Planet Mars and the Valles Marineris Canyon

A mosaic image of the planet Mars with the Valles Marineris Canyon front and center. Valles Marineris is about 3000 kilometers (2000 miles) long and about 500 kilometers wide at its widest point. Valles Marineris may have been formed by flowing water during the early history of Mars.
