Adjustment of the orbit of a spacecraft using the forces created by an electro-dynamic space-tether has been shown as a theoretic possibility in recent literature. Practical implementation is being pursued for larger scale missions where a hot filament device controls electron emission and the current flowing in the electrodynamic space tether. Applications to small spacecraft, or space debris in the 1-10 kg range, possess difficulties with electron emission technology, as low power emitting devices are needed. This paper addres- ses the system concepts of a small spacecraft electrody- namic tether system with focus on electron emitter design and manufacture using micro-electro-mecha- nical-system (MEMS) technology. The paper addresses the system concepts of a small size electrodynamic tether mission and shows a novel electron emitter for the 1-2 mA range where altitude can be effectively affected and other orbit parameters can be controlled for small sized missions, without on-board propulsion.
