This mosaic view from the Mast Camera (Mastcam) on NASA's Mars rover Curiosity shows textural characteristics and shapes of an outcrop called "Point Lake."

The NASA Mars rover Curiosity used its Mast Camera (Mastcam) during the mission's 120th Martian day, or sol (Dec. 7, 2012), to record this view of a rock outcrop informally named "Shaler."

Large-scale crossbedding in the sandstone of this ridge on a lower slope of Mars' Mount Sharp is typical of windblown sand dunes that have petrified. NASA's Curiosity Mars rover used its Mastcam to...
