Psp_010656_2170_red.jpgThe "Omega" Crater of Ismenius Lacus (possible True Colors; credits: Lunar Explorer Italia)53 visite
Per gli amanti dei Misteri Orbitali e delle possibili "Forme Assonanti" (con questa definizione si intendono tutti i rilievi superficiali situati su mondi extraterrestri i quali, in ragione della loro distanza dal punto di osservazione, o per motivi oggettivi - ex.: affinit morfologica -, o per entrambe le ragioni, richiamano alla mente dell'Osservatore dei rilievi superficiali artificiali che sono individuabili sulla Terra), ecco a Voi il (piccolo) "Cratere Omega".
Il nome del cratere (battezzato da noi e quindi, ufficialmente, ancora "Unnamed") lo abbiamo scelto in ragione della sua forma inequivocabile (che ricorda una "Omega", appunto), ma il mistero che lo caratterizza dato da almeno due eccellenti motivi: 1) la sua forma (che - quasi - perfettamente circolare e 2) la lacuna di rim sul suo versante Nord (Sx dell'Osservatore).
Una lacuna decisamente bizzarra non solo perch i suoi margini sono smussati e regolari (vedere per credere!), ma anche perch, se si fosse trattato - come comunque probabile che sia - di un cedimento naturale, allora c' davvero da chiedersi che fine avranno mai fatto i detriti derivati dal crollo...
Insomma: se si vuole, se c' pazienza nella ricerca e nello studio, se si possiede un pizzico di immaginzione e, soprattutto, se e quando si OSSERVA BENE, di rilievi superifciali ambigui (come minimo) se ne possono trovare OVUNQUE!
Ed quest'ultimo dato (la localizzazione: OVUNQUE) che ci spinge, talvolta, a ritenere che le storie sull'esistenza di una possibile - ma antichissima - Civilt Marziana potrebbero possedere un minimo di sostanza (comunque ancora tutta da ricercare e dimostrare, DIMENTICANDO - se possibile - Cydonia Mensae).

Psp_010434_1575_red.jpgFan at Valley Mouth (possible True Colors; credits: Lunar Explorer Italia)52 visiteThis image shows the intersection of a Valley with the floor of a large Impact Crater. The Valley appears to have transported sediment that was deposited on the Crater Floor when the flow slowed. As the Eastern side of the lobate deposit appears to have been sheared off, it is possible that continuing flow from the valley eroded into its own deposits.
The deposit is noticeably different in color from the crater floor, indicating that the Valley transported different sediments. Since the large crater is shallow, likely due to infilling, this suggests that multiple sources of sediment and perhaps multiple deposition processes have affected the geology at this site.
The deposited material in the lobe at the Valley Mouth displays some interesting textural features. Small boulders are commonly present on its surface. This may demonstrate relatively energetic deposition as in a flash flood, although it is possible that the boulders are superimposed debris from later impact craters.
The Southern End of the deposit is also fracturing into blocks or slabs. These could be relics of old mud cracks, or of thermal contraction cracks formed in Permafrost.

Nota Lunexit: la somiglianza fra questo modesto cratere d'impatto (NASA dixit) ed i "Pit Craters" (o crateri a pozzo, correlati a fenomeni di subsidenza e NON a fenomeni meteorici) , a dir poco, straordinaria! L'incredibile rotondit del rilievo, inoltre, ci lascia supporre che, se si trattasse effettivamente di un "impact crater", allora il bolide che lo ha creato dovrebbe essere precipitato - letteralmente - "a piombo" sulla superficie di Marte (ossa con un angolo di impatto pari a circa 90: un evento pi unico che raro!...).
Molto bello e marcato il Windstreak che si diparte dal cratere e che ci lascia supporre l'esistenza di un piccolo margine (rim), non visibile n percepibile a questa risoluzione.MareKromium
