This page includes a growing list of ongoing, completed, and prior R&D efforts for various open-source, ultra-low cost propulsion systems for nanosatellites, such as Cubesats and PocketQubes, for educational, research, enthusiast, and industry. These efforts mark a unique approach towards electric propulsion development that radically diverges from conventional industry and academic initiatives, and aims to advance and change the playing field and accessibility of electric propulsion.
