Abstract
Radioisotope thermoelectric generators (RTG) will likely be required for interplanetary CubeSat missions to the outer planets due to reduced solar flux – for example, approximately 1% at Saturn compared to that available at Earth. We present preliminary design work for PocketRTG – a 0.5U sized RTG using commercial off the shelf (COTS) Strontium-90 fuel designed to generate approximately 50mW.
