Telesto

These views show surface features and color variation on the Trojan moon Telesto. The smooth surface of this moon suggests that, like Pandora, it is covered with a mantle of fine, dust-sized icy material.
This monochrome image was taken in visible light. To create the false-color view (see PIA07697), ultraviolet, green and infrared images were combined into a single black and white picture that isolates and maps regional color differences.
The "color map" was then superposed over a clear-filter image. The origin of the color differences is not yet understood, but may be caused by subtle differences in the surface composition or the sizes of grains making up the icy soil.
Tiny Telesto is a mere 24 Km (about 15 miles) wide.

The image was acquired with the Cassini spacecraft narrow-angle camera on Dec. 25, 2005 at a distance of approx. 20.000 Km (about 12.000 miles) from Telesto and at a Sun-Telesto-spacecraft, or phase, angle of 58°. Image scale is 118 meters (387 feet) per pixel.
