In this slightly fuzzy and - quite obviously - overexposed (but still interesting) VIS image, taken by the NASA - Mars Odyssey Orbiter on December, 28th, 2015, and during its 62.274th orbit around the Red Planet, we can see a small Complex and Unnamed Impact Crater located on the Floor of a larger - and still - Unnamed Impact Crater. Sinuous and dark Sand Dunes are visible on the Floors of the two Craters.


These Unnamed Impact Craters are both located in the 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 20415) 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.
