Image Mission Elapsed Time (MET): 28935228 Image ID: 5350994 Instrument: Wide Angle Camera (WAC) of the Mercury Dual Imaging System (MDIS) WAC filter: 7 (748 nanometers) Center Latitude: 60.08° Center Longitude: 223.9° E Resolution: 166 meters/pixel Scale: Kosho crater is ~65 km (40 mi.) in diameter. Incidence Angle: 91.6° Emission Angle: 50.4° Phase Angle: 142.0°

Of Interest: This image crosses the terminator, the transition between day and night. An observer located on Kosho's illuminated central peak at the time this image was taken would see the sun setting over the horizon.

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.
