CHENNAI: The Indian Space Research Organisation (ISRO) is gearing up to test its scramjet engine on Sunday while the launch of weather satellite INSAT-3DR with the geosynchronous satellite launch vehicle (GSLV-MkII) has been postponed to September, a senior official said on Saturday.

India's rocket port is located at Satish Dhawan Space Centre (SDSC) in Sriharikota in Andhra Pradesh around 80km from here.

"The launch of RH-560 sounding rocket to test the scramjet (air breathing) engine is slated for 6 a.m. on Sunday," P. Kunhi Krishnan, director of SDSC told IANS.

The rocket will take off at 6 a.m. if the wind speed is conducive for the launch or it may be launched bit later.

The scramjet engine, used only during the atmospheric phase of the rocket's flight, will help in bringing down the launch cost by reducing the amount of oxidiser to be carried along with the fuel.

Earlier Krishnan had said the Indian weather satellite will be launched on August 28 which 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 (PSLV) 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.
