1999165438+1At 6: 30 on October 20th, Shenzhou-1 spacecraft was successfully launched from Jiuquan Satellite Launch Base and returned to the ground after a flight of 2 1 hour.

Little known is that the "pioneer officer" of this manned spaceflight project was actually temporarily modified from the electrical performance test spacecraft used for ground tests. It is unprecedented in China's space history to directly use original products as normal products.

Shenzhou II

In the early morning of 200110, the Shenzhou II spacecraft was successfully launched. The spacecraft returned to the ground after running in orbit for nearly 7 days.

Shenzhou II is the first full-scale unmanned spacecraft, and its technical status is basically the same as that of manned spacecraft. Its launch is completely carried out according to the environment and conditions of manned spacecraft, and all the equipment related to astronauts' life support are basically genuine.

Shenzhou III

On March 25th, 2002, Shenzhou III was launched and returned to the ground at 4 1.

Shenzhou III spacecraft is equipped with human metabolism simulator, anthropomorphic physiological signal equipment and human dummy, which can quantitatively simulate astronauts' breathing, blood circulation and other important physiological activity parameters. The spacecraft worked normally, all the scheduled test targets were achieved, and the test was a complete success.

Shenzhou IV

From June, 5438 to February, 2002, Shenzhou IV was successfully launched at 0: 30 on the 30th, breaking the historical record of low-temperature launch in China. On June 5, 2003, the spacecraft returned safely and completed all the scheduled test contents.

Shenzhou IV has the same technical status as a manned spacecraft except that there is no manned spacecraft. During the flight, the spacecraft has completed the tasks of earth observation, material science, life science experiment, space astronomy and space environment detection.

Shenzhou v

China's first manned spacecraft, Shenzhou 5, was successfully launched on June 5, 2003. Yang Liwei, the first astronaut in China, became the first China tourist in the vast space.

Shenzhou 5's 2 1 hour 23-minute space trip marks that China has become the third country in the world to independently carry out manned space activities after Russia and the United States.

Shenzhou VI

June 65438+1October 65438+February 2005, China's second manned spacecraft Shenzhou VI was successfully launched, and the astronaut fee and Nie Haisheng were successfully sent into space. /kloc-in the early morning of 0/7, after a space flight of 1 15 hours and 32 minutes, the spacecraft's return capsule landed smoothly.

Shenzhou VI carried out the first multi-person and multi-day flight test of China's manned spaceflight project, and completed the space science experiment in which China really participated.

Shenzhou vii

On September 25th, 2008, China's third manned spacecraft Shenzhou VII was successfully launched, and three astronauts Zhai Zhigang, Liu Boming and Jing Haipeng were successfully launched.

On 27th, Zhai Zhigang, dressed in the "Tian Fei" extravehicular spacesuit developed by China, got out of the cabin 19 minutes and 35 seconds with the help of Liu Boming, dressed in the Russian "Seahawk" extravehicular spacesuit. China has become the third country in the world to master the technology of extravehicular activities.

On the evening of September 28th, 2008, Shenzhou VII spacecraft successfully landed in Gulang Grassland, A Mu, Central Inner Mongolia after successfully completing extravehicular activities and a series of space science experiments.
