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.
