Mimas-N00063438.jpgMimas and Enceladus (2)60 visiteCaption originale:"N00063438.jpg was taken on July 03, 2006 and received on Earth July 04, 2006. The camera was pointing toward Mimas that, at the time, was approximately 1.635.384 Km away. The image was taken using the CL1 and CL2 filters".

Rhea&Dione-PIA08203.jpgRocky Sisters54 visiteTwo Saturnian moons meet in the sky: Dione departs after crossing the face of Rhea for several minutes.
Dione, at right, has a notably smoother-looking surface than Rhea, thus suggesting the former has been modified more recently.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on May 14, 2006 at a distance of approx. 2,7 MKM (such as about 1,7 MMs) from Dione and 3,1 MKM (about 1,9 MMs) from Rhea.
The phase angle is about 134° on both moons, while the image scale is about 16 Km (such as roughly 10 miles) per pixel on Dione and about 18 Km (11 miles) per pixel on Rhea.

Enceladus-PIA08197.jpgIcy Plumes in the Ring-Shine55 visiteCaption NASA originale:"The plumes of Enceladus continue to gush icy particles into Saturn orbit, making this little moon one of a select group of geologically active bodies in the solar system.
Enceladus (505 Km, or 314 miles across) is seen here against the night side of Saturn. The extended exposure time used to image the plumes also makes the Southern Hemisphere, illuminated by Ring-Shine, appear bright.
The image was acquired in visible light with the Cassini spacecraft narrow-angle camera on May 4, 2006 at a distance of approx. 2,1 MKM (about 1,3 MMs) from Enceladus and 2,3 MKM (about 1,5 MMs) from Saturn. The image was taken at a Sun-Enceladus-spacecraft, or phase, angle of 159°. Image scale is roughly 13 Km (such as about 8 miles) per pixel on Enceladus".

Saturn-PIA08191.jpgClouds of Saturn55 visiteCaption NASA originale:"The soft, sweeping shadows of Saturn's C-Ring cover bright patches of clouds in the Planet's Atmosphere. The shadow-throwing rings stretch across the view at bottom.
The dark inner edge of the B-Ring is visible at top.
The image was taken using a spectral filter sensitive to wavelengths of infrared light centered at 752 nanometers. The image was acquired with the Cassini spacecraft wide-angle camera on April 28, 2006 at a distance of approximately 340.000 Km (about 211,000 miles) from Saturn. Image scale is roughly 17 Km (about 10 miles) per pixel".

Saturn-PIA08166.jpgRomantic inhospitality...56 visiteCaption originale:"Dreamy colors ranging from pale rose to butterscotch to sapphire give this utterly inhospitable gas planet a romantic appeal. Shadows of the rings caress the Northern Latitudes whose blue color is presumed to be a seasonal effect.
Enceladus hugs the Ring-Plane right of center.
Images taken using red, green and blue spectral filters were combined to create this color view, which approximates what the human eye would see. The image was taken with the Cassini spacecraft wide-angle camera on March 16, 2006 at a distance of approximately 2,1 MKM (such as about 1,3 MMs) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 102°. Image scale is about 120 Km (approx. 75 miles) per pixel on Saturn".

Tethys&Co-PIA08165.jpgWonderful Trio, in Saturn's Space54 visiteCaption originale:"The three very different moons seen here provide targets of great interest for planetary scientists studying the Saturn System. Captured here by Cassini, along with the Rings, are Tethys at upper right, Enceladus below center and Janus at lower left.
Researchers study the orbital dance of Janus (181 Km, or about 113 miles across) with Epimetheus, tectonics and cratering on Tethys (1.071 Km, or approx. 665 miles across) and geyser activity on Enceladus (505 Km, or about 314 miles across). And these are only a few of the wonders that await exploration in the realm of the Ringed Planet.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on March 16, 2006, at a distance of approx. 2,4 MKM (such as about 1,5 MMs) from Tethys; 1,9 MKM (about 1,2 MMs) from Enceladus and 2,2 MKM (roughly 1,4 MMs) from Janus. The image scale is about 14 Km (appx. 9 miles) per pixel on Tethys, 11 Km (about 7 miles) p. px. on Enceladus and 13 Km (about 8 miles) p. px on Janus".
