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) 182 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

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)201 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 è (nè potrebbe comunque essere) vegetazione.
Questi sono i dati e le informazioni disponibili: come vedete, c'è materiale su cui riflettere...MareKromium

Psp_001700_2505_red-00~0.jpgLauth Crater and the Frozen "Pseudo-Lake" of Vastitas Borealis (CTX Frame - Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)310 visiteThe right side of PSP_001700_2505 shows a portion of a Frost Patch on a Mound inside a Northern Hemisphere Crater (unofficially known as "Lauth Crater").
The Frost Patch has remained largely stable at least since the Viking era (late 1970s). The bright Frost Region is bounded by a Dunefield on the North-East. Several sizes of Dunes are visible. The size classes probably represent generations of Dunes that formed under a variety of dominant wind conditions. MareKromium

The Frost is largely absent over the Dunes and is more stable over the Ground that does not have Dune-shaped Landforms.MareKromium
