| Abstract: | This paper analyzes the plume contamination of the 20 N orbit control thruster of a satellite on its thermal control coatings. Based on the simulation of the thruster plume field and the deposition process,the thickness of molecular deposition on S781 and OSR coatings is calculated in different orbital operation periods and the solar absorptance degradation is evaluated for the thermal control coatings. |

| Keywords: | plume contamination deposition thermal control coatings |
