JIUQUAN, Sept. 9 (Xinhua) -- China's second space lab Tiangong-2 is scheduled to be put into space between September 15 and 20, according to the office of China's manned space program.

The space lab was transferred with its carrier rocket to the launch pad at Jiuquan Satellite Launch Center in northwest China on Friday, said a statement from the office.

Technicians completed testing on the assembling of the lab and the rocket after they had been separately delivered to the launch center in July.

In the next few days, the launch center will continue testing rocket and inject propellent before the launch.

Tiangong-2, which can enable two astronauts to live in space for 30 days, is capable of receiving manned and cargo spaceships and will be used for testing systems and processes for mid-term space stays and refueling.

It will also be involved in experiments on aerospace medicine, space sciences, on-orbit maintenance and space station technologies.
