The rise of casualties on Siachen- the world’s highest battlefield – has led the Indian Space Research Organisation to develop and manufacture the world’s lightest material called silica aerogel or ‘blue air’ to keep soldiers warm.
The material that is useful in outer space and on Earth has extraordinary thermal resistance and can be used in uniforms to keep soldiers warm in freezing temperatures. The material also known as ‘frozen smoke’ is manufactured by ISRO’s research center. It is said to be so light that it can be placed on a flower head.
It is hoped that this indigenous creation of India will be used in rocket engines for insulation, and for soldiers it can be used in their insoles, thermal jackets, and even for window glazing.
