Aperture: A Precise Extremely large Reflective Telescope Using Re-configurable Elements

Completed TRL 2 (started at 1, targeting 2)

Description

Northwestern University, teamed with the University of Illinois (UIUC), proposes to develop a game changing technology for large deployable optical quality mirrors. The innovation combines the concept of a flying magnetic write head with a magnetic smart material that coats the back of the mirror. Northwestern Univ. will work on the materials and shaping the mirror with a magnetic field. UIUC will work on coupling the deployment design to a flying magnetic write head design. Deployable and deformable reflecting membrane mirror have been worked on in the past, but so far the ability to provide post deployment figure corrections to the level of \u03bb/20 has eluded the space community. The Phase I NIAC proposal will identify possible solutions to the main problems, such that a Phase II will take the program to TRL 3 or beyond. Some of the hurdles will be coating in such a way that the coatings (front and back) do not distort the mirror beyond our ability to correct. Another hurdle will be ensuring that the corrected mirror retains its shape for significantly long periods of time thereby minimizing the frequency of routine mirror maintenance.

Benefits

Engaging the public: Northwestern has ties to Adler Planetarium that will give the potential both for public lectures as well as displays that reach over 500,000 visitors and over 90,000 students and teachers each year. Also, both UIUC and Northwestern engage the public in open lecture to their surrounding communities. The outcome of Phase I will produce drawing and schematics perfect for presentations and displays at the respective campuses and at Adler.

How to get involved

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.
