Rhea-PIA11630.jpgCrescent Rhea57 visiteCaption NASA:"The Cassini Spacecraft looks toward the battered Surface of the moon Rhea.
This view looks toward the Leading Hemisphere of Rhea. North on Rhea is up.
The image was taken in Visible Light with the Cassini Spacecraft wide-angle camera on Oct. 13, 2009. The view was acquired at a distance of approx. 44.000 Km (about 27.000 miles) from Rhea and at a Sun-Rhea-Spacecraft, or Phase, Angle of 103°.
Image scale is roughly 3 Km (a little less than 2 miles) per pixel".MareKromium

Rhea-N00146883_to_938-MF.jpgRhea (Image-Mosaic and Natural Colors; credits: Dr M. Faccin)57 visiteE questo image-mosaic, infine, oltre che ai Ragazzi di Pasadena ed allo Space Science Institute, lo dedichiamo anche ai Curatori della prestigiosa Rubrica "NASA - Picture of the Day" (caso mai avessero voglia di pubblicare qualcosa di VERAMENTE spettacolare, eseguito a Regola d'Arte e, soprattutto, di grandissimo valore tecnico e didattico).
Grandissimi Complimenti a Marco Faccin e Gianluigi Barca per i loro grandissimi sforzi (questo mosaico è costato poco più di due ore di lavoro), i quali vengono SEMPRE coronati da - a dire poco - grandissimi risultati (ancorchè detti risultati sono conosciuti e riconosciuti, purtroppo, solo da pochissimi...).MareKromium

Japetus-PIA11632.jpgCrescent Japetus57 visiteCaption NASA:"Japetus shows off its puzzling light and Dark Terrain.
Scientists continue to investigate the nature of this moon's Surface. Lit Terrain seen here is on the Saturn-facing side of Japetus. North on Japetus is up and rotated 8° to the left. Scale in the original image was approx. 7 Km (about 4,5 miles) per pixel. The image has been magnified by a factor of 2 and contrast-enhanced to aid visibility.
The image was taken in Visible Light with the Cassini Spacecraft narrow-angle camera on Sept. 13, 2009. The view was obtained at a distance of approx. 1,2 MKM (such as about 746.000 miles) from Japetus and at a Sun-Japetus-Spacecraft, or Phase, Angle of 103°".MareKromium

TheRings-PIA11635.jpgAegaeon and the G-Ring57 visiteCaption NASA:"The bright arc within Saturn's G-Ring is shown truncated by the shadow of the Planet at the bottom of this image.
Although it can't be seen here, the tiny moonlet Aegaeon (formerly known as S/2008 S 1) orbits within the bright arc.
This view looks toward the northern, sunlit side of the Rings from about 4° above the Ring-Plane. Many background stars are visible elongated by the motion of the Spacecraft during the image's exposure.
The image was taken in Visible Light with the Cassini Spacecraft narrow-angle camera on Oct. 9, 2009. The view was obtained at a distance of approx. 2,1 MKM (about 1,3 MMs) from Saturn. Image scale is roughly 12 Km (a little more than 7 miles) per pixel".MareKromium

Prometheus-091227-N00148969-EB.jpgPrometheus adrift... (possible Natural Colors; credits: Elisabetta Bonora - Lunexit Team)57 visiteNulla di artefatto o manipolato digitalmente, in questo frame prodotto dalla nostra Elisabetta Bonora!
La colorazione rosacea di Prometheus, infatti, potrebbe e dovrebbe dipendere, a nostro modo di vedere, dal Saturnshine (o "Chiaro di Saturno").
E non è neppure inutile rammentare che Prometheus non è la sola Luna Saturniana ad avere un colore simile!
Esso, infatti, forma uno splendido "Space Duo" con Hyperion la cui Superficie, sempre secondo la NASA (e ad eccezione di quanto contenuto nei bizzarri crateri che lo ricoprono quasi per intero), sarebbe di color rosa pallido, con sfumature grigie e bianco/verdastre.MareKromium

Enceladus-PIA12517.jpgA "Pearl of Ice", in the Night of Saturn (possible Natural Colors; credits: Dr Paolo C. Fienga - Lunexit Team)57 visiteCaption NASA:"The Cassini Spacecraft looks toward the South Pole of Enceladus, with a glimpse of Saturns Rings in the distance, during the Spacecraft's close Fly-By of Nov. 2, 2009.
(see PIA08386 to learn more about the active South Pole of Enceladus)
This view looks toward the anti-Saturn side of Enceladus. The Rings have been brightened relative to Enceladus to increase visibility.
The image was taken in Visible Light with the Cassini Spacecraft wide-angle camera on Nov. 2, 2009. The view was acquired at a distance of approx. 10.400 Km (aout 6500 miles) from Enceladus and at a Sun-Enceladus-Spacecraft, or Phase, Angle of 6°.
Image scale is roughly 630 meters (2100 feet) per pixel".MareKromium
