That’s from the navigation camera on the Mars rover Opportunity, picture series Sol 1850. The entire library of raw images from both Spirit and Opportunity is simply amazing… All told, that’s 234,780 pictures and counting from a five year mission designed to last only three months. (So far, the rovers have suffered a broken robotic arm, computer resets, and a stuck wheel. Still, they keep keeping on.)
Anyway… Ansel Adams, eat your heart out.
