Abstract: With the continuous progress of human society and the rapid development of aerospace science and technology, cislunar exploration and exploitation is entering the stage of large-scale and industrialization. Cislunar aerospace transportation system is an important component of large-scale cislunar exploration and exploitation, supporting various activities of cislunar exploration and exploitation. Firstly the global development status and trends of cislunar aerospace transportation are introduced in this paper. Then the composition of the cislunar aerospace transportation system is given, and the capacity demands in the future are predicted based on an analysis of future development needs. Facing to the large-scale and low-cost cislunar aerospace transportation in future, One-stop solution and Relay-style solution are proposed. At last according to the typical mission requirements of lunar landing and return, the propellant refueling and system scale requirements of two solutions are analyzed. The paper will provide reference for cislunar aerospace transportation system development.
