Mazamba Crater (a medium-sized Martian Impact Crater whose diameter is of approx. 52 Km - such as about 32,29 miles) is one of the 4 (four) Martian Impact Craters that are known (of course, at present time) to possess some (almost) intact Layers which are exposed in their Central Uplifts. Planetary Scientists believe that this Layered Material (very well visible here, in today's APOD) originates (---> comes) from a few kilometers beneath the present (---> as it is seen today) Martian Surface and that it was somehow raised-up during the formation of the Crater itself. These kind of Impact Craters, in fact, give us a window of visibility (and understanding) into these deep Layers, which would have otherwise remained hidden in the depths of the Red Planet.

This picture (which is a NASA - Original Mars Reconnaissance Orbiter False Colors and NON-Map Projected Sub-frame identified by the serial n. ESP_033248_1520) has been additionally processed, magnified, contrast enhanced, Gamma corrected, and then re-colorized in Absolute Natural Colors (such as the colors that a human eye would actually perceive if someone were onboard the NASA - Mars Reconnaissance 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.
