Saturn-PIA09795.jpgObscure Planet, Bright Moons... (IR)56 visiteCaption NASA:"Just before Rhea slipped behind Saturn, the Cassini Spacecraft captured the moon in its disappearing act.
Along with the partly obscured Rhea are Tethys, at right, and Enceladus, left of Tethys.
At the wavelength in which this image was taken, absorption of Sunlight by Methane gas in Saturn's Atmosphere is strong, causing the Planet to appear darker than at other wavelengths.
This view looks toward the unilluminated side of the Rings from about 4° above the Ring-Plane. The image was taken with the Cassini spacecraft wide-angle camera on Nov. 9, 2007 using a spectral filter sensitive to wavelengths of Infrared Light centered at 890 nanometers. The view was acquired at a distance of approx. 2,8 MKM (about 1,7 MMs) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 44°.
Image scale is roughly162 Km (such as about 101 miles) per pixel".MareKromium

PSP_005418_1075_RED_abrowse-01.jpgDistorted Layers in the SPLD (extra-detail mgnf - MULTISPECTRUM; credits: Lunexit)56 visiteThis enhanced image (1,2 Km or 0.7 miles across) shows a section of the South Polar Layered Deposits, which are an accumulation of layers consisting mostly of water ice and dust. Perhaps their closest analog on Earth would be the Ice Caps of Greenland and Antarctica.
This image is particularly interesting because the layers are not flat-lying but rather appear "wavy" (---> ondeggianti).
This appearance could partly be an “illusion” due to erosion after the flat-lying layers were deposited. In that case, the wavy appearance is due to the fact that the layer edges are wavy, going into and out of the plane of the outcrop exposing the layers.
Alternatively, this waviness could be due to deformation of the layers folding caused by flow of the ice.
Here, the flow probably occurred long ago since current temperatures are too low to allow the ice to flow at a significant rate.MareKromium

Dione-PIA09801.jpgWhite Scars...56 visiteCaption NASA:"The Cassini spacecraft catches a glimpse of the bright fractures that adorn the Trailing Side of icy Dione.
North on Dione (1126 kilometers, or about 700 miles across) is up.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Nov. 18, 2007. The view was obtained at a distance of approx. 1 MKM (such as about 623.000 miles) from Dione and at a Sun-Dione-spacecraft, or phase, angle of 45°.
Image scale is roughly 6 Km (about 4 miles) per pixel".MareKromium

Dione-N00098970.jpgDione is missing a piece...56 visiteCaption NASA:"N00098970.jpg was taken on December 19, 2007 and received on Earth December 20, 2007. The camera was pointing toward DIONE that, at the time, was approximately 243.552 Km away, and the image was taken using the P60 and UV3 filters.
This image has not been validated or calibrated".MareKromium
