Cassini Unveils Colorful Cratered Calypso
Pasadena CA (JPL) Nov 18, 2005 This color image provides the best look yet at Saturn's moon Calypso, a Trojan (trailing moon) of the larger moon Tethys. Calypso trails Tethys in its orbit by 60 degrees. Telesto is the other Tethys Trojan, orbiting Saturn 60 degrees ahead of Tethys. Calypso is 22 kilometers (14 miles) across. Calypso, like many other small Saturnian moons 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 to also have 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 spacecraft 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.

Prime Time For Rhea Pasadena CA (JPL) Nov 18, 2005 This map of the surface of Saturn's moon, Rhea, illustrates the regions that will be imaged by Cassini during the spacecraft's close flyby of the moon on Nov. 26, 2005. At closest approach, the spacecraft is expected to pass approximately 500 kilometers (310 miles) above the moon's surface. |
