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]
