[adventurous music] [squirrel coos] ♪ ♪ [squealing] - Whoo!

[all laughing] - So much fun!

- Whoo!

- I love racing these hover-scooters.

This time, I really want to win.

- [laughing] Me, too!

Wait, what's a race?

And what does "win" mean again?

- A race is when everyone tries to go as fast as they can.

And "win" means, um, to be the person that finishes the race first.

- Hmm, I kind of remember that.

You see, we don't have racing and winning on Bortron 7.

But Sunspot is the first in everything we do.

- So he always wins.

- Ah, I get it.

Well, we could try a race now, and I could try to "win."

- I like it.

Let's do it now.

On your mark-- that means line up-- get set, and go!

[energetic music] Whoo, that is one fast alien pet.

[horn honks] - Hi, kids.

I'm meeting my brother Zucchini today to fly our saucers around the planets.

- But you're not actually racing against each other?

- Race?

Nope.

We don't race.

We just try to beat our own previous time when we flew together.

We've flown around Bortron 7's moons since we were kids.

[watch chimes] - [squeaking] - No, Sunspot, it's not time for your ear massage and sushi.

- But it is time to meet Zucchini.

Say, kids, you want to join me flying around in space with old Uncle Z?

all: Yes!

- Uh, racing around the solar system?

Even faster than usual?

Whoa!

- [squeaking] - Hey, look, Sean, you're in the wagon.

- Mrs.

Propulsion, are you sure today is "meet Uncle Zucchini" day?

You might have the wrong-- - Five, four, three, two, one!

Doors are shut!

Engines on!

Everybody in their place?

Let's go into outer space!

all: Ready!

Jet!

Go!

- Oh, never.

That's an Earthie thing.

Oh, Zucchini and I always had so much fun, seeing who could drink more exploding shakes, trying to stand on each other's heads longer than we did the time before... - Ah, what a fun Bortron 7 childhood.

[horn blaring] - There's Uncle Z!

[brassy music] ♪ ♪ - Hey, hey, hey!

Good to see everyone.

Hiya, Sis.

- So, Mom, Uncle Z, I have a new, fun idea about how you can drive your saucers around today.

- New?

Fun?

My ears are listening.

- How about a race?

- Ooh, is a race sort of like a potato?

- No, a race is nothing like a potato.

You make French fries out of potatoes.

A race is when everyone tries to go as fast as they can to reach a place first.

- And the first one there wins.

- Hmm, interesting.

Though Celery and I have fun just flying our saucers and not doing that potato thing.

- A race is nothing like a potato.

A race is an Earthie contest.

You try to go faster than the other saucer.

- Hmm.

[together] Maybe.

- Maybe?

How about "yes"?

- You both like going fast, right?

It's kind of like this.

It's a Commander Cressida comic called "Solar System Showdown."

It's all about a race.

[together] Hmm.

- You know, it could be fun, Z. I say, just once, we race.

- Fine, once.

For fun.

[cheering] - Yeah!

- Let's race!

- Let's start racing!

- All right, the best racing plan is start fast, then keep at a steady pace the whole way.

- Wrong.

Slow and steady at first, then fast-fast-fast at the end.

- [chortling] You'll never win like that!

- Oh, ho, ho, yeah?

Well, we'll see.

[both squealing] [drum roll] - Hey, let's win this and show Zucchini who's, as you Earthies say, numero uno.

- Okay, here are our "Space Race" rules.

Each saucer must fly past every planet once, starting with the planet closest to the Sun.

So Mercury's first.

- Then every planet all the way to Neptune.

And you race back to the finish line: the Earth's Moon.

- Aha, and the saucer that reaches the line of finish first wins the race?

- I get it!

- Correct.

Time to race!

Newly-installed Bortronian engine boosters?

- I--I don't think we can catch Uncle Z.

- [squeaking] - [gasps] I have an idea.

In her race, Commander Cressida used a really cool trick called a gravity assist.

We could whip around the planet like Commander Cressida did, and doing that, we'd pick up a lot of speed, so we could win the race.

- Perfect, but does that really work?

- It does.

- Face 9000 ready to gravity-assist you.

[together] Hi, Face.

- Hello.

A gravity assist is when a spacecraft like your saucer flies very close by a planet and uses the planet's gravity and energy to gain power and whip around back into space a lot faster than it was going before.

The energy of the planet's gravity assists the saucer.

[together] Cool!

Thanks, Face.

- Happy to assist.

[laughing] - Well, Jupiter is the biggest planet.

So it'd probably help us the most.

- If we want to win, we better try this gravity assist now.

Uncle Zucchini is way ahead.

all: Let's do it!

Excelsior!

- Approaching Jupiter.

Come in close, Mrs.

Propulsion, but not too close.

- Wow, nice.

And now fly as straight on as you can.

We should pick up more and more speed.

And steer away from Jupiter at the exact right time.

Okay, ready?

Steer away... now!

[engine whooshing] all: Whoo-hoo!

- It worked!

Boo-yah!

Science!

It did!

It was a brilliant suggestion, Sydney.

And very good dancing, Sunspot.

Oh, yeah!

And we're about to land... [together] On the Moon!

Whoo-hoo!

[cheering] [together] Yeah!

We won!

- Oh, ho!

No.

No, I don't want the sushi, but thank you.

Today, all of us on Team Propulsion are numero uno.

- Hey, I got an idea.

How about we do another Earthie space race again in a few months?

You in, sis?

- Oh, you're on, Z.

And next time, you can win.

See you in an Earth month.

[kids cheering] - [humming] - Whoa!

What you working on, Jet?

- A time machine.

- A time machine?

- Cool!

Wait, what's a time machine?

- Uh, let's see, it's a machine that can take us forward or back in time to any time we want to go to.

- Wow, we can go back in time?

To, like, last week?

Or when I was three?

- Yup, at least that's the idea.

I haven't tested it yet.

- Oh, I've always wanted to time travel.

There are so many great stories about it.

But you know, Jet, the stories usually say that you can't change the past; you can only learn from it.

- Cool, I can't wait to learn from the past.

- Why do you want to time travel, Jet?

- Well, you know how much we Bortronians like to make mistakes?

I think it would also be great to back in time after I make the mistake and fix the things that I got wrong the first time.

- You guys, my mom just told me that a meteor shower's about to happen.

- Um, why do meteors take showers?

- Actually, it's called that 'cause it's a shower of meteors.

They kind of look like they "shower" down from the sky.

- [squeaks] - But Mindy, meteors almost always burn up in the atmosphere and don't make it to Earth.

- So how come the meteors come in "showers"?

- Well, most of the time, meteor showers happen when the Earth passes through the path of a comet, which leaves a trail of dust behind.

[all coughing] Anyway, the dust and bits of rock burn up when they rub up against the Earth's atmosphere.

- And that makes meteors?

- Right.

Even a tiny piece of rock can burn up as a huge, bright meteor.

all: Ooh.

- Wow, I can't wait to take a meteor shower.

- Whoa, what's that you're working on, Jet?

- Ha, I thought you'd never ask.

[together] A time machine!

- Oh, okay.

I--wait, a time machine?

- Uh-huh.

- Come on, Jet.

You don't actually think you're gonna travel in time, do you?

- Well, not just me.

It's a four-seater.

All of us can time travel together.

- [sighs] No one has ever traveled in time that we know of.

It just sounds like science fiction to me.

- Well, Sean, since Jet comes from Bortron 7, a lot of his technology seems like science fiction, like how it takes us Earthies nine years to fly to Pluto, and Jet's mom can get us there in nine minutes.

- Yeah, but-- - All I'm saying is, science fiction can sometimes become science fact.

- But a time machine Jet built in his backyard?

Come on.

- [grunting] There, I'm actually ready to test it right now.

How far back in time do you want to go?

- Well, I'd want to meet my hero, Neil Armstrong, and watch him fly Apollo 11 and land on the moon, obviously.

- I'd rather go into the future than the past.

I want to live like Commander Cressida in a time where all my science fiction dreams have become a reality, like time travel.

- I want to go back and find that lost hat that I made for Stuffy Bear.

- Well, I want to go back to last Saturday for another slice of that amazing pie I had for dessert.

I forgot to ask for seconds.

How could I have been so foolish?

- [grunting] - Jet, let's at least be scientific about this.

- [sighs] You're right, Sean.

I should go back in time to the moment pie was invented.

- Sounds like fun.

- Ha!

I know, right?

- Ugh.

You guys-- [thunk] - [muffled groaning] - [squeaks] [stretching] - [muffled groaning] [pop] Whew!

Shoom!

Beyoom!

Byom, byom!

Pow!

[together] Aww.

- Maybe Sunspot got a picture of it.

- [squeaks] - Rats--all this talk about meteor showers, and we missed the best meteor.

- Wait a minute.

This is the perfect opportunity to test my new time machine.

- Huh?

- I can simply program it to take us back in time to just before that big meteor happened, and we'll all be ready to see it, instead of whatever else we were doing.

- And also, we can find out how the vase ended up on my head.

- Heh, yeah, that too.

I'll set the time-travel time back just three minutes.

The meteor shower happened with the last three minutes.

It's the perfect amount of time travel for a first experiment.

[grunts] Hop on, everybody.
