The Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE)[1] is a technology demonstration on the NASA Mars 2020 Perseverance rover to investigate the production of oxygen on Mars.[2] On 20 April 2021, MOXIE produced oxygen from Martian atmospheric carbon dioxide using solid oxide electrolysis, the first experimental extraction of a natural resource from another planet for human use.[3][4] The technology demonstrated by MOXIE may eventually be scaled up for use in a human mission to provide breathable oxygen, oxidiser, propellant, and water by combining the produced oxygen with hydrogen.[5]
