Reason.com notes NASA's successful completion of its Artemis I mission, calling it "part of NASA's ambitious program to bring American astronauts back to the moon for the first time in half a century. And then on to Mars."

But then they ask if the project is worth the money, with the transportation policy director at the libertarian "Reason Foundation" think tank, Robert W. Poole, arguing instead that NASA "isn't particularly interested in cost savings, and its decision making is overly driven by politics." NASA would have been better off replacing the costly and dated Space Launch System used in the Artemis program. But it didn't. This probably has a lot to do with the fact that it was largely constructed and engineered in Alabama, the home state of Senate Appropriations Committee Chair Richard Shelby, who has a history of strong-arming NASA to preserve jobs for his constituents.
Long-time Slashdot reader SonicSpike shared the article, which ultimately asks whether it'd be faster and cheaper to just rely on private companies: In 2009, the private sector saw one of its biggest champions ascend to become the number two person at NASA. Lori Garver pushed to scrap the Constellation program as a way to entice the private sector to fill in the gaps. She also spearheaded the Commercial Crew Program, which continues to employ commercial contractors to ferry astronauts to the International Space Station. Today, companies like Elon Musk's SpaceX are launching rockets at a faster pace and for a fraction of what NASA spends. In 2022, the company successfully launched 61 rockets, each with a price tag between $100 million and 150 million.

Private companies already design and lease NASA much of its hardware. Poole says there's no reason NASA can't take it a step further and just use the SpaceX starship to cover the entire journey from Earth to the moon and eventually to Mars. "If the current NASA plan goes ahead to have the SpaceX Starship actually deliver the astronauts from the lunar outpost orbit to the surface of the moon and bring them back, that would be an even more dramatic refutation of the idea that only NASA should be doing space transportation," he says.

Poole says that instead of flying its own missions, NASA should play a more limited and supportive role. "The future NASA role that makes the most sense is research and development to advance science," he says.
But for a contrary opinion, Slashdot reader youn counters that "You can bash NASA all you want but a big reason the private sector is where it is at is because it funded research 12 years ago." They share a CNET article noting the $6 billion NASA budgeted over five years "to kick-start development of a new commercial manned spaceflight capability."

And Slashdot reader sg_oneill argues that "Its gonna be a century before we're really colonizing the moon and/or Mars... because we have a lot of science to do first. How do you do a civilization with zero energy inputs from the rest of humanity? How do we deal with radiation? How do bodies work in low G? (Mars is about 1/3 the gravbity of earth). This needs science, and to get science we need NASA, even if private enterprise is building the rockets."

"As a quick follow-up to yesterday's post about InSight's final photo, the InSight Lander's mission is now officially over after 2 failed communications attempts," writes Slashdot reader davidwr. From a NASA press release: NASA's InSight mission has ended after more than four years of collecting unique science on Mars. Mission controllers at the agency's Jet Propulsion Laboratory (JPL) in Southern California were unable to contact the lander after two consecutive attempts, leading them to conclude the spacecraft's solar-powered batteries have run out of energy -- a state engineers refer to as "dead bus."

"I watched the launch and landing of this mission, and while saying goodbye to a spacecraft is always sad, the fascinating science InSight conducted is cause for celebration," said Thomas Zurbuchen, associate administrator of NASA's Science Mission Directorate in Washington. "The seismic data alone from this Discovery Program mission offers tremendous insights not just into Mars but other rocky bodies, including Earth." You can read more about the InSight Mars Lander at NASA's website.

NASA's InSight lander has probably phoned home for the last time from the planet Mars. From a report: The space agency said the spacecraft did not respond to communications from Earth on Sunday, December 18. The lack of communications came as the lander's power-generating capacity has been declining in recent months due to the accumulation of Martian dust on its solar panels. NASA said that it is "assumed" that InSight has reached the end of its operations but that it will continue to try to contact the lander in the coming days. Also on Monday, the InSight Twitter account shared a photo with a message saying this was probably the last photo it was sending from Mars. UPDATE 12/21/22: NASA's InSight Mission Officially Over

A new study published in Nature Astronomy assessed the viability of turbines as an energy source for future Mars missions, and "the results hint that wind power could be an important pillar of energy generation on the red planet, assuming humans are able to successfully land there in the coming decades," reports Motherboard. From the report: Scientists have generally written off wind power as a key energy source for Mars missions, compared to solar and nuclear power, because Martian winds are extremely weak. Now, a team led by Victoria Hartwick, a postdoctoral fellow at NASA Ames Research Center, has used global climate models of Mars to show that, contrary to past assumptions, "wind power represents a stable, sustained energy resource across large portions of the Mars surface," according to the study. "Using a state-of-the-art Mars global climate model, we analyze the total planetary Martian wind potential and calculate its spatial and temporal variability," Hartwick and her colleagues said in the study. "We find that wind speeds at some proposed landing sites are sufficiently fast to provide a stand-alone or complementary energy source to solar or nuclear power." "Wind energy represents a valuable but previously dismissed energy resource for future human missions to Mars, which will be useful as a complementary energy source to solar power," the team added.

To assess whether wind power could fill that gap, Hartwick and her colleagues used the NASA Ames Mars global climate model to estimate wind speeds across the planet. Since Mars' atmosphere is very thin, with only 1 percent the density of Earth's atmosphere, Martian winds are pretty wimpy everywhere. Even so, the researchers found that several tantalizing locations could theoretically use wind as the only source of power, and that a combination of solar and wind power would unlock sites across a huge swath of the planet -- including icy locations at the poles.

To that point, the team identified several sites that would be particularly conducive to wind power, including locations within the icy northern regions of Deuteronilus Mensae and Protonilus Mensae. The researchers envision setting up medium-sized turbines, measuring 50 meters (160 feet) tall, to catch the stronger winds in these areas, allowing astronauts to subsist in the strange glacial terrain of an alien world. Turbines could also be effective if placed near topographical gradients, such as crater rims or the slopes of ancient volcanoes, to catch the gusts generated by these landscapes.

The New York Times cites predictions from American's Defense Department that China could surpass U.S. space capabilities as soon as 2045. "I think it's entirely possible they could catch up and surpass us, absolutely," said the staff director of the United States Space Force. "The progress they've made has been stunning — stunningly fast."

But in a new article this week, the newspaper notes that China recenty sent space probes to the moon and to Mars — and invited foreign media to the launch of its space station in November — and looks back over decades of development: Thirty years ago, the Chinese government initiated a secret plan for its space program, including a key goal of building a space station by 2020. At the time, the country was 11 years from sending its first astronaut into space, and its space efforts were going through a rough patch: Chinese rockets failed in 1991, 1992, 1995 and twice in 1996. The worst failure, in 1996, was a rocket that tipped to the side, flew in the wrong direction and exploded 22 seconds after launch, showering a Chinese village with falling wreckage and flaming fuel that killed or injured at least 63 people.

While grand spaceflight plans of some nations have ended up many years behind schedule, China completed the assembly in orbit of its Tiangong space station in late October, only 22 months later than planned. And on Nov. 29, the Shenzhou 15 mission blasted off from China's Jiuquan Satellite Launch Center deep in the Gobi Desert and took three astronauts to the space station to begin permanent occupancy of the outpost.
The article notes that the U.S. Congress "ended up banning American space agencies in 2011 from spending any money to cooperate in space with China, except in limited circumstances."

But today Zhou Jianping, chief designer of China's crewed space program, asserts that "within a few years, we will be able to achieve the reuse of re-entry capsules for our new generation spaceships." Sending a person to Mars is an even bigger prize for China. It has placed an emphasis on shortening the duration of such a trip, perhaps with nuclear propulsion instead of conventional rocket engines. Officials are also determined that any journey will be a round-trip from which all astronauts return alive and in good health.... With nuclear propulsion, the trip could be trimmed to 500 days, Mr. Zhou said, without predicting whether China would adopt that approach.

One of the great differences between Mars and Earth involves what's going on beneath the surface. Our planet remains a tectonically and volcanically active world -- witness the current eruptions in Hawaii -- while Mars has been a cold, geologically dead place for the past three billion years. That was the thinking at least. But a new paper in Nature Astronomy challenges that accepted wisdom. Mars, it suggests, may still be geologically active today. Time: The findings are the result of orbital photography, surface data, and computer modeling of a lowland region near the Martian equator known as Elysium Planitia -- where NASA's Mars InSight probe landed in 2018. Researchers from the University of Arizona Lunar and Planetary Laboratory analyzed recordings of Mars quakes taken by InSight and concluded that they all result from a series of subsurface fissures dubbed Cerberus Fossae, which stretch nearly 1,300 km (800 mi.) across the Martian surface. This gives rise to what are known as mantle plumes: blob-like masses of molten rock that rise to reach the base of the crust, causing quakes, faulting, and volcanic eruptions. Computer modeling of the region indicates that far from being geologically dead, Elysium Planitia experienced major volcanic eruptions as recently as 200 million years ago.

The Viking 1 lander arrived on the Martian surface 46 years ago to investigate the planet. It dropped down into what was thought to be an ancient outflow channel. Now, a team of researchers believes they've found evidence of an ancient megatsunami that swept across the planet billions of years ago, less than 600 miles from where Viking landed. Gizmodo reports: In a new paper published today in Scientific Reports, a team identified a 68-mile-wide impact crater in Mars' northern lowlands that they suspect is leftover from an asteroid strike in the planet's ancient past. "The simulation clearly shows that the megatsunami was enormous, with an initial height of approximately 250 meters, and highly turbulent," said Alexis Rodriguez, a researcher at the Planetary Science Institute and lead author of the paper, in an email to Gizmodo. "Furthermore, our modeling shows some radically different behavior of the megatsunami to what we are accustomed to imagining."

Rodriguez's team studied maps of the Martian surface and found the large crater, now named Pohl. Based on Pohl's position on previously dated rocks, the team believes the crater is about 3.4 billion years old -- an extraordinarily long time ago, shortly after the first signs of life we know of appeared on Earth. According to the research team's models, the asteroid impact could have been so intense that material from the seafloor may have dislodged and been carried in the water's debris flows. Based on the size of the crater, the team believes the impacting asteroid could have been 1.86 miles wide or 6 miles wide, depending on the amount of ground resistance the asteroid encountered. The impact could have released between 500,000 megatons and 13 million megatons of TNT energy (for comparison, the Tsar Bomba nuclear test was about 57 megatons of TNT energy.) "A clear next step is to propose a landing site to investigate these deposits in detail to understand the ocean's evolution and potential habitability," Rodriguez said. "First, we would need a detailed geologic mapping of the area to reconstruct the stratigraphy. Then, we need to connect the surface modification history to specific processes through numerical modeling and analog studies, including identifying possible mud volcanoes and glacier landforms."

James Cameron once got himself onto the list for a potential visit to the International Space Station. It's just one of several surprising scientific achievements buried deep inside GQ's massive 7,000-word profile: After James Cameron's Avatar came out in 2009 and made $2.7 billion, the director found the deepest point that exists in all of earth's oceans and, in time, he dove to it. When Cameron reached the bottom of the Mariana Trench, a couple of hundred miles off the southwest coast of Guam, in March 2012, he became the first person in history to descend the 6.8-mile distance solo, and one of only a few people to ever go that deep....

It would be fair to call him the father of the modern action movie, which he helped invent with his debut, The Terminator, and then reinvent with his second, Aliens; it would be accurate to add that he has directed two of the three top-grossing films in history, in Avatar (number one) and Titanic (number three). But he is also a scientist — a camera he helped design served as the model for one that is currently on Mars, attached to the Mars rover — and an adventurer, and not in the dilettante billionaire sense; when Cameron sets out to do something, it gets done. "The man was born with an explorer's instincts and capacity," Daniel Goldin, the former head of NASA, told me....

The original Avatar... required the invention of dozens of new technologies, from the cameras Cameron shot with to the digital effects he used to transform human actors into animated creatures to the language those creatures spoke in the film. For [his upcoming Avatar sequel] The Way of Water, Cameron told me, he and his team started all over again. They needed new cameras that could shoot underwater and a motion-capture system that could collect separate shots from above and below water and integrate them into a unified virtual image; they needed new algorithms, new AI, to translate what Cameron shot into what you see....

Among other things, Cameron said, The Way of Water would be a friendly but pointed rebuke to the comic book blockbusters that now war with Cameron's films at the top of the box office lists: "I was consciously thinking to myself, Okay, all these superheroes, they never have kids. They never really have to deal with the real things that hold you down and give you feet of clay in the real world." Sigourney Weaver, who starred in the first Avatar as a human scientist and returns for The Way of Water as a Na'vi teenager, told me that the parallels between the life of the director and the life of his characters were far from accidental: "Jim loves his family so much, and I feel that love in our film. It's as personal a film as he's ever made."
Another interesting detail from the article: Cameron and his wife became vegetarians over a decade ago, built their own pea-protein facility in Saskatchewan, and though they later sold it Cameron says he "pretty much" loves farming and pea protein as much as movies. And he once suggested re-branding the word vegan as "futurevore," since "We're eating the way people will eat in the future. We're just doing it early."

But in a 29-minute video interview, Cameron also fondly discusses his earlier ground-breaking films, even as GQ's writer notes their new trajectory. "It is a curious fact that Cameron has directed only two feature films in the last 25 years — and perhaps more curious that both are Avatar installments, and perhaps even more curious that the next three films he hopes to direct are also Avatar sequels....

"Cameron told me he'd already shot all of a third Avatar, and the first act of a fourth. There is a script for a fifth and an intention to make it, as long as the business of Avatar holds up between now and then. It seems entirely possible — maybe even probable — that Cameron will never make another non-Avatar film again."

"News from Mars," CNN reported Friday. "Not just that water was there, perhaps millions of years ago, but also these organic compounds."

In an interview with the head of Earth Sciences collections at the UK's Natural History Musem, CNN asked the million-dollar question. "How much more likely, if you believe so, that that makes it that there was life on Mars at some time." A: So what we've found with data that's come back from the Rover and has been studied over the last few months is that we see igneous rocks -- so these are rocks that have been formed through volcanic processes -- which have also been affected by the action of liquid water.

And that's really really interesting and exciting, because liquid water is one of the key ingredients you need for life to start. So if you've got the chances of life ever being on Mars, you'd need to have somewhere that had liquid water for at least a period of time. And we've got good evidence for that.

Now that's combined with the fact that we're seeing, using instruments like SHERLOCK, which is an instrument that I'm involved with, also the presence of organic molecules. And organic molecules are chemical molecules made of the elements carbon, hydrogen, oxygen, nitrogen, sometimes bits of sulfur, sometimes bits of phosphorous, and maybe some added-up things. And those are really really important, because you need organic molecules for life to start.

And the other thing that's really interesting about organic molecules is they can actually be sort of fossil chemical evidence of potential past life.

About an hour ago SpaceX began tweeting video highlights of their latest launch — a NASA-commissioned resupply mission for the International Space Station.

- "Liftoff!"

- "Falcon 9's first stage has landed on the Just Read the Instructions droneship"

- "Dragon separation confirmed; autonomous docking to the Space Station on Sunday, November 27 at ~7:30 a.m. ET"

You can watch the whole launch on SpaceX's web site. But CNN explains that SpaceX "has launched more than two dozen resupply missions to the space station over the past decade as part of a multibillion-dollar deal with NASA. This launch comes amid SpaceX's busiest year to date, with more than 50 operations so far, including two astronaut missions."

And yet this one carries something unique. (And it's not just the Thanksgiving-themed treats and solar arrays to boost the space station's power...) Nutrients are a key component of maintaining good health in space. But fresh produce is in short supply on the space station compared with the prepackaged meals astronauts eat during their six-month stays in low-Earth orbit. "It is fairly important to our exploration goals at NASA to be able to sustain the crew with not only nutrition but also to look at various types of plants as sources for nutrients that we would be hard-pressed to sustain on the long trips between distant destinations like Mars and so forth," said Kirt Costello, chief scientist at NASA's International Space Station Program and a deputy manager of the ISS Research Integration Office.

Astronauts have grown and tasted different types of lettuce, radishes and chiles on the International Space Station. Now, the crew members can add some dwarf tomatoes — specifically, Red Robin tomatoes — to their list of space-grown salad ingredients. The experiment is part of an effort to provide continuous fresh food production in space.... The space tomatoes will be grown inside small bags called plant pillows installed in the Vegetable Production System, known as the Veggie growth chamber, on the space station. The astronauts will frequently water and nurture the plants....

The hardware is still in development for larger crop production on the space station and eventually other planets, but scientists are already planning what plants might grow best on the moon and Mars. Earlier this year, a team successfully grew plants in lunar soil that included samples collected during the Apollo missions. "Tomatoes are going to be a great crop for the moon," Massa said. "They're very nutritious, very delicious, and we think the astronauts will be really excited to grow them there."

In 1999, Slashdot editor Hemos said Greg Bear was "rightly recognized as a master of hard science fiction" (introducing a review of Bear's then-new book, Nebula-winning book Darwin's Radio). In 2011 Bear began writing the Forerunner Saga , a trilogy of books set 100,000 years before the events in the game Halo.

Today theGamer.com writes that Bear has passed away at age 71: Bear's family and fans are paying tribute to the legendary author, who had more than 50 sci-fi novels to his name. Many share fond memories of reading Bear's work and meeting him at conventions, describing him as generous, welcoming, and brilliant. Fans are also sharing their favourite books from Bear in tribute, encouraging others to explore his works to celebrate his legacy.

Bear's wife, Astrid Bear, confirmed the news of his passing in the early hours of Sunday. This was after she revealed that her husband has been placed on life support, with no chance of making a full recovery after the stroke.
More from File770.com: Bear's novels won Nebulas for Moving Mars (1995) and Darwin's Radio. Three other works of short fiction won Nebulas, and two of those — "Blood Music" (1984) and "Tangents" (1987) — also won the Hugo....

Bear sold his first short story, "Destroyers", to Famous Science Fiction at age 15, and along with high-school friends helped found San Diego Comic-Con.

He also published work as an artist at the beginning of his career, including illustrations for an early version of theÂStar Trek Concordance,Âand covers forÂGalaxyÂandÂF&SF. He was a founding member of the Association of Science Fiction Artists. He even created the cover for his novel, Psychlone...

NASA's Artemis 1 rocket blasted off the Kennedy Space Center in the early hours of Wednesday, "lighting up the night sky and accelerating on a journey that will take an astronaut-less capsule around the moon and back," reports the New York Times. From the report: At around 1:47 a.m. Eastern time, the four engines on the rocket's core stage ignited, along with two skinnier side boosters. As the countdown hit zero, clamps holding the rocket down let go, and the vehicle slipped Earth's bonds. A few minutes later, the side boosters and then the giant core stage dropped away. The rocket's upper engine then ignited to carry the Orion spacecraft, where astronauts will sit during later missions, toward orbit. Less than the two hours after launch, the upper stage will fire one last time to send Orion on a path toward the moon. On Monday, Orion will pass within 60 miles of the moon's surface. After going around the moon for a couple of weeks, Orion will head back to Earth, splashing down on Dec. 11 in the Pacific Ocean, about 60 miles off the coast of California.

This flight, evoking the bygone Apollo era, is a crucial test for NASA's Artemis program that aims to put astronauts, after five decades of loitering in low-Earth orbit, back on the moon. For NASA, the mission ushers in a new era of lunar exploration, one that seeks to unravel scientific mysteries in the shadows of craters in the polar regions, test technologies for dreamed-of journeys to Mars and spur private enterprise to chase new entrepreneurial frontiers farther out in the solar system. [...] The launch occurred years behind schedule, and billions of dollars over budget. The delays and cost overruns of S.L.S. and Orion highlight the shortcomings of how NASA has managed its programs. The next Artemis mission, which is to take four astronauts on a journey around the moon but not to the surface, will launch no earlier than 2024. Artemis III, in which two astronauts will land near the moon's south pole, is currently scheduled for 2025, though that date is very likely to slip further into the future. NASA posted a video of the liftoff on their Twitter. Additional updates are available @NASA_SLS.

The original story from Space.com: NASA's Artemis 1 moon mission will once again attempt to launch after all. Mission managers met on Monday (Nov. 14) to discuss the flight readiness of the Artemis 1's Space Launch System (SLS) rocket and Orion spacecraft following slight damage caused by Hurricane Nicole, which was swiftly downgraded to a tropical storm after making landfall, on Thursday (Nov. 10). Despite the fact that a band of insulating caulking on Orion was damaged by high winds during the storm's landfall, Mike Sarafin, Artemis mission manager at NASA headquarters in Washington, said "there's no change in our plan to attempt to launch on the 16th" during a media teleconference today (Nov. 14).

"The unanimous recommendation for the team was that we were in a good position to go ahead and proceed with the launch countdown," added Jeremy Parsons, deputy manager of NASA's Exploration Ground Systems program at Kennedy Space Center (KSC) in Florida. If all goes according to plan during additional preflight checks and the cryogenic fueling process on Tuesday (Nov. 15), the Artemis 1 mission will launch from Launch Pad 39B at 1:04 a.m. EST (0604 GMT) on Nov. 16. You can watch the countdown, fueling and launch of Artemis 1 live online here on Space.com courtesy of NASA.

The United Nations is betting that satellites could help the world catch up on emissions reductions. From a report: The organization has unveiled a Methane Alert and Response System (MARS) that, as the name implies, will warn countries and companies of "major" methane emission releases. The technology will use satellite map data to identify sources, notify the relevant bodies and help track progress on lowering this output.

The initial MARS platform will focus on "very large" energy sector sources. It'll gradually expand to include less powerful sources, more frequent alerts and data from animals, coal, rice and waste. Partners in the program, such as the International Energy Agency and UN's Climate and Clean Air Coalition, will provide help and advice. The information also won't remain a secret, as the UN will make both data and analyses public between 45 to 75 days after it's detected. The system will get its early funding from the US government, European Commission, Bezos Earth Fund and the Global Methane Hub. Both Bezos' fund and GMH are backing related efforts, such as studies on spotting and counteracting agricultural methane emissions.

On Thursday morning, NASA sent a giant inflatable device to space and then brought it back down from orbit, splashing in the ocean near Hawaii. From a report: You might think of it as a bouncy castle from space, although the people in charge of the mission would prefer you did not. "I would say that would be inaccurate," Neil Cheatwood, principal investigator for the Low-Earth Orbit Flight Test of an Inflatable Decelerator, or LOFTID for short, said of the comparison during an interview. LOFTID may sound like just an amusing trick, but the $93 million project demonstrates an intriguing technology that could help NASA in its goal of getting people safely to the surface of Mars someday. The agency has landed a series of robotic spacecraft on Mars, but the current approaches only work for payloads weighing up to about 1.5 tons -- about the bulk of a small car. That is inadequate for the larger landers, carrying 20 tons or more, that are needed for people and the supplies they will need to survive on the red planet.

A more accurate description of the device might be that it is a saucer, 20 feet wide when inflated. It is made of layers of fabric that can survive falling into the atmosphere at 18,000 miles per hour and temperatures close to 3,000 degrees Fahrenheit. Still, an inflatable heat shield shares a key characteristic with a bouncy castle: Uninflated, it can be folded and packed tightly. LOFTID fit in a cylinder a bit over four feet wide and one and a half feet high. For a traditional rigid heat shield, there is no way to cram something 20 feet in diameter into a rocket that is not that wide. A larger surface like LOFTID's generates much more air friction -- essentially it is a better brake as it slices through the upper atmosphere, and the greater drag allows heavier payloads to be slowed down. For future Mars missions, the inflatable heat shield would be combined with other systems like parachutes and retrorockets to guide the lander en route to a soft landing.

Rocket designers with China's main launch vehicle institute have scrapped plans for an expendable super heavy-lift launcher in favor of a design featuring a reusable first stage. SpaceNews reports: A new model of a Long March 9 rocket featuring grid fins and no side boosters recently went on display at the ongoing Zhuhai Airshow in southern China, prompting speculation that the long-standing plan of an expendable rocket had been dropped. Liu Bing, director of the general design department at the China Academy of Launch Vehicle Technology (CALT), later confirmed the new direction in an interview with China Central Television Nov. 7.

The new, current plan for the rocket will be a three-stage, 108-meter-high, 10-meter-diameter and 4,180 metric ton rocket capable of delivering 150 tons to low Earth orbit (LEO), 50 tons to lunar transfer orbit (LTO), or 35 tons to Mars transfer orbit. The rocket is scheduled to be ready for test flight around 2030. Liu told CCTV however that the design has not been finalized and will likely see changes as the team selects the optimal pathway, while committing to the goal of constantly breaking through technological challenges and increasing its launching power.

CNET reports on how research in Antarctica "could change astronomy forever": About 47 million light-years from where you're sitting, the center of a black-hole-laden galaxy named NGC 1068 is spitting out streams of enigmatic particles. These "neutrinos" are also known as the elusive "ghost particles" that haunt our universe but leave little trace of their existence.... Nestled into about 1 billion tons of ice, more than 2 kilometers (1.24 miles) beneath Antarctica, lies the IceCube Neutrino Observatory. A neutrino hunter, you might call it. When any neutrinos transfer their party to the frigid continent, IceCube stands ready.

In a paper published Friday in the journal Science, the international team behind this ambitious experiment confirmed it has found evidence of 79 "high-energy neutrino emissions" coming from around where NGC 1068 is located, opening the door for novel — and endlessly fascinating — types of physics. "Neutrino astronomy," scientists call it.

It'd be a branch of astronomy that can do what existing branches simply cannot.

Before today, physicists had only shown neutrinos coming from either the sun; our planet's atmosphere; a chemical mechanism called radioactive decay; supernovas; and — thanks to IceCube's first breakthrough in 2017 — a blazar, or voracious supermassive black hole pointed directly toward Earth. A void dubbed TXS 0506+056. With this newfound neutrino source, we're entering a new era of the particle's story. In fact, according to the research team, it's likely neutrinos stemming from NGC 1068 have up to millions, billions, maybe even trillions the amount of energy held by neutrinos rooted in the sun or supernovas. Those are jaw-dropping figures because, in general, such ghostly bits are so powerful, yet evasive, that every second, trillions upon trillions of neutrinos move right through your body. You just can't tell....

Not only is this moment massive because it gives us more proof of a strange particle that wasn't even announced to exist until 1956, but also because neutrinos are like keys to our universe's backstage. They hold the capacity to reveal phenomena and solve puzzles we're unable to address by any other means, which is the primary reason scientists are trying to develop neutrino astronomy in the first place.... Expected to be generated behind such opaque screens filtering our universe, these particles can carry cosmic information from behind those screens, zoom across great distances while interacting with essentially no other matter, and deliver pristine, untouched information to humanity about elusive corners of outer space.
The team says their data can provide information on two great unsolved mysteries in astronomy: why black holes emit sporadic blasts of light, and neutrinos' suspected role in the origin of cosmic rays.

The mission of NASA's robotic lander InSight "is nearing an end as dust obscures its solar panels," reports CNN. "In a matter of weeks, the lander won't be able to send a beep to show it's OK anymore."

"Before it bids farewell, though, the spacecraft still has some surprises in store." When Mars rumbled beneath InSight's feet on December 24, NASA scientists thought it was just another marsquake. The magnitude 4 quake was actually caused by a space rock slamming into the Martian surface a couple thousand miles away. The meteoroid left quite a crater on the red planet, and it revealed glimmering chunks of ice in an entirely unexpected place — near the warm Martian equator.
The chunks of ice — the size of boulders — "were found buried closer to the warm Martian equator than any ice that has ever been detected on the planet," CNN explained earlier this week. The article also adds that ice below the surface of Mars "could be used for drinking water, rocket propellant and even growing crops and plants by future astronauts. And the fact that the ice was found so near the equator, the warmest region on Mars, might make it an ideal place to land crewed missions to the red planet." Interestingly, they note that scientists only realized it was a meteoroid strike (and not an earthquake) when "Before and after photos captured from above by the Mars Reconnaissance Orbiter, which has been circling Mars since 2006, spotted a new crater this past February." A crater that was 492 feet (150 meters) across and 70 feet (21 meters) deep... When scientists connected the dots from both missions, they realized it was one of the largest meteoroid strikes on Mars since NASA began studying the red planet.... The journal Science published two new studies describing the impact and its effects on Thursday....

"The image of the impact was unlike any I had seen before, with the massive crater, the exposed ice, and the dramatic blast zone preserved in the Martian dust," said Liliya Posiolova, orbital science operations lead for the orbiter at Malin Space Science Systems in San Diego, in a statement....

Researchers estimated the meteoroid, the name for a space rock before it hits the ground, was about 16 to 39 feet (5 to 12 meters). While this would have been small enough to burn up in Earth's atmosphere, the same can't be said for Mars, which has a thin atmosphere only 1% as dense as Earth's.... Some of the material blasted out of the crater landed as far as 23 miles (37 kilometers) away.

Teams at NASA also captured sound from the impact, so you can listen to what it sounds like when a space rock hits Mars. The images captured by the orbiter, along with seismic data recorded by InSight, make the impact one of the largest craters in our solar system ever observed as it was created.

NASA obligated $2.04 billion to SpaceX in fiscal year 2022, which ended last month, according to new federal procurement data. For the first time, the amount paid by the space agency to SpaceX exceeds that paid to Boeing, which has long been the leading hardware provider to NASA. Boeing received $1.72 billion during the most recent fiscal year, based on data first reported by Aviation Week's Irene Klotz. Ars Technica reports: The California Institute of Technology, which manages the Jet Propulsion Laboratory field center for NASA, remains the agency's No. 1 contractor, with $2.68 billion in funding. The academic institution is responsible for operating the California-based NASA field center and distributing funding for myriad robotic spacecraft missions such as Mars Perseverance and the Europa Clipper. On the one hand, the ascension of SpaceX to the No. 2 spot on NASA's contractor list represents a major shakeup in the order of things. For a long time, NASA's human spaceflight and exploration programs were dominated by Boeing, Lockheed Martin, Aerojet, Northrop Grumman, and a handful of other traditional defense aerospace contractors.

However, it should come as no surprise that a company that has recently delivered the most services -- and, arguably, value -- to NASA should start to receive a large share of its contract awards. This has been most notable with SpaceX's performance on Commercial Crew, NASA's program to buy transportation services from private companies to bring its astronauts to and from the International Space Station. NASA awarded contracts to Boeing and SpaceX in 2014 to develop their spacecraft, paying Boeing about 60 percent more. At the time, it was widely believed that the traditional contractor, with this additional money, would deliver services sooner. But it was SpaceX that first flew crew to the space station in May 2020, and the company has since launched five operational missions to the orbiting laboratory. [...] Much of the funding increase for SpaceX in 2022, an increase of about $400 million over the previous year, appears to be driven by contracts for the Human Landing System as part of the Artemis Moon Program and the purchase of additional Crew Dragon missions to the space station. (Individual contracts can be found within the Federal Procurement Data System).

One of Earth's toughest microbes could survive on Mars, lying dormant beneath the surface, for 280 million years, new research has shown. The findings increase the probability that microbial life could still exist on the Red Planet. Space.com reports: Deinococcus radiodurans, nicknamed "Conan the Bacterium," is one of the world's toughest microbes, capable of surviving in radiation strong enough to kill any other known life-form. Experiments have now shown that if Conan the Bacterium or a similar microbe existed on Mars, it could survive 33 feet (10 meters) beneath the surface, frozen and dried out, for 280 million years. In a study led by Michael Daly, who is a professor of pathology at Uniformed Services University of the Health Sciences in Maryland and a member of the National Academies' Committee on Planetary Protection, scientists tested half a dozen microbes and fungi -- all "extremophiles" able to live in environments where other organisms die -- to see how long they could survive in an environment that simulated the mid-latitudes of Mars. During the experiments, organisms faced temperatures as low as minus 80 degrees Fahrenheit (minus 63 degrees Celsius) and exposure to ultraviolet light, gamma rays and high-energy protons mimicking the constant bombardment of Mars by solar ultraviolet light and cosmic radiation sleeting down from space.

After the bacteria and fungi had been exposed to various radiation levels in the experiment, Daly's team measured how much manganese antioxidants had accumulated in the cells of the microbes. Manganese antioxidants form as a result of radiation exposure, and the more that form, the more radiation the microbes can resist. Conan the Bacterium was the clear winner. The researchers found that Conan the Bacterium could absorb as much as 28,000 times more radiation than what a human can survive. This measurement allowed Daly's team to estimate how long the microbe could survive at different depths on Mars. Previous experiments, in which Conan the Bacterium had been suspended in liquid water and subjected to radiation like that found on Mars, had indicated that the microbe could survive below the surface of Mars for 1.2 million years.

However, the new tests, in which the microbe was frozen and dried out to mimic the cold and dry conditions on Mars, suggested that Conan the Bacterium would be able to survive 280 million years on Mars if buried at a depth of 33 feet. This lifespan is reduced to 1.5 million years if buried just 4 inches (10 centimeters) below the surface, and just a few hours on the surface, which is bathed in ultraviolet light. [...] The research also determined why Conan the Bacterium is so resistant to radiation. The scientists found that chromosomes and plasmids, which carry genetic information, in the microbe's cells are linked together, which keeps these structures aligned and prevents irradiated cells from breaking down until they can be repaired. "Although Deinococcus radiodurans buried in the Martian subsurface could not survive dormant for the estimated 2 to 2.5 billion years since flowing water disappeared on Mars, such Martian environments are regularly altered and melted by meteorite impacts," he said in a statement. "We suggest that periodic melting could allow intermittent repopulation and dispersal."

The findings were detailed in the journal Astrobiology.
