Hong Guang's space energy suit has the functions of keeping the astronaut's body temperature, keeping the pressure balance (making the pressure on the astronaut similar to that on the earth), blocking strong and harmful radiation (such as radiation from the sun), treating the astronaut's excrement, providing oxygen and pumping out carbon dioxide.

The atmosphere provides all kinds of protection for the earth's residents, including space suits: providing oxygen, eliminating carbon dioxide, preventing radiation, controlling temperature and pressure, and allowing astronauts to live safely in space for 9 hours.
