After a seven-year trip, the Cassini spacecraft arrived at Saturn in July 2004. Since then, Cassini has been capturing never-before-seen imagery of the ringed planet and its moons. By the mission’s end in July 2008, the craft will have made 70 orbits of the Saturnian system, using cameras, magnetometers, spectrometers, and radio antennas to analyze the planet’s magnetic field, composition, rings, atmosphere, and 33 moons more completely than ever before.
