Tokyo, Japan, Dec.7, 2022 – Astroscale Japan Inc. (“Astroscale Japan”), a subsidiary of Astroscale Holdings Inc. (“Astroscale”), the market leader in satellite servicing and long-term orbital sustainability across all orbits, and the Japan Aerospace Exploration Agency (JAXA) have started concept co-creation activities for a satellite refueling service^※1, 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.

"On-orbit services are the sustainable infrastructure of the space economy,” said Miki Ito, Managing Director of Astroscale Japan. “Over the past few years, awareness of the orbital environment and space sustainability has increased rapidly, and the demand for such services has grown significantly. We are pleased to be working with JAXA on refueling as a function of life extension, and by 2030, we plan to be able to make on-orbit services, including life extension, a routine basic infrastructure service."

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.

Earth’s orbits, particularly low-Earth orbit, are becoming crowded due to an increase in space activity, which has led to the accrual of orbital debris. If this trend continues without a solution, it will become difficult to safely use those orbits. To solve this problem and achieve a sustainable space environment, it is an important to realize a circular economy through on-orbit services, which include removing and reducing space debris, and reusing, repairing and refueling spacecraft.

Refueling has cost-reducing effects for satellite operators and increases revenue potentially^※2. By extending the life of satellites, it will help reduce the number of satellites and launches required to carry out current space activities. It also enables additional missions by removing fuel constraints.

“On-orbit satellite refueling is a new service that overcomes the longevity factor of fuel depletion and enables satellite operations to continue for a longer period of time,” said Hiroyuki Sugita, Director of Research Unit II at JAXA’s Research and Development Directorate. “We expect that providing JAXA's knowledge of refueling technology will advance the private sector’s space projects and contribute to the realization of sustainable space activities.”

※1 meaning to resupply satellites with propellants such as hydrazine, oxidizers, xenon, pressurized gas. Propellants that do not involve chemical reactions are included, but for the sake of clarity as a general term, propellants are described as fuel.

※2 According to Northern Sky Research, a U.S. space market research firm, it is estimated that by 2031, life extension services such as refueling will generate $4.7 billion in revenue.

About JAXA Space Innovation through Partnership and Co-creation (J-SPARC)

J-SPARC is a co-creation R&D program that begins with dialogue between JAXA and private companies and others looking to move into the space business and, with the commitment of both parties to commercialization, then moves on to considering business concepts and developing/demonstrating exit-oriented technologies to create new businesses. Launched in May 2018, the program has so far resulted in the commercialization (commoditization and go-live) of VR, food, education, entertainment, and telecommunications endeavors by private-sector companies through the pursuit of about 40 projects and activities. The co-creation of business concepts entails such activities as market research and business concept studies, while joint business demonstration involves joint feasibility studies prior to commercialization as well as joint technology development and demonstration.

About Astroscale

Astroscale is the first private company with a vision to secure the safe and sustainable development of space for the benefit of future generations, and the only company dedicated to on-orbit servicing across all orbits.

Founded in 2013, Astroscale is developing innovative and scalable solutions across the spectrum of on-orbit servicing, including life extension, in-space situational awareness, end-of-life, and active debris removal, to create sustainable space systems and mitigate the growing and hazardous buildup of debris in space. Astroscale is also defining business cases and working with government and commercial stakeholders to develop norms, regulations, and incentives for the responsible use of space.

Headquartered in Japan, Astroscale has an international presence with subsidiaries in the United Kingdom, the United States, Israel, and Singapore. Astroscale is a rapidly expanding venture company, working to advance safe and sustainable growth in space and solve a growing environmental concern.
