ISRO to use indigenous Cryogenic upper stage in GSLV

Bangalore, Aug 19 (UNI) The indigenous upper stage of Cryogenic engine, successfully tested at Mahendragiri facility of Indian Space Research Organisation (ISRO) last week, will be used in the GSLV to be launched next year.

Talking to newspersons on the sidelines of a book release function here last night, ISRO Chairman N Madhavan Nair said he was completely satisfied with the successful eight minute test of the upper stage of Cryogenic engine and added there was no need for further tests. It would be fitted on the 160 foot GSLV which would be launched early next year.

The ISRO's attempts to launch GSLV that could carry four tonnes of payload, had been hampered due to sanctions imposed on the transfer of technology of the Cryogenic engine by the US, after its second nuclear test. However, ISRO had worked steadfastly since then to achieve self sufficiency in this field, he said.

The engine had run for 6,000 seconds against the required 720 seconds in the flight. However, there was no need to go for another test as all the parameters achieved so far had been satisfactory and the results were pleasing, he said.
