The geostationary orbit (GEO) plays an important role in human spaceflight for its perfect orbital characteristics.With the GEO resources becoming more and more limited,it is urgent to clean up GEO debris.In view of the space debris on the GEO,a GEO on-orbit service plan "Nu Wa" is proposed to realize the on-orbit manufacturing capability based on space debris with the on-orbit recovery,3D printing,on-orbit assembly and other key technologies.Besides,the paper also makes a systematic analysis of the plan from the aspects like task demands,mission,task flow,system composition and conceptual design of satellite system.
