MUNICH – On Wednesday, March 4, Mynaric (Nasdaq: MYNA) announced it has been selected by the European Space Agency (ESA) for demonstration activities under Element 3 of the HydRON (High Throughput Optical Network) program.
The project will leverage Mynaric’s laser communications terminals for the in-orbit testing and validation of the “User Segment” within ESA’s burgeoning space-based optical data relay infrastructure.
Building Europe’s Terabit-Scale Optical Backbone
The HydRON Demonstration System is a cornerstone of ESA’s Optical and Quantum Communications – ScyLight program. It aims to establish a seamless, high-capacity optical network integrating space assets into terrestrial fiber grids.
Within Element 3, Mynaric will provide the technological framework for user-segment demonstrations, focusing on:
- In-Orbit Interoperability: Validating cross-regime links between Low Earth Orbit (LEO) and Medium Earth Orbit (MEO) platforms.
- Network Integration: Testing secure, terabit-per-second data relay capabilities under realistic operational conditions.
- Multi-Mission Support: Preparing for future hosted payload opportunities and emerging service use cases.
Strategic Continuity and Financial Recovery
This award follows Mynaric’s previous success in HydRON Element 2, where the company was tasked with developing a LEO satellite collector to bridge different orbital layers. The continued selection of Mynaric comes as the company maneuvers through a significant corporate transition. Following a successful exit from German StaRUG restructuring proceedings in late 2025, Mynaric is currently the subject of an intensified bidding war between defense giant Rheinmetall and Rocket Lab.
The project underscores Mynaric’s shift from a project-based firm to an industrialized “product-led” manufacturer, having already delivered over 100 CONDOR Mk3 terminals for the U.S. Space Development Agency’s (SDA) Proliferated Warfighter Space Architecture.
Executive Perspectives
“Through these demonstrations, we can further mature our technology, address interoperability requirements, and continue expanding our product portfolio to meet the evolving needs of multi-orbit and multi-mission space networks,” said Joachim Horwath, Chief Technology Officer at Mynaric.
“In the current geopolitical climate, resilient communications are more important than ever,” added Laurent Jaffart, ESA’s Director of Resilience, Navigation and Connectivity. “With Mynaric, we’re taking the next step in delivering an infrastructure that promotes interoperability, reliability and security.”
Timeline for European Space Infrastructure
The demonstration activities under Element 3 are expected to coincide with the main testing campaign of QuNET, scheduled for October 2026, which will further validate Mynaric’s Quantum Key Distribution (QKD) capabilities. The HydRON Demonstration System serves as the technical precursor to a fully operational European optical data relay network intended to support both institutional defense requirements and commercial high-speed backhaul.
