A modified model of the Long March CZ-2F rocket carrying the unmanned spacecraft Shenzhou 8 blasts off from the launch pad at the Jiuquan Satellite Launch Center in northwest China's Gansu Province on Nov. 1. China's launch of the unmanned Shenzhou 8 spacecraft paves the way for a docking exercise with another craft. The docking, if successful, will lead to China's operation of a permanent space station around 2020, and make the nation the world's third to do so. China Daily/Reuters
