Shenzhou spaceship is 9 meters high, with a take-off weight of more than 8 tons and a maximum diameter of 2.8 meters. The top part is called the orbital module, which is also the living area of astronauts. Astronauts' on-orbit supporting equipment, including rendezvous and docking sensors, should be installed in the orbital module. When the spacecraft runs alone, it is also the place where astronauts live.
The main function of the orbital module is to carry many rendezvous and docking sensors, which are responsible for rendezvous and docking with the space station, and also provide an environment for astronauts to live and work in orbit during their independent flight.
The cabin located in the middle of the spacecraft is the return cabin, the only cabin that will return to the ground, and it is also the control center of the whole spacecraft. The control computer and all kinds of communication equipment of the spacecraft are mainly concentrated in the return cabin, and astronauts travel back and forth between heaven and earth by spacecraft.
There are some core control components in the cabin, including attitude measurement and attitude control of the return cabin. At the same time, some instruments and equipment of astronauts are also in the return cabin, and astronauts mainly operate in the return cabin during their independent flight.
The lowest cabin of the spacecraft is called the propulsion cabin, which is loaded with the propulsion system, power supply, thermal control and measurement and control equipment of the spacecraft to provide energy, power and communication guarantee for the spacecraft.
"God XIV" is more reliable and safer.
According to reports, the Shenzhou 14 spacecraft completely inherited the technical status of the Shenzhou 13 spacecraft, and its main functions and technical indicators remained unchanged. On this basis, according to the mission requirements of the space station, the developers improved the adaptability of Shenzhou 14, made the spacecraft safer and more reliable, and escorted the life safety of astronauts.
