I've seen this article mentioned on several sites. The title is terrible, misleading clickbait that seem to indicate that the Voyager 1 has been unresponsive for 37 years. What nonsense! This is really about how NASA found they could use a set of thrusters that had been idle for 37 years. A much better discussion can be found at this NASA page:
