Review of research about lunar drilling technology

Abstract:

The successful launch of the “Chang’e 5” probe has opened the prelude to the return of samples from the moon in China. To meet the current requirements of lunar （or deep space in future） exploration， drilling technology， as the most commonly used method to obtain deep geological samples， is receiving more and more attention. However， in the face of the extreme environment of the moon （or deep space in the future）， the earth’s conventional machinery and craftsmanship cannot be directly transplanted. Therefore， this paper has conducted surveys and statistics on the current progress of lunar drilling technology in various countries， including several areas such as researching the properties of lunar soil， developing of lunar soil simulant， the impact of lunar environment acted on drilling， the structure and parameters designed for lunar drilling equipment， and optimization of lunar drilling regulations， and conducted thinking of future lunar drilling.
