QUESTION:
Will there be another chance for an Io flyby?  Perhaps at the end of the
mission?

ANSWER from Leslie Tamppari on January 10, 1996:
There is some discussion about another chance for an Io flyby at
the end of the nominal mission or perhaps during a potential
extended mission.  This is one topic that will be discussed
by the Project Science Group at a meeting at the end of
January.  Many people feel that Io is so important that we should
flyby again, but there are some risks.  One risk is the 
extreme radiation environment at Io's distance from Jupiter.
Our spacecraft was designed to go in that close only once, and
another time may result in severe damage to the computer
and other systems on board the spacecraft.  Another open issue
is whether or not we have enough propellant on board to adjust
the orbit to go in that close to Io again.  Still another is
whether or not, given the uncertainties mentioned above, it
is worth possibly giving up the last two nominal orbits to
achieve another Io flyby, or to bet on extended mission funding.
We may know how this issue will be resolved in the next 
several months after more discussion and analysis.
