This image taken by NASA's Curiosity shows what lies ahead for the rover -- its main science target, informally called Mount Sharp. The rover's shadow can be seen in the foreground, and the dark bands beyond are dunes. Rising up in the distance is the highest peak of Mount Sharp at a height of about 3.4 miles (5.5 kilometers), taller than Mt. Whitney in California. The Curiosity team hopes to drive the rover to the mountain to investigate its lower layers, which scientists think hold clues to past environmental change. This image was captured by the rover's front left Hazard-Avoidance camera at full resolution shortly after it landed. It has not yet been linearized to remove the distorted appearance that results from its fisheye lens.
