The National Natural Science Foundation of China has outlined a five-year project for researchers to study the assembly of ultra-large spacecraft. Preliminary research is to include studying the challenges of developing lightweight structures and on-orbit assembly and control. The project would have practical applications for potential megaprojects including colossal space-based solar power stations.The project would focus on minimizing the weight of the spacecraft to reduce the number of launches and construction.
