I slept just floating in the middle of the flight deck, the upper deck of the space shuttle.

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.

Our future lies with today's kids and tomorrow's space exploration.

You know, I go around the country a lot.

You can picture pretty easily if there were a paying passenger aboard a rocket that failed, like Challenger failed. Certainly it would be a tragedy, and a tragedy for the company. They would have a hard time recovering from it.

So most astronauts are astronauts for a couple of years before they are assigned to a flight.

Weightless is a great equalizer.
