Nickel-Syntactic Hybrid Mirrors, Phase I

Completed

Description

Astronomers strive to see farther and farther into the cosmos. These increased observation distances will gain access to a wealth of information that will enable a better understanding of the universe, and the origins of Earth. To gain these distances larger aperture telescopes are required. Current materials and fabrication processes for space-based mirrors have serious drawbacks that severely limit the size and therefore the performance of optical systems for imagery. These drawbacks fall primarily into the areas of mass properties, structural properties, thermal properties, and fabrication costs. Cornerstone Research Group, Inc. (CRG), proposes to develop a composite material system that will address the drawbacks of conventional materials and fabrication processes for space-based mirrors. This novel composite system will integrate syntactic materials (see background Section 2.4) with electroformed nickel foils to achieve a balance of mass, structural, thermal, and optical properties that dramatically advances the state-of-the-art for space-based mirrors. The composite material will also enable fabrication techniques that are faster and cheaper than current practices.

How to get involved

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.
