To complete one full rotation around its axis it takes the moon 655 hours. So a single "lunar day" is 13.64 earth days.

But sunset has finally come for India's Chandrayaan-3 spacecraft and its Pragyan rover, writes long-time Slashdot reader Geoffrey.landis , and the rover has switched off for the coming 655-hour night: With luck from the moon gods, it will wake up with the sunrise in 14 days. But, even if not, mission accomplished! It was designed for fourteen days of operation, the daylight period. In that time the rover accomplished just over a hundred meters (American units: one football field) of traverse, examining and chemically analyzing the surface.
"The Indian Express newspaper said the electronics on board the Indian moon mission werenâ(TM)t designed to withstand very low temperatures, less than -120 C (-184 F) during the nighttime on the moon," according to the Associated Press. But the rover's accomplishments already include making the first-ever measurements of the south pole's near-surface Lunar plasma, and confirming the presence of aluminum, calcium, chromium, titanium, manganese, and silicon. There's also sulphur, iron, oxygen and other elements on the moon, Reuters reports, citing a statement from the Indian Space Research Organisation (ISRO): The Pragyan rover from the Chandrayaan-3 spacecraft was "set into Sleep mode" but with batteries charged and receiver on, the ISRO said in a post on X, formerly Twitter, late on Saturday. "Hoping for a successful awakening for another set of assignments!" ISRO said. "Else, it will forever stay there as India's lunar ambassador."
Earlier this week the ISRO posted footage of the rover completing a near-pirouette to search for the safest route.

"The solar panel is oriented to receive the light at the next sunrise expected on September 22, 2023," the ISRO posted Saturday.

Hot on the heels of its lunar landing success, India is readying to blast a probe even deeper into space to study the sun. From a report: The country's first solar observation mission, named Aditya-L1, is set to be launched from India's main spaceport on Sriharikota, an island off the southern state of Andhra Pradesh, at 11:50 a.m. local time on Saturday. The spacecraft is scheduled to spend 125 days traveling 1.5 million kilometers (932,000 miles) to its destination, a point in space where objects stay put and consume less fuel.

While arriving there would be an impressive achievement for ISRO, the Indian space agency, Aditya-L1 would have gone just a fraction of the 150 million km between Earth and the sun. For ISRO, success would be another major feat after India became the first country to land a spacecraft close to the lunar south pole in August. India has more ambitious projects in the works. A human spaceflight program aims to launch astronauts into orbit for the first time possibly by 2025, ISRO Chairman S Somanath said in an interview with news agency Asian News International. ISRO and NASA plan to cooperate on sending astronauts to the International Space Station and India is in discussions with Japan to work together on a mission.

The stakes are high for Bethesda's newest role-playing game. Microsoft needs an Xbox hit, and players are hungry for an expansive and satisfying space adventure. From a report: Starfield almost immediately nudges its players to the edges of the cosmos. In the opening hours of the role-playing video game, it's possible to land your spaceship on Earth's moon or zip 16 light-years to Alpha Centauri. When you open your map and zoom out from a planet, you can behold its surrounding solar system; zoom out again, and you're scrolling past luminous stars and the mysterious worlds that orbit them. That sprawling celestial journey within Starfield, developed by Bethesda Game Studios, reveals both the tremendous potential and the monumental challenge of an open-world space adventure. Bethesda has hyped an expansive single-player campaign with 1,000 explorable planets. And expectations around the game, officially releasing on Sept. 6 after a 10-month delay, are nearly as vast.

It's the first new universe in 25 years for Bethesda, known for the Elder Scrolls and Fallout series. It's also a high-stakes moment for Microsoft, which makes the Xbox and has long faced criticism that it produces fewer hit games than its console rivals, Sony and Nintendo. To compete, Microsoft went on a spending spree, acquiring Bethesda's parent company in 2020 and agreeing to purchase Activision Blizzard in 2022, a $69 billion bet that is being challenged by regulators. Now Bethesda must deliver. Known for letting players navigate competing factions and undertake eccentric quests, the studio hopes Starfield will dazzle those clamoring for engaging encounters with alien life-forms or space mercenaries as well as a sense of boundless exploration.

An anonymous reader quotes a report from Ars Technica: NASA officials sounded an alarm Tuesday about the agency's Deep Space Network, a collection of antennas in California, Spain, and Australia used to maintain contact with missions scattered across the Solar System. Everything from NASA's Artemis missions to the Moon to the Voyager probes in interstellar space rely on the Deep Space Network (DSN) to receive commands and transmit data back to Earth. Suzanne Dodd, who oversees the DSN in her position at NASA's Jet Propulsion Laboratory, likes to highlight the network's importance by showing gorgeous images from missions like the James Webb Space Telescope and the Perseverance rover on Mars. "All these images, and all these great visuals for the public, and all the science for the scientists come down through the Deep Space Network," Dodd said Tuesday in a meeting of the NASA Advisory Council's Science Committee.

But Dodd doesn't take a starry-eyed view of the challenges operating the Deep Space Network. She said there are currently around 40 missions that rely on the DSN's antennas to stay in communication with controllers and scientists back on Earth. Another 40-plus missions will join the roster over the next decade or so, and many of the 40 missions currently using time on the network will likely still be operating over that time. "We have more missions coming than we currently are flying," Dodd said. "We're nearly doubling the load on the DSN. A lot of those are either lunar exploration or Artemis missions, and a lot of Artemis precursor missions with commercial vendors. So the load is increasing, and it's very stressful to us." "It's oversubscribed, yet it's vital to anything the agency wants to do," she said.

Vint Cerf, an Internet pioneer who is now an executive at Google, sits on the committee Dodd met with Tuesday. After hearing from Dodd and other NASA managers, Cerf said: "The deep space communications system is in deep -- well, let me use a better word, deficit. There's a four-letter word that occurs to me, too." Because astronauts are involved, the Artemis missions will come with unique requirements on the DSN. "We're not going to have bits of data. We're going to have gigabits of data," said Philip Baldwin, acting director of the network services division at JPL. "I don't want 1080p for video resolution. I want 8K video." Each of the three stations on the Deep Space Network has a 70-meter (230-foot) dish antenna, the largest antennas in the world for deep space communications. Each location also has at least three 112-foot (34-meter) antennas. The oldest of the large antennas in California entered service in 1966, then was enlarged to its 70-meter diameter in 1988. "We have reached a really critical point on the DSN's aging infrastructure," said Sandra Cauffman, deputy director of NASA's astrophysics division.

The word "funga" should be used alongside flora and fauna when discussing conservation issues to reflect the importance of fungi to ecosystem health, a UN body has said. From a report: The secretariat of the UN convention on biological diversity (UNCBD) said it was time that fungi were "recognised and protected on an equal footing with animals and plants in legal conservation frameworks."

"Whenever referring to the macroscopic diversity of life on Earth, we should use 'flora, fauna and funga,' and 'animal, plants and fungi,'" it said in an Instagram post. Mycologists, mostly from Latin America, established the term "funga" five years ago. It refers to the levels of diversity of fungi in any given place, and is analogous to "flora and fauna," which refer to plants and animals. Unlike flora and fauna, it is not a Latin term but was chosen because it is morphologically similar. "Just like mycelium, mycologically inclusive language will spread unseen but profound [sic], permeating public consciousness (and policy) to acknowledge fungi's vital role in the grand web of life on and in Earth," it said.

SonicSpike shares a report from NASA: In 2023, NASA is sending a technology demonstration known as the Integrated LCRD Low Earth Orbit User Modem and Amplifier Terminal (ILLUMA-T) to the space station. Together, ILLUMA-T and the Laser Communications Relay Demonstration (LCRD), which launched in December 2021, will complete NASA's first two-way, end-to-end laser relay system. With ILLUMA-T, NASA's Space Communications and Navigation (SCaN) program office will demonstrate the power of laser communications from the space station. Using invisible infrared light, laser communications systems send and receive information at higher data rates. With higher data rates, missions can send more images and videos back to Earth in a single transmission. Once installed on the space station, ILLUMA-T will showcase the benefits higher data rates could have for missions in low Earth orbit.

"Laser communications offer missions more flexibility and an expedited way to get data back from space," said Badri Younes, former deputy associate administrator for NASA's SCaN program. "We are integrating this technology on demonstrations near Earth, at the Moon, and in deep space." In addition to higher data rates, laser systems are lighter and use less power -- a key benefit when designing spacecraft. ILLUMA-T is approximately the size of a standard refrigerator and will be secured to an external module on the space station to conduct its demonstration with LCRD. Currently, LCRD is showcasing the benefits of a laser relay in geosynchronous orbit -- 22,000 miles from Earth -- by beaming data between two ground stations and conducting experiments to further refine NASA's laser capabilities. "Once ILLUMA-T is on the space station, the terminal will send high-resolution data, including pictures and videos to LCRD at a rate of 1.2 gigabits-per-second," said Matt Magsamen, deputy project manager for ILLUMA-T. "Then, the data will be sent from LCRD to ground stations in Hawaii and California. This demonstration will show how laser communications can benefit missions in low Earth orbit."

ILLUMA-T is launching as a payload on SpaceX's 29th Commercial Resupply Services mission for NASA. In the first two weeks after its launch, ILLUMA-T will be removed from the Dragon spacecraft's trunk for installation on the station's Japanese Experiment Module-Exposed Facility (JEM-EF), also known as "Kibo" -- meaning "hope" in Japanese. NASA's Laser Communications Roadmap. Following the payload's installation, the ILLUMA-T team will perform preliminary testing and in-orbit checkouts. Once completed, the team will make a pass for the payload's first light -- a critical milestone where the mission transmits its first beam of laser light through its optical telescope to LCRD. Once first light is achieved, data transmission and laser communications experiments will begin and continue throughout the duration of the planned mission.

Physicists have observed neutrinos originating "from the sun, cosmic rays, supernovae and other cosmic objects, as well as particle accelerators and nuclear reactors," writes Phys.org. But one remaining goal was observing neutrinos inside "collider" particle accelerators (which direct two particle beams).

It's now been accomplished using neutrino detectors located at CERN's Large Hadron Collider (LHC) in Switzerland by two distinct research collaborations:

- FASER (Forward Search Experiment)
- SND (Scattering and Neutrino Detector)@LHC

Phys.org argues the two achievements "could open important new avenues for experimental particle physics research. " The results of their two studies were recently published in Physical Review Letters. "Neutrinos are produced very abundantly in proton colliders such as the LHC," Cristovao Vilela, part of the SND@LHC Collaboration, told Phys.org. "However, up to now, these neutrinos had never been directly observed. The very weak interaction of neutrinos with other particles makes their detection very challenging and because of this they are the least well studied particles in the Standard Model of particle physics...."

"Particle colliders have existed for over 50 years, and have detected every known particle except for neutrinos," Jonathan Lee Feng, co-spokesperson of the FASER Collaboration, told Phys.org. "At the same time, every time neutrinos have been discovered from a new source, whether it is a nuclear reactor, the sun, the Earth, or supernovae, we have learned something extremely important about the universe. As part of our recent work, we set out to detect neutrinos produced at a particle collider for the first time...

"Because these neutrinos have high fluxes and high energies, which makes them far more likely to interact, we were able to detect 153 of them with a very small, inexpensive detector that was built in a very short time," Feng explained. "Previously, particle physics was thought to be divided into two parts: high energy experiments, which were required to study heavy particles, like top quarks and Higgs bosons, and high intensity experiments, which were required to study neutrinos. This work has shown that high energy experiments can also study neutrinos, and so has brought together the high-energy and high-intensity frontiers."

The neutrinos detected by Feng and the rest of the FASER collaboration have the highest energy ever recorded in a laboratory environment.... Cristovao Vilela, part of the SND@LHC Collaboration, said "The observation of collider neutrinos opens the door to novel measurements which will help us understand some of the more fundamental puzzles of the Standard Model of particle physics, such as why there are three generations of matter particles (fermions) that seem to be exact copies of each other in all aspects except for their mass. Furthermore, our detector is placed in a location which is a blind spot for the larger LHC experiments. Because of this, our measurements will also contribute to a better understanding of the structure of colliding protons."

Long-time Slashdot reader SonicSpike shares a new perspective on sunspots (those dark, cool areas where the sun's magnetic field is particularly strong, and which often launch solar flares).

"NASA's Perseverance Mars rover has given us a sneak peek of an intriguing patch of the sun that's not yet visible from Earth," reports Space.com: Perseverance photographs the sun daily with its Mastcam-Z camera system to gauge the amount of dust in the Martian atmosphere. Such an effort captured a big sunspot moving across the solar disk late last week and over the weekend, as SpaceWeather.com reported. "Because Mars is orbiting over the far side of the sun, Perseverance can see approaching sunspots more than a week before we do," SpaceWeather.com wrote in a post highlighting the sunspot photos. "Consider this your one-week warning: A big sunspot is coming...."

Solar flares and coronal mass ejections that hit Earth can affect satellite navigation and disrupt power grids, among other things, so tracking the movement of sunspots is more than just of academic interest.

Using data collected from the International Space Station (ISS), scientists found that a small yet growing percentage of tree leaves in tropical forests are approaching the maximum temperature threshold for leaves to photosynthesize," reports Live Science. If this trend continues, it could spell disaster for Earth's climate systems and biodiversity. The findings have been published in the journal Nature. From the report: The average critical temperature beyond which photosynthetic machinery in tropical trees begins to fail is 116 degrees Fahrenheit (46.7 degrees Celsius). Currently, only 0.01 % of all leaves surpass this critical temperature every year. But scientists warn that air temperature rises of 7.2 F (4 C) could push trees in tropical forests beyond a tipping point and into mass death. "It's concerning from our perspective that you see nonlinear trends. So you heat the air by, let's say, 2, 3 degrees Celsius [3.6 to 5.4 F], and the actual upper temperature of these leaves goes up by 8 degrees [Celsius; 14.4 F]," Christopher Doughty, an associate professor of ecoinformatics at Northern Arizona University, said during a press conference on Monday (Aug. 21). "Even though a small percentage of leaves are currently doing this, our best guess is that a 4 degrees Celsius increase in temperature could cause some serious issues for certain tropical forests." [...]

Plugging these peak temperatures into a mathematical model, the scientists found that an average 7 F (3.9 C) increase in the air temperature surrounding the leaves caused those most exposed to the heat to have their water-carrying stomata closed off by the tree, leading to their deaths. This triggered a cascade effect, increasing the temperature around the remaining leaves and potentially killing them, their branches and the trees in turn. "If you have 10% of the leaves dying, the whole branch is going to be warmer because a critical part of that branch can no longer cool the broader branch. Likewise you can make that assumption across the whole forest when a tree dies," Doughty said.

An anonymous reader quotes a report from The Guardian: Methane is a potent greenhouse gas emitted from energy (natural gas and petroleum systems), industry, agriculture, land use and waste management activities. Now a group of researchers from California University Long Beach are proposing a method of removing methane by using a group of bacteria known as methanotrophs to naturally convert methane to carbon dioxide and biomass. All the bacteria in this group "'eat' methane, removing it from air and converting part of it to cells as a source of sustainable protein," according to the lead researcher, Mary E Lidstrom. Lidstrom's team have found a strain of bacteria within this group called methylotuvimicrobium buryatense 5GB1C that can remove methane efficiently even when it is present in lower amounts. If it became widespread, the technology has the potential to help slow global heating, the researchers said.

Typically, this group of bacteria thrive in environments with high levels of methane (between 5,000 and 10,000 parts per million (ppm)). The normal concentrations in our atmosphere have much lower levels of only about 1.9 ppm of methane. But certain areas such as landfills, rice fields and oilwells emit higher concentrations of about 500 ppm. "Bacteria that rapidly eat methane at the higher concentrations found around cattle herds, etc could make a huge contribution to cutting methane emissions, especially from tropical agriculture," said Euan Nisbet, professor of Earth sciences at Royal Holloway, University of London, commenting on the findings of the study.

The strain's high methane consumption rate is probably due to a low energy requirement and greater attraction for methane – more than five times more than that of other bacteria, according to the study. "The bacteria oxidise the methane to CO2 (a much less powerful greenhouse gas) and so you can even use the exhaust to pump into greenhouses and grow tomatoes," said Nisbet. "The biggest barrier to implementation now is technical: we need to increase the methane treatment unit 20-fold. If we can achieve that, then the biggest barriers become investment capital and public acceptance. We believe we could have field pilots tested within three to four years, and scale up would then depend on investment capital and commercialization," said Lidstrom. The study has been published in the journal Proceedings of the National Academy of Sciences (PNAS).

A piece of space debris being monitored by the European Space Agency as part of a mission to remove trash from space was hit by another piece of debris, splintering the object into more pieces. From a report: ESA confirmed Tuesday that the US's 18th Space Defense Squadron, which tracks objects in orbit, spotted a number of new pieces in the vicinity of a payload adapter named VESPA that the agency had planned to pluck from space. The most likely cause of those new fragments is "the hypervelocity impact of a small, untracked object" ramming into VESPA, according to ESA. VESPA was left over from the launch of a European Vega rocket that took off from South America in 2013. It was part of a cone-shaped attachment used to deploy the rocket's satellite into orbit, and has been in Earth's orbit ever since. ESA said its new fragments don't pose much of a risk to any other spacecraft at the moment.

Under a new initiative, named Bandwagon, SpaceX is expanding its rideshare program to cater to the demand for launches to mid-inclination orbits. TechCrunch reports: Orbital inclination refers to what part of the Earth is visible to a satellite as it rotates around the planet. A satellite in an equatorial orbit is at 0 degrees inclination; a satellite in a sun-synchronous orbit (SSO) is slightly higher than 90 degrees; and a mid-inclination orbit is around 45 degrees. Currently, SpaceX offers rideshare services on the Falcon 9 rocket to SSO through the Transporter program, which is in notoriously high demand. But mid-inclination orbits (MIOs) are appealing to a growing number of customers, especially to remote sensing companies that want to strengthen their coverage over areas like parts of Asia and the Middle East. Right now, companies must often purchase a dedicated launch from Rocket Lab if they want to position a satellite in MIO.

With the new rideshare program, called Bandwagon, SpaceX is going after this slice of the market. According to SpaceX's website, it currently has two Bandwagon missions booked for 2024 and two for 2025. If they become even close to the popularity of the Rideshare program, they could be a major threat to all other small launch providers: According to Jarrod McLachlan, director of rideshare sales at SpaceX, who spoke at the industry conference, SpaceX has delivered 682 spacecraft to orbit to date via rideshare missions.

LiveScience brings an update on China's Chang'e-4 — the first spacecraft to ever land on the far side of the moon.

Its Lunar Penetrating Radar has now mapped the lunar subsurface "in finer detail than ever before" by bouncing radio signals deep underground: Their results, which were published Aug. 7 in the Journal of Geophysical Research: Planets, reveal billions of years of previously hidden lunar history. These new data suggest the top 130 feet of the lunar surface are made up of multiple layers of dust, soil, and broken rocks, said lead study author Jianqing Feng, an astrogeological researcher at the Planetary Science Institute in Tucson, Arizona... Farther down, the scientists discovered five distinct layers of lunar lava that seeped across the landscape billions of years ago.

Scientists think our moon formed 4.51 billion years ago, not long after the solar system itself, when a Mars-size object slammed into Earth and broke off a chunk of our planet The moon then continued to be bombarded by objects from space for roughly 200 million years. Some impacts cracked the moon's surface. Like Earth, the moon's mantle at that time contained pockets of molten material called magma, which seeped out through the newly formed cracks in a series of volcanic eruptions, Feng said.

The new data from Chang'e-4 shows that process slowing down over time: Feng and his colleagues found that the layers of volcanic rock grew thinner the closer they were to the moon's surface. This suggests that less lava flowed in later eruptions compared with earlier ones. "[The moon] was slowly cooling down and running out of steam in its later volcanic stage," Feng said. "Its energy became weak over time...."

However, there could still be magma deep underneath the lunar surface, Feng said.

China launched what is thought to be the world's first geosynchronous orbit synthetic aperture radar satellite on Saturday. SpaceNews reports: A Long March 3B rocket lifted off from Xichang Satellite Launch Center in southwest China at 1:36 p.m. Eastern (1736 UTC) Aug. 12. The Land Exploration-4 01 (Ludi Tance-4 (01)) satellite successfully entered geosynchronous transfer orbit, the China Aerospace Science and Technology Corp., (CASC) announced within an hour of liftoff. Few details of the satellite were provided by CASC. However the group's "blue book" outlining plans for 2023 released in January noted the launch of a "high-orbit 20-meter [resolution] SAR satellite."

The L-band synthetic aperture radar (SAR) satellite will provide all-day, all-weather observation of China and surrounding areas, boosting the country's disaster prevention, reduction, and relief capabilities. The land observation satellite series and "high-orbit SAR technology" are listed in the country's Medium and Long Term Development Plan for Civilian Space Infrastructure (2015-2025). The plan includes establishing high and medium resolution optical and synthetic aperture radar constellations for a range of land, marine and atmospheric monitoring. The series is separate from the China High-resolution Earth Observation System (CHEOS), which consists of Gaofen ("high resolution") satellites. China's Gaofen-4 satellite is a GEO optical satellite. SAR at GEO, while providing much lower resolution than satellites in low Earth orbit, can provide constant coverage and imagery despite cloud cover.

It is not yet known what orbital scheme the Land Exploration-4 (01) satellite will enter. An inclined GEO orbit would produce a "figure eight" ground track over the area of intended coverage. Chinese academics from the Beijing Institute of Technology have produced a study of various schemes, while others have published research into modified signal models for GEO SAR. The (01) designation suggests China could launch other SAR satellites into geosynchronous orbits. The satellite was developed by the China Academy of Spacecraft Technology (CAST.)

An anonymous reader quotes a report from Motherboard: The mysterious attacks began on July 11. "Strange beings," locals said, visiting an isolated Indigenous community in rural Peru at night, harassing its inhabitants and attempting to kidnap a 15-year-old girl. [...] News of the alleged extraterrestrial attackers quickly spread online as believers, skeptics, and internet sleuths around the world analyzed grainy videos posted by members of the Ikitu community. The reported sightings came on the heels of U.S. congressional hearings about unidentified aerial phenomenon that ignited a global conversation about the possibility of extraterrestrial life visiting Earth.

Members of the Peruvian Navy and Police traveled to the isolated community, which is located 10 hours by boat from the Maynas provincial capital of Iquitos, to investigate the strange disturbances in early August. Last week, authorities announced that they believed the perpetrators were members of illegal gold mining gangs from Colombia and Brazil using advanced flying technology to terrorize the community, according to RPP Noticias. Carlos Castro Quintanilla, the lead investigator in the case, said that 80 percent of illegal gold dredging in the region is located in the Nanay river basin, where the Ikitu community is located.

One of the key pieces to the investigation was related to the attempted kidnapping of a 15-year-old girl on July 29. Cristian Caleb Pacaya, a local teacher who witnessed the attack, said that they "were using state of the art technology, like thrusters that allow people to fly." He said that after looking the devices up on Google, he believed that they were "jetpacks." Authorities have not made any arrests related to the attacks, nor named the alleged assailants or their organization directly. However, the prosecutors office claimed that they had destroyed 110 dredging operations and 10 illegal mining camps in the area already in 2023.

British households are making more green energy upgrades than ever before after installing a record number of solar panels and heat pumps in the first half of the year, according to the industry's official standards body. From a report: The industry figures show there were more green energy installations in June than in previous years. On average, more than 17,000 households installed solar panels every month this year, while the number of homes installing heat pumps reached 3,000 a month for the first time, according to the data. Each month of 2023 was a record month for battery technologies, as installation figures consistently surpassed the month before, bringing the total number of batteries installed in homes and businesses across the UK to more than 1,000 in 2023 so far. The industry's accreditation body, MCS, said the green energy boom has put households on track to install more renewable energy than the last record set in 2012, when many raced to install solar panels before government subsidies were reduced.

In the first ruling of its kind nationwide, a Montana state court decided Monday in favor of young people who alleged the state violated their right to a "clean and healthful environment" by promoting the use of fossil fuels. From a report: The court determined that a provision in the Montana Environmental Policy Act has harmed the state's environment and the young plaintiffs, by preventing Montana from considering the climate impacts of energy projects. The provision is accordingly unconstitutional, the court said. The win, experts say, could energize the environmental movement and reshape climate litigation across the country, ushering in a wave of cases aimed at advancing action on climate change. "People around the world are watching this case," said Michael Gerrard, the founder of Columbia's Sabin Center for Climate Change Law.

The ruling represents a rare victory for climate activists who have tried to use the courts to push back against government policies and industrial activities they say are harming the planet. In this case, it involved 16 young Montanans, ranging in age from 5 to 22, who brought the nation's first constitutional and first youth-led climate lawsuit to go to trial. Though the cumulative number of climate cases around the world has more than doubled in the last five years, youth-led lawsuits in the United States have faced an uphill battle. Already, at least 14 of these cases have been dismissed, according to a July report from the United Nations Environment Program and the Sabin Center. The report said about three-quarters of the approximately 2,200 ongoing or concluded cases were filed before courts in the United States. Experts said the Montana youth had an advantage in the state's constitution, which guarantees a right to a "clean and healthful environment." Coal is critical to the state's economy, and Montana is home to the largest recoverable coal reserves in the country. The plaintiff's attorneys say the state has never denied a permit for a fossil fuel project.

Four years into a plan to eliminate its carbon emissions, Amazon has lost a key endorsement from the world's leading watchdog of corporate climate goals. From a report: The Science Based Targets initiative, a United Nations-backed entity that validates net zero plans, has removed Amazon from its list of companies taking action on climate goals after the tech behemoth failed to implement its commitment to set a credible target for reducing carbon emissions. The move raises questions around Amazon's status as a preferred stock among funds marketing themselves as ESG. The world's largest ESG exchange-traded fund, which is managed by BlackRock, lists Amazon among its top three holdings. The company is also held in over 900 ESG funds registered in the European Union alone, representing about 2% of outstanding shares, according to data compiled by Bloomberg.

An anonymous reader shared this report from The New York Times: More than $1.7 trillion worldwide is expected to be invested in technologies such as wind, solar power, electric vehicles and batteries globally this year, according to the International Energy Agency, compared with just over $1 trillion in fossil fuels. That is by far the most ever spent on clean energy in a year. Those investments are driving explosive growth. China, which already leads the world in the sheer amount of electricity produced by wind and solar power, is expected to double its capacity by 2025, five years ahead of schedule. In Britain, roughly one-third of electricity is generated by wind, solar and hydropower. And in the United States, 23 percent of electricity is expected to come from renewable sources this year, up 10 percentage points from a decade ago... [F]rom Beijing to London, Tokyo to Washington, Oslo to Dubai, the energy transition is undeniably racing ahead...

[C]lean energy became cheap far faster than anyone expected. Since 2009, the cost of solar power has plunged by 83 percent, while the cost of producing wind power has fallen by more than half. The price of lithium-ion battery cells fell 97 percent over the past three decades. Today, solar and wind power are the least expensive new sources of electricity in many markets, generating 12 percent of global electricity and rising... The rapid drop in costs for solar energy, wind power and batteries can be traced to early government investment and steady improvements over time by hundreds of researchers, engineers and entrepreneurs around the world. "The world has produced nearly three billion solar panels at this point, and every one of those has been an opportunity for people to try to improve the process," said Gregory Nemet, a solar power expert at the University of Wisconsin-Madison. "And all of those incremental improvements add up to something very dramatic." An equally potent force, along with the technological advances, has been an influx of money — in particular, a gusher since 2020 of government subsidies...

In the United States, President Biden signed a trio of laws during his first two years in office that allocated unprecedented funds for clean energy: A $1 trillion bipartisan infrastructure law provided money to enhance the power grid, buy electric buses for schools and build a national network of electric vehicle chargers... Combined, the three laws have prompted companies to announce at least $230 billion in manufacturing investments so far... The U.S. solar industry installed a record 6.1 gigawatts of capacity in the first quarter of 2023, a 47 percent increase over the same period last year. And those low costs have led many of the United States' biggest corporations, such as Alphabet, Amazon and General Motors, to purchase large amounts of wind and solar power...

An anonymous reader shared this report from CNBC: In an unmarked office building in Austin, Texas, two small rooms contain a handful of Amazon employees designing two types of microchips for training and accelerating generative AI. These custom chips, Inferentia and Trainium, offer AWS customers an alternative to training their large language models on Nvidia GPUs, which have been getting difficult and expensive to procure. "The entire world would like more chips for doing generative AI, whether that's GPUs or whether that's Amazon's own chips that we're designing," Amazon Web Services CEO Adam Selipsky told CNBC in an finterview in June. "I think that we're in a better position than anybody else on Earth to supply the capacity that our customers collectively are going to want...."

In the long run, said Chirag Dekate, VP analyst at Gartner, Amazon's custom silicon could give it an edge in generative AI...
With millions of customers, Amazon's AWS cloud service "still accounted for 70% of Amazon's overall $7.7 billion operating profit in the second quarter," CNBC notes. But does that give them a competitive advantage?

A technology VP for the service tells them "It's a question of velocity. How quickly can these companies move to develop these generative AI applications is driven by starting first on the data they have in AWS and using compute and machine learning tools that we provide." In June, AWS announced a $100 million generative AI innovation "center."

"We have so many customers who are saying, 'I want to do generative AI,' but they don't necessarily know what that means for them in the context of their own businesses. And so we're going to bring in solutions architects and engineers and strategists and data scientists to work with them one on one," AWS CEO Selipsky said... For now, Amazon is only accelerating its push into generative AI, telling CNBC that "over 100,000" customers are using machine learning on AWS today. Although that's a small percentage of AWS's millions of customers, analysts say that could change.

"What we are not seeing is enterprises saying, 'Oh, wait a minute, Microsoft is so ahead in generative AI, let's just go out and let's switch our infrastructure strategies, migrate everything to Microsoft.' Dekate said. "If you're already an Amazon customer, chances are you're likely going to explore Amazon ecosystems quite extensively."
