Outline of Final Research Achievements

Soil mechanics study plays a key role in the future lunar/planetary surface explorations relating to various soil-related problems including lunar module landing, mobile robot locomotion and earth-moving. Lunar soil mechanics investigation system (LSM) is proposed as a candidate instrument for Japan's future lunar landing program. The LSM is configured to perform four types of measurement in a borehole; 1)1-m borehole preparation and measurement while drilling, 2)borehole optical sensing, 3)borehole shear testing, and 4)vertical seismic profiling. In this study, we developed prototypes of drilling augers, borehole shear testing probes and reverse vertical seismic profiling (RVSP) system and demonstrated a series of model experiments with a Japanese lunar soil simulant (FJS-1). The test results showed that the proposed methods have a potential to be reliable tools.
