There Is No Liability Mechanism That Makes Anyone Pay to Remove the Orbital Debris They Created
Problem Definition
Here is the specific, unsolved problem, stripped of the "space is getting crowded" hand-waving: there is no functioning liability-and-payment mechanism that makes the entity creating orbital debris bear the cost of removing it, and without that mechanism, active debris removal (ADR) will never scale to match the rate of debris generation, no matter how good the tracking gets.
Walk through the numbers. 8 km/s. 16101) shows that even if all new launches stopped today, the debris population keeps growing for more than 200 years, because fragmentation events (collisions, explosions of residual propellant, material degradation) generate new debris faster than atmospheric drag removes it in the shells above roughly 600 km.
This is the Kessler syndrome not as a thought experiment but as a boundary condition already showing up in some LEO altitude bands.
The mitigation guidelines that exist — the 25-year post-mission deorbit rule, ESA's tightened 5-year internal standard, the FCC's 2024 domestic rule — are prospective and non-binding across jurisdictions. They tell new missions what to do with their own hardware going forward.
None of them address the roughly 40,000 already-tracked defunct objects and their untracked fragmentation products currently occupying valuable orbital shells, because nobody owns the liability for removing something that was launched decades ago, often by an entity that no longer exists in its original form, under a regulatory regime that predates the rule.
Active debris removal missions exist as technology demonstrations — robotic arms, harpoons, magnetic capture, net systems — and cost tens of millions of dollars per object retrieved.
Without a market or treaty mechanism assigning cost recovery (a launching state fund, an insurance-style pooled liability system, a Coasean bargain enforced by an international body with actual teeth), ADR remains a philanthropic or single-government-funded curiosity rather than an industry.
The 1972 Liability Convention assigns fault-based liability for damage caused by space objects, but it was written for isolated collision incidents between identifiable objects, not for a diffuse, decades-accumulated debris field where causal attribution to a specific launching state is often impossible for older fragments.
This is a governance and market-design failure sitting on top of a physics problem, and the physics problem does not wait for the governance to catch up.
Root Causes
No retroactive liability regime: the 1972 Liability Convention and post-mission disposal guidelines are fault-based and prospective, leaving legacy debris (much of it decades old, with unclear or defunct ownership) as an orphaned liability nobody is obligated to fund removal for.
Misaligned incentives at launch time: operators bear the cost of disposal compliance for their own hardware but capture none of the benefit of a cleaner shared orbital commons, so compliance is treated as a regulatory cost to minimize rather than an investment in collective orbital capacity.
No pricing mechanism for orbital carrying capacity: unlike other shared-resource problems (carbon markets, fisheries quotas), there is no tradable permit, tax, or insurance-pooled cost structure that prices the marginal risk each new object adds to the debris field, so launch volume keeps growing faster than disposal capacity.
Fragmented, non-binding international enforcement: guidelines from ESA, the FCC, and UN COPUOS each bind only their own licensees or members, so a global commons problem is being managed through a patchwork of jurisdiction-specific rules with no shared enforcement body or penalty structure for non-compliance.

Until launch licensing regimes mandate upfront salvage bonds, low Earth orbit will remain an unpriced commons where externalizing cleanup costs is the only economically rational move.
