In this VIS image, taken by the NASA - Mars Odyssey Orbiter on August, 20th, 2013, and during its 51.824th orbit around the Red Planet, we can see a small portion of the Northern Side of the huge Martian Shield-Volcano known as Olympus Mons. Part of its Summit Caldera, which is almost perfectly circular and characterized by an extremely flat Floor, can be seen at the very bottom of the frame. Also notice the almost complete lack of Impact Craters (actually, we can count less than ten of them, and only one with an easily perceivable size) that can be spotted on the Northern Slopes of the Volcano (a circumstance, this one, which proves beyond doubts that the Slopes of Olympus Mons are - always Geologically, and therefore relatively speaking, in terms of Time - recent.

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 17523) has been additionally processed, magnified, 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.
