Scientists at Marshall Space Flight Center (MSFC) have been studying the properties of Aerogel for several years. Aerogel, the lightest solid known to man, has displayed a high quality for insulation. Because of its smoky countenance, it has yet to be used as an insulation on windows, but has been used in the space program on the rover Sojourner, and has been used as insulation in the walls of houses and in automobile engine compartments. As heat is applied to Aerogel, scientist Dr. David Noever of Space Sciences Laboratory, Principal Investigator of Aerogel, studies for its properties trying to uncover the secret to making Aerogel a clear substance. Once found, Aerogel will be a major component in the future of glass insulation.
