In this nice VIS image, which is a crop obtained from a picture taken by the NASA - Mars Odyssey Orbiter on January, 27th, 2015, and during its 58.206th orbit around the Red Planet, we can see a small section (actually, the Southern one, to be precise) of the unique Asimov Crater. Why "unique"? Because the Crater's Floor has been completely filled with (rocky and sandy) Material to approximately the Rim of it; furthermore, a series of deep and steep Collapse-like Surface Depressions (we can see one here) have occurred near the Southern Portion of the Crater's Rim itself. Their origin, is still unknown.

Asimov Crater is an Impact Crater located in the Noachis Quadrangle of Mars, and centered at 47,0° South Latitude and 355,05° West Longitude. It is about 84 Km (such as approx. 52,164 miles) in diameter and it was so named after the famous Isaac Asimov (1920 – 1992), an American biochemist and talented writer.

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 19258) has been additionally processed, magnified to aid the visibility of the details, 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.
