Arkadia Space's Ariel Engine Achieves Technological Readiness for European Space Propulsion Market
The Ariel engine, developed by Arkadia Space, has reached TRL 6 status, allowing its entry into the international market. This 250 N monopropellant engine utilizes 98% hydrogen peroxide (HTP) as a greener alternative to hydrazine.
Its first application will be in the attitude control system of future launchers from MaiaSpace, following a contract signed in early 2025. The project, part of the ESA's Future Launchers Preparatory Program, addresses the need for safe, cost-effective propulsion systems.
The use of HTP can reduce atmospheric emissions by up to 40% compared to hydrazine. Arkadia Space built a new testing facility in Castellón, completing extensive tests and prototypes within 24 months. The collaboration with ESA has been crucial for achieving design validation. Following the ESA contract, Arkadia aims to conduct further testing and seeks partnerships for broader application of the Ariel engine in reusable space vehicles.
