The world was in awe of the moon landing, but a Kiwi astronomer says the real significance was in the rocks they brought back.
It's 50 years on Sunday since NASA's Apollo 11 mission put the first humans on the moon.
Canterbury University Astronomer Alan Gilmore says he listened to the landing on the radio like most of the world.
He told Kate Hawkesby the results from the lunar rock samples were what totally changed his perspective of the solar system.
Nasa has announced they are aiming to send humans back to the Moon by 2024, a mere five years from now.
