ISRO successfully test launches scramjet engine from Sriharikota
The Indian Space Research Organisation on Sunday successfully test-fired its Scramjet Rocket Engine, which will use oxygen from the atmosphere thereby reducing launch cost, from the spaceport of Sriharikota.
“The test fire took place around 6 AM from the Satish Dhawan Space Centre in Sriharikota, it was successful” an official of the city-headquartered space agency told PTI.
Usually rocket engines carry both fuel and oxidiser on board for combustion, but these newly developed engines will use oxygen from the atmosphere and thereby reducing the cost.
It also reduces the weight of the vehicle during lift-off, ISRO said.
President Pranb Mukherjee congratulated ISRO for the successful test.
“Hearty congratulations ISRO on successful test of futuristic scramjet rocket engine, India is proud of you,” he said in a tweet.
Meanwhile, the launch of the Indian weather satellite, INSAT-3DR, which was slated for August 28 has now been postponed to September 8.
Queried about the change in launch plan Krishnan said: “While carrying out the tests there was a technical issue found with a satellite component. It has been sorted out now and hence the delay.”
He said the GSLV rocket that would carry the weather satellite INSAT-3DR is fully assembled.
The weather satellite will be mounted on to the rocket in three to four days.
According to officials, the ISRO will launch ScatSat — a weather monitoring and forecasting satellite — with polar satellite launch vehicle end of next month.
The Indian satellite will be a co-passenger to an Algerian satellite.
Both the satellites will be put into different orbits. So the fourth engine of the rocket will be switched off after ejecting ScatSat first. Then after a gap of around 30 minutes, the engine will be switched on and put the Algerian satellite into its intended orbit.
