Observations by the Mars Science Laboratory Mast Camera (Mastcam) in Gale crater reveal isolated outcrops of cemented pebbles (2 to 40 millimeters in diameter) and sand grains with textures typical of fluvial sedimentary conglomerates. Rounded pebbles in the conglomerates indicate substantial fluvial abrasion. ChemCam emission spectra at one outcrop show a(More)

The Mars Exploration Rovers (MER) use a manin-the-loop system for control in most cases. While capable of some autonomous driving, all arm operations and most drives are planned on the ground. Planning these operations requires a precise knowledge of the terrain surrounding the rover: where are the rocks, the sand, the hazards. This terrain is derived from(More)
[1] We have assessed the characteristics of clasts along Curiosity’s traverse to shed light on the processes important in the genesis, modification, and transportation of surface materials. Pebbleto cobble-sized clasts at Bradbury Landing, and subsequently along Curiosity’s traverse to Yellowknife Bay, reflect a mixing of two end-member transport(More)
