By holding countries accountable for their unsustainable actions in outer space, this collective effort promotes responsible behavior and fosters a sense of responsibility among all participating nations.4

Accountability for Space Debris Retrieval/Removal

International organizations have consistently introduced new initiatives to monitor, regulate, and delineate the scope of outer space activities. These initiatives encompass the following organizations and their respective efforts:

Figure1. Individual initiatives by Quad nations for space debris management (author’s compilation)

  • Outer Space Treaty (OST) (1967): The OST serves as the cornerstone of international space law, establishing that outer space, including the moon and celestial bodies, is beyond the appropriation of any nation and should be utilized for the common benefit of all countries. The treaty also holds parties are liable for damage caused by space objects they launch.
  • The Rescue Agreement (1968): This agreement primarily addresses the rescue and return of astronauts and the return of launched objects that return to Earth. While not directly dealing with space debris removal, it is part of the broader legal framework governing space activities.
  • Liability Convention (1972): This convention outlines the liability of launching states for damages caused by their space objects on Earth’s surface or to other spacecraft. However, it does not specifically address space debris removal.
  • Registration Convention (1975): This convention requires states to register their space objects with the United Nations, aiding in the identification and tracking of space debris. Although it does not explicitly focus on debris removal, it plays a crucial role in enhancing space situational awareness.
  • UN Committee on the Peaceful Uses of Outer Space (COPUOS) and Inter-­Agency Space Debris Coordination Committee (IADC) Guidelines (1993): COPUOS and IADC have jointly developed guidelines for the long-­term sustainability of outer space activities, including recommendations for debris mitigation and prevention. These guidelines, although non-­binding, represent international consensus on best practices for managing space debris.

Together, these international agreements and guidelines form a comprehensive legal framework for regulating outer space activities, addressing issues of ownership, liability, registration, rescue, and the mitigation of space debris.

However, have primarily focused on identifying and raising awareness about the issue of space debris, without providing concrete mechanisms for debris removal or resolving the accountability aspect of debris management. The existing regulations have certain drawbacks, including the following:

  1. Lack of specific regulations: The current legal framework lacks specific regulations dedicated to space debris removal, resulting in regulatory gaps and unclear responsibilities for debris management.
  2. Nonbinding guidelines: The guidelines issued by COPUOS and IADC , while offering valuable recommendations, are not legally binding. This voluntary nature may lead to inconsistent implementation and adherence to best practices among space actors.
  3. Ambiguity in liability and responsibility: The existing legal framework does not provide clear definitions regarding the responsibility for space debris removal and the associated costs. This ambiguity can lead to inaction or disputes among states regarding their obligations.
  4. Technical challenges: Space debris removal poses significant technical challenges, and the current legal framework falls short in providing guidance on how to address these challenges or support the development of debris removal technology.
  5. Jurisdiction and ownership: The legal framework does not sufficiently address jurisdictional and ownership matters related to space debris. This lack of clarity complicates the process of removal and disposal, especially when debris ownership is unclear or when multiple parties are involved.
  6. Nonstate actors and commercial activities: The current legal framework primarily focuses on state responsibility, which may not adequately address the increasing presence of nonstate actors and commercial space activities. Additional considerations and regulations are necessary to address space debris generated by these entities.
  7. Limited international cooperation mechanisms: The existing legal framework lacks comprehensive mechanisms to foster international cooperation in space debris removal. Given the global nature of the problem, enhanced collaboration among nations is essential to effectively address the issue.
  8. Uncertainty regarding classification and ownership: The Outer Space Treaty does not provide clear guidance on the classification and ownership of space debris, making it challenging to determine ownership rights and responsibilities. This ambiguity can hinder debris removal efforts.5

The Space Treaty prohibits states from interfering with or disrupting space objects under the jurisdiction of others. This raises questions about the extent of jurisdiction over space objects and the removal of debris generated by other entities. Additionally, there is no explicit clarification on unclaimed debris and how it should be addressed within the legal framework.6

Addressing these limitations and ambiguities within the legal framework is crucial for effective space debris management. Future efforts should focus on developing specific regulations for debris removal, clarifying liability and responsibility, fostering international cooperation, and providing guidance on technical challenges and ownership issues to ensure a sustainable and secure space environment.

International Cooperation and Potential Solutions

Despite the existence of various international initiatives, the lack of strict and binding rules remains a significant challenge in preventing and removing space debris and addressing the associated risks to space activities. There is a pressing need to establish clear accountability for space debris within international law and agreements. This entails defining the responsibilities of relevant stakeholders in preventing the creation of new debris, mitigating risks posed by existing debris, and addressing damages caused by space objects. Several incidents in the past two decades have underscored the criticality of space debris management and the imperative for accountability:

  • China’s antisatellite test (2007): In 2007, China conducted a highly controversial antisatellite missile test, deliberately destroying one of its own weather satellites, the Fengyun-1C. This test resulted in the creation of more than 3,000 trackable debris fragments, along with numerous smaller pieces, substantially augmenting the population of debris in low Earth orbit. The repercussions of this incident serve as a stark reminder of the urgency to establish accountability and deter reckless actions that contribute to the proliferation of space debris.
  • Iridium 33 and Cosmos 2251 collision (2009): In 2009, a significant collision occurred between two satellites: the operational commercial satellite Iridium 33 owned by the United States and the nonoperational government-­owned satellite Cosmos 2251 from Russia. The collision resulted in the fragmentation of both satellites, generating a multitude of debris fragments. This incident serves as a poignant reminder of the imperative to establish accountability for effectively mitigating the risks associated with existing debris, including nonoperational satellites.
  • Reentry of spacecraft: Notable instances of spacecraft reentry, such as Russia’s Mir space station in 2001, China’s Tiangong-1 space laboratory in 2018, components of the Chinese Long March 5B rocket, and the International Space Station’s (ISS) evasive maneuver to avoid the approaching Russian satellite Cosmos 1408, have raised concerns regarding the risks involved. Although no severe injuries or significant property damage were reported, these incidents underscore the potential dangers associated with uncontrolled reentries and emphasize the necessity for accountability in managing space debris.7

Incorporating accountability into international laws will contribute to the following:

  • Prevention and mitigation: By establishing clear accountability, countries and other actors will be motivated to proactively prevent and mitigate space debris, recognizing the potential consequences and liabilities associated with irresponsible actions. This will encourage the adoption of best practices, technological advancements, and collaborative efforts to reduce debris generation and enhance space debris mitigation measures.
  • Compensation for damages: With clear accountability, determining liability and allocating responsibility for damages caused by space debris becomes more straightforward. This clarity facilitates the process of seeking compensation from the responsible party, ensuring that those impacted by debris-­related incidents can be appropriately compensated for any harm or losses incurred.
  • Debris removal: Accountability incentivizes entities to actively participate in debris removal efforts. When accountable for objects they launch into space, even after those objects become debris, there is a direct interest in supporting or undertaking debris removal initiatives. This can drive the development of debris removal technologies, collaborative missions, and international cooperation to address the accumulation of space debris.
  • Foster international cooperation: Accountability plays a vital role in fostering international cooperation on space debris management. Clear accountability measures encourage countries to align their interests and cooperate in sharing technology, data, and expertise to effectively manage space debris. This collaboration can include joint research and development initiatives, information sharing platforms, and the establishment of common standards and guidelines for responsible space activities.

By integrating accountability into international laws and agreements, these actions will help prevent and mitigate space debris, ensure fair compensation for damages, drive debris removal efforts, and foster international cooperation in addressing the challenges posed by space debris.
