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.

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.

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

If it wasn't for the women's movement, I wouldn't be where I am today.

I find myself looking around for other new, interesting opportunities to dive into.

It was a real honor for me to get to be the first woman astronaut. I think it's really important that young girls that are growing up today can see that women can be astronauts too. There have actually been a lot of women, who are astronauts, that that's a career that's open to them.

It takes a few years to prepare for a space mission.
