[4][5] 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] NASA astronauts Barry Wilmore and Sunita Williams arrived at the station on 6 June 2024 as part of the Boeing Crew Flight Test.

[4][7][8] However, due to technical issues with their spacecraft, their stay was extended, and they became de facto members of the ISS crew.

NASA also announced that Wilmore and Williams would formally be added to the Expedition 71/72/73 crew.
