Completed TRL 8 (started at 3, targeting 8)
The first interplanetary CubeSats, NASA’s MarCO A and B, used a set of cold gas thrusters for attitude control and course corrections during their cruise to Mars, alongside the Mars InSight lander. Accion partnered with NASA and NanoAvionics Corporation to orbitally test a propulsion system targeting the same capabilities as those required for the MarCO mission, but with a smaller and lighter system that uses less power. Lessons from the orbital testing are being incorporated into future versions of the Accion TILE propulsion system.
This project will demonstration a high efficiency propulsion system, capable of operating at lower power, with improved thermal characteristics, in a smaller simplified package compared to equivalent systems which could enable a greater number of low-cost science and exploration missions in the future
Listed on TechPort itself — the most direct way to ask about this specific project.
This is a mature technology (TRL 8) — 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.
