In this VIS image, taken by the NASA - Mars Odyssey Orbiter on March, 5th, 2014, and during its 54.223rd orbit around the Red Planet, shows us another Unnamed Impact Crater located near the North Pole of Mars, and with a small Dark Sand Dunefield on its Floor and Residual Water-Ice Frost - very well visible here - on its Inner North/Western and Outer South/Eastern Rim.

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 18252) 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.
