In-situ resource utilization may be an enabling technology that could allow humans to travel to and remain on Mars long-term. Mars Oxygen In-situ resource Utilization Experiment (MOXIE) is a technology development payload for the NASA Mars2020 rover that aims to demonstrate the production of oxygen from the Martian carbon dioxide atmosphere. In this paper we describe the thermal design of the Solid OXide Electrolysis (SOXE) subsystem, which operates at 800° C, including a discussions of the mechanical requirements for operating a SOXE stack, high-temperature materials chosen, and system constraints to maximize operability within the Mars2020 mission. We also describe testing and thermal model correlation used to validate the design and predict its performance on the surface of Mars.
