Rhea-PIA11458.jpgRhea (Natural Colors; credits: Lunar Explorer Italia)54 visiteCaption NASA:"The Terminator between light and dark throws Rhea's cratered surface into stark relief while the Southern Hemisphere is scored by bright icy cliffs.
North on Rhea is up and rotated 42° to the right in this 2-tile mosaic. This view looks toward the Leading Hemisphere of Rhea (approx. 1528 Km, or about 949 miles across).
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Feb. 2, 2009. The view was acquired at a distance of approx. 181.000 Km (such as about 112.000 miles) from Rhea and at a Sun-Rhea-Spacecraft, or Phase, Angle of 91°.
Image scale is roughly 1 Km (about 3300 feet) per pixel".MareKromium

Saturn-PIA11461.jpgBlack Shadow from the "White Moon" (Natural Colors; credits: Lunar Explorer Italia)54 visiteCaption NASA:"The shadow of Saturn's moon Enceladus cast onto the Planet's Atmosphere appears like a drop of black ink on a canvas of Saturnian storms.
The image was taken with the Cassini spacecraft narrow-angle camera on June 20, 2008 using a spectral filter sensitive to wavelengths of Near-InfraRed Light centered at 750 nanometers. The view was obtained at a distance of approx. 1,3 MKM (such as about 810.000 miles) from Saturn and at a Sun-Saturn-Spacecraft, or Phase, Angle of 24°.
Image scale is roughly 7 Km (about 4 miles) per pixel".MareKromium

Janus-PIA11469.jpgJanus' Polar Crater54 visiteCaption NASA:"A large crater on Saturn's tiny moon Janus is distinctly visible in this Cassini Spacecraft image. Lit terrain seen here is on the Leading Hemisphere of Janus (approx. 179 Km, or about 111 miles across). North on Janus is up and rotated 7° to the left.
The image was taken in Visible Light with the Cassini Spacecraft narrow-angle camera on March 5, 2009. The view was acquired at a distance of approx. 1,1 MKM (about 684.000 miles) from Janus and at a Sun-Janus-Spacecraft, or Phase, Angle of 53°. Resolution in the original image was roughly 6 Km (about 4 miles) per pixel.
The image has been magnified by a factor of two to aid visibility".MareKromium

Eclipse-N00136236.gifEclipse... (GIF-Movie; credits: Dr G. Barca)54 visiteUno spettacolare GIF-Movie realizzato dal nostro (sempre più bravo) Dr Barca il quale ci mostra una stupenda eclissi mentre si materializza davanti agli "occhi elettronici" dell'Orbiter CASSINI.
Un "commento"? Ecco lo Spazio: l'Ultima Frontiera. La VERA e l'UNICA Ultima Frontiera.MareKromium

Pandora-PIA11499.jpgPandora54 visiteCaption NASA:"The thin shadow of the moon Pandora cuts across Saturn's narrow F-Ring.
As Saturn approaches its August 2009 Equinox, the planet's moons cast shadows onto the Rings. Pandora (about 81 Km, or approx. 50 miles across) is on the left of the image. Other bright points of light in the image are background stars.
This view looks toward the unilluminated side of the Rings from about 55° above the Ring-Plane. The image was taken in Visible Light with the Cassini Spacecraft narrow-angle camera on April 16, 2009. The view was obtained at a distance of approx. 1,3 MKM (such as about 808.000 miles) from Saturn and at a Sun-Saturn-Spacecraft, or Phase, Angle of 98°.
Image scale is roughly 8 Km (about 5 miles) per pixel".MareKromium

Prometheus-PIA11531.jpgPrometheus54 visiteCaption NASA:"The moon Prometheus and a bit of Saturn's Northern Hemisphere are both brilliantly lit by the Sun here, making the A-Ring seem dim in comparison.
The bright limb of Saturn's Northern Hemisphere can be seen through the A-Ring in the lower left of the image.
Prometheus (about 86 Km, or approx. 53 miles across) orbits in the Roche Division between Saturn's A and F-Ring.
For a similar view of Pandora, another of the F-Ring's Shepherding Moons, see PIA09899.
This view looks toward the sunlit side of the Rings, from about 20° below the Ring-Plane.
The image was taken in Red Light with the Cassini Spacecraft narrow-angle camera on May 25, 2009. The view was acquired at a distance of approx. 694,000 Km (about 431.000 miles) from Prometheus and at a Sun-Prometheus-Spacecraft, or Phase, Angle of 49°.
Image scale is roughly 3,6 Km (about 2,2 miles) per pixel".MareKromium

Dione-PIA11532.jpgWispy Dione54 visiteCaption NASA:"The Cassini Spacecraft looks toward the wispy, fractured terrain of the Trailing Hemisphere of the moon Dione.
To learn more about Dione's "Wisps", see also PIA08960.
Lit Terrain seen here is on the Trailing Hemisphere of Dione (about 1123 Km, or approx. 698 miles across). North on Dione is up and rotated 29° to the right.
The image was taken in visible light with the Cassini Spacecraft narrow-angle camera on May 26, 2009. The view was acquired at a distance of approx. 1,3 MKM (about 808.000 miles) from Dione and at a Sun-Dione-Spacecraft, or Phase, Angle of 35°.
Image scale is roughly 8 Km (about 5 miles) per pixel".MareKromium

Janus-PIA11534.jpgCraters on Janus (possible Natural Colors; credits: Lunexit)54 visiteCaption NASA:"From hundreds of thousands of kilometers away, the Cassini Spacecraft spies craters on the Surface of the moon Janus.
This view looks toward the Saturn-facing side of Janus (about 179 Km, or approx. 111 miles across). North on Janus is up and rotated 27° to the right. The image was taken in Green Light with the Cassini Spacecraft narrow-angle camera on May 25, 2009.
Scale in the original image was roughly 4 Km (approx. 2,5 miles) per pixel. The image has been magnified by a factor of two and contrast-enhanced to aid visibility.
The view was acquired from a distance of approx. 730.000 Km (such as about 454.000 miles) from Janus and at a Sun-Janus-Spacecraft, or Phase, Angle of 38°".MareKromium

Rhea-PIA11537.jpgRhea and two "Possible Companions"54 visiteCaption NASA:"A couple of craters share a crescent of Lit Terrain on Saturn's moon Rhea.
Lit Terrain seen here is on the Trailing Hemisphere of Rhea. This view is centered on 48° North Latitude, 234° West Longitude. The North Pole is on the Terminator, about one-quarter of the way inward from the top of the image.
The image was taken in Visible Violet Light with the Cassini Spacecraft narrow-angle camera on June 3, 2009. The view was obtained at a distance of approx. 1,4 MKM (such as about 870.000 miles) from Rhea and at a Sun-Rhea-Spacecraft, or Phase, Angle of 121°.
Image scale is roughly 8 Km (about 5 miles) per pixel".MareKromium

Tethys-N00126733.jpgCrescent Tethys (Natural Colors; credits: Lunexit)54 visiteN00126733.jpg was taken on December 17, 2008 and received on Earth December 17, 2008. The camera was pointing toward TETHYS that, at the time, was approximately 527.571 Km away. This image was taken using the CL1 and CL2 filters and it has not been validated or calibrated.MareKromium

Rhea-PIA11550.jpgRhea (Natural Colors; credits: Lunexit)54 visiteCaption NASA:"The battered features of the moon Rhea, seen at low phase, appear washed out by the Sun.
This view looks toward the Saturn-facing side of Rhea at a Sun-Rhea-Spacecraft, or Phase, Angle of 15°. To see Rhea at an even lower phase angle -- near opposition -- see PIA10542.
North on Rhea is up and rotated 7° to the left.
The image was taken in Visible Light with the Cassini spacecraft narrow-angle camera on May 26, 2009. The view was obtained from a distance of approx. 1,4 MKM (such as about 870.000 miles) from Rhea.
