent climate technologies. None of those divisions of the group were impacted by cuts, which were reported earlier by the New York Times.

[...] "In the United States especially, the conversation about climate has been sidetracked by politics," Gates wrote in the introduction to his 2021 book. "Some days, it can seem as if we have little hope of getting anything done." The climate pullback is happening at the same time as the US cuts foreign aid, a field where Gates is also a major donor. His nonprofit, the Gates Foundation, operates with a budget of billions and has a strong focus on overseas development. "Bill Gates remains as committed as ever to advancing the clean energy innovations needed to address climate change," a Breakthrough Energy spokesperson said in an emailed statement. "His work in this area will continue and is focused on helping drive reliable affordable, clean energy solutions that will enable people everywhere to thrive."

On Wednesday, the EPA announced the agency will "undertake 31 historic actions in the greatest and most consequential day of deregulation in U.S. history..."

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."

A new statistical analysis has identified the films audiences "love to hate," with Battlefield Earth, Morbius, Grease 2, and Cats topping the list of cinema's most detested productions. The study, published by data analyst Daniel Parris, examined review data from MovieLens to calculate both the percentage of one-star reviews and total disapproval magnitude for each release.

A common thread among these widely derided titles: many were adaptations of popular books or shows, or attempted to capitalize on once-beloved franchises. Adam Sandler leads the actors most frequently appearing in widely disliked films, followed by comedians and action stars who have starred in productions with high one-star review rates.

The research also reveals an industry trend toward increasing one-star reviews over time, with family-oriented fare and horror films receiving disproportionately negative ratings despite consistent box office profitability - suggesting studios have prioritized risk-averse, commercially viable projects over critical acclaim.

An anonymous reader quotes a report from TechCrunch: There's a power crunch looming as AI and cloud providers ramp up data center construction. But a new report suggests that a solution lies beneath their foundations. Advanced geothermal power could supply nearly two-thirds of new data center demand by 2030, according to an analysis by the Rhodium Group. The additions would quadruple the amount of geothermal power capacity in the U.S. -- from 4 gigawatts to about 16 gigawatts -- while costing the same or less than what data center operators pay today. In the western U.S., where geothermal resources are more plentiful, the technology could provide 100% of new data center demand. Phoenix, for example, could add 3.8 gigawatts of data center capacity without building a single new conventional power plant.

Geothermal resources have enormous potential to provide consistent power. Historically, geothermal power plants have been limited to places where Earth's heat seeps close to the surface. But advanced geothermal techniques could unlock 90 gigawatts of clean power in the U.S. alone, according to the U.S. Department of Energy. [...] Because geothermal power has very low running costs, its price is competitive with data centers' energy costs today, the Rhodium report said. When data centers are sited similarly to how they are today, a process that typically takes into account proximity to fiber optics and major metro areas, geothermal power costs just over $75 per megawatt hour. But when developers account for geothermal potential in their siting, the costs drop significantly, down to around $50 per megawatt hour.

The report assumes that new generating capacity would be "behind the meter," which is what experts call power plants that are hooked up directly to a customer, bypassing the grid. Wait times for new power plants to connect to the grid can stretch on for years. As a result, behind the meter arrangements have become more appealing for data center operators who are scrambling to build new capacity.

Sphere Entertainment Co, the company behind the Las Vegas Sphere, said they are considering opening scaled-down versions of the immersive venue in other cities. AV Magazine reports: While this has been been feasible for its high-profile residencies such as U2, the Eagles, Dead & Company and Anyma, smaller venues could attract a broader range of artists who might not have the budget or demand to fill the flagship Las Vegas location. By scaling down the size while retaining the signature technology, Sphere Entertainment Co can offer a similar spectacle at a more sustainable cost for artists and spectators.

The possibility of mini-Spheres follows news that a full-scale venue will open in the UAE as a result of a partnership between Sphere Entertainment Co and the Department of Culture and Tourism -- Abu Dhabi. Beyond concerts, the Las Vegas Sphere has proven successful with immersive films such as V-U2: An Immersive Concert Film and the Sphere Expeience featuring Darren Aronofsky's Postcard from Earth, which In January passed 1,000 screenings. "As we enter a new fiscal year, we see significant opportunities to drive our Sphere business forward in Las Vegas and beyond," said Dolan. "We believe we are on a path toward realizing our vision for this next-generation medium and generating long-term shareholder value."

Nearly every country on Earth has dirtier air than doctors recommend breathing, a report has found. From a report: Only seven countries met the World Health Organization's guidelines for tiny toxic particles known as PM2.5 last year, according to analysis from the Swiss air quality technology company IQAir. Australia, New Zealand and Estonia were among the handful of countries with a yearly average of no more than 5ug of PM2.5 per cubic metre, along with Iceland and some small island states.

The most polluted countries were Chad, Bangladesh, Pakistan, the Democratic Republic of the Congo and India. PM2.5 levels in all five countries were at least 10 times higher than guideline limits in 2024, the report found, stretching as much as 18 times higher than recommended levels in Chad. Doctors say there are no safe levels of PM2.5, which is small enough to slip into the bloodstream and damage organs throughout the body, but have estimated millions of lives could be saved each year by following their guidelines. Dirty air is the second-biggest risk factor for dying after high blood pressure.

An anonymous reader quotes a report from The Guardian: The pollution of the planet by microplastics is significantly cutting food supplies by damaging the ability of plants to photosynthesize, according to a new assessment. The analysis estimates that between 4% and 14% of the world's staple crops of wheat, rice and maize is being lost due to the pervasive particles. It could get even worse, the scientists said, as more microplastics pour into the environment. About 700 million people were affected by hunger in 2022. The researchers estimated that microplastic pollution could increase the number at risk of starvation by another 400 million in the next two decades, calling that an "alarming scenario" for global food security. [...]

The new study, published in the journal Proceedings of the National Academy of Sciences, combined more than 3,000 observations of the impact of microplastics on plants, taken from 157 studies. Previous research has indicated that microplastics can damage plants in multiple ways. The polluting particles can block sunlight reaching leaves and damage the soils on which the plants depend. When taken up by plants, microplastics can block nutrient and water channels, induce unstable molecules that harm cells and release toxic chemicals, which can reduce the level of the photosynthetic pigment chlorophyll. The researchers estimated that microplastics reduced the photosynthesis of terrestrial plants by about 12% and by about 7% in marine algae, which are at the base of the ocean food web. They then extrapolated this data to calculate the reduction in the growth of wheat, rice and maize and in the production of fish and seafood.

Asia was hardest hit by estimated crop losses, with reductions in all three of between 54 million and 177 million tons a year, about half the global losses. Wheat in Europe was also hit hard as was maize in the United States. Other regions, such as South America and Africa, grow less of these crops but have much less data on microplastic contamination. In the oceans, where microplastics can coat algae, the loss of fish and seafood was estimated at between 1m and 24m tonnes a year, about 7% of the total and enough protein to feed tens of millions of people.

The US will be "central" to solving the climate crisis despite Donald Trump's withdrawal of government support and cash, the president of the next UN climate summit has said. From a report: Andre Correa do Lago, president-designate of the Cop30 summit for the host country, Brazil, hinted that businesses and other organisations in the US could play a constructive role without the White House. "We have no idea of ignoring the US," he told journalists on a call on Friday. "The US is a key country in this exercise. There is the US government, which will limit its participation [but] the US is a country with such amazing technology, amazing innovation -- this is the US that can contribute. The US is a central country for these discussions and solutions."

Brazil has also vowed to hold an "ethical stocktake" aimed at examining climate justice issues, for poor and vulnerable people, and to give Indigenous people a key role at the talks. Correa do Lago wrote to all UN countries on Monday, setting out Brazil's expectations that all governments will draw up national plans for steep cuts in greenhouse gas emissions before the conference starts in Belem, a rainforest city at the mouth of the Amazon, in November.

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 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.

Global sea ice fell to a record low in February, scientists have said, a symptom of an atmosphere fouled by planet-heating pollutants. From a report: The combined area of ice around the north and south poles hit a new daily minimum in early February and stayed below the previous record for the rest of the month, the EU's Copernicus Climate Change Service (C3S) said on Thursday. "One of the consequences of a warmer world is melting sea ice," said the C3S deputy director, Samantha Burgess. "The record or near-record low sea ice cover at both poles has pushed global sea ice cover to an all-time minimum."

The agency found the area of sea ice hit its lowest monthly level for February in the Arctic, at 8% below average, and its fourth-lowest monthly level for February in the Antarctic, at 26% below average. Its satellite observations stretch back to the late 1970s and its historical observations to the middle of the 20th century. Scientists had already observed an extreme heat anomaly in the north pole at the start of February, which caused temperatures to soar more than 20C above average and cross the threshold for ice to melt. They described the latest broken record as "particularly worrying" because ice reflects sunlight and cools the planet. The agency found the area of sea ice hit its lowest monthly level for February in the Arctic, at 8% below average, and its fourth-lowest monthly level for February in the Antarctic, at 26% below average. Its satellite observations stretch back to the late 1970s and its historical observations to the middle of the 20th century.

Half of the world's climate-heating carbon emissions come from the fossil fuels produced by just 36 companies, analysis has revealed. From a report: The researchers said the 2023 data strengthened the case for holding fossil fuel companies to account for their contribution to global heating. Previous versions of the annual report have been used in legal cases against companies and investors.

The report found that the 36 major fossil fuel companies, including Saudi Aramco, Coal India, ExxonMobil, Shell and numerous Chinese companies, produced coal, oil and gas responsible for more than 20bn tonnes of CO2 emissions in 2023. If Saudi Aramco was a country, it would be the fourth biggest polluter in the world after China, the US and India, while ExxonMobil is responsible for about the same emissions as Germany, the world's ninth biggest polluter, according to the data.

Global emissions must fall by 45% by 2030 if the world is to have a good chance of limiting temperature rise to 1.5C, the internationally agreed target. However, emissions are still rising, supercharging the extreme weather that is taking lives and livelihoods across the planet. The International Energy Agency has said new fossil fuel projects started after 2021 are incompatible with reaching net zero emissions by 2050. Most of the 169 companies in the Carbon Majors database increased their emissions in 2023, which was the hottest year on record at the time.

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.

AmiMoJo shares a report: Europe's biggest battery storage project has entered commercial operation in Scotland [alternative source], promising to soak up surplus wind power and prevent turbines being paid to switch off.

Zenobe said the first phase of its project at Blackhillock, between Inverness and Aberdeen, was now live with capacity to store enough power to supply 200 megawatts of electricity for two hours. It is due to be expanded to 300 megawatts by next year, enough to supply 3.1 million homes, more than every household in Scotland.

The government's Clean Power 2030 action plan sets a target capacity of up to 27 gigawatts of batteries by 2030, a sixfold increase from the 4.5 gigawatts installed today. This huge expansion is seen as critical as Britain builds more renewable wind and solar power, since batteries can store surplus generation for use when the wind does not blow and the sun does not shine.

An anonymous reader quotes a report from TechCrunch: Google has open sourced an AI model, SpeciesNet, designed to identify animal species by analyzing photos from camera traps. Researchers around the world use camera traps -- digital cameras connected to infrared sensors -- to study wildlife populations. But while these traps can provide valuable insights, they generate massive volumes of data that take days to weeks to sift through. In a bid to help, Google launched Wildlife Insights, an initiative of the company's Google Earth Outreach philanthropy program, around six years ago. Wildlife Insights provides a platform where researchers can share, identify, and analyze wildlife images online, collaborating to speed up camera trap data analysis.

Many of Wildlife Insights' analysis tools are powered by SpeciesNet, which Google claims was trained on over 65 million publicly available images and images from organizations like the Smithsonian Conservation Biology Institute, the Wildlife Conservation Society, the North Carolina Museum of Natural Sciences, and the Zoological Society of London. Google says that SpeciesNet can classify images into one of more than 2,000 labels, covering animal species, taxa like "mammalian" or "Felidae," and non-animal objects (e.g. "vehicle"). SpeciesNet is available on GitHub under an Apache 2.0 license, meaning it can be used commercially largely sans restrictions.

Earth's core "burns with an estimated forty-four trillion watts of power," the New Yorker reminds us — enough to "satisfy the entire world's energy needs" with a power source that's carbon-free, ubiquitous — and unlimited. (Besides running 24 hours a day, one of geothermal energy's key advantages is "it can be used for both electricity and heating, which collectively account for around 38% of global climate emissions...")

And one drilling expert tells them there's been an "exponential spin-up of activity in geothermal" energy projects over the last two years. (Ironically it was the fracking boom also brought an "explosion of new drilling practices — such as horizontal drilling and magnetic sensing — that inspired a geothermal resurgence.") In 2005 one research team calculated that just 2% of the heat just four miles underground in America "could meet the entire country's energy needs — two thousand times over," according to the article.

So their new article checks in on the progress of geothermal energy projects around the world, including a Utah company using a diamond-bit drill to dig nearly a mile into the earth to install a 150-ton steel tube surrounded by special heat-resistant cement — all to create "a massive straw" for transporting hot water (and steam). The biggest problem is drilling miles through hot rock, safely. If scientists can do that, however, next-generation geothermal power could supply clean energy for eons... At 6:15 P.M. on May 3rd, cement had started flowing into the hole. Four hours later, part of the cement folded in on itself. The next morning, the cement supply ran out; the men had miscalculated how much they needed. This brought the three-hundred-million-dollar operation to a maddening halt... The cement truck from Bakersfield arrived around 8:30 P.M. By ten-thirty, the men were pouring cement again, gluing the enormous metal straw in place. Next, the team scanned the borehole with gamma rays...

"Thousands of buildings across the United States are staying cool with the help of cutting-edge batteries made from one of the world's simplest materials," reports the Washington Post — ice. When electricity is cheap, the batteries freeze water. When energy costs go up, building managers turn off their pricey chillers and use the ice to keep things cool. A typical building uses about a fifth of its electricity for cooling, according to the International Energy Agency. By shifting their energy use to cheaper times of day, the biggest buildings can save hundreds of thousands of dollars a year on their power bills. They can also avoid using electricity from the dirtiest fossil fuel plants. In places where the weather is hot and energy prices swing widely throughout the day — for instance, Texas, Southern California and most of the American Southwest — buildings could cut their power bills and carbon emissions by as much as a third, experts say...

When every building is blasting its air conditioner at the same moment on a hot day, power companies often fire up backup generators, known as peaker plants, which are generally extra pricey and polluting. If utilities avoid using peaker plants, they'll pollute less and save money. Last year, the Energy Department struck a tentative $306 million loan deal with the ice-battery-maker Nostromo Energy to install its systems in 193 California buildings to make energy cheaper and cleaner while lowering the state's blackout risk.
"The batteries themselves are huge..." the article acknowledges, citing one in New York City that uses 100 parking spot-sized tanks "which collectively make 3 million margaritas' worth of ice each night... But that's starting to change." (And they believe new smaller designs "could bring the batteries into smaller buildings and even houses.") Wherever they can squeeze into the market, ice batteries could be a cheaper and longer-lasting option than the lithium-ion batteries that power phones, cars and some buildings because their main ingredient is water, experts say. The pricey chemicals in a lithium-ion cell might degrade after 10 years, but water never wears out.
And according to the article, one company has already installed ice batteries in over 4,000 buildings...

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...
