Mars - Mariner 4

Low contrast image of the surface of Mars at 51 S, 122 W

No features can be distinguished in this Mariner 4 image of Mars because the sun was 80 degrees from zenith and light levels were too low. The extreme contrast enhancement used on this frame gives the blocky layered appearance. The image is 308 km by 242 km and was taken from 12,000 km. North is at 1:00. (Mariner 4, frame 18e)
