Hubble Spots Water Vapor in Small Exoplanet's Atmosphere (scitechdaily.com) 28

"Astronomers using NASA's Hubble Space Telescope observed the smallest exoplanet where water vapor has been detected in the atmosphere," writes SciTechDaily.

"At only approximately twice Earth's diameter, the planet GJ 9827d could be an example of potential planets with water-rich atmospheres elsewhere in our galaxy." "This would be the first time that we can directly show through an atmospheric detection, that these planets with water-rich atmospheres can actually exist around other stars," said team member Björn Benneke of the Trottier Institute for Research on Exoplanets at Université de Montréal. "This is an important step toward determining the prevalence and diversity of atmospheres on rocky planets."

"Water on a planet this small is a landmark discovery," added co-principal investigator Laura Kreidberg of Max Planck Institute for Astronomy in Heidelberg, Germany. "It pushes closer than ever to characterizing truly Earth-like worlds."

However, it remains too early to tell whether Hubble spectroscopically measured a small amount of water vapor in a puffy hydrogen-rich atmosphere, or if the planet's atmosphere is mostly made of water, left behind after a primeval hydrogen/helium atmosphere evaporated under stellar radiation... Because the planet is as hot as Venus, at 800 degrees Fahrenheit, it definitely would be an inhospitable, steamy world if the atmosphere were predominantly water vapor...

"Observing water is a gateway to finding other things," said Thomas Greene, astrophysicist at NASA's Ames Research Center in California's Silicon Valley. "This Hubble discovery opens the door to future study of these types of planets by the James Webb Space Telescope.

'Massive Amounts' of Carbon Sequestered for Centuries Released By Clearing Indonesia's Peatland (msn.com) 130

"Indonesia has been clearing tens of thousands of acres of densely vegetated peatland for farming, releasing massive amounts of carbon that had been sequestered below for centuries," reports the Washington Post, "and destroying one of the Earth's most effective means of storing greenhouse gases." The country is home to as much as half of the planet's tropical peatland, a unique ecosystem that scientists say is vital to averting the worst results of climate change. Government leaders have made halting efforts to protect peatlands over the last two decades, but three years ago, when the pandemic disrupted food supply chains, officials launched an ambitious land-clearance operation in a push to expand the cultivation of crops and cut Indonesia's reliance on expensive imports. By transforming 2,000 to 4,000 square miles of what environmental groups say is predominantly peatland into fields of rice, corn and cassava, the government projects that it will achieve self-sufficiency in food... But disrupting the peatlands comes with devastating, likely irreversible costs for the climate, say environmental experts and activists.

"To restore these vast areas of peat forest being destroyed will take years and huge investments in labor and funds," said David Taylor, a professor of tropical environmental change at the National University of Singapore who has researched peatlands in Asia and Africa. To do it on the timeline that global leaders have set for the world to achieve net-zero emissions? "Near impossible," Taylor said... While peatlands make up just 3 percent of the Earth's land, they store twice as much carbon as all the world's forests combined, according to the United Nations. When peatlands are drained, layers of aged biomass that are exposed to oxygen-rich air decay at an accelerated rate, releasing carbon from bygone eras into the atmosphere.

Even worse, when the weather turns hot, unprotected peat dries out, becoming combustible. Already, environmental activists and villagers in Kalimantan, the Indonesian portion of the island of Borneo, say peatlands cleared by the government are fueling more-intense wildfires... Left intact, peatlands are naturally protected against fire. Once degraded, however, they produce infernos that are notoriously difficult to put out because they can travel underground, feeding on dried biomass yards below the surface.

Tropical peatlands are also threatened by development in Peru and Africa's Congo Basin, according to the article. But they add that there's something especially ironic about Indonesia's government project. "Research shows that tropical peatlands tend to be too acidic to grow crops.

"Indonesian environmental groups, including Pantau Gambut and WALHI, said they have documented widespread crop failures in areas targeted by the government's project. Rice planted in some peat-rich areas has had less than a third of the yield of rice planted in mineral soil, according to the groups' analysis."

Photo Shows Japan's Moon Lander Arrived Upside-Down (mashable.com) 22

"A photo of Japan's robotic moon lander shows that though the spacecraft did make the quarter-million-mile journey to the lunar surface, it landed upside down..." reports Mashable. Because of the lander's now-apparent inverted position, its solar panels weren't oriented correctly to generate power, according to the space agency. The team elected to conserve power by shutting down the spacecraft about 2.5 hours after landing.

What's perhaps as surprising as the photo of the lander is how it was taken. Two small rovers separated from the crewless mothership just prior to touchdown. It was one of these baseball-sized robots that was able to snap the image of the spacecraft with its head in the moondust. The rover, built with the help of Japanese toy maker Takara Tomy, is a sphere that splits in half to expose a pair of cameras that point front and back. The two hemispheres also become the rover wheels. "The company is perhaps most famous for originally creating the Transformers, the alien robots that can disguise themselves as machines," said Elizabeth Tasker, who provided commentary on the moon landing in English on Jan. 20.

The space agency still isn't entirely sure what went wrong. At about 55 yards above the ground, the spacecraft performed an obstacle avoidance maneuver, part of the pinpoint-landing demonstration. Just prior to this step, one of the two main engines stopped thrusting, throwing the lander's orientation off. JAXA is continuing to investigate what caused the engine problem... Despite the fact that the spacecraft is now sleeping, the SLIM team hasn't lost hope for a recovery. With solar panels facing west, the lander still has a chance of catching some rays and generating power. If the angle of sunlight changes, SLIM could still be awakened, mission officials said.

That would have to happen soon, though. Night will fall on the moon on Feb. 1, bringing about freezing temperatures. The spacecraft was not built to withstand those conditions.

NASA's Lunar Reconnaissance Orbiter spacecraft has now passed over the landing site at an altitude of about 50 miles (80 km) — and snapped their own photograph which they say shows "the slight change in reflectance around the lander due to engine exhaust sweeping the surface."

Did a Lake on Mars Once Contain Life? (upi.com) 17

UPI reports: New research published Friday offers hope that the sediment samples picked up by the Mars rover Perseverance could reveal traces of life — if it ever existed on the Red Planet.

The rover already has confirmed an ancient lake on Mars. The new research published in Science Advances shows the Jezero Crater, where Perseverance verified lake sediments, is theorized to have been filled with water that deposited layers of sediments on the crater floor. "The delta deposits in Jezero Crater contain sedimentary records of potentially habitable conditions on Mars," the research article's abstract stated. "NASA's Perseverance rover is exploring the Jezero western delta with a suite of instruments that include the RIMFAX ground penetrating radar, which provides continuous subsurface images that probe up to 20 meters below the rover."

The research by UCLA and the University of Oslo shows the lake subsequently shrank and the sediments carried by a river formed a large delta... [R]adar images revealed sediments shaped like lake deposits on Earth. Their existence was confirmed by the new research.

Climate Change Cripples Panama Canal. Fixing it Could Take Years (yahoo.com) 148

"Parched conditions have crippled a waterway that handles $270 billion a year in global trade," reports Bloomberg. "And there are no easy solutions.

"The Panama Canal Authority is weighing potential fixes that include an artificial lake to pump water into the canal and cloud seeding to boost rainfall, but both options would take years to implement, if they're even feasible. " With water levels languishing at six feet (1.8 meters) below normal, the canal authority capped the number of vessels that can cross. The limits imposed late last year were the strictest since 1989... Some shippers are paying millions of dollars to jump the growing queue, while others are taking longer, costlier routes around Africa or South America. The constraints have since eased slightly due to a rainier-than-expected November, but at 24 ships a day, the maximum is still well below the pre-drought daily capacity of about 38. As the dry season takes hold, the bottleneck is poised to worsen again...

The canal's travails reflect how climate change is altering global trade flows. Drought created chokepoints last year on the Mississippi River in the US and the Rhine in Europe. In the UK, rising sea levels are elevating the risk of flooding along the Thames. Melting ice is creating new shipping routes in the Arctic. Under normal circumstances, the Panama Canal handles about 3% of global maritime trade volumes and 46% of containers moving from Northeast Asia to the US East Coast...

In the long term, the primary solution to chronic water shortages will be to dam up the Indio River and then drill a tunnel through a mountain to pipe fresh water 8 kilometers (5 miles) into Lake Gatún, the canal's main reservoir. The project, along with additional conservation measures, will cost about $2 billion, Erick Córdoba, the manager of the water division at the canal authority estimates. He says it will take at least six years to dam up and fill the site. The US Army Corps of Engineers is conducting a feasibility study. The Indio River reservoir would increase vessel traffic by 11 to 15 a day, enough to keep Panama's top moneymaker working at capacity while guaranteeing fresh water for Panama City...

The country will need to dam even more rivers to guarantee water through the end of the century.

NASA Finally Unlocks Canister of Dust From 4.6 Billion-Year-Old Asteroid (theguardian.com) 47

NASA announced Friday that it finally got a canister of asteroid dust open, four months after it parachuted down through the Earth's atmosphere into the Utah desert. The Guardian reports: The space administration announced Friday that it had successfully removed two stuck fasteners that had prevented some of the samples collected in 2020 from the 4.6bn-year-old asteroid Bennu, which is classified as a "potentially hazardous" because it has one in 1,750 chance of crashing into Earth by 2300. Most of the rock samples collected by Nasa's Osiris-Rex mission were retrieved soon after the canister landed in September, but additional material remaining inside a sampler head that proved difficult to access.

After months of wrestling with the last two of 35 fasteners, scientists in Houston managed to get them dislodged. "It's open! It's open!" Nasa's planetary science division posted on Twitter/X. The division also posted a photograph of dust and small rocks inside the canister. According to the Los Angeles Times, the team designed custom tools made from a specific grade of surgical, non-magnetic stainless steel to pry it open -- all without the samples being contaminated by Earthly air. Nasa said it will now analyze the nine-ounce sample.

Exxon Takes Activists To Court Over Emissions Proposal (techcrunch.com) 77

Exxon Mobil has filed a complaint in a Texas court seeking to block a climate proposal by activist investors from a shareholder vote in May. This marks Exxon's first legal action against such a proposal. Exxon argues the proposal, which urges adoption of emissions targets for Exxon's products, does not serve shareholder interests. The activist investors counter that Exxon is the only major oil company lacking these targets. TechCrunch: The problem Exxon faces is that the "basic rules of society," specifically "those embedded in ethical custom," are changing, and the company now finds itself on the wrong side of them. Two-thirds of Americans say we should prioritize alternative energy over fossil fuels, and 69% say the U.S. should move toward net-zero emissions by 2050, according to the Pew Research Center. Internationally, most people want their governments to do something about climate change.

Exxon would normally take its grievances to the SEC, filing a request with the regulator to omit the proposal from this year's proxy statement. But under the Biden administration, the SEC has been siding more frequently with shareholders. After all, who's the boss?

NASA Regains Contact With Its 'Ingenuity' Mars Helicopter (npr.org) 12

"Good news..." NASA posted Saturday night on X. "We've reestablished contact with the Mars Helicopter..."

After a two-day communications blackout, NASA had instructed its Perseverance Mars rover "to perform long-duration listening sessions for Ingenuity's signal" — and apparently they did the trick. "The team is reviewing the new data to better understand the unexpected comms dropout" during the helicopter's record-breaking 72nd flight.

Slashdot reader Thelasko shared this report from NPR: Communications broke down on Thursday, when the little autonomous rotorcraft was sent on a "quick pop-up vertical flight," to test its systems after an unplanned early landing during its previous flight, the agency said in a status update on Friday night. The Perseverance rover, which relays data between the helicopter and Earth during the flights, showed that Ingenuity climbed to its assigned maximum altitude of 40 feet, NASA said.

During its planned descent, the helicopter and rover stopped communicating with each other...

Even before it came back online, RockDoctor (Slashdot reader #15,477) pointed out that the Mars copter has done this before. "Batteries dieing, resulting in a communications re-set, If I remember correctly."

Space.com also noted additional alternatives: "Perseverance is currently out of line-of-sight with Ingenuity, but the team could consider driving closer for a visual inspection," NASA's Jet Propulsion Laboratory in Southern California, which manages both robots' missions, said via X on Friday.

Ingenuity has stayed aloft for more than 128 minutes and covered a total of 11 miles (17.7 kilometers) during its 72 Mars flights, according to the mission's flight log.

Ultra-Large Structure Discovered In Distant Space Challenges Cosmological Principle (scitechdaily.com) 60

"The discovery of a second ultra-large structure in the remote universe has further challenged some of the basic assumptions about cosmology," writes SciTechDaily: The Big Ring on the Sky is 9.2 billion light-years from Earth. It has a diameter of about 1.3 billion light-years, and a circumference of about four billion light-years. If we could step outside and see it directly, the diameter of the Big Ring would need about 15 full Moons to cover it.

It is the second ultra-large structure discovered by University of Central Lancashire (UCLan) PhD student Alexia Lopez who, two years ago, also discovered the Giant Arc on the Sky. Remarkably, the Big Ring and the Giant Arc, which is 3.3 billion light-years across, are in the same cosmological neighborhood — they are seen at the same distance, at the same cosmic time, and are only 12 degrees apart on the sky. Alexia said: "Neither of these two ultra-large structures is easy to explain in our current understanding of the universe. And their ultra-large sizes, distinctive shapes, and cosmological proximity must surely be telling us something important — but what exactly?

"One possibility is that the Big Ring could be related to Baryonic Acoustic Oscillations (BAOs). BAOs arise from oscillations in the early universe and today should appear, statistically at least, as spherical shells in the arrangement of galaxies. However, detailed analysis of the Big Ring revealed it is not really compatible with the BAO explanation: the Big Ring is too large and is not spherical." Other explanations might be needed, explanations that depart from what is generally considered to be the standard understanding in cosmology...

And if the Big Ring and the Giant Arc together form a still larger structure then the challenge to the Cosmological Principle becomes even more compelling... Alexia said, "From current cosmological theories we didn't think structures on this scale were possible. "

Possible explanations include a Conformal Cyclic Cosmology, or the effect of cosmic strings passing through...

'For Truckers Driving EVs, There's No Going Back' (yahoo.com) 153

The Washington Post looks at "a small but growing group of commercial medium-to-heavy-duty truck drivers who use electric trucks."

"These drivers — many of whom operate local or regional routes that don't require hundreds of miles on the road in a day — generally welcome the transition to electric, praising their new trucks' handling, acceleration, smoothness and quiet operation. "Everyone who has had an EV has no aspirations to go back to diesel at this point," said Khari Burton, who drives an electric Volvo VNR in the Los Angeles area for transport company IMC. "We talk about it and it's all positivity. I really enjoy the smoothness ... and just the quietness as well." Mike Roeth, the executive director of the North American Council for Freight Efficiency, said many drivers have reported that the new vehicles are easier on their bodies — thanks to both less rocking off the cab, assisted steering and the quiet motor. "Part of my hypothesis is that it will help truck driver retention," he said. "We're seeing people who would retire driving a diesel truck now working more years with an electric truck."

Most of the electric trucks on the road today are doing local or regional routes, which are easier to manage with a truck that gets only up to 250 miles of range... Trucking advocates say electric has a long way to go before it can take on longer routes. "If you're running very local, very short mileage, there may be a vehicle that can do that type of route," said Mike Tunnell, the executive director of environmental affairs for the American Trucking Association. "But for the average haul of 400 miles, there's just nothing that's really practical today."

There's other concerns, according to the article. "[S]ome companies and trucking associations worry this shift, spurred in part by a California law mandating a switch to electric or emissions-free trucks by 2042, is happening too fast. While electric trucks might work well in some cases, they argue, the upfront costs of the vehicles and their charging infrastructure are often too heavy a lift."

But this is probably the key sentence in the article: For the United States to meet its climate goals, virtually all trucks must be zero-emissions by 2050. While trucks are only 4 percent of the vehicles on the road, they make up almost a quarter of the country's transportation emissions.
The article cites estimates that right now there's 12.2 million trucks on America's highways — and barely more than 1% (13,000) are electric. "Around 10,000 of those trucks were just put on the road in 2023, up from 2,000 the year before." (And they add that Amazon alone has thousands of Rivian's electric delivery vans, operating in 1,800 cities.)

But the article's overall message seems to be that when it comes to the trucks, "the drivers operating them say they love driving electric." And it includes comments from actual truckers:
  • 49-year-old Frito-Lay trucker Gary LaBush: "I was like, 'What's going on?' There was no noise — and no fumes... it's just night and day."
  • 66-year-old Marty Boots: Diesel was like a college wrestler. And the electric is like a ballet dancer... You get back into diesel and it's like, 'What's wrong with this thing?' Why is it making so much noise? Why is it so hard to steer?"

SpaceX's 'Dragon' Capsule Carries Four Private Astronauts to the ISS for Axiom Space (arstechnica.com) 35

"It's the third all-private astronaut mission to the International Space Station," writes NASA — and they're expected to start boarding within the next hour!

Watch it all on the official stream of NASA TV.

More details from Ars Technica: The four-man team lifted off from NASA's Kennedy Space Center in Florida aboard a SpaceX Falcon 9 rocket Thursday, kicking off a 36-hour pursuit of the orbiting research laboratory. Docking is scheduled for Saturday morning. This two-week mission is managed by Houston-based Axiom Space, which is conducting private astronaut missions to the ISS as a stepping stone toward building a fully commercial space station in low-Earth orbit by the end of this decade.

Axiom's third mission, called Ax-3, launched at 4:49 pm EST (21:49 UTC) Thursday. The four astronauts were strapped into their seats inside SpaceX's Dragon Freedom spacecraft atop the Falcon 9 rocket. This is the 12th time SpaceX has launched a human spaceflight mission, and could be the first of five Dragon crew missions this year.

NASA reports that the crew "will spend about two weeks conducting microgravity research, educational outreach, and commercial activities aboard the space station." NASA Administrator Bill Nelson said "During their time aboard the International Space Station, the Ax-3 astronauts will carry out more than 30 scientific experiments that will help advance research in low-Earth orbit. As the first all-European commercial astronaut mission to the space station, the Ax-3 crew is proof that the possibility of space unites us all...."

The Dragon spacecraft will dock autonomously to the forward port of the station's Harmony module as early as 4:19 a.m. [EST] Saturday. Hatches between Dragon and the station are expected to open after 6 a.m. [EST], allowing the Axiom crew to enter the complex for a welcoming ceremony and start their stay aboard the orbiting laboratory.... The Ax-3 astronauts are expected to depart the space station Saturday, February 3, pending weather, for a return to Earth and splashdown at a landing site off the coast of Florida.

Crime Rings Are Trafficking in an Unlikely Treasure: Sand 53

Organized crime is mining sand from rivers and coasts to feed demand worldwide, ruining ecosystems and communities. Can it be stopped? Scientific American reports: Very few people are looking closely at the illegal sand system or calling for changes, however, because sand is a mundane resource. Yet sand mining is the world's largest extraction industry because sand is a main ingredient in concrete, and the global construction industry has been soaring for decades. Every year the world uses up to 50 billion metric tons of sand, according to a United Nations Environment Program report. The only natural resource more widely consumed is water. A 2022 study by researchers at the University of Amsterdam concluded that we are dredging river sand at rates that far outstrip nature's ability to replace it, so much so that the world could run out of construction-grade sand by 2050. The U.N. report confirms that sand mining at current rates is unsustainable.

The greatest demand comes from China, which used more cement in three years (6.6 gigatons from 2011 through 2013) than the U.S. used in the entire 20th century (4.5 gigatons), notes Vince Beiser, author of The World in a Grain. Most sand gets used in the country where it is mined, but with some national supplies dwindling, imports reached $1.9 billion in 2018, according to Harvard's Atlas of Economic Complexity. Companies large and small dredge up sand from waterways and the ocean floor and transport it to wholesalers, construction firms and retailers. Even the legal sand trade is hard to track. Two experts estimate the global market at about $100 billion a year, yet the U.S. Geological Survey Mineral Commodity Summaries indicates the value could be as high as $785 billion.

Sand in riverbeds, lake beds and shorelines is the best for construction, but scarcity opens the market to less suitable sand from beaches and dunes, much of it scraped illegally and cheaply. With a shortage looming and prices rising, sand from Moroccan beaches and dunes is sold inside the country and is also shipped abroad, using organized crime's extensive transport networks, Abderrahmane has found. More than half of Morocco's sand is illegally mined, he says.

Cop28 Deal Will Fail Unless Rich Countries Quit Fossil Fuels, Says Climate Negotiator 184

The credibility of the Cop28 agreement to "transition away" from fossil fuels rides on the world's biggest historical polluters like the US, UK and Canada rethinking current plans to expand oil and gas production, according to the climate negotiator representing 135 developing countries. The Guardian: In an exclusive interview with the Guardian, Pedro Pedroso, the outgoing president of the G77 plus China bloc of developing countries, warned that the landmark deal made at last year's climate talks in Dubai risked failing. "We achieved some important outcomes at Cop28 but the challenge now is how we translate the deal into meaningful action for the people," Pedroso said. "As we speak, unless we lie to ourselves, none of the major developed countries, who are the most important historical emitters, have policies that are moving away from fossil fuels, on the contrary, they are expanding," said Pedroso.

These countries must also deliver adequate finance for poorer nations to transition -and adapt to the climate crisis. In Dubai, Sultan Al Jaber, Cop28 president and chief of the Emirates national oil company, was subject to widespread scrutiny -- understandable given that the UAE is the world's seventh biggest oil producer with the fifth largest gas reserves. Yet the US was by far the biggest oil and gas producer in the world last year -- setting a new record, during a year that was the hottest ever recorded. The US, UK, Canada, Australia and Norway account for 51% of the total planned oil and gas expansion by 2050, according to research by Oil Change International. "It's very easy to label some emerging economies, especially the Gulf states, as climate villains, but this is very unfair by countries with historic responsibilities -- who keep trying to scapegoat and deviate the attention away from themselves. Just look at US fossil fuel plans and the UK's new drilling licenses for the North Sea, and Canada which has never met any of its emission reduction goals, not once," said Pedroso, a Cuban diplomat.

Greenland's Ice Sheet Melting Faster Than Scientists Previously Estimated, Study Finds 86

Scientists have underestimated recent mass loss from Greenland by as much as 20%, finds a new study published in the journal Nature. CBS News reports: Since 1985, Greenland's ice sheet has lost approximately 5,091 square kilometers of ice researchers found using satellite imagery. Scientists said earlier estimates did not track melting at the edges of the ice sheets, known as calving, which measures ice breaking off at the terminus of a glacier. Greenland's ice sheet loses about 193 square kilometers of ice per year, researchers found. Study co-author Chad Greene and his colleagues said they qualified the extent of calving, which increased the scope of ice mass lost.

They combined "236,328 observations of glacier terminus positions" compiled from various public data sets to capture monthly ice melt. Their measurements found that between 1985 and 2022, almost every glacier in Greenland experienced some level of loss. [...] Researchers in the study noted that "this retreat does not appear to substantially contribute to sea level rise" because most of the glacier margins the scientists measured were already underwater. The loss, however, may play a part in ocean circulation patterns, and how heat energy is distributed across the planet.

US Must Beat China Back To the Moon, Congress Tells NASA (space.com) 114

With NASA's Artemis moon program now targeting September 2025 for its Artemis 2 mission and September 2026 for Artemis 3, some members of Congress are concerned about the potential repercussions, particularly with China's growing ambitions in lunar exploration. "For the United States and its partners not to be on the moon when others are on the moon is unacceptable," said Mike Griffin, former NASA administrator. "We need a program that is consistent with that theme. Artemis is not that program. We need to restart it, not keep it on track." Space.com reports: The U.S. House of Representatives' Committee on Science, Space and Technology held a hearing about the new Artemis plan today (Jan. 17), and multiple members voiced concern about the slippage. "I remind my colleagues that we are not the only country interested in sending humans to the moon," Committee Chairman Frank Lucas (R-OK) said in his opening remarks. "The Chinese Communist Party is actively soliciting international partners for a lunar mission -- a lunar research station -- and has stated its ambition to have human astronauts on the surface by 2030," he added. "The country that lands first will have the ability to set a precedent for whether future lunar activities are conducted with openness and transparency, or in a more restricted manner."

The committee's ranking member, California Democrat Zoe Lofgren (D-CA), voiced similar sentiments. "Let me be clear: I support Artemis," she said in her opening remarks. "But I want it to be successful, especially with China at our heels. And we want to be helpful here in the committee in ensuring that Artemis is strong and staying on track as we look to lead the world, hand-in-hand with our partners, in the human exploration of the moon and beyond." Several other committee members stressed that the new moon race is part of a broader competition with China, and that coming in second could imperil U.S. national security.

"It's no secret that China has a goal to surpass the United States by 2045 as global leaders in space. We can't allow this to happen," Rich McCormick (R-GA) said during the hearing. "I think the leading edge that we have in space technology will protect the United States -- not just the economy, but technologies that can benefit humankind." And Bill Posey (R-FL) referred to space as the "ultimate military high ground," saying that whoever leads in the final frontier "will control the destiny of this Earth."

Human 'Behavioral Crisis' At Root of Climate Breakdown, Say Scientists (theguardian.com) 300

In a new paper published in the journal Science Progress, author Joseph Merz argues that climate issues are symptoms of ecological overshoot, driven by exploited human behaviors such as overconsumption, waste, and population growth. The paper emphasizes the need to change societal norms and behaviors through various means, including using marketing and media strategies to promote sustainable living, rather than solely focusing on technological or policy solutions. The Guardian reports: Merz and colleagues believe that most climate "solutions" proposed so far only tackle symptoms rather than the root cause of the crisis. This, they say, leads to increasing levels of the three "levers" of overshoot: consumption, waste and population. They claim that unless demand for resources is reduced, many other innovations are just a sticking plaster. "We can deal with climate change and worsen overshoot," says Merz. "The material footprint of renewable energy is dangerously underdiscussed. These energy farms have to be rebuilt every few decades -- they're not going to solve the bigger problem unless we tackle demand."

"Overshoot" refers to how many Earths human society is using up to sustain -- or grow -- itself. Humanity would currently need 1.7 Earths to maintain consumption of resources at a level the planet's biocapacity can regenerate. Where discussion of climate often centers on carbon emissions, a focus on overshoot highlights the materials usage, waste output and growth of human society, all of which affect the Earth's biosphere. "Essentially, overshoot is a crisis of human behavior," says Merz. "For decades we've been telling people to change their behavior without saying: 'Change your behavior.' We've been saying 'be more green' or 'fly less', but meanwhile all of the things that drive behavior have been pushing the other way. All of these subtle cues and not so subtle cues have literally been pushing the opposite direction -- and we've been wondering why nothing's changing."

The paper explores how neuropsychology, social signaling and norms have been exploited to drive human behaviors which grow the economy, from consuming goods to having large families. The authors suggest that ancient drives to belong in a tribe or signal one's status or attract a mate have been co-opted by marketing strategies to create behaviors incompatible with a sustainable world. "People are the victims -- we have been exploited to the point we are in crisis. These tools are being used to drive us to extinction," says the evolutionary behavioral ecologist and study co-author Phoebe Barnard. "Why not use them to build a genuinely sustainable world?" Just one-quarter of the world population is responsible for nearly three-quarters of emissions. The authors suggest the best strategy to counter overshoot would be to use the tools of the marketing, media and entertainment industries in a campaign to redefine our material-intensive socially accepted norms.
"We're talking about replacing what people are trying to signal, what they're trying to say about themselves. Right now, our signals have a really high material footprint -- our clothes are linked to status and wealth, their materials sourced from all over the world, shipped to south-east Asia most often and then shipped here, only to be replaced by next season's trends. The things that humans can attach status to are so fluid, we could be replacing all of it with things that essentially have no material footprint -- or even better, have an ecologically positive one."

Apple Vision Pro Will Launch With 3D Movies From Disney Plus (theverge.com) 59

Apple has announced several new experiences launching with their upcoming Vision Pro spatial computing headset, including 3D content from Disney Plus. "Other apps announced with Vision Pro support include ESPN, MLB, PGA Tour, Max, Discovery Plus, Amazon Prime Video, Paramount Plus, Peacock, Pluto TV, Tubi, Fubo, Crunchyroll, Red Bull TV, IMAX, TikTok, and MUBI," reports The Verge, noting that Netflix's existing app "will work unmodified on Apple's new headset." From the report: The announcement lists some of the movies that will be in 3D, and naturally, Avatar: The Way of Water is among them. But Vision Pro owners will also get 3D versions of movies like Avengers: Endgame, Star Wars: The Force Awakens, and Encanto. The movies will be available to rent through the Apple TV app, and the company says that anyone who has already bought the movies will now get 3D versions without paying extra. Otherwise, "more titles, including those available exclusively to Disney Plus subscribers, will be announced at a later date."

Among the four screening environments for Disney Plus subscribers, one is called the Disney Plus Theater, which the company says takes inspiration from Hollywood's El Capitan Theatre, as well as others based on Pixar's Monsters, Inc., the fictional Avengers Tower from Marvel Avengers films, and one set in the cockpit of a landspeeder sitting in Star Wars' Tatooine desert. Besides Disney content, Apple mentioned the Apple TV app will have some free "immersive entertainment" that includes Alicia Keys: Rehearsal Room and a film from Planet Earth producers called Prehistoric Planet Immersive.
The $3,499 Vision Pro headset will start shipping on February 2nd. Pre-orders begin January 19th at 8AM ET.

Japan Startup Eyes Fusion Laser To Shoot Down Space Junk From Ground (nikkei.com) 48

Japanese startup EX-Fusion plans to eliminate small pieces of space junk with laser beams fired from the ground. Nikkei Asia reports: EX-Fusion stands apart in that it is taking the ground-based approach, with the startup tapping its arsenal of laser technology originally developed in pursuit of fusion power. In October, EX-Fusion signed a memorandum of understanding with EOS Space Systems, an Australian contractor that possesses technology used to detect space debris. EX-Fusion plans to place a high-powered laser inside an observatory operated by EOS Space outside of Canberra. The first phase will be to set up laser technology to track debris measuring less than 10 cm. Pieces of this size have typically been difficult to target from the ground using lasers.

For the second phase, EX-Fusion and EOS Space will attempt to remove the space debris by boosting the power of the laser beams fired from the surface. The idea is to fire the laser intermittently against the debris from the opposing direction of its travel in order to slow it down. With a decreased orbiting speed, the debris will enter the Earth's atmosphere to burn up. High-powered lasers are often associated with weapons that blast objects into smithereens. Indeed, the EOS Space group supplies laser weapon systems used to destroy drones. But lasers designed to remove space debris are completely different from weapon-grade lasers, EOS Space's executive vice president James Bennett said during a visit to Japan in November.

Current laser weaponry often uses fiber lasers, which are capable of cutting and welding metal and can destroy targets like drones through heat created from continuous firing. Capturing and removing space junk instead involves diode-pumped solid-state (DPSS) lasers, which are pulsed to apply force to fast moving debris, stopping it like a brake. EX-Fusion's signature laser fusion process also involves DPSS lasers, which strike the surface of a hydrogen fuel pellet just millimeters in diameter, compressing it to trigger a fusion reaction. This makes space debris removal a useful test along the path to commercializing the fusion technology.

Can Pumping CO2 Into California's Oil Fields Help Stop Global Warming? (yahoo.com) 83

America's Environmental Protection Agency "has signed off on a California oil company's plans to permanently store carbon emissions deep underground to combat global warming," reports the Los Angeles Times: California Resources Corp., the state's largest oil and gas company, applied for permission to send 1.46 million metric tons of carbon dioxide each year into the Elk Hills oil field, a depleted oil reservoir about 25 miles outside of downtown Bakersfield. The emissions would be collected from several industrial sources nearby, compressed into a liquid-like state and injected into porous rock more than one mile underground.

Although this technique has never been performed on a large scale in California, the state's climate plan calls for these operations to be widely deployed across the Central Valley to reduce carbon emissions from industrial facilities. The EPA issued a draft permit for the California Resources Corp. project, which is poised to be finalized in March following public comments. As California transitions away from oil production, a new business model for fossil fuel companies has emerged: carbon management. Oil companies have heavily invested in transforming their vast network of exhausted oil reservoirs into a long-term storage sites for planet-warming gases, including California Resources Corp., the largest nongovernmental owner of mineral rights in California...

[Environmentalists] say that the transportation and injection of CO2 — an asphyxiating gas that displaces oxygen — could lead to dangerous leaks. Nationwide, there have been at least 25 carbon dioxide pipeline leaks between 2002 and 2021, according to the U.S. Department of Transportation. Perhaps the most notable incident occurred in Satartia, Miss., in 2020 when a CO2 pipeline ruptured following heavy rains. The leak led to the hospitalization of 45 people and the evacuation of 200 residents... Under the EPA draft permit, California Resources Corp. must take a number of steps to mitigate these risks. The company must plug 157 wells to ensure the CO2 remains underground, monitor the injection site for leaks and obtain a $33-million insurance policy.

Canadian-based Brookfield Corporation also invested $500 million, according to the article, with California Resources Corp. seeking permits for five projects — more than any company in the nation. "It's kind of reversing the role, if you will," says their chief sustainability officer. "Instead of taking oil and gas out, we're putting carbon in."

Meanwhile, there's applications for "about a dozen" more projects in California's Central Valley that could store millions of tons of carbon emissions in old oil and gas fields — and California Resources Corp says greater Los Angeles is also "being evaluated" as a potential storage site.

Private US Moon Lander Now Headed For Earth, Might Burn Up In Atmosphere (ndtv.com) 41

The fuel-leaking Peregrine lunar lander is now "on a parth towards Earth," according to Update #16 from Astrobotic, which predicts their spacecraft "will likely burn up in the Earth's atmosphere." "Our analysis efforts have been challenging due to the propellant leak... The team is currently assessing options and we will update as soon as we are able. The propellant leak has slowed considerably to a point where it is no longer the teams' top priority...

We have now been operating in space for 5 days and 8 hours and are about 242,000 miles from Earth.

"A soft landing on the Moon is not possible," the announcement emphasizes. NDTV explains: Shortly after it separated from the rocket, the spaceship experienced an onboard explosion and it soon became clear it would not make a soft lunar touchdown because of the amount of the propellant it was losing — though Astrobotic's team were able to power up science experiments they were carrying for NASA and other space agencies, and gather spaceflight data...

Astrobotic itself will get another chance in November with its Griffin lander transporting NASA's VIPER rover to the lunar south pole.
