Cryothermal Measurements of Variable Emittance Coatings with Optical Heating

The purpose of this experiment is to determine how a variable emittance coating behaves in a cold space environment with constant heating by sunlight and variable internal heating, as well as how tungsten doping affects its performance with lower phase transition temperature ranges. The results of this experiment will show how a variable emittance coating performs under cryostat testing conditions in order to determine its radiative cooling properties. By optimizing the performance of radiative cooling materials, energy originally used to provide thermal control can be preserved.
