If you want a moment when Voyager felt “modern” again, 2013 is it. That was the year the mission transitioned from “planetary flyby relic” to “deep space weather station.” It’s a powerful reminder that NASA’s long-haul missions often reveal their biggest secrets not at launch, but decades later.
In 2013, Voyager 2 was still inside the heliosphere (~100 AU), but closing in. It would eventually cross into interstellar space in 2018.
NASA officially announced that Voyager 1 had entered interstellar space — a moment decades in the making. The evidence came from plasma wave data collected in late 2012 / early 2013, showing a dramatic jump in plasma density consistent with leaving the heliosphere. For context, Voyager 1 was about 122 AU from the Sun (that’s ~11 billion miles).
