Using the high-resolution camera, HiRISE, on the Mars Reconnaissance Orbiter (MRO) spacecraft, visual clues such as peaks and craters seen in earlier images, and old-fashioned detective skills, scientists were able to identify the landing site for the 1997 Pathfinder mission's rover Sojourner within a vast landscape of seemingly homogenous Martian terrain.
