CAPTION: Snow and ice made up of carbon dioxide (better known as dry ice) cover dunes on Mars. Sun shining on the ice creates cracks, allowing gas to escape and carry dark sand out from the dune below. Image captured 21 May 2017 by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter.
