Pioneer 10 technology breakdown

Pioneer_10

Powered by a lump of plutonium-238 isotope inside four radioisotope thermoelectric generators, Pioneer 10 should have been at just under 80 per cent when communication was lost in 2003, due to rapid deterioration of several key electrical points on the craft. It powered a load-out that included instruments for gathering and sometimes processing raw data from deep space to be sent back to Earth.
