This is a false-color composite image of Valles Marineris, Planet Mars' very own Grand Canyon, captured by the High Resolution Stereo Camera (HRSC) aboard ESA's Mars Express spacecraft. Stretching across the Martian highlands for 2,485 miles (4,000 kilometers) in length, 124 miles wide and up to 6.8 miles deep, Valles Marineris is considered one of the largest known canyon systems in the solar system.

Space Shot of the Day is a feature series following the latest developments in planetary science, astrophotography, space exploration, future plans for colonization and all things related to outer space.
