Soyuz MS-17 was Soyuz spaceflight that was launched on 14 October 2020. It transported three crew members of the Expedition 63/64 crew to the International Space Station. Soyuz MS-17 was the 145th crewed flight of a Soyuz spacecraft. The crew consisted of a Russian commander Roscosmos cosmonaut Sergey Ryzhikov a Russian flight engineer Roscosmos cosmonaut Segey Kud-Sverchkov and American NASA astronaut Kathleen Rubins. The mission marked the first use of a new "ultrafast" two-orbit rendezvous flight plan with the Soyuz, which saw Soyuz MS-17 arrive at the ISS within approximately three hours after the launch. On 19 March 2021, the crew of Soyuz MS-17 boarded their spacecraft to relocate it from Rassvet to Poisk to make way for the arrival and docking of the Soyuz MS-18 spacecraft.    The two spacecrafts had a nine-day handover period before Soyuz MS-17 departed. This is necessary to avoid de-crewing the Russian Orbital Segment of the ISS since no Russian cosmonaut was present aboard SpaceX Crew-1.
