Abstract

Space telescopes are exposed to extreme hot and cold temperature variations in the space environment depending on their orbit conditions. These temperature variations cause a significant effect on the opto-mechanical structures and lead to the final optical performance degradation. The development of space optical telescopes must achieve a thermally stable and reliable system through thermal analysis for on-orbit temperature prediction and thermal control design maintaining all components within their operating/survival temperature limits during entire mission phases. In this paper, we report the analysis results of passive and active thermal design for the ROKITS mission based on on-orbit thermal analysis taking into account the worst hot and cold conditions in the space environment using thermal analysis program - Thermal Desktop®, SINDA/FLUINT®.
