Tour three Martian landscapes and find out how erosion and water affected the surface of Mars, in this video adapted from NASA. Flyover images created from HiRISE (High Resolution Imaging Science Experiment), an instrument on board the Mars Reconnaissance Orbiter, show the structure and composition of the Martian landscape. In Candor Chasma, part of a canyon system, large buttes were likely formed by the process of erosion. Channels running down from terraces may be evidence of rainfall at Mojave crater. False-color images show the presence of minerals in an area called Nili Fossae. Carbonates (shown in green) indicate an environment that could once have been conducive to life. This video is available in both English and Spanish audio, along with corresponding closed captions. This resource is part of the NASA Planetary Sciences Collection.
