Speaker 1: where smart happens Hi Marshall Brain Between the Space Shuttle
Speaker 1: and the Space station, it seems like someone is out
Speaker 1: spacewalking just about every week now. The space suits that
Speaker 1: the astronauts where are one of the most interesting parts
Speaker 1: of space walking. A space suit has to do at
Speaker 1: least three things to protect the astronaut. First, it provides oxygen. Second,
Speaker 1: it has to keep pressurized air all around the astronaut's body.
Speaker 1: One of the problems that the pressure created in early
Speaker 1: space suits is a balloon effect. Modern suits control the
Speaker 1: balloon effect by using low pressure inside the suit and
Speaker 1: a hard fiberglass torso section. The third thing that the
Speaker 1: suit has to do is control the astronauts temperature in space.
Speaker 1: It's two d and fifty degrees in the sun and
Speaker 1: minus a hundred and fifty degrees in the shade. Long
Speaker 1: underwear laced with water filled tubes, even things out for
Speaker 1: more illness and thousands of other topics. Does that how
