This is the left-eye half of a stereo pair of 360-degree views assembled from frames taken by the navigation camera on NASA's Mars Exploration Rover Spirit during Spirit's 151st martian day, or sol, on Junr 5, 2004. The view is presented in a cylindrical-perspective projection with geometric seam correction. The rover sits at site 63, still more than 100 meters (328 feet) from the base of the "Columbia Hills." As suggested by the rover tracks fading off in the distance, Spirit made great progress on this sol, roving 73 meters (240 feet) to get to this point.
See PIA06053 for 3-D view and PIA06055 for right eye view of this left eye cylindrical-perspective projection.
