Summary

Description	English: Date acquired: April 22, 2011 Image Mission Elapsed Time (MET): 211938059 Image ID: 161520 Instrument: Wide Angle Camera (WAC) of the Mercury Dual Imaging System (MDIS) WAC filter: 7 (748 nanometers) Center Latitude: 53.40° Center Longitude: 245.4° E Resolution: 216 meters/pixel Scale: The crater containing the pit is 71 km (44 mi) in diameter. Incidence Angle: 66.8° Emission Angle: 0.1° Phase Angle: 66.7° Of Interest: The two largest craters in this image are Burns (43 km in diameter) and To Ngoc Van (71 km in diameter). To Ngoc Van contains an irregularly shaped pit, similar to those seen inside of the craters Beckett, Picasso, and Gibran, among others. This image was acquired as part of MDIS's high-resolution surface morphology base map. The surface morphology base map will cover more than 90% of Mercury's surface with an average resolution of 250 meters/pixel (0.16 miles/pixel or 820 feet/pixel). Images acquired for the surface morphology base map typically have off-vertical Sun angles (i.e., high incidence angles) and visible shadows so as to reveal clearly the topographic form of geologic features.
