Galileo Ganymede 7 Flyby Entry Timeline

Ganymede 7 Flyby was 05 April 1997

Galileo's third flyby of Ganymede, the largest of Jupiter's Galilean satellites, occurred on 05 April 1997 at 07:10 UTC. At that time, Galileo came about 3095 km from the surface of Ganymede (or about 3.1 Ganymede radii from its center). As measured to the center of Ganymede, this is 2.6 times farther away than Galileo came to Ganymede during its closest approach on its second orbit back in September 1996. During this time, observations will also be made of the Jovian magnetosphere as well as of the other satellites of Jupiter.

The following timeline is a list of different events which will occur beginning with the official start of the Ganymede 7 (the number actually refers to the Galileo orbit number) encounter and proceding until the last data from the encounter are played back. The times are given in Universal Time (UTC) of the event at the spacecraft.
