Expedition 71
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 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
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 Starliner Crewed Flight Test.[4] Boeing Starliner Crewed Flight Test (consisting of NASA astronauts, Barry Wilmore and Sunita Williams) docked during the expedition on 6 June 2024.[7][8]

| Besides the expedition crew, Boeing CST-100 Starliner is visiting the station for a crewed flight test, consisting of NASA astronauts Barry Wilmore and Sunita Williams.[8] Boeing spacecraft 3, later named Calypso, named after Jacques-Yves Cousteau's oceanography vessel, RV Calypso,[12] launched and docked to the station in June 2024. The flight marked the first crewed test flight of Boeing's CST-100 Starliner spacecraft. Crew members are staying aboard the station for approximately 6 days. It was the first launch of humans from Cape Canaveral Space Force Station since Apollo 7 in October 1968, and first launch of humans from SLC-41.[8] | ||||

Notes
- 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]
