Study reveals lunar regolith evolution process on Chang’e-4 landing area

A research team led by Prof. Di Kaichang from the Aerospace Information Research Institute (AIR) of the Chinese Academy of Sciences (CAS) and their collaborators have established an evolution model with simple craters in the Chang’e-4 landing area. The research results reveal the evolution process of lunar regolith and quantify the overturning and mixing effect of small simple impact events on lunar regolith.
