(07/19/1997) --- Jet Propulsion Laboratory (JPL) employees Norm Schwartz, at left, and George Nakatsukasa transfer one of three radioisotope thermoelectric generators (RTGs) to be used on the Cassini spacecraft from the installation cart to a lift fixture in preparation for returning the power unit to storage. The three RTGs underwent mechanical and electrical verification testing in the Payload Hazardous Servicing Facility. The RTGs will provide electrical power to Cassini on its 6.7-year trip to the Saturnian system and during its four-year mission at Saturn. RTGs use heat from the natural decay of plutonium to generate electric power. The generators enable spacecraft to operate at great distances from the Sun where solar power systems are not feasible. The Cassini mission is targeted for an Oct. 6 launch aboard a Titan IVB/Centaur expendable launch vehicle. Cassini is built and managed by JPL
