The more information about Shenzhou 5, the better.

(of an emperor or a great general) divine and mighty

The successful realization of China's first manned space flight by Shenzhou 5 spacecraft fully shows that many key technologies on China spacecraft and rockets are already in the leading position in the world.

The technology of thermal protection material for the outer wall of the return capsule is one of the key technologies in Shenzhou 5, and it is the real model of thermal protection material. In order to make the astronauts have a comfortable and safe environment in the return capsule, after many experiments, the developer finally selected a low-density ablative heat protection material, so that even when the temperature outside the capsule is from-100 degrees to 3000 degrees above zero, the temperature inside the spacecraft can be kept at about 20 degrees above zero. "

There are many original technologies like this in the development of shenzhou spaceship. As the first generation manned spacecraft in China, Shenzhou 5 has gone beyond the design of single cabin and double cabin, and directly adopted the multi-functional spacecraft scheme consisting of three cabins. Although Shenzhou 5 only carried one astronaut this time, our design can carry three people at the same time.

Qi Faren, chief designer of shenzhou spaceship, said: "The (Shenzhou) spacecraft started relatively late, but our starting point was relatively high, and we reached the designated position in one step. Where are we? We used three cabins at a time and added an extra cabin, which enabled our ship to go back and forth between heaven and earth at one time.

After the astronauts of Shenzhou 5 spacecraft return to the ground, the orbital module will work autonomously in space like a satellite without being attended, which greatly prolongs the working life of the spacecraft in space applications and scientific experiments.

The return capsule of Shenzhou 5 spacecraft is 2.2 meters high, which is equivalent to a room of 6 square meters. It is the largest spacecraft return capsule in the world at present. In order to ensure the safe return of the three-ton return capsule to the ground, the developer also designed the world's largest landing umbrella for the return capsule with an area of 1.200 square meters, which was used to slow down the spacecraft and reduced the landing speed of the return capsule by more than 20 times in ten minutes.

Lu Yongxiang, President of Chinese Academy of Sciences: It shows that China's aerospace industry has not reached the general level, and has entered the advanced ranks in the world. Its reliability, carrying capacity, control system and safety guarantee system have all reached the top three positions in the world.
