From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Most of these kinds of spacecraftpropulsion systems work by electrically expelling propellant (reaction mass) at high speed, but electrodynamic tethers work by interacting with a planet's magnetic field. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Such reactions open the possibility for triggering a significant number of secondary fission reactions in a subcritical mass, and may potentially be useful for spacecraftpropulsion. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Ion thrusters are not the most prospective type of electrically powered spacecraftpropulsion (although in practice they have worked out more than others).
