Aer(
)sculptures
 A year after his first exposure of aer( )sculptures at solgel.com, Dr Michalou(di)s a visual Artist of MIT Center for Advanced Visual Studies, present the second series of aerogel sculptures. Among others enjoy the beauty of a "light" version of Aphrodite of Milos, the object of ecstatic wonder to millions of people. The 2003 aer( )sculptures will be exhibited in a special event at the 7 International Symposium of Aerogels, November 2-5 , Alexandria, Virginia (USA) April-August 2003

But even though star dust is the clay from which all things are formed, actually going into space to capture a pure sample is not an easy task. Yet NASA plans to do just that, using a lightweight insulating material called aerogel. Read the full story MacChesney from Bell Labs

Read the full story April 1998 Homesteading the Planets with Local MaterialsBy Simon Mansfield Source: SpaceDaily Building lunar and Martian bases from local on-site materials is a concept almost as old as space exploration. An attractive material for construction on the Moon is aerogel, an exceptional insulator of heat and sound. Aerogel has been described as frozen smoke since it weighs only slightly more than air. It's like foam rubber, only the cells are incredibly tiny, and their walls are equally thin. Sodium silicate (NaSiO2), a common mineral on both the Moon and Mars, could be used to produce high-density xerogels, or low-density aerogels.

Bakul Dave presented recent progress in the field at the
XI Int. Workshop on Glasses, Ceramics, Hybrids and Nanocomposites from Gels

The ability to sense and respond to
environment is a basic requirement of intelligence, and these materials constitute a novel
class of "smart" glasses.
