During the launch of Shenzhou 5 manned spacecraft, the escape system of the Long March 2F rocket will provide protection for astronauts for the first time. Before launch 15 minutes, the automatic fault detection and processing system on the rocket can automatically detect faults and give an alarm if there is any problem.
The launch vehicle for launching manned spacecraft should not only have a large carrying capacity, but also have higher reliability and safety than the launch vehicle for launching satellites, because it is "manned". According to reports, the uniqueness of the "Long March" 2F rocket is that the rocket made in China is designed according to safety for the first time, and the reliability index is improved from 0.9 1 of unmanned rockets to 0.97, that is, only three problems may occur after launching 100 rockets; The astronaut's safety index is 0.997, that is, there are 1000 dangers, and only three rescues failed.
At present, there are 12 monitoring points in shenzhou spaceship. The land is Beijing, Xi 'an, Weinan, Qingdao, Xiamen, Kashgar, Karachi and Namibia, and the sea is the Sea of Japan, the southern tip of South America, the Atlantic Ocean and Australian waters, which are undertaken by four monitoring vessels "Roy" and are headquartered in Beijing. Shenzhou 5's return instruction was issued by Wang Yuan-3 TT&C spacecraft. Chang 'e V will be launched from Jiuquan Launch Center. The main landing site of the return capsule is in a Gobi in Bawangqi, Inner Mongolia, and the auxiliary landing site is in Jiuquan. These arrangements are the same as those of Shenzhou IV.
Shenzhou 5 has further improved the emergency rescue system of the spacecraft, and carefully designed the rescue plan from takeoff to landing.
Regarding the safety of astronauts, Academician Qi Faren, the chief designer of Shenzhou 5, once said that China is confident to ensure the safety of astronauts. He said: "We have a principle when designing the spacecraft, that is, every system of the spacecraft should be' a fault, flying normally; Secondary failure, safe return'. "
