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.[1]
Uncrewed missions are designated as Kosmos instead of Soyuz; exceptions are noted "(uncrewed)". The † sign designates failed missions. Italics designates cancelled missions.
