Astrophotographer Spots Spacewalking Astronauts From the Ground (space.com) 35

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 Ending Production of Flagship Crew Capsule (reuters.com) 38

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 Faces Unclear Future (reuters.com) 22

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."

Russia's Cosmonauts Arrive on the Space Station - Wearing Ukraine's Colors (space.com) 137

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.

Ex-NASA Astronaut Scott Kelly Says He's Ending Feud With Russian Space Chief (wsj.com) 37

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."

US Astronaut's Return Hangs in the Balance as Tensions With Russia Escalate (theguardian.com) 70

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.

No, Russia Has Not Threatened To Leave An American Astronaut Behind In Space (arstechnica.com) 73

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.

NASA Assures ISS Will Continue Orbiting Despite Sanctions on Russia (msn.com) 78

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.

Search Engines In Russia Will Deindex All Domains That Have 100+ Links To Pirated Content (torrentfreak.com) 49

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."

ISS Will Plummet To a Watery Grave In 2030 (theguardian.com) 87

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.

US Extends Space Station Operations Through 2030 (nasa.gov) 17

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."

What's Next After the International Space Station? (vox.com) 98

$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."

NASA's New Sleeping Bags Could Prevent Eyeball 'Squashing' On the ISS (engadget.com) 41

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.

International Space Station Fired Its Thrusters Friday To Dodge More Space Debris (space.com) 13

"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.

NASA Awards Blue Origin, Nanoracks, Northrop Grumman Over $400M In Contracts To Avoid Space Station Gap (techcrunch.com) 39

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.

US Satellites Are Being Attacked Every Day According To Space Force General (thedrive.com) 171

An anonymous reader quotes a report from The Drive: U.S. Space Force's General David Thompson, the service's second in command, said last week that Russia and China are launching "reversible attacks," such as electronic warfare jamming, temporarily blinding optics with lasers, and cyber attacks, on U.S. satellites "every single day." He also disclosed that a small Russian satellite used to conduct an on-orbit anti-satellite weapon test back in 2019 had first gotten so close to an American one that there were concerns an actual attack was imminent.

Thompson, who is Vice Chief of Space Operations, disclosed these details to The Washington Post's Josh Rogin in an interview on the sidelines of the Halifax International Security Forum, which ran from Nov. 19 to 21 in Halifax, Nova Scotia, in Canada. The forum opened just four days after a Russian anti-satellite weapon test involving a ground-launched interceptor, which destroyed a defunct Soviet-era electronic intelligence satellite and created a cloud of debris that presents a risk to the International Space Station (ISS). That test drew widespread condemnation, including from the U.S. government, and prompted renewed discussion about potential future conflicts in space.

"The threats are really growing and expanding every single day. And it's really an evolution of activity that's been happening for a long time," Thompson, told Rogin. "We're really at a point now where there's a whole host of ways that our space systems can be threatened." "Right now, Space Force is dealing with what Thompson calls 'reversible attacks' on U.S. government satellites (meaning attacks that don't permanently damage the satellites) 'every single day,'" according to Rogin. "Both China and Russia are regularly attacking U.S. satellites with non-kinetic means, including lasers, radio frequency jammers, and cyber attacks, he said." [...] Thompson's assertion that these kinds of attacks are occurring with extreme frequency is new. It underscores the rapid development and fielding by Russia and China, among others, of a wide variety of anti-satellite capabilities, something the U.S. military has called increasing attention to in recent years. "The Chinese are actually well ahead [of Russia]," Thompson told Rogin. "They're fielding operational systems at an incredible rate."
"Thompson could not confirm or deny whether any American satellites had actually been damaged in a Russian or Chinese attack," the report adds. "[H]e told Rogin that even if such a thing had occurred, that very fact would be classified."

He did, however, provide new details about the incident in 2019 where a small Russian satellite released a projectile in one on-orbit anti-satellite weapon test. According to The Drive, "Russia's satellite had first got in very close to a U.S. 'national security satellite' and that 'the U.S. government didn't know whether it was attacking or not.'"

"It maneuvered close, it maneuvered dangerously, it maneuvered threateningly so that they were coming close enough that there was a concern of collision," Thompson said. "So clearly, the Russians were sending us a message."

NASA Postpones Spacewalk Citing 'Debris Notification' for ISS (theguardian.com) 13

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."

Russia May Have Just Shot Down Its Own Satellite, Creating a Huge Debris Cloud (arstechnica.com) 176

An anonymous reader quotes a report from Ars Technica: The seven astronauts and cosmonauts onboard the International Space Station sheltered inside their respective spacecraft, a Crew Dragon and Soyuz, on Monday morning as the orbiting laboratory passed through an unexpected debris field. This was not a pre-planned collision avoidance maneuver in low Earth orbit, in which the station would use onboard propulsion to move away. Rather, the situation required the astronauts to quickly take shelter. Had there been a collision during the conjunction, the two spacecraft would have been able to detach from the space station and make an emergency return to Earth. Ultimately that was not necessary, and the astronauts reemerged into the space station later Monday. However, as the crew on board the station prepared for their sleep schedule, Mission Control in Houston asked them to keep as many of the hatches onboard the space station closed for the time being, in case of an unexpected collision during subsequent orbits.

It appears likely that the debris field that had alarmed flight controllers on Monday was caused by an anti-satellite test performed by Russia's military early on Monday. [...] It appears that Russia launched a surface-to-space Nudol missile on Monday, between 02:00 and 05:00 UTC, from the Plesetsk Cosmodrome in the northern part of the country. The missile then struck an older satellite, Cosmos 1408. Launched in 1982, the satellite had been slowly losing altitude and was a little more than 450 km above the Earth. This is a large satellite, with a mass of about 2,000 kg. As of Monday afternoon, US Space Command said it was already tracking more than 1,000 pieces of new debris. Although the satellite's altitude is higher than the International Space Station, which is about 400 km above the surface, a kinetic impact would spread a large cloud of debris. Satellite expert Jonathan McDowell believes the Cosmos 1408 satellite is the likely candidate for the space station's ongoing debris event.

During a daily briefing today, US State Department Spokesman Ned Price said the test had created more than 1,500 pieces of trackable debris and hundreds of thousands of pieces of un-trackable debris. "The Russian Federation recklessly conducted a destructive satellite test of a direct-ascent anti-satellite missile against one of its own satellites," Price said. "This test will significantly increase the risk to astronauts and cosmonauts on the International Space Station as well as to other human spaceflight activities. Russia's dangerous and irresponsible behavior jeopardizes the long-term sustainability of outer space."

SpaceX's Dragon Spacecraft Successfully Docks At ISS With Four Astronauts Onboard (foxbusiness.com) 39

SpaceX's Crew Dragon spacecraft successfully docked with the International Space Station on Thursday evening, less than 24 hours after it launched from NASA's Kennedy Space Center. Fox Business reports: NASA astronauts Raja Chari, Tom Marshburn, and Kayla Barron, as well as European Space Agency astronaut Matthias Maurer, will spend six months at the ISS conducting scientific research and monitoring the space station. The launch was supposed to occur nearly two weeks ago, but was delayed by bad weather and an undisclosed medical problem with a crew member. Wednesday's launch carried the 600th person to ever reach orbit and comes just days after SpaceX returned four astronauts to Earth on Monday, bringing an end to a 200-day mission at the space station.

Jeff Bezos' Blue Origin Wants To Build a Tourism Space Station Nearly As Big As the ISS 88

Blue Origin, the rocket and space tourism company founded by Jeff Bezos, is proposing a massive new commercial space station called "Orbital Reef" that could be used to host science experiments, vacation getaways, and potentially even in-space manufacturing. CNN reports: The company plans to work alongside startup Sierra Space to bring the space station to fruition, and Boeing plans to design a research module on the station, though there are no guarantees the companies can make it happen. Such projects are still exorbitantly expensive and risky, likely costing in the tens of billions of dollars and requiring multiple safe launches before a human ever even floats aboard. Blue Origin and Sierra Space plan to co-finance the space station, though executives declined to give an all-in cost estimate during a press conference Monday. They did add that they are expecting to sign on NASA as an anchor tenant, though it's not exactly clear how such a partnership could take shape.

Blue Origin hopes Orbital Reef could be operational in the late 2020s, though it will have to get quite a bit done to make that happen. The company has only managed a few crewed suborbital flights so far, much like NASA first achieved back in the early 1960s, and it has yet to put a spacecraft in orbit, let alone a person. A space station would take a major leap. New Glenn, the Blue Origin-built rocket that is expected to be powerful and large enough to haul the biggest portions of the space station to orbit, is not yet operational, and its maiden flight was recently delayed to at least late 2022. The orbital reef will be able to host up to 10 people and will have roughly the same internal volume as the ISS.
