Skyroot Aerospace

Skyroot Aerospace Private Limited is an Indian private aerospace manufacturer and commercial launch service provider located in Hyderabad, Telangana. The company was founded by former engineers and scientists from ISRO, DRDO, and various aerospace companies and it aims to develop and launch its own series of small lift launch vehicles. 
History.
Skyroot Aerospace was formed in January 2017 by former Indian Space Research Organisation scientists Pawan Kumar Chandana, Naga Bharath Daka and Vasudevan Gnanagandhi as well as a small group of entrepreneurs including CureFit founders Mukesh Bansal and Ankit Nagor. Skyroot has raised $4.3 million, including from space and defence contractor Solar Industries, and is aiming to secure another $15 million in funding by 2021.
The company has been developing its first launch vehicle, the “Vikram-I,” which is on track for its initial launch around December 2021. In August 2020, Skyroot first came into the limelight when it test-fired the "Raman-I" solid-fuel upper stage (named after C. V. Raman). This solid-fuel upper stage is a component of "Vikram-I" and Skyroot was the first Indian private entity to test such a stage.
On 25 September 2020, Skyroot Aerospace unveiled the "Dhawan-1" upper stage cryogenic engine that will power heavier-lift systems such as "Vikram-II." This is the first cryogenic engine in India that will use liquefied natural gas (LNG) as fuel; this fuel has the advantages of being clean, re-usable and suited for long duration space missions. "Dhawan-1" is 3D printed and designed with a regenerative cooling configuration.
On 20 November 2020, Skyroot Aerospace entered into a memorandum of understanding with Dhruva Space, an Indian private satellite manufacturer. On 22 December 2020, Skyroot tested the solid-fuel rocket engine Kalam-5, the first of five planned carbon-composite "Kalam" rocket motors which are expected to power its launch vehicles. The test happened in Nagpur at a private test facility owned by Solar Industries, which is also an investor in Skyroot. In the name "Kalam-5""", the 5 refers to the peak sea level thrust of 5.3kN. The final engine in the series will be four times the size of "Kalam-5".
On 2 February 2021, ISRO and Skyroot Aerospace signed a NDA. The NDA will allow Skroot Aerospace to access the facilities and technical expertise in ISRO centers to develop their launch vehicles. On 8 February 2021, Skyroot Aerospace Announced that they partnered with Bellatrix Aerospace to use the Orbital Transfer Vehicle of Bellatrix Aerospace with their Vikram series of Launch Vehicles. 
Launch vehicles.
The firm has been working on its "Vikram" series of expendable small lift launchers. Rockets are designed for very quick assemblies, as fast as 24 to 72 hours. They have plans to develop a fully reusable vehicle.
