Soyuz MS-22
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.
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.
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.
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. A scheduled spacewalk for Petelin and Prokopyev was cancelled while the incident was evaluated.
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.
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.
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. The analysis of the data received on Earth allowed engineers to detect a possible place of damage on the surface of the service module.
