A solar concentrator is tested as part of the Carbothermal Reduction Demonstration (CaRD) project, which aims to produce oxygen from simulated lunar regolith for use at the Moon’s south pole. During this integrated test, the team combined the concentrator, mirrors, and control software and confirmed the production of carbon monoxide.
NASA has successfully finished a critical test for a new machine called the Carbothermal Reduction Demonstration, or CaRD. This project is a big deal for sending humans to the Moon. The main idea is to use materials found on the Moon instead of bringing everything from Earth. This method is called In-Situ Resource Utilization, or ISRU. Using local materials changes the cost of space travel. It makes long trips much cheaper and easier.
The CaRD team tested a prototype that used concentrated sunlight. They aimed to pull oxygen out of soil taken from the Moon, which scientists call regolith. The tests were very hard and rigorous. The system worked well, successfully extracting oxygen. It also made carbon monoxide at the same time. This happened through a chemical reaction powered by the sun.
If this technology works on the actual Moon, it could change everything. It would allow astronauts to make rocket fuel using only Moon dust and sunlight. This would cut down the huge costs and problems of keeping people on the Moon for a long time. Currently, we must send food, water, and fuel from Earth. If we can make these things on the Moon, astronauts can stay longer. They do not need to wait for expensive supply ships from Earth.
The systems designed for this also work on Mars. On the Red Planet, the air is full of carbon dioxide. The same technology could turn that gas into oxygen and methane. Methane is another kind of fuel for rockets. This creates a closed system. It means astronauts could make their own air and fuel. This is a huge step for exploring deep space.
