A Phase 2 Small Business Technology Transfer (STTR) proposal from Invocon, Inc. of Conroe, TX for a Spacecraft Leak Detection System was recently selected by NASA for contract negotiation. This technology development intends to provide a viable system to sense and locate air leaks from pressurized space station or lunar habitat modules caused by micrometeoroid and space debris impact events. The ability to detect, quickly locate, and mitigate a pressure vessel breach is critical to the safety of any long duration spacecraft.
