QUESTION:
  How will you benefit from the knowledge gained during the Io encounter 
 of Dec 1995 when you plan the coming (final) encounter(s) with Io? I 
 seem to recall the computer "hickups" due to radiation were 
 surprisingly few (or none)...
  
ANSWER from Ed Hirst on April 14, 1997:
There is not very much specific knowledge from the first Io encounter
    that can be used to plan the Io encounters at the end of the Galileo
    Europa Mission.  Perhaps the most important piece of information is
    the one you mention in your question, the fact that there were surprisingly
    no hickups in the main computer due to radiation.

    Having said that, the radiation data gathered during the encounter
    will make it possible to update the radiation models for Jupiter and
    will allow better estimates of the radiation doses that the spacecraft
    has been and will be absorbing through end of mission.  

    These estimates can then be used to determine whether certain parts
    will be more suseptible to failure or not.  That information can then
    be used to prepare the spacecraft in such a way that failure of those
    parts will not cause the spacecraft to be lost or cause it to stop 
    performing science observations.
