> Through their investigation, Voyager's ground team discovered a single chip responsible for storing a portion of the FDS memory stopped working, probably due to either a cosmic ray hit or a failure of aging hardware. This affected some of the computer's software code. IIRC, the Voyagers have redundant FDS computers, but I believe the non-active ones have been considered bad for decades. Now that they're seeing hardware failures on the active one, I wonder if they're evaluating the problems in the inactive ones to determine if they might actually be in better shape.
