The Cassini spacecraft carries three radioisotope thermoelectric generators. Where can I find information about them?
You’ll find what you are looking for at http://saturn.jpl.nasa.gov/spacecraft/safety/. The quick fact sheet in the “Cassini Launch” press kit has information on the RTGs, and there is more information at the end of the document. Also check “Spacecraft Power for Cassini,” which is listed under “Other Fact Sheets” on the same web page.
