Mars - Mariner 4

Surface of Mars near 48 S, 139 W, poor contrast

Mariner 4 image of Mars near 48 S, 139 W. The lower light levels at this point necessitated high contrast enhancements for this image, which gives it its grainy, layered appearance. Individual features cannot be distinguished. The image was taken from 12,000 km and the frame is 273 x 236 km. The sun is 70 degrees from the zenith and north is at 12:30. (Mariner 4, frame 16D)
