Research Progress of Penetration and In-Situ Detection of Planetary Regolith Physical Properties

Kinetic penetration is an effective method for in-situ detection of planetary regolith, especially for geological structure and physical and chemical properties. The research status and development trends of the penetrating-type in-situ detection of planetary profiles are investigated and its critical techniques and solutions are summarized. According to China’s general plans of future deep space exploration and critical technology requirements, penetrating-type in-situ investigation perspectives are put forward for lunar, Mars, and asteroid respectively, which will provide new methods and new schemes for the project argumentation and key technology research of the extraterrestrial object exploration project in China.
