Tethys Geography Lesson using a new raw image

The Cassini Raw images page has a new raw image of Tethys taken from a distance of 2,581,702 km, yielding a resolution of 15 km/pixel. While low resolution, you can see a number of very large craters on Tethys' trailing hemisphere. At three o'clock, you can see Penelope. Near the center of the disk, you can see three craters, from north to south: Phemius, Polyphemus, and Ajax. Near 6 o'clock, you can see a crater that's a little smaller than Penelope named Antinous. The small crater near the terminator left of the three, north-south craters is called Arete.
