Knobs-Deuteronilus_Mensae-20080514a-PCF-LXTT.jpgHighly Reflective "Knobs" in Deuteronilus Mensae (Enhanced Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)56 visiteDifficile dare una spiegazione (al di là della over-saturation del frame - idea razionale ma che, a nostro avviso, in questo caso non tiene...) per giustificare l'albedo elevatissima dei lati esposti al Sole di queste colline "a ceppo" (knobs).
Il Prof. Hoagland, quando si trovò in una situazione visiva simile (a proposito della Sfinge di Cydonia), disse che l'albedo elevata poteva giustificarsi solo pensando ad un residuo di "piastrellatura vetrosa" della "Sfinge" (o "Faccia di Marte") la quale, colpita dai raggi radenti del Sole del primo mattino, brillava come un faro.
Beh, Cari Amici, che dire? Una cosa è certa: se la Sfinge brillava (e brilla) così perchè era ed è "piastrellata", allora anche queste collinette sono "piastrellate"...

North_Polar_Region-The_Erg-PIA07820-00.jpgFeatures of the North Polar Erg (Original NASA/JPL/ASU b/w Frame)57 visiteCaption NASA:"Sand Seas on Earth are often called "Ergs", an Arabic name for Dunefield, but a Sand Sea DIFFERS from a Dunefield in - at least - two ways:
1) a Sand Sea has a LARGE regional extent and
2) the individual Dunes forming the Sand Sea are LARGE in size and complex in form.
This VIS image was taken at 82° North Latitude during Northern Spring. The Dunes are still partially frost covered. This Region is part of the North Polar Sand Sea: so note the complexity and regional coverage of the Dunes".
Image information: VIS instrument;
Latitude: 81,2° North;
Longitude: 118,2° East (such as 241,8° West);
