Extended operation of exploratory systems on the surface of planets like Venus, means that techniques to cool system electronics to essentially room temperature (30ºC) while the ambient temperature is over 470ºC must be developed and demonstrated. This proposal discloses a patent-pending passive thermal management system (TMS) capable of providing electronic system cooling at 30ºC, while rejecting heat to ambient temperatures above 500ºC. This Phase I effort includes performance demonstration experiments in a representative thermal environment. These experiments will demonstrate a TMS system with a system mass of less than 0.22 kg/W/day, that provides passive isothermal temperature control, with no moving parts.
