“Starburst Spider” was uploaded to Flickr

Mars' seasonal cap of carbon dioxide ice has eroded many beautiful terrains as it sublimates (goes directly from ice to vapor) every spring. In the region where the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter took this image on Feb. 4, 2009, we see troughs that form a starburst pattern. via NASA ift.tt/1SJIc8a
