Diamond Barrier Plus™ technology was developed by NASA over 40 years ago to protect astronauts in the Apollo program from temperatures that ranged from 250 degrees above zero to 460 degrees below zero Fahrenheit.

This reflective insulation has been applied to every spacecraft since then, including unmanned spacecraft with delicate instruments that need protection from temperature extremes. The same technology is also applied to astronaut's space suits, protecting them during space walks.
