Ganymede 2 Timeline

All times are SCET (Spacecraft Event Time) in PDT (PDT = UTC - 7 hours) and PST (PST = UTC - 8 hours). Take a look at the Galileo Acronyms List for explanations of the acronyms used in this timeline.

Note: This timeline was updated on August 20, 1996.

*   Denotes transition from PDT to PST
**  Closest approach distances are with respect to the center 
    of the target body.
*** PPR observations, shown as originally planned, have been 
    removed from the encounter due to ongoing anomaly investigations.
