Why do we explore space? | Third Space

“I don't think the human race wiill survive the next thousand years, unless we spread into space. There are too many accidents that can befall life on a single planet. But I'm an optimist. We will reach out to the stars.”
― Stephen Hawking, Theoretical Physicist

For thousands of years, humanity has been shaped by the vast cosmos above. Neil Armstrong’s “Giant leap for mankind” realised the imagination of ancient mariners, mathematicians, priests and even farmers. Why is space the stuff dreams are made of? What have we learned about ourselves and our place in the universe since 1969? Where to next? Join our guests as we take you on a journey of imagination, reality, and 300 million kilometres.

This Bigger Question special event reflected on 50 years since the moon landing.
