China is due to launch its first space laboratory, Tiangong-1.

中国将发射首颗太空实验室,天宫1号。

China is taking a stepped approach to the development of its human spaceflight programme
The 10.5m-long, cylindrical1(圆柱形的) module2 will be unmanned for the time being, but the country's astronauts, or yuhangyuans, are expected to visit it next year.

Tiangong-1 will demonstrate the critical technologies needed by China to build a fully3 fledged space station - something it has promised to do at the end of the decade.

The space lab is set to ride to orbit atop a Long March 2F rocket.

State media say the lift-off from the Jiuquan Satellite Launch Centre in Gansu Province is likely to occur between 21:16 and 21:31 local time (13:16-13:31 GMT).

The Long March will put Tiangong in a near-circular path around the Earth, just a few hundred km above the surface.

It will operate in an autonomous4(自主的) mode, monitored from the ground. Then, in a few weeks' time, China will launch another unmanned spacecraft, Shenzhou 8, and try to link the pair together.

This rendezvous5(集合点) and docking capability6 is a prerequisite7(先决条件) if larger structures are ever to be assembled in orbit.

Commentators8 say Russian technology, or a close copy of it, will be used to bring the two craft into line.

Assuming the venture goes well, two manned missions (Shenzhou 9 and 10) should follow in 2012. The yuhangyuans - two or three at a time - are expected to live aboard the conjoined(联合的) vehicles for up to two weeks.
