Galileo - Countdown to Europa 11


Galileo's Orbital Tour

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.

Galileo had a close encounter of Europa on November 6, 1997. This encounter is referred to as Europa 11 since it is on the eleventh 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. Europa 11 is the final orbit for Galileo during its primary mission, and after playback of the data collected during this orbit, will then proceed with the Galileo Europa Mission.
