On June 5, 2017 the first developmental flight (GSLV MkIII-D1) of India's heavy lift launch vehicle GSLV Mk-III was successfully conducted from Satish Dhawan Space Centre SHAR, Sriharikota with the launch of GSAT-19 satellite.
Weighing 3136 kg at lift-off, GSAT-19 is the heaviest satellite launched from the Indian soil.
After a twenty five and a half hour smooth countdown, the mission began with the launch of the 640 ton GSLV Mk-III at 5:28 pm IST from the Second Launch Pad as scheduled with the ignition of its two S200 solid strap-on boosters.
The upper stage of GSLV MkIII vehicle is a new cryogenic stage (C25) indigenously configured, designed and realised by ISRO.
The cryogenic stage used liquid Hydrogen and liquid Oxygen as propellants with a total loading of 28 tons.
The stage is powered by a 20 ton thrust cryogenic engine (CE20) operating on ‘gas generator cycle’.
The performance of the engine and stage during the mission was as predicted. About sixteen minutes after lift-off, GSAT-19 satellite was successfully placed in orbit.
Soon after its separation from GSLV, the Master Control Facility (MCF) at Hassan in Karnataka assumed control of the satellite.
GSAT-19 is a high throughput communication satellite.
