Introduction
The commercial space sector is undergoing a significant shift. Lower launch costs and technological advancements have led to a surge in satellite deployments, particularly in Low Earth Orbit. This rapid expansion presents economic opportunities but also introduces risks regarding orbital congestion, cybersecurity threats, and environmental impacts. The European Union has proposed the Regulation on the safety, resilience, and sustainability of space activities, commonly known as the EU Space Act, to address these challenges. This legislation seeks to harmonize rules across the internal market, ensuring that space activities are conducted safely and sustainably while preserving the competitiveness of the European space industry.
The Context of the New Space Era
The space sector was historically dominated by state actors and a few large industrial players. Today, the landscape involves a diverse array of private companies, startups, and academic institutions. This phenomenon, often termed “New Space,” has democratized access to orbit but has also complicated the regulatory environment. Member States within the European Union have begun enacting national space laws to fulfill their obligations under the United Nations Outer Space Treaty. However, these national approaches vary significantly in their technical requirements and administrative procedures.
Diverging national rules create fragmentation within the internal market. A spacecraft operator authorized in one Member State might face different safety requirements than a competitor in another. This lack of uniformity can hinder cross-border operations, disrupt the supply chain, and create uncertainty for investors. The EU Space Act intends to replace this patchwork of regulations with a unified framework. It establishes common rules for the authorization of space activities, the registration of space objects, and the supervision of operators. By doing so, the regulation facilitates the free movement of space-based data and services throughout the Union.
Scope and Applicability of the Regulation
The regulation applies broadly to space services providers. This encompasses space operators, which include those who maneuver spacecraft, launch operators, and providers of in-space operations and services. It also extends to primary providers of space-based data – intermediaries that channel raw or processed data from satellites to downstream users.
The geographical reach of the regulation is significant. It covers Union space operators, defined as entities established in the Union or launching from Union territory. It also captures third-country space operators if they provide space services or data within the Union. This extraterritorial dimension ensures a level playing field, preventing companies from circumventing EU safety and sustainability standards by establishing themselves in jurisdictions with laxer regulations.
Specific exclusions exist to preserve national sovereignty and security. Space objects used exclusively for defense or national security are outside the scope of the regulation. Assets that are partially used for defense purposes may also be excluded for the duration of specific military operations. Furthermore, the regulation does not interfere with the management of radio spectrum, which remains governed by existing international and Union telecommunications frameworks.
Authorization and Supervision Governance
A central component of the legislation is the establishment of a standardized authorization process. Space activities requires an EU Space Act (EUSA) authorization. The authority responsible for issuing this authorization depends on the nature of the operator and the asset.
For Union-owned assets, such as those belonging to the EU Space Programme (e.g., Galileo or Copernicus), the European Commission serves as the authorizing authority. For all other governmental and non-governmental assets, the National Competent Authorities (NCAs) of the Member States are responsible. Member States must designate these authorities and ensure they possess the necessary independence and technical expertise.
The European Union Agency for the Space Programme (EUSPA) plays a reinforced role in this governance structure. The regulation establishes a Compliance Board within the Agency. This board is tasked with providing technical assessments and opinions to the Commission regarding Union-owned assets and third-country operators. It also supports Member States that choose to entrust the Agency with technical assessments for their national operators.
Qualified Technical Bodies
Given the technical complexity of space missions, the regulation relies on Qualified Technical Bodies (QTBs). These entities are responsible for assessing whether a space operator’s plans meet the stringent safety and sustainability requirements of the Act. QTBs can be national bodies, the Agency itself, or international organizations with specific expertise, such as the European Space Agency (ESA). These bodies review technical files, verify calculations regarding collision risks and debris generation, and issue opinions that inform the final authorization decision.
The Union Repository and E-Certificate
To ensure transparency and traceability, the Agency will manage a Union Repository of Space Activities (URSA). This centralized database will list all authorized space activities, including the operator’s details, the space objects involved, and the duration of the mission.
Upon registration in URSA, operators receive an electronic certificate, or e-certificate. This digital document serves as proof of compliance with the EU Space Act. It allows the free provision of space-based data and services across the internal market. The e-certificate is particularly relevant for downstream data providers, who must ensure that the data they distribute originates from compliant, safe, and sustainable space operations.
Pillar 1: Safety of Space Activities
Safety constitutes the first pillar of the regulation, addressing the physical risks associated with launching, operating, and disposing of space objects.
Launch Safety and Traffic Management
Launch activities are inherently hazardous. The regulation mandates that Union launch operators submit a Launch Safety Plan. This plan must demonstrate coordination with air and maritime traffic authorities to minimize disruption and safety risks during launch and re-entry windows.
A mandatory Launch Collision Avoidance (LCOLA) analysis is required before any launch. This assessment calculates the probability of the launch vehicle colliding with existing space objects. The regulation empowers the Commission to select or develop specific calculation methods and set probability thresholds. If the risk exceeds these thresholds, the launch window must be adjusted.
Collision Avoidance in Orbit
Once in orbit, spacecraft must be trackable. Operators are required to ensure their assets can be monitored by ground-based surveillance systems. For orbits above 400 km, spacecraft must possess maneuverability capabilities. This allows them to perform collision avoidance maneuvers in response to High Interest Events (HIE) – situations where the probability of impact with another object is significant.
Subscription to a collision avoidance service is mandatory. Operators must use the services provided by the Union Collision Avoidance entity (part of the EU Space Surveillance and Tracking partnership) or a certified third-party provider. The legislation outlines specific rules for orbital traffic management. In the event of a conjunction between two active satellites, operators must coordinate their maneuvers. If they cannot agree, the Union CA entity will recommend a strategy based on principles such as protecting crewed vehicles and minimizing secondary risks.
Constellations and Mega-Constellations
The rise of satellite constellations requires specific regulatory attention. The Act distinguishes between smaller constellations and “mega-constellations” (defined as consisting of 101 or more satellites). Large constellations face stricter requirements regarding orbital selection to prevent congestion. Operators must demonstrate that their deployment will not create unacceptable collision risks or interfere with existing constellations. They must also implement automated collision avoidance processes and ensure that their satellites can be de-orbited quickly at the end of their lives to clear valuable orbital slots.
Pillar 2: Resilience and Cybersecurity
The second pillar focuses on the resilience of space infrastructure. Space assets are increasingly integrated into critical economic sectors, making them attractive targets for cyberattacks. The regulation aligns with the NIS2 Directive, which sets cybersecurity baselines for critical infrastructure in the Union.
Space operators must implement robust risk management measures. These include supply chain security, encryption of command and control links, and incident response plans. The regulation acknowledges the specific vulnerabilities of the space sector, such as the impossibility of physical access to orbital assets for repairs. Therefore, “security by design” is a fundamental requirement.
Reporting obligations are established for significant incidents. Operators must notify competent authorities of any event that compromises the availability, integrity, or confidentiality of their services. This information is shared through the European network of Computer Security Incident Response Teams (CSIRTs) to facilitate a coordinated defense against cyber threats.
Pillar 3: Environmental Sustainability
The third pillar addresses the environmental impact of space activities, covering both the space environment (orbital debris) and the Earth environment (carbon footprint).
Space Debris Mitigation
Space debris poses a severe threat to the long-term usability of Earth’s orbits, a scenario known as the Kessler syndrome. The Act imposes strict debris mitigation measures. Operators must design spacecraft to limit the release of debris during normal operations.
End-of-life disposal is strictly regulated. For satellites in Low Earth orbit (LEO), the preferred disposal method is controlled re-entry into the Earth’s atmosphere, where the satellite burns up. If this is not feasible, uncontrolled re-entry or placement in a decay orbit (where atmospheric drag will naturally de-orbit the object within a specific timeframe, typically 5 or 25 years depending on the specific implementing act) is permitted, provided the casualty risk on the ground is below a defined threshold.
Passivation is another requirement. At the end of a mission, operators must deplete all onboard energy sources, such as batteries and fuel tanks, to prevent accidental explosions that could generate thousands of new debris fragments.
Environmental Footprint on Earth
The regulation introduces a requirement to calculate the Environmental Footprint (EF) of space activities. This Life Cycle Assessment (LCA) covers the entire mission, from the manufacturing of the satellite and launcher to the emissions generated during launch and the eventual disposal. The Commission will establish a standardized methodology for these calculations. While this does not currently impose limits on emissions, the mandatory reporting creates transparency and encourages industry to adopt greener technologies.
Dark and Quiet Skies
A unique aspect of the regulation is the protection of the “Dark and Quiet Sky.” Large satellite constellations can interfere with astronomical observations by reflecting sunlight (light pollution) or emitting radio signals that disrupt radio astronomy. Operators are required to have a plan to minimize these disturbances, for example, by using low-reflectivity coatings or adjusting orbital attitudes.
In-Space Operations and Services (ISOS)
The regulation looks forward to the emerging market of In-Space Operations and Services (ISOS). This includes activities such as satellite refueling, repair, assembly in orbit, and active debris removal. These complex operations involve close-proximity maneuvers that carry high collision risks.
From 2034, specific rules for ISOS will apply. Spacecraft above a certain weight threshold will be required to be equipped with a Spacecraft Service Interface (SSI) – a standard docking port that facilitates servicing. The Commission will adopt technical standards for these interfaces. This mandate promotes interoperability and ensures that future satellites can be serviced or removed if they fail, rather than becoming permanent debris.
International Relations and Third Countries
Space is an inherently global domain. The EU Space Act includes mechanisms to engage with international partners. The Commission can issue equivalence decisions, recognizing that a third country’s regulatory framework offers a level of safety and sustainability comparable to the EU’s. Operators from these equivalent jurisdictions can register their activities in the EU more easily.
In the absence of an equivalence decision, third-country operators wishing to provide services in the EU must undergo a full technical assessment by the Agency to demonstrate compliance. This ensures that the high standards imposed on European industry do not result in a competitive disadvantage against foreign operators subject to weaker rules.
The regulation also addresses the role of international organizations. The Union seeks to conclude agreements with organizations like EUMETSAT and the European Space Agency to align their operations with the Act’s requirements. Since ESA is an intergovernmental organization independent of the EU, specific legal instruments are necessary to apply these rules to ESA-operated assets.
Support for Innovation and Light Regimes
Recognizing that strict regulations can burden smaller entities, the Act includes provisions to support innovation. A “light regime” is available for research and education institutions, as well as Small and Medium-sized Enterprises (SMEs). This regime exempts eligible low-risk missions from some of the more capital-intensive requirements, such as adding propulsion systems for maneuverability in very low orbits or conducting extensive environmental footprint assessments.
To further incentivize high standards, the Commission will develop a voluntary Union Space Label. This label will grade space missions on their sustainability and safety performance (e.g., Gold, Silver, Bronze). This market-based mechanism encourages operators to exceed the minimum regulatory baseline, offering them reputational benefits and potentially preferential treatment in public procurement.
| Category | Union Space Operators | Third-Country Operators | Research & SMEs |
|---|---|---|---|
| Authorization | Required via NCA or Commission | Registration via Agency required | Simplified authorization |
| Collision Avoidance | Mandatory subscription to CA service | Must use equivalent service | Assistance provided by Union CA |
| Debris Mitigation | Full compliance required | Equivalent compliance required | Exemptions for short LEO missions |
| Cybersecurity | NIS2 + Space specific rules | Equivalent security required | Light regime for specific risks |
| Env. Footprint | Mandatory calculation & report | Mandatory if selling in EU | Exempted or delayed application |
Summary
The EU Space Act represents a maturing of space law in Europe. By moving from a collection of national rules to a harmonized Union-wide regulation, the EU attempts to create a single market for space services. The legislation balances the need for rigorous safety and sustainability standards with the necessity of maintaining a competitive industrial base. Through its three pillars of safety, resilience, and sustainability, the Act addresses the immediate risks of orbital congestion and cyber threats while laying the groundwork for the future space economy, including in-orbit servicing and active debris removal. The success of this framework will depend on its implementation, particularly the efficient functioning of the Union Repository, the technical capacity of the Agency, and the global acceptance of these new European standards.

What is the difference between LEO and GEO requirements?
Low Earth orbit (LEO) satellites generally require re-entry into the atmosphere for disposal to clear the orbit. Satellites in Geostationary orbit (GEO) must be moved to a “graveyard orbit” approximately 300 km above the active belt to avoid collisions.
How long does a satellite stay in orbit?
A satellite’s orbital lifetime depends on its altitude and mass; the Act regulates this by mandating disposal timeframes. For LEO, satellites must typically de-orbit within a specific period (often 5 to 25 years) after their mission ends to prevent debris accumulation.
What are the benefits of the EU Space Label?
The voluntary Union Space Label allows operators to demonstrate superior safety and sustainability standards. Achieving a high label rating can enhance a company’s reputation and provide advantages in obtaining contracts and financing.
What is the Kessler Syndrome?
The Kessler syndrome is a theoretical scenario where the density of objects in LEO becomes so high that collisions between objects cause a cascade, generating more debris and increasing the likelihood of further collisions. The EU Space Act aims to prevent this through strict mitigation rules.
How does satellite collision avoidance work?
Operators subscribe to services that track space objects and calculate collision probabilities. If a risk is detected, the satellite uses its onboard propulsion to perform a maneuver, altering its trajectory to avoid the object.
What is a mega-constellation?
The Act defines a mega-constellation as a system consisting of 101 or more satellites working together. These systems face enhanced regulatory requirements due to their significant impact on orbital traffic and the environment.
Why is space cybersecurity important?
Satellites control critical infrastructure like GPS, banking timing, and communications. A cyberattack could disrupt these essential services or result in the loss of control of a satellite, turning it into a dangerous projectile.
What happens if a space operator fails to comply?
National authorities or the Commission can impose administrative fines and penalties. In severe cases, they can suspend or withdraw the authorization or registration, effectively banning the operator from the EU market.
Does the EU Space Act cover military satellites?
No, the regulation explicitly excludes space objects used exclusively for defense or national security purposes. However, dual-use assets (civilian and military) may fall under the regulation depending on their primary operation and control.
What is the role of EUSPA in this regulation?
The European Union Agency for the Space Programme (EUSPA) manages the central repository (URSA), issues e-certificates, and provides technical assessments through its Compliance Board to support authorization decisions.
