Mastcam is taking several mosaics this weekend (must have gotten extra energy from the Halloween sugar!). Close to the rover, Mastcam will acquire single-frame images of the targets Hoist Ridge and Eureka Valley, and a small mosaic of some surficial troughs just a little further away. Moving further afield, a small 3×1 mosaic (three images in one row) will image the same area as the ChemCam RMI of the Gediz Vallis ridge, and a larger 9×2 mosaic will focus on the faraway yardang unit, where we hopefully will be in a few years.
