Soyuz MS-28, Russian production No. 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.

Crew

The mission was 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 was scheduled to transport three Russian cosmonauts. However, NASA and Roscosmos were negotiating to extend their seat exchange program beyond 2025, ^[3] and in April 2025, NASA announced that Christopher Williams had been assigned to the crew. ^[4]
