A conceptual venus rover mission using advanced radioisotope power system

The primary goal of this study is to examine the feasibility of using the novel Advanced RPS-driven Stirling thermoacoustic system to enable extended science operations in the extremely hostile surface environment of Venus. The mission concept entails landing a rover onto the Venus surface, conducting science measurements in different areas on the surface, and returning the science data to Earth. The study focused on developing a rover design to satisfy the science goals with the capability to operate for 60 days. This mission life influences several design parameters, including Earth elevation angle and the maximum communications range to Earth.

Dynamic Radioisotope Power Systems: Convertor Development at NASA GRC

NASA's dynamic power convertor development in support of high-efficiency RPS is progressing as planned, and shows promise. This presentation gives dynamic conversion power system background, development path, and key convertor performance goals. It also gives information on the Flexure Isotope Stirling Convertor, Turbo-Brayton Convertor, Thermo-Acoustic Power Convertor, Sunpower Robust Stirling Convertor, Stirling Convertor Extended Operation, TDC #14 Disassembly and Inspection, and Launch Vibration Exposure on SES #2.

Enabling exploration with small radioisotope power systems

The purpose of this report is to provide an initial reference document to support further definition of science community needs for small-RPS flight systems. It describes the most recent results of the ongoing NASA/DOE studies, and provides information for review by potential users that might take advantage of these types of power systems. This is extremely important since any future decision to proceed with the development of such units will require a strong identified need from the space science community and a well-defined set of power and operational requirements. NASA and DOE intend to use this document as a basis for soliciting information on additional small-RPS-enabled mission concepts, along with their respective power and operational requirements. This report is a first step in fleshing out a roadmap for potential future development and acquisition.
