Valles Marineris is a system of canyons that spans 2,500 miles (4,000 kilometers). It is so deep that a spacecraft flying an aggressive landing profile into the canyon would do the hypersonic phase of atmospheric entry (the part with the fire and the heat shield) below the rim of the canyon so that an observer would be able to look down into the canyon from the rim to see the meteor-like spacecraft streaking through the sky. At some points, the canyon is 125 miles (200 km) wide. A view of the East Central Troughs of the Valles Marineris taken by Viking I orbiter on October 1, 1976. Scientists do not yet know whether the flooding took place over a short span of time, or whether one overwhelming flood was accompanied by several smaller flooding events. The largest canyon on Mars: Valles Marineris or “The Grand Canyon of Mars.” This is the largest canyon in the solar system; extending over 3000 km (1864 mi) in length and spanning as much as 600 km (372.8 mi) across.

Students need a background in basic rock classification in order to be successful in this exercise as well as … And it is interesting to compare Mars' canyon with ours. (Hint: Basin and Range Province of the United States). "Jarosite is usually considered an evaporative mineral: it forms from acidic water that is evaporating," lead author Selby Cull, of Bryn Mawr College in Pennsylvania, told Space.com. There was a problem. "This reinforces our assumption that we are looking at magmatic rock volcanism and not liquid mud.". 1. "Getting an evaporating pool of water halfway up a 3-mile-high cliff is tricky, and the more we looked into the geologic context surrounding the deposit, the less likely a liquid water origin seemed.". 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. In contrast to the Grand Canyon, which formed by erosion, the Valles Marineris formed mainly by faulting, although they have been enlarged by erosion.

Today, most scientists think that the formation of the Tharsis region may have helped the canyon to form. Also it contains canyons that run in different directions surrounding large blocks of older terrain. It starts in the west in the Noctis Labyrinthus, a system of maze-like valleys and canyons, and stretches around 20 percent of the planet to the chaotic terrain near the Chryse Planitia basin. Signs of flooding are especially apparent at the eastern end, in the mesas and hills known as chaotic terrain. Named after the Mariner 9 Mars orbiter of 1971/1972, Valles Marineris is one of the largest systems of canyons in the solar system. And if you have a news tip, correction or comment, let us know at: community@space.com. The Grand Canyon is about 450 kilometers (280 miles) long, while this tributary is only 140 kilometers (72 miles) long.
