Summary:We describe the recent progress and development of a compressed CO 2 hard rock drill for Mars that is intended to facilitate the extraction and retrieval of deep, subsurface samples. A deep drill system is necessary to access lacustrine deposits dating from the Mars Noachian geologic period that is thought to have had an abundance of surface water, conducive to the possible presence of microbial life. We describe the science goals that determine drill depth and extraction system objectives, impact tower testing needed to define performance, the function of a Down-The-Hole (DTH) drill bit, and proposed system level mechanisms. Recent prototyping, testing, and results are reported.
