US scientists have developed a ceramic airgel that is extremely light, durable and heat resistant. It could be used, for example, for the insulating tiles of spacecraft.
99% of the ceramic airgel consists of air. It is very flexible and heat resistant.

When a Space Shuttle enters the Earth’s atmosphere from a space flight, extreme heat develops on the outer shell. Super insulators serve as a barrier in such situations to protect (more…)
