Space Environmental Testing at GSFC

Abstract

One critical piece of information needed in the thermal design of all spacecraft are the thermal properties of the coatings and the determination of how those properties change due to the space environmental over the lifetime of a spacecraft. At the Goddard Space Flight Center (GSFC) we have the ability to measure the beginning of life (BOL) thermal properties of thermal control coatings such as solar absorptance, emittance as a function of temperature, conductivity and we can also determine how those properties will change over the lifetime of the spacecraft.
