Abstract :
The Galileo spacecraft has been subjected to the harsh charged-particle environment around Jupiter since 1995. As the spacecraft has far exceeded the radiation dose for which it was designed, there have been a number of system failures attributable to radiation effects. This paper is a summary of those failures, the evidence for their connection to radiation related causes, and the associated fixes the Galileo flight team has implemented.
