The ability of the humans to not only function in space but be very functional when they arrive at their destination, those are the kinds of things we're learning from the science. Fuel transfer technologies and all the things we can learn about the space environment are all valuable to us for pressing on out.

When the guys come back in from the spacewalk, there really is a distinct smell of space; it's something I will never forget.

One of the things I do know is we know very little about our universe. Even though we think we know a lot, and we do know a lot more than we used to, we have a lot to learn about our universe.

I think someday, out in space, perhaps, some people might be able to grow some of their own food or hopefully on another planet.

I felt that as long as we were being honest, and that we didn't bend the truth to accomplish another goal, to be entertaining or to be a happy ending, I was confident that we'd be able to tell the story the way it happened.

Failure is a part of success.

People who have the drive to achieve spend most of their time on what brings them the most tangible, immediate sense of success. Investments in our family only pay off in the very long term.

Your fame and your success moves much more rapidly than your ability to fund it.
