Chinese astronaut makes nation's first spacewalk

A Chinese astronaut on Saturday performed the nation's first-ever spacewalk, the latest milestone in an ambitious program that is increasingly rivaling the United States and Russia in its rapid expansion. Mission commander Zhai Zhigang floated out of the orbiter module's hatch in the spacewalk, shown live on state broadcaster CCTV. Tethered to handles attached to the Shenzhou 7 ship's orbital module's exterior, Zhai remained outside for about 13 minutes before climbing back inside and closing the hatch behind him. "Shenzhou 7 has left the module, physically feel very good. Greetings to all the people of the nation and all the people of the world," Zhai said.
