Figure 4.19 ZY field line tracing of the magnetic field in the region of Ganymede for the G2 encounter. The coordinates are given in the aberrated frame which is defined by a rotation about the GSII x axis by an angle of 10º, and then a rotation about the new z axis by -33º. The projection of the trajectory of Galileo is shown by the line with open circles.  The first circle represents the position of Galileo at 18:40:00 with each consecutive circle separated by 5 minutes in time.

QUICK FACTS

Manufacturer: The Galileo Spacecraft was manufactured by the Jet Propulsion Laboratory, Messerschmitt-Bölkow-Blohm, General Electric, and the Hughes Aircraft Company.

Mission Duration: Galileo was planned to have a mission duration of around 8 years, but was kept in operation for 13 years, 11 months, and 3 days, until it was destroyed in a controlled impact with Jupiter on September 21, 2003.

Destination: Galileo's destination was Jupiter and its moons, which it orbitted for 7 years, 9 months, and 13 days.
