High-resolution view of Mars's moon Deimos from 30 km

This is one of the highest-resolution images ever taken from an orbiting or flyby spacecraft. This Viking 2 orbiter image shows the surface of Mars's moon Deimos from a distance of 30 km. The image covers an area of 1.2 km by 1.5 km and features as small as 3 meters across can be seen. Note that many of the craters are covered over by a layer of regolith estimated to be about 50 meters thick. Large blocks, 10 to 30 meters across, are also visible. North is at 11:30.
