ISRO successfully test launches Scramjet engine
The Indian Space Research Organisation (ISRO) successfully tested its Scramjet (Supersonic Combusting Ramjet) engine from the Satish Dhawan Space Centre in Sriharikota on Sunday. Known as the air-breathing engine, it would be used only during the atmospheric phase of the rocket's flight and will help bring down the launch cost by reducing the amount of oxidiser required​ along with fuel.
