Soyuz MS-25 is a planned Russian crewed Soyuz spaceflight to launch from Baikonur in March 2024 to the International Space Station.[1][2]

Crew

American astronaut Tracy Caldwell-Dyson replaced Alexander Grebenkin as a part of the Soyuz-Dragon crew swap system of having at least American and Russian crew member on ISS. This allows continuous space station occupation by US and Russia and keep backup crew scenarios to prevent vehicle either vehicle grounding like Soyuz MS-10 launch failure or to compensate for delays in launch of crew rotation missions of either vehicles like SpaceX Crew-3, that was delayed due to unfavorable lauch weather conditions.[3]

Flight

Dyson will launch on the Soyuz MS-25 spacecraft and spend approximately six months aboard the International Space Station. She will travel to the station with Roscosmos cosmonaut Oleg Novitsky and spaceflight participant Marina Vasilevskaya of Belarus, both of whom will spend approximately 12 days aboard the orbital complex as a part of 21st ISS visiting expedition.[5]

Undocking and Return

After completing her expedition, Dyson will return to Earth in fall 2024 with Roscosmos cosmonauts Oleg Kononenko and Nikolai Chub on the Soyuz MS-25 spacecraft. Kononenko and Chub are there on ISS since September 2023, with NASA astronaut Loral O’Hara on the Soyuz MS-24 spacecraft. Kononenko and Chub will remain aboard the orbital laboratory for about one year. If the mission lasts 300-365 days, Kononenko will have spent a total of 1,036-1,101 days in space, exceeding the current record of 878 days by Gennady Padalka. He will thus also become the first person to stay 1,000 days in space. O’Hara, who will spend six months aboard the space station, will return with Novitsky and Vasilevskaya on the Soyuz MS-24 spacecraft.[5][6]
