In 2021, a team of hologram doctors was "holoported" to space to visit astronauts living aboard the International Space Station, NASA has revealed in a new post. Space.com reports: The hologram teams, led by NASA flight surgeon Dr. Josef Schmid and Fernando De La Pena Llaca, CEO of software provider Aexa Aerospace, were the first humans to ever be "holoported" from Earth to space. "This is completely new manner of human communication across vast distances," Schmid said in the statement. "Furthermore, it is a brand-new way of human exploration, where our human entity is able to travel off the planet. Our physical body is not there, but our human entity absolutely is there."

"It doesn't matter that the space station is traveling 17,500 mph [28,000 kilometers per hour] and in constant motion in orbit 250 miles [400 km] above Earth, the astronaut can come back three minutes or three weeks later and with the system running, we will be there in that spot, live on the space station," Schmid added. The medical teams holoported to the station on Oct. 8. Using the Microsoft Hololens Kinect camera and a personal computer with custom Aexa software, European Space Agency astronaut Thomas Pesquet, who was on board the station at that time, had a holo-conversation with Schmid and De La Pena's teams. The holograms of the doctors were visible live in the middle of the space station.

So how did it work? The "holoportation" technology that enabled this event works using specialized image capture technology that reconstructs, compresses and transmits live 3D models of people. This technology couples with the HoloLens, a self-described "mixed reality headset" that combines sensors, optics and holographic processing tech to allow the wearer to see the hologram images or even enter a "virtual world." With the two systems combined, users in orbit can not only see hologram participants, but can also hear and interact with them. The technology is not new, but has never been used in an environment this challenging with users so far apart.

A SpaceX Crew Dragon safely delivered four private astronauts to the International Space Station this past Saturday. Gizmodo reports: SpaceX capsule Endeavor reached the ISS at 8:20 a.m. EDT on Saturday, April 9, following a nearly 21-hour journey. The crew of the Ax-1 mission -- Michael Lopez-Alegria, Larry Connor, Eytan Stibbe, and Mark Pathy -- launched atop a Falcon 9 rocket on Thursday from Kennedy Space Center in Florida. The ISS is currently orbiting at a height of 260 miles (418 km) above Earth. The docking would've happened 45 minutes earlier, had it not been for a problem having to do with ISS crew members not being able to receive video from the Crew Dragon's center line camera. Ground controllers remedied the problem by routing video from a SpaceX ground station, according to NASA.

The four crew members will stay on the orbital outpost for eight days, where they will perform some 25 experiments having to do with science, education, and commercial activities. Axiom Space is aiming to build the world's first fully commercial space station, the construction of which is slated to begin at the ISS in late 2024. The Ax-1 mission represents an important milestone in the ongoing commercialization of low Earth orbit. [...] Axiom said the first day was mostly about preparing equipment for what will be a very busy week. The team has just 100 hours to complete their respective tasks.

Loren Grush writes via The Verge: Tomorrow morning, SpaceX is set to launch yet another crew of four to the International Space Station from Florida -- but unlike most of the company's passenger flights, this new crop of flyers won't include any current NASA astronauts. All four members of the crew are civilians, flying with a commercial aerospace company called Axiom Space. Their flight will mark the first time a completely private crew has visited the ISS. It's a new type of human spaceflight mission and one that comes with a hefty price tag for its participants. Three of the four flyers have each paid a reported $55 million for their seats on SpaceX's crew capsule, called the Crew Dragon. The trio of novice spacefarers includes Canadian investor Mark Pathy, American real estate investor Larry Connor, and former Israeli Air Force pilot Eytan Stibbe. The commander of the trip is a spaceflight veteran: Michael Lopez-Alegria, a former NASA astronaut who has flown four missions to space and now serves as a vice president of Axiom.

Their mission, called Ax-1, is the latest in an emerging trend of completely private astronaut flights to orbit. [...] Axiom -- which strives to create a fleet of commercial space stations -- has arranged for three additional private crew missions to the ISS, just like Ax-1, to gear up for the creation of its first station. The company's goal is to "make space more accessible to everyone." "This really does represent the first step where a bunch of individuals who want to do something meaningful in low Earth orbit -- that aren't members of a government -- are able to take this opportunity," Mike Suffredini, Axiom's CEO and the former program manager of the ISS at NASA, said during a press conference. Though, until costs come down, such individuals will need a fat wallet.

Slashdot reader alaskana98 writes: In what has become a stubborn sibling to the 'Face on Mars' phenomenon, the legend of the Dark Knight alien satellite has persisted for years and is the fascinating story of a seemingly mundane NASA photo tied together with reports of seemingly mysterious radio waves captured in the early days of radio, all combining to make the ultimate space conspiracy theory.

It goes something like this — an ancient alien space probe, dubbed the 'Dark Knight, has been long orbiting Earth and covertly monitoring its blissfully unaware inhabitants for mysterious purposes for roughly 10,000 years. Flash forward to the 1899, where technological pioneer Nikola Tesla, while experimenting with radio technology in his Colorado laboratory supposedly captured mysterious emanations from an unearthly object. Later in the 1920's, Norwegian engineer Jørgen Hals found that radio signals he transmitted were being echoed back to him a few seconds later, something called 'long delayed echoes' — still unexplained to this day. It has been proposed that these echoes were signals being relayed back to earth by something called a 'Bracewell Probe', a hypothetical automated spacecraft sent out with the goal of making contact with other intelligent species.

Flash forward to 1998, an unassuming photo from the STS-88 mission in 1998 to attach the U.S. module to the Russian portion of the ISS captured a tantalizing glimpse of an unnaturally geometric shape menacingly loitering toward the bottom of the frame. To true believers, this was evidence of an ancient probe keeping tabs on the earthly locals. Combined, these disparate events swirl together to create the stuff of dreams for the ardent conspiracy theorist and even the causal sci-fi buff. Ultimately, the object in the STS photo was most likely a thermal cover. The radio waves Tesla heard? Likely natural radio emisions of a natural or terestial source.

Space.com took a deep dive into this myth and explored how it — and the - dark knight myth has taken a hold on the imaginations of those who find themselves peering out into the inky blackness of the night and wonder to themselves "are we being watched from above"?

"Russia's Roscosmos will stop working with NASA and other western space agencies on the International Space Station," reports Engadget: On early Saturday morning, Roscosmos director Dmitry Rogozin slammed international sanctions against Russia and said normal cooperation between the space agency and its western counterparts would only be possible after they were lifted.... Rogozin said Roscosmos would submit proposals on ending its work with NASA and other international space agencies to Russian authorities.

It's unclear how the decision would affect the space station. The ISS is not owned by any single country. The US, European Union, Russia, Canada and Japan operate the station through a cooperative agreement between the countries. Roscosmos, however, is critical to the ISS. The Russian Orbital Segment handles guidance control for the entire station....

The ISS isn't the first joint space program to see its future thrown into uncertainty due to rising tensions between the West and Russia. In March, Roscosmos said it would not ferry OneWeb's internet satellites to space until the UK government sold its stake in the company. That same month, the European Space Agency announced it was suspending its joint ExoMars mission with Roscosmos.
But in the middle of all this, "There are currently seven astronauts onboard the ISS — three Russian cosmonauts, three NASA astronauts and one German-born ESA astronaut, Matthias Maurer..." reports UPI: The three Russian cosmonauts are Sergey Korsakov, Oleg Artemyev and Denis Matveev. It was not immediately clear how the suspension of cooperation would impact the cosmonauts at the ISS.

Artemyev has expressed support for Russia and its decision to invade Ukraine in a statement made last month after he boarded the space station in a yellow and blue uniform, the colors of the Ukrainian flag. "There is no need to look for secret signs and symbols in our uniform. Color is just color," he said. "Despite the fact that we are in space, we are together with our president and people!"

Despite the United States and Russia's deteriorating relationship here on Earth, Russia is still considering extending its participation on the International Space Station through 2030, according to NASA. However, it could be a few months before there is a solid update on Russia's official stance. From a report: NASA and Russia's state space corporation, Roscosmos, have been the two largest partners on the International Space Station for the last three decades. The two organizations have agreed to work together on the ISS through 2024, but at the end of last year, the Biden administration announced its intentions to extend the space station program through 2030. Russia has not formally agreed to the extension yet.

Roscosmos's participation in the extension started to seem unlikely after Russia invaded Ukraine in February. In response to the war, the United States sanctioned Russia's major industries, which triggered outrage from the head of Roscosmos, Dmitry Rogozin. On Twitter, Rogozin made wild threats about the future of the ISS, insinuating that the station could come crashing down on the United States if Russia withdrew prematurely from the program. He has also hinted at revisiting the partnership with the US in light of the sanctions.

InfiniteZero shares a report from Space.com: Last Wednesday (March 23), NASA astronaut Raja Chari and the European Space Agency's Matthias Maurer spent nearly seven hours outside the International Space Station, performing a variety of maintenance work. Amazingly, astrophotographer Sebastian Voltmer managed to capture a snapshot of the spacewalk action from the ground -- and from Maurer's hometown of Sankt Wendel, Germany, no less. "I feel like I just made a once-in-a-lifetime image," Voltmer wrote at SpaceWeather.com, which featured the photo in its online gallery.

SpaceX has ended production of new Crew Dragon astronaut capsules, a company executive told Reuters, as Elon Musk's space transportation company heaps resources on its next-generation spaceship program. From the report: Capping the fleet at four Crew Dragons adds more urgency to the development of the astronaut capsule's eventual successor, Starship, SpaceX's moon and Mars rocket. Starship's debut launch has been delayed for months by engine development hurdles and regulatory reviews. It also poses new challenges as the company learns how to maintain a fleet and quickly fix unexpected problems without holding up a busy schedule of astronaut missions.

"We are finishing our final (capsule), but we still are manufacturing components, because we'll be refurbishing," SpaceX President Gwynne Shotwell told Reuters, confirming the plan to end Crew Dragon manufacturing. She added that SpaceX would retain the capability to build more capsules if a need arises in the future, but contended that "fleet management is key." Musk's business model is underpinned by reusable spacecraft, so it was inevitable the company would cease production at some point. But the timing was not known, nor was his strategy of using the existing fleet for its full backlog of missions. "Crew Dragon has flown five crews of government and private astronauts to space since 2020, when it flew its first pair of NASA astronauts and became the U.S. space agency's primary ride for getting humans to and from the International Space Station," notes Reuters.

Toshiba shareholders on Thursday voted down competing proposals -- one presented by management and the other backed by activist shareholders, leaving the future direction of the embattled Japanese conglomerate uncertain. From a report: Management's plan to spin off Toshiba's devices unit and the separate call to seek buyout offers had both failed to gain the required 50% of the vote. The untidy outcome ensures there will be no immediate end to a four-year scandal-filled battle between management and foreign activist hedge funds, while underscoring deep divisions among Toshiba shareholders. Opposition to Toshiba's plans to break up the company had been widespread and included proxy advisory firms, and its failure comes as no surprise. But the outlook for Singapore-based 3D Investment Partners' proposal that Toshiba solicit private equity buyout offers or a minority investment had been less clear cut. Although 3D and Toshiba's other top two shareholders had supported the quest for a buyout offer, proxy advisory firm Institutional Shareholder Services (ISS) had advised against it, saying the proposal "appears overly prescriptive and premature."

Three Russian cosmonauts arrived at the International Space Station last night for a six-month stay, writess the Times of London.

They were wearing flight suits "in the yellow and blue of the Ukrainian flag, in what appeared to be a daring statement against the war."

Space.com reports: Cosmonaut Oleg Artemyev, the Soyuz commander, was asked about the colors during a hatch-opening ceremony webcast by Russia's federal space agency Roscosmos. He responded (in Russian) that there was a surplus of yellow fabric in the warehouse, according to space exploration enthusiast Katya Pavlushchenko, who posted a Twitter thread about the exchange.

Not everybody's buying this answer, however. Some folks with knowledge of spaceflight procedures seem to think it could be a show of support for Ukraine, which Russia invaded on February 24.... There are other possible explanations for the flight suits as well. For example, multiple people on Twitter have pointed out that the colors are close to those of Bauman Moscow State Technical University, which Artemyev, Matveev and Korsakov all attended.

This is all just speculation; all we have to go on at the moment is Artemyev's cryptic response during the hatch-opening ceremony. Hopefully one of the cosmonauts will offer some more details in the not-too-distant future. None of the three newly arrived cosmonauts hails from Ukraine, by the way. Artemyev was born in present-day Latvia, Matveev is from St. Petersburg and Korsakov was born in what is now Kyrgyzstan.
Next month a SpaceX Dragon is expected to carry three millionaires to the Space Station for a week-long visit.

Former astronaut Scott Kelly said he is ending his feud with the head of Russia's space program after the National Aeronautics and Space Administration asked former astronauts to dial down criticism of their Russian counterparts. From a report: The dustup began when Roscosmos Director General Dmitry Rogozin and other Russian government entities published a series of social-media posts, including one video showing Russian cosmonauts abandoning the International Space Station and leaving behind U.S. astronaut Mark Vande Hei. Mr. Kelly, who spent nearly a year in 2015 and 2016 aboard the ISS, got into a heated exchange on Twitter last week with the Russian space chief over the series of posts. Now Mr. Kelly said he is ending the spat with Mr. Rogozin after NASA sent an email to former astronauts asking them to stop criticizing their Russian partners because it was hurting the mission aboard the ISS, an orbiting lab where American astronauts and Russian cosmonauts work side by side. "I respect their position. They have a tough job. I believe in NASA and what they do. I want to help them. I respect the person that sent it greatly," Mr. Kelly said in an interview. "I would say that if I was in their position, I would have done the same exact thing."

The US astronaut Mark Vande Hei has made it through nearly a year in space, but now faces what could be his trickiest assignment: riding a Russian capsule back to Earth in the midst of deepening tension between the two countries. From a report: Nasa insists Vande Hei's homecoming at the end of the month remains unchanged, even as Russia's invasion of Ukraine has resulted in canceled launches, broken contracts and an escalating war of words from the leader of the Russian Space Agency. Many worry Dmitry Rogozin is putting decades of peaceful partnership at risk, most notably at the International Space Station (ISS). Vande Hei, who on Tuesday will break the US single spaceflight record of 340 days, is due to leave with two Russians aboard a Soyuz capsule for touchdown in Kazakhstan on 30 March. He will have logged 355 days in space. The world record of 438 days belongs to Russia.

The retired Nasa astronaut Scott Kelly, America's record-holder until Tuesday, is among those sparring with Rogozin, a longtime ally of Vladimir Putin. Kelly has returned a medal to the Russian embassy in Washington but believes the two sides "can hold it together" in space. "We need an example set that two countries that historically have not been on the most friendly of terms, can still work somewhere peacefully. And that somewhere is the International Space Station. That's why we need to fight to keep it," Kelly said. Nasa wants to keep the space station running until 2030, as do the European, Japanese and Canadian space agencies. The Russians have not committed beyond the original end date of 2024 or so.

Ever since Russia invaded Ukraine, the fate of the International Space Station, which has 15 partner nations and is the crown jewel of unity in space between NASA and Russia, has been up in the air (figuratively, of course). What we do know is that there are no plans to abandon NASA astronaut Mark Vande Hei on the space station, despite a number of stories claiming otherwise. "Vande Hei is scheduled to return to Earth in a Soyuz capsule at the end of this month, landing in Kazakhstan," reports Ars Technica. "NASA officials are expected to be there to greet him and bring him back to the United States." Ars Technica sets the record straight and explains where these Russian "threats" originated: The source of this "news" appears to be a video published more than a week ago by a Kremlin-aligned publication, RIA Novosti. Roscosmos TV provided footage for the video, but in sharing it acknowledged that the video was a "joke." Now, this is an exceptionally poor joke given the tensions on Earth, but it is important to understand that sharing a video a week ago does not mean Russia is threatening to leave Vande Hei behind. Nothing has changed since the video was posted. Since the beginning of this crisis, NASA officials have said operations with Russian colleagues working on the space station have proceeded nominally. "Operations have not changed at all," one NASA source confirmed Friday. On Monday, NASA's manager of the International Space Program, Joel Montalbano, is scheduled to speak at a news conference about upcoming spacewalks. He likely will say something similar.

Additionally, Vande Hei could not be abandoned. At present there are three other Americans living on board the International Space Station -- Raja Chari, Kayla Barron, and Thomas Marshburn. There is also an allied astronaut, Matthias Maurer, from Germany. NASA has its own transportation to and from the station, so Vande Hei can be assured of a safe ride home whenever NASA wants. The status of the ISS partnership is subject to change, of course. It could do so quite quickly. Russia is doing horrible things in Ukraine, and the Western world has responded with harsh sanctions. No one really knows whether Vladimir Putin will decide to end Russian participation in the International Space Station. Certainly, making it appear to a domestic audience that he was stranding a NASA astronaut in space might make him look "strong" to some Russian people. But there are simply no indications this will happen.

On Thursday the head of Russia's space agency "warned that new sanctions imposed on his country could have dire consequences for the International Space Station program," reports Space.com (in an article shared by Slashdot reader Hmmmmmm): "Do you want to destroy our cooperation on the ISS?" read one of the tweets from Roscosmos Director-General Dimitry Rogozin, which was translated by Rob Mitchell for Ars Technica senior space editor Eric Berger, who shared Mitchell's translation on Twitter. Russia and the United States are the major partners in the ISS program, which also includes Canada, Japan and multiple European nations...

NASA, however, told Space.com later Thursday that civil cooperation between the U.S. and Russia in space will continue, particularly with regard to the ISS.

But Rogozin struck a much different tone, suggesting that the new sanctions could potentially result in the ISS crashing to Earth in an uncontrolled fashion. (The Russian segment of the ISS is responsible for guidance, navigation and control for the entire complex, according to the European Space Agency. And Russian Progress cargo craft provide periodic orbit-raising boosts for the ISS, to ensure that it doesn't sink too low into Earth's atmosphere....) Rogozin also stressed that the ISS would deorbit naturally without periodic reboosts courtesy of Progress freighters....

Just days ago, however, a Cygnus spacecraft built by aerospace company Northrop Grumman arrived at the ISS with a mandate to perform the program's first operational reboost, which may eventually transfer this capability to U.S. vehicles as well.
Business Insider reports that Thursday's tweets from the head of Russia's space agency also included a dire hypothetical. "If you block cooperation with us, who will save the ISS from an uncontrolled deorbit and fall into the United States or Europe?"

On Saturday Elon Musk "responded by posting the logo of his company, SpaceX." Musk appeared to confirm that SpaceX would get involved, should the ISS fall out of orbit. A Twitter user asked if that's what the tech mogul really meant, to which Musk simply replied: "Yes."

NASA, meanwhile, said it "continues working with Roscosmos and our other international partners in Canada, Europe, and Japan to maintain safe and continuous ISS operations," in a statement to Euronews.

Major rightsholders and internet companies in Russia have signed a new memorandum of cooperation designed to make pirated movies, TV shows and other content harder to find. In addition to automatically removing reported infringing links within hours, search engines have agreed to completely deindex all domains that carry 100 or more links to infringing content. TorrentFreak reports: Signed in 2018, a memorandum of cooperation signed by major rightsholders and internet companies including Yandex changed the way infringing content is handled. Following the creation of a centralized database of pirated content, the Internet companies agreed to query it every few minutes in order to remove corresponding content from their platforms within six hours. Over a period of three years, more than 40 million infringing links have now been removed from search results. Since its introduction, the memorandum has been renewed several times alongside calls for the system to be opened up to a wider range of rightsholders, such as those operating in the publishing sector. While that is yet to happen, a new memorandum has just been signed by the original signatories containing an even more powerful anti-piracy tool.

Under the current agreement (which is set to expire early September 2022), rightsholders must submit specific URLs to infringing content to the centralized database controlled by the Media Communications Union (ISS). These specific URLs are then delisted by search engines but rightsholders complain that the same content can reappear under a new URL, meaning that the process must be repeated. To deal with this type of 'pirate' countermeasure, the new memorandum requires search companies to take more stringent action. Any domain that has 100 or more 'pirate' links reported to the database will be deindexed entirely by search engines, meaning that they essentially become invisible to anyone using a search engine. This must be carried out quickly too, within 24 hours according to ISS. Given the number of links to infringing content posted to non-pirate sites, safeguards will also be introduced to protect legitimate resources from deindexing. These include media sites, government projects, search engines themselves, social networks, and official content providers. "Alongside the development of the memorandum a new law is being drafted, with the aim of enshrining its voluntary terms into local law," adds TorrentFreak. "That should allow other rightsholders that aren't current signatories to obtain similar benefits. At the time of writing, however, progress on the legal front is taking its time and might still take a few more months."

The International Space Station (ISS) will continue its operations until 2030 before heading for a watery grave at the most remote point in the Pacific, Nasa confirmed in a new transition plan this week. The Guardian reports: More than 30 years after its 1998 launch, the ISS will be "de-orbited" in January 2031, according to the space agency's budget estimates. Once out of orbit the space station will make a dramatic descent before splash landing in Point Nemo, which is about 2,700km from any land and has become known as the space cemetery, a final resting place for decommissioned space stations, old satellites, and other human space debris. Also known as the "Oceanic Pole of Inaccessibility" or the "South Pacific Ocean Uninhabited Area," the region around the space cemetery is known for its utter lack of human activity. It's "pretty much the farthest place from any human civilization you can find," as NASA put it. Nasa said it plans to continue future space research by buying space and time for astronaut scientists on commercial spacecraft.

The International Space Station's operations have been extended through 2030, NASA announced on Friday. "Though it was never in doubt that the U.S. would continue its near-term commitment to the ISS," reports Engadget, "NASA's announcement comes amid heightened tensions with Russia, one of several nations sharing access to the Space Station. 2021 also saw Russia deepen its cooperation in space with China, another US adversary, as The New York Times noted in June."

NASA's announcement emphasized it would continue work with the space agencies of Europe, Japan, Canada, and Russia "to enable continuation of the groundbreaking research being conducted in this unique orbiting laboratory through the rest of this decade." From NASA.gov: "The International Space Station is a beacon of peaceful international scientific collaboration and for more than 20 years has returned enormous scientific, educational, and technological developments to benefit humanity...." said NASA Administrator Bill Nelson. "As more and more nations are active in space, it's more important than ever that the United States continues to lead the world in growing international alliances and modeling rules and norms for the peaceful and responsible use of space...." Nearly 110 countries and areas have participated in activities aboard the station, including more than 1,500,000 students per year in STEM activities.

Instruments aboard the ISS, used in concert with free-flying instruments in other orbits, help us measure the stresses of drought and the health of forests to enable improved understanding of the interaction of carbon and climate at different time scales. Operating these and other climate-related instruments through the end of the decade will greatly increase our understanding of the climate cycle.

Extending operations through 2030 will continue another productive decade of research advancement and enable a seamless transition of capabilities in low-Earth orbit to one or more commercially owned and operated destinations in the late 2020s. The decision to extend operations and NASA's recent awards to develop commercial space stations together ensure uninterrupted, continuous human presence and capabilities; both are critical facets of NASA's International Space Station transition plan.
NASA's announcement also points out that the Space station has hosted "more than 3,000 research investigations from over 4,200 researchers across the world."

$100 billion was spent building the International Space Station — including 42 different assembly flights, reports Recode. Yet "after two decades in orbit, the International Space Station will shut down," as NASA re-focuses on sending humans back to the moon. (UPDATE: NASA has extended ISS operation through 2030.)

While they plan to keep it functioning as long as possible, NASA "has only technically certified the station's hardware until 2028 and has awarded more than $400 million to fund private replacements." (Which they estimate will save them $1 billion a year.)

So then what happens? When these stations are ready, NASA will guide the ISS into the atmosphere, where it will burn up and disintegrate. At that point, anyone hoping to work in space will have to choose among several different outposts. That means countries won't just be using these new stations to strengthen their own national space programs, but as lucrative business ventures, too. "Commercial companies have the capability now to do this, and so we don't want to compete with that," Robyn Gatens, the director of the ISS, told Recode. "We want to transition lower-Earth orbit over to commercial companies so that the government and NASA can go use resources to do harder things in deep space."

Private companies currently backed by NASA, including Lockheed Martin and Jeff Bezos's Blue Origin, could launch as many as four space stations into Earth's orbit over the next decade. NASA is also building a space station called Gateway near the moon; a SpaceX Falcon Heavy rocket carrying the living quarters for the station is scheduled to launch in 2024.

Russia and India are planning to launch their own space stations to low-Earth orbit, too, and China's Tiangong station, which is currently under construction, already has astronauts living aboard... Russia may leave the ISS as soon as 2025, the same year its space agency, Roscosmos, plans to launch its new $5 billion space station. The European Space Agency, which represents 22 different European countries, is now training its astronauts for eventual missions to Tiangong...

[C]ompetition for customers could get even more intense as space stations launched by China, Russia, and India open for business.
Recode ultimately sees a future where private-sector customers choose from competing space stations — and even have to consider the political consequences of "favoring one nation's space station over another..."

"In the best of scenarios, these new stations will learn from each other and massively expand scientific knowledge. But they will also make global politics a much bigger part of space, which could impact what happens here on Earth and how humanity explores the moon and Mars."

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 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.
