Dione-PIA07691.jpgDione's faulted surface (HR - enhanced colors)56 visiteCaption originale:"(...) To create this enhanced-color view, ultraviolet, green and infrared images were combined into a single black and white picture that isolates and maps regional color differences. This "color map" was then superposed over a clear-filter image.
The origin of the color differences is not yet understood, but may be caused by subtle differences in the surface composition or the sizes of grains making up the icy soil.
Even this view looks toward the Leading Hemisphere on Dione. North is up and rotated 20° to the right.
All the images were acquired with the Cassini spacecraft narrow-angle camera on Dec. 24, 2005 at a distance of approximately 151.000 Km(about 94.000 miles) from Dione and at a phase angle of 99°.
Image scale is approx. 896 mt (about 2.940 feet) per pixel".

Tethys-PIA07698.jpgSmiling Tethys...56 visiteCaption originale:"The profile of Ithaca Chasma forms a great scar in the icy crescent of Tethys. The chasm stretches more than a 1.000 Km (about 620 miles) over Tethys' surface, from North to South.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Dec. 25, 2005 at a distance of approximately 313.000 Km (about 195.000 miles) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 151°. Image scale is about 2 Km (approx. 1 mile) per pixel".

Phoebe.jpgPhoebe (Original NASA/JPL/ASU b/w Image-Mosaic)56 visiteWas Saturn's moon Phoebe once a comet? Images from the Cassini spacecraft taken two years ago (early 2004) when entering the neighborhood of Saturn, indicate that Phoebe may have originated in the outer Solar System.
Phoebe's irregular surface, retrograde orbit, unusually dark surface, assortment of large and small craters, and low average density appear consistent with the hypothesis that Phoebe was once part of the Kuiper Belt of icy comets beyond Neptune before being captured by Saturn. Visible in the above image of Phoebe are craters, streaks, and layered deposits of light and dark material. The image was taken from around 30.000 Km out from this 200-Km diameter moon.
Two weeks after taking the above image, Cassini fired its engines to decelerate into orbit around Saturn.

SaturnStorm-PIA07789.jpgTurbulence... - detail mgnf (2)56 visiteNo lightning flashes are visible in the image (they would look like medium-sized bright spots, since the light would spread out before it reaches the cloud tops), but non-detection does not mean that lightnings are absent, however. Lightning might be too faint to stand out above background or too deep to be seen through the thick clouds. Bad luck is another possibility: the camera might have missed the strong flashes during the 10' that the shutter was open. A narrow-cloud band crosses the storm from left to right. It is illuminated by the Rings from the North and is brighter on that side. Cassini scientists are looking forward to an extensive Night Side image set, designed to look for lightning. That set will be collected during the first half of 2006.
The view was obtained in visible light with the Cassini spacecraft narrow-angle camera at a distance of approx. 3,5 MKM (about 2,2 MMs) from Saturn. The image scale is approx. 20 Km (about 12 miles) per pixel.
