The Most Distant Planetary Probes to leave Earth

Humans have pushed the frontiers of exploration in space by sending probes to the edge of our Solar System and beyond. Just how far have we traveled, and what have we seen along the way? How do we keep in touch with the most distant objects, and what is left to learn from these probes? 

In the June 2025 episode of the Translunar Podcast, I discuss the very old Pioneer and Voyager missions past Jupiter, Saturn, Uranus and Neptune, as well as the New Horizons mission past Pluto and into the Kuiper Belt.
