Solutions for SmallSats
Introducing the Nexus Osprey
Enpulsion’s Nexus Osprey propulsion system meets the unique mobility requirements of spacecraft ranging from 150-500kg.
Compact
Nexus Osprey delivers 500 - 4,500s specific impulse with a propellant four times denser than xenon—packing high performance into a compact, efficient design.
Reliable
With approximately 480 ion emission sites and parallel high-voltage supplies, Nexus Osprey’s design offers exceptional resilience and system-level robustness.
Versatile
With its modular architecture, Nexus Osprey scales easily — configurable in clusters of 1 to 4 units to deliver propulsion precisely tailored to mission-specific requirements.
Features
Enpulsion Powers SmallSat Missions With Safety & Precision
Mature Technology
Flight-Proven Foundation
Built on the in-orbit success of over 270 flight-proven propulsion systems, Nexus Osprey leverages years of insights gained through production experience across diverse mission profiles.
Streamlined Integration
Plug-and-Play Design
Thanks to its design without tanks or fluidic systems, Nexus Osprey installs via standard mounting panels and harnessing, connecting within a 15-inch ESPA-class ring.
Thrust-To-Power Ratio
Optimized Thrust Efficiency
Optimized for power and performance, Nexus Osprey increases thrust-to-power efficiency over lower-power systems by intelligently scaling beam output.
Debris Safety
Inherent Operational Safety
With no pressurized tanks or stored chemical energy, the system eliminates explosive risk during active operation or in-orbit collisions, enhancing overall spacecraft safety.
Indium Propellant
Stable, Safe Fuel Source
Indium is a nontoxic, unpressurized metal sourced as a by-product of zinc refining. More than 1,000 tons are produced annually, offering a stable, accessible, and safe propellant option.
Indium Powered Propulsion
Powered by Enpulsion’s innovative FEEP technology, the Nexus Osprey delivers precise, adjustable thrust by using a powerful electromagnetic field to ionize and accelerate liquified metal propellant.
Next-Level Maneuverability
Indium propellant liquifies in orbit to generate finely tunable thrust, delivering efficient, precise maneuverability throughout the entire life of the mission.
