Expedition 64 is the 64th and current long-duration expedition to the International Space Station (ISS), that began on 21 October 2020 with the undocking and departure of Soyuz MS-16. The Expedition started with the three crew members launched onboard Soyuz MS-17 and reached its full complement with the arrival of SpaceX Crew-1, the first operational flight of NASA's Commercial Crew Program (CCP).[2] As Crew-1 consists of a crew of four instead of three like the Soyuz, Expedition 64 marks the beginning of operations for crews of seven on the ISS. In the final weeks of the mission, Soyuz MS-18 and its three cosmonaut crew are scheduled to join the mission. The expedition is scheduled to end on 18 April 2021 with the departure of Soyuz MS-17.[3]

Extravehicular activity
Several spacewalks for Expedition 63 were planned to carry out work on the scientific and power systems on the ISS. Delays to the NASA Commercial Crew Program left Chris Cassidy as the only crew member on the US Orbital Segment (USOS) for an extended period of time. The arrival of the Crew Dragon Demo-2 mission permitted four EVAs by Cassidy and Robert Behnken to replace the remaining nickel-hydrogen batteries on the S6 Truss with new lithium-ion batteries.[4]
The planned work for activating the Bartolomeo scientific package located on the outside of the Columbus laboratory module, delivered on SpaceX CRS-20, was postponed until Expedition 64.[5]
Ryzhikov and Kud-Sverchkov performed a spacewalk on 18 November 2020 to conduct initial preparations for the replacement of the Pirs docking compartment by the Nauka laboratory module, which lasted 6 hours and 48 minutes. This was the first EVA to be conducted from the Poisk airlock.[6] Coverage of the spacewalk, which NASA has designated "Russian Spacewalk #47", began at 14:30 UTC and lasted more than six hours.[7]
