**7. Conclusions**

So near the end of its 40 plus year mission Voyager has crossed the heliopause and sampled the interstellar energetic particle background for the 1st time. No one who has been involved in this mission from the beginning would have dreamt that this was possible. The goal of this chapter has been to attempt to convey some of the remarkable features of this data. Perhaps Voyager has saved its best for last, but only a few of us who could understand it are still around. The mission did not end with pictures of the planets but perhaps in the experience of the limits of humans in the eternal universe.
