In a major breakthrough in its space programme, India on Saturday, successfully conducted the first test of its indigenously developed cryogenic rocket engine at a facility at Mahindragiri in Tamil Nadu.
"We had a very successful first cryogenic stage test at Mahindragiri at 6:20 pm. It is a major milestone in the development of rocket systems in the country," Indian Space Research Organisation Chairman G Madhavan Nair said.
The test at ISRO's Liquid Propulsion Centre at Mahindragiri lasted for 50 seconds, he said.
"Only developed countries have this stage. We have also qualified now," Nair said.
"We will go for one more long duration test in the next three or four weeks which will make it ready for flight."
The cryogenic rocket engine that ISRO successfully tested on Saturday, was equivalent to the "Russian stage" supplied earlier, Nair said.
