WEBVTT - How do space suits work?

0:00:00.520 --> 0:00:03.600
<v Speaker 1>Welcome to brain Stuff from house stuff works dot com

0:00:03.600 --> 0:00:16.400
<v Speaker 1>where smart happens Hi Marshall Brain Between the Space Shuttle

0:00:16.440 --> 0:00:19.040
<v Speaker 1>and the Space station, it seems like someone is out

0:00:19.160 --> 0:00:22.880
<v Speaker 1>spacewalking just about every week now. The space suits that

0:00:22.920 --> 0:00:26.080
<v Speaker 1>the astronauts where are one of the most interesting parts

0:00:26.079 --> 0:00:29.280
<v Speaker 1>of space walking. A space suit has to do at

0:00:29.360 --> 0:00:34.479
<v Speaker 1>least three things to protect the astronaut. First, it provides oxygen. Second,

0:00:34.560 --> 0:00:38.200
<v Speaker 1>it has to keep pressurized air all around the astronaut's body.

0:00:38.680 --> 0:00:41.240
<v Speaker 1>One of the problems that the pressure created in early

0:00:41.320 --> 0:00:45.320
<v Speaker 1>space suits is a balloon effect. Modern suits control the

0:00:45.320 --> 0:00:48.600
<v Speaker 1>balloon effect by using low pressure inside the suit and

0:00:48.640 --> 0:00:52.280
<v Speaker 1>a hard fiberglass torso section. The third thing that the

0:00:52.320 --> 0:00:56.120
<v Speaker 1>suit has to do is control the astronauts temperature in space.

0:00:56.280 --> 0:00:59.040
<v Speaker 1>It's two d and fifty degrees in the sun and

0:00:59.200 --> 0:01:02.520
<v Speaker 1>minus a hundred and fifty degrees in the shade. Long

0:01:02.640 --> 0:01:08.880
<v Speaker 1>underwear laced with water filled tubes, even things out for

0:01:08.959 --> 0:01:11.360
<v Speaker 1>more illness and thousands of other topics. Does that how
