The Saturn V rockets were the workhorses of the US Space Program [sic] in the late 60s and early 70s. And the subject of a great Inspiral Carpets song in the mid 90s. They were huge things – 111 metres in height (that’s the equivalent of a 36 storey building) and with a mass of 2.8 million kilograms (that’s the equivalent of about 470 elephants).
With great size and great escape velocity comes great fuel requirement as well:
The Saturn V rocket’s first stage carries 203,400 gallons (770,000 liters) of kerosene fuel and 318,000 gallons (1.2 million liters) of liquid oxygen needed for combustion.
At liftoff, the stage’s five F-1 rocket engines ignite and produce 7.5 million pounds of thrust.
But what does that actually mean? Sometimes, figures are difficult to interpret without context. That’s why I used the 36 storey building and the 470 elephants above.
In fact, it worked so well, I think I’m going to use the elephants again:
Yes. That’s a quick mock up of Saturn V fuel consumption expressed in elephants. And it’s a lot of elephants.
I trust everything is clear now.
