Russia is set to launch three people to the International Space Station in Soyuz MS-25 from Baikonur Cosmodrome in Kazakhstan.

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.

Because of an abort during the initial launch attempt, Soyuz MS-25 will take two days to reach the ISS instead of the typical three hours.
