1975165438+1On October 26th, China's first recoverable satellite was successfully launched and returned three days later. China became the third country in the world to master the technology of satellite return.
1992, China manned spacecraft was officially included in the national plan, and this project was later named "Shenzhou" manned spaceflight project. "Shenzhou" manned space flight project is the largest and most complicated space flight project in China from the end of 20th century to the beginning of 26th century.
1999165438+1On October 20th, China's first unmanned experimental spacecraft "Shenzhou-1" was launched in Jiuquan, and landed successfully in the recycling yard in central Inner Mongolia 2 1 hour later.
At 2001110/,the Shenzhou II unmanned spacecraft independently developed by China was launched from Jiuquan Satellite Launch Center.
At 7: 00 pm on June 5, 2003, at 65438, Shenzhou IV landed in a predetermined area in central Inner Mongolia and was successfully recovered. At 0: 40 on February 30, 65438, the Shenzhou IV unmanned spacecraft was launched from Jiuquan Satellite Launch Center.
On March 25th, 2002, Shenzhou III was successfully launched from Jiuquan Satellite Launch Center. On April 1 day, the hatch cover of Shenzhou III, which successfully landed in central Inner Mongolia, was opened, and the sun shone on the face of the simulated astronaut. The anthropomorphic load test achieved good results and the simulated astronauts were safe and sound.
From February 30, 2002 to October 5, 2003/kloc-0, Shenzhou IV unmanned spacecraft was successfully launched in the cold of minus 20 degrees Celsius, and returned safely after flying for seven days.
June 5438+1October 65438+May 2003, China's first astronaut, Yang Liwei, went into space in the Shenzhou 5 spacecraft, realizing the Chinese nation's dream of flying for thousands of years.
June 65438+1October 65438+February 2005, astronauts Fei and Nie Haisheng flew into space again in the Shenzhou VI spacecraft, spent five days in space, and returned to the ground safely after completing a series of space experiments.
At 9: 00 pm on September 25th, 2008, China astronauts Zhai Zhigang, Liu Boming and Jing Haipeng flew into space on Shenzhou VII. On September 27th, 2008, at 16: 43 pm Beijing time, the astronaut Zhai Zhigang of China Shenzhou VII manned spacecraft successfully got out of the cabin and carried out China's first space extravehicular activity. On September 28th, 2008 17: 37 Beijing time, the Shenzhou VII return capsule, which spent more than two days in space, landed successfully. 18: 23, three astronauts, Zhai Zhigang, Liu Boming and Jing Haipeng, successfully left the cabin. China Shenzhou VII manned space flight was a complete success.
From 1999 to 2005, in six years, six spaceships and six leaps, the speed and efficiency of China's manned space flight amazed the world, and also inspired and proud hundreds of millions of people in China.
In six years, six spaceships and six breakthroughs, China astronauts used their wisdom and efforts to make up for the lack of material and technical foundation and created a rapid leap in manned space flight in China.
Although China is short of materials, it has done its best every time, striving for perfection, and its success rate ranks first in the world.
