The International Space Station is a modular space station in low Earth orbit. It is a multinational collaborative project involving five participating space agencies: NASA, Roscosmos, JAXA, ESA, and CSA. The ownership and use of the space station is established by intergovernmental treaties and agreements.
In February, the Crew-1 astronauts passed the record for the most days in space by a crew launched on a U.S. spacecraft, surpassing the milestone of 84 days that was set by the Skylab 4 crew in 1974. Since then, they have doubled that record, staying onboard the International Space Station for 168 days

A space station, also known as an orbital station or an orbital space station, is a spacecraft capable of supporting a human crew in orbit for an extended period of time, and is therefore a type of space habitat. It lacks major propulsion or landing systems. Stations must have docking ports to allow other spacecraft to dock to transfer crew and supplies.

Since 1971, 12 space stations launched into a low orbit around Earth have been occupied for varying lengths of time. In chronological order they are Salyut 1, Skylab, Salyuts 3, 4, 5, 6, and 7, Mir, the International Space Station, Tiangongs 1 and 2, and a larger Chinese space station simply called Tiangong
