OPP-SOL901-PIA08753-001.jpgBeagle Crater and 360° Panorama from Sol 901 through 904 (1)55 visiteCaption NASA originale:"This 360° view shows one of Opportunity's last stops on the now-familiar surface of Meridiani Planum before reaching different terrains associated with the very large Victoria Crater. In the center of the mosaic - frames 7 to 11 - is Beagle Crater, an impact crater about 35 mt (115 feet) wide. On the far left and wrapping around to the far right, Opportunity's tracks are visible approaching the crater".

OPP-SOL901-PIA08753-003.jpgBeagle Crater and 360° Panorama from Sol 901 through 904 (3)55 visiteCaption NASA originale:"Because impact craters have well-understood shapes when they form, the altered appearance of eroded craters gives scientists clues to the processes that modified them. By observing how filled an impact crater has become and how worn its edges are, scientists can estimate how long its surface has been exposed to erosion. The many-sided outline of a crater such as Beagle and the blocky appearance of its ejecta may also tell scientists about the strength of the underlying bedrock. Based on observations such as these, scientists know that Beagle Crater is fresher than Eagle and Fram craters near Opportunity's Landing Site and more similar in form to Viking and Voyager craters in the plains to the North of Beagle".

SOL964-2F211941015EFFAS00P1219L0M1.jpgA little movement for Spirit? - Sol 96455 visiteCaption NASA:"Left Front HazCam Non-linearized Full frame EDR acquired on Sol 964 of Spirit's mission to Gusev Crater at approx. 12:10:38 MLT.
Plans called for Spirit to acquire images of the Rover's tracks with the NavCam, take microscopic images of the Filter and Capture Magnets, and place the Alpha Particle X-ray Spectrometer on the Capture Magnet. Plans also called for the Rover to acquire Hazard Avoidance Camera images of the work volume reached by the Rover's Robotic Arm, monitor dust on the PanCam mast assembly, survey the horizon with the PanCam, and search for morning clouds with the NavCam".

OPP-SOL943-1P211905036EFF7600P2382R2M1.jpgApproaching the "rim" of Victoria (1) - Sol 94355 visiteQuattro immagini PanCam, ottenute fra le 14:24 e le 14:31 MLT, le quali ci mostrano il bordo ("rim") del Cratere Victoria, ora distante solo poco più di 100 metri.
Per correttezza e completezza, informiamo i Lettori che tutti e quattro i frames in oggetto sono stati "digitalmente" ripuliti, in modo da rendere l'immagine meno sgradevole (il prodotto "NASA-raw" era davvero pessimo).

OPP-SOL943-1N211903908EFF7600P1968R0M1.jpgA HUGE "Martian Sandglass"! (1) - Sol 94355 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"?...

The Rings-PIA08275.jpgThe Rings55 visiteCaption NASA originale:"This wide and sweeping view of the sunlit Rings of Saturn takes in the impressive variety in their structure -- from the clumpy and perennially intriguing F-Ring to the many waves, ringlets and gaps in the A and B Rings and the Cassini Division in between.
The image was taken in visible light with the Cassini spacecraft wide-angle camera on Sept. 9, 2006 at a distance of approx. 640.000 Km (about 397.000 miles) from Saturn. The view was acquired from about 10° below the Ring-Plane. Image scale on the sky at the distance of Saturn is approx. 35 Km (about 22 miles) per pixel".
