The successful launch and recovery of the Shenzhou experimental spacecraft has become another milestone in China's space history. The success date is1999165438+10.21,which is only one month and nine days away from the end of the year. For seven years, many astronauts who count down their calendars every day just want to have a good sleep. But such a simple wish is also an unattainable luxury for many people. In the new drums, "Shenzhou II" set off again. Chinese astronauts driving rumbling cranes into space must race against time for the country's ideals! ?
Soon, the second spaceship "Shenzhou II" was manufactured, with more advanced performance than "Shenzhou I", and more complete installation of safety equipment and life support system. ?
20011was launched from Jiuquan Satellite Launch Center and successfully returned to the ground after 7 days' flight. This is the prototype of China's first unmanned spacecraft. Experiments in the fields of space life science, space materials, space astronomy and physics in microgravity environment were carried out on the spacecraft. All kinds of instruments and equipment have stable performance and work normally, and a large amount of data has been obtained.
Compared with Shenzhou-1 spacecraft, Shenzhou-2 spacecraft has a new expansion in system structure and a new improvement in technical performance, and its technical status is basically the same as that of manned spacecraft. ?
Then the Shenzhou III spacecraft was launched on March 25th, 2002. The spacecraft is equipped with a human metabolism simulator, anthropomorphic physiological signal equipment and a human dummy, which can quantitatively simulate important physiological activity parameters such as astronauts' breathing and blood circulation. The orbital module of Shenzhou III has been in orbit for more than 180 days, and a series of space science experiments have been successfully carried out. ?
On February 30th, 2002, the launch of Shenzhou IV was the last rehearsal for China's manned space flight. It was a flight test with the highest technical requirements, the most complete test system and the most difficult since the implementation of the manned space project, and it also faced the most severe test since the manned space launch:
The launch site is extremely cold, the lowest temperature is close to -30℃, which exceeds the low-temperature launch condition by nearly 10℃, and the launch of the spacecraft has entered an irreversible state. The final successful launch of Shenzhou IV spacecraft indicates that China's manned spaceflight project has withstood the most comprehensive flight test in unmanned state, creating a new record of low-temperature launch in China's space history and a miracle of rocket low-temperature launch in the world's space history.
Academician Liang, an aerospace expert from China, said that although shenzhou spaceship's development and launch were later than those of the United States and Russia, China's starting point for developing spacecraft was higher. The orbital module of Shenzhou spacecraft can not only observe the earth from orbit, but also be used as an aircraft for future rendezvous and docking, which is an excellent tool for future round-trip transportation between heaven and earth. ?
10/0 On October 6, the Associated Press released a message to the world: Before the manned spacecraft was about to be launched, China announced that it would put a lunar exploration satellite into lunar orbit within three years at the earliest. China's lunar exploration program, code-named "Chang 'e Project", was launched in March this year and is progressing smoothly. It is also known that if all goes well, China people may appear on the moon in 10. ?
The year 2003 was an unusual day. At 9 o'clock sharp, Yang Liwei's Shenzhou 5 spaceship took off in the roar of the earth-shaking. On this day, people all over the world saw Yang Liwei from China flying in space. From this day on, China's five-star red flag began to appear among the flags flying in the vast universe. The "God Ship" carrying the hope of the whole nation has opened a brand-new space age in China. ?
June+10/October 65438+At 6: 23 in the morning of June 2003, the China "Shenzhou 5" spacecraft landed on the open grassland in Inner Mongolia after taking off for 2 1 hour. The history of China's footprint in space has come to an end. June 65438+10/October 65438+February 2005, China successfully launched the manned spacecraft Shenzhou VI again, and conducted the first multi-person and multi-day space flight test. ?
On September 25th, 2008, 2 1: 10, the Long March II F carrier rocket carried the Shenzhou VII manned spacecraft, carrying the dream of China people to reach new heights in space and fly into space. This is the seventh time that shenzhou spaceship flew into space and the third time that China people landed in space. ?
After Yang Liwei realized the Chinese dream, Fei and Nie Haisheng entered the orbital module to conduct space science experiments, today, three China astronauts Zhai Zhigang, Liu Boming and Jing Haipeng shoulder a brand-new historical mission-according to the plan, they will walk out of the module during this space flight.
