PIA18444: Hollows in Balanchine Crater

Hollows in Balanchine Crater


One of our highest resolution views yet inside the beautiful Balanchine crater reveals the bright hollows that cover portions of the crater. (See also this lower resolution view taken in 2011, before Balanchine crater was named.) The hollows appear to reside not just on the floor, but on portions of the slumped crater walls as well.

This image was acquired as a targeted set of stereo images. Targeted stereo observations are acquired at resolutions much higher than that of the 200-meter/pixel stereo base map. These targets acquired with the NAC enable the detailed topography of Mercury's surface to be determined for a local area of interest.

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. 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 .
