Traditional satellite propulsion systems, particularly those used in small satellites like CubeSats, often encounter limitations in terms of efficiency and lifespan. These conventional systems, crucial for controlling and maneuvering satellites, struggle with generating enough thrust and maintaining it over extended periods due to constraints in propellant use and power management.
Researchers at George Washington University have introduced a novel modular micro-cathode arc thruster system with an innovative design that significantly enhances thrust efficiency and extends operational lifespan. The system uses a modular approach, allowing for the integration of multiple thrusters within a single satellite. This modularity and the improved design of the thrusters contribute to a more efficient and sustainable solution for satellite propulsion. This technology can enhance the maneuverability and operational capabilities of satellites, particularly beneficial for small satellite constellations and long-duration space missions.
