Our planet is unique.

An extraordinary piece of engineering, over four and a half billion years old.

And to see how it works, we've created something rather special.

We've collected the latest information from scientists around the world.

We've added satellite maps, sonar and radar images and we've brought it all together to make this.

We've created a virtual planet earth.

And in here we can look at the machinery of the earth.

We'll see how an enormous energy source, buried thousands of miles within the planet, shapes our world, up here on the surface.

I'm going round the world to see this machine in action.

This is mission control, can you hear me?
