PIA19187: Peaks and Hollows

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.

Background Info:

The MESSENGER spacecraft is the first ever to orbit the planet Mercury, and the spacecraft's seven scientific instruments and radio science investigation are unraveling the history and evolution of the Solar System's innermost planet. During the first two years of orbital operations, MESSENGER acquired over 150,000 images and extensive other data sets. MESSENGER is capable of continuing orbital operations until early 2015.

For information regarding the use of images, see the MESSENGER image use policy .
