BEIJING, Sept. 25 (Xinhua) -- Chinese scientists on Sunday maneuvered the country's Tiangong-2 space lab to a preset orbit 393 kilometers above Earth's surface, in preparation for a planned docking with the Shenzhou-11 manned spacecraft set to launch next month.

Tiangong-2, which blasted off from the Jiuquan Satellite Launch Center on the back of a Long March-2F T2 rocket on Sept. 15, has already gone through about nine days of on-orbit testing before Sunday's maneuver, according to the Beijing Aerospace Control Center.

Earlier reports said China's future space station, which the country plans to put into service around 2022, will also be orbiting the Earth at approximately the same height - 393 kilometers above ground.

The Shenzhou-11 manned spacecraft is expected to carry two astronauts into space to dock with the Tiangong-2 in October. The astronauts will work in the lab for 30 days before returning to Earth.
