How Do Space Suits Work?

[MUSIC PLAYING] 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.
