SpaceX has a new partner for commercial private astronaut flights aboard its Dragon spacecraft: Space Adventures, a private space tourism company that has already launched private astronauts including Anousheh Ansari, Guy Laliberté and Mark Shuttleworth to space.

Space Adventures has worked with seven clients across high serrate missions to the International Space Station (ISS) for private paying commercial space missions, using paid seats on the Russian Soyuz rocket to get its clients to their destination. Its experience means it’s uniquely positioned in the commercial space tourism industry to actually make this happen, which means SpaceX likely will start flying paying customers as soon as its able to human-rate its Dragon spacecraft and begin scheduling flights.
