(2 - edm; credits: Roberto Tremolada)166 visiteMagnificazione del dettaglio che, nel frame precedente, era indicato da una freccia gialla: si tratta di una sorta di "doppia-ruota" o, se volete, della porzione esterna di due "anelli di vario diametro" (tipo quelli che vengono posizionati sui manubri nelle prove e competizioni di sollevamento pesi) i quali giacciono, semi-interrati, a pochi centimetri dai Pannelli Solari del Rover.
Che dire? Il dettaglio è assai intrigante e, senza dubbio, merita un'analisi ed una riflessione adeguata; non sembra (SEMBRA!) trattarsi, infatti, di un qualcosa di "naturale" - nel senso canonico del termine -; tuttavia, e Voi questo lo sapete bene, la nostra (umana) tendenza in virtù della quale si tende ad associare, prima visivamente e poi logicamente, dei rilievi ignoti a dei rilievi noti (si dice che "ci si muove induttivamente, da forme ignote verso forme note) ci ha sovente tratti in inganno.
La "morale"? Noi Vi proponiamo il dettaglio, ma NON POSSIAMO dirVi "che cos'è". Per ora nessuno Vi potrà mai dire con CERTEZZA che cosa un oggetto/rilievo anomalo/singolare "è" effettivamente.
E chiunque lo facesse, agirebbe in malafede (dato che costui sa BENE di non poter dare certezza alcuna su quello che, in immagini spesso sfuocate e poco definite, sembra vedersi...).
Tutto qui.
Complimenti a Roberto, sempre un attento osservatore: complimenti comunque e di Cuore!MareKromium     (4 voti)

Titan-PIA10546.jpgNorth Polar Haze (Saturated Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)59 visiteCaption NASA:"Titan's globally distributed detached haze layer and the moon's North Polar hood, both notable details of its thick atmosphere, are clearly seen in this image from the Cassini Spacecraft.
Titan is about 5150 Km (approx. 3200 miles) across, and therefore slightly larger than Mercury.
The image was taken with the Cassini Spacecraft narrow-angle camera using a combination of spectral filters sensitive to wavelengths of polarized ultraviolet light centered at 338 nanometers. The view was obtained at a distance of approx. 1,7 MKM (about 1,08 MMs) from Titan and at a Sun-Titan-Spacecraft, or Phase, Angle of 50°.
Image scale is roughly 10 Km (about 6 miles) per pixel".MareKromium     (4 voti)

PSP_006477_1745_RED_abrowse-00~0.jpgDD Tracks in Southern Schiaparelli Basin (context frame - False Colors; credits: Lunexit)58 visiteDust-Devils (DD) are vortices of wind that form when air rising from a warm surface encounters shear in the above atmosphere.
Martian Dust-Devils can attain gargantuan proportions, reaching the size of terrestrial tornadoes with plumes that tower up to 9 Km above the surface.
Dust-Devils play an important role in sustaining the aerosols that make up Mars’ Red Sky and in cleaning the Martian Surface after a Dust Storm.
Nota Lunexit: sono quindi i DD, secondo la NASA, la "causa maggiore" del Cielo Rosso di Marte? Interessante riflessioni ed interessante quesito: dunque il Cielo di Marte NON E', naturalmente, "rosso" o "arancio", ma è "tinto di rosso/arancio"!
Pensateci sopra...

PSP_009161_1450_RED-00.jpgLong Shadows over Ariadnes Colles (ctx frame- natural colors; credits: Lunexit)59 visiteAriadnes Colles is a labyrinth-like cluster of hills, mesas and knobs located near Terra Cimmeria, in the Southern Highlands of Mars.
This image, which covers a portion of that labyrinth, was acquired only a few Soles away from Winter Solstice.
Winter Solstice occurs in the shortest Sol of the year, when the Sun travels the lowest in the Martian sky, making shadows appear very long. These conditions are ideal to analyze modest relief features, that would pass unnoticed when illuminated from above but are highlighted when illuminated from the side.MareKromium     (4 voti)
