The cause of such variation is unknown".MareKromium

Craters-Holden_Crater-1-M0302733.jpgHolden Crater floor near intersection with Uzboi Vallis (1)61 visiteQuesta serie di 4 frames (ottenuti da un solo frame, troppo grande e troppo dispersivo per essere pubblicato unitariamente) non mostra quello che si potrebbe immaginare pensando al 'fondo' di un cratere.
In realtà, quello che vediamo da questa serie di immagini - ottenute da un'altezza di circa 374 Km - è un autentico "mondo in sè", fatto di rilievi assolutamente fantastici e suggestivi i quali, in alcuni punti, sembrano ricordare le "Bianche Scogliere di Dover" (the "White Cliffs of Dover"). Come questo paesaggio possa apparire ai nostri occhi dal Datum "0" (cioè dalla superficie) non possiamo saperlo, ma la nostra sensazione è che si tratterebbe di uno spettacolo indimenticabile...

Aeolian_Features-Windstreaks-PIA03935-00.jpgWindstreaks (Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)58 visiteCaption NASA originale:"Windstreaks are features caused by the interaction of Wind and Topographic Landforms. The raised Rims and Bowls of Impact Craters cause a complex interaction such that the Wind Vortex in the Lee (--->sedimento) of the Crater can both scour away the Surface Dust and deposit it back in the center of the Lee. If you look closely, you will see evidence of this in a darker Rim enclosing a brighter interior. These Windstreaks are located in the region between Gordii Dorsum and Amazonis Mensa".
