Kepler, Astrolight to Test ESA’s ‘Fiber in the Sky’

payloadspace.com·Apr 15, 2026

The European Space Agency (ESA) has selected a team led by Kepler Communications to test its HydRON orbital communications network, with a satellite launch planned for 2027 that will carry Astrolight's ATLAS-X laser communications terminal. This initiative aims to enhance secure data transmission capabilities in space and address the growing demand for optical communication solutions amidst increasing radio frequency congestion.

The European Space Agency's collaboration with Kepler Communications and Astrolight to test the "fiber in the sky" HydRON orbital communications network is a significant development in space-based internet infrastructure. This initiative, which involves launching a satellite in 2027 equipped with Astrolight’s ATLAS-X laser communications terminal, could potentially address critical security concerns by providing a secure alternative to radio communications, reducing vulnerabilities to interception by foreign entities. This project is part of a larger €1B investment in optical and quantum communications, signaling a strong investment opportunity in these advanced communication technologies within the space sector.
