Enceladus Oct. 9, 2008 Flyby41 visteCaption NASA:"This image was taken during Cassini's extremely close encounter with Enceladus on Oct. 9, 2008.
The image was taken with the Cassini Spacecraft narrow-angle camera on Oct. 9, 2008, a distance of approx. 40.000 Km (such as about 25.000 miles) from Enceladus.
Image scale is approx. 477 meters (1566 feet) per pixel".

Unusually-looking "Object" in the Space of Saturn33 visteSi tratta, senza dubbio (!), di una delle tantissime Lune Saturniane, ma quale? Scherzi ed ironie a parte, l'Oggetto Anomalo che Vi proponiamo appare solo in un frame, ottenuto dalla distanza di 433.941 Km dall'Anello "F" di Saturno.
Nel frame successivo (distanza 433.359 Km) e nel frame precedente (distanza 434.224 Km dal Main Target) nulla appare nella porzione alta dell'inquadratura.
L'Oggetto Anomalo, come l'edm ci mostra, possiede una forma piuttosto allungata ed irregolare (e attenzione: l'irregolaritā del Corpo Celeste NON E' stata creata, ma solo ACCENTUATA dalla circostanza per cui il frame č leggermente "mosso") e la sua albedo ci sembra alquanto alta.
Non si distinguono (o almeno: noi non riusciamo a distinguere) rilievi superficiali idonei a consentirci l'identificazione dell'Oggetto, ma la nostra sensazione č che POTREBBE trattarsi della Luna Saturniana "Hyperion" (la quale, in determinate inquadrature, pare effettivamente assomigliare ad una sorta di "oliva" - un pā raggrinzita).
Ad ogni modo, questo frame č indubbiamente interessante e meriterebbe qualche approfondimento...

Northern Craters of Enceladus (natural colors; credits: Lunexit)36 visteCaption NASA:"This image is part of an observation designed to view the moon's plume of icy particles at a moderately High Phase Angle.
The "Phase Angle" is the angle formed between the Sun, the target being imaged, and the Spacecraft, and it ranges from 0 to 180°. Tiny particles, like those in the plume, brighten substantially at high phase angles.
This view was taken from a vantage point 37° above the Equator of Enceladus (about 504 Km, or approx. 313 miles across). Reflected light from Saturn dimly illuminates the moon's dark side.
The image was taken in visible light with the Cassini Spacecraft narrow-angle camera on Sept. 17, 2008. The view was acquired at a distance of approx. 262.000 Km (such as about 163.000 miles) from Enceladus and at a Phase Angle of 140°.
Image scale is roughly 2 Km (5137 feet) per pixel".

Looking for Clouds... (IR - natural - but enhanced - colors; credits: Lunexit)77 visteCaption NASA:"The Cassini Spacecraft peeks through the murk of Titan's thick atmosphere in a search for clouds. Although there are no obvious cloud features in this view, bright cloud streaks have occasionally been seen by Cassini and Earth-based telescopes in the region seen here toward the bottom of Titan's disk. Repeated monitoring observations like this one help scientists build an understanding of Titan's weather and the various climate processes operating on this frigid, but remarkably Earth-like moon.
This view looks toward the Saturn-facing Side of Titan (5150 kilometers, or 3200 miles across). North is up and rotated 35° to the left.
The image was taken with the Cassini Spacecraft narrow-angle camera on Sept. 25, 2008 using a spectral filter sensitive to wavelengths of Infrared Light centered at 938 nanometers. The view was acquired at a distance of approx. 1,7 MKM (such as about 1 MMs) from Titan.
Image scale is roughly 10 Km (approx. 6 miles) per pixel".

Another UFO in the Space of Saturn?22 visteCaption NASA:"N00124205.jpg was taken on November 16, 2008 and received on Earth November 17, 2008. The camera was pointing toward SATURN-RINGS which, at the time, were approximately 382.907 Km away, and the image was taken using the CL1 and CL2 filters. This image has not been validated or calibrated".

Baghdad Sulcus40 visteCaption NASA:"Like hunters sighting a clay duck flying fast in the sky, this mosaic of Cassini images was made from 'skeet shoot' narrow-angle images 1, 2, 3 and 4, all captured during the Oct. 31, 2008, flyby of Saturn's moon Enceladus.
The resolution of this mosaic is 12,3 meters (41 feet) per pixel and jet source VI (see also PIA08385) is identified in the upper right".

Baghdad Sulcus43 visteCaption NASA:"This Cassini image was the ninth 'skeet shoot' narrow-angle image captured during the Oct. 31, 2008 flyby of Saturn's moon Enceladus.
The source region for jet VII (see PIA08385) has been identified. The image was taken with the Cassini Spacecraft narrow-angle camera on Oct. 31, 2008, at a distance of approximately 6151 Km (about 3844 miles) from Enceladus and at a Sun-Enceladus-Spacecraft, or Phase, Angle of 75°.
Image scale is roughly 35 meters (115 feet) per pixel".

Damascus Sulcus58 visteCaption NASA:"This Cassini image was the eight 'skeet shoot' narrow-angle image captured during the October 31, 2008, flyby of Saturn's moon Enceladus.
The source region for jets II and III (see PIA08385) has been identified. The image was taken with the Cassini Spacecraft narrow-angle camera on Oct. 31, 2008, at a distance of approximately 5568 Km (about 3480 miles) from Enceladus and at a Sun-Enceladus-Spacecraft, or Phase, Angle of 75°.
Image scale is roughly 33 meters (108 feet) per pixel".

The Enceladus' "Tiger Stripes"27 visteCaption NASA:"This Cassini image was the first and highest resolution 'skeet shoot' narrow-angle image captured during the Oct. 31, 2008, flyby of Saturn's moon Enceladus.
The image was taken with the Cassini Spacecraft narrow-angle camera on Oct. 31, 2008, at a distance of approximately 1691 Km (about 1056 miles) from Enceladus and at a Sun-Enceladus-Spacecraft, or Phase, Angle of 78°.
Image scale is roghly 9 meters (29 feet) per pixel.
