Peaks and Hollows

The surface shown here is located within a 73-km-diameter crater; the mounds are part of a larger central peak structure of the hosting crater. The resolution of this image resolves hollows on the central peaks, as seen in other craters such as Ahmad Baba, Mickiewicz, and others. The lower right also shows hollows that appear to form in one layer of a crater wall, such as has been viewed in other high-resolution images. This image was acquired as part of the NAC ride-along imaging campaign. When data volume is available and MDIS is not acquiring images for its other campaigns, high-resolution NAC images are obtained of the surface. These images are designed not to interfere with other instrument observations but take full advantage of periods during the mission when extra data volume is available.
