About this work
This image from NASA's Mars Reconnaissance Orbiter (MRO) shows the permanent polar cap of Mars, encircled by sand dunes and looking like pulled threads, these dunes march across a fabric of patterned ground. At this time of the Martian year the dunes are free of the seasonal dry ice that forms a temporary cover every winter.
