In this VIS image, taken by the NASA - Mars Odyssey Orbiter on July 2nd, 2013, and during its 51.232nd orbit around the Red Planet, we can see a relatively large, dark and, probably, "Migrating" Dunefield that is found on the Floor of an old and Unnamed Impact Crater located in the Martian Southern Region known as Noachis Terra.

Even this Dunefield (just like the one found on the Floor of Proctor Crater - please, refer to yesterday's APOD if you want to know more -, as well as many others, located on both Martian Hemispheres) is being monitored by several Spacecrafts now orbiting the Red Planet (including the NASA- Mars Reconnaissance Orbiter) with the aim of identifying the movements (---> shifting, if any) of the Dunefield and the changes (again, if any) which might have occurred - over time - in the shape of the Dunefield itself.

This frame (taken from an Original Mars Odyssey Orbiter b/w and Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 17420) has been additionally processed, magnified, contrast enhanced, Gamma corrected and then colorized in Absolute Natural Colors (such as the colors that a human eye would actually perceive if someone were onboard the NASA - Mars Odyssey Orbiter and then looked down, towards the Surface of Mars), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.
