Mars Dust Devils

DUST DEVILS LEAVE THEIR MARK: Dark swirls made by Martian winds make intricate patterns on sand dunes in this image taken with the High Resolution Imaging Science Experiment (HiRISE) camera aboard NASA’s Mars Reconnaissance Orbiter (MRO) mission. Just as it does on Earth, the wind helps to shape the Martian surface. As strong winds blow across the Martian landscape, they generate and propel dust devils, which produce temporary dark scars across the lighter sand dunes. This image shows an area of roughly 1km of the Martian surface. Image Credit: NASA/JPL/University of Arizona
