Ever since the first astronaut went
to space almost 60 years ago,

over 500 people have blasted
out of Earth's atmosphere.

They lived and worked in
space at different times.

What if you were the first space baby
to be carried aboard a space station?

So, what's so different about
being born in space anyway?

Well, in fact, gravity on the
International Space Station

is about 90% as strong as it is
on the surface of the Earth.

So why do we see astronauts
floating around inside it?

at the same speed that the Earth's
surface is turning underneath it.

The space station is constantly
falling to Earth but it will never hit it.

The free fall is what causes microgravity,
making the astronauts float around.

So what would it be like
to be born weightless?

Before we get to the
birth part, let us just say

nobody's ever had sexual
intercourse on a space station,

It wouldn't be any kind of
out-of-this-world experience.

You may not have the blood flow
to get you or your partner aroused.

Sweat would build up around your
body making it wet and sticky all over.

how not to push your
partner away upon contact.

Conceiving a child would
be a whole other problem.

In addition to a low-gravity environment,
there's also so much radiation in space,

what kind of changes space conditions
would cause to a human embryo.

But let's imagine your pregnant mother
arrived on a space station to give birth to you.

The trip to space alone would
be hard enough on your mother.

Pushing you out of her body
without the help of gravity

If you made it out of the womb,
a low-gravity environment

would affect your body
systems as you grew up,

including your muscular
development and eyesight.

When grown-up astronauts
work aboard the space station,

their bone density depletes at
a rate of about 1% per month.

Because it takes no effort to float in space,

Now, since there's no way to
force a baby run on a treadmill

as you grew on the space station,
your skeleton might become deformed.

Your heart would be weak as it's never
had to work against Earth's gravity.

It would increase the probability of cancer,

dysfunction of the heart
and central nervous system,

If, after surviving all that,
you made the trip to Earth,

you wouldn't be able to
walk or balance properly.

You might also struggle with
interacting with people on Earth

since you grew up crammed into
a very small space your whole life.

Until someone invents a gravity polarizer

to generate artificial gravity
fields on a space station,

we probably shouldn't think
about having babies in space.

But once they do, how long
do you think it would it take

for us to become a galactic civilization?
