fahrbot-bot shares a report from Engadget: Becoming an astronaut requires perfect 20/20 vision, but unfortunately, the effects of space can cause astronauts to return to Earth with degraded eyesight. Now, researchers from UT Southwestern Medical Center have developed a sleeping bag that that could prevent or reduce those problems by effectively sucking fluid out of astronauts' heads. More than half of NASA astronauts that went to the International Space Station (ISS) for more than six months have developed vision problems to varying degrees. In one case, astronaut John Philips returned from a six month stint about the ISS in 2005 with his vision reduced from 20/20 to 20/100, as the BBC reported.

Fluids tend to accumulate in the head when you sleep, but on Earth, gravity pulls them back down into the body when you get up. In the low gravity of space, though, more than a half gallon of fluid collects in the head. That in turn applies pressure to the eyeball, causing flattening that can lead to vision impairment -- a disorder called spaceflight-associated neuro-ocular syndrome, or SANS. To combat SANS, researchers collaborated with outdoor gear manufacturer REI to develop a sleeping bag that fits around the waist, enclosing the lower body. A vacuum cleaner-like suction device is then activated that draws fluid toward the feet, preventing it from accumulating in the head. Around a dozen people volunteered to test the technology, and the results were positive.

"The Federal Aviation Administration said on Friday that it was ending a program that awarded small gold pins called 'Commercial Space Astronaut Wings' to certain people who flew to space on private spacecraft," reports the New York Times. (Alternate URL here.) But before the program officially retires in January, all who applied for the gold wings after flying to space this year will still receive them, the agency said.

That means Mr. Bezos, the billionaire founder of Amazon who rode a rocket with his space company, Blue Origin, to the edge of space in July, will be considered a commercial astronaut. So will Richard Branson, the founder of the space tourism firm Virgin Galactic who flew his own company's rocket plane to space in the same month. William Shatner, the Star Trek star who flew with Blue Origin to the edge of space in October, will also receive astronaut wings to go with his Starfleet paraphernalia. Twelve other people were also added to the federal agency's list of wing recipients on Friday [bringing the list up to 30 people].

The changes will help the F.A.A. avoid the potentially awkward position of proclaiming that some space tourists are only passengers, not astronauts.

The Commercial Space Astronaut Wings Program was created by Patti Grace Smith, the first chief of the F.A.A.'s commercial space office, to promote the private development of human spaceflight — a mandate from a 1984 law that aimed to accelerate innovation of space vehicles. The program began handing out pins to qualified individuals in 2004, when Mike Melvill, a test pilot who flew the Scaled Composites SpaceShipOne plane, became its first recipient. To qualify for the commercial astronaut wings under the original guidelines, a person had to reach an altitude of at least 50 miles, the marker of space recognized by NASA and the U.S. Air Force, and be a member of the spacecraft's "flight crew..."

Although no one will receive the little gold pins after 2021, those who fly above 50 miles on an F.A.A.-licensed rocket will be honored in the agency's online database.

But future space tourists should not despair a lack of post-flight flair. Virgin Galactic, Blue Origin and SpaceX have each presented paying and guest passengers with custom-designed wings.
Or, as the Associated Press put it, "The FAA said Friday it's clipping its astronaut wings because too many people are now launching into space and it's getting out of the astronaut designation business entirely...." "The U.S. commercial human spaceflight industry has come a long way from conducting test flights to launching paying customers into space," the FAA's associate administrator Wayne Monteith said in a statement. "Now it's time to offer recognition to a larger group of adventurers daring to go to space."

"To date, nearly 28,000 near-Earth asteroids have been found by survey telescopes that continually scan the night sky, adding new discoveries at a rate of about 3,000 per year..." according to an article from NASA:

"The first version of Sentry was a very capable system that was in operation for almost 20 years," said Javier Roa Vicens, who led the development of Sentry-II while working at JPL as a navigation engineer and recently moved to SpaceX. "It was based on some very smart mathematics: In under an hour, you could reliably get the impact probability for a newly discovered asteroid over the next 100 years — an incredible feat."
But RockDoctor (Slashdot reader #15,477), summarizes some new changes: For nearly 20 years, newly discovered asteroids had orbital predictions processed by a system called "Sentry", resulting in quick estimates on the impact risk they represent with Earth. Generally this has worked well, but several things in the future required updates, and a new system adds a number of useful features too.

The coming wave of big survey telescopes which will check the whole sky every few days is going to greatly increase the number of discoveries. That requires streamlining of the overall system to improve processing speed. The new system can also automatically incorporate factors which previously required manual intervention to calculate, particularly the effect of asteroid rotation creating non-gravitational forces on a new discovery's future orbit. Objects like asteroid Bennu (recently subject of a sampling mission) had significant uncertainty on their future path because of these effects. That doesn't mean that Bennu can possibly hit us in the next few centuries, but it became harder to say over the next few millennia. As NASA puts it:

Popular culture often depicts asteroids as chaotic objects that zoom haphazardly around our solar system, changing course unpredictably and threatening our planet without a moment's notice. This is not the reality. Asteroids are extremely predictable celestial bodies that obey the laws of physics and follow knowable orbital paths around the Sun.

But sometimes, those paths can come very close to Earth's future position and, because of small uncertainties in the asteroids' positions, a future Earth impact cannot be completely ruled out. So, astronomers use sophisticated impact monitoring software to automatically calculate the impact risk....

[T]he researchers have made the impact monitoring system more robust, enabling NASA to confidently assess all potential impacts with odds as low as a few chances in 10 million.


The article includes videos explaining the future uncertainties on the orbits of potentially hazardous asteroids Bennu and Apophis.

Blue Origin successfully completed a 10-minute suborbital spaceflight this morning.

But with SpaceX, Virgin Galactic, and the space agencies of Russia and China, Blue Origin also helped humanity achieve another milestone Saturday. The Washington Post explains how it will push us far past a record set in 1985 when America's space shuttle made nine flights into space: Saturday's launch will be the 13th human spaceflight of the year, two more than in 1985, when NASA carried out those nine shuttle flights, and the Russian Soyuz vehicle carried astronauts on two launches.

All of those flights reached orbit, while several of the flights this year barely scratched the edge of space in relatively short suborbital jaunts. Still, this year is "the busiest year in human spaceflight," Jennifer Levasseur, a curator at the National Air and Space Museum in Washington, said in an interview. "We're entering a new phase of activity that we've never, frankly, seen before. And it creates a lot of excitement."

Saturday's Blue Origin flight will also carry Dylan Taylor, chairman and CEO of space exploration firm Voyager Space; Evan Dick, an investor; Lane and Cameron Bess, the first parent-child pair to fly to space; and Laura Shepard Churchley, a daughter of Alan Shepard, the first American to go to space...

China, which is building a space station in low Earth orbit, flew two crewed missions this year, and Russia has flown three, including the flight this week. The flurry of activity is reminiscent of 1985, Levasseur said, a time when NASA was optimistic that it would fly dozens of times a year, carrying all sorts of people to space.
The Post ultimately calls 2021 "one of the most remarkable years for human spaceflight."

A brand-new space telescope will soon reveal a hidden vision of the cosmos, potentially transforming our understanding of black holes, supernovas and even the nature of the universe itself. No, not that one. From a report: Much attention is being devoted this month to the James Webb Space Telescope, from NASA and the European Space Agency, which is set to launch on Dec. 22. But a more exclusive cadre of astronomers watched excitedly on Thursday during the trip to space of a smaller, but also transformative, observatory. NASA launched the Imaging X-ray Polarimetry Explorer, or IXPE mission, on a SpaceX Falcon 9 rocket from Kennedy Space Center in Florida at 1 a.m. Eastern. The spacecraft cost a mere $188 million, compared with the James Webb's mammoth budget of $9.7 billion, and is expected to demonstrate a new form of astronomy. It will, for the first time, perform imaging X-ray polarimetry in orbit, a technique that could offer astronomers insights that no other telescope can match.

"It's giving us information about some of the most bizarre and exciting objects in space," said Thomas Zurbuchen, the associate administrator of NASA's science mission directorate. IXPE (pronounced by the mission team as "ix-pee") was placed into an orbit 340 miles above Earth after its launch. The telescope will spend several weeks there deploying its scientific instruments and testing its equipment, then begin its two-year mission. X-rays are a useful way to observe the universe. Emitted from extremely energetic objects, they allow astronomers to probe events -- superheated jets near black holes or explosions of stars, for example -- in a way other wavelengths, such as visible light, cannot. But X-rays can be studied only from space because they are mostly absorbed by Earth's atmosphere. A variety of dedicated X-ray space telescopes and instruments have launched to orbit, most notably NASA's Chandra X-ray and ESA's XMM-Newton observatories, which both launched in 1999. With spacecraft like these, scientists have unveiled the birthplaces of stars inside gaseous nebulas and mapped the spread of dark matter in clusters of galaxies, among other pioneering work.

Reeses writes: The Debrief just reported that DARPA just "accidentally" created the world's first warp bubble. From the article:

Warp drive pioneer and former NASA warp drive specialist Dr. Harold G "Sonny" White has reported the successful manifestation of an actual, real-world "Warp Bubble." And, according to White, this first of its kind breakthrough by his Limitless Space Institute (LSI) team sets a new starting point for those trying to manufacture a full-sized, warp-capable spacecraft.

There's also a video of the announcement, The Very First Warp-Bubble Created by DARPA Funded Team.

The hunting grounds are apparently widening for one of "nature's most effective predators" reports the New York Times, warning of "potentially significant consequences for animals up and down the food chain...."

"As sea ice has receded, killer whales — which are actually dolphins — are now venturing to parts of the sea that were once inaccessible, and spending more time in places they were once seen only sporadically," according to data presented by research scientist Brynn Kimber (who works in the National Oceanic and Atmospheric Administration's Marine Mammal Laboratory). Arctic sea ice has declined significantly in the four decades since satellite monitoring began. Roughly 75 percent of ice volume disappeared in the last 15 years alone, and the remaining ice is thinner and of poorer quality, said Amy Willoughby, a marine mammal biologist with NOAA's Alaska Fisheries Science Center. The loss of ice coupled with warming waters and atmospheric temperatures has affected every level of the Arctic ecosystem. Large mammals like polar bears have struggled to navigate shrinking habitats, while the marine algae at the base of the Arctic food chain blooms sooner and more abundantly than ever before.

In recent years, scientists have noticed similar upheaval in the behavior of the region's marine mammals. Orca are feasting more often on bowhead whales. Scientists and Indigenous Arctic communities have noted a growing number of bowhead whale carcasses in the northeastern Chukchi and western Beaufort seas with signs of orca attack....

"Killer whales are really intelligent," said Cory Matthews, a research scientist with the Arctic region of Fisheries and Oceans Canada. "They consume really fast. If a new area opens up, they can get in there maybe within the next year and exploit a prey population that could be perhaps really slow to respond to those changes."

Smithsonian magazine explores the many Mars simulation facilities around the world, including the Mars Desert Research Station — which is located in Utah, four hours south of Salt Lake City, "but everyone spoke and acted as though they were actually on Mars." A group of six people lived in a two-story cylindrical building. The commander, a former member of the Army National Guard, kept the participants on a strict schedule of fixing electrical systems, taking inventory, tidying up the facilities and sampling the soil. Everyone was assigned a special role: [photographer] Klos' was to prepare reports to share with the public. The health safety officer kept tabs on the crew's well-being, and the engineer monitored levels of carbon dioxide and solar power. Before stepping outside in a spacesuit, Klos and the others had to get permission from mission control back on "Earth" (actually a coordinator stationed in a nearby town). That person would send information about the winds and weather, and determine how long each person could stay outside the base. Sometimes dust storms rolled in, cutting off the solar power supply just as they would on Mars...

There are about a dozen such habitats around the globe, hosting simulations that run anywhere from two weeks to a full year. One of these is run by NASA's Human Research Program at the Johnson Space Center in Houston. But other facilities are funded by private organizations. The Mars Society, established by Brooklyn-born aerospace engineer Robert Zubrin, operates the habitat in Utah, where Klos returned for another mission in 2017, and another in the Canadian Arctic. Klos also took part in a mission at the Hawaii Space Exploration Analog and Simulation, or HI-SEAS. The facility is run by the International MoonBase Alliance, a group founded by the Dutch entrepreneur Henk Rogers.

HI-SEAS is located on Hawaii's big island at 8,200 feet above sea level, on top of the active volcano Mauna Loa. NASA's Goddard Space Flight Center is collaborating with the facility to gather information about volcanic caves and the microbes that live in those Mars-like conditions. HI-SEAS is also studying the limitations of doing that kind of work while wearing heavy spacesuits. It's hard enough for astronauts to hold a screwdriver in a gloved hand while repairing the International Space Station, but if people are going to be clambering on Martian rocks looking for microbes, they'll need the right gear.
The article notes these missions "are open to people who have no background in science, engineering or astronaut training. After all, the goal is to send ordinary folks into space, so it's worth finding out whether ordinary folks can coexist in Mars-like conditions here on Earth." (Some are even recruited off the internet.) "Sometimes people make the critique that we're role-playing too much," the photographer tells the magazine. "But the goal is to really live the way people are going to live on Mars so scientists can figure out how to make it work when we get there."

And the article also points out that "The data we're gathering now about surviving on solar power, conserving water and growing plants in arid conditions could be useful here at home as our climate changes."

"The International Space Station dodged a fragment of a decades-old rocket body early Friday morning," reports Space.com, "continuing a stretch of space debris threats to the orbiting laboratory." On Friday (Dec. 3) at around 3 a.m. EST (0800 GMT), a Russian cargo ship docked to the International Space Station fired for a little under three minutes to lower the facility's orbit and ensure that it would pass safely by the debris, according to statements from NASA and its Russian counterpart, Roscosmos....

In a tweet posted on Wednesday (Dec. 1), Roscosmos flagged the risk posed by the rocket fragment, which it said was estimated to pass as close as 3.4 miles (5.4 kilometers) to the space station. Just the day before the alert was posted, on Tuesday (Nov. 30), NASA had been forced to delay a spacewalk scheduled for later in the day due to concerns about debris. The agency has not specified what that debris represents, but NASA astronaut Thomas Marshburn and Kayla Barron were able to conduct their excursion on Thursday (Dec. 2).
NASA identified Friday's debris was part of a 1994 U.S. Pegasus rocket, which later broke up in space 1996.

Just two days after officially (and quietly) confirming that it intends to replace the International Space Station with a commercial station by 2030, NASA has awarded over $400 million in agreements to three companies to further develop private station plans. TechCrunch reports: The three companies, which received the awards under the agency's Commercial low Earth orbit (LEO) Destinations program, are: Nanoracks for $160 million; Blue Origin for $130 million; and Northrop Grumman for $125.6 million. NASA received eleven proposals in total, director of commercial spaceflight Phil McAlister said Thursday. He added that of the three chosen proposals, there was a diversity of technical concepts and a variety of logistical and launch vehicle options offered. "This diversity not only enhances the likelihood of success of NASA strategy, but it also leads to a high degree of innovation, which is critical in most commercial space endeavors," he said.

The three companies have already released a handful of details about their proposals. Blue Origin is calling its station concept "Orbital Reef," and it is designing it with Boeing, Sierra Space and others. The team said it wants to launch the station in 2027. Meanwhile, Nanoracks is calling its station, which is being developed with its parent company Voyager Space and aerospace prime Lockheed Martin, "Starlab." While Northrop didn't give its station proposal a flashy name, it's working with Dynetics to deliver a modular design based around its Cygnus spacecraft.

These substantial awards mark the first phase of a two-phase process as NASA seeks to ensure that there will be no gap between the retirement of the ISS and the introduction of a new station. NASA has repeatedly stressed, both to Congress and more recently in a report by the Office of Inspector General, that the overall success of the development of a thriving economy in LEO is dependent upon avoiding this gap. "If there is no habitable commercial destination in low Earth orbit after the ISS is decommissioned, NASA will be unable to conduct microgravity health research and technology demonstrations needed for long-duration human exploration missions to the Moon and Mars, significantly increasing the risk of -- or delaying -- those missions," the agency said in the report.

Today, Vice President Kamala Harris' office released a new framework for US space policy, detailing how the Biden administration plans to approach commercial, civil, and military space activity moving forward. From a report: Called the United States Space Priorities Framework, the document keeps many of the same space priorities from the previous administration but adds a new emphasis on using space to help combat climate change and investing in STEM education. The new framework comes ahead of today's National Space Council meeting, the first one to be held under the Biden administration. Harris, who chairs the National Space Council, will convene the policy advisory group at the United States Institute of Peace in Washington, DC, at 1:30PM ET today.

[...] When it comes to space, the Biden administration is carrying forward many of the priorities set by the Trump administration. Notably, NASA's ambitious Artemis program, which was solidified under Trump, is still a major focus under Biden. And plenty of the topics discussed under Pence's Space Council are included in the new framework released by Harris. A few of the key points include maintaining US leadership in space by sending humans back to the Moon and exploring the Solar System with robotic spacecraft, fostering a competitive, regulatory environment for space companies, and defending against security threats in space while strengthening our space assets. In the biggest break from the previous administration, there looks to be a renewed focus on using space in the fight against climate change. In the new framework, the administration pledges to invest in satellites that can observe Earth from space, helping scientists better understand our changing climate. "Open dissemination of Earth observation data will support both domestic and international efforts to address the climate crisis," the document states. To further drive home this new emphasis on climate research from space, President Biden plans to sign a new Executive Order today that will add five new members to the National Space Council, including the Secretaries of Education, Labor, Agriculture, and the Interior, but also notably the National Climate Advisor.

Nasa has postponed a planned spacewalk outside the International Space Station due to flying "debris," two weeks after Russia blew up one of its own satellites in a missile test that created clouds of zooming shrapnel in orbit. From a report: Washington's space agency did not mention the Russian test in its announcement, but a Nasa official had warned a day earlier of a slightly elevated risk to astronauts due to the 14 November incident. The strike generated thousands of pieces of "space junk" that are now hurling around the Earth at about 17,000 mph (27,400km/h) -- much faster than the speed of a bullet. At that velocity, even tiny flecks of paint can damage spacecraft, with spacesuits even more vulnerable.

On Tuesday, about five hours before the astronauts Thomas Marshburn and Kayla Barron were due to venture outside the space station, Nasa said on Twitter that the spacewalk to fix a failed antenna had been cancelled. "Nasa received a debris notification for the space station. Due to the lack of opportunity to properly assess the risk it could pose to the astronauts, teams have decided to delay the 30 November spacewalk until more information is available," it tweeted. Moscow has said its test to destroy its own spacecraft, Tselina-D, which had been in orbit since 1982, was successful and the debris posed no "threat to space activity."

Hmmmmmm writes: China is developing a powerful nuclear reactor for its moon and Mars missions, according to researchers involved in the project. The reactor can generate one megawatt of electric power, 100 times more powerful than a similar device Nasa plans to put on the surface of the moon by 2030. The project was launched with funding from the central government in 2019. Although technical details and the launch date were not revealed, the engineering design of a prototype machine was completed recently and some critical components have been built, two scientists who took part in the project confirmed to the South China Morning Post this week.

To China, this is an ambitious project with unprecedented challenges. The only publicly known nuclear device it has sent into space is a tiny radioactive battery on Yutu 2, the first rover to land on the far side of the moon in 2019. That device could only generate a few watts of heat to help the rover during long lunar nights. Chemical fuel and solar panels will no longer be enough to meet the demands of human space exploration, which is expected to expand significantly with human settlements on the moon or Mars on the agenda, according to the Chinese researchers. "Nuclear power is the most hopeful solution. Other nations have launched some ambitious plans. China cannot afford the cost of losing this race," said one researcher with the Chinese Academy of Sciences who asked not to be named as they were not authorised to speak to the media.

If all goes as planned, a SpaceX Falcon 9 rocket carrying the Double Asteroid Redirection Test (DART) will launch early Wednesday morning "to test whether slamming a spacecraft into an asteroid can nudge it into a different trajectory," reports The New York Times. "Results from the test, if successful, will come in handy if NASA and other space agencies ever need to deflect an asteroid to save Earth and avert a catastrophic impact." From the report: The DART spacecraft is scheduled to lift off atop a SpaceX Falcon 9 rocket on Wednesday at 1:20 a.m. Eastern time (or 10:20 p.m. local time) from the Vandenberg Space Force Base in California. NASA plans to host a livestream of the launch on its YouTube channel starting at 12:30 a.m. on Wednesday. If bad weather around the Vandenberg launch site prompts a delay, the next opportunity for liftoff would be about 24 hours later.

After launching to space, the spacecraft will make nearly one full orbit around the sun before it crosses paths with Dimorphos, a football-field-size asteroid that closely orbits a bigger asteroid, called Didymos, every 11 hours and 55 minutes. Astronomers call those two asteroids a binary system, where one is a mini-moon to the other. Together, the two asteroids make one full orbit around the sun every two years. Dimorphos poses no threat to Earth, and the mission is essentially target practice. DART's impact will happen in late September or early October next year, when the binary asteroids are at their closest point to Earth, roughly 6.8 million miles away.

Four hours before impact, the DART spacecraft, formally called a kinetic impactor, will autonomously steer itself straight toward Dimorphos for a head-on collision at 15,000 miles per hour. An onboard camera will capture and send back photos to Earth in real time until 20 seconds before impact. A tiny satellite from the Italian Space Agency, deployed 10 days before the impact, will come as close as 34 miles from the asteroid to snap images every six seconds in the moments before and after DART's impact.

A short update on the projected launch date of the $10 billion James Webb Space Telescope came out of NASA on Monday, and it wasn't exactly a heart-warming missive. From a report: The large, space-based telescope's "no earlier than" launch date will slip from December 18 to at least December 22 after an "incident" occurred during processing operations at the launch site in Kourou, French Guiana. That is where the telescope will launch on an Ariane 5 rocket provided by the European Space Agency. "Technicians were preparing to attach Webb to the launch vehicle adapter, which is used to integrate the observatory with the upper stage of the Ariane 5 rocket," NASA said in a blog post. "A sudden, unplanned release of a clamp band -- which secures Webb to the launch vehicle adapter -- caused a vibration throughout the observatory."

"An Australian company is part of an international effort to recycle dangerous space junk into rocket fuel — in space," reports the Guardian.

Slashdot reader votsalo shared their report (which also looks at some of the other companies working on the problem of space debris). South Australian company Neumann Space has developed an "in-space electric propulsion system" that can be used in low Earth orbit to extend the missions of spacecraft, move satellites, or de-orbit them. Now Neumann is working on a plan with three other companies to turn space junk into fuel for that propulsion system... Another U.S. company, Cislunar, is developing a space foundry to melt debris into metal rods. And Neumann Space's propulsion system can use those metal rods as fuel — their system ionises the metal which then creates thrust to move objects around orbit.

Chief executive officer Herve Astier said when Neumann was approached to be part of a supply chain to melt metal in space, he thought it was a futuristic plan, and would not be "as easy as it looks".

"But they got a grant from NASA so we built a prototype and it works," he said...

Astier says it is still futuristic, but now he can see that it's possible. "A lot of people are putting money into debris. Often it's to take it down into the atmosphere and burn it up. But if it's there and you can capture it and reuse it, it makes sense from a business perspective, because you're not shipping it up there," he said.

"It's like developing a gas station in space."

An anonymous reader quotes a report from Phys.org: NASA and the nation's top federal nuclear research lab on Friday put out a request for proposals for a fission surface power system. NASA is collaborating with the U.S. Department of Energy's Idaho National Laboratory to establish a sun-independent power source for missions to the moon by the end of the decade. If successful in supporting a sustained human presence on the moon, the next objective would be Mars. NASA says fission surface power could provide sustained, abundant power no matter the environmental conditions on the moon or Mars. The reactor would be built on Earth and then sent to the moon.

Submitted plans for the fission surface power system should include a uranium-fueled reactor core, a system to convert the nuclear power into usable energy, a thermal management system to keep the reactor cool, and a distribution system providing no less than 40 kilowatts of continuous electric power for 10 years in the lunar environment. Some other requirements include that it be capable of turning itself off and on without human help, that it be able to operate from the deck of a lunar lander, and that it can be removed from the lander and run on a mobile system and be transported to a different lunar site for operation. Additionally, when launched from Earth to the moon, it should fit inside a 12-foot (4-meter) diameter cylinder that's 18 feet (6 meters) long. It should not weigh more than 13,200 pounds (6,000 kilograms). The proposal requests are for an initial system design and must be submitted by Feb. 19.

Satellite trackers have been working overtime to figure out just how much dangerous debris Russia created when it destroyed one of its own satellites early Monday -- and the picture they've painted looks bleak. Multiple visual simulations of Russia's anti-satellite, or ASAT, test show a widespread cloud of debris that will likely menace other objects in orbit for years. The Verge reports: It's going to take weeks or even months to fully understand just how bad the situation is, but early visualizations of the ASAT test created by satellite trackers show an extensive trail of space debris left in the wake of the breakup. The fragments appear like a dotted snake in orbit, stretching out and moving in roughly the same direction that Kosmos 1408 used to move around Earth. And there's one thing the visualizers agree on: this snake of debris isn't going anywhere anytime soon. "There will be some potential collision risk to most satellites in [low Earth orbit] from the fragmentation of Cosmos 1408 over the next few years to decades," LeoLabs, a private space tracking company in the US, wrote in a blog post.

Two visualizations created by the European Union's Space Surveillance and Tracking (SST) network and space software company AGI reveal what likely happened in the first moment of impact when Russia's missile intercepted Kosmos 1408. They both show how the debris cloud grew instantly and spread throughout space. AGI's simulation also shows just how close the cloud comes to intersecting with the International Space Station, validating NASA's concerns and the agency's decision to have the astronauts shelter in place.

Another visualization created by Hugh Lewis, a professor of engineering at the University of Southampton specializing in space debris, shows just how widely the debris from Kosmos 1408 has spread out in space. Lewis explains that when Russia's missile hit the satellite, each of the fragments that were created got a little kick, sending them to higher and lower altitudes. Each piece is moving at a different speed depending on the height of its orbit. Lewis says that the cloud will continue to morph over time. The debris fragments in the lower orbits will fall to Earth and out of orbit more quickly, while the ones in higher orbits will stay in space much longer.

NASA has now released the most detailed footage yet of Ingenuity in flight. Gizmodo reports: The two videos were taken during the rotorcraft's 13th flight, which took place on September 4. The 16-second flight saw Ingenuity travel nearly 700 feet horizontally, at an altitude of 26 feet. The Perseverance rover recorded the rotorcraft's maneuvers using its two-camera Mastcam-Z, from a distance of about 1,000 feet away.

"The value of Mastcam-Z really shines through with these video clips," Justin Maki, deputy principal investigator for the Mastcam-Z instrument at NASA's Jet Propulsion Laboratory in Southern California, said in a NASA press release. "Even at 300 meters [984 feet] away, we get a magnificent closeup of takeoff and landing through Mastcam-Z's âright eye.' And while the helicopter is little more than a speck in the wide view taken through the 'left eye,' it gives viewers a good feel for the size of the environment that Ingenuity is exploring."

Recently, the scientists at NASA had to program Ingenuity to move a little faster, to compensate for the thinner atmosphere on Mars as the planet's seasons change. The helicopter's navigation system is automated and uses artificial intelligence to constantly measure and correct for environmental variables like wind speed and the level of the ground below it. "It's awesome to actually get to see this [automatic correction] occur," said Havard Grip, Ingenuity's chief pilot, in the same release. "It reinforces the accuracy of our modeling and our understanding of how to best operate Ingenuity."

An anonymous reader quotes a report from CNBC: Elon Musk on Wednesday said SpaceX is "hoping" to launch the first orbital flight test of its mammoth Starship rocket in January, a schedule that depends on testing and regulatory approval. "We'll do a bunch of tests in December and hopefully launch in January," Musk said, speaking at a meeting of the National Academies of Sciences, Engineering, and Medicine Space Studies Board.

The company's next major step in developing Starship is launching to orbit. First, the company needs a launch license from the Federal Aviation Administration for the mission, with the regulator expecting to complete a key environmental assessment by the end of this year. Musk noted that he wasn't sure if Starship would successfully reach orbit on the first try, but emphasized that he is "confident" that the rocket will get to space in 2022. "We intend to have a high flight rate next year," Musk said.

SpaceX aims to launch as many as a dozen Starship test flights next year, he said, to complete the "test flight program" and move to launching "real payloads in 2023." He stressed that creating a mass production line for Starship is crucial to the program's long-term goals, noting that the current "biggest constraint" on rocket manufacturing is how fast the company can build the Raptor engines needed for Starship. "I think, in order for life to become multiplanetary, we'll need maybe 1,000 ships or something like that," Musk said. "The overarching goal of SpaceX has been to advance space technology such that humanity can become a multi-planet species and, ultimately, a spacefaring civilization." SpaceX received a $2.9 billion contract from NASA to develop Starship for delivering astronauts to the moon's surface, but Musk said the company is "not assuming any international collaboration" or external funding for the rocket program. "[Starship] is at least 90% internally funded thus far," Musk said.
