Call for Hosting the International Astronautical Congress 2023

The call for submission of proposals is now open.


The IAF is calling for expressions of interest from member organizations to host the annual International Astronautical Congress in 2023.

The IAC is the one time of the year when all space actors come together. Global, multidisciplinary and covering all space sectors and topics, it offers everyone the latest space information, developments but above all contacts and potential partnerships. Each year, the IAC changes country, theme and local organiser, enabling all to learn more about, and be a part of the world space scene.

In recent years the event has attracted between 4500 and 6500 participants including 3500 full paying participants, retired participants and press representatives as well as more than 1500 students and young professionals. The congress itself is a five-day event with defined pre- and post-congress associated events.

We look forward to receiving your proposals.

Note: the IAF member organization proposing to host an IAC must demonstrate that it meets the above requirements through the creation of a consortium or other entity with sufficient organization skills, financial backing, human resources and legal structure to meet this requirement.

In this case, the proposed organization must include in its proposal:
