This is something you have to see to believe. Saying that it’s unbelievably massive just doesn’t do it justice. This is the Saturn V Rocket, the most powerful rocket ever built and operated. It’s design played a major role in successfully transporting and landing American astronauts on the moon during the Apollo missions. Over 36 stories tall, this Saturn V is one of only three left in existence. And if we ever needed to go back to the moon, chances are this would be the rocket to get us there.
