In this VIS image, taken by the NASA - Mars Odyssey Orbiter on July, 21st, 2003, and during its 7.099th orbit around the Red Planet, we can see a portion of the relatively flat Floor - including a small section of the Southern Inner Rim as well as an highly degraded Central Peak - of an ancient Unnamed Imapct Crater located in the Southern Martian Region known as Terra Cimmeria.

Terra Cimmeria is a large Martian Region, centered at 3442 South Latitude and 14500 East Longitude; it covers approx. 5.400 Km (such as about 3353,4 miles) at its broadest extent. Terra Cimmeria expands from the Latitudes 15 North uo to 75 South and the Longitudes going from 170 up to 260 West; it lies in the Eridania Quadrangle of Mars.

Just out of curiosity, Terra Cimmeria is one part of the heavily Cratered, Southern Highland Regions of the Red Planet.

This image (which is an Original Mars Odyssey Orbiter falsely colored and Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 19431) has been additionally processed, magnified to aid the visibility of the details, contrast enhanced and sharpened, Gamma corrected and then re-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.
