A regolith oxygen extraction system that extracts oxygen and produces molten regolith by processing and heating a continuous regolith feed. The system feeds regolith through a vertical hopper to a reaction chamber, the regolith itself sealing the inlet to the reaction chamber while maintaining continuous flow. The heated regolith reacts within the reaction chamber to produce oxygen and processed regolith. The processed regolith is removed from the reactor chamber through an extrusion nozzle, the processed regolith itself sealing the produced gases within the reactor chamber while maintaining continuous flow of processed regolith. The system employs non-contact reaction temperature measurement and rapid oxygen content measurement in the regolith upstream and downstream of the reaction zone, and may be integrated with multiple oxygen extraction methods.
