Rensselaer Researchers Use T-Rays to Uncover Defects in Space Shuttle Foam Sample
Troy, N.Y. - Using a technique pioneered by researchers at Rensselaer Polytechnic Institute, terahertz (THz) radiation has been used to uncover small defects in a sample of space shuttle foam. This nondestructive method could help National Aeronautical and Space Administration (NASA) officials examine the insulating foam that is applied to each shuttle's fuel tank prior to launch.
