Delft, Netherlands – 21th December 2025 — Dawn Aerospace has reached important technical milestones under the European Commission–funded GEOryder programme, supporting the development of robust, next-generation propulsion systems designed for long-duration operations in the geostationary (GEO) environment.
Recent work within the programme has focused on Composite Overwrapped Pressure Vessel (COPV) qualification and radiation-tolerance testing, both critical steps in ensuring reliable performance under the demanding conditions of high-radiation orbits. These activities directly support the programme’s goal of maturing propulsion technologies suitable for GEO missions, where durability and resilience are paramount.
Alongside these efforts, Dawn Aerospace continues to progress development of its B200 system, with upcoming workstreams including Total Ionising Dose (TID) testing and the advancement of a ground demonstrator. Together, these activities form a coherent pathway toward flight-ready propulsion solutions for next-generation satellite missions.
Dawn Aerospace is proud to contribute its propulsion expertise to the GEOryder consortium and to collaborate with European partners in strengthening Europe’s in-orbit servicing and propulsion capabilities.
