PSP_003141_1330_RED_abrowse-00-PCF-LXTT.jpgThe Dunes of Kaiser Crater (CTX Frame - Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)114 visiteCaption NASA:"Image PSP_003141_1330 shows a Sand Dunefield in Kaiser Crater, a 210 Km (such as about 130 miles) wide Impact Basin in the Hellespontus Region of Mars.Winds have trapped massive quantities of Sand on the Floors of broad Craters in this Region.
The steepest slopes on each Dune, such as the Slip-Faces, point to the East indicating that the dominant wind direction in this part of the Dunefield is from West to East. Patches of seasonal frost can be seen in the low areas between the Dunes".
Nota Lunexit: noi non crediamo che che le aree ad albedo più elevata (e che appaiono di un bel color bianco/argento nel frame colorizzato) le quali sono chiaramente individuabili fra le dune sìano, come dice la NASA, "chiazze di brine ghiacciate".
O meglio: può darsi che esse lo sìano, così come è pure plausibile che si tratti di sabbie cristalline (ne abbiamo già incontrate nei Campi di Dune) o di porzioni di suolo libere dalle sabbie (e che magari evidenziano il "Martian Paving"...) MareKromium

PSP_003141_1330_RED_abrowse-01-PCF-LXTT.jpgThe Dunes of Kaiser Crater (EDM - Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)102 visiteThis EDM reveals smaller Secondary Dunes superimposed on the Surface of the large Dunes and even smaller Ripples that appear between and perpendicular to the Secondary Dunes. Avalanching or mass movement of sand has left deep scars on the Slip-face of the large dune in the upper left portion of the frame. This may indicate that the sand is not loose but is weakly cemented. MareKromium
