Soyuz MS-21 (No. 750, ISS mission 66S) is a Russian Soyuz spaceflight to the International Space Station with a crew of three planned for launch from Baikonur on 18 March 2022. The launch was previously planned for March 30, but in the provisional flight manifest prepared by Roskosmos by the end of Summer 2020, the launch of Soyuz MS-21 was advanced to March 18, 2022.[1]


As of Fall of 2020, the mission will mark the first flight of a US astronaut aboard Soyuz within the barter agreement between NASA and Roskosmos aimed to ensure presence of crew members from the two sides trained to operate the US and Russian segments of the station during long-duration expeditions. SpaceX Crew-3 may mark the first flight of a Russian cosmonaut on Crew Dragon under this barter agreement.[3] Roscosmos plans to name the official crew in early 2021.
