ISS spacewalk postponed because controllers had to maneuver station to avoid space junk

9:26 am

An American spacewalk to install new solar panels to ISS yesterday was suddenly scrubbed when ground controllers identified a piece of space junk that was going to fly within a quarter mile of the station.

While flight control teams were preparing for today’s U.S. spacewalk, updated tracking data on a fragment of Russian Fregat-SB upper stage debris showed a close approach to station. Based on this new data, flight control teams directed the crew to stop spacewalk preparations as the ground team stepped into procedures to perform a Pre-Determined Debris Avoidance Maneuver (PDAM.)

Russian controllers successfully used the engines on a docked Progress freighter today to complete the avoidance maneuver, firing those engines for 10 minutes and 21 seconds.

It appears the station was never in any danger.

Russians preparing replacement Soyuz for launch to ISS

8:57 am

ISS as of November 28, 2022
ISS after November 28, 2022 docking of unmanned Dragon freighter.
MS-22 is the Soyuz capsule that is leaking.

Though a final decision will not be made until the completion on December 27, 2022 of their investigation into the leak in the coolant system of the Soyuz capsule docked to ISS, the Russians have begun preparing a replacement Soyuz for launch.

A backup spacecraft to bring cosmonauts aboard the International Space Station (ISS) back to Earth will be prepared by February 19 and the spaceship is currently undergoing tests at the Baikonur spaceport, Roscosmos Chief Yury Borisov said on Monday.

That replacement Soyuz was supposed to launch in March, which means they can only accelerate its preparation by about a month. Assuming it is determined that the leaking capsule cannot be used safely as a lifeboat, this means that until February the station does not have its standard complement of lifeboats.

Should something happen that requires an immediate evacuation before February, it might be possible to get an extra three people into the two Dragon capsules presently docked to ISS, since each was designed to carry a maximum of six passengers, though generally four is considered their maximum capacity.

Temperature in leaking Soyuz capsule drops

9:45 am

According to Russia’s state-run press TASS, the temperature in its leaking Soyuz capsule on ISS has now dropped to between 50 to 54 degrees Fahrenheit.

The language of the report suggests this temperature drop was the result of actions by Russia’s mission control, but that is decidedly unclear. With the thermal control system now depressurized, the capsule’s temperature could fluctuate a lot, depending on whether it is in shadow or sunlight, a condition dependent on the overall orientation of ISS itself.

A second TASS report today said that two Russian working groups are reviewing the data, and will decide around December 27th what the next step will be, including the possibility of launching a Soyuz capsule unmanned to replace this capsule.

“I believe that at the end of December, somewhere on the 27th [of December], specialists – and now two working groups have been set up – will decide on how we will resolve this situation,” [Yuri Borisov] the Roscosmos head, said in an interview with the daily Izvestia.

There is plenty of time for making decisions and “there is no hurry,” Borisov stressed.

What Borisov was really saying is that there is no reason to panic, but action must be taken without unnecessary delay.

Russians test thrusters on leaking Soyuz

9:28 am

In the continuing investigation into the leak of coolant from a Soyuz capsule docked to ISS, Russian engineers yesterday tested the capsule’s thrusters, finding they functioned as normal.

As part of the ongoing evaluation and investigation, Roscosmos flight controllers conducted a successful test of the Soyuz MS-22 thrusters at 3:08 a.m. EST Friday, Dec. 16. The systems that were tested were nominal, and Roscosmos assessments of additional Soyuz systems continue. Temperatures and humidity within the Soyuz spacecraft, which remains docked to the Rassvet module, are within acceptable limits.

The highlighted words have been the Russians’ way of downplaying a serious concern. According to their own data, the temperatures in the capsule have now risen to 86 degrees Fahrenheit, which though entirely safe is higher than normal for within habitable spacecraft. Should those temperatures continue to rise, it will start to become a problem.

One solution would be circulate cooler air from the rest of the station. I suspect this is possible with equipment on board, but do not know for sure.

Right now however it surely appears that it would likely not be wise to return its crew to Earth in this capsule, and that a replacement will be required.

Russian official: Soyuz leak possibly caused by micrometeorite hit

9:17 am

According to Sergei Krikalev, who heads Roscosmos’ manned program, the leak of coolant from the Soyuz capsule docked at ISS could have been caused by a micrometeorite hit.

Sergei Krikalev, a veteran cosmonaut who serves as the director of crewed space flight programs at Roscosmos, said a meteorite striking one of external radiators of the Soyuz MS-22 capsule could have caused the coolant to escape.

The malfunction could affect the performance of the capsule’s coolant system and the temperature in the equipment section of the capsule but doesn’t endanger the crew, Krikalev said in a statement.

Krikalev said Russian flight controllers were assessing the situation and following temperature indicators on the Soyuz. “There have been no other changes in parameters on the Soyuz spacecraft and the station, so there is no threat for the crew,” he said.

The “equipment section of the capsule” is its service module, not its habitable orbital module or descent module.

Krikalev, the first Russian to fly on the space shuttle and occupy ISS, is a generally very reliable source. He is speculating, but not wildly but based on what is so far known. The upcoming inspection of the Soyuz using an ISS robot arm will soon tell us whether he is right or not. Krikalev also said that the inspection will tell them whether this capsule can be used to return its astronauts to Earth.

Soyuz manned capsule docked to ISS is apparently leaking something

9:13 pm

A spacewalk today was cancelled when it was suddenly noticed that some unknown substance was leaking from one of the Soyuz manned capsules docked to ISS.

During preparations for this evening’s planned spacewalk by Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin, ground teams noticed significant leaking of an unknown substance from the aft portion of the Soyuz MS-22 spacecraft docked to the Rassvet module on the International Space Station. The spacewalk has been canceled, and ground teams in Moscow are evaluating the nature of the fluid and potential impacts to the integrity of the Soyuz spacecraft, which carried Prokopyev, Petelin, and NASA astronaut Frank Rubio into space after launching from the Baikonur Cosmodrome in Kazakhstan on Sept. 21.

The big question is whether this leak will impact the capsule’s function as a lifeboat or a return vehicle for the three astronauts it brought into space. If so, then an empty manned capsule needs to be launched, either by the Russians or SpaceX, though if the latter someone would have to pay the cost.

NASA awards Collins contract to build spacesuits for space station spacewalks

9:22 am

Capitalism in space: NASA yesterday awarded Collins Aerospace a $97.2 million contract to build spacesuits for the agency’s future space station spacewalks.

In June NASA had picked Collins and Axiom as the vendors who would build spacesuits for the agency. In September it purchased its its first Artemis Moon spacesuits from Axiom. This new contract has NASA buying its first new space station suits from Collins.

In both cases, the companies own their designs, and can thus sell them to the other private space stations presently under construction.

This contract award follows NASA abandonment of its own failed spacesuit effort, which spent fourteen years and a billion dollars and produced nothing.

Dragon freighter docks with ISS

9:22 am

ISS as of November 28, 2022

Capitalism in space: An unmanned Dragon freighter successfully docked with ISS yesterday, bring with it 7,700 pounds of cargo, including two new solar arrays for the station.

Two International Space Station Roll-Out Solar Arrays, or iROSAs, launched aboard SpaceX’s 22nd commercial resupply mission for the agency and were installed in 2021. These solar panels, which roll out using stored kinetic energy, expand the energy-production capabilities of the space station. The second set launching in the Dragon’s trunk once installed, will be a part of the overall plan to provide a 20% to 30% increase in power for space station research and operations.

These arrays, the second of three packages, will complete the upgrade of half the station’s power channels.

The graphic to the right shows the station as of today, with six different spacecraft docked to six different ports. No wonder there is a significant limit to the number of private missions that can fly to ISS. The needs of the station, as dictated by the international partnership of governments that run it, too often fill those ports.

This limitation will begin changing when Axiom launches its first module for ISS in about two years, followed soon thereafter by the launch of a number of other private independent stations by different American companies.

SpaceX’s Falcon 9 successfully launches Dragon freighter to ISS

12:34 pm

SpaceX today successfully used its Falcon 9 rocket to launch a Dragon freighter to ISS.

The first stage landed successfully on a drone ship in the Atlantic, completing its first flight, only the third time this year out of 54 total launches that SpaceX had to use a new first stage. All other launches were with reused boosters.

The Dragon freighter is scheduled to dock with ISS at 7:30 am (Eastern) tomorrow.

The leaders in the 2022 launch race:

54 SpaceX
52 China
19 Russia
9 Rocket Lab
8 ULA

The U.S. now leads China 78 to 52 in the national rankings, but trails the rest of the world combined 81 to 78.

Hungary to pay $100 million to Axiom for astronaut mission to ISS

12:35 pm

Hungary has budgeted $100 million to fly a Hungarian astronaut on a 30 day mission to ISS, arranged as a private mission though the American space company Axiom.

“This is a program which is being carried out with the cooperation of the American company Axiom Space and its extent is $100 million,” said [Péter Szijjártó, Hungarian foreign minister,] of the initiative. “This will end up in a 30-day-long research mission of a Hungarian astronaut with three other astronauts at the end of 2024 or beginning of 2025, depending on what time NASA confirms access to the International Space Station.”

NASA has yet to award missions to Axiom Space beyond its Ax-2 mission scheduled for the spring of 2023, but is evaluating proposals for two private astronaut missions that could include an Axiom Space flight in that timeframe.

It is clear that negotiations for arranging this mission between Axiom, NASA, and Hungary are on-going. Based on Szijjártó’s description, it is possible that the Hungarian astronaut could fly on a dedicated private Axiom mission to ISS, with two other paying passengers and an Axiom commander, or fly as an extra passenger on a normal ISS crew rotation flight. Furthermore, the ’24 or ’25 launch date suggests the vehicle might not be a Dragon capsule. By that time Boeing’s Starliner should be operational, thus giving Axiom and NASA an alternative. That time frame also corresponds to about when Axiom hopes to launch and dock its own module to ISS.

Nor is Hungary the only foreign country that has signed a deal with Axiom for a manned flight. Both Turkey and Saudi Arabia have agreements as well.

All told, the biggest obstacle right now to this new market is the number of ports on ISS. It seems Axiom has a strong incentive to get its own module launched and attached to ISS as soon as possible, if only to increase the docking ports available for these flights.

Japan to stay on ISS to 2030 in exchange for an astronaut flight to Gateway

9:26 am

NASA yesterday announced that Japan has agreed to remain on ISS through 2030, the first international partner to do so, and in exchange will get a Japanese astronaut flight to the Lunar Gateway station.

Under the Gateway Implementing Arrangement, NASA will provide an opportunity for a Japan Aerospace Exploration Agency (JAXA) astronaut to serve as a Gateway crew member on a future Artemis mission. This formally represents the first commitment by the U.S. to fly a Japanese astronaut beyond low-Earth orbit aboard NASA’s Space Launch System (SLS) rocket and Orion spacecraft.

I remain very doubtful in the long run these flights will occur on SLS, which simply cannot launch frequently enough to make the entire program viable. More likely with time the rocket will be replaced by other commercial carriers.

Cygnus successfully berthed at ISS

9:06 am

Cygnus approaching ISS on November 9, 2022

Despite on of its two solar panels only partly deployed, astronaut Nicole Mann was able to use the robot arm on ISS to grab Northrop Grumman’s Cygnus freighter and bring it into its port, where ground engineers successfully berthed it.

The image to the right is a screen capture from NASA TV as Cygnus approached. You can see the problematic panel at the bottom. Though it has folded out from its initial stored position, it has not opened up fully.

The freighter will stay docked to ISS until late January, during which the crew will unload about four tons of cargo and then fill it with garbage before sending it to burn up over the ocean. We should expect NASA and Northrop Grumman to also plan a spacewalk to not only inspect the panel to figure out what failed, but to see if it can still be deployed.

Cygnus freighter continues to target ISS rendezvous tomorrow

5:19 pm

Though one of its two solar panels remains undeployed, engineers and Northrop Grumman and NASA have proceeded with four engine burns so as to rendezvous with ISS tomorrow, November 9th, with arrival in the early morning hours.

Expedition 68 NASA astronaut Nicole Mann will capture Cygnus with the station’s robotic arm, with NASA astronaut Josh Cassada acting as backup. After Cygnus capture, ground commands will be sent from mission control at NASA’s Johnson Space Center in Houston for the station’s arm to rotate and install it on the station’s Unity module Earth-facing port.

According to this NASA update, it appears that NASA managers are confident that the stuck solar panel is not blocking the grapple point, preventing the arm from grabbing the capsule. At the same time, the wording in the update is just a bit vague, and also suggests that before this capture occurs they will be inspecting Cygnus very carefully.

One of two solar panels on Cygnus capsule fails to deploy

3:46 pm

The failure of one of the two solar panels on Northrop Grumman’s Cygnus capsule to deploy today shortly after launch might cause some issues with getting the spacecraft docked to ISS.

Northrop Grumman has reported to NASA that Cygnus has sufficient power to rendezvous with the International Space Station on Wednesday, Nov. 9, to complete its primary mission, and NASA is assessing this and the configuration required for capture and berthing.

The capsule does not dock directly with the station, but is instead grabbed by a robot arm, which then brings it into its port. The grapple point that the arm uses is on the end where the solar panels are, with the docking port at the capsule’s other end. What is not presently clear is whether that point is blocked by the undeployed panel.

Northrop Grumman’s Antares rocket launches Cygnus freighter to ISS

8:57 am

Capitalism in space: Early this morning Northrop Grumman’s Antares rocket successfully completed its second launch this year, lifting off from Wallops Island and carrying a Cygnus freighter for ISS.

This launch is also the next-to-last for this version of Antares. Northrop Grumman is using up the last few first stages built in the Ukraine that use Russian engines, after which it will send the next three Cygnus capsules into space using SpaceX’s Falcon 9. It hopes to introduce a new Antares using a Firefly first stage following that.

The leader board in the 2022 launch race remains the same:

51 SpaceX
48 China
19 Russia
9 Rocket Lab

American private enterprise still leads China 73 to 48 in the national rankings, but trails the rest of the world combined 76 to 73.

NASA delays first manned Starliner mission again

9:53 am

NASA today announced that it has rescheduled the first manned demo mission of Boeing’s Starliner capsule to ISS from February to April, 2023.

The agency attributes the two month delay to scheduling conflicts with other visiting spacecraft at ISS. This might be true, but it also could be that Boeing wanted a little extra time to finish out the work it still needs to do to fix the anomalies that occurred on the unmanned demo mission, as well preparing the new capsule for launch.

This flight will carry two astronauts to ISS for about two weeks. The press release also noted this interesting tidbit:

The previously flown crew module, named Calypso, will be connected to a new service module later this year.

Apparently Boeing has decided to give names to these capsules, like SpaceX has. It also appears that the company and NASA are satisfied enough with the condition of the capsule after flying the unmanned demo flight to use it again for a manned mission.

Two Saudi passengers to fly on Axiom’s second commercial flight to ISS

10:21 am

According to one NASA official, Axiom now plans on launching two as yet unnamed Saudi passengers on AX-2, its second commercial flight to ISS scheduled to launch in May 2023 on a Dragon capsule.

The names of the two Saudis on the flight have not been released, she said, but that “we are working very hard with them on training already.” A slide for her presentation noted the two would be named after formal approval by the ISS program’s Multilateral Crew Operations Panel. That slide also stated that crew training for the mission started Oct. 17.

The Saudi Space Commission and Axiom Space separately announced Sept. 22 plans to fly two Saudi citizens on a future Axiom Space mission. However, while it was widely rumored the two would fly on Ax-2, neither announcement stated a specific mission. The Saudi statement said that one of the two people would be a woman but did not disclose how the astronauts would be selected.

Neither Axiom nor the Saudis have revealed the ticket price, though it probably runs somewhere in the range of $20 to $50 million per ticket, based on past known purchase prices by NASA and others.

Russian government okays ISS partnership through ’27

9:08 am

The Russian government yesterday approved an order allowing Roscosmos to continue to send its astronauts and spacecraft to ISS through 2027.

“The expected results are as follows: transport and technical support for the Russian segment of the International Space Station in 2023-2027, including the delivery to the station and return to Earth of Russian crews, as well as the delivery to the ISS of fuel and cargo crucial to maintaining the ISS in flight and the implementation of a long-term program for authorized works,” the instruction says.

Putin’s government is essentially admitting that it will not be able to launch its own space station by ’27, so it has to stay on ISS because that’s all it has. Whether ISS can last that long, considering the somewhat delicate state of some of the oldest Russian modules, remains unclear.

The American private stations should all be coming on line in the years from 2024 to 2030, so it appears the U.S. is covered. What Russia will do however remains unknown. I suspect it will be far more difficult politically for it to buy time on the American private stations, compared to Europe. But if it doesn’t get its own station launched, buying time might be its only option, assuming of course the U.S. government allows it to do so. And considering that other Russian officials are threatening America’s private space assets, the likelihood that Russia will be allowed on future American space stations seems remote indeed.

European nations struggle with the new private commercial space station concept

8:59 am

The European partners that have been doing research and work on ISS are now struggling to figure out their future on the multiple new private commercial space stations American private enterprise is now building to replace ISS.

The ISS today relies extensively on barter arrangements among participating agencies, providing services to cover their share of operations of the station. Such arrangements are unlikely to work for commercial stations, however. “We need to find a new way of cooperating,” said Nicolas Maubert, space counselor at the French Embassy in the U.S. and representative of the French space agency CNES in the U.S., citing the challenges of extending current barter arrangements to commercial stations. “We need to put on the table every option.”

The simplest approach — direct payments from space agencies to the companies operating commercial stations — could face political obstacles. “The taxpayers in Europe don’t want to pay directly to private American companies,” he said. [emphasis mine]

The highlighted words illustrate the fundamental problem. Europe on ISS has been for decades like a welfare queen. It has gotten access to space mostly free, since what it has offered in exchange for that access has never come close to matching what its work on ISS cost American taxpayers. Now that it will have to pay for that access in real dollars, some of its member nations are balking.

France for example still wants a free ride. Maubert suggested that Europe build its own space station, which means France wants its other ESA partners to help pay for the station that France wants to use.

I say, too bad. The costs on the private stations — built for profit and efficiency — will be far less that ISS. That cost will also be far far less than anything Europe might spend trying to build its own government station. Europe should bite the bullet and pay up. It won’t regret it.

  • Protein crystal experiment to be launched on next Cygnus freighter to ISS

    • The tweet includes a cool picture of a protein crystal. From the experiment’s abstract:

    The Ring Sheared Drop investigation examines the formation and growth of amyloids and fibrils without the complications associated with the solid walls of a container, because in microgravity, surface tension provides containment of the liquid. Fibrous, extracellular protein deposits found in organs and tissues, amyloids are associated with neurodegenerative diseases such as Alzheimer’s. Results could contribute to better understanding of these diseases as well as to development of advanced materials.

    Forgive me if I am skeptical about this work. Protein crystal experiments have been going on on ISS now for more than two decades, without any clarity whether any have actually turned out useful on Earth. When I have seen presentations about them, I have repeatedly wondered if this isn’t more about creating papers and funding, not actual new knowledge that has a useful application.

    If I am wrong I would love to be educated otherwise.

ISS dodges space junk from Russia’s November 2021 anti-satellite test

9:46 am

In order for ISS to avoid one of the approximately 585 pieces of space junk still in orbit that were produced when Russia destroyed its defunct Cosmos 1408 satellite in a November 2021 anti-satellite test, engineers fired the engines of a docked Progress freighter yesterday for just over five minutes.

Without the burn the debris would have flown within three miles of the station, too close for comfort or anyone’s margin of error.

According to a report in September, of these 585 pieces, most will burn up in the atmosphere by ’25, with only 38 pieces left afterward to pose a threat to other operating satellites and manned spacecraft.

NASA approves use of American spacesuits for spacewalks after investigation

10:14 am

NASA this week gave approval to the resumption of spacewalks on ISS, using its American spacesuits, following its investigation into a March incident where one astronaut’s spacesuit became somewhat water-logged.

The agency has now completed a review of the incident, finding that it was not a leak caused by hardware issues. Instead, the water was condensation caused by high levels of astronaut exertion and the cooling setting on Maurer’s extravehicular mobility unit (EMU) spacesuit, NASA officials said.

Though NASA was somewhat vague about the solution, it appears it has simply told astronauts to adjust the cooling setting of their suits to prevent condensation within the suits.

These American suits are very complicated to use, and very expensive. The agency has contracted out for new suits from private companies, but it will be very instructive to see what SpaceX comes up with for the spacewalk suits it is making for the private commercial manned Polaris Dawn mission in the spring of 2023.

Watching return of ISS crew on Freedom

9:40 am

The SpaceX manned capsule Freedom has undocked from ISS, carrying three astronauts completing a six month mission, with a scheduled splashdown planned for 4:50 pm (Eastern) off the western coast of Florida.

I have embedded NASA’s live stream below, for those that wish to watch. Note that though NASA inserts itself into this event, once the spacecraft has left ISS everything — including all workers involved in splashdown operations — is solely under the supervision of SpaceX, with NASA’s participation only that of a customer, albeit a very powerful one. This is a capsule and splashdown designed, built, run, and most important, owned by a private American company, not the government.

Will Tom Cruise ever actually shoot a movie in space?

10:17 am

Capitalism in space: According an interview last week from Donna Langley, chairman of Universal Film Entertainment Group, the company is arranging for Tom Cruise to film scenes of a movie on ISS, where Cruise will also be the first non-professional to do a spacewalk.

“That’s the plan. We have a great project in development with Tom that does contemplate him doing just that,” she said, “taking a rocket up to the space station and shooting and hopefully being the first civilian to do a spacewalk outside of the space station.”

She said the film request came from Cruise directly and that he is in close collaboration with director Doug Liman, who previously worked with Cruise in 2014’s “Edge of Tomorrow” and is also known for “The Bourne Identity” franchise, “Mr. and Mrs. Smith” and “Jumper.”

This claim might be true, but producers associated with Cruise have been making such claims now for three years, none of which have come even close to happening. I am sure the project is being discussed, and even pushed hard, but based on what has actually happened, this announcement could simply be a way to generate buzz for Cruise’s next film, whether or not he flies.

Nonetheless, I fully believe that Cruise is the source of this idea, and wants to do it, given his habit of doing his own stunts in his movies.

Endurance docks at ISS

9:16 am

Like clockwork SpaceX’s Endurance capsule successfully docked at ISS yesterday, delivering four astronauts to the station for a six month mission.

The most interesting aspect of this launch and crew is Russian Anna Kikina.

Kikina is the first Russian to fly aboard a U.S. spacecraft in nearly 20 years. She and Rubio were launched under a new agreement between NASA and Roscosmos, the Russian space agency, that ensures at least one astronaut or cosmonaut is always aboard the space station even if a Crew Dragon or Soyuz is forced to depart early, taking its crew with it.

Without the seat-swap arrangement, a medical emergency or some other major problem could leave an all-Russian or all-NASA crew aboard without the expertise to operate the other nation’s systems.

The agreement had been stalled almost entirely by the former head of Roscosmos, Dmitry Rogozin. He is now gone however, sent by Putin to take over the fake occupation government in parts of the Ukraine. It appears his bellicose manner, that caused the loss of a billion dollars in launch contracts with OneWeb, was more than even Putin could handle.

With him gone, the new head of Roscosmos, Yuri Borisov, quickly finalized this astronaut barter deal. He has also publicly acted to try to ease tensions between the U.S. and Russian space agencies.

Important Roscosmos official endorses continuing cooperation with US in space

12:28 pm

In a clear sign of the distinct change in atmosphere since the removal of Dmitry Rogozin as head of Roscosmos, the executive director of human space flight programs at Roscosmos, Sergei Krikalev, yesterday endorsed the longstanding cooperation between the U.S. and Russia in space.

Krikalev’s comments came after the launch yesterday of Endurance with one Russian astronaut as part of its four-person crew.

At a briefing after the Oct. 5 launch of the Crew-5 mission from the Kennedy Space Center, Sergei Krikalev, executive director of human space flight programs at Roscosmos, emphasized long-running cooperation between the United States and Russia in civil space, cooperation that has been strained since Russia’s invasion of Ukraine in February.

“We just continue what we started many years ago in 1975 when the Apollo-Soyuz crew worked together, and now we continue our cooperation,” he said after mentioning a “new phase of cooperation” with the exchange of seats between NASA and Roscosmos.

To understand the importance of Krikalev’s comments, you must also understand the context. First, Krikalev is a very significant figure in the history of Russia. He was called the last Soviet citizen, having been stranded on Mir an extra few months when the Soviet Union fell in 1991. Then he was the first Russian to fly on the shuttle, followed later by being on the first mission to ISS, when it was only two modules.

Since his retirement as an active astronaut, he has become the man in charge of Russia’s manned program, where he clashed with Rogozin several times over policy. His opposition to Rogozin almost certainly was a factor in Rogozin’s removal.

Krikalev’s endorsement of continuing the U.S-Russian partnership only cements that partnership, especially because Krikalev himself is a dyed-in-the-wool communist at heart. At least, he said so emphatically when I interviewed him at length in 2003 for Leaving Earth. I doubt his mind has changed in this matter, though his relentless honesty as an engineer has probably shaken his dedication to that failed ideology in subsequent years.

Nonetheless, his standing in Russia gives any statement he makes great weight. Expect more efforts by the Russians to ease tensions with the U.S., though their chances of success will be limited as long as Russia is continuing its unprovoked invasion of the Ukraine.

SpaceX successfully launches astronauts to ISS

9:40 am

Capitalism in space: SpaceX this morning successfully launched two NASA astronauts, one Japanese astronaut, and one Russian astronaut into orbit for a mission to ISS, with the docking scheduled for tomorrow.

The capsule, Endurance, is making its second flight. This was SpaceX’s eighth manned launch. The first stage, making its first fight, landed successfully on the drone ship in the Atlantic. This was the first new first stage launched since May 2022, and only the second this year. All other launches in 2022 were completed using SpaceX’s existing fleet of boosters. The company also continues to hold to the pattern of last year for maintaining that fleet, by adding two new boosters each year.

That this achievement is now becoming as routine as SpaceX’s unmanned launches proves the company’s success. And SpaceX did it in less than a decade, something NASA with its government-built shuttle was never able to accomplish.

The leaders in the 2022 launch race:

44 SpaceX
41 China
12 Russia
7 Rocket Lab
7 ULA

American private enterprise now leads China 63 to 41 in the national rankings, and the entire world combined 63 to 61.
