Even though NASA tries to simulate launch, and we practice in simulators, it's not the same - it's not even close to the same.

I did not come to NASA to make history.

For quite some time, women at NASA only had scientific backgrounds.

When you're getting ready to launch into space, you're sitting on a big explosion waiting to happen.

I think eventually private enterprise will be able to send people into orbit, but I suspect initially it's going to have to be with NASA's help.

After the Challenger accident, NASA put in a lot of time to improve the safety of the space shuttle to fix the things that had gone wrong.
