Reusable Scramjet Engine Tested Successfully
ISRO has successfully tested its Supersonic Combustion Ramjet (Scramjet), which is meant to power future reusable launch vehicles that will spend much of their time accelerating through the atmosphere to reach orbital velocity. A scramjet is distinct from a rocket, in that it burns fuel by using air from the atmosphere rather than onboard liquid oxygen. The advantage of this is in not having to carry the weight of that onboard oxygen, which normally makes up most of the starting launch mass of any rocket - and thus the vehicle can be far lighter.
