A stunning HiRISE image reveals the defrosting of Mars' south polar CO2 ice cap. Circular pits, approximately 60 meters across, are formed as the dry ice sublimates into gas, leaving behind intriguing, gold-rimmed features. The image shows the unique textures and patterns created by this seasonal process on the Martian surface.
