[funky music] ♪ ♪ - Wow, our very own machine that turns lemons into lemonade!

- Jet, don't you think there's an easier way to get lemons?

- Probably, but this is the fun way!

[slurps] Mmm, sweet, yet sour.

Ha, I love it!

- Yep, when life gives you lemons, make lemonade.

That's what my mom always says.

- Is that why we're selling cups of it from this lemonade stand?

- Actually, we're selling lemonade to raise money for our rocket to Mars.

- But don't rockets cost a lot of Earth dollars?

- Billions of dollars, actually.

- How much do we have so far?

- $3.79.

- Every little bit helps.

I want to be selected to lead the first crew of astronauts to Mars.

And I figure it would help if I already owned a rocket.

- Wow, you really want to grow up to be an astronaut, huh, Sean?

- I sure do.

And that's why I need to do a lot of training.

You have to be fit, and know a lot about science and math.

Look, I made a chart.

See, running, swimming, chin-ups, and push-ups.

- Wow, that's a lot of running and swimming and stuff.

- It is.

I'm also working on math while I run.

Sunspot's going to help, watch.

[panting] 6 plus 12 is 18.

- That's so cool, Sean!

- [whistle blows] - Well, got to get back to my training.

Do you mind running the lemonade stand while Sunspot and I run through the woods?

- Yes, I'm finally in charge of my own small business.

Whoo-hoo!

- We'll be fine.

- [whistle blowing] - 2 plus 17 is 19.

- [whistle blowing] - 11 plus 5 is 16.

- [whistle blowing] - 28 minus 4, [grunts], is 24.

13 minus 7 is 6.

[coffee pot gurgling] - Okay, how much time do we have?

- Until the coffee's ready?

- No, until the director of NASA's Johnson Space Center gets here.

both: Dr. Ellen Ochoa!

- Meanwhile, let's get our presentation together.

- Right, she's coming today to review our design of a component for the Orion spacecraft that will take humans to the Moon, the asteroids, and Mars.

- And since we're talking Mars, I thought I'd program our Mars rover to make some cool moves, hmm?

[beeping] Ready, Beep?

Go!

- Ow, my foot!

- Ooh, okay.

Let's focus.

We still have one problem.

Our design doesn't work yet.

- And we're almost out of time!

- Two problems!

- Three problems.

Ellen Ochoa is coming!

[phone beeps] - Ellen Ochoa speaking.

Oh, hi, Isidro.

I'm driving to the DSA to meet with Dr. Skelly, Rafferty, and Bergs.

Yeah, it's nice to be back in Boxwood Terrace.

[Floyd chittering] Even the squirrels are friendly here.

I've got some time before my meeting.

I'm just going to park and walk around.

Bye!

- [panting] - [whistle blowing] - 9 plus 27 is 36.

- Such a charming place.

What's next, kids with a lemonade stand?

- Lemonade, get your lemonade right here.

Only 50 cents.

- Homemade lemonade, huh?

- Yes, ma'am.

Thanks, it's for a really good cause.

- Oh, what's the cause?

- Sean wants to buy a rocket to go to Mars.

- Really?

- Wow, hey, I just happened to be on planet Earth.

I might as well stop and buy some of this amazingly delicious-looking lemonade.

- [laughs] Sure, here you go, sir.

- Ah, thanks, you can call me Carrot.

- Carrot.

What an interesting name.

I'm Ellen.

- Oh, hi, Ellen.

Also an interesting name.

- Wow, I love this lemonade maker.

Who built this?

- We all did in my garage.

- I'm impressed with your engineering skills.

So you're interested in space?

- Actually, I'm from space.

I've been to Mars several times.

- Jet means that we play games about going to Mars.

- What fantastic imaginations.

- I agree.

I've gone along to Mars with them.

My wife usually drives though.

- That's...wonderful.

Do you ever look at Mars through a telescope?

- Yeah, we look at it from our treehouse observatory.

- You have a treehouse observatory?

- It's also a treehouse space station.

- Wow.

- It's also a tree-house!

What a crazy Earthie invention.

A house in a tree!

We don't have those on Bortron 7.

- [nervous laughter] - [laughs] Wait, why am I laughing?

- So where is this treehouse observatory space station?

- It's right up the path behind Jet's house.

Want to come see it?

- Yeah, you're absolutely invited to visit the treehouse.

It's quite impressive.

I'll check in with you in a couple of minutes.

Enjoy.

- Great.

- Goodie!

Come on, Ellen.

- I'll run your Earthie lemonade stand for now, kids.

- [Floyd chittering] - Have fun, Ellen!

- See, the design still isn't quite right.

When I run it through the simulation, the rocket starts to vibrate when it reaches the upper atmosphere.

- Here, did you try this?

[frantic beeping] Ah, whoops, undo, undo.

[buzzer blares] Oh, uh, sorry.

- Okay, what we need is something to relieve the pressure that's making it vibrate.

- Right, but what?

Ellen will be here any minute, and I sure wish we had it figured out by then.

[tense music] [machine whirring] - Yeah, good.

- Is that--is that a robot?

- Yep, that's Sydney Two.

We built her ourselves.

- I helped.

- You built your own robot?

- Well, my mom helped, too.

A lot.

- Your mom must be pretty cool.

- She is, and I want to be just like her when I grow up.

- Yes, mother, good.

- Wait, is that a rocket chair?

I've always wanted to try one of those.

- Finally, someone who appreciates my work.

- Wow, she's really brave.

[dramatic music] - Here we go!

[grunts] Ah, oh well, we can try again later.

- Absolutely.

Never give up just because something doesn't work the first time.

Do you know how many times we had to try before we were able to put a rocket into space?

- 5,987,242?

- Maybe not quite that many.

But definitely a lot.

- Come on, Ellen.

We want to show you our treehouse.

[upbeat music] - Wow!

These are beautiful!

- This one is about the time we went to the ice moon, Enceladus.

- Whoa, cool!

- And this is the valentine I made for dear little frozen Pluto.

- Aww.

- And this is a drawing of the cucumber sandwich I ate last week.

I did not want to forget it.

- Huh, you know, when I was a kid, I used to play space travel, too.

- You were a kid?

- Yeah, believe it or not.

I used to pretend my backpack was a jetpack, and I'd use it to discover new planets.

- Kind of like Commander Cressida!

- Come on, Ellen, I want to show you our observation station This is where we look at the stars.

Sean lets us use his telescope.

This path goes right there.

- Perfect.

- Um, astronaut Ellen Ochoa, do you have any tips for an aspiring astronaut?

I want to lead the first mission to Mars, but I'm a little bit nervous I won't pass all the tests.

- I wouldn't worry about it, Sean.

You have to be a grownup first before you can take those tests.

- I do?

- You're still a kid.

So you have lots of time.

- Really?

Ah, what a relief.

So I don't have to keep training all the time?

- Nope.

- [exhales] - [whistle blows] - As a kid, it's important to just play and use your imagination.

You use your imaginations to travel the whole solar system.

So let's play!

- Okay, what should we play?

- How about International Space Station?

I want to be Mission Control Mindy again.

- Sounds like fun.

How do you play?

- Well, first we set up the mission control at the bottom of the treehouse.

- The Sean gets into a spacesuit and gets on board the rocket.

- Then we do a countdown, and launch him into space.

We tried tying it with a string.

And even tried gluing it.

- And then what happened?

- Nothing worked!

- Oh, yeah.

Sometimes that happens.

In fact, I'm going to the DSA to look at a similar design and engineering problem.

I might get some good ideas by helping you with your rocket chair.

- Okay, wow, we're having an engineering discussion with astronaut Ellen Ochoa.

Pinch me!

Ow, I didn't mean it literally.

- Hmm, it seems like you need something to let the pressure out.

- That's money.

That's how people pay for their lemonade.

- You've been keeping them in the cash box, right?

- Um, I've been giving them out as napkins.

But I'll start doing that.

Good idea.

- [groans] - So, what would let the pressure out and fix this rocket chair?

- I think a valve or a spigot might do that.

[laughs] - [nervous laugh] What fun.

So we're excited you're here, and ready to show you our design for the Orion rocket part.

As you can see, we're still working on the design.

- Right.

Here's our design in action.

[computer beeps] - You know what, the kids and I were just talking about this, and I think I have an idea.

You see, Jet showed me his very innovative rocket chair.

- Oh, yeah!

- When Jet tried to fly it too high, the chair also shook a lot.

The kids tried different things, and they got the idea to try a valve spigot thingy, as the kids called it, from their lemonade machine.

- And this spigot thingy helped stop the vibrating?

- It did.

I suggest we try it for your design here.

- Okay, but it could take a while to design it.

It would be good to see one.

One valve spigot thingy.
