It's got to be possible to launch some in space now and have them go faster than voyager 2, so that the outside can be explored faster?
Because that part is a side benefit not worth launching for, and the main motivation (grand tour of the outer planets) for the Voyagers relied on a once-in-175-years alignment of the planets.
But maybe we’ll have nice probes ready to launch in the 2150s next time the alignment happens.
