NASA's Mars Exploration Rover Opportunity used its panoramic camera to record this eastward horizon view on the 2,407th Martian day, or sol, of the rover's work on Mars (October 31, 2010). The view is presented in false color to make differences in surface materials more visible. A portion of Endeavour Crater's eastern rim, nearly 30 kilometers (19 miles) in the distance, is visible over the Meridiani Planum.
