This 360-degree panorama shows evidence of a successful first test drive for NASA's Curiosity rover. A small 3.5-inch (9 centimeters) rock can be seen where the drive began, which engineers say was partially under one of the rear wheels. Scour marks left by the rover's descent stage during landing can be seen to the left and right of the wheel tracks. The lower slopes of Mount Sharp are visible at the top of the picture, near the center.
