International Astronautical Congress 2026

The 77th International Astronautical Congress (IAC 2026) will take place in Antalya, Türkiye, from 5–9 October 2026 — marking the first time in history that the event will be hosted in Türkiye. Known for its rich cultural heritage, warm hospitality, breathtaking Mediterranean coastline, and vibrant innovation ecosystem, Antalya will offer a unique backdrop to one of the world’s most prestigious space gatherings. This year’s edition of the IAC is hosted by the Turkish Space Agency (TUA) and co-hosted by the SAHA Istanbul Aerospace Cluster.

The IAC 2026 theme, The World Needs More Space, frames a programme inviting visionary ideas, innovative technologies, and pioneering research. In an age where the exploration and utilization of outer space are more crucial than ever, our motto emphasizes the imperative of maintaining a secure, accessible, and collaborative environment in the cosmos.

The congress will serve as a platform to highlight the importance of space as a shared resource that must be preserved for peaceful use, fostering international cooperation across all nations, regardless of their developmental status. The core focus of “The World Needs More Space” is to advocate for the sustainable and equitable exploration of space. As more countries and diverse stakeholders join the global space economy, it is essential to ensure that space remains an open frontier for all. The IAC 2026 will address pressing issues surrounding space security, exploration, and the ethical implications of our activities beyond Earth.

The IAC 2026 promises to be an unforgettable gathering that will shape the future of space exploration and utilization. We invite you to join us in Antalya and contribute to the dialogue on how we can collectively ensure that the cosmos remains a realm of opportunity, inspiration, and unity for generations to come.
