Mars - Mariner 4

Poor contrast view of the surface of Mars at 50 S, 130 W

Mariner 4 image taken slightly before the spacecraft passed the terminator to the unlit portion of the planet. The sun was 76 degrees from zenith and light levels were low. High contrast enhancement applied to the image resulted in the layered appearance. The image was taken from 12,000 km and covers 292 km by 238 km. North is at 1:00. (Mariner 4, frame 17e)
