At 6:30:07 on November 20, 1999, my country's first test spacecraft "Shenzhou" 1 successfully launched. China became the third country in the world to possess manned space technology after the United States and Russia. After completing 21 hours of space science experiments, it successfully landed at 3:41 on the 21st. The successful launch and recovery of the "Shenzhou" experimental spacecraft has become another milestone in my country's aerospace history. The date of success was November 21, 1999, only one month and nine days before the end of the year. Among the astronauts who have been counting down the calendar every day for seven years, many just want to have a good sleep. But even such a simple wish is an unattainable luxury for many people. Amid the new beats of war drums, "Shenzhou-2" began to take off again. The Chinese astronauts who are driving the rumble skytrain into space must race against time for the ideal of a nation!
Soon, the second spacecraft "Shenzhou 2" was built. Its performance was more advanced than that of "Shenzhou 1", and the equipment to ensure safety and life support systems was also more fully installed.
It was launched from the Jiuquan Satellite Launch Center on January 10, 2001, and successfully returned to the ground after 7 days of flight. This is our country’s first full-scale unmanned spacecraft. Experiments in the fields of space life science, space materials, space astronomy and physics were carried out on the spacecraft in a microgravity environment. Various instruments and equipment performed stably and worked normally, and a large amount of data was obtained. Compared with the "Shenzhou" 1 spacecraft, the system structure of the "Shenzhou" 2 spacecraft has been newly expanded and its technical performance has been further improved. The technical status of the spacecraft is basically the same as that of the manned spacecraft.
Then the Shenzhou-3 spacecraft was launched on March 25, 2002. The spacecraft is equipped with a human metabolism simulation device, anthropomorphic physiological signal equipment and a body dummy, which can quantitatively simulate important physiological activity parameters of astronauts' breathing and blood circulation. The "Shenzhou" 3 orbital module remained in orbit for more than 180 days and successfully conducted a series of space science experiments.
The launch of the "Shenzhou" 4 spacecraft on December 30, 2002 was the last rehearsal of China's manned spaceflight. It has the highest technical requirements and the most comprehensive test systems since the implementation of the manned spaceflight project. , the most difficult flight test, it also faces the most severe test since manned space launch: the rare severe cold in the history of the launch site, the lowest temperature is close to -30°C, exceeding the low-temperature launch conditions by nearly 10°C, and the spacecraft launch has entered an irreversible state . The final successful launch of the "Shenzhou" 4 spacecraft marks that China's manned space project has withstood the most comprehensive flight test test in an unmanned state, setting a new record for low-temperature launches in China's space history, and also creating a rocket in the world's space history. The miracle of cryogenic launch. Academician Liang Sili, a Chinese aerospace expert, said that although the development and launch of the "Shenzhou" spacecraft were later than those of the United States and Russia, my country's spacecraft development starting point is higher. The orbital module of the "Shenzhou" spacecraft can not only conduct orbital Earth observation, but also serve as an aircraft for future space rendezvous and docking. It is an excellent tool for transportation back and forth between heaven and earth in the future.
On October 6, the Associated Press announced to the world: Before the launch of a manned spacecraft, China announced that it would send a lunar exploration satellite into lunar orbit within three years at the earliest. China's lunar exploration program, code-named "Chang'e Project", started in March this year and is currently progressing smoothly. It is also reported that if all goes well, Chinese people may appear on the moon in 10 years.
October 15, 2003 AD was an unusual day. At 9:00 sharp, the "Shenzhou" 5 spacecraft on which Yang Liwei was riding took off into the sky with a shocking roar. People all over the world saw Chinese Yang Liwei flying in space on this day. From this day on, China’s five-star red flag began to appear among the flags fluttering in the vast universe. That "magic boat" carrying the hope of the entire nation opened up a new aerospace era for China.
At 6:23 a.m. on October 16, 2003, China's "Shenzhou 5" spacecraft landed smoothly on the open grasslands of Inner Mongolia 21 hours after takeoff. This ends the history of no Chinese footprints in space
On October 12, 2005, China successfully launched the manned spacecraft Shenzhou-6 again and conducted its first multi-person, multi-day space flight test.
At 21:10 on September 25, 2008, the Long March 2F carrier rocket flew into space carrying the Shenzhou 7 manned spacecraft, carrying the Chinese nation's dream of reaching new heights in space.
This is the seventh time that the Shenzhou spacecraft has flown into space, and it is also the third time that Chinese people have gone into space.
After Yang Liwei realized the Chinese nation’s dream of flying into space, and Fei Junlong and Nie Haisheng entered the orbital module to carry out space science experiments, today, the three Chinese astronauts Zhai Zhigang, Liu Boming, and Jing Haipeng are on their golden autumn journey, shouldering the responsibility of A new historic mission - according to the plan, they will achieve extravehicular walking during this space flight.

At 18:05 on October 24, 2007, the Long March-3A carrier rocket carrying China's first lunar exploration satellite Chang'e-1 was successfully launched from the No. 3 tower of the Xichang Satellite Launch Center. At 18:59:57 on October 1, 2010, Chang'e-2, the sister satellite of Chang'e-1, was launched from the Xichang Satellite Launch Center and achieved a complete success. The purpose of this launch is mainly to achieve the next step of soft landing on the moon, conduct some key technology tests, and conduct high-precision imaging of the Chang'e-3 landing area. Extended information China's aerospace history began in February 1956, when the famous scientist Qian Xuesen proposed the "Opinions on Establishing China's Defense Aviation Industry" to the central government. In April 1956, the Aviation Industry Commission of the People's Republic of China was established to provide unified leadership for China's aviation and rocket industry. Nie Rongzhen serves as the director, and Huang Kecheng and Zhao Erlu serve as deputy directors. The establishment of the Aviation Industry Committee marks the beginning of China's aerospace industry. Zhao Xiaojin, Minister of the Aerospace Department of China Aerospace Science and Technology Corporation, told the media before the launch of the "Chang'e-1" satellite that the "Chang'e-1" launch window has been reserved for 35 minutes, and it can be launched within these 35 minutes. But compared with launching in the first minute, the satellite fuel will be lost by 120 kilograms in the last minute. This is a huge loss for the "Chang'e-1" which has only 1,200 kilograms of fuel in total and will directly affect its mission. Working hours and working life. If the normal launch cannot occur within these 35 minutes due to special reasons, the launch plan will have to be canceled and the launch window will be re-determined until the next year.
