[upbeat music] ♪ ♪ - [panting] Hey, it's the hottest day of your Earth summer.

What are you all doing out here in the sun?

- Making money.

- Making what?

- We're raising money for Sean!

He's got a new cause.

- I just read that if we want to send a human mission to Mars and return the astronauts safely to Earth, it's gonna cost $5 billion.

- Is $5 billion a lot of-- uh, what do you call it-- "money"?

- Oh, yeah, it's a lot.

So I want to do my part and get the mission off the ground.

We got to go to Mars!

- But if you really want to go to Mars, you can just ask my mom and dad, and they'll fly you up there in the saucer in five minutes.

- Jet, I want to grow up to be an astronaut, to train really hard, and then get picked to lead the team that flies to Mars.

The Earth way, in a rocket!

- Which is way slower than the Interstellar Overdrive that you Bortronians have, Jet.

- And don't Earth rockets cost a lot of money?

- Don't worry about that.

I've got a foolproof plan.

- How are you gonna raise all that money?

- By selling snow cones.

If I sell 'em for 50¢ each, I figure I'll need to sell 10 billion of 'em.

- Or one really, really expensive one.

- I love this idea!

What a great plan.

And what a great Earth invention.

You can make snow cones in so many different colors!

- Mm-hmm.

The rainbow ones are the best.

- Okay.

Ready for our first customer.

It's so hot out, we should sell a ton of 'em.

[crickets chirping] - Okay.

Where are the customers?

- Well, so far, we've got Sunspot.

Hey, enough free samples.

Your next one's 50¢.

I'm trying to get to Mars.

- [chirps] - Thank you.

- Hmm.

Sean, the ice in the machine is starting to melt.

We better get some more.

- Okay, I'll go home and get some from my freezer.

Hey, would one of you please sit here and mind the store while I'm gone?

- Ooh, ooh!

Me, me, me!

Can I help?

Can I do it?

Can I?

I'm right here!

- Great.

Thanks, Mindy.

I'll be right back.

- Yay!

Hey!

Get your snow cones right here!

Hottest day of the year, and we've got a red-hot sale on snow cones.

Just 50¢.

- Hi, Dr. Sean's Mom!

- Only 50¢?

That's a bargain.

- And it's for a good cause.

We're helping send a mission to Mars.

Only 50¢.

These icy treats are even colder than the ice-popcakes from the frozen star system of Marzipan!

- [whispering] Jet, most Earthies have never heard of the ice-popcakes of Marzipan.

- [whispering] That's good.

I doubt if these snow cones really are as good as the ice-popcakes of Marzipan.

Would you like a Commander Cressida snow cone and help send Sean to Mars?

- You mean the kid who keeps kicking his ball in my yard?

I'll get three.

- Well, here's the last of the ice from my freezer.

- That'll be 50¢.

Thank you.

You guys, we need ice.

Look at this line.

And it's not getting any cooler out here.

- We're facing a serious ice shortage, Sean.

What are we gonna do?

- Hey!

I know a place where we can get as much ice as we want!

- You mean the supermarket?

- [laughs] Yeah, sure.

We could go get regular Earth ice, but if you want the most special, unique, out-of-this-world ice, you don't get it from the supermarket.

- Wait a minute.

I think I know where this is going.

- [gasps] You sure do, Sean.

We can get all the ice we need from Enceladus.

- Enceladus?

What's that?

Actually, I'm afraid to ask.

- Enceladus is one of Saturn's moons.

It's made of ice.

Hop in!

- But do we really have to go that far for ice?

- It's not that far.

With Interstellar Overdrive, we'll be there in a few Earth minutes!

- Is there a lot of ice on Enceladus?

- Tons of it!

Just shooting into space, waiting to be scooped up.

- Perhaps I can help explain, Celery.

Take a look.

This little moon of Saturn may look like a solid ice ball, but only the outside is frozen.

Below the surface is a liquid ocean.

all: Ooh.

- As the ocean underneath moves, it cracks the icy surface.

When that happens, boom!

A geyser of water shoots out into space.

all: Wow!

- And since space is freezing cold, the water immediately turns to ice.

Some of that ice falls back as snow onto Enceladus' surface, but the rest escapes into space.

- Where does it go from there?

- Excellent question, Sydney.

That ice is most of the material making one of Saturn's rings.

So you can see that the ice-making process of this little moon of Saturn is slowly helping to form even more rings around the planet.

all: Cool!

- Wow, a moon of Saturn is actually making more of Saturn's rings?

That's incredible!

- No kidding.

- Space is amazing.

Where's that ice?

I'm almost out.

And it's really hot, and I'm trying to entertain this crowd, but it's getting ugly.

- Don't worry, Mindy.

We'll be at Enceladus soon.

We're almost there.

Good.

Hurry up!

Here's Enceladus.

- And look!

Now it's shooting out of a crack!

all: A geyser!

- Now we just fly through the geyser and scoop up all the ice we want.

- Okay, but who's gonna scoop up the ice?

- Oh, I know.

Why don't we just draw straws?

- No, thanks, I always pick the short straw.

- But what exactly does "draw straws" mean?

- Whoever picks the shortest straw goes.

- Cool!

I love this drawing of straws.

We've got enough ice to make a lot of snow cones.

Maybe not enough to make 5 billion... - [laughs] Yeah.

If you want to sell $5 billion worth, we may have to go back to Enceladus a few times.

How much Earth money do we have so far?

- Hmmm, $27.50.

And a marble.

- [laughs] - [giggles] - So did you make enough money to go to Mars?

- [sighs] Not really, Mom.

Rockets cost a lot.

- Well, it's enough to make a nice donation to our science museum.

They have great educational programs about Mars.

- Yeah, 'cause we need to learn a lot if we're gonna figure out how to make that Mars mission work.

Sean and Sydney are walking into the garage.

Oh, things are heating up on this case.

I know Jet's been working on something for the past few days.

That Jet Propulsion character is up to something.

What's he building in there?

- Whatcha doing, Mitchell?

- Ah!

Mindy?

Don't sneak up on me like that!

- Well, you're the detective.

You should know all about sneaking up on people.

So what are you up to?

Spying on Jet?

- No.

Um, well, yes.

I'm working on a case.

I call it, "What's he building in there?"

I'm on a stakeout watching Jet's garage to see if I can figure it out.

- Why don't you just go over to Jet's garage and ask?

- Because I'm a detective.

I prefer to figure stuff out for myself.

That's what detectives do.

- Okay.

I'll be in Jet's garage if you need me.

Whoa!

A flying saucer.

So that's what you're building in here.

- Yep, I wanted to make one of my own.

- Isn't it cool?

- Yeah.

How many people can you fit in it?

All of us?

- It's a one-seater, just big enough for little trips around the neighborhood.

- But can you take it into space if you wanted to?

- [chirps] - No, it's not like my parents' wagon or anything.

That saucer has Interstellar Overdrive.

This one's more of a flying-- what's the Earthie word for it-- go-kart.

- Okay, Mitchell's out there behind the bushes, wondering what you were up to.

[together] He is?

- Why doesn't he just come in and see for himself?

- I guess he thinks it's more fun to watch through his binoculars from behind the bushes.

It's what detectives do.

- Well, I'll be finished soon, and Mitchell can watch us when I test it out!

- Uh, Jet, it's better if you don't show your flying saucer to Mitchell.

- Why not?

- Well, Sean and I are used to you by now.

- But some people just won't understand how a kid can build their own flying saucer in their garage.

Flying saucers are usually built by space aliens.

- [chirps] - And you need to keep your space alien identity a secret.

- Ah, right.

Alien identity a secret.

Hi, I'm just a normal Earth kid.

- Yeah, we'll work on that.

[jet engines humming] - 5:47.

The weird lights are going on and off again.

Ah!

Mindy!

- I went over and looked.

Jet's just building a flying saucer.

- A flying saucer?

Cody, this case just broke wide open!

- So this saucer will really fly?

- It should.

I want it to have lots of power, so I installed some pretty powerful Bortronian thrusters.

See, for my saucer to fly, it's gonna have to beat gravity.

And Earth has some very strong gravity.

- I always thought our gravity was kind of normal.

- Well, naturally, for an Earthie, it's normal.

But Bortron 7 is smaller than Earth, so our gravity is weaker.

- What's gravity again?

- It's the force that makes our feet stick to the ground.

- Or gum does that.

- [laughs] True.

Gravity is the thing that makes us come back down when we jump up.

- What makes gravity work?

- Hmm, that's a good one.

How does gravity work?

Let's ask Face!

- Hello, Jet!

Has gravity got you down?

- Yeah, it's a drag.

Jet, zero.
