Of Interest: This image taken by MDIS's Wide Angle Camera is dominated by an unnamed basin formed from a large impact on the surface of Mercury. Although the impact was energetic enough to create a central peak ring in the basin, the ring has been mostly flooded by impact melt and/or volcanic plains. To the MESSENGER summer interns, the partial ring of mountains resembles a smile.

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.
