Title: SNAP 19 Pioneer and 11 RTG deep space performance

Abstract

Power to conduct experiments and to return the data back to Earth from distances up to and possibly exceeding 1.5 billion miles is furnished to the Pioneer 10 and 11 deep space probes by four SNAP 19 type thermoelectric generators each. The plutonium-fueled power systems produced a nominal 160 watts after launch at a generator conversion efficiency of 6.2 percent. Following five years of flight between the spacecrafts, the primary objectives, successful flyby of Jupiter, have been achieved, and Pioneer 11 was targeted for Saturn. Power system performances have been satisfactory and consistent with predictions which conclude that sufficient power will be available to conduct Saturn experiments in 1979. (auth)
