The Cassini spacecraft is the first to explore Saturn, its rings and its moons from orbit. It was launched in 1997 and arrived in orbit around Saturn seven years later. It was a long journey.
Cassini carried the European Space Agency's Huygens Probe all the way from Earth and on arrival launched it into Titan's thick atmosphere. Now instruments on both spacecraft are providing scientists with vital data and the best views ever of this mysterious, vast region of our solar system.
