Two days after launch, Russia’s Soyuz MS-25 spacecraft and its three occupants are set to dock with the International Space Station.

Flying aboard is Roscosmos cosmonaut Oleg Novitsky, Belarusian spaceflight participant Marina Vasilevskaya and NASA astronaut Tracy Caldwell-Dyson.

Caldwell-Dyson will remain aboard the ISS for six months. However, Novitsky and Vasilevskaya will return to Earth in early April in Soyuz MS-24 with NASA astronaut Loral O’Hara, who has been aboard the ISS since launching into space September 2023.

The other two members of Soyuz MS-24, Russian cosmonauts Oleg Kononenko and Nikolai Chub, are slated to remain aboard ISS until September 2024 and will return in Soyuz MS-25 with Caldwell-Dyson.

Soyuz MS-25 is expected to dock with the Earth-facing port of the Prichal module roughly two days after launch.
