Astrophel Aerospace to Test India’s First Privately Built Reusable Rocket Prototype on Independence Day 2026

Pune-based space tech startup Astrophel Aerospace, which has developed an in-house portfolio of ‘Made-in-India’ propulsion and cryogenic subsystems, today announced the upcoming test flight of its reusable suborbital rocket, targeting 15th August, 2026.

Designed as a vertical takeoff and vertical landing (VTVL) test prototype, a successful test not only represents a critical milestone towards the development of a fully operational and commercially viable reusable launch vehicle in India, but also as a flight-relevant validation platform for Astrophel’s cryogenic subsystems and components.

The 3-metre long prototype, also known as a hopper, weighs approximately 200kg, currently being designed, manufactured and assembled at Astrophel’s Pune facility. The space tech startup also recently developed high-performance cryogenic control valves, marking another key milestone in India’s private aerospace component manufacturing ecosystem. The valves are part of Astrophel’s broader portfolio of propulsion and cryogenic sub-systems, including turbopumps, vacuum-insulated cryogenic storage tanks and high-speed precision linear actuators.

We expect the upcoming test to mark one of the first instances of a privately developed reusable rocket prototype that’s been designed, manufactured and tested entirely from within India, said Co-founder and CEO, Suyash Bafna

Astrophel Aerospace was one of a handful of space tech startups to successfully conduct a cryogenic engine test just three years ago on 15th August 2023, raising more than USD 800,000 last year. By vertically integrating critical sub-systems, the startup is demonstrating a tightly integrated hardware ecosystem that enables faster development cycles, improved performance control and seamless integration across allied industries such as aerospace, defense, oil & gas and emerging energy applications such as green hydrogen.

Our in-house design and manufacturing approach borrows inspiration from automotive best practices and we’ll be able to develop subsystems at approximately 40% of the cost compared to global players, added Cofounder and COO, Immanuel Louis.

India’s space tech startups today rely heavily on imported subsystems and components. Astrophel aims to address this gap by developing and validating critical hardware in-house, while also building revenue through component sales and licensing partnerships. The approach enables the company to de-risk the path to orbit while making high-performance propulsion and cryogenic systems more accessible to a broader range of launch partners and customers.

Satellite operators today rely on rideshare programs that face multiple delays due to limited availability and scheduling constraints, while it is predicted that over 70,000 low Earth orbit (LEO) satellites will be launched over the next five years, as per Goldman Sachs Research. Demand for faster and more flexible launch solutions is set to grow exponentially with reusability emerging as a critical capability driving the future of accessibility to cost effective launch services.

Astrophel Aerospace, a Pune-based spacetech startup, is currently testing and characterising its indigenously developed cryogenic pump at ISRO facilities. Once successfully validated, the cryo-pump will be upgraded into a fully-fledged turbopump for integration into the startup's rocket engine, the Astra C1, by late 2026. The technical milestone positions Astrophel as one of the first private Indian space startups to develop an in-house cryo-pump.

Astrophel is also in the process of signing an MoU with a US-based partner and is actively exploring additional global collaborations, for export commercialisation at the sub-component level to service rising demand in the global space sector and industries such as oil and gas, which handle cryogenic fuels. Unlike other technical approaches, a turbopump draws power directly from the engine itself, eliminating the need for external batteries, making it a more sustainable long-term solution for space engine reusability and cost-efficient launches across all segments.

“This milestone is a testament to how India can indigenously develop advanced propulsion technologies at a fraction of global costs,” said Suyash Bafna, Co-Founder of Astrophel Aerospace. “ISRO’s certification will validate not just our pump, but India’s ability to innovate world-class space hardware with global export opportunities”, he added.

What began as fifty-plus separate, precisely engineered components comes together into a cryo-pump system that spins at 25,000 RPM, delivering cryogenic fuel that will power both Astrophel’s first and second-stage rocket engines. For context, at least 8-9 turbopumps are required just during the first-stage liftoff of an SSLV.

The announcement comes as India sets its sight on growing the space economy from $8.4 billion in 2022 to $44 billion by 2033, capturing 8% of the global market. With more than 250 startups entering the sector, propulsion milestones like Astrophel’s cryo-pump are vital to achieving this vision. “This milestone represents the culmination of years of frugal engineering and is a stepping stone toward India’s first privately developed gas generator cycle,” added Immanuel Louis, Co-Founder, Astrophel Aerospace.

Though the size of a one-litre bottle, the cryo-pump is powerful enough to generate 100 to 150 horsepower, equivalent to that of a family car, which will be scaled up to deliver 500 to 600 horsepower (turbopump) for larger launch vehicles. Acting as the “heart of the rocket,” a turbopump feeds cryogenic fuel into the engine at high pressure, ensuring efficient thrust control and lower material costs. Astrophel’s approach differs from other startups pursuing 3D-printed, electric pumps. Adopting lean manufacturing principles from the auto sector ensures cost efficiency, rapid assembly, and scalable production.
