In this VIS image, taken by the NASA - Mars Odyssey Orbiter on September, 4th, 2014, and during its 56.451st orbit around the Red Planet, we can see, located on the Floor of a larger Unnamed Impact Crater, another (relatively) small Impact Crater which has numerous fresh and well defined Gullies all around its Inner Rim as well as an unusually-lookintg, complex and elongated, Central Uplift.

This Impact Crater is located in the Martian Region known as Terra Cimmeria (as we wrote in yesterday's APOD, a large Region, centered at 34° 42' South Latitude and 145° 00' East Longitude, and covering approx. 5.400 Km - such as about 3353,4 miles - at its broadest extent). Terra Cimmeria, as you know, is just one portion of the ancient and extremely heavily cratered Southern Highlands of Mars. Just out of curiosity, this Impact Crater seems to show a degraded, thin and oblong in shape "Pedestal" around it.

Latitude (centered): 38,1315° South

This image (which is a crop taken out of an Original Mars Odyssey Orbiter b/w and Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 18720) has been additionally processed, magnified to aid the visibility of the details, contrast enhanced and sharpened, Gamma corrected and then colorized in slightly enhanced Absolute Natural Colors (such as the colors that a very sharp 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.
