Crew

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.
