A portion of Mount Sharp, on Mars is pictured in this panorama made from a mosaic of images taken by the Mast Camera (Mastcam) on NASA's Mars rover Curiosity September 20, 2012 and released as a NASA handout image March 15, 2013. The photo has a white-balanced color adjustment that makes the sky look overly blue but shows the terrain as if under Earth-like lighting.
