In 1961, President John F. Kennedy promised to land a man on the moon by the end of the decade, in a speech to Congress. Although the Soviets denied it, they too were trying to become the first to land men on the moon.
Apollo ran from 1961 until 1972.
Building on what they learned from the Gemini project, NASA built the biggest rocket the world has ever flown.
The Saturn family of rockets were multistage liquid-fuelled rockets capable of taking crew and lunar equipment to the moon. The Saturn V stood taller than the Statue of Liberty.
Because it was a multistage rocket, it had three parts. Each stage would burn its engines until it ran out of fuel and then separate from the rocket. Then the engines on the next stage would fire.
The first stage would take the rocket 68km high, then second stage carried the rocket almost into orbit and the third stage would take the rocket into orbit and accelerate it towards the moon.
