NASA required a rocket thruster able to produce a number of pulses at high specific impulse at a relatively low voltage (~300 to 400V). The key problem was that existing propellants for liquid-fueled pulsed plasma thrusters (LPPTs) required high voltages to ablate and accelerate the propellant. The Green Electric Monopropellant (GEM)-fueled Pulsed Plasma Thruster (PPT) is a rocket thruster that is able to produce a number of pulses at high specific impulse at a relatively low voltage (~300 to 400V).
