Space Debris Regulations by Country: A Global Comparison

Space debris is the defining environmental challenge of the orbital age. With over 36,000 tracked objects larger than 10 cm in orbit and an estimated 130 million fragments smaller than 1 cm, the risk of cascading collisions, known as Kessler Syndrome, is no longer theoretical. Governments worldwide are responding with increasingly stringent debris mitigation regulations, but the approaches vary significantly by jurisdiction.

For satellite operators, launch providers, and space startups, understanding these regulatory differences is critical. Operating across borders means complying with multiple debris frameworks simultaneously. Here is how six major spacefaring nations and regions approach the problem.

United States: The FCC 5-Year Rule

The United States has adopted the most aggressive timeline for post-mission disposal. In September 2022, the FCC adopted a new rule requiring satellites in low Earth orbit (LEO) to deorbit within 5 years of mission completion, a dramatic reduction from the previous 25-year guideline established by NASA and the Inter-Agency Space Debris Coordination Committee (IADC).

Key U.S. Requirements

• FCC: 5-year post-mission disposal rule for LEO satellites (effective September 2024). Applies to all FCC-licensed or market-access-granted satellites.
• FAA: Requires orbital debris assessment reports (ODAR) as part of launch licensing. Flight termination systems mandated for launch vehicles.
• NASA: NASA-STD-8719.14B sets agency debris requirements including collision avoidance, passivation, and end-of-life planning.
• FCC orbital debris mitigation order: Requires operators to disclose casualty risk assessments, maneuverability, trackability, and planned disposal orbits.
• NTIA guidelines: Voluntary best practices for government and commercial operators.

The FCC's move from 25 years to 5 years was controversial. Industry groups including the Satellite Industry Association argued the rule would increase costs for smaller operators. The FCC countered that the growing congestion in LEO demanded faster action. With over 8,000 Starlink satellites already in orbit and Amazon's Kuiper constellation deploying, the math supports the FCC's urgency.

European Union: The ESA Zero Debris Charter

The European Space Agency (ESA) set out its Zero Debris approach in 2023, and the Zero Debris Charter opened for signature in 2024, setting a goal of eliminating new debris generation by 2030. ESA is not a regulatory body (member states retain licensing authority), and the Charter is a non-binding commitment: it signals intent, but signatories are not legally bound by it.

Key EU/ESA Requirements

• ESA Zero Debris Charter: Signatories commit to zero debris generation by 2030, including 99% post-mission disposal success rate.
• CNES (France) debris requirements: France mandates debris mitigation through the French Space Operations Act (see below).
• EU Space Surveillance and Tracking (SST): EU-wide collision avoidance services operated through EUSST consortium.
• ESA Space Debris Mitigation Requirements: ESA/ADMIN/IPOL(2023)15 sets requirements for all ESA missions, including passivation, controlled reentry, and disposal orbit compliance.

Europe's approach emphasizes industry commitment over regulatory mandate. The Zero Debris Charter has been signed by major European operators, manufacturers, and agencies. Whether voluntary commitments achieve the same compliance rates as regulatory mandates remains an open question.

France: The Space Operations Act

France has the most comprehensive national space debris law of any country. The Loi relative aux Operations Spatiales (LOS), enacted in 2008 with implementing decrees in 2010, establishes legally binding debris mitigation requirements for all French-licensed space operations.

Key French Requirements

• Mandatory debris mitigation plan: All operators must submit a detailed debris mitigation plan for CNES review and approval.
• 25-year disposal rule: LEO satellites must deorbit within 25 years of end of mission (predates the FCC's 5-year rule).
• Passivation requirements: All stored energy (propellant, batteries, reaction wheels) must be depleted at end of life to prevent explosions.
• Third-party liability: Operators must carry insurance covering third-party damage from debris.
• CNES Technical Authority: CNES reviews all debris mitigation plans and can impose additional requirements.

France's law is notable because it established legally binding debris requirements at a time when most countries relied on voluntary guidelines. The LOS has served as a model for other nations drafting space legislation.

United Kingdom: The Space Industry Act 2018

The UK overhauled its space regulatory framework with the Space Industry Act 2018, replacing aspects of the Outer Space Act 1986. The Civil Aviation Authority (CAA) now serves as the primary regulator for UK spaceflight activities.

Key UK Requirements

• Outer Space Act 1986: Requires licensing for all UK nationals and entities conducting space activities. License conditions include debris mitigation obligations.
• Space Industry Act 2018: Adds regulatory framework for launches from UK soil and suborbital activities.
• CAA licensing conditions: Operators must demonstrate debris mitigation compliance, including end-of-life disposal plans.
• UK Space Agency sustainability guidelines: Promotes adoption of international debris mitigation guidelines (IADC, ISO 24113).
• Plan for Orbital Sustainability: The UK's 2024 plan sets out national objectives for long-term orbital sustainability.

The UK's approach balances regulatory requirements with its goal of becoming a leading launch nation. Licensing conditions are applied case-by-case, giving regulators flexibility but creating less predictability for operators compared to France's prescriptive approach.

Japan: Space Activities Act

Japan enacted its Space Activities Act in 2016, establishing a licensing framework that includes debris mitigation requirements. The Cabinet Office oversees space policy, while the Ministry of Economy, Trade and Industry (METI) handles certain regulatory functions.

Key Japanese Requirements

• Space Activities Act 2016: Requires debris mitigation measures as a condition of satellite operation licenses.
• JAXA debris mitigation standards: JAXA applies debris mitigation standards based on IADC guidelines to all its missions.
• End-of-life disposal: Operators must demonstrate post-mission disposal capability in their license applications.
• Active debris removal research: Japan is a leader in ADR technology development, with JAXA's CRD2 program and commercial initiatives like Astroscale's ELSA-d and ADRAS-J missions.

Japan stands out for its investment in active debris removal (ADR) technology. Astroscale, a Tokyo-based company, has conducted the most advanced commercial ADR demonstrations to date with its ADRAS-J mission successfully rendezvousing with a defunct upper stage in 2024.

China: Emerging Framework

China's space debris regulatory framework is still developing. While China is a signatory to the UN COPUOS Space Debris Mitigation Guidelines and participates in the IADC, its domestic regulatory requirements are less transparent than Western frameworks.

Key Chinese Provisions

• Space Debris Mitigation Requirements (2010): Internal requirements issued by CNSA for Chinese government missions.
• China National Space Administration (CNSA) guidelines: CNSA applies debris mitigation standards to state-sponsored missions.
• Commercial space licensing: China's emerging commercial space sector (Landspace, Galactic Energy, SpaceSail) operates under evolving regulatory requirements that include some debris provisions.
• Space Debris Action Plan: China has committed to improved debris tracking and mitigation through IADC participation.

China's 2007 anti-satellite test, which created over 3,500 trackable debris fragments (many still in orbit today), remains a source of international concern. More recently, China's rapid deployment of commercial LEO constellations has raised questions about debris management practices in the absence of detailed public regulations.

Regulatory Comparison Summary

Key differences across jurisdictions:

• Disposal timeline: The US (FCC) mandates 5 years; France and most others follow the 25-year IADC guideline; ESA targets zero debris by 2030.
• Legal force: France and the US have binding regulations; UK uses license conditions; ESA relies on voluntary charter; Japan uses licensing requirements; China's framework is less publicly defined.
• Scope: The FCC rule applies to all satellites seeking US market access (not just US-licensed satellites), giving it extraterritorial reach. France's law applies to French-licensed operations. The UK covers all UK nationals globally.
• Insurance: France requires debris liability insurance; the US requires third-party liability insurance for launches but not specifically debris insurance; the UK requires insurance as a license condition.
• Active debris removal: Japan leads in ADR technology investment. ESA is funding ADR missions (ClearSpace-1). The US has provided government contracts for ADR studies. No country mandates ADR participation.

What's Next: Convergence or Fragmentation?

The trend is toward stricter requirements globally. The FCC's 5-year rule is likely to influence other regulators. ESA's Zero Debris Charter pushes European operators toward even more ambitious targets. The UN Committee on the Peaceful Uses of Outer Space (COPUOS) continues working toward updated international guidelines.

For multi-national operators, the challenge is navigating a patchwork of requirements. A constellation with satellites licensed in the US, launched from New Zealand, and providing service in Europe must comply with all applicable debris frameworks simultaneously.
