Founded in 1951, the International Astronautical Federation (IAF) is one of the world’s most respected and longstanding international organizations in the space sector, bringing together 604 members from 82 countries, including space agencies, private sector representatives, associations, unions, universities, museums, and research institutions.

The International Astronautical Congress (IAC), organized annually by the IAF, is one of the most prestigious and widely attended global events in the space community, bringing together all stakeholders working in space agencies and space technologies, and shaping the future of the sector. Throughout the congress, there are international exhibition areas, high-level protocol sessions, company showcases, academic and technical presentations on the latest developments in the future of space, and platforms sharing the most recent advancements in the industry.

The 77th International Astronautical Congress (IAC 2026 Antalya) will be held for the first time in Türkiye, on 5–9 October 2026 at the Antalya Nest Congress Center, under the coordination of the Ministry of Industry and Technology, hosted by the Turkish Space Agency (TUA), and co-hosted by SAHA Istanbul. In this major congress that brings together the global space ecosystem, our aim is to turn IAC 2026 Antalya into a worldwide success story and to maximize the scientific, technological, and economic benefits for our country by uniting all stakeholders of Türkiye’s space ecosystem.

With more than 10,000 registered visitors and the participation of numerous international companies, IAC 2026 will offer a unique opportunity to showcase the studies, products, and technologies that will shape the space ecosystem, as well as to provide academic gatherings and knowledge exchange platforms. Hosting this distinguished event in Türkiye will contribute internationally to the strategic goals of our National Space Program particularly “Enhancing Space Awareness” and “Developing the Space Ecosystem” and will strengthen our vision for the Century of Türkiye (Türkiye Yüzyılı).
