Expedition 63 is the 63rd long duration mission to the International Space Station, scheduled to begin in April 2020 with the undocking of the Soyuz MS-15 spacecraft. The Expedition will consist of American commander Chris Cassidy, as well as Russian flight engineers Anatoli Ivanishin and Ivan Vagner.[1] The three crewmembers onboard Soyuz MS-17 will join the crew towards the end of the Expedition in October 2020[2].

Extra Vehicular Activity[edit]

Since delays to the US Commercial Crew Program might leave Cassidy as the only crew member on the USOS for an extended period of time, Anatoli Ivanishin has carried out training on US EMU spacesuits, in the unlikely event that an unscheduled EVA has to take place before any more USOS crew members arrive on the station, if Ivanishin takes place in an EVA in the EMU he will be the first Russian cosmonaut to use an EMU since Yuri Malenchenko (who performed the EVA with NASA Astronaut Peggy Whitson) during Expedition 16 in 2007[3]. For the same reason, Vagner has had to train on operating the USOS Robotic Arm (Canadarm 2) in order to robotically support any spacewalk carried out by Cassidy and Ivanishin.
