Wind the clock back to 1971. On the eve of the Mariner 9 launch, Ray Bradbury took part in a panel discussion at Caltech with Carl Sagan, Arthur C. Clark, Bruce Murray, and Walter Sullivan. These clips were issued by NASA's Jet Propulsion Lab to commemorate Bradbury's life. He recently passed away at the age of 91. Forgive the distorted audio... and enjoy his smart and extremely funny comments.
