The main objective for this mission is to map the planet to gain a better understanding of the mineral makeup, and as usual, to determine if it is possible that life ever existed on Mars. Overall, it's a pretty interesting read. The article goes into a little detail about the instruments that will be used in the mapping of the Martian surface."
