India's geosynchronous satellite launch vehicle fails

April 15

Indian Space Research Organization (ISRO) Thursday suffered a setback when the Geosynchronous Satellite Launch Vehicle (GSLV-D3), which was launched using an Indian-designed and built cryogenic engine for the first time, deviated from its path and thus failed.

"The control was lost as two small cryo engines did not ignite, " ISRO Chairman K. Radhakrishnan said here. "We will put all efforts to ensure that the next flight with the indigenous cryogenic engine takes place within a year."

The rocket deviated from its path and the scientists monitoring the launch said that they did not receive any speed and altitude data from the vehicle.

The rocket had lifted from the ISRO Satish Dhawan Space Center (SDSC) launch pad at Sriharikota island, off the coast of the southeastern state of Andhra Pradesh at 16:27 p.m. local time.

However, the launch was not perfect with the GSLV-D3 failing to send any data after 500 seconds of taking off.

The GSLV-D3 was to put the 2.2-ton communication satellite GSAT- 4 into the geo-transfer orbit (GTO) on Thursday evening.

Till now, ISRO had been using Russian cryogenic engines in its GSLV missions as the United States had forced Moscow not to sell the cryogenic technology to India in 1992 and it took India more than 18 years to develop this cryogenic engine as technology.
