In this really clear and fascinating VIS image, obtained by the NASA - Mars Odyssey Orbiter on May, 7th, 2006, and during its 19.495th orbit around the Red Planet, we can see a (relatively) small portion of an Unnamed Impact Crater located on the Floor of the much bigger (and famous) Schiaparelli Crater. The gray Material visible in this frame is, most likely, Basaltic Sand.

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 20244) 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.
