Many Cassini views of Tethys

Many Cassini views of Tethys
Many Cassini views of Tethys This montage presents just a few of the views of Tethys, Saturn's fifth largest moon, that have been captured by Cassini since its arrival. One prominent feature on Tethys is gigantic double-ringed impact basin called Odysseus; it is brought into relief in the second and third images in the second row of this montage. Tethys also has a backwards-"S"-shaped canyon system called Ithaca Chasma that curves around half of the moon. Another recognizable feature is a "T" shape made by five craters. These are clearest in the lower left image. Three craters make a vertical line: Phemius, Polyphemus, and Ajax. To the west of Polyphemus are two more: Arete and an unnamed crater. To the east of this "T" is a larger flat-floored crater, Penelope. Some of these images are public releases from the Cassini imaging team, while others have been composed from raw images by enthusiasts Gordan Ugarkovic and Orion.
