Precision Ion Nano Thruster

We are proposing the development of a new miniaturized and low power stand-alone “nano-thruster” instrument, the Precision Ion Nano-Thruster (PINT) to perform very fine thrusting in support of precision attitude and pointing control on space platforms. The miniature precision device development effort will be based on previous R&D results and experience, and proven technologies developed in collaborations between Espace Inc. and the MIT Space Propulsion Laboratory. The effort will focus on the miniaturization of the electronics and the high precision control of micro-fabricated ion-electrospray thrusters, leveraging the state of the art in the technologies, and optimizing the micro-thrusters for fine control and stability. The ultimate objective of the PINT development will be rugged, industrially and economically manufactured, miniature stand-alone electric thrusters, providing precision controlled ion beams.

The applications of the PINT thrusters are in the area of very high precision control of space platforms, in attitude or trajectories. Advanced technologies such as laser telecommunications or fractionated interferometric instruments require stable and precise controls for which PINT will provide an economical and practical tool for fine adjustments and stabilization. PINT will have applications in NASA future astrophysics observatories and fractionated space system designs.

The applications of the PINT thrusters are in the area of very high precision control of space platforms, in attitude or trajectories. Advanced technologies such as laser telecommunications require stable and precise controls. A commercial or governmental application is in fine stabilization and controls for small platforms using laser telecommunications.

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.
