A new study from ETH Zurich geoscientists Giovanni Leone, however, suggests that lava, rather than water or tectonic plate activity, cut the gigantic valleys into the red planet's landscape.
Two distinct volcanic eruptions have flooded this area of Daedalia Planum with lava, flowing around an elevated fragment of ancient terrain.
Ripped apart by tectonic forces, Hebes Chasma and its neighboring network of canyons bear the scars of the Red Planet’s early history.
Glide through part of the largest canyon on Mars, Valles Marineris, in this stunning color movie from ESA's Mars Express.
The European Space Agency (ESA) said that a new image taken by its Mars Express orbiter shows off flood events that took place on the Red Planet.
Valles Marineris stretches over 4000 kilometers in length and is 200 kilometers wide, with a maximum depth of 10 kilometers. This makes it 10 times longer and five times deeper than the Grand Canyon, earning it the title of the largest canyon in the Solar System.
Mars Express has helped to unveil volcanic history of the Red Planet, providing more insight as to what lies underneath our celestial neighbor.
Flowing lava can carve or build paths very much like the riverbeds and canyons etched by water, and this probably explains at least one of the meandering channels on the surface of Mars.
The Mars Express High Resolution Stereo Camera imaged a region close to Maâ€™adim Vallis, one of the largest canyons on Mars, finding craters, lava flows and tectonic features.
CU-Boulder Study Provides Possible Explanation for Migration of Volcanic Activity on Mars
Olympus Mons -- Olympus Mons is the tallest mountain in the solar system, at 25 km. Located on Mars, and officially called by its Latin name Olympus Mons. It is named for the mountain on Earth. Olympus Mons is an apparently extinct shield volcano, the result of highly fluid magma flowing out of volcanic vents over a long period of time, and is much wider than it is tall; the average slope of Olympus Mons' flanks is very gradual. The Hawaiian islands are an example of similar shield...
