Celestial Aerospace, founded by Shreyans Jain, is an Indian deep-tech aerospace startup recognised by DPIIT developing an alternative launch architecture aimed at making access to space cleaner, more efficient and scalable. The company is focused on rethinking the most inefficient phase of rocket launches by using a balloon-assisted system to lift rockets to high altitude before engine ignition, significantly reducing fuel burn, drag and early-stage losses.
Celestial Aerospace is currently advancing its first prototype test vehicle, designed to validate the launch sequence, separation mechanisms and real-world flight behaviour of its architecture. The company has completed extensive simulation and analytical work across propulsion, aerodynamics and structures and is now progressing toward physical component testing and integrated system development.
The startup has filed patent applications in India, with international protection under the PCT, to secure its core launch architecture. Its engineering team includes specialists across propulsion, aerodynamics, structures and simulation, combining hands-on experimentation with first-principles design to simplify traditionally complex launch systems rather than relying on brute-force scaling.
In the long term, Celestial Aerospace plans to commercialize a small orbital launch vehicle capable of deploying satellite payloads, positioning itself within the rapidly growing global demand for flexible, efficient access to orbit. The company’s broader vision extends beyond Earth, with development on scalable systems intended to support future interplanetary transportation in a more sustainable and resource-efficient manner.
By focusing on architectural simplification, disciplined testing and step-by-step validation, Celestial Aerospace aims to become a foundational player in India’s private space ecosystem. Building launch infrastructure designed not just for today’s satellite market, but for the next era of space-based industries.
