Astroscale, a British subsidiary of Japan’s Astroscale, is preparing for a critical design review early next year for the End-of-Life Services by Astroscale-Multiple (ELSA-M) program. This innovative mission aims to remove a non-operational OneWeb broadband satellite from low Earth orbit (LEO) in 2026, marking a significant milestone in addressing the growing threat of space debris.

Development Progress
The ELSA-M program has successfully completed several vital milestones, including the completion of subsystem level developments and the procurement of flight hardware. Currently, a 500-kilogram servicer is in the “flatsat” phase, which involves rigorous testing and checkout processes. The onboard guidance, navigation, and control system is particularly complex due to the challenging Rendezvous and Proximity Operations necessary for capturing the non-operational OneWeb spacecraft. This level of sophistication signals a leap forward in technology aimed at sustainable space practices.
Flight Software and Capture Mechanism
Astroscale UK’s dedicated team is focused on finalizing the flight software for the ELSA-M initiative. The software will enable the servicer to employ a unique capture mechanism that is compatible with magnetic docking plates located on OneWeb’s satellites. This approach to capturing space debris marks a significant refinement in de-orbiting methodologies, pointing towards a future where the removal of defunct satellites may become a routine operational task.
Integration and Launch Plans
Astroscale is on a well-structured timeline, aiming to integrate ELSA-M subsystems in 2025 with a launch planned for the second quarter of 2026. There is a strong possibility that the mission will utilize a SpaceX Falcon 9 rocket to reach OneWeb’s operational orbit, ensuring an efficient ascent to the satellite’s current position in LEO. This logistical planning underscores the practical aspects of executing space missions in an arena that increasingly demands speed and efficiency.
Significance of Mission
The ELSA-M program stands out as a groundbreaking endeavor in commercial space activities, as no other company or nation has commercially captured and removed a spacecraft from orbit, making this mission a pioneering effort. Astroscale is not only focusing on this mission; it is also actively engaged in additional debris removal initiatives and efforts to enhance space situational awareness. Through these various efforts, the company contributes significantly to the global conversations surrounding space sustainability and safety.
Conclusion
The ELSA-M program is a crucial step in addressing the issues associated with space debris and promoting more sustainable practices in space activities. This mission not only has the potential to reshape how we think about the end-of-life management of satellites, but it could also influence policy and commercial strategies within the broader space industry. With increasing concerns regarding the sustainability of our space activities, initiatives like ELSA-M are essential for ensuring a safer future in Earth’s orbital domain.
