NASA'S Cassini spacecraft captures Saturnian moon ballet
June 22, 2006The cold, icy orbs of the Saturn system come to life in a slew of new movie clips showing the ringed planet's moons in motion.
In addition to their drama and visual interest, scientists use these movies to refine their understanding of the orbits of Saturn's moons. Engineers at NASA's Jet Propulsion Laboratory, Pasadena, Calif., use the same images, and the orbital positions of the moons, to help them navigate the Cassini spacecraft, which is nearing the halfway mark of its four-year tour.
Pictures capturing several moons in one frame are often strikingly beautiful, especially when deliberately imaged in red, green and blue spectral filters, which allow scientists to create a color photo. One recent color image shows two of Saturn's most fascinating moons, icy-white Enceladus and orange, haze-enshrouded Titan.
