SHE MIMICS SPACESHIP

Safe landing! Oh, hello there.

I'm just playing with my space rocket and, look,

Mr Astronaut is about to walk on the moon. Whoosh!

MIMICS SCI-FI DEEP SPACE ECHOES

Oh, I'd love to go to the moon.

-BEEPS

-Oh!

I hear a beep. I see a flash. I wonder what they're going to ask.

-Hi.

-Hi, Nina.

-Hi.

-We've got a question for you.

How do space rockets work?

That's a great question. How do space rockets work?

It's exciting when rockets go into space

and take astronauts there. How do they work?

Why don't you come down to my workshop and we'll investigate?

-BOTH:

-See you soon, Nina. Bye!

-Bye.

I'm going to need some help to answer this

and I know just who to ask. OK, neurons, time to get to work.

-ALL:

-Neurons at the ready.

OK, today's question is how do space rockets work?

Which neuron will be most useful in helping us find the answer?

-ALL:

-Me!

Will it be fabulous Felix?

I can help so very much if you need the sense of touch.

-Will it be beautiful Belle?

-I send messages to brain from ear.

If there's a sound, I'll help you hear.

Will it be lovely Luke?

For looking or seeing, day or night,

I'll help you with your sense of sight.

Will it be awesome Ollie?

If it's pongy or whiffy, but you can't tell,

my messages help your sense of smell.

Or will it be baby Bud?

Sour, salty, bitter or sweet,

I'm your taste buddy whenever you eat.

-It's Belle.

-CHEERING

-ALL:

-Go, Belle! Go, Belle! Go, Belle!

Brilliant. I'm all ears, Nina.

Today's question is how do space rockets work?

Space rockets make a huge noise when they blast off,

so we need Belle, our hearing neuron, to help us today.

Stand by, neurons, I may need help from all of you.

I need to get the workshop ready before the explorers arrive.

Hamna loves her dad and Suleiman loves cricket,

but they both want to know - how do space rockets work?

It's exciting to see rockets blast off.

I would like to go into space in a rocket.

So today, for one day only, Hamna and Suleiman become the explorers!

-Hi guys,

-BOTH:

-Hi, Nina!

Welcome to my workshop and thank you for your great question -

how do space rockets work?

To find out the answer, let's start by using our senses.

-ALL:

-Woo-hoo! A senses experiment. We're ready, Nina.

So, what is a space rocket for?

Going up into space.

Yes, going up, and it's up very, very high indeed.

Even higher than aeroplanes?

That's right, Ollie, it's much, much higher than aeroplanes go.

And because it's so high, we need a space rocket to get there.

The rocket has to travel very far,

high up above the Earth to get into space.

So, let's watch a rocket taking off.

What do you see, explorers?

There's fire coming out of the bottom.

Yes, it does look like fire is coming out of the bottom,

but it isn't really, it's gas whooshing out of the rocket.

It's a bit like this balloon.

-Now, what do you think is inside this balloon?

-Air.

Yes, you're right, and air is a gas.

So, let's see what happens when we let some out.

Can you hold your hand out for me?

BALLOON SQUEAKS

Whoo!

-Whoo!

-Whoosh!

Now, what did you feel, explorers?

Air on my hand.

Yes, air pushes out of the balloon,

and the same thing happens in a space rocket.

The gas pushes out of the bottom and makes the rocket go up into the air.

Let's see if we can use balloons to make air rockets. This way!

These balloons are full of normal air,

so what do you think will happen when we take the pegs off?

-They will go up.

-Well, let's see.

OK. Five, four, three, two, one.

-Blast off!

-Yeah!

-Yay!

-They both went up!

Whoosh! Zoom! Way-hey-hey!

-It was a big whoosh, wasn't it? And what made that noise?

-The air.

Yes, and it pushed the balloon all the way up.

Real space rockets don't use air.

It's another gas that pushes out of the bottom

and makes the rocket go up into the air. Whoosh!

-OLLIE:

-The gas came whooshing out of the balloons and made them

go up in the air.

FELIX: And space rockets work by gas whooshing out of them, too.

But, Nina, space rockets are really big.

Won't they need a lot of gas?

You're right, Felix, real ones are huge

and I don't think we've got the room for a real space rocket in here.

We need to go somewhere with a lot more space.

-BELLE:

-Nina said we're going somewhere with a lot more space.

BUD: We must be going to the moon! That's in space. Whoo-hoo!

We're astronauts.

That would be amazing. Ha-ha-ha! Do you think we'll go in a rocket?

-ALL:

-Ooh!

This is the National Space Centre in Leicester

and it's full of exciting space things. Look at this.

-Two real rockets.

-They're really, really big.

I know. And guess what?

We get to go all the way up there

to see for ourselves just how huge they are.

-LUKE:

-Whoa! It's so big, I can't even see it all at once.

Let's go, explorers.

Rocket!

There's the top!

-Look how high we are. What do you think, explorers?

-It's amazing.

-What's inside the rocket, Nina?

-Come with me and I'll show you.

This is what it's like inside for the astronauts.

Astronauts are the people who control the rocket,

like a pilot in an airplane or a driver in a car.

And this is where they sit for the long journey into space.

-Oh, it's tiny, isn't it?

-BOTH:

-Yes.

Let's see if we can squeeze ourselves inside, come on. Ho-ho-ho!

Oh, one at a time. Ooh, here we go. Ooh-ho-ho!

-Oh, it's not very comfortable, is it?

-Uh-uh.

-No.

The astronauts must have been really

squashed in here during their flight.

Why didn't they have more room?

Space rockets are huge.

Well, there's a very important reason for that.

Let's climb out and I'll explain.

Do you remember earlier we found out how rockets get into space?

Gas! I remember. The gas whooshes out.

That's right, Belle, the gas whooshes out the bottom

and pushes the rocket up into the air.

But to make the gas whoosh out, the rocket needs to burn fuel.

-ALL:

-Fuel!

-A car burns fuel, like petrol or diesel,

to make it go, and a rocket burns rocket fuel

to make the gas whoosh out of the bottom

and push the rocket up into the air.

It must take a lot of fuel to get all the way into space.

It does, Ollie, that's what takes up all this space.

Do you remember the launch that we watched?

Well, rockets go really, really fast, so I think we need to do

another experiment to find out how rockets go so fast.

Let's go, explorers.

Now, here we have a water spray. Let me just check it works.

Oh! Oh, I don't want to get you wet!

Now, have you ever noticed the twiddly bit on the end of a spray?

It's got two different holes -

one's wide and there's a smaller, narrow one.

So I'm going to make sure it's on the wide one.

And can I ask you to hold your hands out? One hand.

That's it, one hand. Ooh!

-How did that feel?

-Soft.

Yeah. The water spreads out like a mist.

So now, let me just change the setting to the small hole.

Can you put your hands out again? Here we go.

-How did that feel that time?

-It's harder.

-Yes.

The small hole makes the water come out in a narrow jet

and it feels harder,

and that's just like a rocket.

The smaller the hole the gas comes out of,

the harder the push.

-And a hard push makes a rocket go...

-BOTH:

-Fast!

-Exactly.

Now, explorers, come this way.

-This is Russ, the rocket expert.

-BOTH:

-Hi, Russ.

-Hi.

And Russ is going to launch a real rocket for us.

It's a small one because it's not going all the way to space,

but it's just like the big ones at the Space Centre.

And we're behind the safety barrier here,

just to make sure we're a safe distance away.

Russ, the rocket man, has special training.

-Ready, Nina?

-Yes!

-Shall we start the countdown?

-ALL:

-Five, four, three, two, one.

-It's so high!

-Ha-ha!

Wow! Look at that.

A small hole gave it a really strong push up in the air.

And it goes super fast. Wey-hey! Zoom!

That was fantastic. Rockets are brilliant, aren't they?

-BOTH:

-Yes!

-Thanks, Russ.

# Nina and the neurons. #

So, your question was - how do space rockets work?

And I think we've answered it.

When the gas whooshes out of the balloon,

or the bottom of a rocket, it goes up in the air. Whoosh!

It was so exciting to see the real space rockets.

They need a lot of space for fuel.

All that fuel gives the rocket a super big push to take it high,

high up into space. Zoom! Whoo-hoo!

I loved feeling the water. The squirty bottles were fun.

And that was why the rocket that Russ launched went so fast.

I loved seeing the rocket go zooming up.

So, I hope that's answered your question.

-BOTH:

-Thanks, Nina. Bye!

You're welcome. Bye.

If you want to know more about the science that's all around us,

go to the Nina section on the CBeebies website. Have fun.
