Hills_with_Snow-MGS-PCF-LXTT.jpgWould you like to ski on Mars? (Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)189 visiteUna fantastica ripresa effettuata dalla Sonda MGS ci permette di vedere degli abbondanti depositi di neve (o di qualcosa che alla neve assomiglia davvero moltissimo) sui fianchi di alcune colline Marziane. Non c'è nulla di scientifico nel desiderio di dare un'occhiata da vicino a questi pendii innevati: Scienza è anche Curiosità e, come già dicemmo in passato, Bellezza. L'idea di passeggiare (o anche di sciare, perchè no?...) alle pendici di una montagna di Marte che giace, parzialmente ricoperta di neve, in uno spesso ed inviolabile silenzio, la troviamo splendidamente affascinante. Chissà se, un giorno, una simile passeggiata potrà essere davvero possibile e chissà chi sarà il primo Uomo (o la prima Donna) a farla...MareKromiumSet 17, 2011

Hills-Utopia_Planitia-PCF-LXTT.jpgBouldery Hill in Utopia Planitia (Natural Colors; credits for the additional process. and color: Dr Paolo C. Fienga - Lunexit Team)153 visiteCaption NASA originale:"Boulders are one of the possible keys to determining which processes have eroded, transported and deposited material on Mars (i.e.: Landslides, Mudflows, Flood Debris etc.).
During the first year in orbit, MGS-MOC obtained pictures with resolutions between 2 and 30 mt per pixel. It was found that Boulders are difficult to identify on Mars in images with resolutions worse than about 2-3 meters per pixel. Some rather larger Boulders (larger than about 10 mt in size) have already been seen on Mars by the orbiting camera.
This is a feat similar to that which can be obtained by "spy" satellites on Earth. The MOC image 53104 subframe shown here features a low, rounded Hill in South/Eastern Utopia Planitia. Each of the small, lumpy features on the top of this Hill is a Boulder.
In this picture, Boulders are not seen on the surrounding Plain. These Boulders are interpreted to be the remants of a layer of harder rock that once covered the top of the Hill, but was subsequently eroded and broken up by weathering and wind processes".MareKromiumSet 17, 2011

North_Polar_Features-North_Polar_Margin-Chasma_Boreale-PIA07052-PCF-LXTT.jpgNorth Polar "Scarp" (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)243 visiteCaption NASA:"This 1,6 meters (~5 feet) per pixel Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a typical North Polar Scarp and associated dark windblown Sand Dunes. Layers of material -- possibly Dust and Ice -- are exposed by the Scarp. The small white patches in the image are remnants of seasonal Frost. When this North Polar image was acquired in late September 2004, most of the Polar Frost had sublimed away. This image is located near 85,1° North Lat. and 210,8°West Longitude. The scene covers an area of approximately 3 Km (about 1,9 mi) across, and is illuminated by sunlight from the lower left.MareKromiumSet 17, 2011

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)229 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.MareKromiumSet 16, 2011

Craters-Buried_Crater-01.jpgUnder the Sand (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)215 visiteCaption NASA originale:"This MGS-MOC image shows a partially-buried crater in the North Polar Region of Mars.
The circular feature is surrounded and partly overlain by some of the many, many sand dunes in the area. The steepest slopes on each dune — their "slip faces" — face toward the SouthEast, indicating that the dominant winds responsible for sand transport in this Region come from the NorthWest".

Dark Slope Streaks occur where some of the Dust has slid down the layered Slopes".
