In this nice VIS image, taken by the NASA - Mars Odyssey Orbiter on March, 15h, 2008, and during its 27.733rd orbit around the Red Planet, we can see a small portion of the Martian Region known as Acidalia Planitia, a largely Flat Plain that is part of Mars' vast Northern Lowlands. Planetary Scientists are (obviously...) still debating the likelihood that the so-called Northern Plains once contained a large Ocean or, maybe, a few - relatively - big Bodies of Water, probably Ice-covered.

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 19796) has been additionally processed, magnified to aid the visibility of the details, 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.
