Of Interest: Can you see the face in this image? The two large craters towards the upper corners of this picture make eyes, and the prominent central peak is a perfect nose. It seems our model wasn't prepared for his MDIS photo shoot, as apparent from the perfect "O" mouth. This unnamed land form is part of a large, heavily cratered area in Mercury's northern hemisphere.

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.

The MESSENGER spacecraft is the first ever to orbit the planet Mercury, and the spacecraft's seven scientific instruments and radio science investigation are unraveling the history and evolution of the Solar System's innermost planet. During the first two years of orbital operations, MESSENGER acquired over 150,000 images and extensive other data sets. MESSENGER is capable of continuing orbital operations until early 2015.
