The money would be the hold-up. I think if money weren’t an issue then a modern rethinking of a Voyager style satellite could get made to go crazy fast. In like 5 years we may even be able to use a starship to lift up something massive. Imagine a satellite that’s just absolutely huge with like 80% of its weight being nothing but nuclear reactors and ion drives.
I mean, Voyager has left our solar system in <50 years. It’s definitely not “generations” to get there. As long as there’s a river that flows up to the moon, the Vikings would have probably gone to raid it.
