China has an ambitious space programme with the country's rulers using it to garner support from the population and boost international prestige.
Since launching its first manned mission in 2003, China has sent up an experimental space station, Tiangong-1, staged a space walk and landed its Yutu rover on the moon.
Its second space station, Tiangong-2, was sent into orbit from al aunch facility in the Gobi desert in September, according to statemedia.Tiangong-2 is intended as a precursor to the building of a full-size manned space station.
A Shenzhou 11 spaceship with two astronauts is scheduled to dock with the station on October 17.
Officials have previously suggested a manned landing on the moon could also be part of China's space programme in the future.
