It’s great to see so many of you interested in this series on survival in outer space. Tonight I’m going to talk about the most basic aspect of survival—the space suit. When most of you imagine an astronaut, that’s probably the first thing that comes to mind, right? Well, without space suit, it would not be possible for us to survive in space. For example, outer space is a vacuum. There’s not gravity or air pressure. Without protection, a body would explode. What’s more, we’d cook in the sun or freeze in the shade with temperature’s ranging from a toasty 300 degrees above to a cool 300 degrees below zero Fahrenheit. The space suit that NASA has developed is truly a marvel. This photo enlargement here is a left side’s image of an actual space suit worn by astronauts on the last space shuttle mission. This part is the torso. It’s made of seven extremely durable layers. This thick insulation protects against temperature extremes and radiation. Next is what they call a bladder of oxygen. That’s an inflatable sack filled with oxygen to simulate atmospheric pressure. This bladder presses against the body with the same force as the earth atmospheric sea level. The innermost layers provide liquid cooling and ventilation. Despite all the layers, the suit is flexible allowing free movement, so we can walk. Another really sophisticated part of the space suit is the helmet. I brought one along to show you. Can I have a volunteer come and demonstrate?
15. What will cause an unprotected human body to explode in outer space?
16. Where is the bladder of oxygen located?
17. What does the speaker show the audience as he describes the main part of the space suit?
18. What will probably happen next?
