This NASA - Mars Global Surveyor (MGS) - Mars Orbiter Camera (MOC) image shows us a bright Plain located to the West of the famous Schiaparelli Crater, which hosts several interesting Surface Features: some of them, are long-lived; others, instead, are just transient. The Circular Surface Features scattered somewhat randomly throughout the entire scene, are Impact Craters, all of which are in a variety of so-called "States of Degradation" (however, and as far as we can see, all the Impact Craters that are visible in this frame look quite old, eroded and even partially buried). Toward the upper left (Sx - North/West) corner of the image, there is a small Hill surrounded by Ripples of Windblown Sediment, and near the center (a little to the right - Dx) of the image, there is an active Dust Devil (one of the so many thousands that we have seen so far, from above - i.e.: from orbit - as well as from the Surface), casting a small shadow towards the South/East, as it makes its way across the Plain". This frame has been colorized in Absolute Natural Colors (such as the colors that a human eye would actually perceive if someone were onboard the NASA - Mars Global Surveyor 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. |
