Indian Space Research Organisation (ISRO) have developed world’s lightest synthetic material named ‘silica aerogel’ or ‘blue air’. ISRO’s scientist from Thiruvananthapuram developed it. Silica Aerogel is the lightest artificial material which was never before made.

Properties of Silica Aerogel:

  • Light in weight
  • It can be carefully placed on a flower head.
  • Excellent thermal resistance.
  • Acts as a good insulator.
  • The surrounding substance of aerogel is made up of 99 % air.
  • At its present development, it is still breakable and very hard.

Uses or applications of Silica Aerogel:

  • It can be used both in space and on Earth, so used to protect rocket engines as.
  • Used as filler in soldiers’ uniforms to save lives of soldiers at the Siachen glacier.
  • It can be also used to develop light weight clothing.
  • It can be used as paint on windows to keep buildings cool or warm.
  • It will be used on moon rover in Chandryaan-2 by ISRO’s mission of India.

About ISRO:

  • ISRO stands for Indian Space Research Organization.
  • It is space agency of Indian Government and it’s headquarter is at Bangalore, India.
  • It was formed in 1969 with name Indian National Committee for Space Research (INCOSPAR).
  • First satellite named ‘Aryabhata’ was built by ISRO and launched by Soviet Union in 1975.
