In this truly suggestive VIS image, taken by the NASA - Mars Odyssey Orbiter on April, 20th, 2003, and during its 59.217th orbit around the Red Planet, we can see that the long term action (---> eons) of the Dominant Winds have deeply etched the Surface of the Martian Region known as Memnonia Sulci. The only partially cemented Surface Materials are easily eroded by the Winds' Action, thus creating the so-called "Llinear Ridges" (also known as "Yardangs). However, the multiple directions of the Yardangs visible in this VIS image, indicate that there were - at least - two different Dominant Winds which blew (both for centuries and more) in two different directions in this specific area of Mars. Latitude (centered): 8,33112° South 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 19502) 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. |
