NASA must approve all private astronaut missions (PAMs) to the ISS Highlights SpaceX to launch two private astronaut missions to ISS Vast Space partners with SpaceX for ISS missions NASA approval pending for Vast Space astronaut flights Advertisement SpaceX has entered into an agreement with Vast Space to conduct two private astronaut missions to the International Space Station (ISS). The California-based Vast Space is reportedly working on its own private space station, Haven-1, which could be operational as early as next year. Both missions will utilise SpaceX's Falcon 9 rocket and Crew Dragon capsule, pending approval from NASA. The flights align with Vast Space's broader strategy to support payload and crewed missions to the ISS, according to a statement attributed to Max Haot, CEO of Vast Space. Haot noted that this approach facilitates collaboration with NASA and other international space agencies. The company has ambitions to advance human spaceflight capabilities through projects like Haven-2, an upgraded space station design expected to launch its first module by 2028. NASA's Role in Approving Private Astronaut Missions The official blog have highlighted that NASA must approve all private astronaut missions (PAMs) to the ISS. Thus far, four such missions have been sanctioned, all proposed by Axiom Space and conducted with SpaceX as the transportation provider. Vast Space's plans for two new missions will need to pass similar scrutiny.
