First Space-Produced Aerogel Made on Space Sciences Laboratory Rocket Flight

October 8, 1996: Results are now beginning to become available from the April 3, 1996 rocket flight to produce the first space-made Aerogel. As described in the June 19, 1996 Aerogel Headline , Aerogel is the lightest solid known to mankind, with only three times the density of air. Aerogel, because of its appearence is sometimes referred to as "frozen smoke". Aerogel produced on the ground typically displays a blue haze or has a slight cloudiness to its appearence. This feature is believed to be caused by impurities and variations in the size of small pores in the Aerogel material. Scientists are trying to eliminate this haze so that the insulator might be used in window panes and other applications where transparency is important.
