The Galileo mission to Jupiter utilizes change of velocity earth gravity assist trajectories which leave earth in 1985 on 2-year orbits, have maneuvers of approximately 500 m/sec near aphelion, and then use earth flybys to send the spacecraft to Jupiter. It was noted that in Nov. 1985, one family of these trajectories passes fairly close to Halleys comet near its preperihelion node. It is shown that an arbitrarily close flyby of Halley can be added to these trajectories for about a 500 m/sec increase in the aphelion maneuver. Optimal trajectory design and mission performance as a function of launch vehicle capability are discussed in detail.
