     Jiuquan, Gansu Sept. 25 (Xinhua)-China launched its third manned spacecraft on Thursday with three

astronauts on board to attempt the country's first-ever space walk.

     The spaceship Shenzhou-7 blasted off on a Long March II-F carrier rocket from the JiuQuan Satellite

Launch Center in the northwestern Gansu Province at 9:10 pm. after a breathtaking countdown to another

milestone on China's space journey. Onboard pilots Zhai Zhigang, Liu Boming and Jing Haipeng are expected

to orbit the earth for three days, when one of them will float out of the cabin about 343 kilometers above the

earth. 　　

     When they make it, China will become the third country in the world who is able to conduct

extra-vehicular activity (EVA) in space following the former Soviet Union and the United States. 　　

     President Hu Jintao watched the historic moment at the launch center, joined by Chinese experts and other

work staff. 　　

     Two taikonauts would enter the orbital module, where one would put on domestically-made spacesuit

Feitian and leave the module to take back test samples loaded outside, said Zhou Jianping, chief designer of

the country's manned space project.

     The other would wear a Russian Orlan suit and stay in the depressurized cabin for support, said Zhou.

"We wish we could fly freely in space just like Feitian on the ancient Buddhist murals, so we gave this name

to the homemade spacesuit," said Zhou. Feitian, which literally means flying in the sky, is the name of a

legendary Buddhist goddess.

     Other tasks of the Shenzhou-7 crew include the release of a small monitoring satellite and a trial of the

data relay of the satellite Tianlian-I. 　　

     The taikonauts, all 42 years old, are scheduled to land in the central region of north China's Inner Mongolia

Autonomous Region in a re-entry module after their mission is completed.
