Lunar Spectral Irradiance Monitor

During this effort an instrument for calibrating the lunar irradiance will be designed. Such an instrument will lead to reliable exoatmospheric calibration for past, current, and future earth-viewing instruments and improve the accuracy of their data products, which in turn will improve climate change and weather models. The instrument will measure both the solar and lunar irradiances, which will enable cross calibration with the TSIS mission. The proposed instrument concept has been formulated to take advantage of the near-collimated nature of the input signals. The work plan is to develop detailed ray-trace and radiometric models of the instrument. The error budget for the instrument will be analyzed and pre- and post-launch calibration plans will be formulated.

The system is targeted for deployment on a small-SAT (6u). It will provide accurate calibration of the lunar irradiance, which in turn will greatly reduce the need for on-board calibration for future NASA low earth orbit, earth-viewing instruments.

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.
