In this suggestive VIS image, taken by the NASA - Mars Odyssey Orbiter on April, 11th, 2015, and during its 59.110th orbit around the Red Planet, we can see a small portion of the Floor of an Unnamed Impact Crater located in the Martian Region known as Noachis Terra. The Floor, as you can see very well here, contains an orange-colored Sand Sheet, with an interesting (and extremely dark) Dune-Form.

This image (which is an Original Mars Odyssey Orbiter b/w and Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 19478) has been additionally processed, magnified to aid the visibility of the details, contrast enhanced and sharpened, Gamma corrected and then re-colorized in Absolute Natural Colors (such as the colors that a normal 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.
