Perched Above Gusev Crater

This approximate true-color image taken by the Mars Exploration Rover Spirit shows a rock outcrop dubbed "Longhorn," and behind it, the sweeping plains of Gusev Crater. On the horizon, the rim of Gusev Crater is clearly visible. The view is to the south of the rover's current position. The image consists of four frames taken by the 750-, 530- and 430-nanometer filters of Spirit's panoramic camera on sol 210 (August 5, 2004).
