In this beautiful VIS image, taken by the NASA - Mars Odyssey Orbiter on March, 3rd, 2016, and during its 63.074th orbit around the Red Planet, we can see - once again - a small portion of the Martian Region known as Olympia Undae. As a matter of fact, Olympia Undae is the largest Dunefield located at the Margin of the North Polar Cap of Mars. This fantastic frame (which, by the way, is an Extra Detail Magnification -"EDM" - of the Original Frame) was collected by the NASA - Mars Odyssey Orbiter during the Northern Hemisphere's Summer. Some Snow and Water Ice, howerer, and as you can see, are still there...

This image (which is a crop obtained from an Original Mars Odyssey Orbiter b/w and Map Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 20615) 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.
