Scientists Urge Circular Space Economy to Tackle Debris and Launch Pollution

A paper in Chem Circularity outlines reusable design, in‑orbit repair, debris recovery, AI tracking, plus international rules to shift space operations.

Overview

  • A multidisciplinary team led by University of Surrey engineer Jin Xuan published the framework on December 1, calling for a system-wide transition across spacecraft design, operations, and retirement.
  • Citing iScience data, the authors note debris stems primarily from fragmentation events at 65%, followed by decommissioned spacecraft and rocket bodies at 30%, and mission-related objects at 5%.
  • Recommendations include durable, modular, repairable spacecraft; space stations repurposed as refueling and maintenance hubs; and in‑orbit manufacturing to reduce the number of launches.
  • The paper urges soft‑landing technologies to enable component recovery plus active debris capture using nets or robotic arms to recycle materials and lower collision risks.
  • The authors highlight AI-enabled tracking, data analysis, and simulation to prevent collisions and cut physical testing, alongside calls for international policy frameworks to incentivize reuse and recovery.
