Scientists in Vikram Sarabhai Space Centre lab recently manufactured the world’s lightest material called silica aerogel or blue air.

  • The Space Centre told that it is the world’s lightest synthetic material made by man. It is a highly guarded technology. ISRO have indigenously made it in India.

Properties of Silica Aerogel:

  • The blue air has excellent thermal resistance.
  • It is so light weight that it can be delicately placed on a flower head.
  • Aerogel is also called Frozen smoke, the matrix of aerogel is made up of 99 per cent air
  • The material is very fragile and brittle and scientists are still finding ways to make it tough and resilient.


  • The aerogel can used as filler in soldiers’ uniforms to save lives of soldiers at the Siachen glacier.
  • It can be handy in insulating rocket engines as it can be used both in space and on Earth.
  • It can be also used to make light weight clothing. It can be also painted on windows in to keep buildings cool or warm.
  • ISRO is planning to use this material on moon rover in Chandryaan-2 mission of India.
