Deimos Crosses Face of Sun

This image shows the passing, or transit, of the martian moon Deimos over the Sun. This event is similar to solar eclipses seen from Earth in which our Moon crosses in front of the Sun. The image was taken by the Mars Exploration Rover Opportunity on sol 39 of its mission. Deimos passed slightly closer to the center of the Sun than expected, and arrived about 30 seconds early. This observation will help refine our knowledge of the orbit and position of Deimos.
