- [Jared] In this video, I want to show you

We'll look at all the preparation beforehand,

and then their 8 1/2-minute journey into space.

I'll show you more about this after the video.

However, I think it's still really important to learn about.

In preparation for this video, I read a few books.

and it was written by three-time astronaut Mike Mullane.

what it was like to ride on the space shuttle.

I reached out to Mike, and he was really helpful.

Though before we get too far, let's review.

and carries the astronauts and payloads into space.

I have a video all about the inside of the Orbiter Vehicle.

I'll put a link in the video description down below.

That's what the orange external tank is for.

Even this isn't enough to launch us into space.

These are called the Solid Rocket Boosters or SRBs.

It takes a lot of work to get all of these pieces

There were two launch sites for the space shuttle,

and Vandenberg Air Force Base in California.

Shuttle launches from the Vandenberg site ended up

shuttle missions were launched out of Florida.

Shuttle missions were launched from both of these pads.

about five kilometers away from the pads.

The large one here is the Vehicle Assembly Building or VAB.

This is where they would assemble the space shuttle

This building is called the Orbiter Processing Facility,

or OPF, and actually there were three OPF buildings.

It's where the orbiter was serviced in between missions.

Over here is the Shuttle Landing Facility.

This is where a mission ends for the space shuttle.

Sometimes due to weather or other circumstances,

When this happened, we need to get the Orbiter Vehicle

and the shuttle can't really take off again

The Orbiter Vehicle was taken to the Mate-Demate Device,

and then load it on the back of a special airplane

It was then flown across the United States

to get back to Kennedy Space Center in Florida.

Once inside, the engineers would literally crawl

all over it to fix or replace many of the shuttle components

This process can take several months to complete.

Meanwhile, work starts over here at the VAB.

Once ignition starts at liftoff, it cannot be turned off.

Now it's time to lift the external tank into place.

One for liquid hydrogen, and one for liquid oxygen.

until just a few hours before the launch.

Now at room temperature, hydrogen and oxygen are both gases

which take up an enormous amount of space.

But if we put them at extremely cold temperatures,

and we can put a lot more fuel inside of the tanks.
