China plans space station with module launch

China will launch a space module next year and carry out the nation’s first space docking in 2011 as a step towards its goal of building a space station, state media said on Sunday.

The Tiangong-1, or “Heavenly Palace-1”, is scheduled for launch in late 2010 and will dock with a Shenzhou-8 spacecraft early the following year, Xinhua news agency said, citing officials with China’s space program.

“The module, named Tiangong-1, is designed to provide a ’safe room’ for Chinese astronauts to live and conduct scientific research in zero gravity,” the report said.

“Weighing about 8.5 tonnes, Tiangong-1 is able to perform long-term unattended operation, which will be an essential step toward building a space station.”

Space program officials have previously said China is expected to place in orbit several modules like the Tiangong and link them up to form a semi-permanent space platform.

It was not immediately clear if the Tiangong-1 would eventually serve as China’s first manned space station, or whether it would only be a platform to test docking and space station technology.

The planned 2011 space docking would be remotely carried out by scientists on the ground and would not involve astronauts, the report said.

China became the third nation to put a man in space when Yang Liwei piloted the one-man Shenzhou-5 space mission in 2003.

Last September, the Shenzhou-7, piloted by three “taikonauts” or astronauts, carried out China’s first space walk.

Several prototypes of the Tiangong would be built this year, while upgrades to the carrier rocket that will launch the module into space would also be carried out, the report said.

Following the Shenzhou-8 flight, China also hopes to begin the mass production of Shenzhou spacecraft which will be used to transport astronauts to the space station, it said.

The International Space Station commenced with the launch into orbit of the first station element, a Russian-built module on November 20, 1998.

It orbits some 350 kilometres above the earth’s surface with a permanent crew of three astronauts who remain aboard for stays lasting several months.
