Iodine Radio Frequency (RF) Ion Thruster Development Testing

Busek proposes to develop a unique miniature Radio-Frequency Ion Propulsion System where Iodine replaces the typical xenon propellant. Integration of the high density, low pressure stored Iodine greatly enhances the performance of a CubeSat propulsion system, while eliminating the hazards, and accompanying pressurized tank safety issues and stringent procedures for same. In this program we will leverage our vast experience with miniature RF ion engines and our more recent Iodine electric propulsion research.

The iodine ion thruster technology provides the ability to precisely control the low thrust with atypical high specific impulse (Isp) and enables several mission applications including escape trajectory missions, orientation control and pointing controls, orbital maintenance and de-orbit applications.

This is early/mid-stage (TRL 3) — 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.
