Mastcam planned a large mosaic to image the top and bottom of the Pinnacle Ridge scarp, complementing the Mastcam mosaic that was acquired over the weekend. ChemCam included a long distance RMI image of the face of the ridge with intriguing tonal and textural variations. The targeted science block on sol 4178 also includes a MAHLI mosaic of an interesting layered rock in our workspace, “El Portal,” that will be characterized and imaged by ChemCam LIBS and Mastcam. Lastly, Mastcam will take a small mosaic of a rock in the workspace, “Bairs Creek,” to investigate interesting textures and features that were created by the wind.
