Abstract
The harsh space environment induces changes in optical signature of spacecraft polymeric materials which can occur due to surface degradation, leading to altered reflectivity, or due to radiation induced chemical modification, leading to an alteration of a material’s absorption/transmission. The optical character of commonly used materials change continuously under exposure to high energy electrons, a primary damaging species in geostationary Earth orbit (GEO). In this study we employed directional hemispherical reflectance (DHR) measurements to study the evolution of optical properties of several electron-irradiated PI materials during irradiation with high energy electrons. In particular, we present DHR spectra and the astronomical color index of chosen materials as a function of electron fluence to assist the spacecraft designers to understand each material’s value as a thermal control surface as a function of GEO exposure.
