The HiRISE camera on NASA’s Mars Reconnaissance Orbiter took a huge, detailed image of Mars‘ Mojave Crater on January 7, 2007. The image shows the central uplift structure in the crater. Rocks that form this peak were several kilometers beneath the surface until an impact formed the 60 kilometer-diameter crater just north of Mars‘ equator. The HiRISE image also shows that boulders as large as 15 meters across have eroded from the massive uplifted rock and rolled downslope.
