In this VIS image, taken by the NASA - Mars Odyssey Orbiter on July 22nd, 2013, and during its 51.332nd orbit around the Red Planet, we can see quite a few of the most common Martian Aeolian (---> Wind caused) Surface Features, such as the so-called "Windstreaks". The specific direction of the Windstreaks that are visible here, in the Meridiani Planum Region of Mars, indicates that the Dominant Winds are blowing from the East towards the West.

This frame (which is an Original Mars Odyssey Orbiter b/w frame published on the NASA - Planetary Photojournal with the ID n. PIA 17488) has been additionally processed, magnified, contrast enhanced, Gamma corrected and then colorized in Absolute Natural Colors (such as the colors that a 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.
