Hyderabad-based Skyroot Aerospace has established India's capability for private orbital space launches, developing the nation's first privately-built rocket system designed to reach orbit. This milestone follows the successful sub-orbital flight of its Vikram-S demonstrator in November 2022, paving the way for the upcoming Vikram-1 orbital vehicle and positioning India as a key player in the global private space economy.

The journey commenced with the "Prarambh" mission, which saw the Vikram-S sub-orbital rocket launched on November 18, 2022, from the Satish Dhawan Space Centre (SDSC) in Sriharikota. This inaugural mission, carrying three payloads including one from Chennai-based SpaceKidz India, achieved a peak altitude of 89.5 kilometers. The flight successfully validated critical flight systems, including avionics, telemetry, guidance, and control for the Vikram series of launch vehicles. The mission marked the first time a privately developed Indian rocket successfully reached space.

Building on the Vikram-S success, Skyroot is preparing for the orbital launch of its Vikram-1 rocket. This larger, multi-stage launch vehicle is designed to carry payloads of up to 480 kg to low-Earth orbit. The Vikram-1 incorporates advanced technologies such as an all-carbon fiber structure, 3D-printed liquid propulsion engines, and a precise spin-stabilized upper stage for satellite injection. Its development targets the burgeoning small satellite market, offering dedicated and cost-effective launch services to commercial clients.

The emergence of Skyroot's orbital capabilities represents a significant advancement for India's space sector, historically dominated by the Indian Space Research Organisation (ISRO). This development aligns with the Indian government's "Atmanirbhar Bharat" (self-reliant India) initiative, fostering indigenous technological growth and reducing reliance on international launch providers for commercial small satellite launches. The company, founded by Pawan Kumar Chandana and Naga Bharath Daka, has received authorizations and support from the Indian National Space Promotion and Authorization Centre (IN-SPACe), the regulatory body tasked with promoting and overseeing private participation in space activities under the Department of Space.

Key technological innovations featured in Skyroot's rocket development include:

  • Kalam Series Engines: Utilizes 3D-printed engines, such as the Kalam-100 for the first stage of Vikram-1 and the 3D-printed liquid-fueled Kalam-5 engine for the upper stage, reducing manufacturing complexity and lead times.
  • All-Carbon Fibre Structure: Significantly reduces the vehicle's inert mass, enhancing payload capacity and overall efficiency.
  • Modular Design: Allows for rapid assembly and customized mission profiles, adapting to diverse customer requirements.
  • Sub-orbital to Orbital Progression: A methodical development strategy, proving technologies on the Vikram-S demonstrator before scaling to the orbital Vikram-1 vehicle.

With the Vikram-1's orbital debut anticipated in the near future, Skyroot Aerospace aims to further scale its operations, contributing significantly to India's commercial space ambitions. The company's achievements underscore the growing potential of the private sector to innovate and drive progress in space exploration and commercialization, establishing India as a significant contender in the global launch services market.
