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 bil - Space Daily

A single failed memory chip corrupted about 3% of Voyager 1's flight data subsystem in November 2023. Engineers relocated the affected 1970s code around the damage, sent the fix across 24 billion km, and got readable data back on 20 April 2024 after a 45-hour…

In late 2023, Voyager 1 stopped making sense. The spacecraft was still transmitting from interstellar space, but the data coming back was unreadable, a repeating pattern with no usable information in… [+3857 chars]
