Space station

A space station is a artificial satellite in space that people can live at. All past and current space stations have been in low Earth orbit. Space stations can dock with other spacecraft. This allows transferring cargo and people. At present the International Space Station is the only space station in orbit. The first space station was Salyut 1. Prior stations were the seven Salyut stations, Skylab, Mir and the two Tiangong stations. The Chinese Space Station is planned for the future.

International Space Station

Space stations are used to learn about how being in space for a long time affects the human body. They also are a place for science experiments and research. Space stations have been designed for more than one crew. Each crew member may stay aboard the station for weeks or months, and then is replaced by others. Some have spent more than one year at a time on a space station. This includes Vladimir Titov, Musa Manarov, Sergei Avdeyev and Valeriy Polyakov aboard Mir.

List of successful stations

The below list is of stations that made it to orbit and had at least one crew visit them. There have also been a few stations that have failed or were for testing. Those are not included on this list.

Research and development of parts for space stations

Prototype of LIFE habitat inside the Space Station Processing Facility (2021)

In 2024, international media showed a film clip of (intentionally or on purpose) putting too much pressure inside a LIFE (Large Integrated Flexible Environment) habitat [or a room designed for a future space station].
