Caption:
MESSENGER continues to image the surface of Mercury at ever higher resolutions. In this view, we can see the southeastern rim of the Bechet impact crater, located in Mercury's northern volcanic plains . Bechet is 17.6 km (10.9 miles) in diameter. At this resolution (about 10 meters per pixel), the texture on the crater's inner wall is clearly visible. This texture is distinct from that of the crater floor, and may be due to the down-slope creeping of wall material. There also appears to be a subtle change in slope along the wall, which could be an incipient slump .
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.

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.
