In this very interesting VIS image, taken by the NASA - Mars Odyssey Orbiter on March, 27th, 2004, and during its 10.125th orbit around the Red Planet, we can see a small portion of the dark Floor and the highly uneven, eroded and also collapsed, in several points, Rim of an extremely ancient Unnamed Impact Crater located in the Martian Region known as Noachis Terra.

Noachis Terra (litterally, in Latin Language, the "Land of Noah") is an extensive (---> large) Southern Landmass (---> Terra) of the Red Planet. It lies to the West of the giant Hellas Impact Basin, and it is centered at approx. 45° South Latitude and 350° East Longitude, in the Noachis Quadrangle of Mars.

Latitude (centered): 32,8453° South
Longitude (centered): 333,6190° East
Instrument: VIS

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 19754) 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.
