The Nereus product family is a modular and scalable system built around monopropellant and bipropellant engines. It aims to usher in a new paradigm for In-Space mobility for space vehicles and satellites.
On Earth, what matters most are non-toxic propellants that allow safe handling, but in space, efficiency is everything and every second counts to get the payload operational as quickly as possible. With Nereus, there's no need to compromise, the objectives set for space don't impact operations on Earth.
You can acquire a thruster independently or integrate the complete system, according to what your mission needs.
Engines that drive mission success
From small satellites to large vehicles
At Pangea, we specialize in chemical propulsion for spacecraft, but that is our focus, not our limit. We're pushing boundaries and exploring every technological possibility.

Additional technical views coming soon
An aerospike engine maintains optimal performance regardless of pressure or altitude changes. Until now, they were largely conceptual, but at Pangea we made history by building and testing the world's first Methalox aerospike engine.
The ARCOS platform transforms this performance and sustainability breakthrough into a real-world solution. Its modular design adapts thrust levels, geometry, and interface configurations to meet diverse mission requirements, making ARCOS compatible with a wide variety of launcher sizes.
