That is true - it is the same with space. They put a man on the moon 40 odd years ago and now they are still struggling to launch a shuttle without it blowing up.
The moon trips were single shot with the sole purpose of putting someone on the moon before the Russians. Additionally, only a tiny part of the rocket had to re-enter the atmosphere to return the crew.
