a few questions about Voyager 1- Is it designed to withstand re-entry into an "earth-like" planet? It just seems like the odds are astronomically low that this thing would find its way to intelligent life. I understand that it makes sense to put some information about our existence on it, but it seems that worrying that someone will come hunt us down and take our resources is not even worth thinking about.
No, its extended mission was designed to measure energetic particles at large distances from the sun (plus a few other field sensors). That's it. The whole "golden record" thing is just a monument to ourselves.
