December 7, 2022 – Astroscale Japan Inc. and the Japan Aerospace Exploration Agency (JAXA) have started concept co-creation activities for a satellite refueling service, under the JAXA Space Innovation through Partnership and Co-creation (J-SPARC). The aim is to explore concepts for a fuel delivery service for one year, toward the realization of space sustainability. The mission concept will be for providing refueling service on orbit to satellites that are both prepared and unprepared to be refueled. Astroscale Japan will study the feasibility of satellite refueling services and consider international collaboration with other Astroscale subsidiaries and partners, applying the rendezvous and proximity operations technology demonstrated in the End-of-Life Services by Astroscale – demonstration (ELSA-d) mission, and robot arm and hand technology currently under development to the refueling work. JAXA will study the technical feasibility of an on-orbit refueling system, examine ground test equipment for fuel transfer evaluation, and provide technical knowledge and advice based on the studies.
