Curiosity Returns to Missoula: Exploring the Stimson-Pahrump Contact with ChemCam and Mastcam Imaging

Curiosity’s successful drive of 19 meters on Sol 1067 brought it back to Missoula for further science research. The mission’s goal is to conduct a detailed study of the Stimson-Pahrump contact and determine the timing of the veins observed there. On Sol 1068, ChemCam LIBS will be used on four different “Missoula” targets (Missoula A, B, C, and D) to understand the chemistry across the contact. Several Mastcam images will also be taken to document these targets. On Sol 1070, ChemCam will make a passive observation on the target “Coombs” and conduct a regular ChemCam LIBS observation on the target “Stenerson.” Environmental monitoring activities will also be conducted over the weekend to evaluate the atmosphere’s opacity and search for dust devils.

After thoroughly investigating an outcrop with ChemCam, Curiosity resumed driving through Marias Pass on Sol 1070 and took post-drive imaging in preparation for upcoming science activities. Lauren Edgar, a Research Geologist at the USGS Astrogeology Science Center and a member of the MSL science team, provided this update. Keep in mind that planned rover activities are subject to change based on factors such as environmental conditions, communication relays, and rover status.
