NASA Mars Reconnaissance Orbiter HiRISE Images April 25, 2012

– How Did Valles Marineris Form?

The opening of Valles Marineris did involve crustal spreading and faulting, but may have had a more complex history.

– Folded Layers in Melas Chasma, Central Valles Marineris

How did this folding occur? On Earth, rocks are commonly folded when deeply buried and subject to high heat and pressure, which can make any rock flow.

– Sedimentary Layers in West Candor Chasma

West Candor Chasma in central Valles Marineris contains some of the thickest of the fine-grained layered deposits on Mars.

– Terrain Near the MSL Landing Site

This image is of a region slightly to the southwest of where the MSL rover, called Curiosity, will land in August 2012.
