Space industry in Luxembourg

The Luxembourg Space Agency (LSA) was founded on September 12, 2018, to implement the national space strategy. Unlike many similar organizations abroad, LSA does not directly conduct research or launch missions but fosters collaboration between key players in the space industry to accelerate innovation-driven businesses. The agency is modeled after a private firm with the primary goal to diversify Luxembourg's economy through space activities. LSA was a founding member of the Artemis Accords and focuses on In-Situ Resource Utilization (ISRU).

SES is one of the world's leading satellite operators, pioneering data connectivity solutions across geostationary (GEO) and medium-Earth orbit (MEO) constellations to deliver managed services worldwide. Headquartered in Luxembourg with a global presence spanning 50+ locations, SES serves telecommunications providers, broadcasters, enterprises, and governments with reliable, high-throughput satellite communications. The company operates a fleet of over 70 satellites in geostationary orbit providing comprehensive coverage across every continent. These GEO assets deliver video distribution reaching hundreds of millions of homes, enterprise networking, government communications, and mobility services for aviation and maritime customers. SES's Astra satellites form the backbone of European direct-to-home television distribution. SES's revolutionary O3b mPOWER constellation represents the most advanced MEO communications system ever deployed. Operating at approximately 8,000 kilometers altitude - significantly closer than traditional GEO satellites - O3b mPOWER delivers fiber-equivalent, low-latency broadband connectivity with terabits of throughput capacity. The system's fully steerable, electronically-formed beams enable dynamic capacity allocation across thousands of coverage cells, providing flexibility to serve evolving customer demands. The combined GEO-MEO multi-orbit architecture uniquely positions SES to deliver differentiated solutions spanning video broadcast, cloud connectivity, government missions, and mobility applications. SES Networks provides managed data services leveraging the satellite infrastructure, while SES Video delivers broadcast and streaming solutions. The company continues investing in next-generation capabilities including software-defined satellites and ground infrastructure modernization. Through acquisitions of Intelsat and strategic partnerships, SES is creating the most comprehensive satellite communications platform to meet growing global connectivity demands.
