Mass Production of Mature Lunar Regolith Simulant

As NASA prepares for future exploration activities on the Moon, there is a growing need to develop higher fidelity lunar soil simulants that can accurately reproduce the properties and behavior of lunar soil. Simulants are employed on earth to verify the performance of equipment, mechanisms, structures and processes to be used on the lunar surface. One of the significant limitations of current simulants is the lack of constituents, such as agglutinates and spherules, which often contain nano-phase iron (Fe0). These constituents are needed in any high fidelity simulant. Recently, Plasma Processes, Inc. (PPI) has developed a process to create simulated agglutinates and volcanic glasses from JSC-1A lunar regolith simulant. Microstructural characterization has shown that these components contain an appreciable amount of nano phase Fe0. However, current production of these simulant additives is limited. The ultimate objective of this Phase I effort is to develop an economical, large scale manufacturing process to produce simulant agglutinates and volcanic glasses. This production process promises to be a viable route for significantly enhancing the fidelity of existing and future lunar regolith simulants.

Feedstock for development and verification of in-space fabrication: Si - solar cells; Al, Ti, Fe - structural use; O2 (H2O) for life-support, habitat and propulsion use, high fidelity lunar simulant for dust, abrasion, mining & excavation research.

This is early/mid-stage (TRL 6) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

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.
