Venus surface power and cooling systems

Geoffrey A. Landis, Kenneth C. Mellott
2007 Acta Astronautica  
Power and cooling systems were analyzed for Venus surface operation. A radioisotope power and cooling system was designed to provide electrical power for a probe operating on the surface of Venus.  ...  A mission to the surface of Venus would have high scientific value, but most electronic devices and sensors cannot operate at the 450 • C ambient surface temperature of Venus.  ...  A project like this is the sum of the work of a large number of people, and we would like to thank all the participants in the project.  ...
