No, I think most astronauts recognize that the space shuttle program is very high-risk, and are prepared for accidents.

So most astronauts getting ready to lift off are excited and very anxious and worried about that explosion - because if something goes wrong in the first seconds of launch, there's not very much you can do.

NASA has to approve whatever we wear, so there are clothes to choose from, like space shorts - we wear those a lot - and NASA T-shirts.

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.

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.

The view of Earth is spectacular.

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