Valles Marineris
Valles Marineris (Latin for "Mariner Valleys", named after the "Mariner 9" Mars orbiter of 1971–72 which discovered it) is a system of canyons that runs along the Martian surface east of the Tharsis region. At more than long, wide and up to deep, Valles Marineris is one of the largest canyons of the Solar System, surpassed in length only by the rift valleys of Earth.
Valles Marineris is located along the equator of Mars, on the east side of the Tharsis Bulge,
States. The name for the whole system of canyons is Valles Marineris. Starting at the west with Noctis Labyrinthus in the Phoenicis Lacus quadrangle, the canyon system ends in the Margaritifer Sinus quadrangle with Capri Chasma and Eos Chasma (in the south). The word Chasma has been designated by the International Astronomical Union to refer to an elongate, steep-sided depression. Valles Marineris was discovered by and named for the Mariner 9 mission. Moving east from Noctis Labyrinthus, the canyon splits into two troughs, Tithonium Chasma and Ius
