but then landed like an airplane on a runway.

In this video we're going to take a closeup look

We'll see the crew compartment, the payload bay

and all the way to the engines on the very back.

I'll leave links for these videos down below.

But I think it's about time that we finally take a look

Thanks to our sponsor for this video which is Brilliant,

The space shuttle was used by NASA for 30 years

2011 was the last time the space shuttle was flown.

The space shuttle consists of the orbiter vehicle,

and then the two white solid rocket boosters

The external tank is basically a big fuel container

The orbiter and the two SRBs are reusable,

They had to make a new one for each mission.

Keep in mind that a lot of people call this part

the space shuttle even though technically

this is just one part of the space shuttle.

Sometimes these terms are used interchangeably.

Let me show you what a typical mission looked like.

The two SRBs did most of the work for the first two minutes.

where they would be recovered and used for a future mission.

After that the orange external tank was separated

The three main engines are now dead weight

and won't be used for the remainder of the mission.

Now the shuttle will circle the earth once every 90 minutes.

That's a speed of 28,000 kilometers per hour.

The payload bay doors will be opened once they are in space.

the orbiter will be facing backwards as it orbits the earth.

This protects the astronauts in case of any space debris.

Many of the missions were around 320 kilometers high,

but some missions went as high as 550 kilometers.

Anywhere in this area is called low earth orbit

and it's where all of the shuttle missions happened.

the OMS motor fires up to slow the spacecraft down.

and things are going to get a little hot.

and the orbiter lands similar to an airplane.

This red parachute helps to slow it down on the runway.

launch vehicles were only designed to be used once.

You had to build a new one for each mission,

the orbiter vehicle could be reused for many missions.

There were five of them built to travel into space:

Columbia, Challenger, Discovery, Atlantis, and Endeavour.

And actually there was another one called Enterprise.

but it was only used for tests here on earth.

Challenger and Columbia were both destroyed in accidents,

but the other four orbiters can be found in museums

the most complex flying machine ever built.

On most missions it had a crew of seven astronauts
