Futurism reports: While many scientists have long held that Mars is "geologically dead" inside, new research is adding to the growing body of evidence to the contrary.

As detailed in a new paper published in the journal Science Advances, an international team of researchers examined data collected by the European and Russian ExoMars Trace Gas Orbiter in 2021, which found that Mars is slowly belching hydrogen chloride gas. The researchers suggest this gas is being released from hot magma deep beneath its surface after discovering intriguing new fissures along a massive volcano, indicating the planet may be geologically active after all — or at least it was until relatively recently.

The research could have significant implications for the possibility of ancient life on the Red Planet, hinting at a far warmer and thicker atmosphere — and an abundance of liquid water on its surface — in its not-too-distant past.... The team discovered new fissures measuring thousands of feet in length... suggesting ongoing activity underneath the surface. The researchers discovered discolorations along these fissures, concluding that they may be the result of seeping gases leaving mineral deposits similar to volcanic gas vents on Earth... The fissures could also be a perfect place to find evidence of past life on the Red Planet [argued Daniel Mège, the study's colead author and a Polish Academy of Sciences professor]... "If hydrothermal systems are active, they could contain the ingredients and energy needed for microorganisms to develop, and shield microorganisms from the hostile and changing environment above the surface."

Saturday NASA officials announced it's accepting applications for a new astronaut class, reports the Associated Press: With only 32 active astronauts, the space agency needs more recruits as it looks to expand humanity's presence beyond low-Earth orbit as quickly as possible... "We have far more work than we have astronauts," Artemis III commander Randy Bresnik told The Associated Press on Saturday. Aspiring astronauts have between now and Dec. 3 to submit their applications... [They'll begin their training by early 2028]. By then "we're going to have people on the moon — so don't delay," Bresnik urged potential candidates.

Bresnik and his three crewmates will blast into orbit next summer to practice docking their capsule with a pair of lunar landers, one built by Elon Musk's SpaceX and the other by Jeff Bezos' Blue Origin. Their mission will stick close to Earth — no lunar flyby — and serve as a dress rehearsal for the following year's Artemis IV mission that will attempt to land two astronauts near the lunar south pole. The moon base will materialize as more rovers, robots, structures and power grids are launched.
The article notes NASA's last call for new astronauts was two years ago, and "More than 8,000 applied, with 10 making the final cut in September 2025."

Slashdot reader sandbagger brings news about the classic science ficdtion magazine Starlog. It's 33-year run from 1976 to 2009 is now available on the Internet Archive.

And 17 years after publishing its final issue, Starlog is relaunching, publishing one issue a year starting November 13, according to The Hollywood Reporter: The magazine launched in 1976 and gained a fanbase for being one of the few places to get reliable news and interviews about geek culture. It launched with a cover focusing on Star Trek, one of its key areas of expertise, but the magazine's editors and writers also pioneered coverage of Star Wars. (The new issue chronicles some of the rumors it put out a year before the movie opened). In all, Starlog published 374 issues and more than 25,000 pages... In addition to the film and TV-focused features Starlog was known for, the new Starlog will also delve into futurism, as the cover from Gabriel Yeganyan highlights. The opening story of issue No. 1 looks at the viability of humans farming crops on planets outside of Earth, for example... The revival was announced earlier this year, and includes a podcast hosted by Jordan Hoffman, a veteran journalist who has contributed to The Hollywood Reporter.

"I didn't think a rock like this existed on Earth," a geologist at the Lunar and Planetary Institute in Texas told the Washington Post. It looks like a polished rock, dark brown with a clay-colored stripe — but it's actually one of the oldest Mars meteorites ever found, blasted by an impact from the surface of Mars billions of years ago: Technically speaking it's a collection of eight rock fragments, the largest of which is about the size of a fist. Nearly two pounds of the meteorite was discovered in the Sahara in Mali in 2022, and most is now held by a museum in Maine. Within two years, an initial examination determined the meteorite hailed from Mars; scientists are now finally digging deeper, with stunning results.
It offers records of "interactions of water and rock and maybe even an imprint of the Martian atmosphere as it was losing water," says Lee Saper, co-author of a new paper recently published in Science. "It was only after we started looking closely that we realized this meteorite is really unique," said Yang Liu of NASA's Jet Propulsion Laboratory in Southern California, the lead author of a new paper published in Science. "One of the paper's reviewers called it a Rosetta Stone for Mars."

Its mix of minerals "tells a story about how the planet's crust formed from cooling magma before it was eventually altered by subsurface water," NASA's JPL says in an announcement. The Washington Post reports: The story begins 4.1 billion years ago, when crystals of a mineral called zircon probably solidified out of molten magma on Mars. "That was a game changer," [said Yang Liu, a planetary scientist at NASA's Jet Propulsion Laboratory in California], since scientists can date zircon very precisely, and it has been rare in other Mars meteorites. The date immediately put the Teghaza meteorite on special footing, alongside only two other Mars rocks known to have formed by 4 billion years ago...

Perhaps most intriguingly, the researchers also saw signs that the rock had been exposed to water during its evolution, a find detailed in work published this summer in Science Advances.

Blue Origin has unveiled a third stage called GS3 for its New Glenn rocket, designed to deliver satellite constellations directly to geostationary orbit and support heavy-lift missions to the Moon and deep space. The company also announced Northstar, a new methalox booster engine that it says produces 715,000 pounds of thrust while cutting mass by 30% and parts by 50% compared with the BE-4. Space.com reports: The new stage will be powered by one BE-7 engine, which the company developed for use on its Blue Moon spacecraft, one of the two private vehicles that NASA selected to be crewed lunar landers for its Artemis program. (The other is SpaceX's Starship.) Blue Moon landing missions won't need to launch on GS3-equipped New Glenn rockets, according to Blue Origin. But the third stage "can support sustained operations around the moon," the company wrote in today's blog post. "By delivering significant payload mass directly to trans-lunar injection (TLI), GS3 enables faster transit times while preserving propellant for on-orbit operations." And there's already demand for such services: Blue Origin also announced today that a government customer (which it did not name) has booked a GS3 mission to cislunar (Earth-moon) space, with launch targeted for 2028.

And the company dropped yet more news today -- that it's working on a new first-stage engine, called Northstar. Like Blue Origin's other booster engine, the BE-4, Northstar burns liquid oxygen and liquid methane propellant, a combination known as methalox. But the new engine is more powerful and less complex. "Compared to the BE-4 engine, Northstar reduces mass by 30% and parts count by 50%, while increasing thrust from 640,000 to 715,000 pounds-force," Blue Origin said in a second blog post today. "Manufacturing advancements have also significantly shortened production timelines, enabling assembly in less than a day." Northstar went from program approval to development testing in just 11 months, according to the company. But today's update did not say when the new engine will fly for the first time.

An anonymous reader quotes a report from Scientific American: The Great Pacific Garbage Patch, an area in the Pacific Ocean where debris naturally accumulates, is full of tiny bits of plastic -- so full, in fact, that it seems to be changing the color of the ocean. [...] To better understand how microplastics may have influenced the ocean's color, [Daniel Koestner, a postdoctoral fellow at the University of Bergen in Norway] and his colleagues looked at 20 years of satellite data from the spot in the ocean with perhaps the most of plastic -- the Great Pacific Garbage Patch, a zone between Hawaii and California where trash trapped by ocean currents accumulates.

Between 2002 and 2022, the researchers found, waters near the garbage patch have gotten brighter in both blue and green wavelengths compared with surrounding areas. The results, published in the journal Communications Earth & Environment on Thursday, don't yet prove that microplastics have directly brightened the ocean, the researchers emphasize, though their findings are backed up by lab experiments with microplastics. But without taking direct ocean samples, it's hard to know for sure what's causing the ocean's color to change. "We're still one step away from proving definitively that microplastics are causing the shift in color that that we're seeing," adds study co-author Shea Cheatham, a Ph.D. student also at the University of Bergen. "We just have to get in there [to the garbage patch] to verify."

The hope is that detecting these color shifts could help identify other areas around the world where microplastics have accumulated.

AMD expects its fourth-quarter revenue to reach roughly $17 billion, potentially surpassing Intel's projected $15 billion to $16 billion and putting AMD ahead of its longtime rival in quarterly sales for the first time. The milestone is being driven largely by booming demand for Epyc server processors and Instinct AI accelerators, with AMD's data center business already accounting for 64% of revenue and expected to exceed 80% in 2027. Tom's Hardware reports: For those of our readers who have been following the CPU market in general as well as AMD and Intel in particular for decades, arguably the most earth-shattering part of AMD's earnings report is its outlook for the fourth quarter. The company expects revenue of approximately $17 billion, plus or minus 3%, which implies a 66% year-over-year increase and 27% sequential growth at the midpoint. In contrast, Intel expects fourth-quarter revenue of $15 billion to $16 billion amid weakening PC demand and manufacturing capacity constraints.

If AMD meets its guidance, its quarterly sales will surpass those of its considerably bigger rival Intel for the first time in history. In fact, AMD will not only leave Intel formally behind, but its projected advantage will be approximately $1.5 billion at the midpoint of both companies' forecasts, which is a tangible lead. The development reflects the companies' increasingly different positions on the market: AMD is rapidly expanding its data center CPU and AI accelerator businesses, while Intel continues to depend heavily on PC and enterprise server processors, which sales face headwinds due to high memory prices and components shortages.

joshuark shares a report from Wired: After 22 years in orbit and a failed rescue mission this summer, it is highly likely that the Neil Gehrels Swift Observatory will crash into Earth sometime next week. It is not known where on the planet the spacecraft -- which is roughly as big as a large elevator -- will fall. Despite its size, experts say the risk to the public is relatively low. The observatory was designed to operate for a few years in low Earth orbit, but it far exceeded its expected lifespan, helping to make many important discoveries about the evolution of the cosmos, including the study of supernovas and the destruction of stars by black holes. However, in 2024, increased solar activity heated and expanded the upper layers of Earth's atmosphere, increasing the drag on the satellite and accelerating its descent. Without a propulsion system capable of correcting its orbit, its days were numbered. The U.S. Space Force now expects Swift to reenter Earth's atmosphere around November 6. Most of the spacecraft is expected to burn up, although some components could survive and reach the ground (but most likely the ocean).

"The most likely survivors are its six heavy reaction wheels, the spinning flywheels it used to aim itself, along with tougher telescope parts such as lenses and mirrors," Dean Sladen, a quality manager and aerospace engineer at Accu Components, told Space.com. "Only a handful of small, scorched fragments are expected to make it down -- nothing recognizable as a telescope."

"NASA's own orbital debris requirements state that the risk of human casualty from surviving debris shall not exceed one in 10,000, so it is highly likely this work has been completed but not published," Sladen said regarding the risk assessment. "Personally, I believe it should be published, as NASA has done with previous satellites. The risk is almost certainly very small, but it would give people a clear, factual picture rather than guesswork."

At the Seventh Manned Spaceflight Conference in Beijing, Chinese space officials publicly outlined the most detailed roadmap yet for landing astronauts on the Moon "before 2030." Ars Technica reports: China's lunar landings will involve a lunar-orbit rendezvous similar to what NASA did in the 1960s and early 1970s with the Apollo program. However, lacking a rocket as powerful as the Saturn V vehicle, the crew and lunar lander will launch separately to the Moon. According to slides shared on social media, the current plan involves:

- An uncrewed test of the Long March 10A rocket (a single-stick variant, with no boosters) and the Mengzhou spacecraft to low-Earth orbit. Target: early 2027
- An uncrewed test of the larger Long March 10 rocket (a core stage with two boosters) and the Lanyue lunar lander, including descent/ascent from Moon's surface. Target: 2028
- A concurrent launch of two Long March 10 rockets, one carrying uncrewed Mengzhou and the other the Lanyue vehicle; they will dock in lunar orbit. Target: 2029
- Dual launch of Long March 10 rockets, this time with crew on the Mengzhou spacecraft, leading to crewed landing mission. Target: "Before 2030"

The public release of this new information provides a timeline for gauging China's technical progress in its efforts to land humans on the Moon before 2030 and beat NASA and the United States back to the lunar surface. Notably, the plan (for now, at least) omits a mission similar to Apollo 8 or Artemis II, which involved a crew flying out to the Moon and either entering orbit or passing close by before returning to Earth. The Mengzhou vehicle should still get a workout closer to Earth with humans on board as part of missions carrying astronauts to Tiangong, China's space station in low-Earth orbit.

CNN reports: The popular theory that comets were crucial in kick-starting life on Earth billions of years ago may not hold up, according to new computer simulations that counter decades of scientific thinking. The finding suggests the fragile organic molecules supposedly carried by the icy objects would have been destroyed on impact, upending an established origin of life theory that dates back to at least 1961 [with earlier versions postulated in 1908]...

Early in its history — over 4 billion years ago — Earth may have experienced a period of heavy bombardment from more than 100,000 comets larger than 100 meters (328 feet), according to the new study, published Wednesday in the journal Scientific Reports. Those impacts, however, were mostly too heavy for life-starting molecules to withstand. The team used the latest models of comet formation and evolution to simulate this early planetary period 100,000 times. "Given what we know about surface environments on the early Earth, on average, our simulations found that there were no successful impacts," said lead study author Richard Anslow, who conducted the research while completing his doctorate at the Institute of Astronomy of the University of Cambridge in the United Kingdom... "The typical velocities of these comets when they impact the Earth meant that actually very few, if any, would have been able to deliver intact organic molecules, so comets actually don't seem to be as useful for prebiotic chemistry as was previously thought," Anslow said.

More precisely, 54% of the simulations showed no impact at all, while the remaining 46% had at least one and a "tiny minority" returned up to three collisions, Anslow said. "We can't rule out confidently that there was never a successful impact — there could have been one of these fluke impacts." However, such flukes had to occur in a "perfect location" that already met several important conditions, including the presence of liquid water and other chemicals needed to support life. That combination makes the overall process unlikely, he added.
The article notes his argument that even if a successful impact occurred, it's unlikely an important chemical like hydrogen cyanide (HCN) could survive the impact, and would've dissolved in an ocean impact. Plus, "many other precursor molecules are also needed, such as compounds that contain phosphorus and sulfur, but these are not routinely found in comets, Anslow said." An alternative cosmic source of organic material could have been asteroids, which typically struck Earth more slowly and in greater numbers. Anslow pointed to recent findings on samples from asteroids Bennu and Ryugu, which contain the majority of protein-building amino acids. The recent study also raises another intriguing possibility: While Earth may not have had the ideal conditions to foster HCN from comet impacts, ancient Mars might have been better suited. "Because Mars is much smaller than Earth and further away from the sun, the typical impact velocity of comets is much lower, so while these impacts on Earth were destroying most of the HCN, this wasn't the case so much for Mars," Anslow said. This idea could add another dimension to the long-standing question of whether the red planet once supported life.

While the authors closely analyzed how HCN could have survived comet impact, the chemical may have undergone reactions before the icy bodies entered Earth's atmosphere, said Queenie Chan, an associate professor of Earth sciences at Royal Holloway University of London, who was not involved with the study. This process could have created biologically important compounds, such as those protein building blocks, that are less volatile and more likely to survive.

The FCC has approved (PDF) Amazon Leo's $11.5 billion acquisition of satellite operator Globalstar, giving the Starlink rival additional infrastructure and spectrum to expand into direct-to-device satellite connectivity. Engadget reports: You may not know Globalstar but have possibly used its services, as the company provides Apple's emergency satellite connectivity for compatible iPhones and Watches. Interestingly, Apple also held a 20 percent stake in Globalstar prior to its takeover. As part of the deal, Leo will power satellite services for supported iPhone and Apple Watch models.

Leo, a rival to SpaceX's Starlink, has been active of late. The company recently announced that it has 400 satellites in orbit and revealed last month that it had launched high-quality satellite internet service in Uzbekistan. It's teaming up with Delta to eventually bring satellite internet to flights, as well. Amazon recently added six new Arianespace launches and aims to have more than 3,000 low-earth orbit satellites up in the near future, still well short of SpaceX's 11,000 satellites.

Astronomers using the Vera C. Rubin Observatory have discovered 2026 ED138, a large object beyond Neptune that could become the solar system's sixth recognized dwarf planet if further observations confirm it is massive enough to be round. Located about 46 times farther from the Sun than Earth, the object is estimated to be 600 to 1,500 kilometers wide and had remained hidden because it lies against a particularly crowded field of Milky Way stars. Scientific American reports: The discovery was made by running billions of pieces of data collected by the Rubin Observatory through a search code developed by Center for Astrophysics | Harvard & Smithsonian astronomers Matthew Holman and Kevin Napier. "My first reaction was one of excited disbelief," Holman said in a statement. "Objects like this are very rare, so I immediately started checking whether I or the code had done something wrong."

When Holman and his colleague Mario Juric of the University of Washington went to double-check, they found 30 more observations of the object by Rubin that dated to between March and July 2026. Looking at other observation tools, the pair found even more sightings going back to 2016. Together, these data allowed the astronomers to begin mapping out 2026 ED138's orbit. The suspected dwarf planet is about 46 times as far from the sun as Earth, making it even more remote than Pluto, which is just 40 times as far. The object is also tilted off the solar system's plane by around 25 degrees, an arrangement that could be linked to disruptions caused by Neptune's gravitational pull.

Initial measurements indicate that 2026 ED138 has a diameter between 600 and 1,500 kilometers (373 and 932 miles), which makes it one of the largest dwarf planet candidates yet detected. But size isn't all that matters: further observations are required to determine if the object has enough mass to be pulled into a round shape, which is a key requirement for a dwarf planet. Despite its size, 2026 ED138 was able to avoid detection for all these years because it's located in a part of the night sky that's crowded with stars whose light drowned it out.

Ars Technica's Dan Goodin reports: Defenders across the world face the burden of responding to yet another botched code-execution vulnerability, this time in boot-time firmware used by most of the world's server vendors and data centers. The vulnerability, with a severity rating of 9.5 out of 10, resides in the TianoCore EDK II, an open source codebase that hardware makers and cloud providers use to create the UEFI firmware that runs during the boot-up sequence. Last year, a representative of the UEFI Forum called (PDF) EDK2 the "preeminent solution / implementation of the UEFI specifications." Virtually all UEFI suppliers (sometimes still called IBVs or independent BIOS vendors), including AMI, Insyde, and Phoenix, use the reference code extensively. Project Mu, Microsoft's hardened EDK2 fork, used the code containing the vulnerable component as well.

The vulnerability, tracked as CVE-2026-97631, is a memory-corruption flaw in an ICMP component that attackers can exploit to execute malicious code that runs before the operating system and firmware can implement defenses like Secure Boot, which establishes a chain of trust for all code, including the Trusted Platform Module (TPM), loaded during boot. While final payloads delivered by CVE-2026-97631 have no persistence -- meaning they run only once -- they can give attackers a wide opening to install other payloads that also run each time early in the boot process.

The parties that discovered CVE-2026-97631 -- Alex Matrosov of Anthropic and Dan Holmes of Google -- had arranged for it to stay under wraps until a coordinated disclosure that was scheduled for January. AMI, a maker of motherboards and other hardware, published this pull request last month that detailed the vulnerability and included a code fix. Once the post came to the attention of the discovering parties, TianoCore Project members published a public advisory last week. With publicly available patch code, it will be trivial for advanced hackers to learn how the vulnerability is triggered and to build working exploits. Further compounding the urgency, patching UEFI code vulnerabilities in millions of end devices sold and used by thousands of hardware makers and cloud providers is cumbersome and time-consuming.

NASA is accelerating its Artemis program with an Apollo-era sense of urgency, aiming to return astronauts to the lunar surface in 2028 and establish a permanent base near the moon's south pole. The Associated Press reports: Administrator Jared Isaacman said Friday that the space agency is still on track to launch Artemis III next summer on a docking exercise with Elon Musk's and Jeff Bezos' lunar landers. The two-week mission featuring four astronauts will be confined to orbit around Earth -- no moon trip this time. The all-important Artemis IV -- NASA's first moon landing by astronauts since Apollo -- remains scheduled for 2028, Isaacman said. His update came six months after the successful Artemis II flight around the moon by four astronauts, humanity's first lunar trip in more than half a century.

NASA will keep its options open as long as possible before choosing between SpaceX and Blue Origin for the Artemis IV lunar lander, according to officials. Isaacman said the "new space race" to land astronauts on the moon -- racing against China now versus the Soviet Union during the Apollo era -- will be "much closer than it ever needed to be" because of slow going in past years. But the space agency is now accelerating its pace, he noted, eliminating endless meetings and bureaucratic inertia, as SpaceX, Blue Origin and other companies scramble around the clock to meet the deadlines and NASA bolsters its workforce.

Adopting Apollo's urgent and intense approach from 1968 through 1972, a period which saw 24 astronauts fly to the moon and 12 land on it, is not "tech industry pixie dust or some new management philosophy," Isaacman said. "It's about our own history. It's a playbook this agency knows really well, the same playbook that went from Apollo 7 splashdown to Apollo 11 in just nine months," he said during a news conference at Kennedy Space Center.

Longtime Slashdot reader schwit1 shares a report from TWZ: A Russian satellite, Kosmos 2612, may have passed within approximately 85 feet (26 meters) of a U.S.-registered satellite belonging to commercial imagery provider ICEYE. This would be an extraordinarily close and potentially dangerous pass-by for two objects in space traveling at thousands of miles per hour. For weeks beforehand, ICEYE-X36, which would be of special interest to Russia, had already found itself in increasingly close orbital alignment with its pursuer. The two satellites now look to be drifting further and further apart, but the episode has been a clear sign of what is to come as the potential for conflict in space only continues to grow.

Publicly available space tracking data from the satellitemap.space and orbitalradar.com websites show that Kosmos 2612 (also written sometimes Cosmos 2612 and abbreviated K2612) and ICEYE X36 had their especially close encounter at approximately 16:07 UTC today. Private space services company LeoLabs also told TWZ today that it could not "confirm or contradict what other data sources have stated publicly," but that it has "high-confidence that the objects came within approximately [emphasis in the original] 500 meters [1,640 feet] of each other." Kosmos 2612 had been making progressively closer passes by ICEYE X36 in recent days. "This is the most advanced and potentially dangerous uncooperative RPO we've observed," Adam Marsh, LeoLabs vice president for technical solutions, separately told Breaking Defense.

"It's important to note that 'red' on 'blue' engagements, such as this, are relatively uncommon in Low Earth Orbit (LEO)," LeoLabs' report points out. At the same time, "this was not a routine conjunction or 'fly by.' The sequence included a controlled approach, changes in relative position, close-proximity loitering, additional small maneuvers, and a controlled departure. The behavior is consistent with sophisticated rendezvous and proximity operations (RPO)."

"We can only speculate about the operation's goal, but it could have been anything from simply intimidation to outright destruction or sabotage of a U.S.-registered satellite," CSIS' Clayton Swope told TWZ. "Perhaps the operation is on hold. There are, however, several other satellites that shadowed ICEYE X36 back in May that could be brought in[to] action too."

Japan has successfully launched its Martian Moons eXploration (MMX) mission to study Mars' two moons, Phobos and Deimos. Scheduled to arrive in August 2027, "MMX will become the first spacecraft to land on and return samples from Phobos for study back on Earth, which scientists think could shed light on a decades-old mystery about the moons' origins" and resolve whether they were formed from a giant impact or were captured asteroids, reports Space.com. From the report: It was the 10th liftoff of Japan's expendable, two-stage H3 rocket, which was jointly developed by JAXA and Mitsubishi Heavy Industries. After clearing its launch pad today, the 207-foot-tall (63 meters) launch vehicle flew a nominal trajectory through its ascent corridor over the Pacific Ocean, jettisoning its four solid boosters in pairs just before the flight clock reached two minutes. The rocket shed its payload fairings about one minute and 20 seconds later, exposing MMX to the vacuum of space for the first time. [...] MMX is now under its own power, and on course for Mars.

The interplanetary transit will last about 10 months, with the spacecraft scheduled to arrive at the Red Planet in August 2027. When it does, MMX's propulsion module will execute an orbital insertion burn to place itself in a quasi-satellite orbit (QSO) around Phobos, which places MMX within the space around the moon as both circle Mars. MMX will spend about three years in the Martian system, devoting much of that time to studying the 14-mile-wide (22 km) Phobos with its science instruments. The spacecraft also carries the IDEFIX rover, a joint effort of the space agencies of France and Germany, which is scheduled to deploy to the surface of Phobos in late 2028 or early 2029.

After a mapping campaign to select suitable landing sites, MMX will perform two separate touchdowns on Phobos to collect and stow samples in the spacecraft's return capsule. Following its second landing and sample collection, MMX will briefly return to QSO with Phobos before transferring to a more elongated orbit around Mars that intersects with the planet's smaller moon, Deimos, which is just 8 miles (14 km) in diameter. During the last several months of its time around Mars, MMX will perform a series of Deimos flybys before departing for Earth in November 2030. If all goes according to plan, the MMX sample-return capsule will land in Australia in 2031. You can watch a recording of the launch on YouTube.

"Jeff Bezos' Blue Origin said Friday it plans to make extensive upgrades to its Florida launch facilities," reports CNBC, "with the goal of supporting multiple flights per week by the end of the decade."

"The company will add two more launch and landing pads for New Glenn, its heavy-lift, partially reusable rocket." A $330 million expansion to its Rocket Park campus in Cape Canaveral, expected to be complete in the summer of 2027, will enable it to produce up to 150 upper stages of its New Glenn rocket annually, Blue Origin said in a blog post. "These investments are centered on one goal: building the capacity to support more missions, more reliably, and more efficiently," Ian Richardson, Blue Origin's senior vice president of operations, wrote in the post. "As we look ahead, this infrastructure is designed to support multiple flights per week by the end of the decade...."

Blue Origin said it's building a new customer integration facility with the U.S. Space Force at Cape Canaveral Space Force Station that will enable it to "prepare multiple missions at once" when it's up and running. Blue Origin has invested more than $3 billion in its infrastructure and facilities in Florida, which now spans more than 20 sites across the state's Brevard and Orange counties, with more than 5,000 employees, [Ian Richardson, Blue Origin's senior vice president of operations, wrote in the blog post].
The article notes it's part of "a flurry of investment" as SpaceX stops offering commercial rides on its Falcon 9, "with $92.5 billion invested in the commercial space sector in the first three quarters of 2026, according to a report this week by venture capital firm Space Capital." And it happens as Blue Origin, SpaceX and other rocket providers "are seeing increasing demand from companies and governments trying to deploy satellites into orbit."

"Launching at a high cadence requires a connected system," says Blue Origin's blog post, "one that manufactures vehicles at scale, prepares customer payloads efficiently, supports reliable launch operations, and quickly returns reusable boosters to service. We are building that system here in Florida," and "laying the foundation for a future where access to space is more frequent, more reliable, and more affordable, for the benefit of Earth."

Astronomers have identified what may be the first genuinely green star, a white dwarf called WD J1330+6435 located about 326 light-years from Earth. Space.com reports: The researchers found that some dead star white dwarfs can go a little green around the gills after snacking on orbiting planets. An example of this is WD J1330+6435, a cool white dwarf located around 326 light-years away, which has been accreting rocky material from a planetary companion. This has enriched its atmosphere with calcium, lithium, and sodium, and the team's model suggests this would have led WD J1330+6435 to adopt a green hue.

[...] The researchers think that no other star, living or dead, has ever been credibly reported as green. That makes WD J1330+6435 the first known genuinely green star. "The traces of sodium in the atmosphere of this white dwarf absorb the orange part of the spectrum, leaving behind a ghostly green glow," Hollands said. "Imagine standing on a planet and looking up at a green star. It feels like something out of science fiction." The researchers also discovered what may be the reddest star ever observed, the white dwarf WD J1011+2845, located just 48 light-years away.

The findings have been published in the journal RAS Techniques and Instruments.

Timekeepers have officially voted to eliminate the leap second, allowing Coordinated Universal Time to drift as much as one hour from Earth's rotation before a correction is needed. The change ends decades of occasionally adding or subtracting seconds and replaces it with a hypothetical "leap hour" that likely wouldn't be necessary for hundreds or even thousands of years. Smithsonian Magazine reports: "It's kind of a philosophical discussion, because if a leap hour happens, it won't be for a very, very long time," Christian Bizouard, director of the IERS Earth Orientation Center in France, tells the Guardian's Ian Sample. "What we are doing is pushing back the decision."

The move caps off 30 years of debate, as the leap second has been highly controversial in the world of timekeeping. Leap seconds aren't nearly as smooth of a fix as leap years are, and they can cause computer and website issues. Reddit famously crashed when a leap second was added on June 30, 2012. It's "always been a problem," Judah Levine, a former researcher at the NIST's Time and Frequency Division, tells Scientific American's Emma Gometz.

Instead of adding the entire second all at once, companies such as Google and Meta add the extra time in smaller segments in a tactic called "smearing," according to the Conversation. It's not a simple task, however, and companies that employ smearing have long lobbied to get rid of the leap second. What's more, with Earth's recent spin acceleration, timekeepers around the world were facing the possibility of the world's first negative leap second, in which a second would be subtracted from UTC. This sparked fears, akin to those surrounding Y2K, that our modern technologies wouldn't be able to handle such a change.

"It's never happened before, and therefore the software for that has never been tested," Darryl Veitch, a researcher who leads the Timing Lab at the University of Technology Sydney, tells the Australian Broadcasting Corporation's Ellen Phiddian. But others argued that it wouldn't be much of a problem. The vote means that in the future, UTC will be allowed to diverge from astronomical time more than ever before.

Researchers from Mount Sinai, NASA, and Space Tango have launched miniature human hearts and brains to the International Space Station to study how microgravity and radiation affect organs and potentially accelerate aging. "If people are going to be living and working in space, then we need to understand what's going to happen to them," David Sachs, assistant professor of surgery at the Icahn School of Medicine at Mount Sinai, told ABC News. "But also, because it's interesting as a model of accelerated aging for studying people on Earth." From the report: The mini organs launched aboard commercial resupply mission CRS-35 on Tuesday morning from Cape Canaveral Space Force Station in Florida. They are expected to arrive at the International Space Station (ISS) on Thursday. The miniature organs offer researchers a unique opportunity to simulate aging in a much shorter period of time to understand disease and develop treatments. "Six months in space ... is equivalent to about 10 to 20 years of aging on Earth," Kevin Costa, associate professor of surgery at the Icahn School of Medicine at Mount Sinai, told ABC News.

Sachs and Costa are sending up to 16 miniature hearts to the ISS to test how they respond to electrical signals and monitor how they may react to near-zero gravity. The technology, which is integrated into a miniature laboratory called CubeLab, was developed by Space Tango and simulates the natural environment in the human body. "[It is] slightly bigger than a shoebox, and it is a fully automated, miniaturized system," Gentry Barnett, chief technology officer at Space Tango, told ABC News.

[...] As part of the new effort, the team is sending miniature brains, called miBrain, to the ISS. Around the size of a peppercorn, the miBrains reflect models of healthy and diseased brains. By exposing them to the space environment, scientists can see how mini-brains respond and better understand why living in space accelerates aging. Though the mini organs are not full-sized human organs, the researchers say they are good substitutes, cost-effective and don't take up much of the limited space aboard the space station. They also believe discoveries made in space can translate to uses in everyday medical care.

The microgravity environment uniquely allows researchers to study what happens to humans with a sedentary lifestyle or prolonged bed rest, which isn't easily simulated on Earth, Sachs explained. "[The research is] translating to stuff in space, but it's also translating back to the research we do in the laboratory to help people with Parkinson's and Alzheimer's disease," Joel Blanchard, associate professor of stem cell biology and regenerative medicine and neuroscience at the Icahn School of Medicine at Mount Sinai, told ABC News. Lisa Carnell, the director of the biological and physical sciences division at NASA, told ABC News that these experiments serve as a starting point for future research beyond low Earth orbit, including to the moon and beyond.
