European projects advance orbital servicing for extended space missions

European initiatives are pushing forward the capabilities of on-orbit servicing to extend spacecraft lifespans and enable more sustainable space operations. These efforts are critical for evolving space infrastructures and meeting the demand for enhanced satellite functionality.

The EROSS IOD project, with an EC maximum contribution of €25,983,822 and a total cost of €25,983,823.75, is developing European Robotic Orbital Support Services for in-orbit demonstration. Active from January 2023 to December 2025, its objectives include autonomous rendezvous, refuelling, Orbital Replaceable Unit (ORU) exchange, repair, and waste management. The project aims to establish technologies for future smart, flexible, and modular space infrastructures.

Similarly, the ASTROLIFT project, running from February 2024 to January 2026, focuses on Autonomous Spacecraft Technology for Repair Operations, Lifespan Improvement and Flight Testing. This project, which received an EC maximum contribution of €2,499,999 and had a total cost of €4,203,837.5, involves D-Orbit presenting GEA, a spacecraft designed for in-orbit servicing of commercial satellites in geostationary orbit. GEA will feature a robotic arm with 7 degrees-of-freedom and precise accuracy, alongside electric propulsion and navigation systems tailored for capturing and maneuvering customer satellites.

Both projects underscore a paradigm shift towards designing spacecraft with on-orbit servicing in mind, moving away from disposable systems. The growing demand for satellite life extension from commercial customers highlights the emerging market for these technologies.

What this means: These projects are laying the groundwork for a future where satellites can be maintained, refuelled, and upgraded in space, significantly extending their operational lives and reducing space debris. Such advancements are vital for the long-term sustainability and economic viability of space activities.
