Plume of the Rotating Magnetic Field Thruster: This is a 10 s exposure image of a new type of in-space propulsion device, a rotating magnetic field thruster, operating on a xenon plasma. This technology was developed and researched through an AFOSR Young Investigator Program through the Space Propulsion and Power portfolio. It offers several potential advantages including the ability to throttle while maintaining high efficiency and the ability to operate on non- traditional propellants. We took this long exposure image in order to examine qualitatively the structure of the exhaust generated by this thruster. The plume shows evidence of plasma being expelled downstream with a high degree of divergence. In practice, this thruster is pulsed such that the propellant is expelled from the device in bursts at a rate of 100 times per second. This image represents the average of over 5000 pulses.
