Expedition 64 was the 64th long-duration expedition to theInternational Space Station (ISS) that began on 21 October 2020 with the undocking and departure ofSoyuz MS-16. The expedition started with the three crew members who launched onboardSoyuz MS-17 and reached its full complement with the arrival ofSpaceX Crew-1, the first operational flight of NASA'sCommercial Crew Program (CCP).[5] As Crew-1 consisted of a crew of four instead of three like the Soyuz, this marked the beginning of operations for crews of seven on the ISS. In the final week of the mission,Soyuz MS-18 and its three person crew joined the mission. The expedition ended on 17 April 2021 with the departure ofSoyuz MS-17.[6]

Several spacewalks for Expedition 63 were planned to carry out work on the scientific and power systems on the ISS. Delays to the NASACommercial Crew Program leftChris Cassidy as the only crew member on theUS Orbital Segment (USOS) for an extended period of time. The arrival of theCrew Dragon Demo-2 mission permitted four EVAs by Cassidy andRobert Behnken to replace the remainingnickel-hydrogen batteries on theS6 Truss with newlithium-ion batteries.[7]
The planned work for activating theBartolomeo scientific package located on the outside of theColumbus laboratory module, delivered onSpaceX CRS-20, was postponed until Expedition 64.[8]
Ryzhikov and Kud-Sverchkov performed a spacewalk on 18 November 2020 to conduct initial preparations for the replacement of thePirs docking compartment by theNauka laboratory module, which lasted 6 hours and 48 minutes. This was the first EVA to be conducted from thePoisk airlock.[9] Coverage of the spacewalk, which NASA has designated "Russian Spacewalk #47", began at 14:30 UTC and lasted more than six hours.[10]
During late January through early March of 2021, NASA executed five spacewalks. The 27 January spacewalk, begun at 12:28 UTC and lasting 6 hours and 56 minutes, was conducted by Hopkins and Glover to install aKa band antenna onColumbus in preparation forBartolomeo's activation, replace a pin on theQuest Joint Airlock, and remove a grapple fixture on the P4 Truss for the beginning of a series of experimental solar array wing upgrades.[11][12]
The 1 February spacewalk, begun at 12:56 UTC and lasting 5 hours and 20 minutes, was conducted by Hopkins and Glover to conclude a four-year campaign, initiated byShane Kimbrough andPeggy Whitson onExpedition 50, to replace the batteries on the Integrated Truss Structure.[13][14] Hopkins and Glover also installed and upgraded several cameras on the starboard truss, theDestiny laboratory, and theKibo robotic arm.[15][16][11]
The 28 February spacewalk, begun at 11:12 UTC and lasting 7 hours and 4 minutes, was conducted by Rubins and Glover to install on the P6 Truss brackets for the experimental solar array upgrades, the main materials for which launched in June 2021 aboardSpaceX CRS-22.[17]
The 5 March spacewalk, begun at 11:37 UTC and lasting 6 hours and 56 minutes, was conducted by Rubins and Noguchi to continue the bracket installation work.[1][2][3][4] They had also initially planned to deploy a new airlock cover to strengthenQuest, replace a wireless video transceiver on theUnity node, route more cables onBartolomeo, and vent and rearrange ammonia hoses. Rubins and Noguchi abandoned the planned additional work because they encountered difficulties with several bolts during the bracket installation.[17][18][19]
The 13 March spacewalk, begun at 13:14 UTC and lasting 6 hours and 47 minutes, was conducted by Hopkins and Glover to finish the work not taken up by Rubins and Noguchi, although they deferred installing clamps onBartolomeo to a future spacewalk.[20]
