For this year’s Sydney Science Festival, Powerhouse Museum presented a special edition in collaboration with the International Astronautical Congress (IAC) and the Australian Space Agency as part of IAC 2025 Space Week. Running from 27 September to 4 October 2025, the festival brought to life a dynamic program celebrating science, innovation, and the boundless possibilities of space exploration.
Whether listening to an astronaut share their journey or building colourful kites with their own hands, visitors experienced science not as something distant in the sky, but as a space they could touch, feel, and immerse themselves in across Parramatta Square, PHIVE and Centenary Square.

Every part of the festival was designed to spark genuine curiosity, creating moments where people could build, ask questions, and discover together. Our staunchly incredible team of thirteen volunteers went above and beyond to make this possible.
You could spot them everywhere — kneeling beside families at the kite-making tables, chatting with children about rockets, or helping visitors uncover the layered stories behind each astronaut’s journey.

It was a full, fast-moving event, yet every volunteer adapted seamlessly, jumping into every task with focus, generosity, and bright energies.

A huge thank you to everyone who showed up with heart, hustle, and an open spirit to make this such a stellar success. With over 10,000 people joining in on the fun throughout the day, your energy and dedication shaped the experience for every single one of them — and filled it with so much colour.
Truly the backbone of this program and we couldn’t have done it without you!
