This image shows Early Morning Fog that covers a huge portion of the Noctis Labyrinthus Region of Mars. This Fog, that is probably composed of Water Ice, is confined primarily to the low-lying Troughs, but it extends, occasionally, also over the adjacent Plateau. Noctis Labyrinthus (such as "Labyrinth of the Night") is a Region of the Red Planet that lies between the Valles Marineris Canyon System (actually, the Westernmost End of the Valles Marineris Canyon System) and the Volcanic District of Tharsis (the upland part of Tharsis, to be more precise). It is located in the so-called Phoenicis Lacus Quadrangle and it is notable for its maze-like system of deep, steep-walled Valleys. It is very likely that the Valleys and Canyons existing in the Noctis Labyrinthus Region formed by faulting; in addition, many of them show classic features of Grabens (----> in Geology, Grabens are depressed blocks of land bordered by parallel faults and Graben is a German word meaning ditch or trench), with the upland plain surface preserved on the Valley Floor. In some places of the Region, the Valley Floors are much rougher, often disturbed by Landslides, and there are places where the land appears to have sunk down into Pit-like Formations. Many Scientists believe that this faulting could have been triggered by some powerful Volcanic Event that occurred in the Tharsis District, but hardly a definitive proof supporting this aforementioned hypothesis shall ever be found. The portion of the Noctis Labyrinthus Region shown here is about 300 Km across. This frame has been colorized in Absolute Natural Colors by (such as the colors that a human eye would actually perceive if someone were onboard the NASA - Viking Orbiter 1 and then looked towards the Noctis Labyrinthus Region of Mars), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team. |
