I wrote those words when I was 12 years old.

Mars is a planet ready for life.

In 20 hours, 6 astronauts will travel to Mars not to visit, but to live there.

Zero gravity, it's uncharted territory!

Sir.

We lost her.

His heart will simply not have the strength in the Earth gravity...

bones will be brittle.

He wouldn't even survive the trip back to Earth!

So the child remains classified?

On Mars?

Yes.

Gardner is a sixteen-year-old boy.

He's met less than 15 people in his life.

What if no one knows I exist?

I'm raised by scientists.

He knows about Earth.

Hey Tulsa!

I'm outta here the second I turn 18.

I just wish I could go with you!

And he knows it's all happening without him.

Bring him home!

How am I supposed to act with the people?

Docking in T-minus one minute.

I've got so many questions about Mars!

Not as many as I have about Earth!

They're so many colors.

Can I stay?

I need you to do more tests.

Nothing has changed.

I want to get out there!

There's been a breach!

We need teams in the airport ... Amtrak station ...

He can't survive.

How do we know he is going to see her?

'Cause she is the only person he knows on Earth.

And he's a romantic.

Hey Tulsa.

Tell me where you're really from.

Mars!

Just because something sounds crazy doesn't mean it's not true!

Wow! What is it?

It's just a horse.

Where are we going?

You wanted to see the world!

What's your favorite thing about Earth?

Rain!

Gardner come with me now!

No!

This is my life!

Get in! We're taking off!

You're the most beautiful girl I've ever seen!

You don't just blurt that out just like that.

Why wouldn't I?

His heart can't handle our gravity!

He wasn't lying.

He's running out of time.

I was scared I wouldn't know how to be human.

You made me human.

Tulsa, what's your favorite thing about Earth?

You are, Gardner.
