The Arka Green Propulsion system is a high-performance chemical thruster series developed by Dawn Aerospace as an alternative to traditional hydrazine-based systems. It utilizes a proprietary non-toxic propellant combination, primarily nitrous oxide and a fuel blend, which allows for simplified handling and lower ground support costs. The technology stems from the manufacturer's experience in building launch vehicles and satellite sub-systems, aiming to provide a 'turnkey' propulsion solution for the small satellite market. This system is sold both as a standalone thruster unit and as part of a fully integrated propulsion module, including tanks and control electronics. It is marketed toward commercial satellite operators and government space agencies seeking to comply with tightening environmental regulations regarding hazardous materials. The hardware is currently in active service, having been selected for various CubeSat and SmallSat missions, including those for commercial Earth observation and technology demonstration constellations. Potential buyers should evaluate the specific impulse trade-offs when switching from monopropellant hydrazine to this nitrous-based architecture. The Aerospace Garage desk would seek to verify the cumulative on-orbit firing hours across the different thruster sizes (ranging from 0.5N to 20N) to confirm long-term catalyst stability. We would also scrutinise the thermal management requirements, as nitrous-based systems can have different heat profiles compared to legacy toxic propellants.
