Most of this 13.3-km-diameter (8.3-mi.-diameter) crater, located approximately 265 km (165 mi.) northwest of Angkor Vallis, is engulfed in shadows. The morning Sun was low in the sky (high incidence angle) when this image was acquired, emphasizing the topography. Two large ejecta blocks located north of the shadowed rim near the right hand side of the image cast long shadows. The larger of these blocks is approximately 100 m in diameter. Using trigonometry and knowledge of the incidence angle, the height of the block can be calculated: ~27 m (~89 ft.).

This image was acquired as part of the MDIS low-altitude imaging campaign. During MESSENGER's second extended mission, the spacecraft makes a progressively closer approach to Mercury's surface than at any previous point in the mission, enabling the acquisition of high-spatial-resolution data. For spacecraft altitudes below 350 kilometers, NAC images are acquired with pixel scales ranging from 20 meters to as little as 2 meters.

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.
