PASADENA, UNITED STATES: Simonetta DiPippo, director of the Observation of the Universe for the Italian Space Agency (ASI), sits beside an image of the Saturn's largest moon Titan as she answers questions about the Cassini-Huygens mission to Saturn, during a "Ringside Chat" press conference, 30 June 2004 at the Jet Propulsion Laboratory (JPL) in Pasadena, CA. After nearly seven years of travel from earth, the international mission's spacecraft is due to enter Saturn's orbit later 30 June 2004 to begin a four-year study of the planet, its rings and, later in the year, a landing of the Huygens probe on the surface of Titan.
