Popularizing science

India was denied cryogenic (rocket fuel, a compound made up of air extracted on board from atmosphere and solid on-board fuel) technology. India developed this technology on its own and used this fuel in this rocket, called GSLV – Geo-synchronous Satelite Launch Vehicle, to put a heavy (weighing more than 2000 kilo) communication satellite in Earth orbit on December 19, 2018. Let us all study and understand how rockets work, what is an orbit and what is beyond Earth ! Enjoy Astrophysics !!
