Associated Propellants
  • Electric/Teflon The many versions of electric engines use electric or magnetic fields to accelerate ionized elements to high velocity, creating thrust. The power source can be a nuclear reactor or thermal-electric generator, or solar panels. Teflon was introduced in the late 1990's as the solid fuel heated electrically to provide a completely solid-state rocket system for spacecraft orientation with no moving parts. More...
