“Astronaut Stories Australia is a keynote series of events run by the AIAA to bring the stories, passion and inspiration of the world’s astronauts to life. The event aims to increase public interest in space-based activities, to inform the public of the value of science and technology, and to motivate support to explore the boundaries of our knowledge.”
There are two events. There’s an evening event of astronaut stories and there’s a workshop for high school students during the day.
The Sydney event is on 21st September 2017.
There are more details and information on how to book – it appears to be free – on the website.
