Sydney Becomes a Cosmic Hub: Hosting the World's Space Leaders

Sydney is abuzz with anticipation as it readies itself to host the 76th International Astronautical Congress (IAC) from September 29 to October 3, 2025. The city is set to transform into a vibrant epicenter of space exploration, innovation, and wonder, as it welcomes a global congregation of up to 10,000 astronauts, scientists, engineers, and industry leaders.

A Celestial Gathering in Darling Harbour

The International Convention Centre at Darling Harbour will serve as the nucleus for this grand event. The congress, organized by the International Astronautical Federation, alongside the Space Industry Association of Australia, the Australian Space Agency, and the NSW Government, promises to draw attendees from over 80 countries.

But the excitement won’t just be confined to the walls of the convention centre. IAC 2025 Space Week will see the cosmos come alive all across Sydney, offering free, city-wide events that bring space exploration close to everyday life.

Space Week Festivities: Bridging Hearts with the Cosmos

The streets of Sydney will pulsate with space-themed activities. Imagine strolling through Martin Place and coming face to face with a colossal 10-metre inflatable astronaut. Or, picture yourself at the Powerhouse Museum, recording deep-space messages or enjoying dynamic demonstrations by scientists and engineers that bring the mysteries of the universe to life.

Fun, Learning, and LEGO Galore

As the week unfolds, IAC 2025 Space Day, occurring on October 3, promises to be an exhilarating experience for all ages. From mini lunar rover operations to sending portraits skyward to the Moon, the activities promise boundless joy. Powered By LEGO Play, workshops and a LEGO build zone will captivate young minds and inspire future endeavors in STEM fields.

A Stellar Opportunity for STEM Enthusiasts

Australian astronaut Katherine Bennell-Pegg, on behalf of the Australian Space Agency, voices her excitement for the chance to meet the public and encourage young Australians to engage in science and technology. Her invitation is heartfelt, “Space is not just up there; it’s here in Australia, integral to everyday life. IAC 2025 is a once-in-a-generation chance to inspire future generations towards careers among the stars.”

Knowledge Enriched at the Sydney Science Festival

The Powerhouse Museum extends the celebrations by integrating its Sydney Science Festival into the proceedings, culminating in a special science day at Parramatta Square on October 4. Engaging activities, including spacesuit patch design and a custom Fortnite lunar mission game, await eager participants.

A Commitment to Innovation and Unity

Lisa Havilah, Chief Executive of the Powerhouse Museum, captures the essence of the event, “This landmark global event epitomizes our shared commitment to celebrating science, innovation, and the visionaries shaping our future.” As stated in Australian Manufacturing, the International Astronautical Congress will indeed turn Sydney into a cradle of cosmic curiosity and collaboration.
