ColdWetDog (752185) writes "A brief note in the Atlantic notes that Congress has failed to supply funds to continue Plutonium-238 production, needed for radioisotope generators for NASA's interplanetary probe programs. No PU-238 means no more missions like Cassini-Huygens and pretty much anywhere that the sun doesn't shine enough to power the satellite via solar cells.
The article notes that the only other source of PU-238 is Russia — either through the government or through trolling through Siberia and the Russian coastline looking for old Soviet Era lighthouses and power stations." Link to Original Source
