As of now, the usable data returned so far relates to how the spacecraft’s engineering systems are working. The team plans more software repair work in the next several weeks so that Voyager 1 can send valuable science data about the outer reaches of the solar system that is readable once again. As of now, Voyager 2 is still operating normally.

This illustration provided by NASA depicts Voyager 1. The most distant spacecraft from Earth stopped sending back understandable data in November 2023. Flight controllers traced the blank communication to a bad computer chip and rearranged the spacecraft’s coding to work around the trouble.

NASA said Voyager 1, the farthest spacecraft from Earth, is finally sending readable data for the first time in five months after a computer chip became corrupted.
