Soyuz safely returns three astronauts from ISS

9:22 am

A Russian Soyuz capsule today safely landed in Kazakhstan, completing an eight-month mission to ISS by two Russians and one American.

NASA astronaut Chris Williams and Roscosmos cosmonauts Sergey Kud‑Sverchkov and Sergei Mikaev wrapped up a 241‑day mission, orbiting Earth 3,856 times and traveling more than 102 million miles. Soyuz MS‑28 launched and docked with the International Space Station on Nov. 27, 2025. This flight marked the first mission for Williams and Mikaev and the second for Kud‑Sverchkov.

After routine post‑landing medical checks, recovery teams will fly the crew by helicopter to Karaganda, Kazakhstan. Williams then will board a NASA aircraft bound for the agency’s Johnson Space Center in Houston.

Because of financial problems resulting from its invasion of the Ukraine, Russia has increased the length of its missions to ISS from six months to eight, so that it only has to do three manned launches every two years, instead of four. Though Russia did this to save money, it has the benefit of making eight month missions routine, allowing for better research on the long term effects of weightlessness.

Three launches, two by SpaceX and one by Russia

8:24 am

The global rocket industry completed three launches since last night.

First, SpaceX placed 27 Starlink satellites into orbit, its Falcon 9 lifting off last night from Vandenberg Space Force Base in California. The first stage (B1093) completed its 15th flight (29 days after its previous mission), landing on a drone ship in the Pacific.

SpaceX then followed up with a morning launch, placing 29 more Starlink satellites in orbit, its Falcon 9 rocket lifting off from Cape Canaveral Space Force Station in Florida. The first stage (B1080) completed its 28th flight (32 days after its previous mission), landing on a drone ship in the Atlantic. This launch tied this booster for ninth place with the space shuttle Columbia in the rankings for the most reused launch vehicles.

Finally, Russia successfully placed one American and two Russian astronauts into orbit, its Soyuz-2 rocket lifting off from Russia’s Baikonur spaceport in Kazakhstan. Their Soyuz capsule docked with the Prichal module on the Russian half of ISS several hours later, beginning an eight month mission for this crew.

The leaders in the 2026 launch race:

85 SpaceX
45 China
10 Rocket Lab (plus two suborbital HASTE launches)
9 Russia

For the third straight year SpaceX leads the entire world combined in total launches, 85 to 78.

Russia will charge about $27 million for future tourist flights

9:26 am

According to Dmitry Bakanov, head of Roscosmos, it will likely charge about two billion rubles, about $27 million, to fly tourists in space in the future.

The cost of a space tourist trip will be approximately 2 billion rubles, Roscosmos CEO Dmitry Bakanov said in an interview with VK Video on the sidelines of the St. Petersburg International Economic Forum. “It’s still an expensive project. The costs include the rocket divided by the number of participants. There must be two professionals, because they can guide it, so it’s about two billion rubles,” Bakanov noted.

The report of his remarks in Russia’s state-run press is not entirely clear as to whether this number is the price per tourist, the price for the entire flight, or Roscosmos’ cost for the flight, excluding its mark-up. Assuming it is the price for the entire flight, it is about a quarter of what Russia was charging NASA during the last few ferrying trips to ISS before SpaceX’s Dragon capsules became operational. This makes sense, since Russia was milking NASA for as much as it could get during those last flights. Future private tourists won’t have as much money as a spend-thrift government, so Roscosmos is now forced to charge a realistic price.

Three astronauts return from ISS in Soyuz capsule

9:09 am

Early today one American and two Russians safely returned to Earth, their Soyuz capsule touching down on the plains of Kazakhstan after spending more than eight months on ISS.

NASA astronaut Jonny Kim returned to Earth on Tuesday alongside Roscosmos cosmonauts Sergey Ryzhikov and Alexey Zubritsky, wrapping up an eight-month science mission aboard the International Space Station to benefit life on Earth and future space exploration. They made a safe, parachute-assisted landing at 12:03 a.m. EST (10:03 a.m. local time), southeast of Dzhezkazgan, Kazakhstan, after departing the space station at 8:41 p.m. on Dec. 8, aboard the Soyuz MS-27 spacecraft.

Over the course of 245 days in space, the crew orbited Earth 3,920 times, traveling nearly 104 million miles. They launched to the space station on April 8. This mission marked the first spaceflight for both Kim and Zubritsky, while Ryzhikov completed his third journey to space, logging a total of 603 days in space.

There remains on ISS one Soyuz, with its crew of three, with a planned return in July 2026. Getting its replacement crew launched however remains an unknown right now because of the damage to the Soyuz-2 rocket launchpad in Baikonur that occurred when they were launched two weeks ago. Roscosmos has provided no public updates about its plans to fix the pad or replace it, and until such plans are revealed, the Russians have no ability to launch any further manned missions.

This is why I speculated earlier that the present Soyuz crew might be starting an extended mission, awaiting repairs to the launchpad.

All eight ports on ISS occupied for the first time; Longest manned mission about to start?

9:56 am

ISS as presently configured
ISS as presently configured. Click for original.

For the first time in its more than quarter century history, all eight docking ports on ISS are occupied, as shown in the graphic to the right.

For the first time in International Space Station history, all eight docking ports aboard the orbital outpost are occupied following the reinstallation of Northrop Grumman’s Cygnus XL cargo spacecraft to the Earth-facing port of the station’s Unity module. The eight spacecraft attached to the complex are: two SpaceX Dragons, Cygnus XL, JAXA’s (Japan Aerospace Exploration Agency) HTV-X1, two Roscosmos Soyuz crew spacecraft, and two Progress cargo ships.

This milestone follows the reattachment of the Cygnus XL spacecraft, supporting the Northrop Grumman-23 commercial resupply services mission for NASA, which was removed last week by the robotics officer at the agency’s Mission Control Center in Houston using the space station’s Canadarm2 robotic arm. The Cygnus XL movement was coordinated between NASA, Northrop Grumman, and Roscosmos to provide appropriate clearance for the arriving crewed Soyuz MS-28 spacecraft on Nov. 27.

Cygnus will remain attached to the orbiting laboratory until no earlier than March 2026, when it is scheduled to safely depart and dispose of up to 11,000 pounds of trash and unneeded cargo when it harmlessly burns up in Earth’s atmosphere.

This situation will not last of course, and in fact it may never happen again before the station is retired around 2030. First, Cygnus will leave in March. Second, one Russian Soyuz capsule will leave shortly, as the presence of two simply indicates a crew rotation is underway.

Third, it is presently unclear when the Russians will be able to launch further Soyuz or Progress capsules. » Read more

Roscosmos forced to replace next manned Soyuz capsule due to damage during test

11:38 am

Russia’s space agency Roscosmos has replaced the Soyuz capsule it was going to use in the next manned mission to ISS, scheduled for launch in late November, because of “major damage” the capsule experienced during normal pre-flight testing.

[D]uring routine post-production tests at ZEM’s Checkout and Test Facility, KIS, Vehicle No. 759 reportedly suffered major damage to its thermal protection system, which could not be repaired in time for the Expedition 74 launch at the end of 2025. According to one source, quoting an officer within the military certification service, Voennaya Priemka, which traditionally oversees quality control in the Russian rocket and space industry, the ship’s main thermal control heat shield, attached to the base of the Descent Module, was accidentally jettisoned, perhaps by a stray signal triggering the pyrotechnic bolts, connecting the Frisbee-shaped structure to the capsule. According to another source, the thermal layers of the shield peeled off, as a result of botched thermal tests.

That Russia can quickly swap capsules this late in the game speaks well of its Soyuz capsule manufacturing process. It doesn’t just build one or two capsules, it has an assembly line.

That the capsule was damaged during the test however once again raises questions about the overall quality control within the Russian space industry, as well as the reliability of its workforce. It has been building Soyuz capsules now for more than a half century, during which it has steadily implemented upgrades along the way. For there to be “a stray signal triggering the pyrotechnic bolts” during routine testing is disturbing. The circumstances are too similar to the earlier sabotage to both Progress and Soyuz capsules, where the evidence suggested someone on the ground had drilled holes in their hulls prior to launch, then patched them to hide their existence until later while in orbit.

Under Putin the living wages of Russian engineers has suffered. It remains a distinct possibility that there are more than a few malcontents within Roscosmos willing to do such stuff. That Roscosmos investigated the previous sabotage, claimed it identified the cause, but refused to release any information about its conclusions, suggests strongly that this is what what happened in those earlier cases. This new incident in turn raises the possibility now of further sabotage.

It once again is critical that the U.S. get out of its space station partnership with Russia as soon as possible. There are too many known and unknown risks.

Soyuz safely returns three astronauts from ISS

9:42 am

A Russian Soyuz capsule successfully landed in Kazakhstan this morning, bring two Russians and one American back to Earth after a seven month mission to ISS.

The American on board, Don Petit, also celebrated his 70th birthday today, completing his fourth mission in space. According to the article at the link, he did not do well upon landing, requiring significant aid to exit the capsule. The picture released by NASA of him being carried to the medical tent shows him smiling with a thumbs up, but he is clearly unable to walk at this point on his own. That fact by itself is not significant, because many astronauts after missions lasting longer than six months need aid upon return. It does indicate however that this flight is almost certainly Petit’s last one. As that NASA release it notes he “is doing well and in the range of what is expected for him following return to Earth.”

Russians launch three astronauts to ISS

2:20 pm

The Russians today successfully launched three astronauts to ISS, its Soyuz-2 rocket lifting off from Baikonur in Kazakhstan.

The Soyuz is scheduled to dock with ISS on March 25, 2024. The Russian and Belarus astronauts will stay on board ISS for about two weeks, returning to Earth on an Soyuz-2 capsule that is presently docked to ISS, taking with them an American who has just completed six months in space. The American on today’s launch will now start her own six month mission, and will return in September with two Russian astronauts who are presently on a year long mission, one of whom will likely set a new duration record for a woman.

The leaders in the 2024 launch race:

28 SpaceX
12 China
4 Rocket Lab
4 Russia

American private enterprise still leads the rest of the world combined in successful launches 33 to 22, while SpaceX remains ahead of the entire world, including American companies, 28 to 27.

China Long March 2D launches “group of satellites”; Russia scrubs manned Soyuz launch

8:45 am

China today successfully launched what it simply labeled as “a group of satellites”, its Long March 2D rocket lifting off from its Jiuquan spaceport in the northwest of China.

No other useful information was released about the payloads. Nor was there any word as to the crash site of the rocket’s first stage, which uses toxic hypergolic fuels and landed somewhere in China.

Meanwhile in Russia a launch of a Soyuz-2 rocket carrying three astronauts to ISS was aborted at about T-20 seconds for reasons that as yet remain unclear. According to NASA the next launch opportunity is March 23, 2024.

The leaders in the 2024 launch race:

27 SpaceX
12 China
4 Rocket Lab
3 Russia

American private enterprise still leads the rest of the world combined in successful launches 32 to 21, while SpaceX remains ahead of the entire world, including American companies, 27 to 26.

Russia and NASA agree to extend ISS astronaut exchanges on each other’s spacecraft through 2025

9:01 am

Russia and NASA have agreed to extend their barter deal through 2025, whereby each nation sends astronauts to ISS periodically on the other nation’s rockets and capsules.

This is a barter deal, with no exchange of money. The fundamental idea is to make sure astronauts on board ISS understand how the capsules from each nation operate in case of emergency. Russia had initially resisted signing such a deal after SpaceX began providing NASA its Dragon capsules and Falcon 9 rocket to get astronauts to ISS. It said this was because it did not trust SpaceX’s technology, but I suspect Roscosmos was also hoping to squeeze some cash from NASA as it was no longer being paid to fly U.S. astronauts on its Soyuz rocket and capsule. That attempt was futile. For numerous political reasons there was no way NASA was going to pay Russia anything in this barter deal.

Russia then signed on, and will keep extending this agreement until the day ISS is retired, or it finally launches its own station (something that is becoming increasingly unlikely).

Three astronauts return to Earth safely, completing 371 day mission

9:13 am

One American, Frank Rubio, and two Russians, Sergey Prokopyev and Dmitri Petelin, early today safely returned to Earth in their Russian Soyuz capsule, completing the longest mission yet on ISS, 371 days, and the third longest human mission ever.

The mission was the longest by accident. It was originally supposed to be a standard six month tour, but was extended to a year when the Soyuz capsule they came in developed a leak in its coolant system and had to be replaced.

The previous record for an American in space of 355 days was set by Mark Vande Hei last year. This new year-long mission is only exceeded by two Russian missions on Mir, Valeri Polykov’s 439 day mission in 1994-1995, and Sergei Avdeyev’s 381 day mission in 1998-1999.

Frank Rubio’s flight to ISS will exceed a year, setting a new American record

10:25 am

Frank Rubio
Frank Rubio

Initially, Frank Rubio’s first flight in space was intended to be a standard six month mission on ISS. Launched on September 21, 2022 on a Soyuz-2 rocket inside a Soyuz capsule, the plan was for him and his two crewmates to return in March, 2023.

Then their Soyuz capsule developed a leak in its coolant system in December 2022. Not knowing if it was safe to use this capsule with humans inside, a replacement unmanned Soyuz capsule was launched by the Russians to ISS in February 2023, with the leaking Soyuz capsule brought back unmanned earlier this week.

The Russians however decided that this new capsule, designed for a six month mission, would stay in orbit for six months, so that it would be used to its planned capability. This decision also hinged on the lack of a new crew arriving on this new capsule. If it brought Rubio and his crew home earlier, ISS would be short three crew members for at least several months.

The planned return date, September 27, 2023, now means that Rubio’s mission will be at least 371 days long, making him the first American to fly a full year in space. Previously NASA falsely touted Scott Kelly’s 340-day mission as a year-long mission, when it never was. Later, Mark Vande Hei’s mission, also launched on a Soyuz, was extended to 355 days, still just short of a year, because the Russians wanted to send a film crew to ISS and return them on the capsule which Vande Hei was intended to come home on.

Whether Rubio truly does spend a year in space however remains uncertain. Two different Russian spacecraft — the Soyuz and a Progress freighter — have developed this coolant leak in the past three months. If this problem is a systemic manufacturing error, which Russia is now investigating, the decision might be to return the new capsule sooner than planned, out of fear it will develop its own leak. We shall likely find out sometime in the next three months.

If Rubio does end up in space for a full year, however, it will likely be a dream come true, having become an astronaut in 2017 but waiting six years for his first flight.

Leaking Soyuz capsule returns unmanned to Earth

9:06 am

The Soyuz capsule with a leaking coolant system successfully landed in Kazakhstan today, returning to Earth unmanned because of that leak.

Russian engineers will now analyze whether a crew would have been able to come home safely in that spacecraft, despite its damaged coolant system, which will provide information for future such problems. They will not be able to study the leak itself, however, as it was part of the capsule’s service module, which separates upon return and burns up in the atmosphere.

Russia considering bringing Soyuz launched on February 23rd home earlier

9:35 am

According to unnamed sources in the Russian press, Roscosmos officials are considering bringing the Soyuz capsule launched on February 23rd to ISS back to Earth in June rather than September, while moving up the launch of the next Soyuz manned mission.

As noted by space journalist Anatoly Zak:

The existence of such plans indicated that specialists had still been concerned about the possibility of a critical leak in the thermal control system of the fresh crew vehicle similar to those that hit two previous transport ships. Such change in schedule would also debunk the official explanation of previous two accidents by Roskosmos and NASA as caused by meteors rather than production defects.

The two previous coolant leaks occurred about three months after launch. Bringing the Soyuz home in June would get it home in about three and a half months, suggesting the Russians are no longer confident their Soyuz and Progress spacecraft can withstand six months in space.

If this plan is adopted it will also put less strain on the crew slated to come home on that Soyuz. Their mission has been planned for six months. Extending it to a full year without any prior preparation risks serious health issues.
