Impact Crater Intersection


This high-resolution image shows the intersection of two crater rims. The full craters can be seen in this context image -- the high-resolution image covers the rim intersection very close to the context image center. Downslope movement of material in the crater wall has exposed fresh, brighter soil.

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.
