MIT Researchers Develop Dual-Mode Propulsion System for Small Satellites

Researchers at the Massachusetts Institute of Technology have developed a dual-mode propulsion system that combines chemical thrusters with electrospray electric thrusters for use in small satellites. This new technology allows satellites to utilize the high-thrust capabilities of chemical propulsion for rapid maneuvers while employing the fuel efficiency of electric propulsion for long-term orbital adjustments.

The system integrates these two distinct methods into a single unit, addressing the limitations currently faced by small-scale spacecraft that typically rely on only one type of propulsion. By utilizing chemical thrust, the satellites can perform quick changes in velocity, while the electrospray component provides the precision required for delicate positioning and extended mission durations. This design aims to provide satellite operators with greater operational flexibility, allowing for both high-speed responses and sustained fuel conservation during flight.
