Valles Marineris is currently the largest known canyon in the Solar System and it cuts a wide swath across the face of Mars. This grand valley extends over 3,000 kilometers long, spans as much as 600 kilometers across, and delves as much as 8 kilometers deep. For comparison, the Grand Canyon in Arizona spans 800 kilometers long, 30 kilometers across, and 1.8 kilometers deep. It is unknown how Valles Marineris formed, although a leading hypothesis holds that it started as a crack billions of years ago as the planet cooled.

HiRise (High Resolution Imaging Science Experiment) is a camera mounted on the Mars Reconnaissance Orbiter, which has been studying the Red Planet since 2006. Weighing 143-pounds, this instrument was built under the direction of the University of Arizona’s Lunar and Planetary Laboratory by Ball Aerospace & Technologies Corp. It consists of a 0.5 m (19.7 in) aperture reflecting telescope, the largest yet of any deep space mission, thus enabling it to take pictures of Mars with resolutions of 0.3 m/pixel (about 1 foot).
