Andy the astronaut - lunar space suit #nasa

To better understand the purpose of a lunar space suit, let's let our friend Andy astronaut demonstrate the hazards lunar explorers will encounter. If Andy were to step out on the surface of the moon without a space suit, this is what would happen. In the near vacuum of space, the gases within his body would immediately expand. His blood would appear to boil from the rapid expansion of gases coming out of solution in his bloodstream. Andy would soon feel the effects of another condition of space, lack of oxygen. After 20 seconds in a vacuum and without oxygen, Andy would be trading in his astronaut wings for a more permanent variety. [Music]
