The countdown began on Sunday for the launch of India’s GSLV-D5, powered by indigenous cryogenic upper stage engine, which is being tested again after twin disasters three years ago. A successful launch on Monday evening (4.50 pm) would represent a new era in India’s space programme as it will usher in the capability of putting heavy satellites in space,
The rocket is to carry the communication satellite GSAT-14 from the second launch pad at the Sriharikota spaceport on Monday. The country needs the cryogenic engine in GSLVs to harness the capacity to carry heavier payloads up to five tones as the capability of putting heavier satellites in space orbit is crucial for future telecommunication needs and space exploration. The current Isro workhorse PSLVs can carry payloads of up to 1.5 tonnes in geosynchronous transfer orbit.
Manned flights to space too would be dependent on the power to put heavier objects in space orbit although manned flights are not a priority at the moment in Isro. GSLV-D5 is the eighth flight of the Geosynchronous Satellite Launch Vehicle and the fourth development flight. The mission assumes significance as the indigenously developed cryogenic upper stage (CUS) will be flight tested for the second time by Isro. The GSLV is a three stage/engine rocket.
