It dominates whatever is around it.

You can feel as it comes by, you know, it shakes the ground a little bit.

It would just amaze you at the size and the complexity of it.

Think of something that's moving very slow, about 0.8 or 0.9 miles an hour,

moving this big rocket down the road. It's fun to get up

every day and come out and work on the crawler. Our universe is a wild and wonderful

place. I'm Patty Boyd and this show, NASA is your tour guide.

Rockets are what launched some of our heaviest and most far-reaching instruments into space.

But what gets these rockets to their last destination on the ground? The launch pad.

In this episode, we're exploring some of NASA's most powerful

ground machinery, the crawlers. These one-of-a-kind, six million pound behemoths are what

transport rockets and their mobile launch platforms so that they can make their ascent into space.

And the crawlers have a long history.

You almost have to go all the way back to the beginnings of NASA here at Kennedy Space Center.

That's where they built the launch vehicles.

That's the crawler's senior project manager, John Giles.

The launch vehicles he's referring to are the rockets that would help NASA send humans

to the moon for the first time.

In the early 60s, NASA built the Saturn 5 rocket to carry out the Apollo missions.

Saturn 5 was built upright and was a staggering 363 feet tall with the Apollo spacecraft on top.

That's taller than the Statue of Liberty.

And somehow, the rocket had to travel from the vehicle assembly building to the launch pad four miles away.
