In this VIS image, taken by the NASA - Mars Odyssey Orbiter on August, 8th, 2014, and during its 56.122nd orbit around the Red Planet, we can see a large Patch of very Dark (actually, it is almost black - at least in our Absolute Natural Colors interpretation of the picture) Sand, that lies on the Western/South-Western Portion of the Floor of an (unusually-looking) Unnamed Impact Crater located in the very old, heavily cratered, highly eroded and - last, but not least - extremely dusty Martian Region known as Arabia Terra.

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 18698) has been additionally processed, magnified to aid the visibility of the details, contrast enhanced and sharpened, 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.
