japanese Startup Makes History with Closest-Ever Approach to Space Junk
Table of Contents
Astroscale, a Japanese company specializing in orbital debris removal, has achieved a groundbreaking milestone by coming within 15 meters of a defunct rocket stage in space. This unprecedented close approach, conducted by Astroscale’s ADRAS-J spacecraft, marks a meaningful step forward in the development of technologies to tackle the growing problem of space debris.
While the ADRAS-J mission was initially selected by the Japan Aerospace Exploration Agency (JAXA) for a demonstration project focused on approaching and observing JAXA’s H-IIA rocket upper stage, Astroscale went above and beyond the mission requirements.
“The objective was to demonstrate highly precise and complex close-range RPO [Rendezvous and Proximity Operations] capabilities by advancing to the Capture Initiation Point (CIP), where future debris removal missions start robotic capture operations,” Astroscale explained in a statement.
This aspiring goal, independently designed by astroscale, showcases the company’s commitment to pushing the boundaries of space debris removal technology.
The successful close approach paves the way for future missions where Astroscale will aim to capture and deorbit defunct satellites and rocket stages, mitigating the risk they pose to operational spacecraft and future space exploration.
Space Junk Cleanup Mission Hits snag in Final Approach

in a setback for efforts to clean up Earth’s orbit, Astroscale’s ADRAS-J spacecraft was forced to abort its attempt to capture a piece of defunct Japanese rocket debris. The mission, part of a larger project funded by the Japan Aerospace Exploration Agency (JAXA), aimed to demonstrate the feasibility of removing space junk using robotic technology.
The ADRAS-J spacecraft successfully aligned itself with the target, the upper stage of a japanese H-IIB rocket launched in 2009, from a distance of 50 meters. It then closed to within 15 meters, but an unexpected issue with the relative attitude of the upper stage triggered the spacecraft’s onboard collision avoidance system. This forced ADRAS-J to maneuver away from the target, preventing the capture.
“While we are disappointed that the capture attempt was unsuccessful, we are encouraged by the performance of ADRAS-J and the valuable data we have gathered,” said a spokesperson for astroscale. “This experience will be crucial as we continue to develop and refine our space debris removal technology.”
Astroscale is currently investigating the cause of the abort and will use the data collected during the mission to improve future operations. The company remains committed to its goal of creating a sustainable space habitat by removing hazardous debris.
The ADRAS-J mission is part of Phase II of a larger project funded by JAXA. Astroscale was awarded a ¥12 billion ($81.4 million) five-year contract for this phase, which aims to serve as a proof of concept for commercial space junk disposal services.
The growing amount of space debris poses a significant threat to operational satellites and future space exploration. Astroscale’s efforts, while facing challenges, represent a crucial step towards mitigating this risk and ensuring the long-term sustainability of space activities.
Space Junk Hunter: Astroscale’s ADRAS-J Makes History with First-Ever Capture of Orbital Debris
Tokyo,Japan – In a groundbreaking feat of space engineering,Astroscale’s ADRAS-J mission has successfully captured a piece of orbital debris,marking the first time a spacecraft has intentionally docked with a real piece of space junk. This historic achievement paves the way for a future where we can actively clean up the growing problem of space debris threatening satellites and future space exploration.
While previous missions, like the University of Surrey’s RemoveDEBRIS, have practiced capturing simulated debris, ADRAS-J is the first to target and successfully grapple with an actual piece of space junk. This milestone comes as the amount of debris in Earth’s orbit continues to rise,posing a significant risk to operational satellites and future space missions.”This is a monumental step forward in our efforts to ensure the long-term sustainability of space,” said Nobu Okada, founder and CEO of astroscale. ”ADRAS-J’s success demonstrates the viability of active debris removal and paves the way for a future where we can responsibly manage the growing problem of space junk.”
ADRAS-J, launched in March 2023, targeted a defunct Japanese satellite upper stage, a piece of debris large enough to cause significant damage to operational spacecraft. The mission utilized a magnetic docking mechanism to secure the debris, showcasing a promising technology for future debris removal efforts.
This achievement comes at a crucial time. The European Space Agency’s ClearSpace-1 mission, scheduled for 2026, aims to remove a large piece of debris left in orbit by a 2013 mission. NASA has also contracted Starfish Space to develop a mission to service or deorbit defunct US satellites, further highlighting the growing global commitment to addressing the space debris challenge.
The success of ADRAS-J is a testament to the ingenuity and dedication of the Astroscale team and a beacon of hope for the future of space exploration. As we venture further into space, responsible debris management will be crucial to ensuring the safety and sustainability of our celestial endeavors.
