Bringing Space Technology to Earth(생략)
What do you feel when you see a smoke detector? Do you ever feel like an astronaut? No? Well, the next time you see one, try imagining that it's part of your spacecraft's caution and warning system. It might sound surprising, but smoke detectors were originally found on spacecraft before they were used to save lives on earth.
In fact, much of the technology developed by NASA and other space agencies has eventually been adapted for use in our everyday lives. These adapted space technologies are known as "space spin-offs," and they have been enhancing our lives on earth since the beginning of space exploration.
Currently, there are more than 30,000 space spin-offs that can be found in hospitals, stores, offices, and homes. In the early years of space travel, these psin-offs generally occurred by chance, when a practical use of a new technology was accidentally discovered. These days, however, space researchers work together with industrial scientists to find ways to make space spin-offs useful here on earth.

Fabrics(생략)
Fabrics designed for space travel have proven to have many practical uses. In space, aluminized fabric is used to protect spacecraft from extreme temperatures. on earth, it has been used in a number of products, including survival blankets. Fire proof material use to make spacesuits has been adapted to make fireproof clothes for children and special suits for firefighters. Also, the "cool suits" worn by the astronauts -- made of a net-like fabric with water-filled tubes -- are now used by professional race car drivers and others who work in extremely hot places.
