This paper discusses the trade-offs involved in the design of a Pluto flyby mission using a low-mass spacecraft, the objective of which is the first-ever reconnaissance of the Pluto/Charon system. The analyses include launch opportunity/trajectory identification/launch vehicle trades, flight time vs net spacecraft mass trades, and flyby targeting considerations. Two mission concepts currently under development are discussed. One concept involves an 83 kg dry spacecraft which uses a direct trajectory and a Titan IV/Centaur (with two solid rocket motor upper stages) to reach Pluto in 7 years. The other design is a 316 kg dry spacecraft which uses a 3+Delta VEJGA trajectory and a Delta II (7925) to arrive at Pluto in 13.6 years.
