List of visitors to the International Space Station

Initially all private space travel was aboard the Russian Soyuz spacecraft.

Private travelers would remain on the ISS during handover from one expedition crew to the next, generally a week or two.

The NASA Space Shuttle carried seven crew members, and the longest docking with the ISS was 11 days.

Many visitors to the ISS were accommodated for short periods during NASA shuttle dockings.

NASA stated it was "not interested" in private spaceflight during construction of the ISS, but eventually began allowing up to two flights per year in 2019, with the first private visitors arriving at the US Orbital Segment in 2022 on a SpaceX Crew Dragon.
