In this really inspiring VIS image, taken by the NASA - Mars Odyssey Orbiter on July, 9th, 2002, and during its 2.510th orbit around the Red Planet, we can see a relatively small portion of the Floor of the huge Martian Outflow Channel (carved by fluids, perhaps even water - but nobody can be sure about this circumstance so far) known as Ares Vallis, with several "Insulae" (a Latin word for "Islands") in it.


Also - of course, always relatively speaking -, a small and fresh Impact Craters' Cluster can be seen in the central portion of the frame, towards the Left (Sx).

This image (which is an Original Mars Odyssey Orbiter false colors and Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 18999) 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.
