Northrop Grumman launches Cygnus freighter to ISS

8:29 am

Capitalism in space: Northrop Grummann yesterday used its Antares rocket to successfully launch its Cygnus freighter to ISS.

This fact about this Cygnus is important:

This is the first Cygnus mission featuring enhanced capabilities to perform a re-boost to the space station’s orbit as a standard service for NASA; one re-boost is planned while Cygnus is connected to the orbiting laboratory.

In other words, Cygnus has been enabled to replace the boost capability that the Russians and Japanese provided.

The 2022 launch race:

6 SpaceX
2 China
2 Russia
1 Virgin Orbit
1 ULA
1 India
1 Europe (Arianespace)
1 Northrop Grumman

NASA outlines plans for ISS deorbit and the transition to commercial stations

9:55 am

Capitalism in space: NASA on January 31st released its updated plan for transitioning all government manned orbital operations to commercial private space stations in the next eight years in preparation for the deorbiting of ISS in early 2031.

You can read the report here [pdf]. The key paragraph however is this:

NASA has … signed agreements with three U.S. companies (Blue Origin of Kent, Washington; Nanoracks LLC of Houston, Texas; and Northrop Grumman Systems Corporation of Dulles, Virginia) to develop commercial destinations in space that go directly to orbit, i.e., free-flyers. The awards, along with the Axiom concept [where the private station starts as part of ISS and then later separates], are the first part of a two-phase approach to ensure a seamless transition of activity from the ISS to commercial destinations. During this first phase, private industry, in coordination with NASA, will formulate and design [commercial space stations] capabilities suitable for potential Government and private sector needs. The first phase is expected to continue through 2025.

For the second phase of NASA’s approach to a transition toward [commercial space stations], the Agency intends to certify for NASA crew member use [commercial space stations] from these and potential other entrants, and ultimately, purchase services from destination providers for crew to use when available.

It is NASA’s goal to be one of many customers of commercial LEO destination services, purchasing only the goods and services the Agency needs. [Commercial space stations], along with commercial crew and cargo transportation, will provide the backbone of the human LEO ecosystem after the ISS retires. [emphasis mine]

The report predicts that, by using private stations instead of building its own, the agency will save up to two billion dollars per year, money it can than use of planetary missions. This of course is assuming NASA cancels SLS. If not, I predict that overpriced cumbersome rocket will quickly absorb all this money saved.

The highlighted sentence indicates that NASA continues to accept entirely the recommendations I made in my 2017 policy paper, Capitalism in Space [a free pdf download]. In fact, that sentence is almost an exact quote from one of most important recommendations.

ISS government partners give okay to Axiom’s first commercial crew to station

9:26 am

Capitalism in space: NASA announced yesterday that it as well as the other international partners for ISS have approved the crew and passengers who will fly on Axiom’s first commercial flight to the station, presently scheduled for launch on March 30, 2022, flying in SpaceX’s Endeavour capsule.

Axiom Space astronauts Michael López-Alegría, Larry Connor, Mark Pathy, and Eytan Stibbe are prime crew members of the Ax-1 mission. López-Alegría, who was born in Spain, raised in California, and a former NASA astronaut, will serve as the mission commander. Connor, of Dayton, Ohio, will serve as pilot. Pathy, from Canada, and Stibbe, from Israel, will be mission specialists. The quartet is scheduled to spend eight days aboard the orbiting laboratory conducting science, education, and commercial activities before their return to Earth.

Because the four will be staying at this government station, they must work with NASA, which appears to be requiring them to do some research while on board. Those experiments are still “under review” though Axiom has already revealed a suite of microgravity experiments the crew will perform.

Axiom & UK entertainment company propose film studio in space

10:03 am

Film studio balloon

Capitalism in space: Axiom has signed a deal with British-based entertainment company, Space Entertainment Enterprise (SEE) to add an inflatable film studio module to its private commercial space station.

Axiom Space’s modules are to be added to the ISS throughout the second half of the 2020s. SEE-1 would be added along with these components.

Once the ISS program is near its end, the plan is for the commercial segment to be detached to form an independent station.

According to SEE, the spherical studio module is planned to be about 20 feet (6 meters) in diameter once fully expanded in space. Its interior is expected to provide an “unobstructed pressurized volume” that can be adapted for a range of media activities, including film production, music, sports and livestreaming events.

The graphics that accompanied the press release of the British company make me very skeptical of it. Posted on the right, it shows this inflatable module as a simple sphere, like a balloon. No manned module ever built, including the inflatable modules launched by Bigelow, has ever looked anything like this. This suggests a certain level of ignorance from the entertainment company which also suggests this project really doesn’t yet exist. The press release and agreement with Axiom seems instead merely an effort to drum up investment capital from investors who know even less.

Flight dates for SpaceX’s next two manned flights to ISS revised

9:24 am

Capitalism in space: A NASA official yesterday announced that the flight dates for SpaceX’s next two manned flights have been firmed up, with the private commercial Axiom AX-1 flight delayed from February 21st to March 31st, followed two weeks later by NASA’s own manned mission on April 15th.

Axiom has also noted that this commercial flight, piloted by a former NASA astronaut and carrying three passengers, will be its only commercial manned flight in ’22.

…Commanded by former NASA astronaut Michael López-Alegría, Ax-1 will only carry private citizens. Each paying $55 million for the privilege, the mission’s three customers are Larry Connor, Mark Pathy, and Eytan Stibbe – all businessmen who’ve respectively amassed multmillion-dollar fortunes in real estate; entertainment and shipping; and military equipment and venture capitalism.

Their Dragon spacecraft will be Resilience, making its third flight.

Axiom’s next private commercial flight has now been delayed until ’23.

NASA: Russian anti-satellite test in November doubled the threat to ISS

9:17 am

According to a presentation by a NASA official at a conference today, further tracking of the debris from the Russian anti-satellite test on November 15, 2021 suggests that it has doubled the overall chance of a debris collision with ISS.

NASA ISS Program Director Robyn Gatens told a NASA advisory committee today that the November 15, 2021 Russian ASAT test forced the Expedition 66 crew to implement safe haven procedures, closing hatches to parts of the ISS and sheltering in the Soyuz and Crew Dragon spacecraft that could return them to Earth if worse came to worse.

Russia denied the test imperiled the crew, but Gatens said the threat of a piece of debris penetrating the ISS now has doubled to one chance in 25,000-33,000 orbits, versus one in 50,000 orbits prior to the test. The ISS does about 6,000 orbits a year.

It should be noted that, according to these numbers, the overall threat seems quite manageable. Nonetheless, the Russian anti-sat test was entirely irresponsible, especially because it targeted a defunct satellite in an orbit slightly higher than ISS, which means its debris will over time move into ISS’s orbit. The test also violated the Outer Space Treaty, which Russia has signed, which requires all signatories to control what they do in space so that it does not threaten either the persons or property of anyone else.

Russian astronauts locate another leak on Zvezda

8:44 am

According to Russia’s state-run TASS press, Russian astronauts have located what it calls “the last air leak” on the Zvezda module of ISS.

Russian cosmonauts Anton Shkaplerov and Pyotr Dubrov discovered the last air leak location in the International Space Station’s Zvezda module, Roscosmos spokesman Dmitry Strugovets said Tuesday, adding that the leak will be eliminated after special equipment is delivered to the station.

Like most of the other leaks previously found, this one was located in the aft transition chamber where the Zvezda docking port is located, once again suggesting that these leaks are the result of stress fractures caused by age and the more than a hundred dockings that have occurred there since Zvezda was launched more than twenty years ago.

The Russians’ belief that no more leaks will be found is probably based on their decision to reduce, even cease the use of this port. The new Prichal docking hub, which two Russians today are doing a spacewalk to finalize its integration with the station, makes the shuttering of Zvezda’s port possible.

At the same time, the existence of numerous stress fractures in an ISS module is not something to be dismissed lightly, as the TASS article attempts to do. It is akin to cracks in the hull of a submarine, and I don’t know anyone who would be willing to send such a vessel deep underwater.

Russian researchers: ISS home to more than 20 types of microorganisms

8:59 am

After studying more than 200 samples from ISS brought back to Russia, researchers have identified more than 20 types of microorganisms that make their home on ISS, including some pathogens and fungi.

The habitat of the module and the entire Russian segment of the ISS is an environmental niche home to bacteria and microscopic fungi, the materials suggest. “These microorganisms use the station’s decorative-finishing and design materials as their basic habitat,” according to the materials.

The experiment aboard the ISS involved taking samples and delivering them to Earth in descent modules. In the course of three years, over 200 samples were taken, with bacteria discovered in 34% and fungi in 3% of them. “In 5% of the samples with the presence of bacterial microflora and in 100% of the samples with the presence of fungal microflora, the standard indicator regulated by SSP 50260 NORD was exceeded,” the materials say.

The fungi indicate mold, a long known problem on manned space stations first identified by the Russians on their Salyut stations in the ’70s and ’80s. The pathogens do not appear to be harmful, or else the astronauts would have experienced sicknesses. No such sicknesses have been reported, though they might have occurred but have not been released publicly due to medical privacy concerns.

Study: Weightlessness might produce long term anemia

3:13 pm

The uncertainty of science: A study of fourteen astronauts who spent six months on ISS has found that weightlessness appears to increase the loss of red blood cells, and that the continuing loss extends well past their return to Earth.

Before this study, space anemia was thought to be a quick adaptation to fluids shifting into the astronaut’s upper body when they first arrived in space. Astronauts lose 10 percent of the liquid in their blood vessels this way. It was thought astronauts rapidly destroyed 10 percent of their red blood cells to restore the balance, and that red blood cell control was back to normal after 10 days in space.

Instead, Dr. Trudel’s team found that the red blood cell destruction was a primary effect of being in space, not just caused by fluid shifts. They demonstrated this by directly measuring red blood cell destruction in 14 astronauts during their six-month space missions.

On Earth, our bodies create and destroy 2 million red blood cells every second. The researchers found that astronauts were destroying 54 percent more red blood cells during the six months they were in space, or 3 million every second. These results were the same for both female and male astronauts.

The study also found that for as much as a year afterward the astronauts continued to lose red blood cells at a rate 30% greater than normal.

The researchers immediately suggested further invasive monitoring of anyone who wants to go to space. From their paper:

Space tourism will considerably expand the number of space travelers. Medical screening of future astronauts and space tourists might benefit from a preflight profiling of globin gene and modifiers. Postlanding monitoring should cover conditions affected by anemia and hemolysis. Monitoring individual astronaut’s levels of hemolysis during mission may be indicated to reduce health risks.

Without question, this data strongly suggests that it would be wise for anyone who wants to go into space for long periods have themselves checked for anemia, and have it treated prior to going, or if they still have it at launch time to decide not to go. However, the choice should belong to the individual, not bureaucrats imposing regulations or legislators passing laws.

Unfortunately, our modern leftist society now assumes such decisions no longer belong to the individual, but must be made by their betters in Washington. Provisions in the 2004 Space Amendments act allows the FAA to impose such invasive medical testing on future space tourists. Its bureaucrats have not yet done so, but the recent history with government mandates over the COVID shots suggests strongly that they will not hesitate to do so when they think they can get away with it.

Biden administration commits to operating ISS through 2030

5:46 pm

The Biden administration yesterday announced that it has committed NASA to operating the International Space Station (ISS) through 2030, a six year extension to the previous end date of 2024.

Today’s abrupt announcement on a federal holiday comes one day after Biden and Putin had a “serious and substantive” telephone conversation about the situation in Ukraine where Russian troops are massed at the border. Biden has said that if Russia invades Ukraine the United States and its allies will respond with more economic sanctions. A Russian official told reporters later that Putin warned Biden that any such sanctions “could result in a ‘complete rupture’ of relations” between the two countries, according to the New York Times.

…Asked why the ISS extension was announced today and if it is related to the Biden-Putin call, a NASA spokesperson told SpacePolicyOnline.com only that it has “been in the works for months.”

A White House commitment to 2030 falls short of setting the date in law, but demonstrates U.S. intentions at least as long as Biden is President. Whether the other partners, especially Russia, agree will be interesting to watch. ESA’s Director General, Josef Aschbacher, welcomed the news, but it will be the 11 ESA members who participate in the program who make the decision.

The article gives a good overview of the political issues, and notes accurately that it will be very difficult to operate the station if Russia and the U.S. part ways and Russia leaves the partnership.

What the article did not mention is the fragile state of some of Russia’s modules. Both Roscosmos and NASA know that the Zvezda module, the second oldest on ISS, is showing very worrisome signs of aging, including many stress fractures that have caused small airleaks. The Russians themselves have admitted that the module is failing, and have added that because of this fact the Putin government has begun work on a new and independent Russian station.

It is unclear if ISS could function if Zvezda became unusable. At a minimum its capabilities will be reduced. At worst it might not be safe to occupy.

The Biden administration and NASA can extend ISS on paper as much as they want, but reality suggests that it will be a dangerous challenge to keep the station running until 2030. The real solution is to get as many private commercial American stations launched in the next few years, so that when Zvezda fails, there will be viable options to ISS.

SpaceX launches cargo Dragon to ISS using new 1st stage

9:39 am

Capitalism in space: In what will likely be its last launch in 2021, SpaceX early this morning successfully launched a reused Dragon cargo capsule to ISS.

This was the company’s 31st launch in 2021, extending its record for the most launches in a single year by a private company. The launch’s big news however was that the company used a new first stage booster, only the second time in 2021 that it needed to do so (the first was in May). The first stage successfully landed on the drone ship in the Atlantic, completing SpaceX’s 100th successful recovery.

The first such vertical landing had occurred in December 2015, and now six years later and after a hundred vertical landings, SpaceX remains the only orbital rocket entity in the world with such a capability. A very small handful of companies have performed tests with smaller scale prototypes, but that so much time has passed and no one has pushed forward to meet SpaceX’s challenge with even some full scale preliminary test flights does not reflect well on the innovative culture of the world’s rocket industry.

As for SpaceX’s yearly record, 31 launches actually exceeds the number of launches the entire U.S. rocket industry generally managed each year from 1970 through 2017. During much of that time the launch industry was run by NASA in a Soviet-style top-down system that stifled competition and innovation. Beginning in 2008, when SpaceX won its first contract with NASA, that system was abandoned by NASA, switching instead to capitalism and competition, whereby NASA was merely a customer buying its launches from the open market. The positive results from that change have been breath-taking, proving once again that freedom, competition, and private enterprise will win every single time over government programs and communist/socialist ideology.

The leaders in the 2021 launch race:

48 China
31 SpaceX
22 Russia
6 Europe (Arianespace)
5 ULA
5 Rocket Lab

The U.S. and China are now tied 48 to 48 in the national rankings. This was the 127th launch in 2021, tying it with 1976 for the second most successful year in rocketry in the history of space exploration. With five more announced launches on the schedule, there is a chance that this year could tie the record year, 132 in 1975.

Japanese tourists return to Earth after 12 days in space

8:35 am

Capitalism in space: Japanese tourists billionaire Yusaku Maezawa and his assistant Yozo Hirano safely returned to Earth yesterday in their Russian Soyuz capsule after spending 12 days on the Russian half of ISS.

Maezawa’s and Hirano’s flight contracts were negotiated by Space Adventures, the only company to date to fly its clients to the International Space Station. Prior to Soyuz MS-20, Space Adventures organized eight flights for seven self-funded astronauts (one flew twice).

Maezawa, 46, is the CEO of Start Today and founder of ZOZO, an online retail clothing business, which he sold to Yahoo! Japan. In 2018, he paid an undisclosed but substantial amount to SpaceX for a circumlunar flight on the company’s still-in-development Starship spacecraft. Maezawa’s “dearMoon” mission, which will fly him and a crew of artists around the moon, is currently targeted for launch in 2023.

Hirano, 36, managed the photography team at ZOZO and is now a film producer at Start Today. In addition to filming Maezawa during the mission, Hirano also took part in human health and performance research on behalf of the Translational Research Institute for Space Health (TRISH) at the Baylor College of Medicine in Houston, Texas. The studies included collecting electrocardiogram readings and using a portable auto-refractor device to collect sight data.

The article also notes a minor record set during this tourist flight. On December 11th a total of 19 people were in space, the most ever, though only for a very short time. Ten were on ISS, three were on China’s space station, and then six were launched on a suborbital flight that day by Blue Origin.

The next commercial tourist flight on the schedule is February’s first Axiom flight to ISS, carrying three customers to ISS for eight days.

Russia selects first astronaut to fly on Dragon

8:19 am

Russia, as part of the continuing barter deal with NASA for seats on the capsules of both countries, has selected rookie astronaut Anna Kikina to be the first Russian to fly on a Dragon capsule.

Kikina is the only woman currently active in the Russian cosmonaut corps. She was selected in 2012 but has yet to fly in space, although Rogozin and other Russian officials had previously said she would fly in the fall of 2022. She would likely be on the Crew-5 Crew Dragon mission, to which NASA astronauts Nicole Mann and Josh Cassada and JAXA astronaut Koichi Wakata are currently assigned.

While according to the Russians the barter deal is finalized, according to NASA negotiations are still ongoing. This announcement by the Russians might actually be a negotiating tactic, since the tensions between the U.S. and Russia over Russian threats to the Ukraine could threaten the partnership at ISS. By making this announcement the Russians might be trying to make the barter deal an accomplished fact.

Russia launches two tourists to ISS

8:25 am

Capitalism in space: Using its Soyuz-2 rocket and Soyuz capsule, Russia today successfully launched two tourists to ISS.

Onboard the Soyuz is Yusaku Maezawa, a Japanese billionaire known for starting online businesses Start Today and Zozo. In addition to his Soyuz mission, he has a circumlunar flight aboard SpaceX’s Starship—called “dearMoon”—booked for no earlier than 2023. Maezawa purchased both available seats on this flight of Soyuz. He [is] joined by Yozo Hirano—a media producer from Zozo—who will document the MS-20 mission. This flight will mark the first time two Japanese astronauts fly together, as well as the first flight of any Japanese space tourist.

The mission is commanded by experienced Russian cosmonaut Alexander Misurkin, on what is his third spaceflight. During the mission, he will stand ready to pilot the Soyuz in case the automated guidance software fails.

The Russians claim that this is their first tourist flight to ISS since 2009, but that makes believe the two filmmakers launched to ISS in October were not paying passengers. They might have been working on ISS, and not merely tourists, but they were not professional astronauts but paying customers.

This flight however is the first organized with Russia by the American company Space Adventures since 2009, ending that long gap caused almost entirely because all Soyuz seats since then had been bought by NASA to replace the shuttle. With manned Dragon flights available, the Russians and Space Adventures can sell tickets again.

The leaders in the 2021 launch race:

46 China
27 SpaceX
21 Russia
6 Europe (Arianespace)
5 ULA

China still leads the U.S. 46 to 43 in the national rankings. With SpaceX and Rocket Lab launches set for later tonight, these numbers should rise again.

NASA buys more Dragon manned flights

9:41 am

Capitalism in space: To give it some coverage because of continuing delays in Boeing’s Starliner manned capsule, NASA announced yesterday that it has awarded SpaceX contracts for three more manned Dragon manned flights to ISS.

NASA issued a contract notification announcing its plans to issue a sole-source award to SpaceX for three missions. Those missions would be in addition to the six “post-certification missions,” or PCMs, that SpaceX won as part of its $2.6 billion Commercial Crew Transportation Capability (CCtCap) contract in 2014. The announcement did not state the price of those three new missions.

This is money that would have gone to Boeing, if it had gotten its act together and gotten Starliner flying on schedule. Instead, SpaceX is making the profits.

There has been no updates from Boeing since October on the valve issue that now stalls Starliner. While Boeing claims it is aiming for an unmanned demo flight to ISS in early ’22, this remains entirely speculative at this moment.

Astronauts successfully complete spacewalk, replace broken antenna

12:37 pm

After a two day delay caused by the danger of impact from debris from the Russian anti-sat test, two astronauts today successfully completed a six-hour-plus spacewalk to replace a malfunctioning antenna on ISS.

NASA astronauts Thomas Marshburn and Kayla Barron concluded the first Expedition 66 spacewalk at 12:47 p.m. EST, after 6 hours and 32 minutes. Marshburn and Barron successfully installed an S-band Antenna Subassembly (SASA) on the Port-1 truss structure and stowed the failed antenna. Additionally, the pair completed get-ahead tasks on the Port-4 truss structure, including resetting the torque on a set of bolts.

This was the fifth spacewalk for Marshburn, the first for Barron, and the 13th spacewalk at the International Space Station this year. Marshburn has now spent a total of 31 hours and one minute spacewalking, and Barron’s spacewalking time is now 6 hours and 32 minutes. Space station crew members have now spent a total of 64 days, 12 hours, and 26 minutes working outside the station conducting 245 spacewalks in support of assembly and maintenance of the orbiting laboratory.

It is unclear if any debris that canceled the spacewalk earlier in the week ever came close to the station. It is just as likely that NASA was overly cautious.

NASA postpones ISS spacewalk due to debris from Russian anti-sat test

9:41 am

NASA today postponed a planned ISS spacewalk to fix an antenna because of a threat from debris from the Russian anti-sat test.

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.

This problem is only going to get worse. The Russians did something with that anti-satellite test that was either so stupid as to defy logic, or intentional in the worst sort of way. Russia’s actions actually suggest the Putin administration wanted to sabotage ISS.

Russians set December 8th for launch of next ISS tourist flight

10:17 am

Capitalism in space: Roscosmos today announced that the next tourist flight to ISS of two Japanese tourists will launch on December 8th.

“According to the Russian plan of ISS flight, the Soyuz-2.1A rocket carrying the Soyuz MS-20 transport spaceship with the 20th visiting ISS expedition on board is scheduled to lift off from the Baikonur cosmodrome at 10:38 am Moscow time [07:38 GMT] on December 8, 2021,” the agency said.

The crew will include Roscosmos cosmonaut Alexander Misurkin and two Japanese space tourists – billionaire Yusaku Maezawa and his assistant Yozo Hirano

Maezawa is also the man who has signed a deal with SpaceX to fly to the Moon on Starship, once that spacecraft is finished.

Axiom sets launch date for first private commercial manned mission to ISS

8:17 am

Capitalism in space: Axiom has set February 21, 2022 as the target launch date for its first private commercial manned mission to ISS, carrying one employee and three passengers for eight days.

In making the announcement the company emphasized the science research the passengers — Larry Connor, Mark Pathy, and Eytan Stibbe — will do:

The crew activities of Axiom Mission 1 (Ax-1) will focus on science, education, and outreach, conducting approximately 25 experiments while onboard the ISS. Critical data from studies in human research, life and physical sciences, technology demonstrations, and Earth observation will expand the applicability of microgravity research to new sectors. The crew has submitted over 100 hours of human-tended research to conduct during their stay on station.

The commander will be former NASA astronaut Michael López-Alegría, who now works for Axiom. This will be his fifth spaceflight.

Europe joins U.S. in condemning Russian anti-satellite test

8:57 am

Europe’s top space policy chief today joined the U.S. in strongly condemning the Russian anti-satellite test that produced a cloud of several thousand pieces of orbiting space junk.

European Commissioner for Internal Market Thierry Breton condemned Russia’s anti-satellite missile system test, which led to the destruction of a satellite in low orbit.

“As European Union (EU) Commissioner in charge of EU Space policy and in particular of Galileo & Copernicus, I join the strongest condemnations expressed against the test conducted by Russia on Monday November 15, which led to the destruction of a satellite in low orbit (COSMOS 1408),” Breton wrote on Twitter late on Tuesday.

The Russians continue to insist the debris poses no threat to ISS, but their own state-run press proves them wrong. This TASS report claims the debris is no threat because it orbits 40 to 60 kilometers (25 to 35 miles) above the station.

That the debris is presently orbiting above the station is exactly why it poses a threat. While mission controllers will periodically raise ISS’s orbit to counteract the loss of altitude due to friction from the very thin atmosphere at that elevation, the various orbits of the satellite debris will continue to fall. Eventually that entire cloud will be drop into ISS’s orbit.

It is likely that the debris spread over time will make it easy for controllers to shift ISS to avoid individual pieces, but the need to dodge will certainly increase with time, raising the odds that something will hit the ISS.

The test seems almost so stupid an act by Russia that one wonders if its purpose was to create a long term threat to ISS itself. At least one private U.S. company, Axiom, plans to attach its own modules to ISS and use it as a base for the next few years for commercial operations. Others want to use ISS as a hotel for private tourists.

The Russians meanwhile are planning to launch their own new station. If the Russians put it in an orbit safe from this debris cloud, this test will have thus conveniently damaged their main competitor in commercial space operations.

Russian anti-sat test creates 1500 more pieces of space junk

3:40 pm

In what appears to be a test of Russia’s anti-satellite system dubbed Nudol, a defunct Russia satellite has been blasted into approximately 1,500 pieces by a missile launched from Russia.

Under normal circumstances, Kosmos 1408 would not have approached the International Space Station closely enough to pose a threat, however following the breakup, thousands of individual pieces of debris will have scattered into their own orbits. At least 1,500 pieces of debris from the satellite have already been identified by the United States Space Command. However, many smaller objects will have been generated, which will take much longer to identify. With high relative velocities, even a tiny fragment can cause significant damage should it collide with another spacecraft.

Owing to concerns about the debris cloud, the crew aboard the ISS were instructed to close hatches between the space station’s modules and take shelter aboard the Dragon and Soyuz capsules docked to the station.

According to the story at the link, ISS will cut through the expected debris cloud every orbit.

It is amazing that Russia would perform such a test on a satellite with an orbit that close to ISS’s, especially since there are many pieces of abandoned space junk in lower orbits so that their debris clouds would pose little problem, especially because their orbits would decay quickly.

This test is comparable to the Chinese anti-sat test in 2007, which caused a larger debris cloud that still poses a threat to ISS and other working satellites.

According to the Outer Space Treaty, a nation must control the objects it puts in space so that they pose no risk to others. Both the Russian and Chinese anti-sat tests prove these nations have no respect for the treaties they sign.

Russian astronaut id’s possible leak location in Zvezda

9:50 am

A Russian astronaut today told mission control that he thinks he has located another leak in the Zvezda module of ISS.

Roscosmos cosmonaut Pyotr Dubrov detected a possible air leak spot in the intermediate chamber of the Zvezda module aboard the International Space Station (ISS), the cosmonaut told the Flight Control Center during a communications session on Monday.

The Russian cosmonaut said he had traced the possible spot of the continued air leak while inspecting the Zvezda module’s intermediate chamber at the weekend. “I began preparing a perimeter for laying a cord today. I detected a suspicious spot and started to examine it,” the cosmonaut said, replying to a question about the work in the intermediate compartment in a live broadcast by NASA.

As the Russian cosmonaut said, he made a photo of the detected spot using a microscope with magnifying lens. He did not make video footage of the works, he said. [emphasis mine]

The highlighted words are significant. Up until now all leaks that the Russians have identified have been in Zvezda’s aft section, the part where the docking port is located. That pattern suggested that the many dockings over the module’s two decade-plus lifespan could have led to stress fractures in that module.

That they might have now found an air leak in intermediate section of the module suggests that the age-caused stress fractures are occurring in a more widespread manner. This is very concerning.

On a positive note, when the astronauts sealed the earlier leaks in the aft module, the loss of air dropped significantly. If the leak stops entirely when they seal this leak, we will have some confidence that the problem is under some control, for the time being.

ISS to maneuver around space junk leftover from Chinese anti-satellite test

8:41 am

Russian engineers will today fire engines on a Progress freighter docked to ISS to guarantee that a piece of debris left over from a 2007 Chinese military anti-satellite test does not hit the station.

The object the space station will dodge is called 35114 in NASA’s catalog of space objects, and is also identified at 1999-025DKS, a piece of debris from a Chinese anti-satellite weapons test in 2007. Originally part of a Chinese weather satellite, the debris resulted from an in-orbit missile test performed by China. As part of that test, a kinetic-energy, suborbital missile was fired at a defunct Chinese weather satellite called Fengyun-1C (which stopped working in 2002), obliterating it into thousands of pieces.

The destroyed satellite was originally in a much higher orbit, but atmospheric drag has pulled the debris closer to Earth over the years and ultimately into the flight path of the space station. The two objects’ closest approach is estimated to occur on Nov. 12, according to Jonathan McDowell, an astronomer at Harvard who tracks and catalogs objects in space. McDowell tweeted on Tuesday that his calculations show that this will be the 29th space station debris avoidance maneuver, and the third related to the 2007 Chinese anti-satellite test.

The maneuver will take place prior to the arrival of Endurance, carrying four astronauts.

While the anti-sat test initially produced about 3,500 pieces of debris, that number has dropped in the past fourteen years to about 2,700 pieces as the orbits of these objects slowly decay. The test was also another example of China’s willingness to break the Outer Space Treaty. As a signatory China is required to control every object it puts into orbit in order to prevent collisions. Instead, it performed a military test that created debris in the thousands, in orbits that threaten ISS.

We shall get another demonstration of China’s contempt for treaties in the next few months, when it launches two more large modules to its space station and the large core stage of the rocket comes crashing down somewhere on Earth, out of control.

SpaceX successfully launches four astronauts to ISS

7:16 pm

At launch
Falcon 9 lifts off from Cape Canaveral.

Capitalism in space: SpaceX tonight successfully used its Falcon 9 rocket to launch four astronauts to ISS on its new Endurance capsule.

SpaceX now has three capsules in its manned fleet, Endeavour, Resilience, and Endurance. This was the company’s fifth manned launch, and its fourth for NASA. The crew will dock with ISS tomorrow in the early evening.

The company also successfully landed its first stage, which was also making its second flight.

The leaders in the 2021 launch race:

41 China
24 SpaceX
18 Russia
4 Northrop Grumman
4 ULA
4 Europe (Arianespace)

China now leads the U.S. 41 to 37 in the national rankings.

Viewing tonight’s Endurance launch with four astronauts

9:25 am

NASA has published an updated schedule for the launch tonight of four astronauts to ISS in SpaceX’s new Endurance Dragon capsule.

The launch now is targeted for no earlier than 9:03 p.m. EST Wednesday, Nov. 10, on a SpaceX Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The launch follows a successful return of the agency’s SpaceX Crew-2 mission.

The Crew Dragon Endurance is scheduled to dock to the space station at 7:10 p.m. Thursday, Nov. 11. Launch and docking coverage will air live on NASA Television, the NASA app, and the agency’s website.

You can also watch it on SpaceX’s website, as well as the embedded live stream below, which begins around 4 pm (Eastern).

This will be the fourth manned flight SpaceX has launched for NASA, the fifth overall using three spacecraft.

Endeavour undocking from ISS delayed one day; Endurance launch still set for November 10th

9:03 am

Because of high winds, the undocking of Endeavour from ISS was delayed from yesterday until today, with the landing now set for later this evening.

If conditions are favorable Monday, Crew-2 astronauts Shane Kimbrough, Megan McArthur, Akihiko Hoshide and Thomas Pesquet will enter their Crew Dragon capsule currently attached to the International Space Station and depart at 2:05 p.m. ET. Splashdown in one of seven potential landing sites off the Florida coast is expected about eight hours later at 10:33 p.m. ET.

The 24-hour delay from Sunday to Monday, however, didn’t impact the timing for another crew waiting to swap positions. Crew-3 astronauts Kayla Barron, Raja Chari, Thomas Marshburn, and Matthias Maurer are prepping for their Falcon 9 launch currently scheduled for no earlier than 9:03 p.m. Wednesday. Kennedy Space Center’s pad 39A will host.

Both NASA and SpaceX want to get Endeavour back to Earth, as it has already exceeded the six month time it is designed (at present) to stay in space.

Endeavour and crew to return to Earth tomorrow

9:28 am

UPDATE: The landing and launch have been delayed again because of weather, with the ISS crew now targeting a splashdown tomorrow, November 8th, and the new crew targeting a November 10th launch.

The four astronauts who were brought to ISS six months ago by the Dragon capsule Endeavour will now return to Earth early tomorrow, ahead of the next crew that is now scheduled to launch to ISS on November 10th on the Dragon capsule Endurance.

NASA’s SpaceX Crew-2 mission now is targeting a return to Earth no earlier than 7:14 a.m. EST Monday, Nov. 8, with a splashdown off the coast of Florida. The Crew Dragon spacecraft, named Endeavour, is scheduled to undock from the International Space Station at 1:05 p.m. Sunday, Nov. 7, to begin the journey home. NASA will preview the mission on Saturday, Nov. 6 and provide coverage Sunday of the mission on NASA Television, the NASA app, and the agency’s website.

The agency decided to flip the two events in order to make sure it could get Endeavour back to Earth before it exceeded its seventh-month life limit in space.

A reminder: Both the splashdown of Endeavour and the launch of Endurance will be run by a private company, SpaceX, with the government merely acting as customer. Every worker you see, except for the astronauts, will be employees of SpaceX, not NASA.

Astra proposes its own 13,000 satellite internet constellation

9:17 pm

Capitalism in space: Astra, the startup smallsat rocket company that has yet to successfully complete an orbital launch, has filed with the FCC a proposal to launch a 13,000 satellite constellation for providing internet services globally.

Astra said its satellites would be built in-house, and would be launched on Astra’s own rockets. The satellites would be sent into orbital altitudes ranging from 236 to 435 miles (380 to 700 kilometers), and would be equipped with propulsion systems to aid in collision avoidance and post-operational deorbiting.

Potential applications for Astra’s high-bandwidth connectivity would include communications services, environmental and natural resource applications and national security missions.

Though Astra could certainly launch many of these satellites itself, it is unlikely it launch them all with its small rocket. Thus, more launch business for other rocket companies!
