Astroscale Achieves Historic Space Junk Rendezvous

Astroscale has successfully completed the world’s first rendezvous with a piece of space junk, marking a significant milestone in space debris management. The mission involved the company’s ADRAS-J satellite, which approached a defunct upper stage from a Japanese H-IIA rocket that has been in orbit since 2009.

Mission Overview

ADRAS-J launched in February 2024 and has been conducting operations in a polar orbit over 350 miles above Earth. On November 30, 2024, it achieved a close approach to the H-IIA rocket, coming within just 15 meters (49 feet) of the object. This mission is part of a public-private partnership with the Japan Aerospace Exploration Agency, which contributed $13 million to the project.

Technical Challenges

Rendezvousing with uncontrolled space debris presents unique challenges compared to cooperative objects like the International Space Station. The H-IIA rocket lacks navigation aids, making the mission more complex. Astroscale’s technology demonstrated the ability to navigate autonomously using cameras and laser sensors.

Future Plans

Astroscale plans to launch ADRAS-J2 in 2027 to further this initiative. This upcoming mission will include a robotic arm to attach to the H-IIA rocket and guide it back into the atmosphere for destruction. This capability positions Astroscale as a key player in the emerging commercial satellite servicing industry.

Funding and Partnerships

Astroscale has attracted significant investment, raising nearly $400 million in venture capital before its public listing in June 2023. The company has contracts with various government agencies, including a recent $25.5 million deal with the US Space Force to develop a satellite refueler.

Conclusion

The successful rendezvous with the H-IIA rocket demonstrates Astroscale’s capability in addressing space debris issues while opening avenues for satellite servicing and inspection. As the demand for space debris removal grows, Astroscale’s advancements in rendezvous and proximity operations technology will be critical.
