Valles Marineris stretches over 4,000 km (2,500 mi) across Mars, mostly east-west just below the equator, as seen in this Viking 1 orbiter image mosaic.

Jul 28, 2022 · Mars is smaller than Earth (about half Earth’s size). But its vast canyon system called Valles Marineris dwarfs even our earthly Grand Canyon. Orbiting spacecraft have imaged it many times....

Mar 23, 2008 · The largest canyon in the Solar System cuts a wide swath across the face of Mars. Named Valles Marineris, the grand valley extends over 3,000 kilometers long, spans as much as 600 kilometers across, and delves as much as 8 kilometers deep.

Oct 22, 2018 · The Valles Marineris is a system of canyons located just south of the Martian equator. The system is about 4000 km long, and, if on earth, would extend all the way across the United States. The central individual troughs, generally 50 to 100 km wide, merge into a depression as much as 600 km wide.

Jul 9, 2013 · The center of the scene shows the entire Valles Marineris canyon system, more than 2,000 miles (3,000 kilometers) long, 370 miles (600 kilometers) wide and 5 miles (8 kilometers) deep, extending from Noctis Labyrinthus, the arcuate system of graben to the west, to the chaotic terrain to the east.

Dec 16, 2021 · The ESA-Roscosmos ExoMars Trace Gas Orbiter has spotted significant amounts of water at the heart of Mars’ dramatic canyon system, Valles Marineris.
