Modern Marvels: It Came From Outer Space
Discover how essential space travel technologies have journeyed back to Earth with surprising and indispensable commercial applications. For example, paint that can withstand the heat of reentry now protects our steel-framed high-rises from collapsing in a fire. Batteries that can take a sports car from zero to 60 in four seconds also keep our satellites in orbit. The oxygen tank used by firefighters to save countless lives is just like the one used by our astronauts during the Apollo missions. These and many ordinary objects are traced back to their NASA roots, where they originally had the right stuff.
