The International Astronautical Federation (IAF) has announced a new milestone in its history: the 76th International Astronautical Congress (IAC 2025), taking place in Sydney has already received over 3,000 Early Bird registrations — surpassing the previous record held by IAC 2024 in Milan.
Held under the theme “Sustainable Space: Resilient Earth,” IAC 2025 will serve as a global platform for fostering dialogue, collaboration, and innovation on space-based solutions for Earth and beyond.
Organized by the International Astronautical Federation (IAF), hosted by Space Industry Association of Australia (SIAA) and co-hosted by Australian Space Agency and NSW Government, IAC 2025 will welcome thousands of space professionals, decision-makers, academics, industry leaders, astronauts, and students from across the globe. The comprehensive programme will feature over 200 technical sessions, high-level plenaries, ministerial and agency roundtables, and the IAF Global Networking Forum (GNF) — offering unmatched opportunities for knowledge exchange, strategic partnerships, and global visibility.
As one of the world’s most iconic and dynamic cities, Sydney provides a spectacular backdrop for this landmark event, combining world-class infrastructure, diverse culture, and a vibrant aerospace ecosystem.
Space and Defence – MySecurity Media are IAF and IAC media partners.
