2021 Outer Space Security Conference

When: Monday, September 27, 2021

to Tuesday, September 28, 2021

Where: Geneva, Switzerland (virtual participation available)

2021 Outer Space Security Conference

Space is increasingly critical to modern life on Earth. However, there is growing concern that as space becomes more economically and strategically important, tensions between different space actors could lead to conflict. Such a conflict could have devastating consequences for humankind.  

To better understand and address issues related to space security, the United Nations Institute for Disarmament Research (UNIDIR) is pleased to invite you to the 2021 Outer Space Security Conference. This one-and-a-half-day flagship event provides a unique forum for the Geneva-based diplomatic community—as well as visiting experts from military, industry and academic backgrounds—to jointly consider challenges related to security in outer space and to exchange ideas regarding solutions.

UNIDIR encourages the participation of diplomats, national representatives, policymakers, as well as academics, practitioners and other experts working on or interested in issues pertaining to space security.


27 September 11:00-17:30 CEST - 28 September 10:00-18:00 CEST

This event will be held in person, Room XXI of the Palais des Nations, Geneva. It will also be livestreamed, with the possibility of interactive participation.


Participants can join the event either in-person or virtually:

DAY 1 – The Challenges

  • Keynote address
    • Why the international community needs to build a sustainable space security architecture
    • The importance of a peaceful space domain
  • Panel I — From the enactment of the Outer Space Treaty to now: how has the space domain changed? 
    • The Outer Space Treaty entered into force in 1967 during the Cold War, a time of great geopolitical tensions in the international community. The drafters hoped that it would aid in preventing those tensions from reaching the space domain, a feat that the Outer Space Treaty failed to fully achieve. This led to the emergence of PAROS, an objective that has not changed much since it originated more than 40 years ago. This panel will discuss how the space domain has changed, particularly in recent years with the emergence of new State actors as well as non-governmental entities, such as commercial companies, and how that affects arms control and disarmament efforts.
  • Panel II — Space threats and challenges 
    • Over the past year, several countries have carried out tests of counterspace technology, as well as ambiguous operations that have raised alarms and incited protests and criticisms. Many States’ space policies continue to shift towards treating outer space as a contested, operational, or even a warfighting, domain. This panel will discuss drivers of an arms race in outer space including geopolitical rivalries, enabling capabilities, and the accelerated development of arms.
  • Panel III — The dual-use nature of space assets and their potential impacts on outer space security
    • States have come to rely on dual-capable satellites to serve both civilian functions and military needs. This trend has increased with the emergence of commercial actors. Furthermore, it is often difficult to discern whether the military capabilities of a satellite are for defensive or offensive purposes. This ambiguity gives space actors considerable freedom of action, but it also increases the potential of threats to their interests and technology in space. This panel will explore the implications of dual-use space technologies for space security, as well as the role played by intent and behaviour in the use of these assets.

DAY 2 – Tools and Approaches to enhancing security in Outer Space

  • Panel IV — Non-binding norms and Transparency and Confidence-Building Measures (TCBMs)
    • In recent years, several countries have proposed the implementation of non-binding norms to address space security related issues, including UNGA Resolution 75/36 on “Reducing space threats through norms, rules and principles of responsible behaviours”, and proposals around “Transparency and confidence-building measures in outer space activities”, “No first placement of weapons in outer space”, and 3SOS. Also relevant are norms not built specifically for the space domain, but that directly affect it, such as The Hague Code of Conduct against Ballistic Missile Proliferation (HCOC). This panel will examine the role and limits of non-binding measures in addressing concerns related to space security. 
  • Panel V — Legally binding measures 
    • Legally binding measures have traditionally been viewed as the ‘gold standard’ for arms control and disarmament mechanisms. Although there are currently no legally binding treaties on the issue of preventing an arms race in outer space, several members of the international community have put forward proposals over the years. This panel will discuss the process needed to reach a successful binding agreement and consider the key issues that such an instrument must consider.
  • Panel VI — Verification mechanisms: how technology can aid in ensuring compliance with space security regulations
    • Technological advances, particularly in the field of space situational awareness, are enabling a clearer and more detailed picture of space activities, particularly in geosynchronous orbit. This panel will discuss how, through the use of these ever-developing technologies, it could become possible to better understand the actions of others in space and more effectively verify certain types of agreements on space security challenges.
  • Panel VII — Wider governance measures: the role of non-governmental entities and non-traditional stakeholders in contributing to space security
    • States no longer are the only stakeholders in space. Non-governmental entities, such as commercial space companies, have become particularly prominent in recent years. Collaboration with these non-traditional stakeholders, as well as with academic research could lead to novel and diverse approaches to discussing space security. As dynamics continue to change in the space environment, their input could provide great value to the objective of preventing an arms race in outer space, and identifying its drivers in order to manage and mitigate them. This panel will explore how collaboration with and inclusion of these non-traditional stakeholders can aid in achieving the goals of PAROS.
