NASA’s Carbothermal Reduction Demonstration (CaRD) project completed an important step toward using local resources to support human exploration on the Moon. The CaRD team performed integrated prototype testing that used concentrated solar energy to extract oxygen from simulated lunar soil, while confirming the production of carbon monoxide through a solar-driven chemical reaction.
If deployed on the Moon, this technology could enable the production of propellant using only lunar materials and sunlight, significantly reducing the cost and complexity of sustaining a long-term human presence on the lunar surface. The same downstream systems used to convert carbon monoxide into oxygen can also be adapted to convert carbon dioxide into oxygen and methane on Mars.
The integrated prototype brought together a carbothermal oxygen production reactor developed by Sierra Space, a solar concentrator designed by NASA’s Glenn Research Center in Cleveland, precision mirrors produced by Composite Mirror Applications, and avionics, software, and gas analysis systems from NASA’s Kennedy Space Center in Florida. NASA’s Johnson Space Center in Houston led project management, systems engineering, testing, and development of key hardware and ground support systems.
