Cassini launched
NASA/JPL’s interplanetary probe Cassini, with the European Space Agency-built Huygens Titan probe tagging along, lifts off on a Titan IV-B rocket. The voyage to Saturn will last seven years, during which Cassini does close flybys to receive gravity assists from Venus, Earth, Earth’s moon, and Jupiter en route to Saturn. It will operate in Saturn’s vicinity for over a decade and launch the Huygens probe, the first landing probe to visit a body in the outer solar system.
