Enpulsion has launched Nexus, the company’s most advanced propulsion system to date. Designed for spacecraft up to 500 kilograms, Nexus delivers significantly increased thrust and enhanced orbit-raising capabilities, addressing the growing demand for responsive, high-performance electric propulsion in smallsat missions.
Built on Enpulsion’s heritage Field Emission Electric Propulsion (FEEP) platform, Nexus is a direct evolution of the company’s TRL 9 Micro R3 system that leverages the flight heritage of more than 280 units on-orbit. With a thrust-to-power ratio optimized for early mission phases, Nexus mitigates one of the primary limitations traditionally associated with electric propulsion—initial orbit-raising speed. With this innovation, Enpulsion’s Nexus offers a groundbreaking alternative to Hall Effect Thrusters (HET) in the smallsat class.
Nexus is ideally suited for a range of mission profiles, including orbit-raising and deorbiting for SDA-class buses, constellation maneuvering and maintenance, responsive government and defense missions, and station keeping support for larger platforms. Nexus is also designed for flexible clustering and offers a compact, non-ITAR solution for international customers seeking high-thrust performance in a scalable architecture.
Nexus continues Enpulsion’s commitment to innovative spacecraft maneuverability throughout mission life, supporting sustainable satellite operations and celestial stewardship. Seamlessly integrating with Enpulsion’s Cortex Smart Mobility Interface (SMI), the system features no pressurized tanks or chemical energy storage and uses a solid indium propellant for safe handling.
Nexus development is already underway, with Preliminary Design Review (PDR) scheduled for Q3 2025, Critical Design Review (CDR) in Q1 2026, qualification completion in Q3 2026, and production deliveries starting in Q4 2026.
With Nexus, we’re building on everything we’ve learned from years of flight heritage and direct customer collaboration,” said Alexander Reissner, CEO & Founder of Enpulsion. “This system brings new performance to the table while staying true to what sets our propulsion apart: precision, simplicity, safety, and superior performance for the entire mission life.”
