OPP-SOL943-B_P2382_R2-B943R1-1.jpgOnly 50 meters away... (1) - Sol 94354 visiteCaption NASA originale:"A drive of about 60 mt (approx. 200 feet) on the 943rd Sol, of Opportunity's exploration of Mars' Meridiani Planum Region (such as Sept. 18, 2006) brought the NASA Rover to within about 50 mt (approx. 160 feet) of the rim of Victoria Crater.
This crater has been the mission's long-term destination for the past 21 Earth months. Opportunity reached a location from which the cameras on top of the Rover's mast could begin to see into the interior of Victoria.
This frame was taken on Sol 943 by the PanCam and it shows the upper portion of interior crater walls facing toward Opportunity from up to about 850 mt (half a mile) away. The amount of vertical relief visible at the top of the interior walls from this angle is about 15 mt (roughly 50 feet). The exposure was taken through a PanCam filter selecting wavelengths centered on 750 nanometers".

OPP-SOL943-B_P2382_R2-B943R1-2.jpgOnly 50 meters away... (2) - Sol 94354 visiteCaption NASA originale:"Victoria Crater is about five times wider than Endurance Crater - which Opportunity spent six months examining in 2004 - and about 40 times wider than Eagle Crater, where Opportunity first landed. The great lure of Victoria is the expectation that a thick stack of geological layers will be exposed in the crater walls, potentially several times the thickness that was previously studied at Endurance and therefore, potentially preserving several times the historical record".

OPP-SOL943-1N211903908EFF7600P1968R0M1.jpgA HUGE "Martian Sandglass"! (1) - Sol 94354 visiteUna nuova Clessidra Marziana ma, questa volta, larga almeno un paio di metri e profonda poco meno di uno.
I bordi smussati e l'assenza di ejecta ci fanno escludere l'ipotesi cratere (anche - ed eventualmente - secondario); la NASA - ovviamente - non ha commentato il frame in questione (forse per mancanza di argomentazioni).
Ancora grandi complimenti al Dr Pullini per la Sua bellissima intuizione (che, un giorno - speriamo - verrà confermata anche "ufficialmente") ed una domanda - vecchia, ma sempre attuale -: come mai Meridiani Planum sta "sprofondando"?...
