The ST-25 from Space Electric Thruster Systems (SETS) is a Hall-Effect thruster that has a thrust of 5-11 mN. It has a mass of 0.95 kg and a specific impulse of 1000-1400 s. This compact hall-effect thruster has an input power of 100-200 W and a thrust efficiency of 30%. It has a permanent magnet in the central core and eliminates the shortcomings of low-power thrusters. This spacecraft thruster works on inert gases such as Xenon (Xe) and Krypton (Kr). It measures 60 x 107 x 91.5 mm and is ideal for satellite constellations.
