Craters-Unnamed_Crater_with_Frost-00-PCF-LXTT.JPGClouds over "Frosty" Crater (CTX Frame - False Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunar Explorer Italia)56 visiteIl dettaglio della nuvola che scivola sul cratere senza nome situato a Sud-Est del bacino di impatto denominato "Hellas" è molto bello, ma non fermiamoci al dettaglio artistico ed osserviamo il margine interno del cratere posto alla Vostra Sx: le tracce di brina sono evidenti.
E non è tutto: osservate il fondo del cratere. C'è qualcosa che lo "allaga", in parte? Sicuramente non si tratta solo di fango (è l'albedo del dettaglio che ce lo dice).
La nostra prima ipotesi è che, sul fondo di questo cratere senza nome, vi possa essere un discreto quantitativo di ghiaccio d'acqua il quale è talmente trasparente, da permetterci di riuscire a vedere anche i minuscoli crateri che giacciono al di sotto di esso.
La seconda ipotesi, meno immaginifica ma, forse, più realistica, è che sul fondo del cratere vi sia un deposito sottile, ma abbondante, di brina ghiacciata.
Caption NASA:"The dust storm season in the Southern Hemisphere of Mars is well underway. This image of an unnamed crater South-East of Hellas Basin shows the encroachment of a storm in the region".MareKromium
