Impact Crater on the Edge of Oskison Crater


This image features a crater situated at the edge of the larger Oskison crater located in the plains north of Caloris basin. Due to MESSENGER's highly elliptical orbit, MDIS's Wide Angle Camera is capable of capturing higher resolution images in Mercury's northern hemisphere, such as this 58 meters per pixel view. A detailed look at the crater reveals its terraced walls, smooth floor, and its superposition on Oskison's shadowed rim.
