This image shows the tracks left by NASA's Curiosity rover on Aug. 22, 2012, as it completed its first test drive on Mars. The rover went forward 15 feet (4.5 meters), rotated 120 degrees and then reversed 8.2 feet (2.5 meters). Curiosity is now 20 feet (6 meters) from its landing site, named Bradbury Landing.
This image was taken by a front Hazard-Avoidance camera, which has a fisheye lens.
