In this VIS image, taken by the NASA - Mars Odyssey Orbiter on February, 7th, 2015 and during its 58.336th orbit around the Red Planet, we can see a portion of a large Sand-Sheet with Surface Dune-Forms (---> probably a so-called - and extremely dark - "Migrating Dunefield") that is found on the Floor of an Unnamed Impact Crater located in the Martian Region known as Noachis Terra.

This frame (which is an Original Mars Odyssey Orbiter b/w and Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 19275) has been additionally processed, magnified, contrast enhanced 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.
