中国发射“天宫一号”，瞄准空间站

China has launched an unmanned spacecraft, in what is described as Beijing's first step toward building its own space station.The 8.5 ton module -- known as Tiangong-1, or "Heavenly Palace" -- lifted off from a site in China's northwestern Gobi desert late Thursday night local time. The craft was propelled by a Long March 2F rocket. Detailed reports about the launch were splashed across Chinese newspapers and the development was hailed by state-run broadcasters.
 
Another unmanned spacecraft to be launched November 1 will meet up with the module for China's first space-docking procedure.China plans several more rendezvous-and-docking procedures before the end of next year -- at least one of which will be manned. The program calls for construction of a space laboratory by 2016 and completion of a 60-ton space station around 2020.China conducted its first manned space flight in 2003, more than four decades after pioneering flights by the United States and Soviet Union. The latest efforts come at a time when the retirement of the U.S. space shuttle fleet has left the future of the American space program in question.
