Description
Within the frame of future lunar missions, the evaluation of the change in the performance of representative covering materials is required to estimate the effect of particulate contamination induced by the dust coverage over time (natural or man-induced).
This paper reports on the existing large set of data on the effect of LHS-1 & LHS1-25A deposits (LDS from Space Ressource Technologies) on thermo-optical properties of more than 20 different materials (Coverglasses, Optical Solar Reflectors, Second Surface Mirrors, white and black paintings, MLI outer layers…). Trends of properties versus percentage of dust coverage are available and a metric is proposed to link dust coverage to degradation of solar absorptance and emissivity for all tested material families.
