Novel Materials for Mirror Substrate in Space Telescopes, Phase I

Completed

Description

Advanced Materials Technology, Inc (AMTI) responds to the NASA solicitation S2 "Advanced Telescope Systems" under subtopic S2.05, "Optics Manufacturing and Metrology for Telescope Optical Surfaces". The proposed program is aimed at developing large, ultra-lightweight mirror substrate, including membrane optics for very large aperture space telescopes. The novel materials offer considerable weight and cost savings. In order to prevent significant figure error, mirror substrate materials should have very low (ideally zero) coefficient of thermal expansion (CTE), low coefficient of moisture expansion (CME), low cure shrinkage, low internal stresses, low outgassing, and high thermal and environmental stability. The ultimate goal of the proposed Phase I program is to develop thin mirror substrate materials that will meet the desired requirements. Once the feasibility of the proposed technology is demonstrated in Phase I, we shall scale-up the thin mirror substrate technology in a Phase II program to meet the NASA requirements.

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.
