I'm Don Pettit. I'm a NASA astronaut
and I'm on the International Space Station
We're currently
about 240 nautical miles above the surface of Earth.
[...theme music starts...]
(242.5 nautical miles, NM) (almost 450 kilometers, KM)

[...music intensifies...]
[...music fades out...]
Space Station is a serious place.
We're doing serious researches,
scientific research and engineering research.
We have a Regenerative Life Support system,
which is a fancy way of saying
that we've got a toilet that you use,
and then a machine that goes,
"Chugga chugga chugga chugga.. chug,"
and then you go to the galley
and you make yourself a cup of coffee.
And that's exactly... what you are thinking it is.
(in-n-out by recycle)
And this is the kind of engineering research
that we're doing on Space Station.
It's needed so that
when we go to Mars, we won't run out of water.
And of course...
not only would you have angry birds
if you ran out of water,
you'd have "Angry Human Beings", too.
I want... to do some physics demonstrations
that involve some of the things
that you might see in the Angry Birds Game.
And, of course, I've got my Angry Bird here,
but we need a pig.
[...blowing sound...]
[...game melody starts...]
Well, I'm not very good at art.
It's a good thing I decided to be a scientist and an engineer
instead of an artist 'cause
I'd... I'd probably be starving by now.
Ok, Here... here is Pig.
And, of course, Pig is the archenemy of Angry Bird.
And Angry Bird, had...
some eggs!
[...piggies oink...] .
And Pig...
stole the eggs.
And don't ask me
how... I got the eggs on Sapce Station!
[...game melody goes...] .
I've got a bungee
spread across the hatchway...
And this bungee... is kind of like a slingshot.
And I'm gonna show...
the trajectory... that Red Bird is gonna have when I fire him with this orbital slingshot.
[...whistling melody...] .
Launching... Red Bird
into the space...
Well.. hey! we're already in the space!
[...gear tightening...]
(springs+Bird screams) Wohoo!
Look at that!
[bang!] Whoa, all..the way down!
[...whistling melody...] .
That's an example of a trajectory.
It's straight line... from our perspective here.
Gravity... will attract an object if it's moving in a straight line,
and it will no longer move in a straight line.
It gets bent... and goes in a curved trajectory.
And... guess what?
Astronauts have to worry about these things
because if you're in a rocket, and say...
you're trying to get... from one orbit
and rendez-vous a space station,
you end up going in curved trajectories,
and you need to know
how to fire your rocket engines
so that you can go from where you are
to where you want to be.
[...game melody goes...] .
And if you understand the math,
if you understand the physics,
it will allow you to go out...
and get... a neat job.
A job sort of like mine
where you're an astronaut
and you can fly in space.
(So) Learn about these subjects in school.
You can also learn about these subjects while you're playing games.
(And...) What happens...
when... something like an Angry Bird
gets their eggs
[bang!] gets their eggs
stolen by pig?
This is all that's left of Pig after Pig got exploded.
And we got to see all of this in a weightless environment,
which is what the Angry Birds Space game is going to be like
with gravity fields from planetary bodies.
