Spacecraft propulsion is used to change the velocity of spacecraft and artificial satellites, or in short, to provide delta-v.
This means that for maneuvering in space, a propulsion method that produces tiny accelerations but runs for a long time can produce the same impulse as a propulsion method that produces large accelerations for a short time.
The law of conservation of momentum means that in order for a propulsion method to change the momentum of a space craft it must change the momentum of something else as well.
