Space Debris Threat Mitigation via characterization of strain rate effects by Maximum Entropy Atomistics

Completed TRL 3 (started at 2, targeting 3)

Description

Space Debris and micrometeoroid threat mitigation poses a significant and growing future challenge to virtually all NASA missions. As such, there is a direct need to understand the mechanics and physics of any such impact events. However there is an inherent difficulty in understanding strain rate effects using small scale physics model due to the extremely short timescales involved when considering atomic motion. We propose a methodology, max-ent atomistics, which takes into account in an average sense the extremely short timescales and allows prediction of atomic motion over much longer timescales, namely those of interest in impact threat mitigation.

Benefits

This methodology allows prediction of atomic motion over much longer timescales, namely those of interest in impact threat mitigation. This could be useful for space debris and micrometeoroid threat mitigation.

How to get involved

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.
