I don't follow...have we not visited all the planets? Perhaps he means we have flown past them all?

  Pluto = dwarf planet, so it's irrelevant to statement. Also, we certainly haven't visited all dwarf planets.

    The probe was launched before Pluto was re-classified as a dwarf planet. Either way, this is an immense achievement in both will and engineering.
