We need to make science cool again.

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.

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

On both of my flights, everything went very well.

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.

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

We can see cities during the day and at night, and we can watch rivers dump sediment into the ocean, and see hurricanes form.
