This stereo anaglyph looking toward the northeast across "Endurance Crater" in Mars' Meridiani Planum region was assembled from frames taken by the navigation camera on NASA's Mars Exploration Rover Opportunity during the rover's 131st martian day, or sol, on June 6, 2004. That was two sols before Opportunity entered the crater, taking the route nearly straight ahead in this image into the "Karatepe" area of the crater. This view is a cylindrical-perspective projection with geometric seam correction.
