Mars Surface near Viking Lander 1 Footpad
Jet Propulsion Laboratory https://www.jpl.nasa.gov/ May 30, 2008
This image, which has been flipped horizontally, was taken by Viking Lander 1 on August 1, 1976, 12 sols after landing. Much like images that have returned from Phoenix, the soil beneath Viking 1 has been exposed due to exhaust from thruster engines during descent. This is visible to the right of the struts of Viking's surface-sampler arm housing, seen on the left.
