We selected two contact science targets to investigate in our attempt to answer these questions. The target named “Buttermilk” is one of the skinny raised ridges associated with these cracks. We will be placing APXS at three different places over this feature to try to characterize its chemistry. Our second contact science target, “Lee Vining,” gives us a nice 3D view into these cracks. Here, we will collect two MAHLI mosaics, one on each side of the rock that’s close to the rover, to characterize the geometry of the fractures. ChemCam will also get in on the action with a LIBS observation on a fracture fill named “Crater Crest,” as well as an observation on a dark-toned, platy rock called “Lost Arrow.” Mastcam will collect observations of several more polygonally fractured rocks further away from Curiosity in “The Dardanelles” series of mosaics. Some environmental science observations will round out the plan before our drive will take us about 25 meters further (about 82 feet) to the southwest.
