(07/18/1997) --- Jet Propulsion Laboratory (JPL) workers Dan Maynard and John Shuping prepare to install a radioisotope thermoelectric generator (RTG) on the Cassini spacecraft in the Payload Hazardous Servicing Facility (PHSF). The three RTGs which will provide electrical power to Cassini on its mission to the Saturnian system are undergoing mechanical and electrical verification testing in the PHSF. RTGs use heat from the natural decay of plutonium to generate electric power. The generators enable spacecraft to operate far from the Sun where solar power systems are not feasible. The Cassini mission is scheduled for an Oct. 6 launch aboard a Titan IVB/Centaur expendable launch vehicle. Cassini is built and managed for NASA by JPL
