Evolution of Sample Tube Preparation Techniques for Planetary Drill Testing

Introduction Electric Vehicle Controllers (EVC) and the Northern Centre for Advanced Technology (NORCAT) have created two generations of Lunar Highland Simulant ?Simulant preparation techniques and equipment resulted from drilling activities in support of Regolith and Environment Science and Oxygen and Lunar Volatiles Extraction (RESOLVE ) ?The purpose of defining the compaction process was to minimize the effect of density on drill testing This allowed other variables including drill bit geometry, auger, RPM, and thrust to be evaluated independent of density ?Density of Highland Regolith falls within a range of 1.40 to 2.29 g/cm3 (p484 Lunar Source Book)
