Take a look at what being called "a stunning phenomenon," captured in a photo taken from the International Space Station as it passed above a thunderstorm over Mexico and the American Southwest.

So what was it? "A rare form of Transient Luminous Event (TLE) called a gigantic jet," according to a new blog post at Notebookcheck.net: A gigantic jet happens above thunderstorms, firing powerful bursts of electrical charge from the top of the thunderstorm (about 20 km [12.4 miles] above the ground) into the upper atmosphere (about 100 km [62.1 miles] above the ground). The upper part of gigantic jets produces red emissions identical to sprites [large-scale electric discharges above thunderclouds]. But while gigantic jets burst directly from the top of thunderstorms, sprites form independently, much higher in the atmosphere, appearing around 50 miles (80 km) above the Earth's surface.
"If ordinary lightning seems pretty ordinary, upper-atmosphere lightning is something else — an entire zoo of various upper-atmosphere electrical discharges," writes the Severe Weather Europe site.

And NASA made a request in a new blog post this week to any aspiring citizen scientists. "Have you captured an image of a jet, sprite, or other type of TLE? Submit your photos to Spritacular.org to help scientists study these fascinating night sky phenomena!"

From the French newspaper Le Monde: Odorless, quiet, sustainable. On the last day of July, passengers boarded Barcelona's V3 bus line with no idea where its fuel came from. Written in large letters on the bus facade, just below its name "Nimbus," a sign clearly stated: "This bus runs on biomethane produced from eco-factory sludge." Still, the explanation was likely too vague for most to grasp its full meaning. The moist matter from wastewater treated at the Baix Llobregat treatment plant was used to produce the biomethane. In other words: the human waste of more than 1.5 million residents of the Catalan city.

"The planet Uranus emits more heat than it gets from the Sun," reports Science Daily , citing a new study led by University of Houston researchers, in collaboration with planetary scientists worldwide. "This means it's still slowly losing leftover heat from its early history," says the first author on the paper, "a key piece of the puzzle that helps us understand its origins and how it has changed over time."

The study found the planet emitting about 12.5% more heat than it absorbs via sunlight, which "suggests Uranus does have its own internal heat — an advance that not only informs NASA's future missions but also deepens scientists' understanding of planetary systems, including processes that influence Earth's climate and atmospheric evolution." The discovery resolves a long-standing scientific mystery about the giant planet, because observational analyses from Voyager 2 in 1986 didn't suggest the presence of significant internal heat — contradicting scientists' understanding of how giant planets form and evolve...

Additionally, the team's methodology provides testable theories and models that could also be applied to explore radiant energy of other planets within and beyond our solar system... It could even impact technology innovation and climate understanding on Earth [giving insights into "the fundamental processes that shape planetary atmospheres, weather systems and climate systems," said one of the paper's authors.]
The article adds that the researchers now think the planet "may have a different interior structure or evolutionary history compared to the other giant planets."

Scientists in Svalbard warn Arctic glaciers are in "terminal" decline, with microbe-driven biological darkening accelerating ice melt and potentially triggering major climate feedback loops. The Guardian reports: Recent research implicates snow and ice-dwelling microbes in positive feedback loops that can accelerate melting. With more than 70% of the planet's freshwater stored in ice and snow -- and billions of lives sustained by glacier-fed rivers -- this has profound implications everywhere. Yet not all polar microbes amplify global heating. Emerging evidence suggests that certain populations are -- for now -- applying a brake to methane emissions. [...] Microbes that live in surface ice and snow produce dark-colored pigments to harness sunlight and shield themselves from damaging UV light. They also trap dark-colored dust and debris. Together, these factors darken snow and ice, causing it to absorb more heat and melt faster -- a process known as "biological darkening."

Microbes also respond to global changes, such as increased nutrients from air pollution, wildfire smoke or wind-blown dust from receding glaciers and expanding drylands. "The snowpack chemistry is now different to preindustrial era snow," Edwards says. Rising temperatures and longer melt seasons caused by global heating further accelerate the growth of ice-darkening microbes. Together, these factors have the potential to trigger an amplifying positive feedback loop: ice-darkening microbes nudge up temperatures and accelerate melt, exposing more nutrient-rich debris that encourage the growth of yet more microbes, which darken the surface further still.

Each summer, a biologically darkened zone, visible from space, covering at least 100,000 sq km, appears on the south-western part of the Greenland ice sheet. According to a 2020 study, microbes there are responsible for 4.4 to 6.0-gigatons of runoff, representing up to 13% of total melt, from an ice mass that holds enough water to raise global sea levels by more than 7 meters. These effects are acknowledged in IPCC reports but not yet incorporated into climate projection models. Across the European Alps, Himalayas, central Asia and beyond, at least 2 billion people depend on glacial meltwater for drinking water, agriculture and hydropower. Yet even if the world meets Paris targets, half these glaciers will not survive this century.

Croatia has extended its digital nomad visa from one year to up to three years, allowing non-EU residents and their close family members to live and work remotely in the country. CNBC reports: A digital nomad visa is a short-term permit that allows individuals to stay in a country for an extended period and work remotely. The length of time a nomad can stay varies from place to place but most countries allow for six months to a year -- unless you have your eye on Croatia. Recently, the Balkan country announced it an update its digital nomad visa, which will allow non-EU residents to stay for up to three years. The visa also permits close family members of a digital nomad to join them.

Croatia's digital nomad visa website states that close family members also include partners or non-married couples who have been together for longer than three years without children, or for less time if they do have children together. Madrid Sartoretto believes that Croatia's expansion of its digital nomad program is a sign that the country is trying to attract more talent and compete with neighboring countries and their offerings.

"I think they are competing with other countries that are in the same region, like Estonia and Romania, that also attract a lot of digital nomads. If you give more benefits to people to come to your country, then you attract more talent. It's all about competition now," she adds. For those looking to apply for Croatia's digital nomad visa, Dr. Madrid Sartoretto says the country offers a low cost of living but still needs to improve its infrastructure, like more reliable internet speeds. "If you compare internet speed and reliability to countries like Romania, which has one of the fastest speeds in the world, Croatia needs to improve its infrastructure," she adds.

To apply for Croatia's digital nomad visa online, applicants must provide proof that they work outside of Croatia. Additionally, they must provide a copy of a valid travel document, proof of health insurance, proof of address in Croatia, and a minimum monthly income of 3,295 euros or $3,855 USD. For proof of income, applicants can submit a bank statement showing the total amount required, a bank statement demonstrating regular income, or pay slips for at least six months. Applicants must also send evidence that they have not been convicted of criminal offences in their home country or the country in which they have resided for more than a year immediately before arriving in Croatia.

alternative_right shares a report from ScienceAlert: In February 2023, a detector called KM3NeT, located deep under the Mediterranean Sea, picked up a signal that seemed to indicate a neutrino with a record-shattering energy of 220 petaelectronvolts (PeV). For reference, the previous record was a mere 10 PeV. Now, an exhaustive analysis of all the data on and around the event, designated KM3-230213A, not only supports the conclusions that the signal was caused by a 220-PeV neutrino, but adds to the mystery about where the heck in the Universe it came from."The patterns of light detected for KM3-230213A show a clear match to what is expected from a relativistic particle crossing the detector, most likely a muon, ruling out the possibility of a glitch," the KM3NeT Collaboration told ScienceAlert. "Thanks to the reconstructed energy and direction of this muon, the most likely scenario by far is that the muon originated in the interaction of an astrophysical neutrino in proximity to the detector, making it the most natural explanation."

The scientists believe that it's very, very unlikely that the neutrino originated within the Milky Way galaxy. Work is underway to come closer to tracing its origin point. "KM3-230213A opened a new window on ultra-high-energy neutrino astronomy," the Collaboration said. "Our analysis is the first effort to combine the observations of multiple telescopes over a wide energy range to characterize the ultra-high-energy spectrum. This represents our best chance to gain knowledge on the most extreme objects that populate our Universe."

The research has been published in the journal Physical Review X.

The African Union has endorsed the "Correct The Map" campaign, urging governments and global institutions to replace the distorted 16th-century Mercator projection with the Equal Earth map that more accurately represents Africa's true size. Reuters reports: "It might seem to be just a map, but in reality, it is not," AU Commission deputy chairperson Selma Malika Haddadi told Reuters, saying the Mercator fostered a false impression that Africa was "marginal," despite being the world's second-largest continent by area, with 54 nations and over a billion people. Such stereotypes influence media, education and policy, she said. Criticism of the Mercator map is not new, but the 'Correct The Map' campaign led by advocacy groups Africa No Filter and Speak Up Africa has revived the debate, urging organizations to adopt the 2018 Equal Earth projection, which tries to reflect countries' true sizes.

"The current size of the map of Africa is wrong," Moky Makura, executive director of Africa No Filter, said. "It's the world's longest misinformation and disinformation campaign, and it just simply has to stop." Fara Ndiaye, co-founder of Speak Up Africa, said the Mercator affected Africans' identity and pride, especially children who might encounter it early in school. "We're actively working on promoting a curriculum where the Equal Earth projection will be the main standard across all (African) classrooms," Ndiaye said, adding she hoped it would also be the one used by global institutions, including Africa-based ones. [...]

The Mercator projection is still widely used, including by schools and tech companies. Google Maps switched from Mercator on desktop to a 3D globe view in 2018, though users can still switch back to the Mercator if they prefer. On the mobile app, however, the Mercator projection remains the default. 'Correct The Map' wants organizations like the World Bank and the United Nations to adopt the Equal Earth map. A World Bank spokesperson said they already use the Winkel-Tripel or Equal Earth for static maps and are phasing out Mercator on web maps.

Negotiations on a global treaty to end plastic pollution are drawing to a close Thursday, as nations remain deadlocked over whether to tackle the exponential growth of plastic production. From a report: A draft of the treaty released Wednesday wouldn't limit plastic production or address chemicals used in plastic products. Instead, it's centered on proposals where there's broad agreement -- such as reducing the number of problematic plastic products that often enter the environment and are difficult to recycle, promoting the redesign of plastic products so they can be recycled and reused, and improving waste management.

It asks nations to make commitments to ending plastic pollution, rather than imposing global, legally-binding rules. French President Emmanuel Macron said the "lack of ambition" in the draft treaty was unacceptable, and that agreeing to a global treaty against plastic pollution "is our opportunity to make a difference."

Extreme heat is breaking temperature records across Europe, early measurements suggest, and driving bigger and stronger wildfires. From a report: In south-west France, records were broken on Monday in Angouleme, Bergerac, Bordeaux, Saint-Emilion and Saint-Girons. Meteo France said the "often remarkable, even unprecedented, maximum temperatures" in the region were 12C above the norm for the last few decades.

In Croatia, air temperature records were set in Sibenik, at 39.5C, and Dubrovnik, at 38.9C, while large forest fires raged along its coasts and ripped through neighbouring countries in the Balkans. The day before, Hungary broke its daily maximum temperature record when a weather station in Korosladany hit 39.9C. The capital, Budapest, also broke its daily maximum record as it sweltered through 38.7C heat.

Beyond Europe, dozens of temperature records were broken across Canada, and record-breaking heat above 50C in Iraq was blamed for a nationwide blackout. The heatwave in southern Europe comes as Nordic countries recover from unprecedentedtemperatures above 30C in the Arctic Circle this month.

An anonymous reader shares a report: Can deleting old emails and photos help the UK tackle ongoing drought this year? That's the hope, according to recommendations for the public included in a press release today from the National Drought Group.

There are far bigger steps companies and policymakers can take to conserve water of course, but drought has gotten bad enough for officials to urge the average person to consider how their habits might help or hurt the situation. And the proliferation of data centers is raising concerns about how much water it takes to power servers and keep them cool.

"Simple, everyday choices -- such as turning off a tap or deleting old emails -- also really helps the collective effort to reduce demand and help preserve the health of our rivers and wildlife," Helen Wakeham, Environment Agency Director of Water, said in the press release.

After four weather-related delays, Amazon successfully launched 24 more Kuiper internet satellites aboard a SpaceX Falcon 9, bringing its total to 102. CNBC reports: SpaceX's Starlink is currently the dominant provider of low-earth orbit satellite internet, with a constellation of roughly 8,000 satellites and about 5 million customers worldwide. Amazon is racing to get more of its Kuiper satellites into space to meet a deadline set by the Federal Communications Commission. The FCC requires that Amazon have about 1,600 satellites in orbit by the end of July 2026, with the full 3,236-satellite constellation launched by July 2029.

Amazon has booked up to 83 launches, including three rides with SpaceX. While the company is still in the early stages of building out its constellation, Amazon has already inked deals with governments as it hopes to begin commercial service later this year.

Biochar produced from solid human excrement could supply up to 7% of global phosphorus fertilizer needs annually, according to a Cornell University study published in PNAS. When combined with nutrients extracted from urine, the process could provide 15% of phosphorus, 17% of nitrogen, and 25% of potassium used in agriculture worldwide.

The biochar production process reduces solid waste volume and weight by up to 90%, while allowing nutrient proportions to be adjusted for specific crop requirements.

Imagine this. Lightning sparks a wildfire, but "within seconds, a satellite dish swirling overhead picks up on the anomaly and triggers an alarm," writes the Los Angeles Times. "An autonomous helicopter takes flight and zooms toward the fire, using sensors to locate the blaze and AI to generate a plan of attack. It measures the wind speed and fire movement, communicating constantly with the unmanned helicopter behind it, and the one behind that. Once over the site, it drops a load of water and soon the flames are smoldering. Without deploying a single human, the fire never grows larger than 10 square feet.

"This is the future of firefighting." On a recent morning in San Bernardino, state and local fire experts gathered for a demonstration of the early iterations of this new reality. An autonomous Sikorski Black Hawk helicopter, powered by technology from Lockheed Martin and a California-based software company called Rain, is on display on the tarmac of a logistics airport in Victorville — the word "EXPERIMENTAL" painted on its military green-black door. It's one of many new tools on the front lines of firefighting technology, which experts say is evolving rapidly as private industry and government agencies come face-to-face with a worsening global climate crisis...

Scientific studies and climate research models have found that the number of extreme fires could increase by as much as 30% globally by 2050. By 2100, California alone could see a 50% increase in wildfire frequency and a 77% increase in average annual acres burned, according to the state's most recent climate report. That's largely because human-caused climate change is driving up temperatures and drying out the landscape, priming it to burn, according to Kate Dargan Marquis, a senior advisor with the Gordon and Betty Moore Foundation who served as California's state fire marshal from 2007 to 2010.... "[T]he policies of today and the technologies of today are not going to serve us tomorrow."

Today, more than 1,100 mountaintop cameras positioned across California are already using artificial intelligence to scan the landscape for the first sign of flames and prompt crews to spring into action. NASA's Earth-observing satellites are studying landscape conditions to help better predict fires before they ignite, while a new global satellite constellation recently launched by Google is helping to detect fires faster than ever before.
One 35-year fire service veteran who consults on fire service technologies even predicts fire-fighting robots will also be used in high-risk situations like the Colossus robot that battled flames searing through Notre-Dame Cathedral in Paris...

And a bill moving through California's legislation "would direct the California Department of Forestry and Fire Protection to establish a pilot program to assess the viability of incorporating autonomous firefighting helicopters in the state."

"It sounds like science fiction: a spacecraft, no heavier than a paperclip, propelled by a laser beam," writes this report from ScienceDaily, "and hurtling through space at the speed of light toward a black hole, on a mission to probe the very fabric of space and time and test the laws of physics."

"But to astrophysicist and black hole expert Cosimo Bambi, the idea is not so far-fetched." Reporting in the Cell Press journal iScience, Bambi outlines the blueprint for turning this interstellar voyage to a black hole into a reality... "We don't have the technology now," says author Cosimo Bambi of Fudan University in China. "But in 20 or 30 years, we might." The mission hinges on two key challenges — finding a black hole close enough to target and developing probes capable of withstanding the journey.

Previous knowledge on how stars evolve suggests that there could be a black hole lurking just 20 to 25 light-years from Earth, but finding it won't be easy, says Bambi. Because black holes don't emit or reflect light, they are virtually invisible to telescopes... "There have been new techniques to discover black holes," says Bambi. "I think it's reasonable to expect we could find a nearby one within the next decade...."

Bambi points to nanocrafts — gram-scale probes consisting of a microchip and light sail — as a possible solution. Earth-based lasers would blast the sail with photons, accelerating the craft to a third of the speed of light. At that pace, the craft could reach a black hole 20 to 25 light-years away in about 70 years. The data it gathers would take another two decades to get back to Earth, making the total mission duration around 80 to 100 years... Bambi notes that the lasers alone would cost around one trillion euros today, and the technology to create a nanocraft does not yet exist. But in 30 years, he says that costs may fall and technology may catch up to these bold ideas.
"If the nanocraft can travel at a velocity close to the speed of light, the mission could last 40-50 years," Bambi writes in the article, while acknowledging his idea is certainly very speculative and extremely challenging..."

"However, we should realize that most of the future experiments in particle physics and astrophysics will likely require long time (for preparation, construction, and data collection) and the work of a few generations of scientists, be very expensive, and in many cases, we will not have other options if we want to make progress in a certain field."

The BBC reports: A meteorite that crashed into a home in the U.S. is older than planet Earth, scientists have said...

Researchers at the University of Georgia examined a fragment of the rock that pierced the roof of a home in the city of McDonough [30 miles south of Georgia, on June 26]. They found that, based on the type of meteorite, it is expected to have formed 4.56 billion years ago, making it roughly 20 million years older than Earth... The rock quickly diminished in size and speed, but still travelled at least 1 km per second, going through a man's roof in Henry County...

Using optical and electron microscopy, Scott Harris [a Univeristy of Georgia geologist] and his team determined the rock was a chondrite — the most abundant type of stony meteorite, according to NASA — which meant that it was approximately 4.56 billion years old.
"The home's resident said he is still finding pieces of space dust around his home from the hit."

After five months on the International Space Station, four astronauts splashed down in the Pacific Ocean in a SpaceX Crew Dragon capsule named Endurance, reports Space.com.

It was NASA's 10th commercial crew rotation mission: The flight launched atop a SpaceX Falcon 9 rocket on March 14 and arrived at the orbiting lab two days later. Crew-10's four astronauts soon set to conducting science work, which consumed much of their time over the ensuing months... The wheels for Crew-10's departure began turning last Saturday (Aug. 2), when SpaceX's four-person Crew-11 mission arrived at the International Space Station. The Crew-10 astronauts spent a few days advising their replacements, then set their minds to gearing up for the return to Earth — and reflecting on their orbital experience.

"We got to accomplish a lot of really amazing operational things," Ayers said during a farewell ceremony on Tuesday (Aug. 5). "We got to see some amazing views, and we have had some really big belly laughs and a wonderful time together," she added. "I think that [we're] leaving with a heart full of gratitude, and [we're] excited to see where the International Space Station goes after we get home." The hatches between Endurance and the ISS closed on Friday (Aug. 8) at 4:20 p.m. EDT (2020 GMT), and the capsule undocked about two hours later, at 6:15 p.m. EDT (2205 GMT). Endurance then began maneuvering its way back to Earth, setting up its splashdown today.

It was the first Pacific Ocean return for a SpaceX CCP mission; all previous such flights have come down off the Florida coast. SpaceX recently shifted to West Coast reentries for all of its Dragon missions, both crewed and uncrewed, to minimize the chance that falling space debris could damage property or injure people.
"During their mission, crew members traveled nearly 62,795,205 million miles," NASA announced, "and completed 2,368 orbits around Earth..." Along the way, Crew-10 contributed hundreds of hours to scientific research, maintenance activities, and technology demonstrations. McClain, Ayers, and Onishi completed investigations on plant and microalgae growth, examined how space radiation affects DNA sequences in plants, observed how microgravity changes human eye structure and cells in the body, and more. The research conducted aboard the orbiting laboratory advances scientific knowledge and demonstrates new technologies that enable us to prepare for human exploration of the Moon and Mars.

McClain and Ayers also completed a spacewalk on May 1, relocating a communications antenna, beginning the installation of a mounting bracket for a future International Space Station Roll-Out Solar Array, and other tasks.

A professional trapper had one question about the wild pig he'd found in California. Why was its flesh blue? The Los Angeles Times explains: [California's Department of Fish and Wildlife] is now warning trappers and hunters to keep an eye out for possibly contaminated wildlife in the area, and not to consume the tainted meat, over concerns the blue meat is a sign that the animal may have consumed poison.... The startling find of wild pigs with bright blue tissue in Monterey County suggests the animals have been exposed to anticoagulant rodenticide diphacinone, a popular poison used by farmers and agriculture companies to control the population of rats, mice, squirrels and other small animals, according to a statement from the California Department of Fish and Wildlife. "Hunters should be aware that the meat of game animals, such as wild pig, deer, bear and geese, might be contaminated if that game animal has been exposed to rodenticides," said Ryan Bourbor, pesticide investigations coordinator with the state agency.
Diphacinone has been prohibited in California since 2024 (with exceptions for government agencies sor their certified Vector Control Technicians).

The state's Fish and Wildlife department says anyone who finds wildlife with blue fat or tissue should contact the state's wildlife officials.

They haven't built a spacecraft for travelling to our nearest star system. But "Engineers have designed a spacecraft that could take up to 2,400 people on a one-way trip to Alpha Centauri," reports LiveScience: The craft, called Chrysalis, could make the 25 trillion mile (40 trillion kilometer) journey in around 400 years, the engineers say in their project brief, meaning many of its potential passengers would only know life on the craft. Chrysalis is designed to house several generations of people until it enters the star system, where it could shuttle them to the surface of the planet Proxima Centuri b — an Earth-size exoplanet that is thought to be potentially habitable.

The project won first place in the Project Hyperion Design Competition, a challenge that requires teams to design hypothetical multigenerational ships for interstellar travel.

Before boarding the ship, the Chrysalis project would require initial generations of ship inhabitants to live in and adapt to an isolated environment in Antarctica for 70 to 80 years to ensure psychological wellbeing. The ship could theoretically be constructed in 20 to 25 years and retains gravity through constant rotation. The vessel, which would measure 36 miles (58 km) in length, would be constructed like a Russian nesting doll, with several layers encompassing each other around a central core. The layers include communal spaces, farms, gardens, homes, warehouses and other shared facilities, each powered by nuclear fusion reactors....

This plan is purely hypothetical, as some of the required technology, like commercial nuclear fusion reactors, don't yet exist.

"My first thought was that someone read Arthur C. Clarke's book, Rendezvous with Rama and used it as a model design!"

"California's biggest electric utilities pulled off a record-breaking test..." reports Semafor, "during the 7pm-9pm window that is typically its time of peak demand as people come home from work." Pacific Gas & Electric and other top California power companies switched on residential batteries in more than 100,000 homes and drew power from them into the broader statewide grid. The purpose of the test — the largest ever in the state, which has by far the most home battery capacity in the U.S. — was to see just how much power is really there for the utility to tap, and to ensure it could be switched on, effectively running the grid in reverse, without causing a crash.

The result, which the research firm Brattle published this week, was 535 megawatts, equal to adding a big hydro dam or a half-sized nuclear reactor at a fraction of the cost. "Four years ago this capacity didn't even exist," Kendrick Li, PG&E's director of clean energy programs, told Semafor. "Now it's a really attractive option for us. It would be silly not to harness what our customers have installed...." Last week's test proved that in times of peak demand, PG&E can lean on its customers' batteries rather than turn on a gas-fired peaker plant or risk a blackout, Li said.

Virtual power plants (VPPs) also facilitate the addition of more solar energy on the grid: At the moment, California has so much solar generation at peak hours that it can push the wholesale power price close to or even below zero, a headache for grid managers and a disincentive for renewable project developers. The careful manipulation of networked residential batteries smooths out the timing disparity between peak sunshine at midday and peak demand in the evening, allowing the excess to be soaked up and redeployed when it's actually needed, and making power cheaper for everyone. The expanded use of VPPs shouldn't be noticeable to battery owners, Li said, except for the money back on their power bill; nothing about the process prevents them from running their AC or dishwasher while their battery is being tapped. The network can also run in reverse, with the utility taking excess power from the grid at times of low demand and sending it into home batteries for storage.

California could easily reach over a gigawatt of VPP capacity within five years, Li said. Nationwide, a Department of Energy study during the Biden administration forecast that VPP capacity could reach up to 160 gigawatts by 2030, essentially negating the need for dozens of new fossil fuel power plants, with no emissions and at a far lower cost. In 2024, utilities in 34 states moved to initiate or expand VPP networks, according to the advocacy group VP3.
Even with a reduction in federal credits, virtual power plants "offer a way for residential solar-plus-storage systems to remain economically attractive for homeowners — who get paid for the withdrawn power," the article points out — and "a way to make better use of clean energy resources that have already been built."

Sunrun's distributed battery fleet "delivered more than two-thirds of the energy," notes Electrek, "In total, the event pumped an average of 535 megawatts (MW) onto the grid — enough to power over half of San Francisco... This isn't a one-off. Sunrun's fleet already helped drop peak demand earlier this summer, delivering 325 MW during a similar event on June 24.

"The company compensates customers up to $150 per battery per season for participating."

NASA's Crew-10 mission has departed the International Space Station after 146 days, with astronauts Nichole Ayers, Anne McClain, Takuya Onishi, and Kirill Peskov set to splash down off California's coast on Saturday morning. You can watch a recording of the SpaceX Crew-10 undocking and departure on X. Reuters reports: The four-person crew launched to the ISS on March 14 in a routine mission that replaced the Crew-9 crew, which included NASA astronauts Butch Wilmore and Suni Williams, the astronaut pair left on the station by Boeing's Starliner capsule. Five months after the Starliner mission's conclusion, Wilmore this week retired from NASA after a 25-year career in which he flew four different spacecraft and logged a total of 464 days in space. Wilmore was a key technical adviser to Boeing's Starliner program along with Williams, who remains at the agency in its astronaut corps. [...] NASA said they are returning to Earth with "important and time-sensitive research" conducted in the microgravity environment of the ISS during the 146-day mission. The astronauts had over 200 science experiments on their to-do list.
