PSP_001474_2520_RED-new_lake-00.jpgThe Northern Lakes: Lake "Lunexit" (context image)70 visiteQuando si sa dove guardare e che cosa cercare...Si finisce SEMPRE (o quasi...) con il trovare.
L'albedo del dettaglio che vedete a mezza altezza alla Vostra Sx è assolutamente INCONFONDIBILE.
Il detail-mgnf che abbiamo operato (e che vedrete nel prossimo quadro) è chiarissimo: c'è un nuovo Lago nelle Grandi Pianure Nordiche di Marte!
"Lake Lunexit", in onore della nostra Fondazione di Ricerca e di coloro che la rendono viva, e cioè i vari Lorenzo Foschini, Gianluigi Barca, Matteo Fagone, Alessio Feltri, Lorenzo Leone e tanti altri Ricercatori ed Appassionati che, con grandissima umiltà e modestia, stanno contribuendo a scrivere una (piccola, ma non per questo insignificante) porzione della Storia del Pianeta Rosso (nota: Lake Lunexit è stato battezzato - purtroppo - "unofficially", ma con buona pace di IAU, NASA, ESA e di tutti i Fenomeni che guardano, guardano, guardano...senza vedere mai niente e poi blaterano, blaterano e blaterano...senza dire mai nulla!).

PSP_008017_2020_RED_abrowse.jpgCraters in Isidis Planitia (MULTISPECTRUM; credits: Lunexit)70 visiteThis image shows a young impact crater in the Northern part of Isidis Planitia. The crater is fresh enough to preserve some fine textures that are eroded around other craters.
The ejecta blanket of material thrown out of the crater is distinctly dark and rough, with many small boulders and rugged texture. To the South of the crater there is a wedge-shaped area with little ejected material. This may indicate that the impactor which formed this crater came from the south, since at moderate impact angles ejecta is preferentially thrown in the direction of motion of the impactor.
Eventually, a combination of erosion and mantling by dust will smooth and obscure the ejecta and cover over the crater, turning it into a shallow depression like the others in this image. Reworking of the crater is already beginning, as shown by the network of fine ridges (wind-blown ripples) on the crater floor.MareKromium
