Mars Aqueous Processing System, Phase II
Completed
Description
The Mars Aqueous Processing System (MAPS) is a novel technology for recovering oxygen, iron, and other constituents from lunar and Mars soils. The closed-loop process selectively extracts and then recovers constituents from soils using acids and bases. The emphasis on Mars is production of useful materials such as iron, silica, alumina, magnesia, and concrete with recovery of oxygen as a byproduct. On the Moon, similar chemistry is applied with emphasis on oxygen production. Most lunar LOx processes only reduce FeO, which is generally present at just 10 to 15 percent in soils. All of the soil must be heated to reduce the contained FeO, resulting in substantial heat transfer issues. Thermal power requirements per unit of oxygen recovered are reduced by an order of magnitude and hydrogen losses are minimized if only a small mass of high-grade iron oxide concentrate, such as that produced by MAPS, is subjected to hydrogen reduction. MAPS is significant because it can be co-developed for Mars and Moon applications. The process would be commissioned first for oxygen production on the Moon. Modular enhancements for manufacture of additional products would be implemented on the Moon and then on Mars, thereby reducing risks and costs.

How to get involved
This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
