Long before Mars lander Curiosity was even a glimmer in an engineer’s eye, Carl Sagan was talking about exploring Mars. In 1977, he gave a series of six lectures for kids about exploring our solar system. Here they are, in order. Each is about 60 minutes long. You can also sign up for free and watch them all at The Royal Institution online.
Editor’s note: These videos have been removed from the post due to a copyright violation claim from the Carl Sagan estate. Check them out at the site linked above, however. They are fantastic.
