TFINER -- Thin Film Isotope Nuclear Engine Rocket

Active

Description

The Thin-Film Nuclear Engine Rocket (TFINER) is a novel space propulsion technology that enables aggressive space exploration  for missions that are impossible with existing approaches.  The concept uses thin layers of energetic radioisotopes to directly generate  thrust. The emission direction of its natural decay products is biased by a substrate to accelerate the spacecraft.  A single stage design  is very simple and can generate velocity changes of ~100 km/s using a few kilograms of fuel and potentially more than 150 km/s for  more advanced architectures.     

Benefits

The propulsion system enables a rendezvous with intriguing interstellar objects such as 'Oumuamua that are on hyperbolic orbits  through our solar system.  A particular advantage is the ability to maneuver in deep space to find objects with uncertainty in their  location. The same capabilities also enable a fast trip to the solar gravitational focus to image multiple potentially habitable exoplanets.   Both types of missions require propulsion outside the solar system that is an order of magnitude beyond the performance of existing  technology.

How to get involved

This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.

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.
