The National Natural Science Foundation of China has outlined a 5-year plan to explore the construction of massive structures in space, including spacecraft up to a kilometer long. The plan also targets the development of giant space telescopes and modular power plants. These structures aim to surpass the size of the International Space Station. The rapid advancement of space technology necessitates new methods for launching, deploying, and manufacturing spacecraft. Analysts suggest that in-space construction could enhance spacecraft performance and reduce operating costs.
