Weightless is a great equalizer.

When the space shuttle's engines cut off, and you're finally in space, in orbit, weightless... I remember unstrapping from my seat, floating over to the window, and that's when I got my first view of Earth. Just a spectacular view, and a chance to see our planet as a planet.

I did not come to NASA to make history.

The space shuttle is a better and safer rocket than it was before the Challenger accident.

The view of earth is spectacular from space. Most people imagine that when astronauts look out the window of the shuttle they see the whole earth like that big blue marble that was made famous by the flights that went to the moon. But the shuttle is much, much closer than those astronauts were. So we don't see the whole planet, the whole ball at once, we just see parts of it.

If they asked me if I wanted to go into space tomorrow, I'd do it in a heartbeat. On the other hand, if they asked me if I wanted to go into training for three years and then go into space again, I'd probably say no.

I love the John Glenn model... I may call NASA in 25 years or so, and see if they'd like to send me to Mars.
