This paper considers a low-cost approach to a manned Mars mission, commencing with the gradual development of the necessary nuclear electric propulsion capability through its application to challenging planetary objectives. To minimise cost, it is proposed that the Mars mission should utilise as much existing hardware as possible, thereby ensuring that new and costly heavy-lift launch vehicles are not required. It is shown that existing gridded ion thrusters, with performance envelopes extended to provide a specific impulse of about 7000 s, are capable of undertaking the proposed 1 MW mission.
