electric thruster efficiency

Electric thruster efficiency measures how well the device converts electrical energy into useful thrust to propel a spacecraft. It compares the power used from the energy source (like solar panels) to the actual thrust generated. Higher efficiency means more of the electrical power is turned into motion, which allows for longer or faster journeys with less energy loss. Efficient thrusters are important for space missions because they save power, extend mission life, and reduce costs. In essence, efficiency indicates how effectively an electric thruster uses its energy to produce the desired pushing force in space.
