After Seven Years, Sample Collected From Asteroid Finally Returns to Earth (nasa.gov) 34

OSIRIS-REx weighs 4,650 pounds (or 2,110 kg). On September 8th of 2016, NASA first launched the spacecraft on its 3.8-billion mile mission to land on an asteroid and retrieve a sample.

That sample has just returned.

Throughout Sunday morning, NASA tweeted historic updates from the sample's landing site in Utah. "We've spotted the #OSIRISREx capsule on the ground," they announced about 80 minutes ago (including a 23-second video clip). "The parachute has separated, and the helicopters are arriving at the site. We're ready to recover that sample!"

UPI notes that the capsule "reached temperatures up to 5,000 degrees Fahrenheit during reentry, so protective masks and gloves are required to handle it," describing its payload as "a 250-gram dust sample."

15 minutes later NASA shared footage of "the first persons to come into contact with this hardware since it was on the other side of the solar system." A recovery team approached the capsule to perform an environmental safety sweep confirming there were no hazardous gas.

"The impossible became possible," NASA administrator Bill Nelson said in a statement. The Guardian reports he confirmed the capsule "brought something extraordinary — the largest asteroid sample ever received on Earth.

"It's going to help scientists investigate planet formation, it's going to improve our understanding of the asteroids that could possibly impact the earth and it will deepen our understanding of the origin of our solar system and its formation."

"This mission proves that NASA does big things, things that have inspired us, things that unite us...

"The mission continues with incredible science and analysis to come. But I want to thank you all, for everybody that made this Osiris-Rex mission possible."

Professor Neil Bowles of the University of Oxford, one of the scientists who will study the sample, told the Guardian that he was excited to see the sample heading to the clean room at Johnson Space Center. "So much new science to come!"

And that 4,650-pound spacecraft is still hurtling through space. 20 minutes after delivering its sample, the craft " fired its engines to divert past Earth toward its new mission to asteroid Apophis," NASA reports. The name of its new mission? OSIRIS-APEX. Roughly 1,000 feet wide, Apophis will come within 20,000 miles of Earth — less than one-tenth the distance between Earth and the Moon — in 2029. OSIRIS-APEX is scheduled to enter orbit of Apophis soon after the asteroid's close approach of Earth to see how the encounter affected the asteroid's orbit, spin rate, and surface.

China's Quest for Human Genetic Data Spurs Fears of a DNA Arms Race (adn.com) 32

In 2020 Serbian scientists were gifted China's "Fire-Eye" labs, remembers the Washington Post. The sophisticated portable labs "excelled not only at cracking the genetic code for viruses, but also for humans, with machines that can decipher genetic instructions contained within the cells of every person on Earth, according to its Chinese inventors."

Although some of them were temporary, "scores" of the portable labs "were donated or sold to foreign countries during the pandemic," reports the Washington Post. But it adds that now those same labs "are attracting the attention of Western intelligence agencies amid growing unease about China's intentions." Some analysts perceive China's largesse as part of a global attempt to tap into new sources of highly valuable human DNA data in countries around the world. That collection effort, underway for more than a decade, has included the acquisition of U.S. genetics companies as well as sophisticated hacking operations, U.S. and Western intelligence officials say. But more recently, it received an unexpected boost from the coronavirus pandemic, which created opportunities for Chinese companies and institutes to distribute gene-sequencing machines and build partnerships for genetic research in places where Beijing previously had little or no access, the officials said. Amid the pandemic, Fire-Eye labs would proliferate quickly, spreading to four continents and more than 20 countries, from Canada and Latvia to Saudi Arabia, and from Ethiopia and South Africa to Australia. Several, like the one in Belgrade, now function as permanent genetic-testing centers...

BGI Group, the Shenzhen-based company that makes Fire-Eye labs, said it has no access to genetic information collected by the lab it helped create in Serbia. But U.S. officials note that BGI was picked by Beijing to build and operate the China National GeneBank, a vast and growing government-owned repository that now includes genetic data drawn from millions of people around the world. The Pentagon last year officially listed BGI as one of several "Chinese military companies" operating in the United States, and a 2021 U.S. intelligence assessment linked the company to the Beijing-directed global effort to obtain even more human DNA, including from the United States. The U.S. government also has blacklisted Chinese subsidiaries of BGI for allegedly helping analyze genetic material gathered inside China to assist government crackdowns on the country's ethnic and religious minorities...

Beijing's drive to sweep up DNA from across the planet has occasionally stirred controversy, particularly after a 2021 Reuters series about aspects of the project. Chinese academics and military scientists have also attracted attention by debating the feasibility of creating biological weapons that might someday target populations based on their genes. Genetic-based weapons are regarded by experts as a distant prospect, at best, and some of the discussion appears to have been prompted by official paranoia about whether the United States and other countries are exploring such weapons.

U.S. intelligence officials believe China's global effort is mostly about beating the West economically, not militarily. There is no public evidence that Chinese companies have used foreign DNA for reasons other than scientific research. China has announced plans to become the world's leader in biotechnology by 2035, and it regards genetic information — sometimes called "the new gold" — as a crucial ingredient in a scientific revolution that could produce thousands of new drugs and cures...

U.S. intelligence officials said in interviews that they have limited insight into how BGI handles DNA information acquired overseas, including whether genetic data from the Fire-Eye labs ultimately end up in the computers of China's military or intelligence services... Chinese law makes clear that any information collected using BGI's machines can be accessed by the Chinese government. A national intelligence law enacted in 2017 stipulates that Chinese firms and citizens are legally bound to share proprietary information acquired in foreign countries whenever requested.

NASA's Webb Finds Carbon Source on Surface of Jupiter's Moon Europa 26

NASA, in a press release: Jupiter's moon Europa is one of a handful of worlds in our solar system that could potentially harbor conditions suitable for life. Previous research has shown that beneath its water-ice crust lies a salty ocean of liquid water with a rocky seafloor. However, planetary scientists had not confirmed if that ocean contained the chemicals needed for life, particularly carbon. Astronomers using data from NASA's James Webb Space Telescope have identified carbon dioxide in a specific region on the icy surface of Europa.

Analysis indicates that this carbon likely originated in the subsurface ocean and was not delivered by meteorites or other external sources. Moreover, it was deposited on a geologically recent timescale. This discovery has important implications for the potential habitability of Europa's ocean. "On Earth, life likes chemical diversity -- the more diversity, the better. We're carbon-based life. Understanding the chemistry of Europa's ocean will help us determine whether it's hostile to life as we know it, or if it might be a good place for life," said Geronimo Villanueva of NASA's Goddard Space Flight Center in Greenbelt, Maryland, lead author of one of two independent papers describing the findings. "We now think that we have observational evidence that the carbon we see on Europa's surface came from the ocean. That's not a trivial thing. Carbon is a biologically essential element," added Samantha Trumbo of Cornell University in Ithaca, New York, lead author of the second paper analyzing these data. NASA plans to launch its Europa Clipper spacecraft, which will perform dozens of close flybys of Europa to further investigate whether it could have conditions suitable for life, in October 2024.

SpaceX Rocket Launches Starlink Satellites On Record-Breaking 17th Flight (space.com) 46

SpaceX just extended its Falcon 9 rocket-reuse record. Space.com reports: The Falcon 9 lifted off from Cape Canaveral Space Force Station in Florida on Tuesday at 11:38 p.m. EDT (0338 GMT Sept. 20), carrying 22 of SpaceX's Starlink internet satellites toward low Earth orbit (LEO). The rocket's first stage came back to Earth 8.5 minutes after launch, landing on a SpaceX drone ship stationed at sea. It was the 17th liftoff and landing for this Falcon 9's first stage, according to a SpaceX mission description.

Those figures are unprecedented; the previous mark was 16, held by two different Falcon 9 boosters. The 22 Starlink satellites, meanwhile, deployed from the Falcon 9's upper stage 62.5 minutes after launch as planned. Tuesday night's liftoff extended another record as well: It was SpaceX's 65th orbital mission of the year. The company's previous mark, 61, was set in 2022.

Space Drugs Factory Denied Reentry To Earth (gizmodo.com) 66

After manufacturing crystals of an HIV drug in space, the first orbital factory is stuck in orbit after being denied reentry back to Earth due to safety concerns. Gizmodo reports: The U.S. Air Force denied a request from Varda Space Industries to land its in-space manufacturing capsule at a Utah training area, while the U.S. Federal Aviation Administration (FAA) did not grant the company permission to reenter Earth's atmosphere, leaving its spacecraft hanging as the company scrambles to find a solution, TechCrunch first reported. A spokesperson from the FAA told TechCrunch in an emailed statement that the company's request was not granted at this time "due to the overall safety, risk and impact analysis."

Gizmodo reached out to Varda Space to ask which regulatory requirements have not been met, but the company responded with a two-word email that ominously read, "no comment." The California-startup did provide an update on its spacecraft through X (formerly Twitter). "We're pleased to report that our spacecraft is healthy across all systems. It was originally designed for a full year on orbit if needed," Varda Space wrote on X. "We look forward to continuing to collaborate w/ our gov partners to bring our capsule back to Earth as soon as possible."
Varda Space Industries launched its first test mission on June 12, "successfully sending a 200-pound (90-kilogram) capsule designed to carry drug research into Earth's orbit," reported CNN. "The experiment, conducted in microgravity by simple onboard machines, aims to test whether it would be possible to manufacture pharmaceuticals in space remotely."

Antarctic Sea-Ice at 'Mind-Blowing' Low Alarms Experts (bbc.com) 200

The sea-ice surrounding Antarctica is well below any previous recorded winter level, satellite data shows, a worrying new benchmark for a region that once seemed resistant to global warming. BBC: "It's so far outside anything we've seen, it's almost mind-blowing," says Walter Meier, who monitors sea-ice with the National Snow and Ice Data Center. An unstable Antarctica could have far-reaching consequences, polar experts warn. Antarctica's huge ice expanse regulates the planet's temperature, as the white surface reflects the Sun's energy back into the atmosphere and also cools the water beneath and near it.

Without its ice cooling the planet, Antarctica could transform from Earth's refrigerator to a radiator, experts say. The ice that floats on the Antarctic Ocean's surface now measures less than 17 million sq km - that is 1.5 million sq km of sea-ice less than the September average, and well below previous winter record lows. That's an area of missing ice about five times the size of the British Isles. Dr Meier is not optimistic that the sea-ice will recover to a significant degree.

Scientists are still trying to identify all the factors that led to this year's low sea-ice - but studying trends in Antarctica has historically been challenging. In a year when several global heat and ocean temperature records have broken, some scientists insist the low sea-ice is the measure to pay attention to. "We can see how much more vulnerable it is," says Dr Robbie Mallett, of the University of Manitoba, who is based on the Antarctic peninsula. Already braving isolation, extreme cold and powerful winds, this year's thin sea-ice has made his team's work even more difficult. "There is a risk that it breaks off and drifts out to sea with us on it," Dr Mallett says.

Avi Loeb Says Meteor Analysis Shows It Originated Outside Our Solar System (usatoday.com) 86

In late August the blog of Harvard professor Avi Loeb declared he had "Wonderful news! For the first time in history, scientists analyzed materials from a meter-size object that originated from outside the solar system."

In July Loeb retrieved parts of a meteor that landed in the waters off of Papua, New Guinea in 2014. A local New York newscast describes the find as "metallic marbles, less than a millimeter in diameter," while Loeb called them "beautiful spheres that were colored — blue, brown or gold."

Now USA Today reports: Early analysis shows that some spherules from the meteor path contain "extremely high abundances" of an unheard-of composition of heavy elements. Researchers on the team say the composition of beryllium, lanthanum and uranium, labeled as a "BeLaU" composition, does not match terrestrial alloys natural to Earth or fallout from nuclear explosions. Additionally, the composition is not found in magma oceans of Earth, nor the moon, Mars or other natural bodies in the solar system.

Other elements are thought to have been lost by evaporation during IM1's passage through the Earth's atmosphere, researchers said, leading them to theorize that the spherules could originate in a magma ocean on an exoplanet with an iron core outside the solar system.

Long-time Slashdot reader Okian Warrior writes that "Technical details can be found here, and a readable accounting of the analysis and results can be found on Avi Loeb's blog." Loeb writes that the exact composition of those spheres are now being studied at three separate laboratories, including one at Harvard.

In July the New York Times published reactions to Loeb's claim that "It's most likely a technological gadget with artificial intelligence." "People are sick of hearing about Avi Loeb's wild claims," said Steve Desch, an astrophysicist at Arizona State University. "It's polluting good science — conflating the good science we do with this ridiculous sensationalism and sucking all the oxygen out of the room." Dr. Desch added that several of his colleagues were now refusing to engage with Dr. Loeb's work in peer review, the process by which scholars evaluate one another's research to ensure that only high-quality studies are published... "What the public is seeing in Loeb is not how science works. And they shouldn't go away thinking that."
Last week Salon also had a few questions for Loeb: In your book, you called Carl Sagan's adage that "extraordinary claims require extraordinary evidence" a "logical fallacy." How and why do you think that statement is somewhat flawed or a logical fallacy?

It's used as an excuse for people who don't want to deal with an exciting possibility. They don't seek the evidence and they argue, "Well, we don't have any evidence...."

If or when we encounter extraterrestrial life, do you think we'll find it or it will find us? Why?

I think we will find it near us because most stars [formed] billions of years before the sun, so it's more likely that some other civilizations preceded us because their star, if it's like the sun, already went through what we in the future might go through. We just need to be humble and modest, not assume that we are unique and special — that Albert Einstein was the smartest scientist who ever lived since the Big Bang — and engage in the search.

That's what I'm trying to do, and the pushback is really strange under these circumstances because the people who argue against it have very strong opinions. But if you look at the history of science, they were very often wrong: the people [who] thought that the earth was the center of the universe, for example.

From Loeb's blog post: During my routine jog at sunrise on the deck of Silver Star, I was asked: "Are you running away from something or towards something?" My answer was: "Both. I am running away from colleagues who have strong opinions without seeking evidence, and I am running towards a higher intelligence in interstellar space."

Conditions On Earth May Be Moving Outside the 'Safe Operating Space' For Humanity (cnn.com) 323

An anonymous reader quotes a report from CNN: Human actions have pushed the world into the danger zone on several key indicators of planetary health, threatening to trigger dramatic changes in conditions on Earth, according to a new analysis from 29 scientists in eight countries. The scientists analyzed nine interlinked "planetary boundaries," which they define as thresholds the world needs to stay within to ensure a stable, livable planet. These include climate change, biodiversity, freshwater and land use, and the impact of synthetic chemicals and aerosols. Human activities have breached safe levels for six of these boundaries and are pushing the world outside a "safe operating space" for humanity, according to the report, published on Wednesday in the journal Science Advances.

The nine boundaries, first set out in a 2009 paper, aim to establish a set of defined "limits" on changes humans are making to the planet -- from pumping out planet-heating pollution to clearing forests for farming. Beyond these limits, the theory goes, the risk of destabilizing conditions on Earth increases dramatically. The limits are designed to be conservative, to enable society to solve the problems before reaching a "very high risk zone," said Katherine Richardson, a professor in biological oceanography at the University of Copenhagen and a co-author on the report. She pointed to the unprecedented summer of extreme weather the world has just experienced at 1.2 degrees Celsius of global warming. "We didn't think it was going to be like this at 1 degree [Celsius]" she said. "No human has experienced the conditions that we're experiencing right now," she added.

Of the three boundaries that scientists found are still within a safe space, two of them -- ocean acidification and the amount of aerosols in the atmosphere -- are moving in the wrong direction. There is some good news, however. The ozone layer was on the wrong side of the boundary in the 1990s, Richardson said. But thanks to international cooperation to phase out ozone-depleting chemicals, it is on track to recover completely. Crossing planetary boundaries does not mean the world has reached a disastrous tipping point. Hitting one does not mean "falling off a cliff," Richardson said. But it is a clear warning signal. The significance of the planetary boundaries model is that it doesn't analyze climate and biodiversity in isolation, the report authors said. Instead, it looks at the interaction of both, as well as a host of other ways humans are affecting the planet. Breaching one boundary is likely to have knock-on effects for others.

Asteroid Behaving Unexpectedly After NASA's Deliberate DART Crash (bbc.co.uk) 36

One year ago NASA crashed its DART spacecraft into the asteroid "Dimorphos" (which orbits around a much larger asteroid named "Didymos"). The BBC calls the mission "part of an experiment to change the space rock's direction and test Earth's defences against asteroids in the future.

"However, a teacher and his class studying the rock have now discovered that since the collision, it has moved in a strange and unexpected way." [U]sing their school telescope, a team of children and their teacher Jonathan Swift at Thacher School in California have found that more than a month after the collision, Dimorphos' orbit continuously slowed after impact... which is unusual and unexpected. As reported in the New Scientist, the team presented their findings at a meeting of the American Astronomical Society.

After discovering the unusual behaviour of Dimorphos, it's likely that Nasa will have to factor in the high school's findings, if they ever launch another asteroid redirection mission in the future... One explanation for the asteroid's orbit continuing to change so long after the Dart collision is that material thrown up by the impact, including rocks several metres across, eventually fell back onto the surface of the asteroid, changing its orbit even more. The European Space Agency is launching a mission called Hera, which will arrive at Dimorphos in 2026 and could reveal more details as to what happened to the asteroid following the impact.

NASA's 'MOXIE' Experiment Successfully Generated 122 Grams of Oxygen on Mars (cnn.com) 70

CNN reports: The first experiment to produce oxygen on another planet has come to an end on Mars after exceeding NASA's initial goals and demonstrating capabilities that could help future astronauts explore the red planet. The microwave-size device called MOXIE, or Mars Oxygen In-Situ Resource Utilization Experiment, is on the Perseverance rover.

The experiment kicked off more than two years ago, a few months after the rover landed on Mars. Since then, MOXIE has generated 122 grams of oxygen, equal to what a small dog breathes in 10 hours, according to NASA. The instrument works by converting some of Mars' plentiful carbon dioxide into oxygen. During the peak of its efficiency, MOXIE produced 12 grams of oxygen an hour at 98% purity or better, which is twice as much as NASA's goals for the instrument. On August 7, MOXIE operated for the 16th and final time, having completed all its requirements...

Bigger and better versions of something such as MOXIE in the future could supply life support systems with breathable air and convert and store oxygen needed for rocket fuel used to launch on a return trip to Earth.

In a statement NASA applauded the performance of the MIT-created experiment. "When the first astronauts land on Mars, they may have the descendants of a microwave-oven-size device to thank for the air they breathe and the rocket propellant that gets them home...

"Rather than bringing large quantities of oxygen with them to Mars, future astronauts could live off the land, using materials they find on the planet's surface to survive."

Can Japan's H2-A Rocket Deliver a Precision-Lander to the Moon? (msn.com) 9

The Washington Post reports: Japan launched a lunar mission Thursday, overcoming multiple failures and delays to become the fifth country to head to the moon — just weeks after India — in a global race to better understand Earth's closest neighbor... It is scheduled to enter the moon's orbit in three to four months and land early next year.

The rocket is carrying two space missions: a new X-ray telescope to help scientists better understand the origins of the universe and a lightweight high-precision moon lander that will serve as the basis for future moon landing technology. The telescope separated at 8:56 a.m., and the moon lander separated at 9:29 a.m...

Japan has made several attempts to reach the moon, including its Omotenashi project to land an ultrasmall probe. In November, Japan abandoned the project after failing to restore communications with the spacecraft. Earlier this year, Tokyo-based space company ispace also pulled the plug on the first Japanese private-sector attempt to land on the moon.

Japan's high-precision lander hopes to land within 328 feet (100 meters) of its target — which the article says it "much closer than conventional lunar landers, which usually have an accuracy of several kilometers."

Starship Is Stacked and Ready To Make Its Second Launch Attempt (arstechnica.com) 89

SpaceX's Starship rocket is fully stacked and ready to launch again. According to Elon Musk, the company is just waiting for the Federal Aviation Administration (FAA) to approve the launch license. Ars Technica reports: That caveat is a big one because the Federal Aviation Administration is still reviewing paperwork and data from SpaceX about the first launch attempt of Starship in April 2023. That flight ended after about 90 seconds due to engine problems and other issues with the booster. The FAA has been reviewing data from that accident, including the environmental implications at the launch site and the delayed activation of the rocket's flight termination system. Following this accident, SpaceX prepared and submitted a "mishap investigation report" to the FAA. After reviewing the report, the FAA will identify corrective actions that the company must make ahead of its second test flight to ensure the safety of people, property, and wildlife near the South Texas launch site, which is surrounded by wetlands and the Gulf of Mexico. [...]

During the upcoming test flight, Starship will carry no payloads but will instead seek to demonstrate the performance of the booster's 33 Raptor rocket engines, stage separation, and ignition of Starship's six engines. Under a nominal flight, Starship will complete nearly three-quarters of an orbit around Earth before splashing down in the Pacific Ocean, north of the Hawaiian island of Kauai. The launch date is pending regulatory approval, but it is not expected to occur before the middle of September.

'Alarming' Scale of Marine Sand Dredging Laid Bare by New Data Platform (theguardian.com) 64

One million lorries of sand a day are being extracted from the world's oceans, posing a "significant" threat to marine life and coastal communities facing rising sea levels and storms, according to the first-ever global data platform to monitor the industry. From a report: The new data platform, developed by the UN Environment Programme (Unep), tracks and monitors dredging of sand in the marine environment by using the AIS (automatic identification systems) data from ships. Using data from 2012-19, Marine Sand Watch estimates the dredging industry is digging up 6bn tonnes of marine sand a year, a scale described as "alarming." The rate of extraction is growing globally, Unep said, and is approaching the natural rate of replenishment of 10bn to 16bn tonnes of sand flowing into the sea from rivers and needed to maintain coastal structure and ecosystems.

The platform has identified "hotspots" including the North Sea, south-east Asia and the east coast of the United States as areas of concern. In many places where extraction is more intense, including parts of Asia, marine sand is being extracted well beyond the rate at which it is being replenished from rivers. [...] Developed by GRID-Geneva, a centre for analytics within Unep, Marine Sand Watch has trained artificial intelligence to identify the movement of dredging vessels from its AIS data. It has data from 2012-19 from Global Fishing Watch, a company set up to track commercial fishing activities using AIS data from fishing vessels, but is working on more recent data.

It's Time To Put Oceans To the Test in the Climate Fight, Scientists Say (theverge.com) 98

More than 200 scientists have signed onto a letter pushing for "responsible" research into ways to trap planet-heating carbon dioxide in the world's oceans. They want to take urgent action on the climate crisis, while making sure they don't trigger any new problems by relying on oceans to help in the fight. From a report: Polluters have trashed the world's atmosphere with carbon dioxide emissions from fossil fuels. That blanket of pollution is already warming the planet and causing more extreme weather disasters. One way to keep climate change from getting worse is to take some of those historic emissions out of the atmosphere.

Oceans already do that for us, absorbing and holding around 50 times more carbon than the atmosphere. What if humans could supercharge that ability? That's what scientists want to better understand, along with any side effects that might come with messing with the chemistry of our oceans. Startups are already developing new technologies to sequester more CO2 in the sea. But there's still a lot we don't know about what impact that might have or what strategies might be most successful, the letter says.

Invasive Species Cost Humans $423 Billion Each Year and Threaten World's Diversity (theguardian.com) 57

Invasive species are costing the world at least $423bn every year and have become a leading threat to the diversity of life on Earth, according to a UN assessment. From a news report: From invasive mice that eat seabird chicks in their nests to non-native grasses that helped fuel and intensify last month's deadly fires in Hawaii, at least 3,500 harmful invasive species have been recorded globally in every region, spread by human travel and trade. Their impact is destructive for humans and wildlife, sometimes causing extinctions and permanently damaging the healthy functioning of an ecosystem.

Leading scientists say the threat posed by invasive species is under appreciated, underestimated and sometimes unacknowledged, with more than 37,000 alien species now known to be introduced around the world and about 200 establishing themselves each year. While not all will become invasive, experts say there are significant tools to mitigate their spread and impact, protecting and restoring ecosystems in the process.

"Invasive alien species are a major threat to biodiversity and can cause irreversible damage to nature, including local and global species extinctions, and also threaten human wellbeing," wrote Prof Helen Roy, Prof Anibal Pauchard and Prof Peter Stoett, who led the research. "It would be an extremely costly mistake to regard biological invasions only as someone else's problem," said Pauchard. "Although the specific species that inflict damage vary from place to place, these are risks and challenges with global roots but very local impacts facing people in every country, from all backgrounds and in every community -- even Antarctica is being affected."

Mission Accomplished, India Puts Moon Rover to 'Sleep' for 14 Days (reuters.com) 34

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

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

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

India Seeks To Top Its Moon Landing with Spacecraft To Study Sun (bloomberg.com) 18

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

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

Starfield's 1,000 Planets May Be One Giant Leap for Game Design 106

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

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

NASA Officials Sound Alarm Over Future of the Deep Space Network (arstechnica.com) 49

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

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

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

UN Backs New Term For Conservation Talks (theguardian.com) 33

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

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