In this highly suggestive VIS image, taken by the NASA - Mars Odyssey Orbiter on June, 2nd, 2010, and during its 37.552nd orbit around the Red Planet, we can see a truly small portion of the peri-Equatorial Martian Region known as Margaritifer Terra. The dark gray (actually, almost black, here and there) color visible in the lower central portion of the picture indicates, just like in yesterday's APOD, the presence of Surface Features containing, covered by and/or made of large amounts of Volcanic Sands and/or other Basaltic Materials.

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 20767) 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.
