I happened to be in Africa shortly after the landing on the moon, and the people in Africa told me they were dancing in the streets when we landed on the moon. So it was a joy for everyone, and uplifting the human spirit in a certain kind of sense. This is one of just human aspirations. Now, is it economical to do that? Well, it’s economical in the same sense maybe that music is. Music is uplifting, it doesn’t buy us anything. It’s something that humans enjoy, they like, it’s a human aspiration, human enjoyment. It’s culture. So traveling into space is something that most humans find fascinating and interesting, they’re willing to devote some time to it, and have thought about it. And I think it’s more for that reason that we are likely to — and the human race will continue to — explore space. It’s not just for science. There’s science, but there’s adventure, there’s a frontier, there’s just general human aspirations. And so I believe in a manned space program, as well as an instrumental program. Both are very expensive, we need to examine them well, and I have spent a good deal of time advising on the space program too. I think we need to think about them very carefully as to what’s the best thing to do. The economical ways of doing it, the new techniques, how to do it well and safely. But I believe in the long run, this is one of the human aspirations, and we will fulfill it in some way or the other, and I hope we can fulfill it well.
