Skyroot Tests India’s First Privately Developed Cryogenic Rocket
The engine uses liquid natural gas (LNG) and liquid oxygen (LoX) at cryogenic temperatures as propellants, making it suitable for upper stage propulsion like ISRO’s CE-7.5 and CE-20Source: SkyrootHyderabad-based spacetech startup Skyroot Aerospace has tested India’s first privately developed cryogenic rocket—Dhawan 1. Cryogenic engines are rocket propulsion systems that use propellants stored at cryogenic temperatures (less than -150°C). Founded in 2018 by Pawan Kumar Chandana and Naga Bharat Daka, Skyroot Aerospace is developing some of India’s first privately built space launch vehicles. “The engine uses liquid natural gas (LNG) and liquid oxygen (LoX) at cryogenic temperatures as propellants, which are high performance, low-cost, and green. ISRO currently uses its CE-7.5 and CE-20 cryogenic rocket engines, both of which are powered by a mixture of LoX and liquid hydrogen (LH₂).
