NASA Fixed The Glitch That Caused Voyager 1 To Send Incorrect Data Back To Earth 

The Voyager 1 team solved the problem with sending anomalous telemetry that came from the probe for several months. It turned out that the cause of the failure was a faulty on-board computer, which was mistakenly assigned the operation of sending data. Now the problem is fixed, according to the NASA website.

Suzanne Dodd, manager of the Voyager project, said the engineers decided to try the safest solution to the problem: they ordered AACS to resume sending data to the correct computer.

Engineers don’t yet know why AACS started routing telemetry data to the wrong computer, but it likely received an erroneous command generated by another onboard computer. If it is, then it indicates that there is a failure somewhere else. The team will continue to look for the underlying problem, but they do not think it is a threat to the long-term operation of Voyager 1.

“We will do a full analysis of the AACS memory and examine everything it did. This will help us try to diagnose the issue that caused the telemetry errors in the first place. So we’re pretty optimistic, but we still need to investigate,” Dodd said.
