Galileo has received approval for a two-year follow-on mission, called the Galileo Europa (GEM). A three-phase tour has been designed for GEM that includes eight Europa encounters, four Callisto flybys, and two Io encounters to end the GEM in Decemger 1999. Although science desires for the satallite encountes were of primary importance to the tour design, the flyby conditions were also necessarily selected on the basis of the gravity assist they contributed to the trajectory. The tour design was heavily influenced by the requirement to return to Io, since the radiation exposure that acompanies such a flyby may serverely degrade the health of the spacecraft.
