Many studies have been conducted to develp a thermal control system that can operate under the extreme thermal environments found on the lunar surface.While these proposed heat rejection systems use different methods to reject heat,each system contains a similar component,a thermal radiator system.These studies have always considered pristine thermal control system compounds and have overlooked the possible deletrious effects of lunar dust contamination.Since lunar dust has a high emissivity and absorptivity (greater than 0.9) and is opaque,dust accumulation on a surface should radically alter its optical properties and therefore alter its thermal response compared ideal conditions.In addition,the non-specular nature of the dust particles will may alter the performance of systems that employ specular surfaces to enhance heat rejection.
