Chinanews, Shanghai, Nov. 21 – The "Shenzhou 7" might carry three astronauts aboard and it will possibly be launched in October next year. By then, astronauts will conduct a space walk, probably with a belt, said Pang Zhihao, a research fellow at the China Academy of Space Technology, the Oriental Morning Post reported.“The launch can be described in two words ‘thrilling’ and ‘exciting’. Chinese public can see every detail of the launching process with televised live broadcast,” Pang said.“This will be the first time for Chinese astronauts to conduct a space walk. So it will be a very exciting event,” he said.Normally, astronauts can conduct a space walk with or without a belt. If they tie a belt, the trip will be safer for them and they can get more oxygen and communicate with researchers on earth with the belt, Pang noted.“As this will be the first time for Chinese astronauts to conduct a space walk, they will probably tie a belt in carrying out the mission,” Pang added.
