Astroscale Japan Advances In-Space Refueling with REFLEX-J Mission
Astroscale Japan is developing a groundbreaking spacecraft, named REFLEX-J (Refueling for Extension and Flexibility – Japan), to demonstrate the feasibility of refueling satellites directly in orbit. This initiative, funded by a meaningful contract awarded in January through Japan’s Key and Advanced Technology R&D program, aims to dramatically extend the operational lives of existing satellites and reshape the future of space infrastructure.
The REFLEX-J mission will leverage Astroscale’s established expertise in Rendezvous,Proximity Operations,and Docking (RPOD) technologies. The spacecraft will incorporate advanced robotics, computer vision systems, and fuel transfer mechanisms to conduct a chemical propellant refueling demonstration in low earth orbit.A key component of the five-year, JPY 10.8 billion project involves extensive ground testing with various propellants to ensure the technology can be adapted for use with satellites in geostationary orbit and those utilizing electric propulsion. An in-orbit demonstration is planned for around 2029.
According to Eddie Kato, Managing Director of Astroscale Japan, REFLEX-J is central to the company’s vision of a ”circular economy in space,” prioritizing strategies of Reduce, Reuse, Repair, Refuel, and Remove. Refueling, in particular, offers a pathway to minimize the need for costly and environmentally impactful new satellite launches while maximizing the utility of existing assets.
By successfully demonstrating reliable on-orbit refueling, Astroscale Japan intends to establish a new benchmark for sustainable space operations and contribute to the long-term health of the orbital environment.
