Sriharikota, Apr 15: The Indian Space Research Organisation (ISRO) launched the landmark geo-synchronous satellite (GSLV-D3) on Thursday, Apr 15 at 4: 27 pm here.
The satellite lifted off with a geo-stationary satellite (GSAT-4) as its main payload.
This is the first time India has fired its own cryogenic rocket engine to launch an advanced communication satellite.
If this is successful, India will enter the elite space club alongside the five countries, which have the cryogenic engine upper stage technology to launch heavier satellites in geostationary orbit.
The five countries are United States, Russia, France, Japan and China.
India will then become the sixth country in the world to have earned the credit of designing and developing the cryogenic technology.
