Bunge Crater Dunes

Fans and ribbons of dark sand dunes creep across the floor of Bunge Crater in response to winds blowing from the direction at the top of the picture. The frame is about 14 kilometers (9 miles) wide.

This image was taken in January 2006 by the Thermal Emission Imaging System instrument on NASA's Mars Odyssey orbiter and posted in a special December 2010 set marking the occasion of Odyssey becoming the longest-working Mars spacecraft in history. The pictured location on Mars is 33.8 degrees south latitude, 311.4 degrees east longitude.

Note: Bunge Crater is located in the far western region of Noachis Terra, slightly to the northwest of Argyre Planitia.
