''Voyager 1'' has three [[radioisotope thermoelectric generator]]s (RTGs) mounted on a boom. Each [[MHW-RTG]] contains 24 pressed [[plutonium-238]] oxide spheres.<ref name="furlong-1999" /> The RTGs generated about 470 [[Watt |W]] of [[electric power]] at the time of launch, with the remainder being dissipated as waste heat.<ref>{{Cite web |title=Spacecraft Lifetime |url=https://voyager.jpl.nasa.gov/spacecraft/spacecraftlife.html |url-status=live |archive-url=https://web.archive.org/web/20170301102317/http://voyager.jpl.nasa.gov/spacecraft/spacecraftlife.html |archive-date=March 1, 2017 |access-date=August 19, 2013 |publisher=JPL}}</ref> The power output of the RTGs declines over time due to the 87.7-year [[half-life]] of the fuel and degradation of the [[thermocouple]]s, but they will continue to support some of its operations until at least 2025.<ref name="jpl-1989" /><ref name="furlong-1999">{{Cite journal |last1=Furlong |first1=Richard R. |last2=Wahlquist |first2=Earl J. |date=1999 |title=U.S. space missions using radioisotope power systems |url=http://www2.ans.org/pubs/magazines/nn/pdfs/1999-4-2.pdf |url-status=dead |journal=Nuclear News |volume=42 |issue=4 |pages=26–34 |archive-url=https://web.archive.org/web/20181016011258/http://www3.ans.org/pubs/magazines/nn/pdfs/1999-4-2.pdf |archive-date=October 16, 2018 |access-date=January 2, 2011}}</ref>
