List of visiting expeditions to the International Space Station

The permanent occupation of the station is carried out by core crews, who usually stay for six months.

Three-seat, single-use Soyuz serve as lifeboats on the ISS, changing every six months.

In the period 2000–2002, when crews were switched to the space shuttle, visiting expeditions ended up being three people.

The next short visit did not occur until September 2015, in connection with the one-year mission to the ISS, and then in 2019.

Continued international collaboration on ISS missions has been thrown into doubt by the 2022 Russian invasion of Ukraine and related sanctions on Russia.
