Premier Wen Jiabao welcomed Chinese astronauts home from Beijing, saying the mission's success was a milestone as China has become the third country to independently conduct a spacewalk.
Chinese astronaut Zhai Zhigang slipped out of the orbital module of ShenzhouVII Saturday afternoon, starting China's first spacewalk or extravehicular activity (EVA) in the outer space.
