I guess those of us who have been with NASA kind of understand the tremendous excitement and thrills and celebrations and national pride that went with the Apollo program is just something you're not going to create again, probably until we go to Mars.

The first plane ride was in a homemade glider my buddy and I built. Unfortunately we didn't get more than four feet off the ground, because it crashed.

We wanted to be in great shape, we wanted to be able to cope with zero gravity, we wanted to be able to cope with accelerations and decelerations and so on. So all of us trained so that we were probably in the best physical condition we had ever been in up until that point.

I didn't mind studying. Obviously math and the physical science subjects interested me more than some of the more artistic subjects, but I think I was a pretty good student.

And I think that still is true of this business - which is basically research and development - that you probably spend more time in planning and training and designing for things to go wrong, and how you cope with them, than you do for things to go right.

The suit was so clumsy, being pressurized, it was impossible to get two hands comfortably on the handle and it's impossible to make any kind of a turn. It was kind of a one-handed chili-dip.

Whether you are an astronomer or a life scientist, geophysicist, or a pilot, you've got to be there because you believe you are good in your field, and you can contribute, not because you are going to get a lot of fame or whatever when you get back.
