Saturn Case For The Ipad

This captivating natural color view was created from images collected shortly after Cassini began its extended Equinox Mission in July 2008. The mosaic combines 30 images--10 each of red, green and blue light—taken over the course of approximately two hours as Cassini panned its wide-angle camera across the entire planet and ring system on July 23, 2008, from a southerly elevation of 6 degrees. Cassini captured these images at a distance of approximately 690,000 miles (1.1 million kilometers) from Saturn and at a sun-Saturn-spacecraft, or phase, angle of 20 degrees. Cassini has been orbiting Saturn for five Earth years as of June 30, 2009. That's about one sixth of a Saturnian year, enough time for the spacecraft to have observed seasonal changes in the planet, its moons and sunlight's angle on the dramatic rings.
