- Enceladus Mosaic from NASA (February 16, 2005)
- original image caption: This spectacular view is a mosaic of four high resolution images taken by the Cassini spacecraft narrow angle camera on Feb. 16, 2005, during its close flyby of Saturn's moon Enceladus. The view is about 300 kilometers (200 miles) across and shows the myriad of faults, fractures, folds, troughs and craters that make this Saturnian satellite especially intriguing to planetary scientists. More than 20 years ago, NASA's Voyager spacecraft gave hints of a surface cut by tectonic features, and subsequent images of other icy moons have revealed many different ways that stresses have acted on icy moon crusts. Because Cassini flew rapidly past Enceladus, the right-side images were taken from a slightly different perspective than the left, and are delineated by the white box. The mosaic covers longitudes from about 254 west to 296 west and latitudes from 60 south to the equator. The images were taken in visible light on Feb. 17, 2005, at distances ranging from of 26,140 to 17,434 kilometers (16,243 to 10,833 miles) from Enceladus and at Sun-Enceladus-spacecraft, or phase, angles ranging from 27 to 29 degrees. Pixel scale in the left-side image is 150 meters (492 feet) per pixel; in the right-side (white box) image, scale is 105 meters (344 feet) per pixel. The image has been contrast-enhanced to aid visibility.
