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)
-
I S S

[...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.
