In this very clean and clear VIS image, taken by the NASA - Mars Odyssey Orbiter on December, 30th, 2015, and during its 62.294th orbit around the Red Planet, we can see an Unnamed Impact Crater located to the North/West of the huge Martian Volcano known as Elysium Mons. This Unnamed Impact Crater contains, as you can see, a Central Pit, which formed - most likely - at the time when the Impact occurred.

As a matter of fact, the depth, diameter and central morphology of an Impact Ccrater whatsoever, can provide us with useful information about both the Impactor as well as the pre-existing conditions of the impacted Surface.

This image (which is an Original Mars Odyssey Orbiter b/w and Map Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 20418) has been additionally processed, magnified to aid the visibility of the details, extra-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.
