In this beautiful VIS image, taken by the NASA - Mars Odyssey Orbiter on June, 3rd, 2004, and during its 10.960th orbit around the Red Planet, we can see the beginning (---> the Source) of the large Outflow Channel known as Ares Vallis, which is located right at the edge of the Martian Region known as Iani Chaos.

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 19778) has been additionally processed, magnified to aid the visibility of the details, extra-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.
