A new type of rocket engine propels a spacecraft by taking advantage of the physical mechanism that accelerates solar flares. The engine would apply magnetic fields to force particles of electrically charged gas, or plasma, to shoot out the back of a rocket with high velocity, causing forward momentum. The new rocket is scalable from short to long range missions, ranging from solar powered drone delivery from LEO to the moon, as well as nuclear powered interplanetary space exploration. The engine can use a wide variety of gases as propellant without sacrificing performance, allowing it to be refueled with gases extracted from asteroids or the lunar surface.
