The NASA Advanced Solar Dynamics Technology Program

The NASA Advanced Solar Dynamics Technology Program, aimed at developing power system technology for versatile, advanced, high-capacity spacecraft and surface power systems, is discussed. The goals of the program are to be achieved by pursuing high-risk but high-payoff technologies, namely, advanced solar concentrators, heat receivers, power conversion dynamic cycles, and radiators. The NASA program is discussed in terms of mission drivers, the technological goals for each of the system's major components, and program status.
