South_Polar_Features-Crater_with_Ice-A-M1000628-00.jpgSouth Polar Crater with residual Ice (CTX Frame)55 visitePer questo frame devono essere ripetuti i medesimi commenti svolti a proposito degli altri rilievi "anomali" Sud-Polari e che possiamo così, sommariamente, riassumere:
1) esistono innumerevoli immagini che 'sembrano' mostrare zone lacustri nell'area Sud-Polare;
2) è poco probabile - nonchè poco credibile - che TUTTE le immagini in questione sìano ingannevoli;
3) è un dato dimostrabile quello attinente il rimpicciolimento dei Poli: i ghiacci polari si stanno ritraendo;
4) un tale fenomeno accade, molto probabilmente, in caso di rialzo della temperatura del Pianeta (effetto serra?!?);
5) se la temperatura di Marte si è realmente alzata oltre una certa soglia, allora è realmente possibile che, in determinati periodi dell'anno, risulti possibile trovare acqua allo stato liquido in superficie;
6) se è possibile rinvenire acqua allo stato liquido in superficie, allora bisogna iniziare a riscrivere tutte le teorie sullo 'stato di salute' del Pianeta Rosso;
7) le speculazioni di cui ai punti precedenti...

Tutto ciò premesso, la domanda di chiusura è facile (e la conoscete anche Voi): che cosa stiamo guardando?

South_Polar_Features-Defrosting_Dunes-2005_06-00.jpgDefrosting Dunes (Original NASA/MGS/MSSS b/w Frame)77 visiteCaption NASA originale:"This MGS-MOC image shows dark spots formed in carbon dioxide frost that covers the surfaces of patches of sand in the South Polar Region. As spring arrived this year in the Martian Southern Hemisphere, so began the annual defrosting process.
The fact that sand dunes begin to defrost earlier than other surfaces and that the defrosting process involves the formation of spots like these, has been known since the earliest days of the MGS mission".
Location near: 66,8°S; 15,7°W

South_Polar_Features-Fans-PIA08658.jpgSouth Polar Fans (Original NASA/MGS/MSSS b/w Frames)54 visiteCaption NASA originale:"Dark spots (left) and 'Fans' appear to scribble dusty hieroglyphics on top of the Martian South Polar Cap in two High-Resolution MGS-MOC images taken in Southern Spring. Each image is about 3-Km wide".

South_Polar_Features-Fog_over_Chasma_Australe-PCF-LXTT.jpgFog over Chasma Australe (Absolute Natural Colors; credits for the additional process. and color: Dr Paolo C. Fienga - Lunexit Team)56 visiteCaption NASA originale:"Fog is a common occurrence in some areas of the retreating South Polar Seasonal Frost Cap. Fogs are commonly banked-up against steep Slopes or found inside Defrosting Craters.
This MGS-MOC image captured mid-afternoon Fog banked against the Layered Walls of Chasma Australe, a Trough in the South Polar Region of Mars. The Frost-covered Layers of Chasma Australe can be seen on the right side of this image, while the billowy Fog is to the left.
Sunlight illuminates this scene from the upper left. The Fog, probably composed of water ice crystals, casts shadows on the Chasm's Wall.
This picture is located near 83,5° South Lat. and 257,9° West Long; it covers an area about 3 Km (1.9 mi) wide". MareKromium

South_Polar_Features-Isolated_Knob-PIA03977-PCF-LXTT.jpgSouth Polar Features: Layered Knob (Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)196 visiteCaption NASA originale:"This MGS-MOC image shows a small, relatively light-toned Knob of Layered Material and the erosional expression of the underlying layers, in the South Polar Region of Mars. When the image was acquired in April 2005, the surface was still covered with seasonal carbon dioxide frost. Dark spots and streaks mark locations where the frost had begun to change and sublime away".

South_Polar_Features-Layers-PCF-LXTT.jpgSouth Polar Layers (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)145 visiteCaption NASA originale:"This MGS-MOC image shows remnants of Layered Materials near the West Rim of a Southern Unnamed Crater. The composition of these layered rocks is unknown — are they the remains of sedimentary rocks or accumulations of dust and ice? We'll probably not know until someone visits this area, perhaps centuries from now".
