Space debris threatens orbital infrastructure critical for global navigation, telecommunications, and climate monitoring. Over 44,870 objects are tracked by space surveillance networks, with total mass exceeding 15,800 tonnes in Earth orbit.
A World Economic Forum report projects cumulative economic losses of $25.8 billion to $42.3 billion over the next decade without intervention. These costs break down to $14.7–26.3 billion from service disruptions, $10.5–15.5 billion from asset losses, and $0.56 billion from collision-avoidance maneuvers. High-risk bands at 800–1,000 km altitudes see fragments persisting for centuries, with collision probabilities in debris clusters reaching 29% by 2032.
Active debris removal (ADR) missions address this congestion. The UK Space Agency reviews designs from Astroscale and ClearSpace for a 2026 mission to de-orbit two derelict low Earth orbit satellites under UK licenses. Astroscale adapts magnetic docking from ELSA-d and ELSA-M missions, while ClearSpace employs four robotic arms, building on its ESA-funded ClearSpace-1 targeting a 2013 Vega rocket adapter launching via Arianespace Vega-C no earlier than early 2026.
Space situational awareness (SSA) enables these efforts through precise tracking of debris location, tumbling behavior, and nearby objects. Optical networks and AI analytics forecast motions affected by drag or pressure, supporting robotic arms, nets, harpoons, or drag sails for capture and de-orbit. Over 650 fragmentation events have occurred since 1957, underscoring the need for sustained remediation to prevent Kessler Syndrome and protect $190 billion in satellite assets.
