IENAI Space

IENAI Space is a Spanish technology firm specialising in the design and manufacture of high-efficiency electric propulsion systems for small satellites. The company occupies a specific position in the upstream aerospace value chain as a Tier 2 subsystem supplier, focusing on the miniaturisation of thrusters to enable precise orbital manoeuvres and station-keeping for CubeSats and SmallSats. Their primary innovation revolves around electrospray technology using ionic liquids. The organisation has formalised development pathways through the European Space Agency (ESA) and has participated in programmes supported by the Spanish Centre for the Development of Industrial Technology (CDTI). Their flagship hardware, the ATHENA thruster system, is designed for scalability to meet varying mission profiles from Low Earth Orbit to deep space exploration. The company collaborates with satellite integrators and launch service providers across Europe to integrate these modular propulsion units into diverse bus architectures. Prospective buyers should verify the specific Technology Readiness Level (TRL) of the propulsion modules relative to their intended mission duration and total impulse requirements. It is advisable to review the flight heritage of the ATHENA system and confirm the lead times for custom propellant configurations. Furthermore, partners should assess the company's compliance with international space debris mitigation guidelines regarding end-of-life disposal capabilities.
