Prediction of Regolith Ejection During Extraterrestrial Landings

The overall objective of the proposed work is to provide a better understanding of the transport of ejected lunar regolith during spacecraft landing on extraterrestrial bodies (Moon, Mars, asteroids, etc.) and to incorporate this knowledge into a first-principles model for wide particle size distributions. In order to develop this model, computer simulations using both the discrete element method and continuum theory, along with experimental data, will be used. This model will then be transferred to NASA engineers for use as a practical predictive tool in a variety of scenarios to assist in the design of systems to mitigate the effects of regolith ejection. Such a predictive tool is crucial for the safety and future of space exploration.

This is early/mid-stage (TRL 3) — 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.
