Cracked Mars

August 14, 2013
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows v-shaped troughs in the Hephaestus Fossae region of Mars. Light-toned, windblown ripples reside in the very lowest parts of the troughs, as well as on the cratered upland outside the troughs. Boulders and other types of debris, which were derived from the layered rock exposed near the top of the troughs, are seen resting on the trough floors and perched on the sloping trough walls. MGS MOC Release No. MOC2-1504, 25 June 2006
