actually i was just reading on the SciAm blogs about this, and learned a bit more about the edge of our solar system (and how the scientists involved in this effort are tracking progress).
key comment: 'Decker and his colleagues conclude from the plasma measurements “that Voyager 1 is not at present close to the heliopause, at least in the form that it has been envisioned up to now.” '
just an interesting addendum to the story that NPR glossed over.
