In this beautiful VIS image, taken by the NASA - Mars Odyssey Orbiter on September, 6th, 2002, and during its 3.233rd orbit around the Red Planet, we can see a very small section of the Floor of the fascinating Pollack Crater. Pollack Crater is an Impact Crater found in the Sinus Sabaeus Quadrangle of Mars and, to be precise, is located (---> centered) at 7,9° Soth Latitude and 334,8° West Longitude. Pollack Crater is approx. 96 Km (such as about 59,616 miles) in diameter and it was so named after James B. Pollack, an American Astrophysicist (born on July, 9, 1938 and died on June, 1994).
Pollack Crater contains - as you can well see in this frame - a large and light toned Deposit that was once thought to be a Salt Deposit. As a matter of fact, we do not know - yet - the exact composition of the Deposit, but it is not really that bright: the truth is that Rocks and Sands that surrounds it are exceptionally dark and that makes the Deposit itself to appear (---> seem) almost white.

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 19019) 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.
