Deimos - Viking 2 Orbiter

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

Deimos
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' moon Deimos from a distance of 30 km. The image covers an area 1.2 km by 1.5 km and features as small as 3 meters across can be seen. Note 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. (Viking Orbiter 423B63)
