South_Polar_Regions-South_Pole.jpgThe South Pole of Mars (Natural Colors; credits: NASA/MGS/MSSS)210 visiteCaption NASA:"During Spring, the Ice Cap - predominantly formed by layers of frozen carbon dioxide (dry ice) plus some water ice - begins to shrink as the ices change directly from solid to gas (cosiddetta "sublimazione"). Hazy clouds of ice crystals and fog extend across the bottom of the picture and a darker, more defrosted area, is visible at the upper right, near the Red Planet's night side".

Craters-Lau_Crater-M07_4748_4749-PCF-LXTT-01.jpgBizarre-looking "Dark Spot" near Lau Crater (EDM - Absolute Natural Colors; credits for the additional process. and color: Dr Paolo C. Fienga - Lunexit Team)210 visiteLa chiazza scura e senza nome che la NASA stessa definisce di "natura sconosciuta" potrebbe essere l'evidenza, secondo alcuni Ricercatori Americani ed Europei, di una minuscola area di Marte con "vegetazione". Si, avete letto bene: vegetazione, di un qualche tipo. In un'altra immagine della stessa zona, la macchia scura appare di colore verdastro e non nero. E' del tutto evidente che i sostenitori dell'idea che si tratti di vegetazione (si, ma che tipo?) ritengono che l'immagine NASA sia manipolata, mentre la NASA sostiene che i colori che vedete sono "almost real" e quindi la macchia scura, comunque, non (n potrebbe comunque essere) vegetazione.
Questi sono i dati e le informazioni disponibili: come vedete, c' materiale su cui riflettere...MareKromium

Craters-Newton_Crater-03.jpgNewton Crater's Gullies (Original NASA/MGS/MSSS b/w Frame)206 visiteDa "NASA - Picture of the Day" del 26.6.2000:"...Inside a small crater that lies inside large Newton Crater on Mars, numerous narrow channels run from the top down to the crater floor. The above picture covers a region spanning about 3000 meters across. These and other gullies have been found on Mars in recent HR pictures taken by the orbiting Mars Global Surveyor robot spacecraft. Similar channels on Earth are formed by flowing water, but on Mars the temperature is normally too cold and the atmosphere too thin to sustain liquid water. Nevertheless, many scientists now hypothesize that liquid water did burst out here from underground Mars, eroded the gullies and pooled at the bottom as it froze and evaporated. If so, life-sustaining ice and water might exist even today below the Martian surface (...)". L'idea che ci sia acqua allo stato liquido sotto la superficie di Marte non nuova, anzi: la NASA stessa lo ipotizzava 4 anni fa. Oggi, dopo mesi di esplorazione "in loco", tutto tace. Forse un ripensamento?

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)206 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".

Craters-Lau_Crater-M07_4748_4749-PCF-LXTT-00.jpgFeatures and Proximities of Lau Crater (CTX Frame - Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team) 202 visiteCaption NASA:"The Martian Southern Hemisphere was nearly 2 months into its Spring Season when this picture was taken by the Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) on September 25, 1999. The scene covers a vast, Frost-coated Plain located South of the martian Antarctic Circle. The icy Terrain in the image has an almost pastel-like character, owing to the mixture of reddish Dust both on, in, and under the white Frost. The Frost - mostly frozen water at this time of year - is left over from Winter, which ended on August 2, 1999. One Martian Year is about 687 Earth days long, thus each of the Planet's 4 seasons are nearly twice as long as seasons on Earth.
The largest Crater visible in the upper left of the frame is Lau Crater, named for the Danish Astronomer, Hans E. Lau (1879-1918). The Dark Spot near the center of the image has no name, and its origin is unknown. The picture covers an area about 1.020 Km across by approximately 1.240 Km down.
The center is located near 76 South Lat. and 97 West Long.; North is toward the upper right. Sunlight illuminates the scene from the upper left".MareKromium
