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

On a standard space shuttle crew, two of the astronauts have a test pilot background - the commander and the pilot.

The space shuttle is a better and safer rocket than it was before the Challenger accident.

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

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.

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.
