Under the motto “The World Needs More Space”, the aim of IAC 2026 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.

We aim to inspire a dialogue that transcends borders, encouraging innovative solutions that harness the benefits of space exploration while safeguarding it for future generations. The congress will feature engaging discussions, groundbreaking presentations, and collaborative workshops that seek to unite our shared aspirations for the future of space.
