Since the Soviet Union launched the first space station, Salyut 1, 50 years ago, humans have lived on a total of 11 such facilities in Earth orbit. China will soon add one more to that list. With the core module of the Chinese Space Station (CSS) scheduled to lift off at the end of April, the cumulation of a project the nation’s government initially envisioned in 1992 is finally entering the construction phase.

After the core module reaches space, China plans at least 10 more launches of other major modules, as well as crewed and cargo missions, to complete the station’s assembly by the end of 2022. At that time the CSS will join the International Space Station (ISS) as the only fully operational space stations in orbit.
