Bellatrix Aerospace

Bellatrix Aerospace is a Bengaluru-based in-space propulsion company founded in 2015 by Rohan M Ganapathy and Yashas Karanam, developing electric (Hall-effect and water-based microwave plasma) thrusters and high-performance green chemical propulsion to replace toxic hydrazine. Its Rudra green and Arka Hall-effect thrusters were demonstrated in orbit on ISRO's POEM platforms. The company is also building the Pushpak orbital transfer vehicle (OTV) for in-orbit satellite maneuvering.

Products & Services

Rudra

operational
green chemical propulsion

First Indian high-performance green propulsion system, a 1N thruster for spacecraft of 50-1,000 kg that replaces hydrazine. Space-tested on ISRO POEM-3 (Jan 2024); upgraded version on POEM-4 (Jan 2025). Co-developed with IISc.

Since 2024

Arka

operational
electric propulsion

Hall-effect thrusters optimized for extended life, designed for micro-satellites (50-500 kg). Demonstrated in space on ISRO POEM-3.

Jal

development
electric propulsion

Water-powered microwave plasma electric propulsion system.

Pushpak

development
orbital transfer vehicle

Multi-mission orbital transfer vehicle / orbital platform for precise satellite deployment and hosted payloads. NSIL signed a contract to integrate Pushpak into NSIL launch missions in October 2024.

Fingernail

development
nano satellite thruster

Nano-thruster, an engine smaller than a dime, targeting nano-satellite propulsion.

Key Challenges

Scaling annual manufacturing capacity to meet demand from domestic and international satellite constellations.Bringing the Pushpak OTV from development to first operational launch on schedule.Competing globally with established electric and green propulsion suppliers while qualifying multiple thruster technologies.
