DEUTSCH: Calypso umkreist Saturn auf derselben Bahn wie Tethys, allerdings um 60° hinter dem großen Mond. Die Aufnahme vom 23.09.2005 (Orbit 15) hat eine Auflösung von 600 m/pxl.|
ENGLISH: This color image provides the best look yet at Tethys’ Trojan moon Calypso. Calypso (22 kilometers, 14 miles across) trails Tethys in its orbit by 60 degrees. Telesto is the other Tethys Trojan, orbiting Saturn 60 degrees ahead of Tethys. Calypso, like many other small Saturnian satellites and small asteroids, is irregularly shaped by overlapping large craters. Although the resolution here is not as high as in Cassini’s best images of Pandora and Telesto, this moon appears also to have regolith (loose surface material) capable of smoothing the appearance of craters. Images taken using ultraviolet, green and infrared spectral filters were combined to create this false-color view. The images were taken with the Cassini narrow-angle camera on Sept. 23, 2005, at a distance of approximately 101,000 kilometers (63,000 miles) from Calypso and at a Sun-Calypso-spacecraft, or phase, angle of 61 degrees. Resolution in the original image was 602 meters (1,976 feet) per pixel. The image has been contrast-enhanced and magnified by a factor of three to aid visibility.
