On 14 May, the Interagency Committee approved the composition of the ISS main and alternate crews for the period 2021–2023. Cosmonaut Anton Shkaplerov was chosen to be the ship's commander, while Klim Shipenko and Peresild flew as spaceflight participants. The backup crew was cosmonaut Oleg Artemyev, cameraman Alexei Dudin and actress Alyona Mordovina, Mordovina being the first woman to pass the cosmonaut screening since 2012. Due to the allocation of seats on flights to the International Space Station, the flight of the director and actress necessitated rearranging mission lengths of the professional astronauts and cosmonauts, including extending the mission length of the on-orbit crew, U.S. astronaut Mark Vande Hei and his Russian cosmonaut counterparts, from six months to 1 year.
