The concept of a circular economy within the Geostationary Earth Orbit (GEO) environment is increasingly gaining traction, driven by the innovative new modular concepts coming out of the new space GEO platform manufacturers. This approach emphasizes sustainability and efficiency, maximizing the utility of resources already present in space and minimising waste, but practical applications are required to ensure its success past the institutional head start. D-Orbit is addressing this directly with its new platform, GEA, developed with ESA as part of the ADRIOS RISE mission launching in 2027/28.
Life extension of operational telecom spacecraft is the obvious first target and is already part of the in-orbit servicing market offering, but it only represents one piece of the puzzle. Platforms need to be compatible with sharing in-orbit fuel reserves, enhancing the longevity and functionality of existing satellites and saving on launch effort. Furthermore, the installation of new modules on already deployed platforms will facilitate capability extensions, restorations, and platform refurbishments. Another significant practical application is the extraction and reuse of functional modules from failing or expiring satellites, promoting resource conservation and cost reduction. The ability to swap payloads allows for the modernization and refurbishment of in-orbit spacecraft, ensuring they remain state-of-the-art without the need for complete replacements. And finally, the stacking of in-orbit capabilities can lead to the creation of high-power space hubs, enabling novel space missions.
Looking ahead, the potential applications of a circular economy in GEO are vast. These include space-based manufacturing facilities using in-situ resources to reduce reliance on Earth-supplied materials, and the creation of modular, reusable space habitats for sustainable human presence. This framework can also advance space logistics and infrastructure, supporting long-term missions and deep space exploration. Ultimately, adopting a circular economy in GEO with the versatile modular architectures promises to revolutionize the space industry by promoting sustainability, reducing costs, and enhancing efficiency.
