Ionic propulsion, as it is now envisioned, is restricted to applications involving extremely low thrust. It is therefore necessary that an ion rocket be given a satellite velocity by chemical means. Methods for the determination of optimum trajectory and optimum propulsion system for a specific mission are outlined and illustrated by example calculations: 100 kg initial gross weight from a 500 km orbit to the altitude of the moon in six months, and 300 kb initial gross weight from escape velocity to the orbit of Venus in one year. The advantages of an overall system consideration are demonstrated by this treatment. (Author)
