Space Law 2026 Comparisons

In 2026, the most relevant regulatory development at the European Union level is the ongoing effort to approve a common regulation that would cover some essential aspects of space activities – the EU Space Act. Formally launched in June 2025, the draft is presently being discussed at various EU bodies and has caught the attention of the industry and the public. These efforts go hand in hand with other legislative initiatives to regulate areas which are closely linked to space, such as artificial intelligence, controls on foreign direct investments, and the development of dual-use materials.

At the Spanish level, efforts are under way to prepare a domestic Space Act (Ley del Espacio), a first draft of which was submitted for public scrutiny and comments in late 2025.

The Spanish public authorities are fostering the development of the space economy at all levels, particularly in the light of upcoming geopolitical challenges. In this connection, public grants and subsidies are being offered, government support for new initiatives and start-ups is available and, generally, efforts are being undertaken to attract investment in this area. From a legal perspective, however, the absence of a unified or harmonised regulatory environment presents challenges to a good number of projects. It is anticipated that legislative initiatives such as the EU Space Act and the Spanish Space Act will help in clarifying the regulatory landscape and overcoming bureaucratic hurdles.

By 2020, the aerospace sector already represented 1.2% of Spain’s GDP, with more than 150,000 direct and indirect jobs and more than EUR1.5 billion invested in research, development and innovation (RD&I). In 2022, Spain was positioned as the fourth biggest space power in the EU, and the fifth in terms of its contribution to the European Space Agency (ESA), at EUR250 million.

The Spanish space industry in 2026 is characterised by a number of factors, as follows.

• Strong government impulse: The Spanish public authorities are playing a fundamental role in the development of the space sector through significant investments in RD&I. Prominent examples include programmes such as the Strategic Project for Aerospace Economic Recovery and Transformation (“PERTE”), with EUR4.3 billion invested, and the Space Technology Programme (Programa Tecnológico Espacial or PTE), with EUR70 million invested in 2024. NextGeneration EU funds are also invested to foster innovation in the space sector.
• Strong private sector participation: In Spain, the sector has a number of companies that actively participate in projects of national and international relevance, especially in public-private collaboration, which is a key element for the promotion of the industry. Among these, Airbus Defence and Space España, Indra, HISPASAT, GMV, Hisdesat, Satlantis and PLD Space all stand out, and are all actively involved in national and international projects, collaborating closely with the public sector. These companies are involved in the development of satellites, Earth observation systems and reusable space launchers.
• Public-private partnerships as an engine for development: Synergy between the public and private sectors has been crucial to the success of the space sector in Spain. Programmes such as PAZ, Ingenio and SEOSAT-Ingenio are examples of collaborations that have driven the development of advanced technologies and generated high added-value solutions for society.
• Active collaboration and participation in international and European programmes.
• Most recently, a number of existing projects are being re-analysed in terms of their potential impact on EU and Spanish defence and security. The Ministry of Defence has launched an initiative named “Strategic Modernisation Plans” (Planes Estratégicos de Modernización or PEM) to fund the development and implementation of dual-use technologies.

Another characteristic of the private sector of the Spanish aerospace industry is its specialisation in Earth observation and satellite development segments.

In contrast, Spain lacks autonomy of access to space due to several factors and challenges involved in launch activities (economic, technological, strategic and also regulatory). In particular, the Spanish space sector still lacks a specific legal regime to provide legal certainty to private traffic operators, to gain independence of access to space and to encourage investment by foreign or national private entities. A body of new regulations is expected to be published in the coming years. Meanwhile, companies such as PLD Space (www.pldspace.com) have committed to diversifying the industry despite the economic, technological, strategic and, above all, regulatory challenges of the sector.

The Spanish legal system is based on civil law, which is characterised by its emphasis on written law, codified in systematic legal bodies. The Spanish Constitution (1978) is the supreme rule of the internal legal system and establishes the system of sources of law of the Spanish legal system, in the following order of priority:

• the law, emanating both from the legislative power of the state, and from those provisions of lower rank such as decrees, regulations or ordinances of public law;
• custom; and
• the general principles of law in the absence of law.

Despite the order of precedence established in the constitution, the general principles of law are present at all times, giving the other rules full meaning.

Jurisprudence (repeated pronouncements or judgments in the same interpretative sense of laws or principles of law issued by the Supreme Court and High Courts of Justice) is not a source of law in the Spanish legal system, strictly speaking, as it does not produce positive law. However, it has the function of complementing the legal system, interpreting laws in accordance with the uses, customs and constitutional and general principles of law in order to achieve unity of criteria.

Spain has not yet developed a unified or comprehensive body of regulations on space matters. Pending the approval of a domestic Space Act, the main sources of domestic law specific to space matters are presently limited to:

• Royal Decree 278/1995, which establishes and regulates the registration of objects launched into outer space;
• Law 11/2022 – the General Telecommunications Law;
• Royal Decree 123/2017, which approves the regulation on the use of the public radio-electric domain;
• Law 17/2022, approving the creation of the Spanish Space Agency (Agencia Espacial Española or AEE or “the Agency”); and
• Royal Decree 158/2023, approving the by-laws of the Spanish Space Agency.

However, the configuration of the Spanish legal system allows for the application of more general provisions of the legal system in those matters not specifically regulated by special laws or regulations, as is the case in the following areas:

• civil liability of private operators, to which the provisions of the Civil Code and related laws apply;
• the field of intellectual and industrial property, where the general laws and regulations become relevant;
• the field of public law, in matters of contracts and concessions with the public administrations, where the general regime set out in the 2017 Public Sector Contracts Law and the 2015 Common Administrative Procedure Law applies; and
• the protection of personal data, an important topic for the new space industry, which is regulated by the European General Data Protection Regulation (GDPR) and the 2018 Organic Law.

As stated, works to approve a domestic Space Activities Act are underway, although the results are not expected to be published in the short term due to the recent creation of the AEE. Nevertheless, this is a legislative priority since there is a general consensus that the enactment of a national body of laws and regulations will give private operators greater legal certainty in their economic activities, and that this will lead to greater autonomy in access to space.

The United Nations General Assembly (UNGA) resolutions and Spain’s commitment as a member of international law organisations – the UN, the United Nations Committee on the Peaceful Uses of Outer Space (UN COPUOS) and the International Telecommunication Union (ITU) – on international co-operation, sustainability and the peaceful use of space are reflected in Spain’s space policy, initially through the 2019–2023 Space Strategy and more recently in the 2025 National Aerospace Security. These principles were fully contemplated during the gradual development of a domestic legal framework, as follows.

• Protection of the space environment: Spain has focused much of its public funding on research into and the development of more sustainable technologies, more efficient propulsion systems, recoverable and reusable launchers and space debris mitigation technologies.
• Principle of freedom of exploration and peaceful use of outer space: Spain adheres to the UNGA resolutions on the prevention of an arms race in space and the peaceful use of outer space for exploration.
• International co-operation: Spain participates in numerous international space co-operation programmes, such as those of ESA and NASA (with the Artemis Agreements).
• Non-appropriation of outer space: As a permanent member of COPUOS, Spain supports UNGA Resolution 51/122 of 4 February 1997, the “Declaration on International Cooperation in the Exploration and Use of Outer Space for the Benefit and in the Interest of All States, Taking into Particular Account the Needs of Developing Countries”.

In May 2024, the Socialist Party submitted a proposal to parliament to update and develop the National Space Strategy to raise the current terms to a higher level. This crystallised in the 2025 National Aerospace Security Strategy and in the 2026–2030 Deep Tech Strategy.

Judicial decisions by the Spanish courts on space law remain scarce, although the courts have ruled on issues such as liability for damage caused by space objects and the protection of intellectual property in space.

With the increasing importance of the space industry, Spain intends to maintain its role as an important actor. To achieve this, the public administrations are acting as facilitators of an ecosystem that promotes the technological development of private operators through public funding.

Public-private collaboration is currently the preferred model, along with funds for defence and security projects. To this end, the role of the state will be essential not only in the area of financing, but also in providing a special legal regime for the industry’s activities.

The AEE was created in 2022 and has its headquarters in Seville. It was constituted as a public body, attached to the Ministries of Science and Innovation and Defence, with an extensive range of administrative powers and competencies to meet the objective of centralising inter-ministerial competencies in one single agency.

The most important powers conferred on the AEE include the following:

• Representation before ESA and the European Union Space Programme Agency (EUSPA), specifically by managing the payment and returns derived from the national contribution to the European intergovernmental organisation, as well as managing Spain’s participation in ESA programmes (without prejudice to those attributed to other ministries).
• Promotion of bilateral or multinational co-operation agreements with other space agencies, as well as signing agreements or other legal instruments with public bodies or subjects of international law, or with private entities.
• Co-ordination of defence space programmes and supporting the priorities reflected in the National Security Strategy, the National Aerospace Security Strategy and the National Defence Directive within the framework of the AEE, given the dual character of the Agency and the criticality of space in security and defence aspects.
• Co-ordination, development and direction of plans, strategies and programmes related to research (creation of national space programmes), from both a management and funding point of view.
• Elaboration of a National Space Policy proposal, and design and co-ordination of a National Space Strategy.
• Encouraging the commercial use of space.
• The promotion of public-private partnerships in the space sector, with the AEE being understood not only as a financial partner for private operators but also as a preferred customer for capabilities, products and services.
• The financing and co-ordination of public funds, as well as the creation of economic-financial support lines applicable to programmes of scientific, technological and innovation activities. Previously, the CDTI (an entity attached to the Ministry of Science and Innovation) managed public funds from the EU earmarked for research and scientific activities, but the AEE will now take over this function.
• Support for safety oversight in space or space systems management, in collaboration with the relevant departments for the issuance of certifications, assurances, authorisations, reports or similar instruments, once safety requirements have been verified. It should be noted that the granting of such safety-related licences will apply to launch activities, potential spaceports, sub-orbital flight operations, commercial access to space, space traffic, space debris and satellite constellations.
• Support for security monitoring, in co-ordination with the competent national bodies, against acts of unlawful interference in the field of national security and defence. Such monitoring will be aligned with the requirements set by the EU Security Accreditation Regulations, covering matters such as cyber-attacks, control and management of technology transfers or information protection.
• The most relevant project of the AEE is presently the preparation of a proposal for a Spanish Space Act, in conjunction with the various ministerial departments that make up ESA’s organic composition. The Space Act will create a regulatory framework for space activity in the context of NewSpace.
• Finally, promotion of the private investment ecosystem in the space sector through technology funds, venture capital, investors in emerging companies and support for Spanish companies in the sector by implementing measures to stimulate private investment.

In line with the ministries that make up its Governing Council (the Agency’s collegiate governing body), the AEE is made up of representatives from the Ministries of:

• Science and Innovation;
• Defence;
• Transport, Mobility and Urban Agenda;
• Industry, Trade and Tourism;
• Foreign Affairs, European Union and Co-operation;
• Economic Affairs and Digital Transformation;
• the Presidency, Relations with the Courts and Democratic Memory;
• Finance and Public Function;
• the Interior;
• Agriculture, Fisheries and Food; and
• Ecological Transition and the Demographic Challenge.

However, the management of the spectrum orbit resource and the control and management of the Register of Space Objects fall outside the AEE’s scope; the first is the exclusive responsibility of the Ministry of Economic Affairs and Digital Transformation, while the second is the responsibility of the Ministry of Industry, Trade and Tourism.

Under current laws, there is no specific authorisation regime for space activities. Spain does not yet have a law on space activities that unifies the different types of activities in a single catalogue, nor is there any specific regulation on authorisations and licences. Thus, each project must be analysed on a case-by-case basis to determine which government bodies need to be addressed to obtain the proper approvals.

In any event, registration in the Register of Objects Launched into Outer Space (created by Royal Decree 278/1995) is an obligation for any operator intending to launch any type of satellite or other object into outer space (low or high orbit). This register is attached to the Ministry of Foreign Affairs and mainly serves the purpose of controlling launch activity, in compliance with the international treaties to which Spain is a party – namely, the 1974 Convention on Registration of Objects Launched into Outer Space. The registration of objects allows liability for damage to be attributed to Spain in accordance with international law.

The registration of space objects must contain the following data:

• the name(s) of the launching state(s);
• an appropriate designation of the space object or its registration number;
• the date and territory or place of launch;
• basic orbital parameters, including nodal period, inclination, apogee and perigee; and
• the general function of the spatial object.

The regulations of the Register may be amended in the near future, as some proposals have already been put forward to adapt them to the new economic trends.

The Orbit-Spectrum Resource (OSR) is a public domain asset consisting of bands or bands and frequencies provided by electromagnetic waves located in low-Earth orbit that allow communication via satellite, among other things.

Due to its special relevance in space law, the use and allocation of the OSR is granted in co-ordination with the competent international authority for the management of bands and frequencies for telecommunications, the ITU. In Europe, the European Code of Conduct establishes the basic conditions for communications service providers, and Directive 2014/53/EU of 16 April 2014 harmonises the requirements that member states must meet in order to market radio equipment.

In this regulatory context, Spain has enacted the 2022 General Telecommunications Act (Ley General de Telecomunicaciones or LGT), approving the regulations on the use of the public radio-electric domain and establishing the internal legal regime for the use of radio frequencies by space operators. This Act repeals the previous 2014 Act and has been developed in some detail by Royal Decree 123/2017, which approves the regulations for the use of the public radio-electric domain.

Competent Government Entity in Spain for the Allocation and Supervision of OSRs

The LGT considers that the OSR is owned and administered by the State, as a public domain asset, and determines the Spanish sovereignty of the radio frequency bands when these involve use in the Spanish territory by state institutions or private individuals.

For the management of the national OSR, the LGT created the Operators’ Register, in which any operator intending to operate telecommunications networks must be registered. The requirements for the provision of networks and electronic communications services are regulated in Article 6.2 of the LGT. The Operators’ Register is under the jurisdiction of the National Commission for Markets and Competition (Comisión Nacional de Mercados y Competencia – CNMC).

However, although the CNMC regulates and supervises compliance with the competition rules in the markets, including the regulated telecommunications market, it is not competent to allocate frequencies or grant licences for the use of OSRs. This authority rests with the State Secretariat for Telecommunications and Digital Infrastructures (Secretaría de Estado de Telecomunicaciones e Infraestructuras Digitales – SETID), a government agency attached to the Ministry of Economic Affairs. SETID assigns authorisations for the private use of the OSR to space operators. The granting of authorisation is conditional upon the following, among other requirements:

• providing a guarantee of EUR200,000;
• prior ITU authorisation for the use of the band requested; and
• proof of the financial solvency, technical ability and feasibility of the applicant’s project.

SETID has six weeks from the date on which the ITU reserves the requested OSR in favour of the Kingdom of Spain to decide on an application for the granting of licences. Should this period elapse without an express decision having been notified, the application for granting the licence will be deemed to have been rejected.

It should be added that, in the event that the radiocommunications infrastructure includes a subordinate terrestrial network, the frequencies of this terrestrial network (other than the frequencies of space services) will not be included in the previous licence for the private use of the OSR, and it will be necessary to obtain another licence for their use in the “Terrestrial Segment”, regulated by the LGT.

Management and Co-Ordination of Radio Spectrum Frequencies and Slots

SETID works closely with international (ITU), intergovernmental (ESA) and national (CNMC) bodies to ensure compliance with international agreements and regulations on frequency and orbital slot allocation. To this end, SETID develops National Frequency Plans in which it allocates specific frequency bands for different telecommunication services (mobile, radio, television, emergency services) according to the needs identified, in which the technical and operational conditions for the use of each frequency band are defined, including the maximum powers, and it sets technical standards to be met by the equipment and systems that use these allocated frequencies (or for which their allocation is foreseen).

SETID is also responsible for controlling the use of the assigned spectrum by means of technologically advanced monitoring systems that detect non-compliance with the assigned technical standards and conditions of use. This allows the detection of possible interferences. Non-compliance by operators with the technical standards and licence conditions that generate harmful interference leads to the application of the sanctioning regime provided for in the LGT (fines, suspension of licences, confiscation of the equipment causing the interference, and the issuing of corrective orders to prevent future infringements).

The CNMC supervises compliance with regulations in the telecommunications market from a free competition perspective. Its authorities include a sanctioning regime applicable to breaches or conduct that significantly affects competition or efficient use of the spectrum, and to anti-competitive practices or abuses of dominance in the sector. The seriousness of the non-compliance determines the application of sanctions (fines, cessation of activity of the offenders, and publication of the sanctions).

Consultation and Conflict Resolution Mechanisms in Case of Interference

The LGT provides for a public consultation procedure on spectrum planning and assignment with the participation of relevant stakeholders, including telecommunications operators, government agencies and the general public. In relation to this mechanism, SETID announces the launch of a public consultation through its website and other communication channels, with detailed reference to studies, impact analysis of the plans and any other relevant information. Subsequently, SETID analyses the contributions of the participants and evaluates the comments received, concluding in a final report that is publicly accessible.

The LGT establishes SETID’s mediation and arbitration procedures in the resolution of interference disputes:

• SETID and the CNMC can act as mediators in disputes between operators, and between operators and end-users; and
• the parties can also call upon a neutral arbitrator appointed by SETID or an independent telecommunications expert, whose decision will be binding.

Finally, the LGT provides for a complaints procedure before the CNMC and SETID, respectively, in which operators and users must detail the nature of the interference and provide evidence. The CNMC or SETID, as appropriate, may initiate an investigation through technical inspections to assess the validity of the complaint. If the interference is confirmed, corrective measures are applied, which may include technical adjustments, fines or modifications to frequency allocation, and even orders forcing the responsible party to cease the activity causing the interference.

Management of Orbital Slots

Through Royal Decree 517/2024, the public enterprise ENAIRE was appointed as the sole service provider for Spanish U-Space areas. An Interministerial Commission is responsible for designating particular geographical zones such as U-Space, and the Spanish Aviation and Safety Agency (Agencia Estatal de Seguridad Aérea – AESA) is in charge of certifying and supervising U-Space service providers.

The Spanish state acts mainly as a facilitator and user in the launch process. For the time being, Spain has no independent space access capability, so its role in launching objects into outer space depends on the services provided by international partners, mainly ESA, whose spaceport is located in Kourou (French Guiana).

Spain’s launch capacity is lacking for the following reasons:

• the high cost of launch activity;
• a national policy to promote the development of activity and participation by private operators has been initiated only very recently;
• Spain has always operated under the umbrella of ESA, participating in many of its space programmes; and
• the lack of development of a national space legal framework has slowed down the development of the space industry, generating legal uncertainty in the traffic of private operations and making private investment unattractive.

A recent example of this dependence on launch capability, including at a European level, has been the need for ESA and Europe to contract the US launch service provider “SpaceX” for the launch of four Galileo satellites into space from US territory. This operation had to be carried out through a private contract with SpaceX and a bilateral EU-US agreement to establish procedures for the security of EU classified information during the satellite launch campaigns.

In early October 2023, Spain demonstrated its ability to design and produce an entirely Spanish rocket and launch it from national territory. This milestone was made possible by the public-private partnership between the company PLD Space and the public authorities. MIURA-1 was launched from the Arenosillo spaceport (Huelva) and performed a suborbital flight.

The second phase of the rocket’s reintegration (it was to be reusable) could not be carried out successfully, but this did not prevent the mission from being classified as a Spanish and European milestone. MIURA-5 is currently under construction and the first test flight is foreseen for the second half of 2026.

Corpus Iuris Spatialis and Spain

International space law or Corpus Iuris Spatialis is historically based on the following five United Nations treaties, which establish fundamental principles such as freedom of exploration and peaceful use of space, non-appropriation and responsibility for space activities:

• the 1967 Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies (the “Outer Space Treaty” or OST);
• the 1968 Agreement on the Rescue of Astronauts, the Return of Astronauts and the Return of Objects Launched into Outer Space;
• the 1972 Convention on International Liability for Damage Caused by Space Objects;
• the 1974 Convention on Registration of Objects Launched into Outer Space; and
• the 1979 Agreement Governing the Activities of States on the Moon and Other Celestial Bodies.

Spain is a state party and has ratified all these treaties, except the 1979 Moon Treaty.

Other Relevant International Treaties

Spain has also ratified the following relevant international conventions:

• the 1963 Treaty Banning Nuclear Weapon Tests;
• the 1971 Agreement relating to the International Telecommunications Satellite Organization;
• the 1974 Convention Relating to the Distribution of Programme-Carrying Signals Transmitted by Satellite (signature only);
• the 1975 Convention for the Establishment of a European Space Agency (ESA);
• the 1976 Convention on the International Mobile Satellite Organization;
• the 1982 Convention Establishing the European Telecommunications Satellite Organization (EUTELSAT IGO);
• the 1983 Convention for the Establishment of a European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT); and
• the 1992 International Telecommunication Constitution and Convention.

The following instruments are also of importance.

• The Artemis Agreements were established in 2020 by the US Space Agency (NASA) and reinforce the commitment of signatory states (including Spain) to the norms of international space law, establishing a set of practical principles to guide co-operation in space exploration among nations, including those participating in NASA’s Artemis Programme. Spain became a direct signatory to the Artemis Agreements through the AEE.
• International Satellite Search and Rescue System (COSPAS-SARSAT): Spain is a participating state in the ground segment of the international distress alert system that uses satellites to locate and rescue people in distress on land, at sea or in the air.

Other International Instruments

The resolutions of UNGA and the guidelines of the UN-COPUOS are also part of the Spanish legal environment. Although UNGA resolutions do not have binding effects in the strict sense of treaties, they do form part of international custom (“soft law”) recognised by state practice. The most relevant UNGA resolutions in the field of space include the following:

• UNGA Resolution 41/61 on “Principles Relating to Remote Sensing of the Earth from Outer Space”;
• UNGA Resolution 47/68 on “Principles Relevant to the Use of Nuclear Power Sources in Outer Space”;
• UNGA Resolutions 51/122 and 75/36 (of 2023, most recently): “Declaration on International Co-operation in the Exploration and Use of Outer Space for the Benefit and in the Interest of All States, Taking into Particular Account the Needs of Developing Countries”; and
• UNGA Resolutions 78/19 and 78/19 (2023) on “Prevention of an arms race in outer space”.

Sustainability

In the area of sustainability, an area of growing concern, the Inter-Agency Space Debris Coordination Committee (IADC) and the United Nations Office for Outer Space Affairs (UNOOSA) established their “Space Debris Mitigation Guidelines”, which the UNGA endorsed in its Resolution 62/217 for private operators, setting out “good practices” for the long-term sustainability of space activities. However, the latest UNGA Resolution (A/RES/778/72) about guidelines on long-term sustainability and space debris mitigation states that they are still under constant development and adapting to the new capabilities of the sector in practice, in co-operation with COPUOS and the IADC.

European Legal Framework

Spain is a member of the EU, and of the ESA. As such, a number of European rules and regulations on space matters form part of the Spanish legal system, with the most relevant being as follows:

• the Founding Convention of the European Space Agency of 30 May 1975 – Spain ratified the Convention on 15 January 1979 and participates actively in its programmes;
• Directive 2007/2/EC establishing an Infrastructure for Spatial Information in the European Community (“INSPIRE”);
• Regulation (EU) 2021/696 of the European Parliament and of the Council of 28 April 2021 establishing the Union Space Programme and the European Union Agency for the Space Programme;
• the Charter of EUSPA, which establishes the legal and operational framework for EUSPA – Spain participates in EUSPA, which manages the European satellite navigation (Galileo and EGNOS) and Earth observation (Copernicus) programmes; and
• Regulation (EU) 2024/795 of the European Parliament and of the Council of 17 May 2024 establishing a Strategic Technology Platform for Europe (“STEP”).

Work towards the approval of a common EU regulation to govern certain aspects of space activities, known as the EU Space Act, was ongoing at the time of publication of this guide.

COPUOS and the Conference on Disarmament

Spain has been a permanent member of COPUOS since 1994 and actively participates in the Conference on Disarmament.

In COPUOS, Spain plays a leading role in promoting the peaceful and sustainable use of space. It has actively participated in the development and adoption of space debris mitigation guidelines that seek to reduce the creation of new debris and manage existing debris to minimise the risk of collisions. Within COPUOS, Spain supports initiatives that promote international co-operation in space exploration.

Spain actively participates in the UN Group of Governmental Experts on Transparency and Confidence-Building Measures in Space Activities; these measures include the disclosure of information on space launches and the promotion of transparent practices among nations. It should be stressed that Spain has implemented a Registry of Space Objects that complies with the 1974 Convention on Registration of Objects Launched into Outer Space, ensuring that all satellites and objects launched by Spain are properly registered and notified.

In the Conference on Disarmament, Spain normally takes a stand against the militarisation of space and supports the prohibition of weapons of mass destruction in outer space, promoting the adoption of international treaties and agreements to strengthen space security and prevent an arms race in space.

Spain actively participates in groups of government experts that study and propose measures for the prevention of an arms race in space. It contributes with research and proposals based on international law and best practices.

Incorporation of International Instruments in the Spanish Legal System

Spain has a historic track record of compliance with the international treaties to which it is a party. Furthermore, from the moment they come into force, international treaties are higher on the hierarchy of the Spanish legal system than domestic laws and regulations, which must be interpreted and applied in accordance with such international instruments. Spanish courts and authorities also regularly apply the provisions of international treaties.

Liability Rules

The Treaty on International Liability for Damage Caused by Space Objects has been directly applicable in Spain since its ratification in 1980. Articles VI and VII of the Treaty attribute the liability for damage caused to third parties by space objects either to the states themselves, or jointly and severally to the states and their private operators.

Civil liability for damages on the part of states consists of the action for recovery by states against private entities within their own jurisdiction. In this matter, the Spanish legal system lacks a specific civil liability regime for space activities. However, the usual practice is based on practices developed at the international level, customs and procedures, and certain provisions of the 1980 Insurance Contracts Act.

The future Spanish Space Act is expected to provide some detailed provisions on this matter.

Application of the “Due Regard” Principle

Article IX of the OST provides for the duty of due regard for state parties during their conduct of space activities, according to which, the corresponding interests of all other state parties must be considered, and appropriate measures for avoiding harmful interference must be taken.

Space Insurance in Spain and Insurance Requirements for Space Operators

Spanish legislation does not yet specifically regulate or establish the mandatory requirement of insuring a space object prior to its launch and once it has been placed in orbit by its owners. However, the high participation of the private sector in space activities means that the same practice defines an international framework of customs and practices in the field of space insurance. An alternative, often used in practice, is that the operator of the space object adheres to the insurance policy of the provider of the launching service.

Risk Assessment and Determination of Insurance Premiums

In Spain, the lack of a national space law causes legal uncertainty for insurers who, not being sufficiently familiar with this new industry and its practices, are hesitant to develop the necessary insurance products. Until a proper regulatory framework is in place, insurers will continue to assess the risks and determine insurance premiums in accordance with general market practice throughout the world (ie, using the “Probable Maximum Loss” method originated in the USA or the “Modelled Insurance Requirement” of the UK space regulation).

Under ESA’s public-private contracting system with private operators, such operators can benefit from the agreement between ESA and its insurance companies in the framework of collaboration in European space programmes.

There is no express regulation or legal provision in force in Spain governing the problem of activities in the very high altitude (VHA) sphere. As in many other countries, the issue is debated at an academic level and, to achieve harmonisation, will likely have to be regulated through international treaties or, at least, at the European Union level.

Subject to the provisions of international conventions to which Spain is a party, and due to the lack of a specific space regulation, activities to be carried out in space (healthcare, life sciences, agri-food, data processing, etc) are currently subject to and governed by the same rules and regulations as if such activities were to be carried out on Earth.

No specific regulations relating to non-interference with other spacecraft, space missions or space-faring entities have yet been approved. Therefore, these issues would have to be analysed and solved in accordance with the applicable international conventions and international customary law.

Obligations of Operators in Outer Space and in Launch and Re-entry Activities on Earth

Since Spain has not developed a specific law on space, the behaviour of operators in space is based on the obligations derived from international treaties and customary law, as well as the general obligations applicable to Spanish enterprises.

ESG Guidelines for Space Activities

In the field of space debris mitigation, operators under Spanish jurisdiction should follow the COPUOS Space Debris Mitigation Guidelines and ESA’s European Code of Conduct on Space Debris Mitigation, which, among other issues, oblige launch service operators and developers to plan the re-entry of their space objects in a safe manner and to implement follow-up and subsequent recovery measures if such objects must remain in orbit. These guidelines are not an obligation for private operators in Spain; they are recommendations issued by international or intergovernmental organisations of which Spain is a member.

In its present drafting, the future EU Space Act expressly contemplates that operators of space activities must include debris reduction and recovery criteria and measures right from the outset of their projects.

Specific Intellectual Property Rules Applicable to Space Activities and Assets

In Spain, intellectual property protection is regulated by the Intellectual Property Act, approved by Royal Legislative Decree 1/1996. Industrial property is regulated by the Patent Act (Law 24/2015), the Trademark Act (Law 17/2001) and the Law on the Legal Protection of Industrial Design (Law 20/2003), together with their respective regulations.

None of these laws provide for their specific application in outer space or to outer space activities. At the European level, there is also no unitary regulation for the protection of industrial property in outer space, although there are Community regulations applicable in the European territorial scope, such as Regulations (EU) 1257/2012, on protection by means of unitary patents, and 2015/2424, on the European trade mark.

On the other hand, there is a regime of jurisdictional distribution over inventions under development on the International Space Station (ISS). Article 21 of the Intergovernmental Agreement on the International Space Station provides that any invention activity on the ISS is deemed to take place in the territory of the partner state where the flight element is registered. Thus, the applicable jurisdiction is the state of registration, although the inventor may apply for a patent in several countries.

At the present time, the data protection aspects of space activities are governed by the general provisions of the GDPR and the 2018 Organic Law on Data Protection, as no specific regulations have been passed for the space industry. These issues, including the international transfer of data, must therefore be analysed in the light of existing legislation. However, the geopolitical environment seems to show a trend towards stricter controls and requests from government agencies for certain types of data, based on the argument of national defence and security. This trend is likely to be subject to scrutiny in the courts in the future if it is perceived that essential data protection principles are endangered.

There is no national legislation in Spain for space data spaces.

The main legal provision to be considered is Royal Decree 311/2022, which approves the National Security Strategy (Estrategia Nacional de Seguridad or ENS). This legal provision incorporates many of the NIS-2 regulations and is mandatory for most actors in the space industry.

The duty to protect sustainable access to space is enshrined in Article IX of the Space Treaty. However, the international community has only recently shown concern for the mitigation of space rights, and the current regulatory framework is outdated and insufficient for today’s reality of space debris.

In this regard, international organisations such as COPUOS and ESA have promulgated their own Space Debris Mitigation Guidelines (see 2.7 Commitment to International Treaties and Multilateral Discussions). As a member state of the EU, a founding state of ESA and a member of COPUOS, Spain has adopted all the guidelines and recommendations that constitute customary law.

Currently, there are no specific regulations in Spain or the EU on critical space minerals.

At the 2023 Seville Space Summit, the Zero Debris Charter was published and opened, which is aligned with the space sustainability goals for 2030. At the same summit, the “Space for a Green Future” initiative was also presented, with the intention of reducing CO₂ in large cities and favouring sustainable mobility.

In November 2023, the Council of Ministers in Spain approved an agreement increasing the budget line for space debris monitoring expenditure through the AEE by EUR4 million.

In this way, Spain aims to comply with the Code of Conduct on Space Sustainability, fulfilling four particularly important practices contained therein:

• mitigating the risk of collision in orbit;
• minimising the threat of non-transportable debris;
• preserving human life in space; and
• limiting the impact on optical astronomy.

Finally, from an EU point of view, space debris mitigation is sought through Space Traffic Management by the Global Satellite and Operators Association, defined as “the means and standards for accessing, operating in and returning from outer space in a safe, sustainable and secure manner”.

Furthermore, in February 2022, a proposal for a regulation on secure space connectivity from the EU was presented, resulting in the “Conclusions of the EU Competitiveness Council on Space Traffic Management”.

See 5.2 Climate Change and Space Activities. It is anticipated that Spain will align with EU principles and regulations on space debris.

Spain does not yet have a special tax regime for space activities. Therefore, the general provisions of the 2014 Corporate Income Tax Act, the 1992 Value Added Tax Act, etc, are relevant.

Spanish provisions on corporate income tax establish certain tax deductions for research, development and technological innovation activities, subject to a binding assessment by the State Tax Authority (Agencia Estatal de Administración Tributaria or AEAT). Operators must apply to the AEAT for a prior assessment of R&D expenses before they are incurred. These deductions vary between 25% and 42% of the R&D expenditure. Tax deductions are also available for technological innovation – ie, funds invested in the materialisation of new products, schemes and designs, the creation of non-marketable prototypes and pilot projects.

These regulations provide a favourable fiscal framework that encourages the development of advanced technology and space projects in Spain, thus supporting growth and innovation in the aerospace sector.

Given the international nature of most space assets and players, the tax implications relating to the transfer or sale of space assets need to be analysed on a case-by-case basis. In general terms, VAT exemptions may be applicable, although this needs to be verified in accordance with the specific transaction structure.

The space industry in Spain is growing, driven by innovative start-ups and supportive government policies. There is increasing interest from investment funds and financiers, which see opportunities in the space sector. The evolution in fundraising is positive, with an increase in investments and the creation of specialised incubators and accelerators. Initiatives such as the ESA Business Incubation Centre (BIC) programme in Spain facilitate access to funding and technical support, promoting a dynamic and attractive ecosystem for new space companies.

Venture capital funds in Spain currently investing in space activities include:

• K Fund;
• Samaipata Ventures;
• Adara Ventures;
• Bullnet Capital;
• Inveready; and
• Caixa Capital Risc.

The main source of funding for space activities in Spain still comes from public funds, especially subsidies.

On 15 May 2024, the Ministry of Science, Innovation and Universities (Ministerio de Ciencia, Innovación y Universidades or MICIU) published the 2024 call for the Space Technology Programme (Programa de Tecnología Espacial or PTE), managed by the CDTI with the collaboration of the AEE. Endowed with EUR70 million from the PERTE, the call will finance – with up to EUR30 million – projects for the development of space products and processes, as well as technologies with high disruptive potential. The remaining EUR40 million will be earmarked for advanced projects that boost the maturity level of space technologies; of this budget, EUR16 million is earmarked for small projects.

Funding can also be obtained through certain defence-related programmes such as the PEM’s mentioned in 2.1 Characteristics of the Space Industry.

Secondly, the funding channels of private companies in the framework of space projects with ESA and other public-private partnerships between government and private companies also account for a high percentage of funding in the Spanish space industry.

Financing through venture capital firms, crowdfunding and private investment rounds is also on the rise. For example, PLD Space, which began as a start-up, has raised EUR78 million from private investors and EUR42 million from the PERTE programme.

The main fundraising initiative in Spain is the creation of specialised incubators and accelerators, such as ESA BIC in Spain, located specifically in the cities of Barcelona and Madrid. Since the seat of the AEE is in Seville, similar initiatives can be expected to take place there. In addition, the tax incentives discussed in 6.2 Tax Incentives for Space Investors and the support from the central and regional governments through proactive policies are intended to encourage industry growth and investment in space technology.

Two main aspects should be considered when it comes to foreign investments in Spain.

• Foreign investment regulations: In line with European regulations, the 2023 Foreign Investments Act contemplates certain restrictions on foreign investments in Spanish critical technologies or infrastructure (including space technologies and infrastructures) due to national security concerns. This type of investment requires prior government approval.
• Export controls on dual-use products and technologies: Similarly, the export of products and technologies that are classified as dual-use products is subject to strict export controls and, under certain circumstances, international sanctions. Space assets and technology certainly fall under this category, so the relevant regulations need to be taken into account.

Documentation processes for NewSpace fundraising do not substantially deviate from those for fundraising projects in technological enterprises not linked to space. From experience, the concerns and needs of the parties (whether investor or target) are very similar to those of technological enterprises generally.

There does not appear to be much difference in funding projects for space companies compared to other technological enterprises. Usually, the due diligence will take into account aspects such as the protection of the intellectual property, compliance with regulatory issues, dual-use questions, existence of public subsidies, etc – although this needs to be analysed in each specific case.

Given the rather limited size of the Spanish financing market and the limited availability of private funding in comparison to other jurisdictions, parties often define their liquidity events with reference to foreign markets, particularly in connection with listings on foreign securities markets.

Unlike in other countries, the Spanish securities markets are not a huge source of financing, except for a limited number of companies. Stock exchanges from other countries (the USA, the UK, the Netherlands, etc) play a larger role in this respect.

Spain is party to international treaties on the protection of intellectual and industrial property rights and has a robust body of legislation in this area. Courts regularly enforce intellectual property rights, although no specific rules relating to space projects have been published. Given the specific nature of this type of project, a detailed analysis would have to be made in each case to assess whether it could be protected via patents, or whether other mechanisms should be used.

Established industry players such as Indra or GTD are familiar with the protection of their intellectual property assets and have, generally speaking, strong strategies in this respect. The challenge lies with start-ups and smaller enterprises, which often lack the knowledge and the financial means to protect their creations. The public administrations regularly offer training and information on this topic to foster such protection. This is particularly relevant in joint co-operation projects between universities or higher education institutions and private enterprises, where a specific set of regulations aims to ensure that the knowledge developed at the university level remains at least co-owned by the institution. In this connection, universities often use a standard form of contract which interested parties must adhere to.

There do not appear to have been any discussions in Spain regarding the application of patent law for devices and activity manufactured or performed in space. Given Spain’s membership of the EU, such issues should be decided at the Community level.

The Madrid-based arbitration body CIAM-CIAR launched a working group in early 2026 to foster the inclusion of arbitration clauses in agreements and disputes involving the aviation industry. At the time of publication of this guide, the group was mapping relevant areas where such inclusion would make the most sense.

At the time of publication of this guide, no claims appear to have been lodged in Spain by foreign investors opposing the State in space-related arbitration matters.

At the time of publication of this guide, there does not appear to have been any space-related litigation in Spain.
