I know there was a shuttle mission in 1998 called STS-95 where an experiment was conducted by John Glenn, but I can't find anywhere that has the results.

If you don't know the answer, but could point me in the right direction it would be greatly appreciated. Thank you all

Okay, so the info that the guys provided - I already read, but still no answer about CLEAR aerogels. Please don't copy and paste from a source and not cite it. Thanks again!

Start with the site below. Contact NASA directly for information about any published results to experiments.

Some information is not available to the public, especially if it has military applications.

Scientific American described the future of the computing industry as perhaps relying on new chip material choices, such as aerogel (a sample is pictured at left), for maintaining the progress of a remarkable story in industrial growth - the growth of computing speed, sometimes called Moore's law, depends on radical choices in next stage manufacturing. Moore's law, named after the former CEO of Intel, states that the computing power of chip manufacturing doubles every 18 months. Since its formulation in the 1960's, 30 years of experience in the silicon wafer industry has relentlessly borne out this geometric doubling. No other industry in history has ever come close to matching that scale of progression. Over the next decade, this would translate the current state of the art (300 MHz) desktop PC into a whopping 24 GHz machine!
