Audrey, good to see you!

Hi!

Hello!

What are you doing out there?

I was just fixing a few things around the old space station.

Would you like to join me on my space walk?

(Gasping) NICK AND SALLY: Yes, please!

But when I say "space walk," I really mean flo-o-o-oat!

(Nick giggling) Floating's fun!

Sure is!

(Suit chiming) Please remember to wear your space helmets at all times for your protection.

Thanks so much.

(Giggling) Whoa!

Do we live down there?

ASTRONAUT AUDREY: Roger that!

That's a big "yes, sirree"!

But back home, it looks flat!

From up here, it's round like our ball!

That's Earth!

And all that blue is the swirly-whirly ocean.

CAT IN THE HAT: Why not take a look through my space zooma-rooma?

You can see lots of places, like Zooma-Booma.

You can see Splishy Splash Splosh, and Wallamaroo.

And if you look close, you can see your house too!

NICK: Hi, Sally's house!

(Sally giggling) SALLY: Hi, Nick's house!

That's funny!

One side of the Earth's lit up, and the other side's dark!

Huh?

Hey, you're right!

The dark side looks like night-time, and the light side looks like daytime!

How can it be daytime and night-time at the same time?

That's a great question!

Follow me inside my space station, and I'll try the answer.

Welcome to my space station!

I hope no one's afraid of the dark, because to understand night and day, we need to turn down the lights!

Nighty night!

Now, what do you need to make it daytime?

I know!

An alarm clock, wakey wakey!

(Alarm ringing) Oh!
