Quirks & Quarks is celebrating the 50th anniversary of Armstrong and Aldrin putting the first human boot prints on the Moon. We’ve collected reminiscences and reflections from Canadian astronauts and from scientists across a diverse range of fields. They explain how the historic Apollo 11 landing inspired them and shaped the future that they’re continuing to create.

We're taking a little summer break, but check back for a new program celebrating the 50th anniversary of the moon landing on July 20.
