Curious, has Voyager 1 brought in any data in recent years that is scientifically meaningful? Not to put down the efforts of keeping it alive, I love that. Just wonder how much of its task is "done".
I can really recommend the documentary It's Quieter in the Twilight. It covers the flight-team operating Voyager, and shows in-depth what they and Voyager is doing.
From the article: “Voyager 1 still has two remaining operating science instruments — one that listens to plasma waves and one that measures magnetic fields. They are still working great, sending back data from a region of space no other human-made craft has ever explored. The team remains focused on keeping both Voyagers going for as long as possible.”
