Tethys-PIA06140-N-HD.jpgTethys in natural colors (HD)56 visiteCommento NASA originale estratto da "NASA - Picture of the Day" del 29 Novembre 2004:"Tethys is one of the larger and closer moons of Saturn. The Cassini spacecraft now orbiting Saturn passed near the frozen moon at the end of October, capturing the most detailed images since the Voyager spacecrafts in the early 1980s. Tethys is composed almost completely of water ice and shows a large impact crater that nearly circles the planet. Because this crater did not disrupt the moon, Tethys is hypothesized to be at least partly liquid in its past. Two smaller moons, Telesto and Calypso, orbit Saturn just ahead of and behind Tethys. Giovanni Cassini discovered Tethys in 1684. The Cassini spacecraft is scheduled for a close fly-by of Tethys in September 2005".

Tethys-PIA06140_modest.jpgTethys in natural colors57 visiteCaption NASA originale:"Having passed closer to Tethys than the Voyager 2 spacecraft, Cassini has returned the best-ever natural color view of this icy Saturnian moon.
As seen here, the battered surface of Tethys has a neutral hue. The image here is a mosaic of two footprints. Three images taken in the red, green and blue filters were taken to form a natural color composite. The result reveals a world nearly saturated with craters - many small craters lie on top of older, larger ones, suggesting an ancient surface. At the top and along the boundary between day and night, the moon's terrain has a grooved appearance.
This moon is known to have a density very close to that of water, indicating it is likely composed mainly of water ice. Its frozen mysteries await Cassini's planned close flyby in September 2005".

Tethys-PIA06518_modest.jpgTethys from approx. 7.900.000 Km53 visiteCaption NASA originale: "Two large craters and hints of several smaller ones are visible in this Cassini image of Saturn's icy moon Tethys (1060 Km across).
The image was taken in visible light with the Cassini spacecraft narrow angle camera on Sept. 23, 2004, at a distance of 7.9 MKMs from Tethys and at a Sun- Tethys-spacecraft, or phase, angle of 80°. The image scale is 48 Km per pixel. The image has been contrast-enhanced and magnified by a factor of four to aid visibility".
