During the Callisto flyby, enhancements in NASA's Deep Space Network were implemented to permit a higher data return rate from Galileo which, coupled with other improvements, raised it from a mere 10 bps to close to 1,000 bps. This change should permit the project to accomplish 70% of the original science goals at Jupiter.
The following timeline is a list of different events which will occur beginning with the official start of the Callisto 3 (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.
