Welcome aboard NASA tours, my name is George Herman.
We'd like to bid you a warm welcome to the John F. Kennedy Space Center.
During our tour today, we'll have recorded
commentary and at times, I'll stop the tape to answer any questions
you might have.
For those of you with a camera,
anything you see you may photograph.
Now smoking is not permitted on our bus so
let's just settle back and relax,
and we'll begin our trip with the Western
world's first spaceport.
[Bus engine noise]
Cape Kennedy, formerly called Cape Canaveral,
was selected as the site for testing ballistic missiles, and
later as our nation's first spaceport.
As our space program grew, the site was extended to include Merritt Island.
One of the reasons this was an ideal site,
is that the first stage of a rocket doesn't go high enough to go into orbit.
And when it falls back to earth we'd rather
it fall back in the ocean,
than over inhabited areas.
Another reason is from this point,
we can take advantage of the Earth's rotation
and achieving orbit and also the islands stretching
southeastern from the Cape were a ready-made
chain of stations for our tracking network.
Here at Merritt Island, there are more than
88,000 acres of land.
And what's three thousand acres are orange groves and
39,000 acres have been left as wildlife preserves.
[plane engine noise]
We have wild boar, armadillos, alligators,
thirteen bald eagles nests, and more than 200 separate species of birds.
And even one reporting of a panther.
[Bus engine]
The long white building on the right is a
manned spacecraft operations building.
Here is where we receive and check out the
Apollo spacecraft and lunar modules, and if you ladies think you keep your house clean,
(chuckles), well you should see the inside of this building.
The walls, the ceiling, and even the floor
is painted white and they never stop vacuum sweeping.
[background noise]
If you're just entering the room you can wear
regular clothes.
But before you can go near one of the spacecraft
you have to put on white gloves, and a special lint-free gown,
like a surgeon would wear in an operating room.
[cleaning machine sounds]
They even wash the air that goes inside the
spacecraft.
-First Male: 97.2 microns.
-Second Male: Okay good.
[distant chatter]
-Narrator: In other buildings, assembled scientific
communication and weather satellites, and the Surveyor spacecraft.
For you folks who don't know what a Surveyor
is, that's an unmanned vehicle, and we've already soft landed five on the moon.
You've seen the pictures they send back.
The last two even had claws which dug at the
surface,
scooped up the soil, and then sent a message
back to earth to tell what kind of soil it was.
One reason for all of this, is to make sure
when our astronauts get to the moon,
they've got a pretty good idea of what to
expect.
While all of this is going on, the astronauts
are practicing every detail of the flight.
To help them do this they have a trainer that
is just like a real spacecraft, where they can simulate everything from the actual blast-off,
complete with sound effects, to a docking
in space.
[Ambient electronic sounds and voices of NASA engineers and astronauts]
[Voices of NASA engineers and astronauts] Roger.
[Ambient electronic sounds]
Roger.
Five-four-three-two-one
I have lift off. The clock has started.
[engine sound]
-Roll commence. -Roger.
-Roll complete. -Roger.
Say again?
No strain. Let her go.
-Rate change. -Roger-rate change and we're venting.
Pressure's decreasing.
One minute.
RCS Command module -propellant on.
Roger switching.
[bus engine]
How far do you think that building is? Anyone like to take a guess?
-Female: One mile?
-Narrator: Anybody else?
-Male: Closer to two miles. -2nd Female: A mile and a half?
-Narrator: That's the Vehicle Assembly Building and from
here, it's five miles away.
[Bus engine sounds]
Now we're going inside and have a brief rundown
on what takes place inside the building.
The size of this structure folks is again
deceptive because we don't have much on our flat terrain to which we can compare it.
The best way I know to get the full impression
of its height, is once you get off of this bus,
get your feet firmly planted on the ground,
just lean your head back, and look straight up.
Every once in a while, we'll have someone
from New York to remind us that the Empire State Building
is just a little bit taller than this.
This we have no quarrel with.
The Empire State Building about two times
as high.
However if we cut the Empire State Building
up, we could get nearly four and a half Empire State Buildings
in the walls of this one.
-Female: How much did it cost?
-Narrator: One hundred and sixty million dollars, ma'am.
The Saturn Five rockets you see in this building
are not manufactured here.
They're made many different parts of the country,
California, Louisiana, Alabama and
brought here by barge and some of the biggest
cargo airplanes in the world.
Now that you've seen the size of some of our
rockets,
you can understand why we must have a big
building to put them together.
Four rockets, each 36 stories tall, can be
assembled here at one time.
When this building was under construction,
clouds actually formed under the roof and it rained inside.
The giant fans have been installed, that keep
the air moving so this can't happen.
Once all the individual stages are checked
out they're moved into place with an overhead crane.
The Apollo Saturn rocket consists of five
sections,
each stacked on top of the other, the main
booster, the intermediate stages, and finally the payload that contains a
spacecraft that will orbit the Moon and a
lunar module.
It will take two men down to the surface and
then bring them back again.
[Music]
When the rocket is assembled and all the systems checked out again,
they open the doors at the side of the building.
The doors are made up of sliding panels each
panel weighing 30 tons, and it takes 45 minutes to get them open.
[Music]
A large crawler-transporter, which is like a giant tractor,
is driven into the building, and lifts the
rocket platform and all, to take it out to the launch pad.
And they usually start early in the morning
because it takes all day to get there.
[Music]
It's over a half a million miles to the moon and back.
The first three miles of that trip is made
right here on the road out to the launch pad.
[Music]
The road out to the launch pad isn't a divided
highway, but two road beds filled with loose rock to help cushion the weight.
When the crawler-transporter is carrying the
mobile platform with the Saturn rocket,
there is a total of 18 million pounds moving
along at a top speed, of
one mile an hour.
When the crawler is empty it can really scratch off.
It can double its speed and go 2 miles an hour.
[Engine and driving noise]
We had two gentleman from Texas out here the
other day, and one of them looked at those crawler-transporters and said,
"Hey, Tall, we get back to the Big D"--for
you folks who don't know what the Big D is, that Dallas--
"Remind me to buy one of those things."
And the other said, "What in the world would you do one of those?"
And he said, "I'd put a blade on it and mow my lawn."
[Music]
[Music]
[Bus engine]
Our Saturn 5 rocket, when is completely assembled,
stands 364 feet tall, weighs
6.2 million pounds, and most of that weight
is fuel.
When this rocket leaves here, it will lift
off with the thrust of more than seven and a half million pounds.
This is about 180 million horsepower.
That's more horsepower in a string of cars
lined bumper-to-bumper from here to Seattle, Washington.
[background chatter]
Now from here, you can get a good view of
the roadway going up the top of the launchpad.
Remember that crawler-transporter must traverse
this grade with the Saturn V rocket.
There are automatic leveling devices to keep
the rocket level, so it doesn't become top-heavy and fall over.
[Engine noise]
We're test launching these rockets right now
in preparation for a launch to the moon.
But it's more than a moon rocket folks.
It would do that job and whatever else this
country needs to do in space for a long time to come.
-[Man 1] Okay-are there any changes to the schedule? Arnie?
-[Man 2] Line item seven,
which is shown for all day, all of first shift
Tuesday, the tank pressurization test,
will not start until
1300.
-[Man 3] When do you want to run leak check?
-[Man 2] First shift Tuesday.
-[Man 4] Arnie, you're gonna extend that time out for
five hours by cutting it off in the front end of that
LH2 storage tanks pressurization?
-[Man 2] Negative--the hazardous portion of that test
should last only about four hours, Ted.
-[Radio communication] Time check coming up on Apollo Saturn count. T-minus 8 hours.
[Ambient sounds of control room and voices of NASA engineers]
[Music]
[Sounds of traffic]
[Music]
-[Man] We're now beginning to pressurize the tanks
within the Saturn 5 vehicle.
We'll pressurize all of the tanks in all three stages
with gaseous helium.
As the pressurization builds up it's being
monitored here in the the Control Center.
Now at 1 minute and 40 seconds and counting.
- [Person on radio] 1-30.
-Our status board still indicating all is well.
Status board shows instruments units, spacecraft, and all the launch suppport operations, well
at this time, at 90 seconds and counting.
Houston flight now confirms that they are-
that they are go for the flight as are all other aspects of the mission.
T-minus 1 minute 16 seconds and counting.
The pressurization
continuing within the vehicle at this time.
We also have a hydraulic commit that will
permit the hydraulics to drive the engines in the first stage.
Liquid hydrogen tank in the second stage now
pressurizing.
T-minus 60 seconds and counting.
Our status board still shows we're go at this time.
T-minus 50 seconds and counting.
We have transferred to internal power--the transfer is satisfactory.
6.2 million pound Saturn Five launch vehicle
now on its own power at 38 seconds and counting.
