ISRO Successfully Tests Semi-Cryogenic Engine for Future Heavy-Lift Missions BVC The Indian Space Research Organisation (ISRO) has achieved another significant milestone in its pursuit of advanced space propulsion technology. On [date], ISRO successfully conducted a crucial test of its semi-cryogenic engine, a key component required for future heavy-lift space missions. This breakthrough is expected to enhance India's space capabilities, paving the way for ambitious interplanetary missions and high-payload satellite launches. Image What is a Semi-Cryogenic Engine? A semi-cryogenic engine is a type of rocket propulsion system that uses a combination of liquid oxygen (LOX) as an oxidizer and kerosene-based fuel. Unlike fully cryogenic engines that use both LOX and liquid hydrogen (LH2), semi-cryogenic engines are more cost-effective and offer higher thrust, making them ideal for heavy-lift launch vehicles. Key Advantages of Semi-Cryogenic Engines Higher Thrust: Provides greater l...
