Orbital Debris Coordination and Removal
Low Earth orbit is becoming a tragedy of the commons. Debris accumulates faster than governance, raising collision risk and threatening satellites, science, and future missions.
The Stakes
Space is now critical infrastructure: communications, navigation, remote sensing, and defense. If orbital regimes become too risky, we lose capability and raise costs for everything that depends on space services. This is a coordination problem with a physics-based tipping risk: collisions create more debris, increasing future collision probability.
Headline evidence
- •ESA reports roughly 35,000 objects are tracked in orbit, with about 26,000 pieces of debris larger than 10 cm. [1]
- •The Inter-Agency Space Debris Coordination Committee reports an estimated environment including about 34,000 objects larger than 10 cm, about 900,000 objects from 1–10 cm, and about 128 million objects from 1 mm–1 cm. [2]
- •A NASA deorbit technology state-of-the-art report cites debris population estimates including roughly 1.1 million objects 1–10 cm and over 36,500 pieces larger than 10 cm. [3]
Neglectedness
Why it stays neglected
No one owns orbit. The cost of bad behavior is distributed across all operators over time. Standards exist, but enforcement is weak and international coordination is slow. Meanwhile, launch costs dropped and deployment accelerated, outpacing governance.
Tractability
Active debris removal is hard but becoming feasible. The tractable near-term wedge is coordination and verification: better tracking, collision avoidance interoperability, faster deorbit compliance, and insurance mechanisms that price risk properly. Removal missions can start with high-risk large objects where marginal benefit is highest.
Startup surfaces
- •High-precision tracking and conjunction analysis for small operators
- •Interoperable collision avoidance protocols and operator-to-operator coordination tooling
- •Deorbit compliance monitoring and scoring for insurers and regulators
- •“Removal as a service” targeting high-risk derelicts with verification of disposal
- •Space traffic data infrastructure with reconciled catalogs and uncertainty estimates
