Summary of "The Security of Space Activities"

Core Content

The document discusses the growing concerns regarding the security and sustainability of space activities, particularly in Earth orbit, and outlines the challenges posed by orbital debris, potential militarization, and resource management. It emphasizes the need for an international regulatory framework to ensure the safe and secure use of outer space.

Main Viewpoints

• Security and Sustainability are Interlinked: The paper argues that improving security in space also enhances safety and long-term sustainability, and therefore, these aspects must be addressed together.
• Rapid Growth of Space Actors: Over 60 states and regional organizations operate satellites in Earth orbit, with a significant increase in private companies. This leads to increased crowding in low Earth orbit (LEO) and the geostationary orbit (GEO) region.
• Orbital Debris is a Major Risk: The number of tracked space objects has grown significantly, with most being non-functional debris. The 2007 Chinese ASAT test and the 2009 Iridium-Cosmos collision have exacerbated the problem by creating large debris fields.
• Potential for Outer Space to Become a Battlefield: While no weapons have been deployed in space, ground-based weapons can target spacecraft, and non-kinetic threats, such as jamming and cyber attacks, are already in use.
• Need for Better Regulation: The International Telecommunication Union (ITU) manages the radio spectrum and orbital slots, but lacks enforcement mechanisms. The IADC has played a key role in developing debris mitigation guidelines, but international consensus on security measures remains elusive.

Key Information

• Orbital Debris Statistics:

  • As of the end of 2015, 22,000 objects are tracked in Earth orbit.
  • 17,255 are catalogued, of which 23% are functional or non-functional spacecraft.
  • 77% are debris, including 11.5% spent rocket stages, 11.5% mission-related objects, and 54% fragments.
  • The 2007 Chinese ASAT test created 30,000 debris pieces, many still tracked in 2015.
  • The 2009 Iridium-Cosmos collision generated over 1,500 debris pieces.

• International Efforts:

  • The IADC has been a leading body in space debris mitigation, with guidelines adopted in 2007.
  • The UN COPUOS has been involved in long-term sustainability discussions, but progress has been slow.
  • The EU proposed an International Code of Conduct (ICOC) in 2007, but faced resistance due to perceived lack of inclusivity and UN involvement.
  • Russia and China proposed a Draft Treaty on the Prevention of the Placement of Weapons in Outer Space (PPWT), which was not widely supported due to its lack of verification mechanisms and failure to address ground-based ASAT weapons.

• Challenges:

  • Lack of enforcement in international agreements.
  • Political resistance to certain proposals, especially from emerging space nations.
  • Technological advancements increase the risk of militarization and cyber threats.
  • Space weather remains a risk, though it is not directly related to the number of space objects.

• Recommendations:

  • The EU should adopt a new approach to the ICOC proposal, ensuring inclusivity and addressing concerns of emerging nations.
  • A consensus-based, technically grounded framework is needed to ensure long-term sustainability and security in space.
  • The ITU needs to strengthen its enforcement powers to manage the radio spectrum and orbital slots more effectively.

Structure of the Paper

I. Are Space Activities Secure and Sustainable?

• Highlights the increasing risks due to overuse and neglect.
• Compares the situation to ocean exploitation in the 19th and 20th centuries.
• Emphasizes the need for a unified approach to security, safety, and sustainability.

II. Some Numbers

• Lists key statistics on space launches, satellites, and debris.
• Notes the increase in satellite launches and the multiplication of spacecraft per launch.

III. Main Causes of Concern

• Discusses orbital debris, militarization, radio spectrum management, and cyber threats.
• Explains the impact of debris on operational satellites and the velocity issue in LEO.

IV. International Initiatives

• Describes the COPUOS and IADC efforts.
• Notes the development of guidelines and the blockage by Russia in 2016.
• Highlights the COPUOS Working Group established in 2010 to address long-term sustainability.

V. EU Proposal for an International Code of Conduct

• Details the EU's ICOC initiative, including consultations and draft versions.
• Points out resistance from some states, especially due to perceived exclusivity and lack of UN involvement.

VI. Russia and China's PPWT Proposal

• Describes the PPWT initiative, which aims to prevent weapon deployment in space.
• Notes US opposition and lack of verification mechanisms.
• Highlights the ongoing push by Russia and China to shape international norms.

VII. UN Group of Governmental Experts

• Reviews the history of TCBMs in the UN framework.
• Notes the unanimous adoption of the 2010 resolution and the establishment of the GGE.
• Emphasizes the need for a comprehensive and enforceable framework.

Conclusion

The paper concludes that while some progress has been made in debris mitigation, the international community still lacks a unified and enforceable regulatory framework for space security and sustainability. It calls for a more inclusive and technically sound approach to address the growing concerns in outer space.
