I was not the commander, I was a junior person, so once both were outside, I followed my leader, because we (NASA) had not put together detailed jobs of people outside. I believe it could have been improved. But it was very successful for what it was.

America can take man to the moon, and America can take men to Mars - and beyond.

I'm not in favor of just taking short-term isolated situations and depleting our resources to keep our climate just the way it is today.

For the future, primarily, we must educate people in science, engineering, technology and math.

I want to keep on the move, keep stimulated and challenged.

When we can demonstrate that we can take off horizontally and put something into orbit, then we can begin to talk about increasing the amount of payload. But to say, 'I'm going to do that and put people into orbit' is a real leap.

We need to have people up there who can communicate what it feels like, not just pilots and engineers.
