  "title": "NASA’s Voyager 1 Resumes Sending Engineering Updates to Earth – Voyager",
  "note": "**I absolutely adore this story!** The idea that this NASA team was able to revive Voyager 1 after a chip on it failed while it is hurtling in outer space is just **fabulous**!\n\n> The [team discovered](https://blogs.nasa.gov/voyager/2024/04/04/engineers-pinpoint-cause-of-voyager-1-issue-are-working-on-solution/) 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.\n> \n> So they devised a plan to divide the affected code into sections and store those sections in different places in the FDS. To make this plan work, they also needed to adjust those code sections to ensure, for example, that they all still function as a whole. Any references to the location of that code in other parts of the FDS memory needed to be updated as well.\n\nSo, this is some pretty low level addressing stuff going on. And let me tell you, the idea that you mess this up and point at the wrong memory locations is the kind of stuff that would make any developer anxious. Now imagine doing that work on a spacecraft that is so far away it takes over **22 hours** for the signals to reach it!\n\nI love the picture too. Those are some deservedly happy technologists. This group deserves some medal. Send them a POAP!",
