You really ought to take more interest in what’s going on, Voyager is still working, still sending data back, and it’s gone beyond the edge of the solar system, in fact it’s re-defined where the solar system ends, and interstellar space begins.
Rosetta isn’t that whizzy, really, and a radio signal travels at the speed of light, it takes eight minutes for light and radio to travel from the sun to us, ten minutes from Rosetta to us, four and a half years to the nearest neighbour star, Alpha Centauri.
Voyager 1 is now 19,038,292,158km from Earth, 18,952,241,706km from the sun, and counting, the roundtrip light time from the sun is 35:16:49,
Voyager 2 15,653,474,104km from Earth, 15,534,355,362km from the Sun, 29:00:28 light time. And counting.
Voyager 1’s total elapsed planetary and interstellar mission is currently 36 years, four months and fifteen days,
Voyager 2’s total elapsed planetary and interstellar mission is currently 36 years and 5 months.
And you think Rosetta is pushing the envelope?
And before the question arises about how they manage to get enough power to keep running, when they’re that far from the sun, both Voyagers are nuclear powered, but their power plants are on limited time.
