Microsphere Plutonium-238 Oxide Fuel to Revolutionize New Radioisotope Power Systems and Heat Sources for Planetary Exploration

We propose R&D activities supporting the advancement of improved radioisotope heat sources for future NASA exploration missions such as those to Ocean Worlds. To enable flexible geometries and high volumetric power loadings, microsphere-based heat sources are attractive. R&D would allow a feasibility assessment of microsphere-based heat sources.
