Seven major systems of China's manned space engineering

The Astronaut system is responsible for the selection and training of astronauts, medical supervision and medical support for astronauts, and medical requirements for spacecraft engineering design.

The spacecraft application system is a practical system that is closely related to people's life and environment. The application system is equipped with many scientific experimental instruments in the spacecraft for Earth observation and various scientific experiments.

The Manned Spacecraft system consists of 13 sub-systems. The spacecraft consists of the propulsion, orbital, return and additional sections. The orbital and return cabins are both sealed and are the places where astronauts are operating.

The launch vehicle system is a means of transporting a spacecraft into space. China's manned space engineering uses the launch rocket "changzheng 2 F", which is currently the highest, heaviest, and most powerful rocket in China.

The launch site system is undertaken by the manned space launch site of the Chinese Jiuquan Satellite Launch Center, responsible for testing and launching spacecraft and rockets.

The landing field system is responsible for searching and searching for astronauts and returning to the cabin for recovery. It is necessary to find and open the returning hatch door within the first time the spacecraft returns to rescue astronauts.

The aerospace measurement and control and communication system is responsible for the whole process of measurement and remote control from the launch, operation to the final return of the spacecraft after the spacecraft is ignited and launched. It is the only link between the spacecraft and the ground after it is lifted. (Edit: Zhang Ying)
