Of Interest: The low Sun elevation in this scene emphasizes the topography of Van Eyck crater. The rim of Van Eyck has been profoundly cratered by material ejected from the Caloris basin. Smooth plains fill the floor of Van Eyck, but they too have been affected by cratering, from large primary impacts to deep, linear incisions by secondary crater chains.

Jan Van Eyck was a Flemish painter who lived from about 1390 to 1441 CE. The stratigraphic unit comprising the ejecta from the Caloris basin is named the Van Eyck Formation. The Van Eyck Formation is regarded by scientists as equivalent to the Fra Mauro Formation that surrounds the Moon's Imbrium basin. The Van Eyck Formation is characterized by elongated hilly ridges and grooves that are sub-radial to the Caloris Basin, and which are extensively embayed by smooth plains.

This image was acquired as part of MDIS's high-incidence-angle base map. The high-incidence-angle base map complements the surface morphology base map of MESSENGER's primary mission that was acquired under generally more moderate incidence angles. High incidence angles, achieved when the Sun is near the horizon, result in long shadows that accentuate the small-scale topography of geologic features. The high-incidence-angle base map was acquired with an average resolution of 200 meters/pixel.
