Abstract	NASA’s Advanced Program and Integration Office (APIO) established two teams (the Strategic and Capability Roadmap Teams) to perform roadmapping activities. The final recommendation will be established by the middle of the next fiscal year, with inputs from the various disciplines within NASA and from outside advisory groups. These groups include the Mars Exploration Program Assessment Group (MEPAG), the Outer Planets Advisory Group (OPAG), the Solar System Exploration Subcommittee (SSES), with recommendations by the National Academies reported in the 2003 Decadal Survey. Both NASA and the science community recognized Radioisotope Power Systems (RPS) as an important enabling technology for our space exploration efforts. Currently two RPSs are under development by NASA, DoE and several industry partners. Both systems are designed to generate >110We at BOL. The MMRTG with static power conversion was down selected for the Mars Science Laboratory mission, while the SRG with dynamic power conversion could be envisioned for Lunar mission as early as the first years of the next decade. In addition, NASA and DoE is considering the development of small-RPSs in the 10s to 100s of milliwatts and 10s of watts power ranges, respectively. These RPSs would be ideally suited for solar system exploration missions, where the spacecraft must operate for a long duration, measured in years, independently from solar availability.
