** FILE ** This file image provided by NASA shows the base of Mount Sharp on Mars. The Curiosity rover is set to drive toward the mountain in mid-February after drilling into a rock. The image was taken by Curiosity's 100-millimeter Mast Camera on Aug. 23, 2012. Scientists enhanced the color in one version to show the Martian scene under the lighting conditions we have on Earth, which helps in analyzing the terrain. (AP Photo/NASA/JPL-Caltech/MSSS, File)
