Armstrong, la lune et l'espace (E25)

In Ancient Greece it was thought that a ship could be catapulted up to the moon by means of a tornado. The first person to have the idea that this would only be possible with a controlled rocket drive was the Russian Ziolkowsky. He made very precise calculations, but nobody believed him at his time. Not until 1945, the technical development was ready for a race to the moon between the Americans and the Russians. Gagarin was the first man in space, Leonov went floating in space and finally in 1965, Armstrong as the first person on earth set his foot upon the ground of the moon. (iTunes)
