In this simply beautiful VIS image, taken by the NASA - Mars Odyssey Orbiter on January, 30th, 2016, and during its 62.680th orbit around the Red Planet, we can see a so-called "Sand Sheet" with Surface Dune Forms (probably a "Migrating Dunefield") that is visible on the Floor of an Unnamed Impact Crater located in the Martian Region known as Vastitas Borealis. Please notice the Residual Water Ice on the Northern Upper Rim as well as on the North-facing Inner Slopes of the aforementioned Crater.

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 20452) has been additionally processed, magnified to aid the visibility of the details, extra-contrast enhanced and sharpened, Gamma corrected and then 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.
