View into a crater with dark dunes in the Aonia Terra region
The images were taken by the HRSC (High Resolution Stereo Camera) on 16 May 2017 during Mars Express orbit number 16934. The image resolution is 13 metres per pixel. An expansive field of dark dunes is located inside the large crater on the left of the image. The shape of the field is indicative of a prevailing wind direction from the south-east (approximately bottom left). Material from previous volcanic activity gives the dunes their typical dark colour. Just over a dozen barchans or crescent-shaped dunes are found in the smaller crater directly adjacent.
