Of Interest: Wall terraces are landforms common to impact craters and basins across Mercury. The fault-bound cliff in this image forms part of the wall of an unnamed peak-ring basin (which also hosts hollows). The low-angle lighting in the scene creates dramatic shadows at the base of the rim terrace, which is almost 1.5 km (1 mi.) high.

This image was acquired as a high-resolution targeted observation. Targeted observations are images of a small area on Mercury's surface at resolutions much higher than the 200-meter/pixel morphology base map. It is not possible to cover all of Mercury's surface at this high resolution, but typically several areas of high scientific interest are imaged in this mode each week.

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.
