Janus-PIA10455.jpgJanus' North Polar Regions55 visiteCaption NASA:"On a high-inclination orbit of Saturn, the Cassini Spacecraft gazes down at the North Polar Region of Janus.
This view looks toward Janus (about 179 Km, or approx. 111 miles across) from a perspective 72° North of the moon's Equator. The image was taken with the Cassini Spacecraft narrow-angle camera on July 14, 2008 using a spectral filter sensitive to wavelengths of infrared light centered at 752 nanometers. The view was acquired at a distance of approx. 259.000 Km (about 161.000 miles) from Janus and at a Sun-Janus-Spacecraft, or Phase, Angle of 78°.
Image scale is roughly 2 Km (5085 feet) per pixel".MareKromium

Enceladus-N00118361.jpgThe Unbelievable Surface of Enceladus, from ONLY 545 Km!58 visiteCaption NASA:"Caption NASA:"N00118365.jpg was taken on August 11, 2008 and received on Earth August 12, 2008. The camera was pointing toward ENCELADUS that, at the time, was approximately 545 Km away.
The image was taken using the CL1 and CL2 filters and it has not been validated or calibrated".
Note Lunexit: tutta la Regione ripresa pare essere - letteralmente - un "groviglio" di crepacci e di canali che si intersecano e che evidenziano, sulle loro estremità, l'esistenza di rilievi davvero singolari (alcuni a forma sferoidale, ed altri, molto irregolari, che ci ricordano i "rami contorti" di una sorta di foresta pietrificata). Comune a tutti i rilievi visibili è l'abedo: elevatissima (si tratta forse di grandi "blocchi di ghiaccio"? Probabilmente si).
Un numero elevato di boulders è chiaramente distinguibile sull'intera scena e, in particolare, sul versante illuminato del crepaccio situato nell'angolo superiore Sx del frame (un crepaccio che, a nostro parere, lascia altresì intuire - se si osserva con estrema attenzione - la presenza di "chiazzature" le quali possono ricordare i "seeps" Marziani).
Un grandissimo frame, reso ancora più straordinario dal fatto che il panorama ripreso giace a ridosso del Terminatore!MareKromium

Dione-PIA09838.jpgDione (MULTISPECTRUM-2; credits: Lunexit)57 visiteCaption NASA:"The Cassini Spacecraft looks down from high latitude over Dione and the system of wispy fractures that coats the moon's Trailing Side.
This view looks toward Dione from 43° above the Equator. North is up.
The image was taken in visible light with the Cassini Spacecraft narrow-angle camera on Jan. 14, 2008. The view was acquired at a distance of approx. 938.000 Km (such as about 583.000 miles) from Dione and at a Sun-Dione-Spacecraft angle of 54°.
Image scale is roughly 6 Km (a little less than 4 miles) per pixel".MareKromium
