General Technology of Cargo Ship

Abstract

Cargo ship is an important foundation and guarantee for the construction and long-term operation of space station. As a near-Earth orbit spacecraft, the space station needs to be supplemented with non-renewable resources such as constantly consumed propellant and nitrogen. In order to give full play to the advantage of manned on-orbit maintenance, it is necessary to transport spare equipment and replace faulty ones to prolong the on-orbit flight life of the space station. The supplies consumed by astronauts in their on-orbit work and life need to be transported from the ground to ensure long-term on-orbit astronaut stay.
