An anonymous reader shared this report from CNN: The "world's largest" plant designed to suck planet-heating pollution out of the atmosphere like a giant vacuum began operating in Iceland on Wednesday. "Mammoth" is the second commercial direct air capture plant opened by Swiss company Climeworks in the country, and is 10 times bigger than its predecessor, Orca, which started running in 2021... Climeworks plans to transport the carbon underground where it will be naturally transformed into stone, locking up the carbon permanently... The whole operation will be powered by Iceland's abundant, clean geothermal energy....

Climeworks started building Mammoth in June 2022, and the company says it is the world's largest such plant. It has a modular design with space for 72 "collector containers" — the vacuum parts of the machine that capture carbon from the air — which can be stacked on top of each other and moved around easily. There are currently 12 of these in place with more due to be added over the next few months. Mammoth will be able to pull 36,000 tons of carbon from the atmosphere a year at full capacity, according to Climeworks. That's equivalent to taking around 7,800 gas-powered cars off the road for a year...

All the carbon removal equipment in the world is only capable of removing around 0.01 million metric tons of carbon a year, a far cry from the 70 million tons a year needed by 2030 to meet global climate goals, according to the International Energy Agency [7,000x more]... Jan Wurzbacher, the company's co-founder and co-CEO, said Mammoth is just the latest stage in Climeworks' plan to scale up to 1 million tons of carbon removal a year by 2030 and 1 billion tons by 2050. Plans include potential DAC plants in Kenya and the United States.

"Does a levitating robot train on the moon sound far-fetched?" asks LiveScience.

"NASA doesn't seem to think so, as the agency has just greenlit further funding for a study looking into the concept." The project, called "Flexible Levitation on a Track" (FLOAT), has been moved to phase two of NASA's Innovative Advanced Concepts program (NIAC) , which aims to develop "science fiction-like" projects for future space exploration. The FLOAT project could result in materials being transported across the moon's surface as soon as the 2030s, according to the agency... According to NASA's initial design, FLOAT will consist of magnetic robots levitating over a three-layer film track to reduce abrasion from dust on the lunar surface. Carts will be mounted on these robots and will move at roughly 1 mph (1.61 km/h). They could transport roughly 100 tons (90 metric tons) of material a day to and from NASA's future lunar base.
"A durable, long-life robotic transport system will be critical to the daily operations of a sustainable lunar base in the 2030's," according to NASA's blog post, arguing it could be used to

• Transport moon materials mined to produce on-site resources like water, liquid oxygen, liquid hydrogen, or construction materials

• Transport payloads around the lunar base and to and from landing zones or other outposts

An anonymous reader quotes a report from Ars Technica: There's a fundamental flaw in current car safety tech: It's limited to line of sight. Or, perhaps, line of "sensing" is more accurate, because the way cameras and lidar work is to inspect the perimeter of a vehicle and use predictive algorithms to understand the motion of an object in relation to the motion of the vehicle itself. Which is good, because as carmakers have added elements such as pedestrian and cyclist detection, they're trying to prevent drivers from hurting the most vulnerable road users. And unfortunately this is necessary, because even though 2023 saw a slight reduction in drivers striking cyclists and pedestrians, according to the most recent data from the Governor's Highway Safety Association, since 2019 pedestrian fatalities are still up 14 percent -- and cyclist deaths are up 50 percent since 2010. That doesn't mean lidar and cameras have "failed," but because they rely on what the sensors can pick up, they cannot necessarily ID hazards (and alert drivers) as quickly as we need them to, particularly if that's a cyclist in your lane 300 feet down the road, just over the next rise. Yes, current sensing works well now with figuring out the pace of a traffic jam, and automatic emergency braking can step in to stop your car if you fail to. But for non-automotive obstacles, they're still limited.

For that, we need better tech, which is emerging and is called Connected Vehicle to Everything (C-V2X). The idea isn't that complicated. Boiled down, it's a chipset that operates on a portion of the cellular bandwidth, and vehicles with this tech embedded (say in an e-bike or car) monitor anything with a C-V2X chip as well as broadcast their own location at a pulse of 10 times a second. This precision location system would then warn a driver of a cyclist on the road ahead, even beyond line of sight, and in an emergency -- possibly because a cyclist was right in a car's path -- could prevent a collision. [W]ith C-V2X, you don't need Verizon or ATT or anything like that," explains Audi's Kamal Kapadia. Because it isn't using the cellular network -- it's using a portion of cellular bandwidth to allow direct object, or vehicle-to-vehicle, communication. Audi has been working on C-V2X for nearly a decade, and it's part of a group in the US called the Coalition for Cyclist Safety, which also includes suppliers like Bosch, a tech startup in the space called Spoke Safety, and bike brands such as massive Trek, parts supplier Shimano, more niche bikemakers like Switzerland's Stromer, as well as mega telco suppliers and networks such as Qualcomm, Deutsche Telekom, and TELUS. [...]

Mio Suzuki is Trek Bicycle's director of embedded systems, "and we are exploring all sorts of safety," she says. For instance, Trek recently introduced its own radar tail light, which warns riders of a car approaching rapidly -- Garmin has had similar systems for several years. But Suzuki is intrigued by C-V2X because it offers more advanced warning than rear-facing radar. "And unlike cars, we have a very vulnerable road user so we need to augment our senses and the rider's awareness of the riding environment, because we don't have a big metal shield around us." What Suzuki envisions this direct communication might enable is an e-bike where the rider has a display that would warn a rider "of an imminent danger that's approaching; a car might be coming from the side, but the view of the car is obstructed by a building, so the rider can't see." Franz Reindl is CTO of Stromer, a high-end Swiss brand that only makes e-bikes with very top tech, including ABS brakes. Reindl says they're also studying C-V2X. "Safety is one of our biggest promises, and we need to do everything we can with products and technologies to make it more safe for customers." Right now, only Audi and the VW Group have openly talked about using the tech. "Trek's Suzuki thinks that together, the Coalition and so many bike brands within it do have a strong voice," reports Ars. "She also envisions municipalities deploying the technology, especially around work crews and EMS, which should build broader momentum and pressure on automakers."

Longtime Slashdot reader davidwr shares a report from Space Weather Prediction Center (SWPC): On Thursday, May 9, 2024, the NOAA Space Weather Prediction Center issued a Severe (G4) Geomagnetic Storm Watch. At least five earth-directed coronal mass ejections (CMEs) were observed and expected to arrive as early as midday Friday, May 10, 2024, and persist through Sunday, May 12, 2024. Several strong flares have been observed over the past few days and were associated with a large and magnetically complex sunspot cluster (NOAA region 3664), which is 16 times the diameter of Earth. [The agency notes this is the first time it's issued a G4 watch since January, 2005.] "Geomagnetic storms can impact infrastructure in near-Earth orbit and on Earth's surface, potentially disrupting communications, the electric power grid, navigation, radio and satellite operations," NOAA said. "[The Space Weather Prediction Center] has notified the operators of these systems so they can take protective action." The agency said it will continue to monitor the ongoing storm and "provide additional warnings as necessary."

A visual byproduct of the storm will be "spectacular displays of aurora," also known as the Northern Lights, that could be seen for much of the northern half of the country "as far south as Alabama to northern California," said the NOAA. "Northern Montana, Minnesota, Wisconsin and the majority of North Dakota appear to have the best chances to see it," reports Axios, citing the SWPC's aurora viewline. "Forecast models Friday showed the activity will likely be the strongest from Friday night to Saturday morning Eastern time."

UPDATE 6:54 P.M. EDT: G5 conditions have been observed -- the first time since 2003, says Broadcast Meteorologist James Spann.

This is a developing story. More information is available at spaceweather.gov, Google News, and the NOAA.

An anonymous reader quotes a report from Interesting Engineering: Imagine exploring the intricate world within a single cubic millimeter of human brain tissue. It might seem insignificant, but within that tiny space lies a universe of complexity -- 57,000 individual cells, 230 millimeters of blood vessels, and a staggering 150 million synapses, the junctions where neurons communicate. All this information translates to a mind-boggling 1,400 terabytes of data. That's the kind of groundbreaking achievement researchers from Harvard and Google have just accomplished.

Leading the charge at Harvard is Professor Jeff Lichtman, a renowned expert in brain structure. Partnering with Google AI, Lichtman's team has co-created the most detailed 3D reconstruction of a human brain fragment to date. This intricate map, published in Science, offers an unprecedented view of the human temporal cortex, the region responsible for memory and other higher functions. Envision a piece of brain tissue roughly half the size of a rice grain but magnified to reveal every cell and its web of neural connections in vivid detail. This remarkable feat is the culmination of nearly a decade of collaboration between Harvard and Google. Lichtman's expertise in electron microscopy imaging is combined with Google's cutting-edge AI algorithms. [...]

The newly published map in Science reveals previously unseen details of brain structure. One such discovery is a rare but powerful set of axons, each connected by up to 50 synapses, potentially influencing a significant number of neighboring neurons. The team also encountered unexpected structures, like a small number of axons forming intricate whorls. Since the sample came from a patient with epilepsy, it's unclear if these formations are specific to the condition or simply uncommon occurrences.

Last week, NASA announced it is working with a technology development company on a new propulsion system that could transport humans to Mars in only two months -- down from the current nine month journey required to reach the Red Planet. Gizmodo reports: NASA's Innovative Advanced Concepts (NIAC) program recently selected six promising projects for additional funding and development, allowing them to graduate to the second stage of development. The new "science fiction-like concepts," as described by John Nelson, NIAC program executive at NASA, include a lunar railway system and fluid-based telescopes, as well as a pulsed plasma rocket.

The potentially groundbreaking propulsion system is being developed by Arizona-based Howe Industries. To reach high velocities within a shorter period of time, the pulsed plasma rocket would use nuclear fission -- the release of energy from atoms splitting apart -- to generate packets of plasma for thrust. It would essentially produce a controlled jet of plasma to help propel the rocket through space. Using the new propulsion system, and in terms of thrust, the rocket could potentially generate up to 22,481 pounds of force (100,000 Newtons) with a specific impulse (Isp) of 5,000 seconds, for remarkably high fuel efficiency. [...]

The pulsed plasma rocket would also be capable of carrying much heavier spacecraft, which can be then equipped with shielding against galactic cosmic rays for the crew on board. Phase 2 of NIAC is focused on assessing the neutronics of the system (how the motion of the spacecraft interacts with the plasma), designing the spacecraft, power system, and necessary subsystems, analyzing the magnetic nozzle capabilities, and determining trajectories and benefits of the pulsed plasma rocket, according to NASA.

Computer models have found that recent heat waves in the north Pacific may be due to a large reduction in aerosols emitted by factories in China. The findings have been published in the Proceedings of the National Academy of Sciences. Phys.Org reports: In this new effort, the research team noted that the onset of the heat waves appeared to follow successful efforts by the Chinese government to reduce aerosol emissions from their country's factories. Beginning around 2010, factories and power generating plants in China began dramatically reducing emissions of aerosols such as sulfate, resulting in much cleaner air. Noting that aerosols can act like mirrors floating in the air, reflecting heat from the sun back into space, and also pointing out that earlier research efforts had suggested that massive reductions of aerosols in one place could lead to warming in other places -- they wondered if reductions of aerosols in China might be playing a role in the heat waves that began happening in the north Pacific.

To find out if that might be the case, the team began collecting data and then input it into 12 different computer climate models. They ran them under two conditions -- one where emissions from East Asia remained as they were over the past several decades and one where they dropped in the way they had in reality. They found that the models with no declines did not cause much change elsewhere, whereas those with aerosol drops showed heat waves occurring in the northeast parts of the Pacific Ocean.

The models also showed why -- as less heat was reflected back into space over China, warming of coastal regions in Asia began, resulting in the development of high-pressure systems. That in turn made low-pressure systems in the middle Pacific more intense. And that resulted in the Aleutian Low growing bigger and moving south which weakened the westerly winds that typically cool the sea surface. The result was hotter conditions.

"With all the improvements in car safety over the decades, the recent addition of a plethora of high tech sensors and warnings comes with increased costs," writes longtime Slashdot reader smooth wombat. "And not just to have to have them on your car. Any time you get into an accident, even a minor one, it will most likely require a detailed examination of any sensors which may have been affected and their subsequent realignment, replacement, and calibration." CNN reports: Some vehicles require "dynamic calibration," which means, once the sensors and cameras are back in place, a driver needs to take the vehicle out on real roads for testing. With proper equipment attached the car can, essentially, recalibrate itself as it watches lane lines and other markers. It requires the car to be driven for a set distance at a certain speed but weather and traffic can create problems. "If you're in Chicago or L.A., good luck getting to that speed," said [Hami Ebrahimi, chief commercial officer at Caliber] "or if you're in Seattle or Chicago or New York, with snow, good luck picking up all the road markings."

More commonly, vehicles need "static calibration," which can be done using machinery inside a closed workshop with a flat, level floor. Special targets are set up around the vehicle at set distances according to instructions from the vehicle manufacturer. "The car [views] those targets at those specific distances to recalibrate the world into the car's computer," Ebrahimi said. These kinds of repairs also demand buildings with open space that meet requirements including specific colors and lighting. And it requires special training for employees to perform these sorts of recalibrations, he said

"The change that we've seen in the last five years is greater than we've seen, probably, in the last five decades," said Todd Dillender, chief operating officer of Caliber Collision, one of the biggest auto body repair companies in the United States with more than 1,700 locations across 41 states. [...] With a rapidly changing industry, qualified auto body repair technicians are in short supply, just as they are in the engine repair business. That's also led to upward pressure on pay in the industry as technicians have to be highly qualified and educated, Dillender said. That's good for people who work in the industry, of course, but tougher for those who pay, and for the insurance companies who, in turn, pay for the repairs. A new study from consumer automotive group AAA says the cost to fix sensors and cameras in new vehicles "now accounts for more than a third of the post-crash repair costs," reports CNN. However, "no one, including AAA, recommends not getting these features because of repair costs," since many of them can cut crash rates in half and improve a car's overall safety.

"They're not going to prevent everything," said Greg Brannon, director of automotive engineering at AAA. "And when you are in a crash, there are additional costs so it's sort of the old 'there's no free ride' when it comes to these things."

Financial Times Alphaville: Look, we know we write a lot about Jane Street, but it's a fascinating place, and people seem interested in it. So it was hard to resist writing about the trading shop entering the mobile phone game space (kinda). Back in 2013 Jane Street developed a card game called "Figgie," which it made to simulate open outcry trading, teach trading nous, and generally burnish its reputation for quirkiness -- de rigueur in the industry.

All you need are 40 cards from a normal deck, and the rules have been public for a while. During Covid, Jane Street made a virtual version for remote interns. Now it's a mobile game that's publicly available on the official Apple and Google app stores.

"Out of an abundance of caution," Boeing says its historic Starliner launch has been postponed, citing an issue with the oxygen relief valve on the Atlas V rocket's upper stage. It was expected to launch tonight at 10:34 p.m. ET. TechCrunch reports: There are backup launch opportunities on May 7, 10 and 11. After years of delays and over $1 billion in cost overruns, the mission is set to be Boeing's first attempt to transport astronauts to the International Space Station. Once the issue is resolved with the upper stage, the United Launch Alliance Atlas V will carry the CST-100 Starliner capsule to orbit along with the two onboard astronauts -- Butch Wilmore and Sunny Williams -- from Florida's Cape Canaveral at 10:34 PM local time Monday evening. The mission also marks the first time ULA's Atlas will carry crew. The rocket boasts a success rate of 100% across 99 missions. (ULA is a joint venture of Boeing and Lockheed Martin.)

The astronauts would now dock at the station at the earliest on Thursday, where they would remain for at least eight days. The two astronauts will return to Earth in the capsule no earlier than May 16. If all goes to plan, Boeing will be able to finally certify its Starliner for human transportation and begin fulfilling the terms of its $4.2 billion NASA astronaut taxi contract. That contract, under the agency's Commercial Crew Program, was awarded in 2014. Elon Musk's SpaceX was also granted a contract under that program, for its Crew Dragon capsule, and has been transporting astronauts to and from the ISS since 2020.

An anonymous reader quotes a report from TechCrunch: CoreWeave, the GPU infrastructure provider that began life as a cryptocurrency mining operation, this week raised $1.1 billion in new funding from investors, including Coatue, Fidelity and Altimeter Capital. The round brings its valuation to $19 billion post-money and its total raised to $5 billion in debt and equity -- a remarkable figure for a company that's less than 10 years old. It's not just CoreWeave. Lambda Labs, which also offers an array of cloud-hosted GPU instances, in early April secured a "special purpose financing vehicle" of up to $500 million, months after closing a $320 million Series C round. The nonprofit Voltage Park, backed by crypto billionaire Jed McCaleb, last October announced that it's investing $500 million in GPU-backed data centers. And Together AI, a cloud GPU host that also conducts generative AI research, in March landed $106 million in a Salesforce-led round.

So why all the enthusiasm for -- and cash pouring into -- the alternative cloud space? The answer, as you might expect, is generative AI. As the generative AI boom times continue, so does the demand for the hardware to run and train generative AI models at scale. GPUs, architecturally, are the logical choice for training, fine-tuning and running models because they contain thousands of cores that can work in parallel to perform the linear algebra equations that make up generative models. But installing GPUs is expensive. So most devs and organizations turn to the cloud instead. Incumbents in the cloud computing space -- Amazon Web Services (AWS), Google Cloud and Microsoft Azure -- offer no shortage of GPU and specialty hardware instances optimized for generative AI workloads. But for at least some models and projects, alternative clouds can end up being cheaper -- and delivering better availability.

On CoreWeave, renting an Nvidia A100 40GB -- one popular choice for model training and inferencing -- costs $2.39 per hour, which works out to $1,200 per month. On Azure, the same GPU costs $3.40 per hour, or $2,482 per month; on Google Cloud, it's $3.67 per hour, or $2,682 per month. Given generative AI workloads are usually performed on clusters of GPUs, the cost deltas quickly grow. "Companies like CoreWeave participate in a market we call specialty 'GPU as a service' cloud providers," Sid Nag, VP of cloud services and technologies at Gartner, told TechCrunch. "Given the high demand for GPUs, they offers an alternate to the hyperscalers, where they've taken Nvidia GPUs and provided another route to market and access to those GPUs." Nag points out that even some Big Tech firms have begun to lean on alternative cloud providers as they run up against compute capacity challenges. Microsoft signed a multi-billion-dollar deal with CoreWeave last June to help provide enough power to train OpenAI's generative AI models.

"Nvidia, the furnisher of the bulk of CoreWeave's chips, sees this as a desirable trend, perhaps for leverage reasons; it's said to have given some alternative cloud providers preferential access to its GPUs," reports TechCrunch.

"Without San Francisco, Star Wars wouldn't exist," says David Reat, the culture studies director of the architecture department at Glasgow's University of Strathclyde.

SFGate reports: Lucas was born and raised in Modesto, where his father expected him to run the family stationery store once he turned 18, but Lucas instead left for Los Angeles, where he studied film production at the University of Southern California, before moving to San Francisco. Despite all that these cities had to offer, Lucas constantly found himself conflicted over his feelings toward them. "The battle of living in the country versus living in the city is huge with Lucas," says Reat, who notes that this theme runs throughout the likes of "THX 1138," "American Graffiti" and the "Star Wars" series. "He sees cities as the givers and takers of things. He's fascinated by cities. He doesn't actually want to live in one. He now lives in a ranch near one. He wants to orbit them. He's a paradox."

When Lucas moved to San Francisco in the late 1960s, there were a number of huge building projects taking place across the city that piqued the burgeoning filmmaker's interest, most notably the construction of BART and a new terminal at San Francisco airport. "Infrastructure really fascinated Lucas. They were these big huge alienating spaces," says Reat. "I think Lucas was driving around San Francisco, looking at them, and seeing that they looked alien." There's a reason why Lucas was particularly interested in the architecture in San Francisco: "He's on record as saying he wanted to be an architect," says Reat. "He has referred to himself as a frustrated architect." Lucas' interest provoked him and his creative team to put extra care and thought into each of the "Star Wars" buildings, vehicles, houses, villages, cities, worlds and galaxies, especially when it came to what they symbolized and represented.

"The architecture in the films play a key role for younger viewers," says Reat, explaining that it helps to indicate who is good and who is evil. When it comes to the Death Star there are "no women, no plants, no signs of life, and it's basically the Nazis in space," continues Reat. "Lucas doesn't like modernism. He always uses it for bad things, a bit like every James Bond baddie." Meanwhile, Luke Skywalker and the rest of the light side of the Force are seen living in "exaggerated domesticity" as they sit around drinking blue milk, surrounded by creatures. "There's a care and a weirdness to their architecture, plus it's loaded with color," says Reat, who adds that these choices help to make those characters more appealing and relatable....

The San Francisco International Airport also played a key role in the making of "Phantom Menace." A tour of its maintenance bay gave the film's creative designers a jolt of inspiration when they were creating Anakin's podracer and other vehicles.
The article also adds that the inspiration for the Theed Royal Palace on Naboo in The Phantom Menace was "the Marin County Civic Center, where Lucas once served jury duty."

An anonymous reader shared this report from SFGate: Late last year, tales of tech workers paying $700 a month for tiny "bed pods" in downtown San Francisco went viral. The story provided a perfect distillation of SF's wild (and wildly expensive) housing market — and inspired schadenfreude when the city deemed the situation illegal. But the provocative living situation wasn't an anomaly, according to a city official.

"We've definitely seen an uptick of these 'pod'-type complaints," Kelly Wong, a planner with San Francisco's code enforcement and zoning and compliance team, told SFGATE... Wong stressed that it's not that San Francisco is inherently against bed pod-type arrangements, but that the city is responsible for making sure these spaces are safe and legally zoned.

So Brownstone Shared Housing is still renting one bed pod location — but not accepting new tenants — after citations for failing to get proper permits and having a lock on the front door that required a key to exit.

And SFGate also spoke to Alex Akel, general manager of Olive Rooms, which opened up a co-living and co-working space in SoMa earlier this year (and also faced "a flurry of complaints.") "Unfortunately, we had complaints from neighbors because of foot traffic and noise, and since then we cut the number of people to fit the ordinance by the city," Akel wrote. Olive Rooms describes its space as targeted at "tech founders from Central Asia, giving them opportunities to get involved in the current AI boom." Akel added that its residents are "bringing new energy to SF," but that the program "will not accept new residents before we clarify the status with the city."

In April, the city also received a complaint about a group called Let's Be Buds, which rents out 14 pods in a loft on Divisadero Street that start at $575 per month for an upper bunk.

While this recent burst of complaints is new, bed pods in San Francisco have been catching flak for years... a company called PodShare, which rents — you guessed it — bed pods, squared itself away with the city and has operated in SF since 2019.
Brownstone's CEO told SFGate "A lot of people want to be here for AI, or for school, or different opportunities." He argues that "it's literally impossible without a product like ours," and that their residents had said the option "positively changed the trajectory of their lives."

An anonymous reader shared this report from the New York Times: American officials are trying to increase international pressure on Russia not to deploy an antisatellite nuclear weapon in space, and have obtained information that undermines Moscow's explanation that the device it is developing is for peaceful scientific purposes, a senior State Department official said on Friday...

On Friday, Mallory Stewart, the assistant secretary of state for arms control, said that while the United States had been aware of Russia's pursuit of such a device for years, "only recently have we been able to make a more precise assessment of their progress." Ms. Stewart, speaking at the nonpartisan Center for Strategic and International Studies in Washington, said the orbit the Russian satellite would occupy is in a high-radiation region not used by other satellites, information that undercuts Russia's defense that it is not developing a weapon.

An anonymous reader shared this report from the Washington Post: The heat shield of the Orion spacecraft intended one day to carry astronauts to the moon under NASA's Artemis program suffered unexpected damage in more than 100 places as the spacecraft returned to Earth during an uncrewed test flight in 2022, according to a watchdog report released late Wednesday.

While the capsule withstood the fiery tumult of reentry, when temperatures reached 5,000 degrees Fahrenheit as it plunged through the atmosphere at nearly 25,000 mph, the damage the heat shield suffered was far greater than NASA engineers had expected and more severe than NASA had revealed previously. Photos of the heat shield in the report showed gouges that look like small potholes. "Should the same issue occur on future Artemis missions, it could lead to the loss of the vehicle or crew," the report, by NASA's inspector general, concluded... The IG report provides the most detailed description of the issue to date. It also highlighted other problems with the spacecraft that could create significant challenges for the space agency as it seeks to return humans to the lunar surface for the first time in more than 50 years.

Portions of the heat shield "wore away differently than NASA engineers predicted, cracking and breaking off the spacecraft in fragments that created a trail of debris rather than melting away as designed," according to the report. That, in turn, "could have caused enough structural damage to cause one of Orion's parachutes to fail...." In addition to the heat shield erosion on Orion, which is manufactured by Lockheed Martin, the IG said several bolts on the crew module "experienced an exposed gap that allowed for increased heating to the bolt interior and greater than expected melting and erosion."
Earlier this year, NASA announced the next flight for its moon program — sending a crew of four around the moon — would be delayed, according to the article. The moon-orbiting mission would now occur "no earlier than September 2025, largely because officials wanted to study the heat shield issue further and understand why it eroded as it did."

The article adds that this new report "casts doubt on both NASA's rosy original assessment of the test flight" — as well as the likelihood that a lunar landing will occur by late 2026.

The Washington Post reports that wind turbines "only take up five percent of the land where they've been built, new research shows." The rest of the space can be used for other purposes, such as agriculture, according to a study published recently in the peer-reviewed journal Environmental Science and Technology. This means developers could fit turbines in places that are often perceived as unsuitable for a wind farm.

The new study highlights that turbines and existing human development, such as agriculture, cannot only share the same area, but also that building wind farms where there are already roads and other infrastructure could help reduce impacts on the land. "Clever siting, use of existing infrastructure, multiple use of landscapes — all these things ... can really contribute to solutions in areas where wind power is acceptable to the local people," said Sarah Jordaan, the study's principal investigator.

Historically, planning studies for wind farms have often assumed that turbines would disturb all the land at the site and leave the area unusable for anything else, said Jordaan, an associate professor in the department of civil engineering at McGill University. The study's findings provide a more accurate accounting of how much land is needed for wind farms, she added.

The world's highest astronomical site is officially open for business after being in the works for 26 years. Space.com reports: The Japanese University of Tokyo Atacama Observatory, or TAO, which was first conceptualized 26 years ago to study the evolution of galaxies and exoplanets, is perched on top of a tall mountain in the Chilean Andes at 5,640 meters (18,500 feet) above sea level. The facility's altitude surpasses even the Atacama Large Millimeter Array, which is at an elevation of 5,050 meters (16,570 feet).

TAO is located on the summit of Atacama's Cerro Chajnantor mountain, whose name means "place of departure" in the now-extinct Kunza language of the indigenous Likan Antai community. The region's high altitude, sparse atmosphere and perennially arid climate is deadly to humans, but makes an excellent spot for infrared telescopes like TAO as their observational accuracies rely on low moisture levels, which render Earth's atmosphere transparent in infrared wavelengths.

TAO's 6.5-meter telescope consists of two science instruments designed to observe the universe in infrared, which is electromagnetic radiation with a wavelength longer than visible light but shorter than microwaves. One of the instruments, named SWIMS, will image galaxies from the very early universe to understand how they coalesced out of pristine dust and gas, a process whose specifics remain murky despite decades of research. The second, named MIMIZUKU, will aid the overarching science goal by studying primordial disks of dust within which stars and galaxies are known to form, according to the mission plan. Constructing the telescope on the summit of Mt. Chajnantor "was an incredible challenge, not just technically, but politically too," Yuzuru Yoshii, a professor at the University of Tokyo in Japan who spearheaded TAO since 1998, said in a statement. "I have liaised with Indigenous peoples to ensure their rights and views are considered, the Chilean government to secure permission, local universities for technical collaboration, and even the Chilean Health Ministry to make sure people can work at that altitude in a safe manner."

"Thanks to all involved, research I've only ever dreamed about can soon become a reality, and I couldn't be happier," he added.

An anonymous reader quotes a report from The Guardian: Oil and gas equipment intended to cut methane emissions is preventing scientists from accurately detecting greenhouse gases and pollutants, a satellite image investigation has revealed. Energy companies operating in countries such as the US, UK, Germany and Norway appear to have installed technology that could stop researchers from identifying methane, carbon dioxide emissions and pollutants at industrial facilities involved in the disposal of unprofitable natural gas, known in the industry as flaring. Flares are used by fossil fuel companies when capturing the natural gas would cost more than they can make by selling it. They release carbon dioxide and toxic pollutants when they burn as well as cancer-causing chemicals. Despite the health risks, regulators sometimes prefer flaring to releasing natural gas -- which is 90% methane -- directly into the atmosphere, known as "venting".

The World Bank, alongside the EU and other regulators, have been using satellites for years to find and document gas flares, asking energy companies to find ways of capturing the gas instead of burning or venting it. The bank set up the Zero Routine Flaring 2030 initiative at the Paris climate conference to eradicate unnecessary flaring, and its latest report stated that flaring decreased by 3% globally from 2021 to 2022. But since the initiative, "enclosed combustors" have begun appearing in the same countries that promised to end flaring. Experts say enclosed combustors are functionally the same as flares, except the flame is hidden. Tim Doty, a former regulator at the Texas Commission on Environmental Quality, said: "Enclosed combustors are basically a flare with an internal flare tip that you don't see. Enclosed flaring is still flaring. It's just different infrastructure that they're allowing.

"Enclosed flaring is, in truth, probably less efficient than a typical flare. It's better than venting, but going from a flare to an enclosed flare or a vapor combustor is not an improvement in reducing emissions." The only method of detecting flaring globally is by using satellite-mounted tools called Visible Infrared Imaging Radiometer Suite of detectors (VIIRS), which find flares by comparing heat signatures with bright spots of light visible from space. But when researchers tried to replicate the database, they saw that the satellites were not picking up the enclosed flares. Without the satellite data, countries were forced to rely mostly on self-disclosed reporting from oil and gas companies, researchers said. Environmentalists fear the research community's ability to understand pollution and greenhouse gas emissions from the energy sector could be jeopardized.

Florida Gov. Ron DeSantis signed a bill this week banning and criminalizing the manufacture and sale of lab-grown meat in the state. From a report: The legislation joins similar efforts from three other states -- Alabama, Arizona and Tennessee -- that have also looked to stop the sale of lab-grown meat, which is believed to still be years away from commercial viability. "Florida is fighting back against the global elite's plan to force the world to eat meat grown in a petri dish or bugs to achieve their authoritarian goals," DeSantis said. "We will save our beef."

Lab-grown meat, also known as cultivated meat, has attracted considerable attention in recent years as startups have raised millions of dollars to improve the technology meant to create a climate-friendly alternative to traditional meat sources. Cultivated meat is usually grown in a metal vessel from a sample of animal cells. They multiply in a container called a bioreactor while being fed with water, amino acids, vitamins and lipids -- a process that can be difficult to do at scales large enough to create enough food for commercial sale. Still, some companies have made strides, with two California startups receiving approval from U.S. regulators last year to sell lab-grown chicken. Those companies said Florida's bill stifles innovation in a space that is becoming competitive globally.

China launched an uncrewed lunar mission Friday that aims to bring back samples from the far side of the moon for the first time, in a potentially major step forward for the country's ambitious space program. From a report: The Chang'e-6 probe -- China's most complex robotic lunar mission to date -- blasted off on a Long March-5 rocket from the Wenchang Space Launch Center in south China's Hainan island, where space fans had gathered to watch the historic moment. The country's National Space Administration said the launch was a success. The launch marks the start of a mission that aims to be a key milestone in China's push to become a dominant space power with plans to land astronauts on the moon by 2030 and build a research base on its south pole.

It comes as a growing number of countries, including the United States, eye the strategic and scientific benefits of expanded lunar exploration in an increasingly competitive field. China's planned 53-day mission would see the Chang'e-6 lander touch down in a gaping crater on the moon's far side, which never faces Earth. China became the first and only country to land on the moon's far side during its 2019 Chang'e-4 mission. Any far-side samples retrieved by the Chang'e-6 lander could help scientists peer back into the evolution of the moon and the solar system itself -- and provide important data to advance China's lunar ambitions.
