Soyuz MS-25, Russian production No. 756 and identified by NASA as Soyuz 71S, is an ongoing Russian crewed Soyuz spaceflight from Baikonur Cosmodrome to the International Space Station.[2][3]
Crew
[edit]This is the first launch of two women, Tracy Caldwell-Dyson from the United States and Maryna Vasileuskaya from Belarus,[4] aboard a Soyuz spacecraft. The mission commander is Russian cosmonaut Oleg Novitsky, born in Chervyen, Minsk Voblast, Byelorussian SSR, USSR (now Belarus).

Flight

It was originally scheduled for launch on 21 March 2024, but due to a voltage drop in one of the power generators, the launch was aborted.[5] The second launch attempt on 23 March 2024 was successful.
Caldwell-Dyson will spend approximately six months aboard the International Space Station. Roscosmos cosmonaut Oleg Novitsky and spaceflight participant Maryna Vasileuskaya of Belarus spent approximately 13 days aboard the orbital complex as a part of 21st ISS visiting expedition.[6]
Undocking and Return
[edit]At the end of Expedition 71, Caldwell-Dyson will return to Earth on 24 September 2024 with Roscosmos cosmonauts Oleg Kononenko and Nikolai Chub, who have been on the ISS since September 2023, on the Soyuz MS-25 spacecraft. They arrived with NASA astronaut Loral O'Hara on the Soyuz MS-24 spacecraft. O'Hara returned to Earth on MS-24 with Novitsky and Vasileuskaya.[6][7]
Kononenko and Chub will remain aboard the orbital laboratory for about one year. As the mission lasts 374 days, Kononenko will have spent a total of 1,111 days in space. He exceeded the previous record of 878 days held by Gennady Padalka on 4 February 2024. He later became the first person to stay 900 and 1,000 days in space on 25 February 2024 and 4 June 2024 respectively.
