Alternative Agreements: The Artemis Accords, introduced by NASA and the U.S. in 2020, aim to provide a framework for lunar exploration that aligns more with current spacefaring nations' practices, focusing on cooperation but not necessarily endorsing the Moon Treaty's specific principles.
Future Lunar Activities: As interest in lunar exploration grows, the principles of the Moon Treaty might be revisited or reinterpreted to address issues like lunar mining, habitat construction, and resource sharing.
Moral and Ethical Guidance: Even if not legally binding for all space nations, it sets a moral and ethical framework for how lunar activities should ideally proceed.

Conclusion:

The Moon Treaty stands as an ambitious attempt to regulate lunar activities for the benefit of all humanity. However, its limited adoption has significantly curtailed its practical impact. Its principles continue to be part of the broader conversation about space law, ethics, and international cooperation in space exploration. As new lunar missions are planned, the treaty's ideals might inspire or challenge policymakers, scientists, and legislators to rethink how we manage and utilize celestial bodies.

Artemis Accords:

The Artemis Accords are a set of bilateral agreements between the United States and other countries, aimed at establishing a common set of principles, guidelines, and best practices for cooperative space exploration, particularly in the context of NASA's Artemis program for lunar exploration. Here's an in-depth look at the Artemis Accords:

Purpose and Background:

Initiated: By the United States in 2020 as part of the broader Artemis program, which seeks to return humans to the Moon by 2026, establish a sustainable lunar presence, and eventually enable human missions to Mars.
Foundation: Grounded in the 1967 Outer Space Treaty, the Accords aim to expand and clarify principles for space exploration in a modern context.

Key Principles:

Peaceful Exploration: Activities must be for peaceful purposes, consistent with international law, including the Outer Space Treaty.

Asteroid Mining:

Asteroid mining refers to the extraction of valuable resources from asteroids and other minor planets. This concept, once the domain of science fiction, is now being seriously considered as a potential industry, leveraging advancements in space technology. Here's an in-depth look at asteroid mining:

Motivation and Benefits:

Resource Scarcity: Earth's resources are finite, and certain minerals, like platinum group metals (PGM), are becoming scarce or geopolitically sensitive.
Economic Potential: Some asteroids are believed to contain vast quantities of metals like iron, nickel, gold, and PGMs, potentially worth trillions or even quadrillions of dollars.
Space Infrastructure: Mining asteroids could supply materials for space habitats, solar power satellites, or fuel for spacecraft, reducing reliance on Earth's launch capabilities.
Environmental Impact: Extracting resources in space could lessen the environmental toll of mining on Earth.

Challenges:

Technological: Developing the technology to reach, land on, extract materials from, and process them in space is complex.
Economic Viability: The high costs of space missions must be balanced against the return on investment, which is uncertain due to market fluctuations and the speculative nature of asteroid composition.
Legal Framework: The legal status of mining rights in space is not fully established, though steps like the U.S. Commercial Space Launch Competitiveness Act of 2015 provide some clarity.
Operational: Managing operations in microgravity, protecting human and robotic workers from radiation, and dealing with the harsh space environment.
Transportation: Returning mined materials to Earth is expensive and could disrupt markets if done in large quantities.

Key Players and Developments:

Private Companies:
Planetary Resources (now part of ConsenSys) and Deep Space Industries (merged with Bradford Space) were early pioneers, though both faced financial challenges.
AstroForge: Aiming to refine metals in space and return valuable minerals to Earth.
Trans Astronautica Corporation (TransAstra): Developing technologies for asteroid capture and utilization.
Government and Space Agencies:
NASA: Missions like OSIRIS-REx and the upcoming Psyche mission are studying asteroid composition, which indirectly supports mining prospects.
ESA (European Space Agency) and JAXA (Japan Aerospace Exploration Agency) have conducted sample return missions from asteroids.
Technological Advances:
Robotics: Autonomous robots are essential for mining operations in space.
In-Situ Resource Utilization (ISRU): Techniques for using asteroid materials directly in space.
Propulsion: Advances in propulsion like ion drives or solar sails might reduce travel time and costs.

M-type Asteroids: Rich in metals like iron, nickel, and platinum.
C-type Asteroids: Potentially rich in water and volatiles, useful for fuel or life support.

Current Status and Future Outlook:

Research and Development: Much of the current work is in understanding asteroid composition, developing technologies, and proving concepts in space.
Commercial Missions: Companies are moving towards testing technologies in space, with some planning first mining missions in the near future.
Legal and Ethical Considerations: Discussions are ongoing about property rights, environmental impact on space environments, and equitable benefit sharing.
Public Perception: There's a mix of excitement and skepticism regarding the feasibility and ethics of asteroid mining.
Long-Term Vision: Beyond immediate financial gain, asteroid mining could play a crucial role in space colonization, providing materials for space habitats, and supporting long-term human presence in space.

Asteroid mining stands at the intersection of technology, economics, and law, with the potential to reshape our approach to resources, both on Earth and in space. While still in its infancy, the field is progressively moving from theoretical discussions to practical implementation, with significant implications for the future of space exploration and human expansion into the cosmos.

Space Debris Removal:

Space debris, or space junk, includes defunct satellites, spent rocket stages, and fragments from collisions or explosions, orbiting Earth at high speeds. This clutter poses significant risks to operational spacecraft, including satellites and the International Space Station (ISS). The following details the latest developments, methods, and initiatives in space debris removal:

Current Situation:

Quantity: There are millions of pieces of debris, with the U.S. Space Surveillance Network tracking over 27,000 objects larger than 10 cm. Smaller debris, while less visible, still poses a threat.
Risks: Debris travels at speeds up to 17,500 mph (28,000 km/h), making even small pieces potentially catastrophic upon impact.

Methods of Removal:

Active Debris Removal (ADR):

Capture and Deorbit: Using robotic arms, nets, harpoons, or magnetic systems to grab debris and either deorbit it to burn up in the atmosphere or move it to a "graveyard" orbit.

Examples:
RemoveDEBRIS: A project demonstrating net and harpoon capture methods.
ELSA-d: By Astroscale, using magnetic capture technology.

Passive Removal:
Drag Augmentation: Deploying devices like drag sails or balloons to increase atmospheric drag on debris, accelerating its decay and re-entry.
Laser Ablation:
Using ground-based or space-based lasers to slightly slow down debris, altering its orbit so it eventually re-enters the atmosphere.
Tethers:
Electrodynamic or momentum exchange tethers to either drag debris down or change its orbit.
Ion Beam Shepherds:
Using an ion beam to push debris into a lower orbit where it will naturally decay.

Latest Developments:

ISRO's Efforts: The Indian Space Research Organisation (ISRO) has demonstrated its Debris Capture Robotic Manipulator (DCRM) on the PSLV Orbital Experiment Module (POEM-4), showcasing tethered debris capture.

ESA's Initiatives: The European Space Agency (ESA) is actively working on debris removal with missions like ClearSpace-1, set to remove an ESA-owned piece of debris in 2025, and has been developing technologies under the Clean Space initiative.

Commercial Ventures:
Astroscale: A leader in commercial debris removal, with missions like ELSA-d for demonstration and ELSA-M for commercial operations.

ClearSpace: Working with ESA for the first commercial debris removal mission.

Space Force's Orbital Prime: The U.S. Space Force initiative to encourage private sector solutions for debris removal.

Technological Advances: Research into new materials, propulsion systems, and AI to make debris removal more efficient and cost-effective.

Challenges:

Cost: The expense of missions specifically for debris removal is high, and there's debate over who should bear these costs.
Legal and Ethical Issues: Determining who is responsible for debris, the legality of removing others' debris, and ensuring equitable practices.
Technical Challenges: Capturing tumbling or uncooperative objects in space, managing the energy required, and ensuring no new debris is created during removal.
Political and International Cooperation: Space debris does not respect national boundaries, necessitating global cooperation which can be complex due to geopolitical tensions.

Future Directions:

Regulation: More stringent international agreements on debris mitigation and removal, potentially through updates to the Outer Space Treaty or new accords.
Innovation: Continued development in robotics, AI, and materials science to improve the efficiency and safety of debris removal operations.
Sustainability: Moving towards a "Zero Debris" approach where each launch includes plans for the spacecraft's end-of-life management.
Public and Private Partnership: Increasing collaboration between government agencies, private companies, and international bodies to fund and execute debris removal.
Education and Awareness: Raising awareness about the importance of space cleanliness to foster support for debris removal initiatives.

Space debris removal is a crucial aspect of ensuring the sustainability of space activities. As the number of satellites and space missions increases, so does the urgency to find effective, scalable solutions to keep our orbital highways clear.

Space Law and Debris:

Space law, which governs activities in outer space, has significant implications for managing space debris. Here's an analysis of how space law intersects with the issue of space debris:

Legal Framework:

Outer Space Treaty (1967):

Key Provisions:
Article IX mandates that states must conduct activities in outer space with "due regard to the corresponding interests of all other States Parties to the Treaty," which can be interpreted to include debris mitigation and removal.
However, it doesn't explicitly address debris, focusing more on preventing the "harmful contamination" of space, which traditionally has been linked to biological contamination.

Liability Convention (1972):
Liability for Damage: States are liable for damage caused by their space objects, including debris, to other states' space objects or on Earth. This convention provides a legal basis for compensation claims related to debris incidents.
Registration Convention (1976):
Registration: Requires states to register space objects they launch, which helps in identifying the responsible party for debris.
Rescue Agreement (1968):
Return of Objects: States are obliged to return any foreign space objects they recover, which might include debris.

Guidelines and Non-binding Agreements:

UN Space Debris Mitigation Guidelines (2007): These voluntary guidelines encourage space-faring nations to minimize debris creation through design, operations, and disposal practices.
IADC (Inter-Agency Space Debris Coordination Committee) Guidelines: Aimed at preventing the creation of new debris and managing existing debris, these guidelines have influenced national policies but are not legally binding.
Artemis Accords (2020): While primarily focused on lunar exploration, they include commitments to manage debris responsibly, advocating for the establishment of "safety zones" to prevent interference from debris.

Legal and Ethical Challenges:

Jurisdiction and Ownership: Space debris remains under the jurisdiction of the state of registry, even if it's no longer functional. This raises questions about who can legally remove or alter its orbit.
Consent for Removal: There's legal ambiguity around whether debris can be removed without the consent of the launching state, especially since space objects are not considered abandoned under current law.
Liability for Removal: If an entity attempts to remove debris and causes further damage or creates more debris, questions arise about liability.
International Cooperation: Effective debris management requires cooperation, but there's no enforceable international treaty specifically for debris removal.
Environmental Concerns: The concept of space as a common heritage of mankind raises questions about the environmental impact of debris on the space environment.

Recent Developments and Proposals:

FCC Space Debris Rules: The U.S. Federal Communications Commission has introduced rules requiring satellite operators to deorbit their satellites within 5 years after mission completion, setting a precedent for regulatory action.
ESA's Zero Debris Charter: Aims for a zero debris approach by 2030, encouraging missions to be designed with debris mitigation in mind from the start.
National Regulations: Countries like Japan and the UK are integrating debris mitigation into their national space laws, setting standards for satellite disposal.
Legal Scholarship: There's growing academic interest in developing new legal frameworks or interpreting existing laws to better address debris, including concepts like "space salvage" or updating the Liability Convention.

Future Directions:

Treaty Updates: There might be a push to update or create new international treaties that specifically address space debris.
Customary International Law: As states and private entities increasingly take action on debris, new norms might emerge through practice.
Insurance and Financial Mechanisms: Developing insurance products or financial incentives for debris mitigation and removal.
Educating and Engaging Stakeholders: Raising awareness among space actors about legal responsibilities and encouraging compliance with guidelines.
Technology and Policy Synergy: Ensuring that legal frameworks evolve in tandem with technological capabilities for debris management.

Space law and debris management are at a critical juncture, where the legal community, policymakers, and space agencies are working to adapt existing laws or propose new ones to ensure the sustainability of space activities. The challenge is to balance the rights of nations and companies with the collective interest in preserving the space environment.

Space Salvage Laws:

The concept of space salvage laws is somewhat speculative since there isn't a comprehensive, universally accepted legal framework for salvaging objects in space. However, here's an exploration based on current international space law, maritime law analogies, and ongoing discussions:

Current Legal Context:

Outer Space Treaty (1967):
Article VIII: States that objects launched into space remain under the jurisdiction and control of the state that launched them. This suggests that space objects, even when they become debris, are not considered abandoned and retain their ownership.
Liability Convention (1972):
This convention deals with the liability for damage caused by space objects, but it doesn't address the salvage of those objects explicitly.
Registration Convention (1976):
Requires the registration of space objects, which helps identify the state responsible for an object, thereby complicating the idea of salvage without permission.

Maritime Salvage Law Analogies:

Maritime Law: Salvage in maritime contexts often allows for rewards to those who save ships or their cargo in distress, but this is based on the principles of no cure, no pay, and the vessel being in peril.
Application to Space: The maritime principle of salvage is not directly applicable because space objects are not considered abandoned, and the environment is vastly different. The concept of "peril" in space might be interpreted differently, e.g., as an object posing a collision risk or becoming uncontrollable.

Challenges and Considerations:

Ownership and Consent: Unlike maritime salvage where abandonment can be clearer, space objects remain under their original jurisdiction, requiring consent for any salvage operation.
Economic Incentives: There's currently no clear legal or economic incentive structure for salvaging space debris, unlike the potential rewards in maritime law.
Liability: If an entity attempts to salvage space objects and causes further harm or creates more debris, questions of liability arise under the Liability Convention.
International Cooperation: Salvaging space debris often requires international cooperation due to the multitude of nations and private entities involved in space activities.
Technological Feasibility: The technology for capturing, controlling, and safely disposing of or reusing space debris is still developing.

Emerging Concepts and Proposals:

Space Salvage as a Service: Some propose that private companies could be incentivized to undertake debris removal, perhaps through government contracts or by gaining rights to materials or technology from defunct satellites.
Legal Precedents: There are discussions on whether to extend or adapt maritime salvage concepts like "law of finds" or "salvage rights" to space, but this would require new international agreements.
Commercial Space Act of 2015 (U.S.): Allows U.S. citizens to engage in the commercial exploration and exploitation of space resources, which could be seen as a step towards recognizing some form of salvage rights, though it's primarily about resource utilization.
Artemis Accords: While not directly addressing salvage, they promote responsible use of space resources, which might indirectly encourage debris management.

Future Legal Frameworks:

New Treaties or Protocols: There's a call for new or amended treaties to explicitly address space debris, including salvage operations, perhaps under the aegis of the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS).
Customary International Law: As practices evolve, new norms might emerge regarding the handling of space debris, potentially leading to customary law on salvage.
Public-Private Partnerships: Governments could partner with private entities to tackle debris, creating a framework where salvage might be incentivized.
Ethical and Environmental Considerations: Any legal framework for space salvage would need to consider the preservation of the space environment, protection of historical space sites, and equitable use of space resources.

Space salvage laws are currently in a nascent stage, where the principles need to balance legal, technical, economic, and ethical dimensions. The development of such laws will be crucial for managing space debris and ensuring the sustainable use of outer space.

Space Debris Ownership:

Ownership of space debris is governed by international space law, primarily through treaties established under the United Nations. Here's how ownership of space debris is currently understood:

Legal Basis:

Outer Space Treaty (1967):

Article VIII: This article is pivotal for space debris ownership. It states that "A State Party to the Treaty on whose registry an object launched into outer space is carried shall retain jurisdiction and control over such object, and over any personnel thereof, while in outer space or on a celestial body." This means:
Jurisdiction and Control: The state that registers a space object retains legal jurisdiction over it, even if it becomes debris.
Ownership: The ownership of the object, including its component parts, does not change due to its presence in space or return to Earth.

Registration Convention (1976):
Requires states to maintain a national registry of objects launched into space, which aids in establishing which state has jurisdiction and control over space debris.

Implications for Space Debris:

Permanent Ownership: Even if a spacecraft becomes non-functional or breaks apart, its ownership does not lapse. The original launching state retains legal rights over it.
Liability: Under the Liability Convention (1972), the state that launched the debris or from whose territory or facility it was launched remains liable for any damage caused by that debris.

Practical and Legal Challenges:

Fragmentation: When an object breaks apart, each piece technically remains under the jurisdiction of the state of registry, but tracking and managing such numerous fragments can be impractical.
Consent for Removal: Since debris is not considered abandoned, removing or altering its orbit requires permission from the state that retains jurisdiction over it.
Unclear Ownership: For very old debris or pieces from unknown origins, determining ownership can be challenging, especially if the original launching state no longer exists or if the object wasn't registered.
Debris from Unknown Sources: Some debris cannot be definitively traced back to a specific state, complicating legal accountability and ownership claims.

Current Practices and Discussions:

Debris Mitigation: States and private entities are increasingly adopting practices to mitigate debris, including deorbiting satellites at the end of their life, but this does not directly address ownership after they become debris.
Active Debris Removal (ADR): Companies and agencies working on ADR must navigate these ownership issues, often requiring diplomatic negotiations or legal agreements to proceed.
Artemis Accords: While not specifically addressing debris ownership, these accords encourage responsible behavior in space, including debris management, which implicitly deals with ownership by fostering cooperation.

Legal Scholarship and Proposals: There's ongoing debate about adapting or creating new laws:
Salvage Rights: Some propose a system similar to maritime law where salvaging space debris could be incentivized, but this would require new legal frameworks.
Abandonment: Concepts like declaring debris "abandoned" after a certain period or under specific conditions are discussed but not implemented.

Future Considerations:

New International Agreements: There might be a need for new treaties or amendments to existing ones to clarify or adapt ownership rules for space debris, especially with the rise in space activities.
Customary Law: As practices evolve, customary international law might begin to address these issues more concretely.
Private Sector Involvement: As private companies increasingly engage in space, their role in debris management, including ownership rights, will need clearer legal guidelines.
Ethical and Environmental Stewardship: The broader context of space as a shared resource might push for laws that prioritize environmental protection over strict ownership.

The issue of space debris ownership remains a complex intersection of law, technology, and international relations, requiring innovative solutions to ensure the sustainability of space activities while respecting established legal principles.

Space mining regulations are a burgeoning area of international space law, driven by the prospect of extracting resources from celestial bodies such as the Moon, asteroids, and other planets. Here's an overview of the current state, challenges, and future directions:

Existing Legal Framework:

Outer Space Treaty (1967):
Article II: Prohibits national appropriation by claim of sovereignty, but does not explicitly address resource extraction.
Article VI: Obligates states to authorize and supervise the activities of non-governmental entities in space, which includes mining operations.
Article XI: Encourages the use of space for the benefit and in the interests of all countries, without discrimination.
Moon Agreement (1979):
Article 11: Declares the Moon and its resources as the "common heritage of mankind," suggesting that any exploitation should be managed by an international regime. However, this treaty has not been ratified by major space-faring nations, limiting its impact.

National Legislation:

U.S. - Commercial Space Launch Competitiveness Act (2015):
Grants U.S. citizens the right to own, transport, and sell resources they obtain from space, while also clarifying that this does not assert sovereignty over celestial bodies.
Luxembourg - Law on the Exploration and Use of Space Resources (2017):
Establishes a legal framework allowing private companies to own resources extracted from space, aiming to become a hub for space mining activities.
United Arab Emirates - Federal Law No 12 of 2019:
Similar to Luxembourg and the U.S., it recognizes the right to own resources extracted from space.
Japan - Space Resources Act (2021):
Permits Japanese companies to explore and use space resources, including the Moon and asteroids.

International Initiatives:

Artemis Accords (2020):
While not a legally binding treaty, these accords, initiated by the U.S., include principles that support the extraction and utilization of space resources in compliance with the Outer Space Treaty. They are signed by numerous countries but not by all major space powers.
The Hague International Space Resources Governance Working Group:
Aims to develop governance principles for space resource activities, focusing on legal clarity, environmental protection, and fair benefit-sharing.

Challenges and Considerations:

Legal Ambiguity: The interpretation of the Outer Space Treaty regarding resource extraction varies, leading to debates over whether mining constitutes "appropriation."
International Cooperation: Lack of a universally accepted legal framework can lead to potential conflicts over resource rights.
Environmental Impact: There's no clear regulation on how to mitigate the environmental effects of mining operations in space.
Equity and Benefit Sharing: How to ensure that the benefits from space mining are shared globally, especially with nations not directly involved in the activity.
Liability: Determining responsibility if mining operations cause damage, either in space or if materials are brought back to Earth.
Technological Feasibility: The economic and technical viability of space mining is still uncertain, influencing regulatory considerations.

Future Directions:

New Treaties or Amendments: There might be efforts to create new international treaties or amend existing ones to explicitly address space mining, possibly under UN auspices.
Customary International Law: As more countries engage in or legislate for space mining, new norms might emerge through state practice.
Private Sector Influence: Increasing involvement of private companies could push for clearer regulations to ensure investment security.
Environmental Regulations: Future laws might focus more on preserving the space environment, similar to how terrestrial mining is regulated.
Resource Management Systems: Development of international bodies or mechanisms to manage space resources akin to the International Seabed Authority for ocean resources.
Ethical and Public Policy: Discussions around the ethics of space mining, including how it might affect future generations or the exploration of space for all of humanity.

The regulation of space mining is in a dynamic state, balancing the excitement of new economic opportunities with the need to preserve international peace, equity, and the pristine nature of space for future generations. As technology advances and more nations and private entities enter this field, the legal landscape will likely continue to evolve.

The Moon Agreement, officially known as the "Agreement Governing the Activities of States on the Moon and Other Celestial Bodies," was adopted by the United Nations General Assembly in 1979. Here are the detailed provisions and aspects of the Moon Agreement:

Key Provisions:

Non-Appropriation (Article II):
The Moon and its natural resources are the "common heritage of mankind." No part of the Moon can be subject to national appropriation by any claim of sovereignty, use or occupation, or by any other means.
Peaceful Purposes (Article 3):
The Moon shall be used exclusively for peaceful purposes. The agreement prohibits the establishment of military bases, installations, and fortifications, the testing of any type of weapons, and the conduct of military maneuvers on the Moon.
Environmental Protection (Article 7):
States must avoid harmful contamination of the Moon and other celestial bodies and should take measures to prevent adverse changes in the environment.
Scientific Research (Article 6):
The Moon shall be used for scientific investigation, promoting international cooperation in this field. States should share scientific information and should give priority to the needs of developing countries in this regard.
Resource Utilization (Article 11):
Common Heritage of Mankind: The Moon's natural resources are to be used for the benefit of all countries and all mankind.

International Regime: When exploitation of the Moon's resources is about to become feasible, an international regime should be established to govern such exploitation. This regime should ensure:
An equitable sharing by all States Parties in the benefits derived from those resources.
The orderly and safe development of the natural resources of the Moon.
The expansion of opportunities in the use of those resources.

Information Sharing (Article 5):
States must inform the United Nations and the public of the nature, conduct, locations, and results of their activities on the Moon.
Assistance in Distress (Article 10):
States Parties shall offer shelter in their stations, installations, vehicles, and other facilities to persons in distress on the Moon.
Responsibility and Liability (Articles 14 & 15):
States are internationally responsible for national activities on the Moon, whether carried out by governmental or non-governmental entities, ensuring these activities comply with the Agreement. There's also a provision for liability for damage caused on the Moon.
Consultation and Dispute Settlement (Articles 15 & 16):
States can consult if there's a belief that another state is not fulfilling its obligations. Disputes should ideally be settled through negotiation or other peaceful means.
Amendments and Withdrawal (Articles 17 & 20):
Any State Party can propose amendments, and withdrawal from the Agreement is possible with one year's notice to the UN Secretary-General.

Status and Criticism:

Entry into Force: The Moon Agreement came into force on July 11, 1984, after the fifth country (Austria) ratified it.
Limited Ratification: Only 17 countries have ratified the treaty, and none of these are major space-faring nations like the USA, Russia, or China, significantly limiting its practical impact.

Criticism:
Vagueness: The term "common heritage of mankind" and the lack of detail on how to establish the international regime for resource exploitation have been points of contention.
Redundancy: Critics argue that many of its provisions are already covered by the 1967 Outer Space Treaty.
Implementation: The lack of an actual international regime for resource management makes the treaty's provisions on mining largely theoretical.

Relevance: With the rise of new space powers and commercial space activities, the Moon Agreement is often cited in discussions about lunar governance but is largely sidelined due to its limited adoption.

Future Considerations:

Revisiting the Agreement: There's a call for revisiting or adapting the Moon Agreement to make it more relevant, possibly through an "Implementation Agreement" similar to what was done for the UN Convention on the Law of the Sea.
Artemis Accords: These newer principles challenge or complement the Moon Agreement by focusing on practical cooperation and resource use without explicitly endorsing or rejecting the treaty's framework.

The Moon Agreement represents an idealistic vision for managing lunar resources, but its practical application is hindered by the lack of participation from key space actors and the absence of detailed legal mechanisms to govern resource exploitation.
