| Get ready to explore the largest canyon system in the solar system. Mars' Valles Marineris — Mariner Valley — comprises several parallel, connecting troughs. It extends east-west about 2,000 miles (3,000 kilometers), spans 420 miles across (700 km), and digs more than 26,000 feet (8,000 meters) deep. It puts the "grand" in grand canyon — Valles Marineris stretches some 7 times longer, 40 times wider, and 4 times deeper than Earth's Grand Canyon. |
