The Space Law Conference, which follows a series of 15 annual Conferences and Workshops, is organized virtually from Vienna from 28-30 November 2023

International and regional cooperation in the peaceful uses of outer space helps to bring the benefits of space technology applications to a wide circle of stakeholders, both governmental and non-governmental, and to intensify and diversify national space programmes. Policy and regulatory frameworks at the national, regional and international levels are of paramount importance for providing the necessary basis for States, particularly developing countries, to meet development goals and address challenges to sustainable development. In this connection, it is necessary to continue to strengthen the linkages between international space law and the conduct of space activities.

The following main areas will be addressed: 

  • The legal regime of outer space and governance at the multilateral level
  • Principles found in Articles I-XII of the Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies (Outer Space Treaty) and reasonably foreseeable space activities within the context of those principles

As a general background, each year, in its resolutions on international cooperation in the peaceful uses of outer space, the General Assembly reaffirms the importance of international cooperation in developing the rule of international law, including the relevant norms of international space law and their important role in international cooperation for the exploration and use of outer space for peaceful purposes, and of the widest possible adherence to international treaties that promote the peaceful uses of outer space in order to meet emerging new challenges, especially for developing countries. The Assembly recognizes that all States, in particular those with major space capabilities, should contribute actively to the prevention of an arms race in outer space with a view to promoting and strengthening international cooperation in the exploration and use of outer space for peaceful purposes.

In today's world, where the number of actors that engage in space activities increases every day, it is of the utmost importance to ensure that all actors comply with the requirements of international space law in developing international and regional space cooperation.

The successful implementation and application of the international legal framework governing space activities depend on the understanding and acceptance of that framework by policymakers and decision makers. The availability of professionals who can provide suitable legal advice and disseminate information and knowledge about space law, in particular in developing countries, depends on the availability of adequate education opportunities in space law and policy.

This Conference will be held in order to promote adherence to the five United Nations treaties on outer space and to assist States in building their capacity in space law, and thus help them to meet the Sustainable Development Goals.
