North_Polar_Features-Dunes-PCF-LXTT.jpgThe Frozen Dunes of the North in early Spring (Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)58 visiteCaption NASA originale:"This MGS-MOC image shows a group of sand dunes, covered by seasonal Carbon Dioxide frost, in the Martian North Polar Region. Over the course of Northern Hemisphere Spring, the CO2 frost sublimes away, slowly revealing the dark sand that makes up the dunes. The dark spots in this image may be patches of freshly-exposed sand, or they could be places where the CO2 frost has changed, either becoming rougher, coarser-grained (larger crystals), or both. A rougher or coarser-grained surface will appear darker because of an increase in shadowing of the surface by the small-scale roughness elements".

Fienga - Lunexit Team)55 visiteSiamo proprio certi che nei canaloni della Regione Marziana di Cerberus Fossae non vi sia nulla di interessante (a parte accumuli di polveri e dunette)?!?
Osservate bene...

Volcanoes-Unnamed_Volcano_in_Syria_Planum-MGS.jpgBuried Volcano in Syria Planum (Original NASA/MGS/MSSS b/w Frame)58 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".
Location near: 13,0° South Lat. and 102,6° West Long.

Controversial_Features-The_Bridges_of_Meroe_Patera-MGS-2.jpgThe "White Bridges" of Meroe Patera (Original NASA/MGS/MSSS b/w Frame - EDM)55 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.

Controversial_Features-The_Bridges_of_Meroe_Patera-MGS-1.jpgThe "White Bridges" of Meroe Patera (Original NASA/MGS/MSSS CTX b/w Frame)54 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".

Sysiphi_Planum-MGS-PCF-LXTT-02.JPGSysiphi Planum (Original NASA-MSSS RAW b/w Frame)56 visiteCaption NASA originale:"This MGS-MOC image shows a spine of material exposed in the Sisyphi Planum Region of Mars.
Gullies can be seen on the deeply-shadowed ridge slope.
Mass movement (landsliding - maybe?) has contributed to the erosion of this ridge and the creation of the apron of talus that surrounds it".

Volcanic_Features-Collapse_Pit_Chain-MGS.JPGCollapse Pit-Chain in Tharsis Region (Original NASA/MGS/MSSS b/w Frame)76 visiteCaption NASA originale:"This MGS-MOC image shows a chain of collapse pits on a dust-mantled, lava-covered plain North-East of Ascraeus Mons (one of the giant volcanoes located in the Tharsis Region of Mars).
Pit chains are associated with collapse which may be driven by several processes including, but not limited to, crustal extension owing to tectonic processes and the collapse of the roof of a lava tube".
Location near: 14,8° North Lat. and 99,1° West Long.
Image width: ~3 Km (~1,9 mi)
