Title:[0045] Close-up of DeimosCaption:The Viking 2 Orbiter was maneuvered to within 30 km of Deimos to take this high resolution image in which features as small as 3 meters across can be discerned. Many craters are filled with dust and appear only as ghostly outlines. Boulders 10 to 30 meters across are strewn over the surface.
