In this VIS image, taken by the NASA - Mars Odyssey Orbiter on June, 26, 2013, and during its 51.158th orbit around the Red Planet, we can see some large Depressions (Collapse Pits, perhaps) and a few thin and long Channels (whose origin and nature is still unknown) which characterize the Surface Material (Dust covered and, probably, extremely yielding) that fills the Floor of Asimov Crater (another ancient Impact Crater located, just like Rabe Crater, in the Noachis Quadrangle at 47,00° South Latitude and 355,05° West Longitude). Asimov Crater is about 84 Km - such as about 52,164 miles - in diameter and it was so named after the American Biochemist and Writer Isaac Asimov (1920 – 1992).

This frame (which is an Original Mars Odyssey Orbiter b/w frame published on the NASA - Planetary Photojournal with the ID n. PIA 17346) 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.
