The interior of Skylab B, on display at the Smithsonian's National Air and Space Museum The Genesis stations were "retired" when their avionics systems stopped working after two and a half years, yet they still remain in orbit thus become derelict spacecrafts NameĪs of 2022, two stations are orbiting Earth with life support system in place and fully operational. OPS 0855 was part of a cancelled Manned Orbiting Laboratory project by the United States, while the Genesis stations were launched privately. These stations and parts are prototypes they only exist as testing platforms and will never be crewed. programs are in orbit, but not necessarily operational. Note: Prototypes and various parts of Chinese, Japanese, and Russian, U.S. There have been numerous decommissioned space stations, including USSR's Salyuts, Russia's Mir, NASA's Skylab, and China's Tiangong 1 and Tiangong 2. In July 2022, Russia announced intentions to withdraw from the ISS after 2024 in order to build its own space station. China's Tiangong Space Station is scheduled to finish its phase 1 construction by the end of 2022 with the addition of two lab modules. The ISS is used to study the effects of spaceflight on the human body, as well as to provide a location to conduct a greater number and longer length of scientific studies than is possible on other space vehicles. ![]() The ISS has been permanently inhabited since October 2000 with the Expedition 1 crews and the TSS began continuous inhabitation with the Shenzhou 14 crews in June 2022. The ISS has hosted the highest number of people in orbit at the same time, reaching 13 for the first time during the eleven day docking of STS-127 in 2009.Īs of 2022, there are two fully operational space stations in low Earth orbit (LEO) – the International Space Station (ISS) and China's Tiangong Space Station (TSS). Uninterrupted occupation of stations has been achieved since the operational transition from the Mir to the ISS, with its first occupation in 2000. Stations have been occupied by consecutive crews since 1987 with the Salyut successor Mir. After the first station Salyut 1 (1971) and its tragic Soyuz 11 crew, space stations have been operated consecutively since Skylab (1973), having allowed a progression of long-duration direct human presence in space. Space stations have harboured so far the only long-duration direct human presence in space. Space stations have most often been launched for scientific purposes, but military launches have also occurred. The purpose of maintaining an orbital outpost varies depending on the program. Stations must have docking ports to allow other spacecraft to dock to transfer crew and supplies. An orbital station or an orbital space station is an artificial satellite (i.e. It lacks major propulsion or landing systems. A 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.
