About the Company

Astroscale

On-orbit satellite servicing and debris removal

Astroscale provides on-orbit satellite servicing to extend mission lifetimes and reduce space debris. Its offerings include End-of-Life services (ELSA-d and ELSA-M) to capture and de-orbit defunct satellites, Active Debris Removal (ADRAS-J) to approach and inspect debris, Life Extension (LEXI) for in-orbit refueling planned for 2026, and in-situ space situational awareness (ISSA) to monitor the space environment. It enables docking plates attached pre-launch to allow future servicing or removal, serving governments (JAXA, UK Space Agency, ESA) and commercial operators (Eutelsat, OneWeb). Its goal is to create a sustainable space environment by enabling safe rendezvous, servicing, and debris removal in low Earth orbit and geostationary orbit and by shaping regulations for responsible space activity.
