It was just a week ago NASA's Mars rover Curiosity landed on the surface of Mars, and began transmitting high-resolution images of the stunning landscape from the landing site inside the Gale Crater. New color mosaics from the Mastcam show the geological environment around the rover, including layers of cobbles and pebbles embedded in a finer matrix of material, as well as a network of fluvial valleys believed to have been formed by water erosion.
