NASA Glenn Research Center is backing a subcontract for a system-level in-situ resource utilization demonstration that will produce oxygen from lunar regolith, with the contractor expected to deliver a functional oxygen production demo plus performance data; the listed objective is to advance the technology to Technology Readiness Level 5–6, and the CLEATUS posting is dated 2026-09-08 with a recent update on 2026-09-27.
Technically, this is a direct step toward operational lunar life support and propellant production because oxygen is the dominant mass input for crew breathing and oxidizer supply; the broader NASA portfolio also shows multiple converging approaches, including carbothermal reduction, solar-concentrator systems, and molten regolith electrolysis, with NASA SBIR targets of 1,000 kg of oxygen per year for a pilot plant and 10,000 kg per year for full scale.
For the Ark, the priority is to track which extraction pathway reaches the highest maturity with the lowest imported mass, power, and consumable demand; integrate the operating assumptions, reactor hardware, gas handling, and regolith feed systems into preservation plans, and benchmark any candidate design against throughput targets of at least 1 metric ton per year pilot scale and 10 metric tons per year full scale, because oxygen production is a hard dependency for any long-duration lunar settlement.
