Utopia_Planitia-Smoke-A-M0202863-PCF-LXTT.jpgControversial Surface Feature in Utopia Planitia (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)248 visiteSiamo all'interno di un grande cratere da impatto nella parte occidentale della Regione di Utopia. Sul bordo interno del cratere, che vedete a centro immagine, ci sono dei cracks (--->fratture) piuttosto evidenti. Nei due detail mgnf che seguiranno, potrete vedere come da uno di questi cracks sembra che stia uscendo un denso fumo nero.
Prima di sposare l'ipotesi del fumo che fuoriesce dalla frattura o prima di rigettarla seccamente, ricordate che siamo a circa 380 Km di distanza dal fenomeno - qualunque esso sia - e che Marte, pi passa il tempo e pi cerchiamo di indagarlo e studiarlo, pi ci appare indecifrabile... MareKromium

Craters-Unnamed_Defrosting_Crater-PIA03921-01.jpgUnnamed Defrosting Crater (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)247 visiteCaption NASA originale:"This MGS-MOC image shows a Surface in the South Polar Region, covered by CO2 Frost. In this springtime scene, the Frost has begun to sublime so that Sandy Surfaces exhibit an abundance of Dark Spots. The circular depression is probably the remains of an Impact Crater. In summer, the Spotted Surfaces in this image would be darker than their surroundings, because they are patches of Windblown Sand".
Location near: 67,6 South Lat. and 254,3 West Long.

Craters-Unnamed_Crater-PIA07202-PCF-LXTT.jpgUnnamed Crater with Pedestal (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunar Explorer Italia)246 visiteThis Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows an Unnamed Impact Crater, a little over 2 Km (> 1,2 mi) in diameter, located in Noachis Terra near 50,4 South and 14,3 West. The Crater's Bouldery Ejecta Blanket has protected underlying material from being eroded away by wind, leaving the Ejecta up on a low Pedestal. This picture covers an area about 3 Km (approx. 1,9 miles) across, and is illuminated by sunlight from the lower left.MareKromium

Utopia_Planitia-PIA07839.jpgPolygons in Utopia Planitia (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)241 visiteCaption NASA originale:"This MGS-MOC image shows a typical view of Polygon-cracked and Pitted Surfaces unique to Western Utopia Planitia. No other place on Mars has this appearance. Some Mars scientists have speculated that ground ice may be responsible for these landforms".

Fienga - Lunexit Team)241 visiteCaption NASA originale:"This MGS-MOC image shows remnants Buttes and Knobs of light-toned rock, perhaps sedimentary in origin, on the Floor of Rabe Crater. The Buttes and Knobs are surrounded by dark, windblown Sands which have been criss-crossed by Dust Devil Tracks".
