Photo: The Serpent Dust Devil of Mars
Posted on March 7, 2012
The High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter captured this image of a huge dust devil on Mars. The dust devil casts a serpentine shadow over the Martian surface. NASA says the length of the dust devil's shadow indicates the dust plume reaches over 800 meters (over half a mile) in height. The image was taken in the Amazonis Planitia region of northern Mars. You can see an extra large image of the serpentine dust devil here.
