China plans to launch an unmanned space module, Tiangong-1, in 2011, which is expected to accomplish the country’s first space docking and regarded as an essential step toward building a space station, an expert said Wednesday.

Tiangong, or the Heavenly Palace, would finally be transformed into a manned space lab after experimental dockings with three Shenzhou spacecraft, which are expected to be put into space within two years following the module’s launch, said Qi Faren, former chief designer of Shenzhou spaceships.
