Enpulsion’s Micro R³ propulsion system is designed to meet the unique mobility requirements of spacecraft of 10-200kg.
Each 1.6 L module delivers over 50,000 Ns at 4,000 s Isp. Easily mounted to the spacecraft exterior, the Micro R³ supports standalone use or clustering for higher thrust missions.
Backed by 15+ years of development and extensive emitter testing, Micro R³ builds on the flight-proven foundation of the legacy Nano platform.
The Micro R³ operates across a wide range of Isp — from 1,500 s to 4,500 s — delivering the industry’s highest specific impulse while tailoring it to mission needs.
Micro-Newton Control Capability
Electrode voltage enables smooth, low-noise thrust control with micro-Newton precision, making the Micro R³ ideal for missions requiring maximum maneuverability.
Non-Explosive Design
With no pressurized tanks or stored chemical energy, the system eliminates explosive risk during active operation or in-orbit collisions, enhancing overall spacecraft safety.
Reliable Power Platform
The Power Processing Unit is based on NANO heritage. It uses lot-controlled EEE parts and offers flexible integration as a stacked configuration or separate module.
Powered by Enpulsion’s innovative FEEP technology, the Micro R³ delivers precise, adjustable thrust by using a powerful electromagnetic field to ionize and accelerate liquified metal propellant.
Indium propellant liquifies in orbit to generate finely tunable thrust, delivering efficient, precise maneuverability throughout the entire life of the mission.
