Russian crewmembers of the 65th long-term expedition to the International Space Station work in accordance with the flight task. Today, October 7, 2021, in preparation for the upcoming landing, the Soyuz MS-19 spacecraft crew is swapping the Soyuz MS-19 and Soyuz MS-18 seat liners. Return to Earth is scheduled for October 17, 2021.
The crew also continues to work on filming the scientific and educational project ‘Challenge’. The health condition of the cosmonauts and spaceflight participants is good.
The seat liners act as shock absorbers evenly distributing the loads to protect the crew during the landing. Each seat liner is made individually for each cosmonaut as part Kazbek-UM chair shock-absorbing chair of Soyuz MS spacecraft, where the cosmonaut (or spaceflight participant) stays during the flight.
Three times in the history of Russian cosmonautics the seat liners saved the lives of the crews returning from Earth orbit in 1969 (Boris Volynov), in 1980 (Valery Kubasov and Bertalan Farkash), in 1997 (Vasily Tsibliev, Alexander Lazutkin). The impact on the ground was so strong that the astronauts survived largely thanks to the seat liners.
The spaceflight participants Yulia Peresild and Klim Shipenko, who flew to the International Space Station as part of the scientific and educational project ‘Challenge’ will return to Earth on October 17 on the Soyuz MS-18 spacecraft together with Roscosmos cosmonaut Oleg Novitskiy, who has been at the ISS since April. Shkaplerov and Dubrov will spend another 174 days at the station.
According to preliminary data from the TsNIImash Mission Control Center (part of Roscosmos), the Soyuz MS-18 spacecraft is scheduled to undock at 01:12 UTC on October 17, 2021. The descent capsule is expected to land at 04:36 UTC of the same day, 147 km from the city of Zhezkazgan.
