What are Aerogels? Aerogels were first created by Samuel Stephens Kistler in 1951. Strengths Aerogels are solid, but can be less dense then air. Despite their sparse molecular structure aerogels are strong. Aerogels are excellent insulators. Weaknesses Aerogels are traditionally expensive and difficult to manufacture, and they are difficult to handle.

Practical Applications Aerogels have numerous applications. NASA used an aerogel to capture space dust, with the Stardust spacecraft. NASA also used an aerogel to insulate the Mars Rover. The US Navy is investigating the use of aerogels to provide more insulation for divers. And aerogels are also being used in detectors for
