In late 2023, Voyager 1 began sending unreadable data from interstellar space. NASA engineers eventually traced the fault to corrupted memory in one of the probe’s computers, rewrote part of its 46-year-old software, transmitted the fix across more than 24 billion kilometres, and waited roughly 45 hours for confirmation that the patch had worked.
