Valles Marineris

(val -eez ma-ră-nair -iss) A vast system of canyons on Mars photographed by Mariner 9. The canyons had long been recognized as a feature of the Martian surface, subject to changes in brightness, and known collectively as Coprates canyon. They were renamed Valles Marineris in commemoration of the Mariner project. The Valles Marineris are located near the Martian equator and centered on the coordinates 14° S latitude and 59° W longitude (see areography). See Mars, surface features.
