Advancing the TRL of a Compact, High Dynamic Range Ultraviolet Imaging Spectrometer

The UV spectral range has been specifically identified in the Decadal Survey as it is rich with key information that can be employed to study planetary systems. Ultraviolet spectroscopy has previously enabled studies of emission from atmospheres & exospheres, surface activity, and plasma properties related to bodies ranging from planetesimals to satellites to the major planets. The UV spectral range also provides diagnostics of surface characteristics including mineralogy, frost & condensation, and bulk ices. Because of these reasons, UV spectrometers have been included on most planetary missions dating back to the 1960s. We propose to advance the technology readiness level (TRL) of a compact, modular ultraviolet and visible imaging spectrometer that employs advanced detector, optical coatings, and grating. The instrument will enable the elimination of high voltage power requirements as well as a reduction in mass and volume; it will also exhibit reduced sensitivity to radiation and it will have higher dynamic range and greater overall stability. As part of the proposed effort, we will mature the spectrometer by advancing the delta-doped detector camera subsystem. We will evaluate the performance of the camera in CU-Boulder's testbed. University of Arizona will provide science objectives to help guide development, and will evaluate individual components as well as the full instrument in their testbed.

Developing instrument technology to improve measurements for future planetary science missions.

This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.

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.
