The first two parts of the shuttle assembled inside the Vehicle Assembly Building are the solid rocket boosters and the external fuel tank. The rocket boosters are shipped to the Kennedy Space Centre in sections and must be assembled and bolted to the mobile launch platform. They will serve to hold everything together until launch.
The external fuel tank, the only disposable section of the shuttle, is shipped by barge and stored in one of the bays of the VAB. When ready, it is attached to the solid rocket boosters. The final step in the assembling process is attaching the orbiter.

When I first saw that thing in some movie it was mindboggling. That crawler is absolutely massive! And how it is actually capable of moving the shuttle into position amazes me. Whats most amazing is how they can use a crane to lift the space shuttle into position. It always amazed me what kinds of stuff NASA came up with.

When I was on a trip to KSC in the early '90s I saw the crawler. Up close and personal from about 50 feet away. There is a long gravel roadway leading from the assembly building to the pad. This thing moves like 3mph. It was on it's way back from the pad so it was empty but still it was damn impressive, especially the huge electric motors that drive it. I doubt if you can get anywhere near as close nowdays though.
