Abstract: Based on the research results of lunar soil (chemical composition, physical and mechanical characteristics, etc.), the development of the lunar soil simulant both at home and abroad is comprehensively reviewed in this paper. The lunar soil simulant used in the Chinese Lunar Exploration Program is specially addressed. It is used for the calibration of scientific instruments, the full-scale landing-impact test, the mobility test of the lunar rover, the sampling test of the lunar probe, and others. The raw materials, the production process in factories and the preparation process in a test yard are described. The research proposals are made for the mission requirements of the manned lunar landing program in the future.
