Dunes on Mars

dunes

This isn’t a new picture, but I hadn’t seen it before a friend put in on their Facebook page at the weekend. It isn’t what I first thought it was – a wonderful piece of abstract art – but is, in fact, an equally wonderful photograph of the inside of the Bunge crater on Mars, where a complex pattern of dunes has formed through wind action. The area covered by the image is about 14 kilometers wide.

According to the official NASA webpage: “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.”
