Galileo's orbital tour consists of 11 different elliptical orbits around Jupiter. Each orbit (except one) includes a close flyby and gravity assist of one of the Galilean moons (Ganymede, Callisto or Europa) near the inner (Jupiter) end of the orbit. Distant scientific encounters with additional satellites are scheduled for a number of orbits, and the spacecraft will observe Io at medium range on every orbit.
The next satellite flyby will occur on September 17, 1997 when Galileo flies by Callisto. This encounter is referred to as Callisto 10 since it is on the tenth orbit of the 11 orbit tour. Careful targeting allows each flyby to direct the spacecraft on to its next satellite encounter and the spacecraft's next orbit around Jupiter. During the orbital tour, Galileo will fly by Ganymede four times, Callisto three, and Europa three.
