Mars Reconnaissance Orbiter

The Mars Reconnaissance Orbiter's main instrument is a telescopic camera, which will map parts of the Martian surface with unprecedented clarity. Scientists will use the pictures to plot the landing sites for future robotic and manned missions.The pictures and other observations also are providing new data in the search for water on Mars. The observations have helped locate minerals that formed in a watery environment. MRO also carries a radar system that discovered deposits of frozen water below the surface.
