Outer Space Security Conference 2023

13-14 September 2023
Outer Space Security Conference 2023

UNIDIR’s Outer Space Security Conference is an annual flagship event that provides a unique forum for the diplomatic community — as well as experts from military, industry and academic backgrounds — to jointly consider challenges and solutions related to security in outer space.

Space security has become increasingly important, with outer space technology enabling many of the services that humankind relies on. In this sense, space is increasingly critical to modern life on Earth. However, there is growing concern that, as space becomes more economically and strategically important, it could become a theatre for conflict, with devastating effects in space and on Earth. This challenge will become more complex as technology continues to develop and diffuse, creating new space security issues.

The international community has attempted to address these concerns through various initiatives. However, space security is an evolving process, and no single initiative will be able to address all of the complex issues related to the security of outer space. In this regard, the international community has recognized the need for ensuring the complementarity of different measures and building common understandings to effectively achieve space security.

The 2023 Outer Space Security Conference provided an informal opportunity for the space security community to consider current challenges, as well as how various initiatives and processes can be brought together in a mutually reinforcing complementary manner to achieve the goals of PAROS and foster space security.

11.00 – 12.30 CEST  Panel 1 — Mapping space threats, risk and challenges

Space related technologies are advancing and diffusing around the globe creating significant opportunities to address societal challenges in several different areas. However, these technologies can also be employed for hostile purposes by states and potentially non- state actors. This first session set the scene with an overview of the value of space assets for development and present different perspectives of threats, risks, and challenges to space security.

13.30 – 15.00 CEST — Panel II — Taking stock of multilateral efforts to build space security

In recent years, many different mechanisms and processes have been proposed to address space security concerns and to achieve the goals of PAROS. Illustrative examples include the Open-Ended Working Group established under the UN General Assembly resolution 76/231 on Reducing Space Threats through Norms, Rules and Principles of Responsible Behaviours, which came to a close on 1 September; the 2019 Group of Governmental Experts established under UN General Assembly resolution 72/250 on Further Practical Measures for the Prevention of an Arms Race in Outer Space; the 2013 Group of Governmental Experts established under UN General Assembly resolution 65/68 on Transparency and Confidence-building Measures in Outer Space Activities; the draft treaty on the Prevention of the Placement of Weapons in Outer Space and of the Threat or Use of Force Against Outer Space Objects; international initiatives and political commitments on no first placement of weapons in outer space, and on destructive direct-ascent anti-satellite missile testing, and the 2023 UN Disarmament Commission recommendations to promote the practical implementation of transparency and confidence-building measures in outer space activities with the goal of preventing an arms race in outer space. This panel analysed such initiatives and consider the impact of these measures as well as how they can complement and inform future steps to achieve space security.


  • Hellmut Lagos (Consul of Chile to La Paz, Bolivia & Chair of the OEWG)
  • Clive Hughes (Head of Space Security and Advanced Threats, FCDO)
  • Carine Claeys (EU Special envoy for Space / Head of the Space Task Force)

15.30 – 17.00 CEST — Panel III — Preparing for success in future multilateral space security initiatives

Further work will be required to develop and sustain space security in the future, including through the work of Group of Governmental experts on Further Practical Measures for the Prevention of an Arms Race in Outer Space, which will consider and make recommendations on substantial elements of an international legally binding instrument on PAROS, including, inter alia, on the prevention of the placement of weapons in outer space. This panel considered how best to build on past initiatives and prepare for the success of this and other future initiatives.

Space security, safety and sustainability cannot be achieved through any single initiative. Multiple approaches and tools are required. This panel looked at practical tools and approaches to building space security, safety and sustainability that can complement and support multilateral process, including the registration of space objects, notifications of launches, as well as others as the sharing of information on space security doctrines and policies, and analysis of how they could be implemented, used, monitored and verified.

13.00 – 14.30 CEST — Panel V — The importance of global diversity, inclusiveness and multilateralism for space security

Globally diversity, inclusiveness and multilateralism should be taken into account as the international community works towards the establishment of mechanisms to achieve PAROS. This panel considered how globally diverse multilateral and inclusive approaches —through international, intra– and inter-regional cooperation— can contribute to space security.

15.00 – 16.30 CEST — Panel VI — Building common understandings between stakeholders

Achieving space security hinges on the ability to create a common understanding among States and stakeholders to pave the way towards a more secure, transparent and trusting space environment and ensuring that the exploration and use of outer space is carried for peaceful purposes, wherein different actors, instruments, and processes work towards shared goals of PAROS and the preservation of space for peaceful purposes in a mutually reinforcing manner. This panel brought together different representatives of the stakeholder communities to discuss means to exploit synergies and foster common understandings with a view to achieving PAROS and bolstering space security for all.
