About
ELSA-M is Astroscale’s first fully commercial End-of-Life (EOL) servicer, designed to demonstrate routine satellite removal services for the growing LEO constellation market. Building on magnetic capture technology validated by ELSA-d, ELSA-M enables removal of multiple prepared client satellites in a single mission — dramatically reducing cost per removal.
The servicer has a mass of approximately 520 kg and employs RPO to magnetically dock to client satellites equipped with Astroscale’s Docking Plate interface. Primary commercial customer is Eutelsat, targeting a OneWeb LEO satellite. The program has received support from the European Space Agency (ESA) and UK Space Agency (UKSA).
The development program passed Phase 1 Kick-Off in June 2024, Phase 3 and 4 Kick-Off in June 2025, and completed its Critical Design Review (CDR) on March 16, 2026 — the same day Isar Aerospace was selected as launch provider for the In-Orbit Demonstration mission.
