Abstract: The concept of cislunar exploration and exploitation is put forward firstly in this paper. The global development status and trends are summarized, and the development demands are described from perspectives of human civilization, the pattern of space, strategic security and sci tech/economy development. The architecture composition, functional requirements, technical difficulties are proposed. The development benefits are analyzed from three aspects of science, economy and engineering. Finally, the development roadmap is given. The research results can provide reference for large scale exploration and exploitation of cislunar space in the future.

Key words: Cislunar space, Space exploration, Aerospace transportation system, Space infrastructure
