Hey.
This is Robert Lamb from
Stuff to Blow Your Mind,
and I'm here to talk to
you about spacesuits.
Now everybody wants
to go on a space walk,
but you cannot do it naked.
I can't stress that enough.
You're going to need to
invest in a good spacesuit,
and you're going to
want that spacesuit
to do three things for you.
First, the suit has
to provide oxygen.
You're going to have to be
able to breathe in that thing.
All right?
And then it's going
to have to provide
pressurized air all
around your body.
The problem in some
of the earlier suits
is it created something
called the balloon effect.
Modern suits control
the balloon effect
by using a low pressure inside
the suit and a hard fiberglass
torso section.
The third thing that
the suit has to do
is control the
astronaut's temperature.
Now out in space, it is a
balmy 250 degrees in the sun
and a chilly minus 150
degrees in the shade.
So you're going to wear
long underwear laced
with tubing that's
filled with cool water
to keep everything chill.
So there you go.
Spacesuits in a nutshell.
