CubeSat Ambipolar Thruster for LEO and Deep Space Missions

Completed Technology Project

Project Description

CubeSat Ambipolar Thruster for LEO and Deep Space Missions
Aether Industries proposes the development of a novel, primary plasma propulsion system that is well suited for small spacecraft. This technology, called the CubeSat Ambipolar Thruster (CAT), would provide CubeSats and other micro- and nano-satellites with the propulsive capability to make meaningful orbital plane and altitude changes — capability that does not currently exist with state-of-the-art micropropulsion technologies. As such, the CAT engine is an enabling technology that supports NASA, commercial, university, and military CubeSat needs from constellation deployment to lunar orbit insertion and beyond. In the CAT engine, a high-power RF plasma discharge is expanded adiabatically along a magnetic nozzle topology established by permanent magnets. A resultant ambipolar electric field accelerates the ions to high energies to generate thrust while retaining high propellant utilization. The CAT engine offers a means of providing efficient and high thrust-to-power primary propulsion for CubeSats and microsatellites. The CAT engine promises to change the CubeSat paradigm from passive sensor carriers to fully capable mission-completing spacecraft. Successful implementation by our team will result in the transition of technology developed into the commercial sector by a small business, the engagement of the next generation of the space sector workforce, and the infusion of an advanced in-space propulsion technology for future NASA, commercial, and government missions.
