NASA's Mars Exploration Rover Spirit took this left eye of a pair of stereo images, projected at a cylindrical perspective, with its navigation camera on sol 156 (June 11, 2004). The image highlights Spirit's arrival at the base of the Columbia Hills. Since landing at Gusev crater, Spirit has put more than 3.4 kilometers (2.1 miles) on its odometer. Much of this can be attributed to the long drives the rover had to undertake to reach these interesting landforms.
See PIA06280 for 3-D view and PIA06282 for right eye view of this left eye cylindrical-perspective projection.
