Answer: (a)
Related Facts:
- On 25 November 2021; Indigenous space startup Skyroot Aerospace successfully test-fired India’s first privately built cryogenic rocket engine Dhawan-1.
- Dhawan-1 is fuelled liquid propellant LNG and LoX.
- This new engine will be fixed in the upper stage of the Vikram-2 rocket of Skyroot Aerospace
- Pawan Kumar Chandan and Naga Bharath Daka, who formarly worked in ISRO, are the co-founder Skyroot Aerospace.
- They founded their company in 2018, which has been developing a series of three Vikram rockets, named after ISRO founder Vikram Sarabhai.
- Vikram rockets are designed especially for launching small satellites.
- Dhawan-1the made-in-India cryogenic engine has been developed using 3D printing with a superalloy, thus reducing manufacturing time by more than 95%.
- These are rocket propellants of the future, and with this test Skyroot Aerospace become one of the very few companies in the world to have successfully demonstrated this technology.
- Cryogenic engines are highly efficient rocket propulsion systems that use propellants at cryogenic temperatures (less than minus 150 deg C) and are highly suitable for upper stages of a rocket.
- At present only six countries, including the US, China, Russia, France, Japan and India, possess Cryogenic engine technology
- Isro has been using this technology to fire its GSLV rockets.
