Ghost Crater Near Suisei Planitia

This image features a ghost crater ~55 km (34 mi.) in diameter near its center. The crater was likely flooded by the lava that formed the Suisei Planitia. The crater rim and central peaks can still be seen, despite their burial, and the area was showered by secondary craters from a subsequent impact event.

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.
