Programmer Gets Doom Running On a Space Satellite (zdnet.com) 28

An Icelandic programmer successfully ran Doom on the European Space Agency's OPS-SAT satellite, proving that the iconic 1993 shooter can now run not just everywhere on Earth -- but in orbit. ZDNet reports: Olafur Waage, a senior software developer from Iceland who now works in Norway, explained at Ubuntu Summit 25.10 how he, a self-described "professional keyboard typist" and maker of funny videos, ended up making what is perhaps the game's most outlandish port yet: Doom running on a real satellite in orbit, the European Space Agency (ESA) OPS-SAT satellite. OPS-SAT, a "flying laboratory" for testing novel onboard computing techniques, was equipped with an experimental computer approximately 10 times more powerful than the norm for spacecraft. Waag explained, "OPS-SAT was the first of its kind, devoted to demonstrating drastically improved mission control capabilities when satellites can fly more powerful onboard computers. The point was to break the curse of being too risk-averse with multi-million-dollar spacecraft." (The satellite was decommissioned in 2024.) [...]

Running Doom in orbit was partly a challenge of portability and partly a challenge of the limitations of space hardware and mission control. The on-board ARM dual-core Cortex-A9 processor, while hot stuff for space computing hardware (which tends to be low-powered and radiation-hardened), was slow even by Earth-bound standards. Waage chose Chocolate Doom 2.3, a popular open-source version of Doom, for its compatibility with the Ubuntu 18.04 Long Term Support (LTS) distro, which was already running on OPS-SAT. Besides, Waage noted, "We picked Chocolate Doom 2.3 because of the libraries available for 18.04 -- that was the last one that would actually build.

Updating software in orbit is extremely difficult, so relatively little code would have to be uploaded. As Waage said, "Doom is relatively straightforward C with a few external dependencies." In other words, it's easy to port. [...] The only sign that Doom was running in space at first was a lone log entry. So, the team used the satellite's camera to snap real-time images of the Earth, then swapped Doom's Mars skybox for actual satellite photos. "The idea was to take a screenshot from the satellite and use that as the sky, all rendered in software using the game's restricted 256-color palette," explained Waage. Even this posed unexpected difficulties: "Trying to draw all of these beautiful colors with those colors," said Waage, "it's probably not going to work right off. But we tried gradient tests, NASA demo photos. It took quite a bit of tweaking." Eventually, instead of a fantasy Mars as the sky background, they got a good-looking, real Earth in the game's sky. The game itself ran flawlessly. After all, Waage said, "It ran beautifully. It's on Ubuntu."

Dinosaurs Were Thriving Until Asteroid Struck, Research Suggests (theguardian.com) 39

An anonymous reader quotes a report from The Guardian: Dinosaurs would not have become extinct had it not been for a catastrophic asteroid strike, researchers have said, challenging the idea the animals were already in decline. About 66 million years ago, during the late Cretaceous period, a huge space rock crashed into Earth, triggering a mass extinction that wiped out all dinosaurs except birds. However, some experts have argued the dinosaurs were already in decline. Now researchers say the dating of a rock formation in New Mexico throws doubt on that idea, suggesting dinosaurs were thriving until the fateful impact.

Dr Andrew Flynn, the first author of the research at New Mexico State University, said: "I think based on our new study that shows that, at least in North America, they weren't going towards extinction." Writing in the journal Science, Flynn and colleagues report how they dated a unit of rock called the Naashoibito Member in the San Juan basin using two methods. Flynn said the perception that overall dinosaur diversity was falling before the asteroid hit could be a result of there being fewer exposed rocks, and hence fossils, dating to the end of the Cretaceous period than earlier in the epoch. "It looks like, as far as we can tell, there's no reason they should have gone extinct except for [the] asteroid impact," he said.

Overshooting 1.5C Climate Target 'Inevitable': UN Chief (nzherald.co.nz) 78

UN Secretary-General Antonio Guterres says it is now clear that efforts to cap global warming at 1.5C above pre-industrial levels will fail in the short term. AFP: Before next month's COP30 climate summit in Brazil, Guterres said going beyond 1.5C would result in "devastating" yet predictable impacts. "One thing is already clear: we will not be able to contain the global warming below 1.5C in the next few years," Guterres said at the UN's World Meteorological Organisation (WMO) weather and climate agency in Geneva.

"Overshooting is now inevitable. Which means that we're going to have a period, bigger or smaller, with higher or lower intensity, above 1.5C in the years to come." However, if leaders start taking the problem seriously by driving towards net zero greenhouse gas emissions, "the 1.5 still remains -- according to all the scientists I met -- possible before the end of the century."

Global Use of Coal Hit Record High in 2024 (theguardian.com) 180

Coal use hit a record high around the world last year despite efforts to switch to clean energy, imperilling the world's attempts to rein in global heating. From a report: The share of coal in electricity generation dropped as renewable energy surged ahead. But the general increase in power demand meant that more coal was used overall, according to the annual State of Climate Action report, published on Wednesday. The report painted a grim picture of the world's chances of avoiding increasingly severe impacts from the climate crisis. Countries are falling behind the targets they have set for reducing greenhouse gas emissions, which have continued to rise, albeit at a lower rate than before.

Clea Schumer, a research associate at the World Resources Institute thinktank, which led the report, said: "There's no doubt that we are largely doing the right things. We are just not moving fast enough. One of the most concerning findings from our assessment is that for the fifth report in our series in a row, efforts to phase out coal are well off track."

New Delhi Pollution Hits Five-Year High (semafor.com) 16

Air pollution in New Delhi hit a five-year high this week, as Diwali fireworks combined with farming fires to shroud the city in a toxic haze. From a report: The annual spike has become something of a tradition in the megalopolis, with some parts of the city this week recording an air-quality index reading of 1,800 -- 20 times higher than levels the World Health Organization deems healthy. The news points to the challenge facing Indian authorities as they look to combat pollution and cut carbon emissions: The country has made huge progress in deploying renewable energy, but will still need up to $21 trillion in new investments in order to meet its 2070 net-zero target, according to government plans reported by Bloomberg.

France and Spain Call on EU To Uphold 2035 Combustion Engine Ban (bloomberg.com) 128

France and Spain are calling on the European Union to stick with plans to ban combustion engine cars in the bloc after 2035, at odds with German Chancellor Friedrich Merz ahead of a meeting of leaders in Brussels this week. From a report: The European Commission, the bloc's executive branch, is currently reviewing rules designed to accelerate the automotive sector's green transition. Merz has called on the bloc to give up its 2035 deadline to help Germany's troubled car industry.

France and Spain "hope that the upcoming review will preserve the 2035 cap and the environmental ambition of the CO2 emissions trajectory that underpins it," a paper presented to climate ministers in Luxembourg on Tuesday, and seen by Bloomberg says. "This revision should in no way call into question the zero emissions exhaust target in 2035."

Are Supershear Earthquakes Even More Dangerous Than We Thought? (yahoo.com) 4

Long-time Slashdot reader Bruce66423 shared this article from the Los Angeles Times: Scientists have increasingly observed how the rupturing of a fault during an earthquake can be even faster than the speed of another type of damaging seismic wave, theoretically generating energy on the level of a sonic boom. These shock waves — created during "supershear" earthquakes — can worsen how bad the ground shakes both side to side and up and down along an affected fault area, scientists at USC, Caltech and the University of Illinois Urbana-Champaign wrote in a recent opinion article for the journal Seismological Research Letters. Although not everyone agrees that supershear earthquakes are inherently more destructive than other types, the potential implications are massive and need to be accounted for in seismic forecasts, the scientists contend... In just the last 15 years, 14 of 39 large strike-slip earthquakes have exhibited features of supershear ruptures, the opinion article said....

In California, supershear earthquakes would be expected on the straightest of "strike-slip" faults — in which one block of earth slides past another — like the San Andreas... There are a number of communities directly on top of the San Andreas fault. Among them are Coachella, Indio, Cathedral City, Palm Springs, Desert Hot Springs, Banning, Yucaipa, Highland, San Bernardino, Wrightwood, Palmdale, Gorman, Frazier Park, San Juan Bautista, Palo Alto, Portola Valley, Woodside, San Bruno, South San Francisco, Pacifica, Daly City and Bodega Bay.

One earthquake scientist suggests building codes need to be more strict, according to the article.

But it also cites a U.S. Geological Survey research geophysicist who isn't convinced by the new opinion article. "I don't think we know yet whether supershear ruptures really are more destructive."

A Classified Network of SpaceX Satellites Is Emitting a Mysterious Signal (npr.org) 46

A network of classified Starshield satellites built by SpaceX for the U.S. government is transmitting signals on radio frequencies reserved for Earth-to-space commands. According to NPR, it may violate international standards. From the report: Satellites associated with the Starshield satellite network appear to be transmitting to the Earth's surface on frequencies normally used for doing the exact opposite: sending commands from Earth to satellites in space. The use of those frequencies to "downlink" data runs counter to standards set by the International Telecommunication Union, a United Nations agency that seeks to coordinate the use of radio spectrum globally.

Starshield's unusual transmissions have the potential to interfere with other scientific and commercial satellites, warns Scott Tilley, an amateur satellite tracker in Canada who first spotted the signals. "Nearby satellites could receive radio-frequency interference and could perhaps not respond properly to commands -- or ignore commands -- from Earth," he told NPR.

Outside experts agree there's the potential for radio interference. "I think it is definitely happening," said Kevin Gifford, a computer science professor at the University of Colorado, Boulder who specializes in radio interference from spacecraft. But he said the issue of whether the interference is truly disruptive remains unresolved. [...] Tilley says he's detected signals from 170 of the Starshield satellites so far. All appear in the 2025-2110 MHz range, though the precise frequencies of the signals move around.

New ITVX Channel Streams Absolutely Spellbinding Footage of Earth... Forever (theguardian.com) 36

An anonymous reader quotes a report from The Guardian: I realize that, at this point, there are already far too many shows. Every channel, every streaming service is teeming with content demanding your attention, and there are simply too few hours in the day to watch them all. However, with that in mind, may I recommend a new show called Space Live? There's only one episode. The only potential downside is that the episode literally lasts for ever. Actually, that's inaccurate. Space Live isn't a show, it's a channel. It launched on Wednesday morning, tucked away on ITVX, and consists only of live footage of Earth broadcast from the International Space Station. It's beguiling to watch, especially for anyone who didn't realize that a person can be awestruck and bored simultaneously.

It's billed as a world first. ITV has partnered with British space media company Sen to use live 4K footage from its proprietary SpaceTV-1 video camera system, mounted on the International Space Station, giving us three camera views: one of the station's docking ports, a horizon view able to show sunrises and storms, and a camera pointing straight down as the ISS passes across the planet. A tracker in the corner of the screen shows the live location of the ISS, while a real-time AI information feed provides facts about our geography and weather systems.

Of course, if you wanted to be picky, you could argue it isn't exactly new. Nasa's YouTube channel has been streaming live footage from the ISS for years, and uniformly draws an audience of a few thousand. But Space Live is, if nothing else, slightly snazzier. The footage is certainly nicer: at 8.30am on Wednesday, Space Live showed gorgeous images of the sun's glare bouncing off the sea around the Bay of Biscay, while all Nasa could offer was a piece of cloth with the word "Flap" written on it. There's even a soundtrack, a constant, soothing kind of hold music that loops and loops without ever becoming fully annoying. It's an improvement, in other words. And, at least for the first orbit, it is absolutely spellbinding.

Beijing Issues Documents Without Word Format Amid US Tensions (scmp.com) 146

An anonymous reader shares a report: China's expansion of its rare earth export controls appeared to mark another escalation in the US-China trade war last week. But the announcements were also significant in another way: unusually, the documents could not be opened using American word processing software.

For the first time, China's Ministry of Commerce issued a slew of documents that could be directly accessed only through WPS Office -- China's answer to Microsoft Office -- as Beijing continues its tech self-reliance drive. Developed by the Beijing-based software company Kingsoft, WPS Office uses a different coding structure to Microsoft Office, meaning WPS text files cannot be opened directly in Word without conversion. Previously, the ministry primarily released text documents in Microsoft Word format.

Earth's Climate Has Passed Its First Irreversible Tipping Point and Entered a 'New Reality' (404media.co) 167

Climate change has pushed warm-water coral reefs past a point of no return, marking the first time a major climate tipping point has been crossed, according to a report released on Sunday by an international team in advance of the United Nations Climate Change Conference COP30 in Brazil this November. From a report: Tipping points include global ice loss, Amazon rainforest loss, and the possible collapse of vital ocean currents. Once crossed, they will trigger self-perpetuating and irreversible changes that will lead to new and unpredictable climate conditions. But the new report also emphasizes progress on positive tipping points, such as the rapid rollout of green technologies.

"We can now say that we have passed the first major climate tipping point," said Steve Smith, the Tipping Points Research Impact Fellow at the Global Systems Institute and Green Futures Solutions at the University of Exeter, during a media briefing on Tuesday. "But on the plus side," he added, "we've also passed at least one major positive tipping point in the energy system," referring to the maturation of solar and wind power technologies.

The world is entering a "new reality" as global temperatures will inevitably overshoot the goal of staying within 1.5C of pre-industrial averages set by the Paris Climate Agreement in 2015, warns the Global Tipping Points Report 2025, the second iteration of a collaboration focused on key thresholds in Earth's climate system.

Scientists Seek To Turbocharge a Natural Process That Cools the Earth 97

fjo3 shares a report from the Washington Post: Across vast stretches of farmland in southern Brazil, researchers at a carbon removal company are attempting to accelerate a natural process that normally unfolds over thousands or millions of years. The company, Terradot, is spreading tons of volcanic rock crushed into a fine dust over land where soybeans, sugar cane and other crops are grown. As rain percolates through the soil, chemical reactions pull carbon from the air and convert it into bicarbonate ions that eventually wash into the ocean, where the carbon remains stored. The technique, known as "enhanced rock weathering," is emerging as a promising approach to lock away carbon on a massive scale. Some researchers estimate the method has the potential to sequester billions of tons of carbon, helping slow global climate trends. Other major projects are underway across the globe and have collectively raised over a quarter-billion dollars. [...]

Terradot was founded in 2022 at Stanford, growing out of an independent study between James Kanoff, an undergraduate seeking large-scale carbon removal solutions, and Scott Fendorf, an Earth science professor. Terradot ran a pilot project across 250 hectares in Mexico and began operations in Brazil in late 2023. Since then, the company has spread about 100,000 tons of rock over 4,500 hectares. It has signed contracts to remove about 300,000 tons of carbon dioxide and is backed by a who's who of Silicon Valley. It expects to deliver its first carbon removal credit -- representing one metric ton of verified carbon dioxide removed -- by the end of this year and then scale up from there.

China Expands Rare Earth Export Controls To Target Semiconductor, Defense Users (reuters.com) 38

Longtime Slashdot reader hackingbear writes: Following U.S. lawmakers' call on Tuesday for broader bans on the export of chipmaking equipment to China, China dramatically expanded its rare earths export controls on Thursday, adding five new elements, dozens of pieces of refining technology, and extra scrutiny for semiconductor users as Beijing tightens control over the sector ahead of talks between Presidents Donald Trump and Xi Jinping. The new rules expands controls Beijing announced in April that caused shortages around the world, before a series of deals with Europe and the U.S. eased the supply crunch.

China produces over 90% of the world's processed rare earths and rare earth magnets. The 17 rare earth elements are vital materials in products ranging from electric vehicles to aircraft engines and military radars. Foreign companies producing some of the rare earths and related magnets on the list will now also need a Chinese export license if the final product contains or is made with Chinese equipment or material, even if the transaction includes no Chinese companies, mimicking rules the U.S. has implemented to restrict other countries' exports of semiconductor-related products to China.

Developing mining and processing capabilities requires a long-term effort, meaning the United States will be on the back foot for the foreseeable future. The Commerce Ministry also added to its "unreliable entity list" 14 foreign organizations, which are mostly based in the United States, restricting their ability to carry out commercial activities within the world's second-largest economy for carrying out military and technological cooperation with Taiwan, or "made malicious remarks about China, and assisted foreign governments in suppressing Chinese companies," it said in a separate statement, referring to TechInsights, a prominent Canadian tech research firm, and nine of its subsidiaries including Strategy Analytics which were among those blacklisted.

Black Holes Might Hold the Key To a 60-Year Cosmic Mystery 20

alternative_right shares a report from ScienceDaily: Scientists may have finally uncovered the mystery behind ultra-high-energy cosmic rays -- the most powerful particles known in the universe. A team from NTNU suggests that colossal winds from supermassive black holes could be accelerating these particles to unimaginable speeds. These winds, moving at half the speed of light, might not only shape entire galaxies but also fling atomic nuclei across the cosmos with incredible energy. [...]

But what on earth does that mean? The Milky Way is the neighborhood in the universe where you and I live. Our Sun and solar system are part of this galaxy, along with at least 100 billion other stars. "There is a black hole called Sagittarius-A* located right in the centre of the Milky Way. This black hole is currently in a quiet phase where it isn't consuming any stars, as there is not enough matter in the vicinity," [said postdoctoral fellow Enrico Peretti from the Universite Paris Cite]. This contrasts with growing, supermassive, active black holes that consume up to several times the mass of our own Sun each year. "A tiny portion of the material can be pushed away by the force of the black hole before it is pulled in. As a result, around half of these supermassive black holes create winds that move through the universe at up to half the speed of light," Peretti said.

We have known about these gigantic winds for approximately ten years. The winds from these black holes can affect galaxies. By blowing away gases, they can prevent new stars from forming, for example. This is dramatic enough in itself, but Oikonomou and her colleagues looked at something else, much smaller, that these winds could be the cause of." It is possible that these powerful winds accelerate the particles that create the ultra-high-energy radiation," said [lead author Domenik Ehlert].
The findings have been published in the journal Monthly Notices of the Royal Astronomical Society.

Removing 50 Objects from Orbit Would Cut Danger From Space Junk in Half (arstechnica.com) 26

If we could remove the 50 most concerning pieces of space debris in low-Earth orbit, there'd be a 50% reduction in the overall debris-generating potential, reports Ars Technica. That's according to Darren McKnight, lead author of a paper presented Friday at the International Astronautical Congress in Sydney, which calculated the objects most likely to collide with other fragments and create more debris. (Russia and the Soviet Union lead with 34 objects, followed by China with 10, the U.S. with three, Europe with two, and Japan with one.) Even just the top 10 were removed, the debris-generating potential drops by 30%.

"The things left before 2000 are still the majority of the problem," he points out, and "76% of the objects in the top 50 were deposited last century." 88% of the objects are post-mission rocket bodies left behind to hurtle through space. "The bad news is, since January 1, 2024, we've had 26 rocket bodies abandoned in low-Earth orbit that will stay in orbit for more than 25 years," McKnight told Ars... China launched 21 of the 26 hazardous new rocket bodies over the last 21 months, each averaging more than 4 metric tons (8,800 pounds). Two more came from US launchers, one from Russia, one from India, and one from Iran. This trend is likely to continue as China steps up deployment of two megaconstellations — Guowang and Thousand Sails — with thousands of communications satellites in low-Earth orbit.

Launches of these constellations began last year. The Guowang and Thousand Sails satellites are relatively small and likely capable of maneuvering out of the way of space debris, although China has not disclosed their exact capabilities. However, most of the rockets used for Guowang and Thousand Sails launches have left their upper stages in orbit. McKnight said nine upper stages China has abandoned after launching Guowang and Thousand Sails satellites will stay in orbit for more than 25 years, violating the international guidelines.

It will take hundreds of rockets to fully populate China's two major megaconstellations. The prospect of so much new space debris is worrisome, McKnight said. "In the next few years, if they continue the same trend, they're going to leave well over 100 rocket bodies over the 25-year rule if they continue to deploy these constellations," he said. "So, the trend is not good...." Since 2000, China has accumulated more dead rocket mass in long-lived orbits than the rest of the world combined, according to McKnight. "But now we're at a point where it's actually kind of accelerating in the last two years as these constellations are getting deployed."

A deputy head of China's national space agency recently said China is "currently researching" how to remove space debris from orbit, according to the article. ("One of the missions China claims is testing space debris mitigation techniques has docked with multiple spacecraft in orbit, but U.S. officials see it as a military threat. The same basic technologies needed for space debris cleanup — rendezvous and docking systems, robotic arms, and onboard automation — could be used to latch on to an adversary's satellite.")

The School That Replaces Teachers With AI (joincolossus.com) 124

Long-time Slashdot reader theodp writes: CBS News has a TL;DR video report, but Jeremy Stern's earlier epic Class Dismissed [at Collosus.com] offers a deep dive into Alpha School, "the teacherless, homeworkless, K-12 private school in Austin, Texas, where students have been testing in the top 0.1% nationally by self-directing coursework with AI tutoring apps for two hours a day.

Alpha students are incentivized to complete coursework to "mastery-level" (i.e., scoring over 90%) in only two hours via a mix of various material and immaterial rewards, including the right to spend the other four hours of the school day in 'workshops,' learning things like how to run an Airbnb or food truck, manage a brokerage account or Broadway production, or build a business or drone."

Founder MacKenzie Larson's dream that "kids must love school so much they don't want to go on vacation" drew the attention of — and investments of money and time from — mysterious tech billionaire Joe Liemandt, who sent his own kids to Larson's school and now aims to bring the experience to rest of the world. "When GenAI hit in 2022," Liemandt said, "I took a billion dollars out of my software company. I said, 'Okay, we're going to be able to take MacKenzie's 2x in 2 hours groundwork and get it out to a billion kids.' It's going to cost more than that, but I could start to figure it out. It's going to happen. There's going to be a tablet that costs less than $1,000 that is going to teach every kid on this planet everything they need to know in two hours a day and they're going to love it.

"I really do think we can transform education for everybody in the world. So that's my next 20 years. I literally wake up now and I'm like, I'm the luckiest guy in the world. I will work 7 by 24 for the next 20 years to fricking do this. The greatest 20 years of my life are right ahead of me. I don't think I'm going to lose. We're going to win."

Of course, Stern writes at Collosus.com, there will be questions about this model of schooling, but asks: "Suppose that from kindergarten through 12th grade, your child's teachers were, in essence, stacks of machines. Suppose those machines unlocked more of your child's academic potential than you knew was possible, and made them love school. Suppose the schooling they loved involved vision monitoring and personal data capture. Suppose that surveillance architecture enabled them to outperform your wildest expectations on standardized tests, and in turn gave them self-confidence and self-esteem, and made their own innate potential seem limitless.... Suppose poor kids had a reason to believe and a way to show they're just as academically capable as rich kids, and that every student on Earth could test in what we now consider the top 10%. Suppose it allowed them to spend two-thirds of their school day on their own interests and passions. Suppose your child's deep love of school minted a new class of education billionaires.

"If you shrink from such a future, by which principle would you justify stifling it?"

Jeff Bezos Predicts Gigawatt Data Centers in Space Within Two Decades (reuters.com) 64

Jeff Bezos told an audience on Friday that gigawatt-scale data centers will be built in space within the next ten to twenty years. The Amazon founder said these orbital facilities would eventually outperform their terrestrial counterparts because space offers uninterrupted solar power around the clock.

Bezos was speaking in a fireside chat with Ferrari and Stellantis Chairman John Elkann. He said the giant training clusters needed for AI would be better built in space because there are no clouds, rain or weather to interrupt power generation. Bezos predicted that space-based data centers would beat the cost of Earth-based ones within a couple of decades. He described the shift as part of a broader pattern that has already occurred with weather satellites and communication satellites. The next steps would be data centers and then other kinds of manufacturing.

Earth Is Getting Darker, Literally, and Scientists Are Trying To Find Out Why (404media.co) 58

An anonymous reader shares a report: It's not the vibes; Earth is literally getting darker. Scientists have discovered that our planet has been reflecting less light in both hemispheres, with a more pronounced darkening in the Northern hemisphere, according to a study published on Monday in Proceedings of the National Academy of Sciences.

The new trend upends longstanding symmetry in the surface albedo, or reflectivity, of the Northern and Southern hemispheres. In other words, clouds circulate in a way that equalizes hemispheric differences, such as the uneven distribution of land, so that the albedos roughly match -- though nobody knows why. "There are all kinds of things that people have noticed in observations and simulations that tend to suggest that you have this hemispheric symmetry as a kind of fundamental property of the climate system, but nobody's really come up with a theoretical framework or explanation for it," said Norman Loeb, a physical scientist at NASA's Langley Research Center, who led the new study. "It's always been something that we've observed, but we haven't really explained it fully."

To study this mystery, Loeb and his colleagues analyzed 24 years of observations captured since 2000 by the Clouds and the Earth's Radiant Energy System (CERES), a network of instruments placed on several NOAA and NASA satellites. Instead of an explanation for the strange symmetry, the results revealed an emerging asymmetry in hemispheric albedo; though both hemispheres are darkening, the Northern hemisphere shows more pronounced changes which challenges "the hypothesis that hemispheric symmetry in albedo is a fundamental property of Earth," according to the study.

Japan Saw Record Number Treated For Heatstroke in Hottest-Ever Summer (japantimes.co.jp) 39

More than 100,000 people were sent to hospitals due to heatstroke in Japan between May 1 and Sunday, according to preliminary data from the Fire and Disaster Management Agency. Bloomberg, via Japan Times: The number is the most on record, according to NHK. Transport to hospitals of patients linked to heatstroke over the period rose almost 3% to 100,143 from a year earlier as Japan saw its national temperature record broken twice in a matter of days. The country's average temperature during this summer was the highest since the statistic began being compiled in 1898, the nation's weather agency said last month.

Heat waves around the world are being made stronger and more deadly due to human-caused climate change. Government officials in August pledged to boost public health protections and encouraged the installation of more air conditioners in school gymnasiums and the use of cooling centers in communal spaces like libraries. New rules came into effect this summer that require employers to take adequate measures to protect workers from extreme temperatures.

NASA Backs Lunar Wi-Fi Project To Connect Astronauts and Rovers On the Moon (nerds.xyz) 22

BrianFagioli shares a report from NERDS.xyz: NASA has awarded Solstar Space a $150,000 SBIR Phase I contract to develop a Lunar Wi-Fi Access Point (LWIFI-AP). The system is designed to provide wireless connectivity for astronauts, rovers, and orbiting spacecraft as part of the Artemis and Commercial Lunar Payload Services programs. Solstar's goal is to build a space-rated, multi-band, multi-protocol access point that can survive radiation, extreme lunar temperatures, and other harsh conditions. NASA has identified Wi-Fi and 3GPP standards as core communication needs across mission systems ranging from the Human Landing System and Lunar Terrain Vehicle to the Lunar Gateway.

Although this is only an early-stage contract, Solstar's proposal addresses a clear gap in space-qualified networking hardware. The company says that just as Wi-Fi transformed daily life on Earth, it will be equally important for living and working on the Moon. If the project advances, astronauts could soon be relying on familiar wireless technology that has been adapted for one of the most challenging environments in existence.
