To develop a reliable drilling tool for lunar soil sampling,it is necessary to do the drilling experiments in the lunar soil during the research.The real lunar soil is too rare to acquire on the Earth,so it is an essential approach of the lunar drilling tool research that uses the lunar soil simulant that can simulate the main physical and mechanical characteristics of the real lunar soil.This paper briefly expounds the lunar soil simulant that is needed in the research of drilling bit based on the summary of the real lunar soil and lunar soil simulant research.
