Pandora-PIA12690.jpgPandora57 visiteCaption NASA:"The Cassini Spacecraft captured this close view of Saturn's moon Pandora during the Fly-By on June, 3, 2010.
Pandora is approx. 81 Km (a little mora than 50 miles) across and orbits beyond Saturn's thin F-Ring, which is shepherded by Pandora and Prometheus.
This view looks toward the Saturn-facing side Pandora. North on Pandora is up and rotated 20° to the left.
The image was taken in Visible Light with the Cassini Spacecraft narrow-angle camera. The view was obtained at a distance of approx. 101.000 Km (about 63.000 miles) from Pandora and at a Sun-Pandora-Spacecraft, or Phase, Angle of 28°.
Image scale is 603 meters (1980 feet) per pixel".MareKromium

Dione_and_Titan-NOO152440-86-EB.gifDione, Titan and some "Mistery Moons"... (GIF-Movie - Natural Colors; credits: ELisabetta Bonora - Lunexit Team)59 visite...Il filmato è, semplicemente, di straordinaria fattura (un "Grazie di Cuore!" alla nostra Amica e Partner, Elisabetta Bonora), ed i suoi contenuti, come qualsiasi Appassionato di Astronomia potrà notare, sono - ancora una volta - estremamente suggestivi.
Titano, dal punto di vista dell'Orbiter Cassini, "scivola" accanto a Dione.
Ma sono soltanto Dione e Titano i "Protagonisti" di questo "inseguimento" nella Notte di Saturno?
Ebbene, se avete presente e chiaro il concetto di "Risonanza Orbitale" e se osservate MOLTO attentamente il filmato, alla risposta potreste e dovreste arrivare da soli...MareKromium

Enceladus-PIA11697.jpgThe South Pole of Enceladus56 visiteCaption NASA:"This wide-angle image shows the South Polar Region of Saturn's moon Enceladus and outlines the area covered by the High-Resolution mosaic combining data from the Imaging Science Subsystem and Composite InfraRed Spectrometer onboard the NASA's Cassini Spacecraft (see the frame PIA11696).
The outlined area focuses on Baghdad Sulcus, a fracture in the South Polar Region.
Cassini captured the data for this wide-angle image during the Spacecraft's close Fly-By of the moon that occurred on Nov. 21st, 2009. This image and others from that Fly-By are among the best Visible Light images that Cassini will capture of the Region around the so-called "Tiger Stripes" - such as those Fissures that keep spraying icy particles, water vapor and organic compounds -, before the moon's South Polar Region enters Winter darkness for the coming years.
This wide-angle view shows not only Baghdad Sulcus, but also other nearby Fractures. The Lit Terrain seen here is on the Leading hemisphere and Saturn-facing Side of Enceladus.
The South Pole lies in shadow near the bottom middle of the image.
The wide-angle view was acquired at a distance of approx. 2000 Km (such as about 1200 miles) from Enceladus and at a Sun-Enceladus-Spacecraft, or Phase, Angle of 114°.
Scale in the wide-angle view is approx. 116 meters (381 feet) per pixel".MareKromium
