PSI Ejecta Kinetic Energy Estimating Radar (PEKEER)

This project will quantify Plume-Surface Interaction (PSI) effects by developing a PSI ejecta kinetic energy estimation radar (PEKEER). PSI induced ejecta particles pose significant risk to landing vehicles; surface assets; and orbital assets. To date; there have been no direct measurements of PSI induced ejecta particle sizes; velocities; or kinetic energy on the lunar or Martian surfaces. PEKEER measurements will quantify PSI effects and will directly inform PSI modelling efforts for Entry; Descent; and Landing (EDL).

This project will investigate the feasibility and critical function of a multi-frequency; PSI ejecta kinetic energy estimating radar (PEKEER) by completing proof-of-concept testing in a laboratory environment. The kinetic energy of PSI induced ejecta particles needs to be quantified to determine how to adequately mitigate these ejecta particles. Ejecta speeds and sizes must be measured to estimate the amount of energy these particles carry and to assess which mitigations will be successful and which ones will fail.

This is early/mid-stage (TRL 2) — 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.
