Context: Skyroot Aerospace, a Hyderabad-based space technology startup, has successfully test-fired  tested Dhawan-1 last month. 

About Dhawan-1

• Dhawan-1 is India’s first privately developed, fully cryogenic rocket engine. 
• It runs on two high-performance rocket propellants — liquid natural gas (LNG) and liquid oxygen (LoX).
• The engine was developed using 3D printing with a superalloy.

Other projects by Skyroot

• Skyroot is working simultaneously on different stages of both solid propulsion and liquid propulsion engines.
• It is named after eminent scientists, like Kalam (Abdul Kalam) series for the former and Dhawan (Satish Dhawan).
• The launch vehicles are named after Vikram Sarabhai.

What is Vikram?

• Vikram is a series of launch vehicles to be launched by Skyroot space. These vehicles are specially crafted for the small satellite market. 
• Vikram-1:  It is based on a solid propulsion engine. After Skyroot successfully designed and developed the solid propulsion rocket engine, it became the first private firm in the country to do so.
• Vikram-2: This vehicle is using a cryogenic engine. It will be launched into orbit in the next 2 years.
