Expedition 71 is the 71st long-duration expedition to the International Space Station. The expedition began with the departure of Soyuz MS-24 on 6 April 2024[1] with Russian cosmonaut Oleg Kononenko continuing his ISS command from Expedition 70.[2][3] It will end with his departure on Soyuz MS-25 with crewmates from MS-24 and MS-25 on 24 September 2024.[4][5]
Background, crew and events
[edit]Initially, the expedition consisted of Kononenko, his Russian Soyuz MS-24 crewmate Nikolai Chub (both on a year long ISS mission since 15 September 2023), and his American Soyuz MS-25 crewmate, Tracy Caldwell-Dyson, who launched on 23 March 2024, as well as SpaceX Crew-8 crewmates, American astronauts Matthew Dominick, Michael Barratt, and Jeanette Epps, and Russian cosmonaut Alexander Grebenkin, who launched on 4 March 2024 and were transferred from Expedition 70 after Soyuz MS-24 departure.[5][3][6]
The crew will later be replenished by subsequent crew rotation missions in the expedition, i.e., Boeing Crew Flight Test[4] (consisting of NASA astronauts Barry Wilmore and Sunita Williams), which docked during the expedition on 6 June 2024.[7][8]

Besides the expedition crew, a Boeing Starliner spacecraft is visiting the station for a crewed flight test, consisting of NASA astronauts Barry Wilmore and Sunita Williams.[8] The spacecraft Calypso,[12] launched and docked to the station in June 2024. The flight marked the first crewed test flight of the Starliner. Crew members were scheduled to stay aboard the station for approximately 6 days, but the mission was extended due to issues with the spacecraft. It was the first launch of humans from Cape Canaveral since Apollo 7 in October 1968, and first launch of humans from SLC-41.[8] |

Notes
[edit]- ^ a b Counting the aborted flight of Soyuz MS-10, even though this did not quite cross the Kármán line. This matches NASA's count, though RSA follows the Kármán line definition.[11]
