A Legal Framework Designed for a Different Universe
In September 2024, the Federal Communications Commission's five-year deorbit rule became fully enforceable for new satellite applications. Operators seeking FCC licences for low-Earth orbit missions must now demonstrate credible capability to dispose of their satellites within five years of mission completion — a dramatic tightening from the previous 25-year voluntary guideline that had governed the industry for decades.
The rule is the most significant regulatory intervention in space debris management in the history of commercial spaceflight. It will reshape satellite design, propulsion requirements, insurance underwriting, and mission architecture for every operator seeking access to the American market. And it is, by any honest assessment, insufficient to address the fundamental legal crisis of the orbital commons.
The problem is not that the FCC rule is poorly designed. It is that the rule addresses only the future — new satellites, new missions, new operators — while leaving intact a liability regime built in the 1960s and 1970s that cannot assign fault for existing debris, cannot compel cleanup of objects already in orbit, and cannot resolve the sovereignty paradox that makes active debris removal legally perilous for any operator willing to attempt it.
Understanding why requires a careful examination of the legal architecture that governs space — and an honest reckoning with the gap between what that architecture was designed to do and what the orbital environment of 2026 actually requires.
The Liability Convention's Fundamental Limitation
The 1972 Liability Convention establishes two distinct liability regimes for damage caused by space objects. For damage caused on Earth's surface or to aircraft in flight, launching states bear "absolute liability" — they are responsible regardless of fault. For damage occurring in outer space, the Convention establishes "fault-based liability" — the injured party must prove that the damage resulted from the fault of the launching state or its nationals.
The fault-based standard for in-orbit collisions is, in practice, nearly impossible to satisfy. Identifying which piece of debris caused a collision requires tracking data of sufficient precision to establish provenance — and the orbital environment contains hundreds of thousands of objects too small to track reliably. Even when a collision can be attributed to a specific object, establishing that the launching state was at fault requires demonstrating that the operator failed to meet some standard of care. No such standard has been codified in international law. The Liability Convention demands certainty that the physics of orbital mechanics cannot reliably provide.
"The Liability Convention requires the injured party to prove fault for in-orbit collisions — but identifying which piece of debris caused a collision, and who launched it, is often technically impossible. The law demands certainty that physics cannot provide."
The practical consequence is that there has been no successful precedent for holding a party liable for a space-debris collision under the Liability Convention. The 2009 collision between Iridium 33 and Cosmos 2251 — the first accidental hypervelocity collision between two intact satellites — generated no successful liability claim. The debris field it created, containing thousands of trackable fragments, remains in orbit today. No one has been held legally responsible for the ongoing risk it poses.

The FCC Rule: What It Does and Does Not Do
Against this backdrop, the FCC's five-year deorbit rule represents a meaningful regulatory advance. By requiring operators to demonstrate credible deorbit capability before receiving a licence, the Commission is embedding debris mitigation into the commercial calculus at the design stage rather than treating it as an afterthought. The rule has already influenced mission architecture: operators above 500–600 kilometres, where natural atmospheric decay cannot reliably achieve five-year disposal, must now incorporate active propulsion systems capable of executing controlled reentry.
The insurance market has responded accordingly. Underwriters are increasingly incorporating deorbit compliance into their risk models, with satellites that cannot credibly demonstrate five-year disposal capability facing higher premiums or specific coverage exclusions. This market signal reinforces the regulatory requirement in ways that pure enforcement cannot.
But the rule has significant limitations that its proponents have been candid about. It applies only to FCC-licensed operators — creating a regulatory asymmetry that leaves foreign-licensed competitors operating under different standards. SpaceX's Starlink constellation, which already meets the five-year requirement, benefits from this asymmetry; operators from nations with less stringent domestic frameworks do not face the same compliance burden when accessing the American market through foreign licences.
More fundamentally, the rule addresses only future satellites. The existing debris population — estimated at more than 27,000 trackable objects and hundreds of thousands of smaller fragments — is entirely outside its scope. The FCC can require new operators to clean up after themselves. It cannot compel anyone to clean up the mess that already exists.
The FAA Withdrawal and Regulatory Coordination
The regulatory landscape became more complex in early 2026 when the Federal Aviation Administration withdrew a proposed rule that would have mandated a 25-year post-mission disposal timeline for spacecraft and upper stages. The FAA's withdrawal was driven partly by industry opposition and partly by a recognition that the FCC's more stringent five-year standard had already set the effective baseline for the industry.
The episode illustrates a broader challenge in space regulation: the fragmentation of authority across multiple agencies — the FCC, FAA, NASA, the Department of Commerce, and the Department of Defense — creates coordination challenges that can produce regulatory gaps, overlaps, and inconsistencies. The United States has not yet established a single regulatory authority for commercial space activities, and the absence of such an authority complicates both domestic enforcement and international coordination.
The Sovereignty Paradox: Why Cleanup Is Legally Dangerous
The most intractable problem in space debris law is not the absence of rules about creating debris — it is the legal framework that governs what happens to debris once it exists. Article VIII of the Outer Space Treaty establishes that states retain jurisdiction and control over their space objects, and that ownership of objects launched into space is not affected by their presence in outer space or on a celestial body.
Perpetual ownership of space objects, enshrined in Article VIII of the Outer Space Treaty, is the legal provision that makes the orbital commons a tragedy waiting to happen. You cannot clean up what you do not own, and you cannot touch what someone else does.
This provision of perpetual ownership creates what legal scholars have called the "sovereignty paradox" of active debris removal. If a defunct satellite belongs permanently to the state that launched it, then any attempt by another operator to remove, move, or interact with that satellite without explicit consent could be interpreted as a violation of the launching state's sovereign rights over its space object. The operator attempting to clean up the orbital commons faces potential liability under the very treaty that was supposed to govern responsible behaviour in space.
"Perpetual ownership of space objects, enshrined in Article VIII of the Outer Space Treaty, is the legal provision that makes the orbital commons a tragedy waiting to happen. You cannot clean up what you do not own, and you cannot touch what someone else does."
The Liability Convention compounds this problem. If an active debris removal operator accidentally damages another country's satellite during a cleanup operation, the Convention holds the cleanup operator absolutely liable for the damage. The legal exposure for attempting to improve the orbital environment can exceed the legal exposure for contributing to its degradation.
Several legal scholars and policy analysts have proposed treating abandoned space objects as "abandoned property" — a status that would allow other operators to remove them without triggering sovereignty concerns. The Chicago Journal of International Law has published analysis arguing that this approach is consistent with the OST's text, which speaks of "jurisdiction and control" rather than permanent ownership in the conventional sense. But this interpretation has not been adopted by any major space power, and the legal uncertainty it would resolve is precisely the kind of uncertainty that states are reluctant to resolve in ways that might limit their future options.
Market-Based Approaches and Their Limits
In the absence of binding international law, several market-based approaches to debris management have been proposed. Cap-and-trade models would assign debris credits to operators, creating financial incentives for cleanup. Market-share liability regimes would hold operators collectively responsible for debris proportional to their share of the orbital population. Insurance mandates would require operators to carry coverage for debris-related damage, creating actuarial pressure for better debris management.
Each of these approaches has merit as a complement to regulatory requirements. But each also has limitations that prevent it from serving as a substitute for binding international law. Cap-and-trade requires a regulatory authority with jurisdiction over all operators — which does not exist at the international level. Market-share liability requires a legal framework for attributing debris to specific operators — which the current tracking infrastructure cannot reliably support. Insurance mandates require insurers willing to underwrite debris risk at scale — which the market has been reluctant to do given the difficulty of pricing tail risks in the orbital environment.
The ESA's Zero Debris Charter, which commits signatories to achieving zero debris generation from space missions by 2030, represents a voluntary industry initiative that has attracted significant participation. But voluntary commitments, however well-intentioned, cannot substitute for the binding enforcement mechanisms that the orbital commons ultimately requires.
The Enforcement Gap: From $150,000 Fines to Real Deterrence
The FCC's 2023 enforcement action against Dish Network — a $150,000 fine for failure to properly deorbit a geostationary satellite — was celebrated as a landmark: the first debris-related enforcement action in the history of commercial spaceflight. It was also, by any measure of the actual risk posed by an improperly deorbited geostationary satellite, a rounding error.

Effective deterrence requires that the cost of non-compliance exceed the cost of compliance. For large commercial operators, a $150,000 fine is a cost of doing business, not a meaningful deterrent. The FCC has not yet established a formal penalty schedule for non-compliance with the five-year deorbit rule, and the enforcement strategy for the new regime remains under development.
International enforcement is even more challenging. The Liability Convention provides a mechanism for states to bring claims against other states for damage caused by their space objects — but the process is diplomatic rather than judicial, and no successful claim has ever been brought under the Convention for in-orbit damage. The absence of an international tribunal with jurisdiction over space debris disputes — analogous to the International Tribunal for the Law of the Sea for maritime disputes — means that enforcement depends entirely on diplomatic pressure and bilateral negotiation.
What a Functional Legal Regime Would Require
The gap between the legal framework that currently governs the orbital commons and the framework that the commercial space era requires is substantial. A functional regime would need to address at minimum: clear standards of care for debris mitigation that can support fault-based liability claims; a mechanism for assigning responsibility for existing debris to specific operators or states; legal clarity on the status of abandoned space objects that enables active debris removal; binding dispute resolution mechanisms with jurisdiction over in-orbit incidents; and enforcement authority that applies to all operators regardless of national licensing.
None of these elements exists in current international law. The Outer Space Treaty provides foundational principles but not operational rules. The Liability Convention provides a liability mechanism but not one that functions effectively for in-orbit incidents. The FCC rule provides meaningful domestic regulation but not international coverage.
The most likely path to a more functional regime runs through the UN COPUOS process — the same multilateral forum that has been working on space governance for decades. COPUOS has produced voluntary guidelines for long-term sustainability of outer space activities that represent the current international consensus on debris mitigation best practices. Elevating those guidelines to binding treaty obligations would require the kind of political will that has historically been difficult to mobilise for space governance — but the alternative is a continued race between the growth of the debris population and the inadequacy of the legal framework designed to manage it.
The Orbital Commons as a Test Case for Global Governance
The orbital debris problem is, at its core, a classic commons governance challenge: a shared resource being degraded by individual actors whose incentives do not align with the collective interest in preserving it. The history of commons governance on Earth — from fisheries to the atmosphere — suggests that voluntary measures and market incentives are necessary but not sufficient. Binding rules with effective enforcement are ultimately required.
The FCC's five-year deorbit rule is a meaningful step in the right direction. It demonstrates that regulatory intervention can change commercial behaviour, that market signals can reinforce regulatory requirements, and that enforcement — even imperfect enforcement — matters. But it is a domestic rule in a domain that is inherently international, addressing future satellites in an environment already crowded with the debris of the past.
The orbital commons will not be saved by any single regulatory intervention. It will be saved — if it is saved — by the construction of a legal architecture that matches the scale and complexity of the commercial space era: binding international standards, effective enforcement mechanisms, legal clarity on debris removal, and the political will to treat the orbital environment as the shared infrastructure that it is. The FCC rule is a beginning. The work of building that architecture has barely started.
