Systems are explored in regard to systems analyses and mission profiles that arise as result of recently acquired abilities to economically compute low-thrust and mixed high- and low-thrust trajectories; using vehicle system mass required on Earth parking orbit as optimizing criterion, round-trip missions to Mars in 1980 are considered with variations in propulsion modes and probable power output (power-system reliability), and with trajectory shaping; effects of mixed high-thrust and low-thrust operation are discussed as well as influence of power-system available power profile, maintenance, and reliability.
