Canceled TRL 5 (started at 2, targeting 5)
Laser In situ Resource Analyzer (LIRA) is a sensor to detect trace water in oxygen propellant streams generated by in situ resource utilization (ISRU) systems operating in a lunar environment.
The LIRA sensor will enable verification of low (part-per-million) water content in propellant-grade oxygen streams in order to support sustainable lunar operations. LIRA is derived from laser spectrometer technology that has enabled gas composition measurements on the surface of Mars as part of the Mars Science Laboratory rover. Laser spectrometers have been shown to operate in diverse temperature and pressure conditions over a period of years.
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 5) — 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.
