Enceladus-N00085267.jpgEnceladus (2) - (natural colors - elab. Lunexit)54 visiteCaption NASA:"N00085267.jpg was taken on June 28, 2007 and received on Earth June 29, 2007. The camera was pointing toward Enceladus that, at the time, was approx. 293.113 Km away. The image was taken using the CL1 and IR1 filters.
This image has not been validated or calibrated".MareKromium

Saturn-PIA08973.jpgIR Saturn54 visiteCaption NASA:"Cassini looks toward Northern Latitudes on Saturn and out across the Ring-Plane.
This InfraRed (IR) view probes clouds beneath the hazes that obscure the Planet's depths in natural color views.
This image looks toward the unilluminated side of the Rings from about 24° above the Ring-Plane. The Rings' shadow drapes across the region North of the Planet's bright Equatorial Band.
The image was taken with the Cassini spacecraft wide-angle camera using a spectral filter sensitive to wavelengths of light centered at 890 nanometers. The view was acquired on May 24, 2007 at a distance of approx. 1,5 MKM (such as about 1 MMs) from Saturn.
Image scale is roughly 89 Km (55 miles) per pixel".MareKromium

Enceladus-N00085404.jpgEnceladus (natural colors - elab. Lunexit)54 visiteCaption NASA:"N00085404.jpg was taken on June 28, 2007 and received on Earth June 29, 2007. The camera was pointing toward Enceladus that, at the time, was approx. 293.794 Km away.
This image was taken using the BL1 and CL2 filters and it has not been validated or calibrated".MareKromium

Hyperion-PIA09216.jpgCold Hyperion...54 visiteCaption NASA:"In this ultraviolet image of Hyperion, produced using data taken with Cassini's Ultraviolet Imaging Spectrograph during the September 2005 close flyby, brightness contrasts are due to both topographic and compositional variations across the surface. The brightest regions are exposed water ice in the rim of the crater that dominates the hemisphere in view.
This new ultraviolet map (left) is shown next to a previously released image (right) taken by the Imaging Science Subsystem".MareKromium

Hyperion-PIA09215.jpgWhat's all over Hyperion? (extra-detail mgnf)54 visiteCaption NASA:"This is a color map of the composition of a portion of Saturn's moon Hyperion's surface about 75 Km (approx. 45 miles) on a side.
In this map, blue shows the maximum exposure of Frozen Water (H2O), red denotes Carbon Dioxide (CO2) ice ("dry ice"), magenta indicates regions of Water plus CO2, yellow is a mix of CO2 and an unidentified material.
This map was made with data from the Visual and Infrared Mapping Spectrometer aboard the Cassini spacecraft during its flyby of Hyperion in September 2005".MareKromium

Saturn-PIA08983.jpgSpokes!54 visiteCaption NASA:"The Cassini Spacecraft spies multiple spokes in Saturn's outer B-Ring. The precise origin and evolution of these transient features continue to provide Ring Scientists with intriguing puzzles to solve.
Most of these spokes are about 4000 Km long; the 2 near the bottom of the scene are about 1000 Km (about 600 miles) wide.
This view looks toward the unilluminated side of the Rings from about 8° above the Ring-Plane.
The image was taken in visible green light with the Cassini spacecraft narrow-angle camera on June 2, 2007. The view was acquired at a distance of approx. 2,2 MKM (such as about 1,4 MMs) from Saturn.
Image scale is roughly 13 Km (about 8 miles) per pixel".MareKromium

Saturn-PIA08987.jpgNorthern Latitudes54 visiteCaption NASA:"Incredible swirling details in Saturn's Northern Clouds can be seen in this dazzling view. Shadows cast by the Rings embrace the Northern Hemisphere.
The view looks toward the unilluminated side of the Rings from about 16° above the Ring-Plane.
The image was taken with the Cassini spacecraft wide-angle camera on June 10, 2007 using a spectral filter sensitive to wavelengths of infrared light centered at 939 nanometers. The view was acquired at a distance of approx. 1,3 MKM (such as about 800.000 miles) from Saturn. Image scale is roughly 72 Km (about 45 miles) per pixel".MareKromium
