Abstract
Advanced radioisotope power systems with high specific power (We/kg) are being developed to meet the needs of future NASA science and exploration missions. Technology portfolio includes the development of an advanced thermoelectric converter with a goal of 6 – 8 We/kg specific power and an advanced stirling radioisotope generator with a specific power goal of greater than 7 We/kg. Upon successful technology demonstration, one or both of these technologies have the potential to be transitioned to flight system development for post-2015 missions. In addition, advanced concepts are being developed to establish the feasibility of radioisotope power systems with specific power greater than 10 We/kg for post-2020 missions.
