Two spacecraft are conducting a low thrust spiral escape from Ceres orbit (6.26325 imes 10^(10)(m^(3))/(s^(2)) ). Spacecraft A is a conventional "Dawn-type" spacecraft with an initial mass of 800 kg. The thruster for Spacecraft A provides a specific impulse of 4190s and a jet kinetic output power of 700W around Ceres. The other spacecraft, Spacecraft B, is a futuristic CubeSat with an initial mass of 10.5 kg, and an EP system that produces 16,000 seconds of I_(SP) with a jet kinetic output power of 200W.
