Soyuz MS-25 was a Russian crewed Soyuz mission to the International Space Station. After an earlier launch attempt was scrubbed, the spacecraft launched on March 23, 2024 UTC with NASA astronaut Tracy Caldwell Dyson, Roscosmos cosmonaut Oleg Novitsky, and Belarusian spaceflight participant Maryna Vasileuskaya. It docked to the station's Prichal module on March 25, bringing Dyson into the resident Expedition 70 and 71 crew while Novitsky and Vasileuskaya began a short visiting mission. Novitsky and Vasileuskaya spent about 12 days aboard the station and returned on Soyuz MS-24 with NASA astronaut Loral O'Hara on April 6, 2024. Soyuz MS-25 remained attached as a return spacecraft for Dyson and for Roscosmos cosmonauts Oleg Kononenko and Nikolai Chub, whose yearlong mission had begun on Soyuz MS-24. The spacecraft landed in Kazakhstan on September 23, 2024, returning Dyson after a 184-day mission and returning Kononenko and Chub after 374 days in orbit.
