Shenzhou 7
Shenzhou 7 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 crewmembers Zhai Zhigang and Liu Boming, marked the commencement of the second phase of the Chinese government's Project 921.
The Shenzhou spacecraft carrying the three crewmembers was launched 25 September 2008, by a Long March 2F (CZ-2F) rocket 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.
The crew for Shenzhou 7 was announced on 17 September 2008
Crew:
Commander: Zhai Zhigang
Orbital module astronaut: Liu Boming
Descent module monitor astronaut: Jing Haipeng
Mission highlights
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°16′41〃N 111°21′18〃E / 42.278°N 111.355°E / 42.278; 111.355.
China has been congratulated by a number of foreign leaders for the successful completion of the mission, which marked a number of developments for China's space program, including several first-time achievements.
The Shenzhou 7 Mission won the 2009 Space Achievement Award from the Space Foundation
China's first three-person mission
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.
China's first spacewalk
On 27 September, Zhai Zhigang, wearing a Chinese-developed Feitian space suit, conducted a 22-minute space walk, the first ever for a Chinese astronaut. Zhai slipped out of the orbital module in a head-first position at around 16:43 (0843 GMT) and wandered around the orbital module, retrieved experiment samples and waved the Chinese flag in space. The spacewalk lasted about 20 minutes, with Zhai returning to the orbital module at 17:00. The first space walk was limited in scope: cables were used to tie Zhai to the handrail outside the orbital module, and his moving route was restricted to areas near the exits. Liu Boming, wearing a Russian Orlan-M suit, stayed in the airlock in the orbital module to provide help if necessary. Liu also conducted an EVA, standing up at 08:58 UTC to hand Zhai a flag. The third astronaut, Jing Haipeng remained in the re-entry module to monitor the general situation of the spacecraft. By 09:00 UTC both astronauts were back inside and the hatch was closed. The space walk was broadcast live on Chinese media, and two cameras provided panoramic images.
The Feitian spacesuit is similar to the Orlan-M in shape and volume and are designed for spacewalks of up to seven hours, providing oxygen and allowing for the excretion of bodily waste. According to Chinese media reports, spacesuit materials with such features as fire and radiation resistance were developed by several civilian corporations and national institutes. Each suit was reported to have cost 30 million RMB (about 4.4 million USD). Except for the gloves of the Feitian suit, the space suits were not brought back to earth.
A fire alarm was reported to the control center at the beginning of the EVA, but it was confirmed to be a false alarm.

Solid lubricant experiment
Scientists conducted a solid lubricant exposure experiment during the mission. A piece of equipment the size of a book was installed on the outside wall of the orbital module, and was later retrieved during the space walk, after having been exposed in the space for more than 40 hours. The experiment was aimed to study a lubricant which will be used for space-based moving components in future space facilities.

Release of miniaturized satellite
A miniaturized satellite was released during the mission on 27 September at 19:24, after Zhai returned to the spacecraft. The satellite was a cube about 40 cm (16 in) long, with a mass of 40 kilograms (88 lb); it carried boost devices and two 150-megapixel stereo cameras. The satellite's tasks included testing the mini-satellite technology, observing and monitoring the spacecraft, and testing the tracking and approaching technology used for space rendezvous and docking.
The miniaturized satellite took photos and videos near the spacecraft, then maneuvered to about 100 to 200 kilometres (62 to 120 mi) away from the spacecraft. After the return module separated from the spacecraft and re-entered the atmosphere, the satellite caught up to the orbiting spacecraft using a liquid ammonia engine, then continue to orbit around the spacecraft. The mini-satellite will work for about three months.

Data relay satellite
China launched its first-ever data relay satellite, called Tianlian I, from the Xichang Satellite Launch Center on a Long March-3C carrier rocket on 25 April 2008. The Tianlian I satellite will be used to speed up communication between the Shenzhou 7 spacecraft and the ground stations, and to increase the amount of data that can be transferred to the ground. The Tianlian I satellite alone can cover 50 percent of the orbit of Shenzhou 7—whereas the Yuanwang space tracking ships, along with China's ten ground observation stations, have a coverage of only 12 percent—and thus will increase the total coverage to about 60 percent of the mission.
