50 years on, there's still nothing like the Voyager probes

That was a sad thing that they turned off, but it was a marvelous job.

But you just think of all the trade-offs we had to do.

I wanted to see atmospheric features.

The geologists wanted the surface features.

Other people wanted elements of the power systems as well.

So it was a mission of trade-offs.

It was a mission of using incredible talent.

But one of the most important things that came out of Voyager which is doing what we're doing now, sharing the results.

We had terrifically good press conferences every morning.

We met regularly with the press.

We did television regularly so people kept up to date.

I always thought that the taxpayer who had paid for this mission, and it cost $800 million, well, 8 cents per American per year, which is pretty good in value for money, we should share the results with them.

And to this day, I go around giving talks to people, people ask me fundamental questions, and I'm delighted to be able to share the results with them.

That's great.
