This image from the front hazard-avoidance camera (Hazcam) on the NASA Mars Exploration Rover Opportunity shows the rover's arm extended for examination of a target called "Onaping" at the base of an outcrop called "Copper Cliff" in the Matijevic Hill area of the west rim of Endeavour Crater.
The image was taken during the 3,163rd Martian day, or sol, of Opportunity's work on Mars (Dec. 16, 2012).
