ISRO successfully launched India’s heaviest rocket, Geosynchronous Satellite Launch Vehicle MK III on June 5, 2017. GSLV is nicknamed ‘Fatboy’. It weighs 640 tonnes and carried 3,136 kg communication satellite GSAT-19. The rocket is as heavy as 200 adult elephants. The rocket was launched using cryogenic engine technology. Scientists have been working on this mission for the last 15 years. Till now, ISRO had to rely on foreign launchers for satellites weighing more than 2300 kg.
The whole country should be proud of it. We can even hope that ISRO will send astronauts to space in the near future.
