Technical ReportAbstract
Thermal control of life-support, power electronics, and other systems is a key enabler for a variety of
NASA space, air-flight, and monitoring technologies and is the topic of this research. An example system
requiring advanced thermal control is the Surface Water Ocean Topography (SWOT) project, which is
designed to acquire precise measurements of land hydrology and ocean circulation. The resulting data will
help generate a global assessment of surface water resources and detailed ocean process mapping that will
ultimately be used for climate modeling. SWOT’s instruments have relatively high electronic heat dissipation (~1 kW) and must be co-located with other components. However, the instrument temperatures
must be extremely stable, with a rate of change below 0.05 K/minute. Furthermore, this must be
accomplished in low-Earth orbit, where the variations of solar insolation and Earth reflectance and emission
are large. To put this challenge in perspective, typical spacecraft instruments have temperature stability
requirements on the order of 1 K/min, usually achieved by isolating components. Lightweight, compact,
low-power and reliable thermal control technologies must be developed and proven to meet these
requirements
