Aerogel is not like conventional foams, but is a special porous material. This exotic substance has many unusual properties, such as low thermal conductivity, refractive index and sound speed - in addition to its exceptional ability to capture fast moving dust. Aerogel is made by high temperature and pressure-critical-point drying of a gel composed of colloidal silica structural units filled with solvents. Aerogel was prepared and flight qualified at the NASA's Jet Propulsion Laboratory (JPL). JPL also produced aerogel for the Mars Pathfinder and Stardust missions. This particular JPL-made silica aerogel approaches the density of air. It is strong and easily survives launch and space environments.

making the "dream"....

Dr. MICHALOU(di)S  with Dr. Steven Jones in Jet Propulsion Laboratory (NASA), in February 2005, when the artist started the research for the creation of the first aer()sculptures hover in the air. This dream was realised @ Museum of Cycladic Art, Athens-Greece, in October 2006, thanks to the extra light material silica aerogel and electromagnetic fields.
