Spacecraft Thermal Control
This is a fast-paced two-day course appropriate for System Engineers/Managers with an interest in improving their understanding of spacecraft thermal design or Engineers who want to get an overview of thermal systems engineering process. All phases of thermal design, integration, testing, and in-flight operations are covered in enough depth to give a deeper understanding of the design process. The goals are to have every student understand (1) “bigger picture” system and tradeoff issues (2) thermal analysis, design, thermal devices, thermal testing, and (3) how the thermal design interacts with the overall system design and fits into the overall picture of satellite design. Case studies, lessons learned, and interactive problems, illustrate the importance of thermal design and the current state of the art.

Carol L. Mosier, NASA Emeritus, has over 30 years of experience in the field of thermal engineering. Ms. Mosier was a 2017 recipient of NASA’s highest award, the Distinguished Service Medal, for her key contributions to mission success, thermal software development, and thermal training. Her diverse work portfolio includes a variety of instrument, balloncraft, and spacecraft systems, operating in cryogenic, convective and high-temperature environments and enabling more than twenty missions ranging from technology demonstrations to Earth and interplanetary science. Ms. Mosier is experienced in all aspects of thermal engineering, including design, analysis, requirements development, integration, testing, and flight operations. Ms. Mosier’s educational activities included developing and teaching thermal design classes for the Goddard Space Flight Center, University of Maryland, NASA Engineering & Safety Center, and Thermal and Fluids Analysis Workshops (TFAWS).
