Shenzhou 7

Shenzhou 7 (simplified Chinese: 神舟七号; traditional Chinese: 神舟七號; pinyin: Shénzhōu Qī Hào) was the third human spaceflight mission of the Chinese space program. The mission, which included the first Chinese extra-vehicular activity (EVA) carried out by crew members Zhai Zhigang and Liu Boming, marked the start of the "second step" of the China Manned Space Program.

The Shenzhou spacecraft carrying the three crew members was launched 25 September 2008, by a Long March 2F rocket, making its final flight before being replaced by the 2F/G, which lifted off from the Jiuquan Satellite Launch Center at 21:10 CST. The mission lasted three days, after which the craft landed safely in Siziwang Banner in central Inner Mongolia on 28 September 2008, at 17:37 CST. The Shenzhou 7 EVA made the Chinese space program the third to have conducted an EVA. EVAs had previously been conducted by the space programs of the Soviet Union (later Russia) and the United States.

Crew

The crew for Shenzhou 7 was announced on 17 September 2008.

Of the back-up crew, only Chen Quan had not previously flown in space.

Mission highlights

Shenzhou 7 was the first Chinese space mission to carry a three-person crew for several days and conduct a full operation. A total of six astronauts were trained, three to conduct the mission and three others to serve as a backup crew.

The Long March 2F rocket launched the Shenzhou 7 into an initial elliptical orbit of 200 x 330 kilometres inclined at 42.4 degrees on 25 September 2008. About seven hours later the spacecraft raised its orbit to a more circular orbit of 330 x 336 km. After three days in space, deorbit manoeuvres began on 28 September at 08:48, and the return module landed at 09:37 UTC at coordinates 42.278°N 111.355°E / 42.278; 111.355.
