Indian space research organization launches today launches GSLV D6.
With its five development flights, this is the third time indigenously developed cryogenic engine is carried onboard during GSLV flights. GSAT-6 satellite is launched in this flight from Satish dawan space center. This is the second consecutive flight of indigenously engine with the capability of launching with the weight of 2.5 tonne.
ISRO scientist spent nearly around two decades to master this technology and 400 crore was spent to conquer this type of technology. This cryogenic engine is more efficient by providing higher thrust per propellant burnt. This is tremendous hard work of the scientist to developement of the cryogenic engine and result is clearly demonstrated with all the system working normally.
In 2014 GSLV first successfully launched and now time came when ISRO had set a target to launch at two satellite from GSLV every year. And next launch will be on June and July next year. Before developing own engine, Indian heavy satellites are launched by European satellite agencies Ariane, and this help India to save large amount of foreign exchange.
GSLV D6 was launch from second launchpad of Satish dawan space center. Weighing around 2117 kg GSAT 6 was launched successfully and will S-Band communication service to the country. After reaching geosynchronous transfer orbit then it will use its own propulsive system to geostationary orbital.
The cryogenic stage is technically a very complex system compared to solid or earth-storable liquid propellant stages due to its use of propellants at extremely low temperatures and the associated thermal and structural challenges. The main engine and two smaller steering engines of CUS together.
