Completed TRL 4 (started at 3, targeting 4)
One of the most effective methods of steering a Sail is to move the spacecraft off the Sail’s center, changing the center of Mass. Any shift in the Center of Mass (CM) of the craft relative to the center of pressure (CP) on a sail effectively changes the Sail’s attitude. We propose to demonstrate TRL 4 with a mock Solar Sail and Spacecraft Bus operating on an air-table (modified air-hockey).
The use of electromagnets to couple a spacecraft bus to spinning or static solar sail is revolutionary – it will reduce the coupling and control mass by a factor of 10 or more and enable far larger sail area by allowing the sail to rotate.
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 4) — 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.
