View Full Version : Discussion: Collapsed Canyons on Mars

2004-Nov-17, 07:36 PM
SUMMARY: The European Space Agency's Mars Express spacecraft took this photograph of a series of canyon systems on the surface of the Red Planet. The canyons are part of the Coprates Catena, which are at the southern end of the enormous Valles Marineris rift. Sections of the structures appear to have collapsed in on themselves at various points; a few landslides are visible. Scientists theorize that underlying ice or water was removed, which then caused the rock and soil to collapse.
