Expedition 71 was the 71st long-duration expedition to the International Space Station. The expedition began with the departure of Soyuz MS-24 on 6 April 2024 with Russian cosmonaut Oleg Kononenko continuing his ISS command from Expedition 70. It ended with his departure on Soyuz MS-25 with crewmates from MS-24 and MS-25 on 23 September 2024.
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.
NASA astronauts Barry Wilmore and Sunita Williams arrived at the station on 6 June 2024 as part of the Boeing Crew Flight Test. Their visit was planned to be brief. However, due to technical issues with their spacecraft, their stay was extended, and they became de facto members of the ISS crew. They assisted with various tasks, including research, housekeeping, and maintenance. On 24 August 2024, NASA announced that the Boeing Starliner spacecraft would return to Earth uncrewed, with Wilmore and Williams being formally added to the Expedition 71/72 crew and returning aboard SpaceX Crew-9 on 18 March 2025.
On 11 September 2024, Soyuz MS-26 arrived at the station, transporting Roscosmos cosmonauts Aleksey Ovchinin and Ivan Vagner, as well as NASA astronaut Donald Pettit.
