Bellatrix Aerospace

Bellatrix Aerospace designs and manufactures satellite propulsion systems, offering both electric and green (non-toxic) chemical thruster product lines. Founded in 2015 and incubated at the Indian Institute of Science in Bengaluru, the company holds development contracts with the Indian Space Research Organisation (ISRO) and its commercial arm NSIL. Its Arka line of Hall effect thrusters spans 50 W to 5 kW, serving satellites from CubeSats to large GEO platforms. The Rudra green propulsion thrusters, available in 1 N, 5 N, and 100 N variants, provide a non-toxic alternative to hydrazine. Bellatrix also produces the Jal microwave plasma thruster, which uses water as propellant, and the Fingernail thruster for nano-satellites. The company operates Pushpak, an orbital transfer vehicle capable of carrying payloads up to 750 kg with a hybrid propulsion system delivering up to 7 km/s delta-v. In 2025, Bellatrix established a U.S. subsidiary headquartered in Delaware with plans for a domestic manufacturing facility to serve the American market.
