Today's Image of Mars comes from HiRISE and shows an uplifted jumble of ancient terrain in a crater located in the volcanic plains between Argyre Basin and Valles Marineris. Large craters often have central mounds that result from structural uplift and reveal material buried deep under the surface over the course of millions and sometimes billions of years.
Examining these central mounds allows scientists to determine the past environment on Mars by examining the composition of the layered deposits making up the mound. This is exactly what Mars Science Laboratory, Curiosity will be doing when it lands in Gale Crater this August.
