The Indian Space Research Organisation (ISRO) has achieved a significant milestone by successfully completing a 1,000-hour life test on its 300mN Stationary Plasma Thruster. This development is key for integrating the Electric Propulsion System in future ISRO satellites.
Set to replace traditional chemical propulsion systems, the electric thrusters promise considerable mass savings, thereby enhancing the transponder capacity in communication satellites. The thrusters, which use Xenon as a propellant, showcase at least six times the specific impulse of conventional systems, a crucial performance metric.
The rigorous testing, conducted at a full power level of 5.4kW in vacuum-simulated conditions, provided vital erosion data essential for predicting thruster lifespan and aiding satellite orbit management. These thrusters are slated for validation in the upcoming Technology Demonstration Satellite (TDS-01).
