  More than 30 years have passed since the Voyager 2 fly-bys of Uranus and
Neptune. I discuss a range of lessons learned from Voyager, broadly grouped
into process, planning, and people. In terms of process, we must be open to new
concepts: reliance on existing instrument technologies, propulsion systems, and
operational modes is inherently limiting. I cite examples during recent decades
that could open new vistas in exploration of the deep outer Solar System.
Planning is crucial: mission gaps that last over three decades leave much scope
for evolution both in mission development and in the targets themselves. I
touch only briefly on planetary science, as that is covered in other papers in
this issue, but the role of the decadal surveys will be examined in this
section. I also sketch out how coordination of distinct and divergent
international planning timelines yields both challenges and opportunity.
Finally, I turn to people: with generational-length gaps between missions,
continuity in knowledge and skills requires careful attention to people. The
youngest participants in the Voyager missions (myself included) now approach
retirement. We share here ideas for preparing the next generation of voyagers.
