Fluidic Telescope Experiment (FLUTE)

The Fluidic Telescope Experiment (FLUTE) aims to validate a method for developing fluidic optical components in microgravity conditions for use in space telescopes and optical components. The approach leverages the natural surface tension of liquids to achieve nanometer smooth optical surfaces that form liquid and solidified optical components of various geometries. Researchers expect to develop reflective components by using reflective liquids or via atomic layer deposition (ALD) onto a solidified component. Parabolic flight testing will permit researchers to test different liquids, geometries, and deployment mechanisms and to optimize conditions for future development of the method.

Fluidic shaping and in-situ measurement of liquid lenses in microgravity (Sep 2023)

Flight tests for the Fluidic Telescope Experiment (FLUTE) aim to validate a method for developing fluidic optical components in microgravity conditions for use in space telescopes. The approach leverages the natural surface tension of liquids to achieve nanometer smooth optical surfaces that form liquid and solidified optical components of various geometries. This approach, which is possible only in microgravity, could advance space-based astronomy by deploying large fluidic components in place of lenses and mirrors, significantly reducing cost, construction time, and failure risk. This has the potential to benefit NASA missions, the commercial space industry, other government agencies, and the nation.

This is early/mid-stage (TRL 6) — 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.
