ISRO's first indigenous cryogenic engine successfully launches GSLV-D5 rocket
Sunday, January 5, was a landmark day for Indian Space Research Organisation (ISRO) after having successfully launched GSLV-D5 rocket with an indigenous cryogenic engine. The rocket was launched at 4:18 pm from the Satish Dhawan Space Centre in Sriharikota, reported IRSO's website www.isro.org. Earlier out of seven launches, four had failed. This launch was after two successive failures.
The best thing is that this time the engine was fabricated in India
itself – a feather in its cap. Earlier, seven cryogenic engines were received from Russia. The indigenous cryogenic engine uses liquid hydrogen as fuel and liquid oxygen as oxidizer to propel the rocket. Cryogenics, the science of extremely low temperatures, had posed a great challenge to ISRO's scientists to develop the engine indigenously.
Besides, the successful launch, seventeen minutes after lift off, ISRO's team of space scientists injected GSAT-14 communication satellite into geosynchronous transfer orbit.
Lauding the precise launch, ISRO chairman K Radhakrishnan said, "This shows the maturity of the team. We dedicate the proud moment for the country." It is said that the launch was so precise that the satellite was put just 40 metres within the 179 km perigee and only 50km of the 36,000km apogee. With this feat, India has become the sixth nation in the world to develop its own cryogenic engine.
A cryogenic rocket engine uses a cryogenic fuel and oxidizer, meaning that the two gases, hydrogen and oxygen, are liquefied and stored at very low temperatures.
