NASA Mars Reconnaissance Orbiter  HiRISE Images – October 19, 2011

– Mysterious Color-Changing Dust Devil Track

Suction created by the air rotating in a whirlwind removes a thin layer of light-colored dust from the Martian surface, leaving behind dark lines in its path.

– Possible Newest Segment of Cerberus Fossae

Floods of water and lava are thought to have emanated from the larger fossae nearby, perhaps forming the Athabasca channel and later filling it with lava.

– The Millipedes of Mars?

Dunes are particularly suited to comprehensive planetary studies because they are abundant over a wide range of elevations and terrain types.

– Lobate Flow Features in the Northwest Hellas Rim

Lobate features such as these are indicative of viscous flow, reminiscent of terrestrial glaciers and have long-been interpreted as evidence for subsurface ice.
