Craters-Unnamed_Crater_with_Pedestal-MGS.jpgUNnamed "Pedestal Crater"59 visiteCaption NASA originale:"This MGS-MOC image shows a "pancake" or "pedestal" crater on the Martian Northern Plains. The rocky ejecta from the crater protected the underlying material from being stripped away by wind, leaving the ejecta standing higher than the surrounding terrain. The rocks in the ejecta are not too clearly seen today, especially at the 6 mt (~20 feet) per pixel scale of this image, in part because they have been covered up by later, mantling material".

North_Polar_Features-North_Polar_Scarp-MGS-00.jpgNorth Polar Panorama (Original NASA/MGS/MSSS b/w Frame)60 visiteCaption NASA originale:"This MGS-MOC image shows a steep slope in the North Polar Region of Mars. The stripes indicate an exposure of layered material; the variations in brightness among the stripes are the result of varying amounts and textures on seasonal Carbon Dioxide (CO2) frost. At the time the image was acquired - such as in June 2006 -, the Carbon Dioxide frost was beginning to sublime way, leaving a variety of different patterns in frost distribution".

Craters-Unnamed_Crater.jpgOn the edge... (Original NASA/MGS/MSSS b/w Frame)69 visiteCaption NASA originale:"This MGS-MOC image shows gullies on the Wall of a Martian South Mid-Latitude Unnamed Impact Crater. The Channels in each Gully head beneath an eroding overhang of layered rock, providing support for the hypothesis that some (if not all) Martian Gullies result from release of groundwater to the Surface".

Volcanoes-Unnamed_Volcano_in_Syria_Planum-MGS.jpgBuried Volcano in Syria Planum (Original NASA/MGS/MSSS b/w Frame)60 visiteCaption NASA originale:"This MGS-MOC image shows a small Volcano in the Syria Planum Region of Mars. Today, the Lava Flows that compose this small Volcano are nearly hidden by a mantle of rough-textured, perhaps somewhat cemented, Dust. The light-toned Streaks that cross the scene were formed by passing Dust Devils, a common occurrence in Syria".

North_Polar_Features-Dunes-MGS-05.jpgNorth Polar Dunes (Original NASA/MGS/MSSS b/w Frame)60 visiteCaption NASA originale:"This MGS-MOC image shows dunes in the North Polar Region of Mars. In this scene, the dunes and the plain on which the dunes reside, are at least in part covered by a bright CO2 frost. Dark spots indicate areas where the frost has begun to change, either by subliming away to expose dark sand, changing to a coarser particle size, or both. The winds responsible for the formation of these dunes blew from the South-West toward the North-East.

North_Polar_Features-Dunes-MGS-10.jpgDefrosting North Polar Dunes (Original NASA/MGS/MSSS b/w Frame)57 visiteCaption NASA originale:"This MGS-MOC image shows a portion of a sand dune field in the North Polar Region of Mars. The dunes are covered with frozen CO2, which accumulated over the Autumn and Winter months in the Northern Hemisphere. During the Spring, the time at which this image was acquired, the CO2 begins to sublime away, going directly from solid to gas, just as dry ice does here on Earth.
The dark spots, streaked by blowing winds, may be places where the frost has been removed (exposing underlying dark sand), places where the grain size or roughness of the frost has increased (increasing shadowing due to the change in texture), or both".

Aeolian_Features-Dust_Devil-MGS-00.jpgRunning Winds... (Original NASA/MGS/MSSS b/w Frame)57 visiteCaption NASA originale:"This MGS-MOC image shows a bright plain West of Schiaparelli Crater, which is host to several features, some of them long-lived and others that are transient. The circular features scattered somewhat randomly throughout the scene are impact craters, all of which are in a variety of states of degradation.
Toward the right (Dx - South-West) corner of the image, there is a small hill surrounded by ripples of windblown sediment, and near the center (a little to the left) of the image, there is an active DD casting a shadow to the east as it makes its way across the plain".

Controversial_Features-The_Bridges_of_Meroe_Patera-MGS-2.jpgThe "White Bridges" of Meroe Patera (Original NASA/MGS/MSSS b/w Frame - EDM)58 visiteLi abbiamo chiamati "ponti", ma ovviamente si tratta di qualcosa di molto diverso da una serie di "ponti ad arco". Per il Dr Feltri si potrebbe trattare di enormi bio-strutture; per il Dr Skipper si tratta di ciclopici manufatti in parte sepolti.
La nostra posizione al riguardo di questi "Bianchi Ponti" i quali si vedono anche in altre Regioni Marziane è interlocutoria: sappiamo che si tratta di caratterizzazioni superficiali talmente peculiari da potersi definire, in tutta tranquillità, cime Anomalìe di Superficie (Anomalìe che la NASA e l'ESA, ovviamente, non vedono e non commentano...); sappiamo che non sono dune e che la loro morfologia NON sposa la morfologia dell'ambiente a cui esse accedono (e dunque sono rilievi - tecnicamente - "alieni") e che, con ogni probabilità, si tratta di rilievi (effettivamente) di dimensioni enormi i quali non hanno riscontri similari nè sulla Terra, nè su nessun altro Corpo del Sistema Solare.
Questi, a nostro parere, sono i fatti.Lug 12, 2006

Controversial_Features-The_Bridges_of_Meroe_Patera-MGS-1.jpgThe "White Bridges" of Meroe Patera (Original NASA/MGS/MSSS CTX b/w Frame)56 visiteCaption NASA originale:"This MGS-MOC image shows terrain South-West of Meroe Patera in Syrtis Major Planum, Mars. Wind streaks formed in the "lee" (the downwind side) of impact craters are common throughout the scene, including the small impact crater near the center of the image with light-toned ejecta radiating outward from its rim.
Near the South (Dx) of the image, 3 light-toned slope streaks, created by dry mass movements of dust, extend down the sloping side walls of two overlapping impact craters".
