Advanced Ion Propulsion Technology for Solar System Exploration

The use of ion propulsion for deep-space missions is becoming a reality with the flight next year of the ion propelled Ner Millenium Deep Space 1 Spacecraft. This event is already stimulating the call for improved ion propulsion technologies, a trend which is expected to continue. This paper describes the examination of advanced solar electric propulsion technologies to determine their potential benefits for projeted near and mid-term solar system exploration missions.
