Soyuz MS-22

2022 Russian crewed spaceflight to the ISS

Soyuz MS-22 was a Russian Soyuz spaceflight to the International Space Station with a crew of three launched from Baikonur Cosmodrome on 21 September 2022. The launch, previously planned for 13 September 2022, was subsequently delayed to 21 September 2022 for a mission length of 188 days.[2]

Crew

The original three-Russian member crew was named in May 2021. American astronaut Francisco Rubio replaced Anna Kikina as a part of the Soyuz-Dragon crew swap system of keeping at least one NASA astronaut and one Roscosmos cosmonaut on each of the crew rotation missions. This allows continuous space station occupation by US and Russia and keep backup crew scenarios to prevent vehicle either vehicle grounding like Soyuz MS-10 launch failure or to compensate for delays in launch of crew rotation missions of either vehicles like SpaceX Crew-3, that was delayed due to unfavorable launch weather conditions.[3]

Spacecraft

The spacecraft is named in honor of Russian scientist Konstantin Tsiolkovsky, who is today considered one of the fathers of modern rocketry and astronautics. Tsiolkovsky's 165th birthday fell on 17 September, a few days before the launch of MS-22.[4]

Cooling loop accident

On 15 December 2022 at 12:45 UTC, a "visible stream of flakes" was observed emanating from the Soyuz spacecraft, concurrent with a loss of pressure in the external radiator cooling loop.[5] A scheduled spacewalk for Petelin and Prokopyev was cancelled while the incident was evaluated.[6]

The leak in the radiator occurred due to a micro-meteorite impact. The damage left a 0.8 mm diameter (0.031 in) hole into the external cooling radiator on the service module.[7]

Two working groups were formed to find the cause of the incident, analyze the technical condition of the ship and develop recommendations for further actions for ground specialists and the cosmonauts.[8]

According to tests conducted on the ship's systems, the temperature in the orbital and descent modules in the first days after the incident reached 30 °C (86 °F), and in the service module 40 °C (104 °F), but by January 2023, the temperature in the whole ship had stabilized at about 30 °C.

In December 2022, the outer surface of Soyuz MS-22 was examined using the cameras of the European Robotic Arm and Canadarm2.[9] The analysis of the data received on Earth allowed engineers to detect a possible place of damage on the surface of the service module.

In February 2023, days before undocking, Progress MS-21 encountered a similar problem with coolant pressure leak.[10]

Undocking and return

As Soyuz MS-22 was unable to perform crew return, it returned uncrewed (like Soyuz 32). MS-23 was launched uncrewed on 24 February 2023 to function as a replacement, bringing back the crew in September 2023 (similar to Soyuz 34). At that point, the crew spent a year in space. The original crew mission of MS-23 was delayed and reassigned to the MS-24 mission.[11][12] Thus, some dry cargo and equipment weighing 218 kg (481 lb) was brought back on the uncrewed return of Soyuz MS-22. Temperatures probably reached 50 °C (122 °F) on landing, more favourable than the worst emergency crewed landing scenario studied, as reported by the mission control team. More details were published later after analysis.[13]

Until the replacement MS-23 docked to ISS, SpaceX Crew-5 was considered among the options to return the MS-22 crew, in case of emergency. This is due to the fact that SpaceX originally designed the Crew Dragon to host a crew of seven. Accordingly, the International Space Station mission management team decided to move NASA astronaut Francisco Rubio's Soyuz seat liner from the Soyuz MS-22 spacecraft to Dragon Endurance in order to provide lifeboat capabilities for Rubio. The seat liner was moved on 17 January 2023, with installation and configuration continuing through most of the following day. Seat liner swapping is not new between two Soyuz capsules, but was performed for the first time from Soyuz to Crew Dragon.[14] The change allowed for increased crew protection by reducing the heat load inside the MS-22 spacecraft for cosmonauts Prokopyev and Petelin in the event of an emergency return to Earth. Alongside SpaceX Crew-6 space capsule is designed to bring back crew serving as a emergency evacuation after Crew-5.[15]

After MS-23 arrived at the station on 26 February, Rubio's seat liner was transferred to the new Soyuz on 6 March, and the seat liners for Sergey Prokopyev and Dmitry Petelin were moved from MS-22 to MS-23 on 2 March ahead of their return in the Soyuz.[14] MS-23 arrived and docked at the ISS on 26 February.[16]
