In this VIS image, taken by the NASA - Mars Odyssey Orbiter on February, 27th, 2014, and during its 54.150th orbit around the Red Planet, we can see a small portion of a Martian Region known as Aspledon Undae: one of the several large Dunefields located near the North Pole of Mars. The term Undae, as you can easily understand, comes from the Latin word "Unda" (---> Wave; plural Undae ---> Waves) and, in this specific case, as the image suggests quite clearly, means Dunes (better yet: Wave-shaped Dunes).

This image (which is a crop taken from an Original Mars Odyssey Orbiter b/w and Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 18237) has been additionally processed, magnified to aid the visibility of the details, contrast enhanced, 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.
