Expedition 70

Expedition 70 was an International Space Station increment that began on September 27, 2023, after Soyuz MS-23 undocked and Expedition 69 concluded. NASA's Expedition 70 page presents the seven core portrait crew: Andreas Mogensen, Jasmin Moghbeli, Satoshi Furukawa, Loral O'Hara, Konstantin Borisov, Oleg Kononenko, and Nikolai Chub. Spacefacts records the fuller resident-increment roster as those seven plus the arriving Crew-8 astronauts Matthew Dominick, Michael Barratt, Jeanette Epps, and Aleksandr Grebyonkin, and Soyuz MS-25 flight engineer Tracy Caldwell Dyson. Mogensen commanded the station at the start of the increment and handed command to Kononenko in March 2024. Expedition 70 included two EVAs: Kononenko and Chub completed a Russian-segment spacewalk on October 25, 2023, and Moghbeli and O'Hara completed a U.S. segment spacewalk on November 1, 2023. The increment also handled Crew-7 departure, Crew-8 arrival, Soyuz MS-25 arrival, cargo vehicle operations, station maintenance, and research in fields including human health, space manufacturing, and biological science. Expedition 70 concluded with the Soyuz MS-24 undocking on April 6, 2024 UTC, transitioning the station to Expedition 71.
