IENAI Space

IENAI Space is a Spanish electric propulsion company founded in 2018 and headquartered in Madrid, developing miniaturized electrospray thrusters for CubeSats and small satellites. The company's Athena electrospray thruster system provides precise, high-efficiency propulsion for attitude control, orbit raising, and deorbit maneuvers on nanosatellites where conventional chemical propulsion is impractical due to size and safety constraints. IENAI Space is backed by ESA's Business Incubation Centre in Spain and is part of Spain's growing commercial space technology sector, contributing to Europe's capability in small satellite propulsion.
