Design and Implementation of an On-orbit Maintenance Method for the Interior Decoration Materials in a Manned Spacecraft Habitation Module

Maintainability is one of the primary characteristics that a manned spacecraft should possess. There are lots of interior decoration materials in the manned spacecraft habitation module. Realization of on-orbit maintenance on interior decoration materials with the help of astronauts can improve the work efficiency and life conditions of astronauts significantly, which is very important for construction of the space station. In this paper, a method of on-orbit maintenance on interior decoration materials in a manned spacecraft habitation module is proposed and practically applied to an on-orbit maintenance program on interior decoration materials. After sufficient verification on the ground, the program was carried out by astronauts in a manned spacecraft, and it showed that the method is correct and effective. The method can provide an important reference for the design of on-orbit maintenance in manned spacecraft.
