The video grab taken on Sept. 27, 2008 in Beijing, China, shows Chinese taikonaut Zhai Zhigang opening the door of the orbital module.

　　BEIJING, Sept 27 (Xinhua) -- A fire alarm the Shenzhou-7 spacecraft reported during China's maiden spacewalk Saturday afternoon was false, said Wang Zhaoyao, spokesperson with the manned space program late Saturday.

　　The alarm sounded because of a sensor error, said Wang at a press conference.

　　Taikonaut Zhai Zhigang floated out of Shenzhou-7 at about 4:34 p.m. (Beijing Time) Saturday, accomplishing China's first attempt on an extravehicular activity (EVA).
