The rest of the probe also appeared healthy as it continued to gather and return science data.<\/p>\n\n\n\n<p>The team has since located the source of the garbled information: The AACS had started sending the telemetry data through an onboard computer known to have stopped working years ago, and the computer corrupted the information.<\/p>\n\n\n\n<p>Suzanne Dodd, Voyager\u2019s project manager, said that when they suspected this was the issue, they opted to try a low-risk solution: commanding the AACS to resume sending the data to the right computer.<\/p>\n\n\n\n<p>Engineers don\u2019t yet know why the AACS started routing telemetry data to the incorrect computer, but it likely received a faulty command generated by another onboard computer. If that\u2019s the case, it would indicate there is an issue somewhere else on the spacecraft. The team will continue to search for that underlying issue, but they don\u2019t think it is a threat to the long-term health of Voyager 1.  <\/p>\n\n\n\n<p>\u201cWe\u2019re happy to have the telemetry back,\u201d said Dodd. \u201cWe\u2019ll do a full memory readout of the AACS and look at everything it\u2019s been doing. That will help us try to diagnose the problem that caused the telemetry issue in the first place. So we\u2019re cautiously optimistic, but we still have more investigating to do.\u201d<\/p>\n\n\n\n<p>Voyager 1 and Voyager 2 have been <a href=\"https:\/\/www.jpl.nasa.gov\/news\/voyager-nasas-longest-lived-mission-logs-45-years-in-space\" rel=\"noopener\">exploring our solar system for 45 years<\/a>.
