Active TRL 4 (started at 4, targeting 6)
Because remote sensing from outside a space vehicle is expected to enable new science measurements, researchers are developing the Integrated Remote Imaging System – Ultraviolet (IRIS-UV) to operate in an external space environment. Mounted on a launch vehicle’s booster, IRIS-UV is designed to sense when the capsule has separated from the propulsion module, power itself on, and then gather spectral data of atmospheric brightness and transmission in UV. Temperature, vibration/acceleration, and contamination data will help researchers determine the suitability of the external access location.
Problem Statement
Currently, remote sensing in the environment outside of air/spacecraft is extremely difficult. Information provided by IRIS-UV would be instrumental to understanding the range of measurements practical from suborbital platforms, including requisite solar elongation for daytime observations from altitude. Measurements and analysis from this demonstration will be used to characterize the amount and distribution of solar illumination scattered by the atmosphere throughout flight.
Technology Maturation
In demonstrating remote sensing from an external payload on a commercial suborbital platform, the technology’s ending TRL is anticipated to be 7.
The Integrated Remote Imaging System - UltraViolet (IRIS-UV) operates in external environments at altitudes up to 100 km (i.e., in the absence of ozone). It serves to identify the range of practical measurements from suborbital platforms. This would benefit future NASA missions and the commercial space industry.

Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 4) — 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.
