The pressure suit helps if something goes wrong during launch or re-entry - astronauts have a way to parachute off the shuttle. The suits protect you from loss of pressure in case of emergency.

I suggest taking the high road and have a little sence of humour and let things roll off your back. I think that's very important.

The food isn't too bad. It's very different from the food that the astronauts ate in the very early days of the space program.

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.

Suppose you came across a woman lying on the street with an elephant sitting on her chest. You notice she is short of breath. Shortness of breath can be a symptom of heart problems. In her case, the much more likely cause is the elephant on her chest. For a long time, society put obstacles in the way of women who wanted to enter the sciences. That is the elephant. Until the playing field has veen leveled and lingering stereotypes are gone, you can't even ask the question.

Anything from making a mistake on an experiment that would ruin some scientist on earth's experiment - career, potentially - to doing something wrong with the satellite that a country was depending on for its communications, to making some mistake that could actually cost you and the crew either a mission or your lives. So there is a lot of pressure that's put on every astronaut to just make sure that he or she understands exactly what to do, exactly when to do it, and is trained and prepared to carry it out.

You know, I go around the country a lot.
