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 first of these satellite swingbys is with Ganymede was successfully performed on June 27, 1996 (also referred to as Ganymede 1). 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.
