Soyuz MS-28

759 and identified by NASA as Soyuz 74S, is a planned Russian crewed Soyuz spaceflight to launch from Site 31/6 at the Baikonur Cosmodrome no earlier than 27 November 2025 to the International Space Station.

The mission is slated to be the first to launch after the termination of a NASA/Roscosmos barter agreement, where one Russian cosmonaut flies on a NASA spacecraft in exchange for one NASA astronaut flying on a Soyuz.

Consequently, as of 2024[update], this mission is currently scheduled to transport three Russian cosmonauts.

However, NASA and Roscosmos are negotiating to extend their seat exchange program beyond 2025.
