Bellatrix Microwave Plasma Thruster Render

Artist visualization of the Microwave Plasma Thruster (MPT) firing in deep space using water as propellant.

Bellatrix Aerospace focuses on what happens after a rocket reaches orbit. Founded in 2015 at the Indian Institute of Science (IISc) by Rohan M Ganapathy and Yashas Karanam, they specialize in in-space propulsion systems designed to make satellites highly maneuverable, efficient, and exceptionally eco-friendly.

Propelling the Future: Water as Fuel

One of Bellatrix's most globally significant innovations is their **Microwave Plasma Thruster (MPT)**. Traditional satellites use highly toxic, expensive chemical propellants like Hydrazine. The MPT literally uses water. The system converts liquid water into plasma using microwave energy to generate thrust. This drastically reduces mission costs, simplifies fueling protocols, and eliminates toxicity hazards.

⚛️ Propulsion Portfolio

Technology	Propellant	Use Case
MPT (Microwave Plasma)	Water / Green Propellants	Station keeping / Deep Space
Hall Effect Thruster	Xenon / Krypton	Large Satellites / ISRO Missions
Rudran (Green Propellant)	Non-toxic High Performance	Quick Maneuvering

Arka: The Space Taxi

Bellatrix is developing the **Arka Orbital Transfer Vehicle (OTV)**. Think of this as a space taxi. A large rocket (like ISRO's PSLV) drops the Arka OTV in a common orbit, and Arka then uses its advanced thrusters to deliver multiple small satellites to their precise, differing functional orbits. This "last-mile delivery" service is essential for the future of megaconstellations.
