Advantages of Earth-Mars-Earth (EME) trajectories over more conventional Mars trajectories are described and characteristics of favorable EME trajectories for spacecraft launched during 1970 decade identified; results of analysis of major engineering problems show that EME missions of ballistic and impulsive type (i.e., in which velocity correction is required at Mars) are feasible with present-day launch vehicles during all Mars launch opportunities in 1970s; total mission times vary between 370 and 800 days; flyby altitudes are attractive for scientific experiments at Mars; EME missions allow transmission of several hundred times more data back to Earth than can be obtained from other Mars flyby or orbiter spacecraft.
