Debugging from 15 billion miles away. Incredible!

The team discovered that a single chip responsible for storing a portion of the FDS memory — including some of the FDS computer’s software code — isn’t working. The loss of that code rendered the science and engineering data unusable. Unable to repair the chip, the team decided to place the affected code elsewhere in the FDS memory. But no single location is large enough to hold the section of code in its entirety. So they devised a plan to divide the affected code into sections and store those sections in different places in the FDS.
