The launch of a space shuttle can still make you weep with amazement and wonder, if you happen to be watching it.

If we're going to complete the space station, we're going to need the shuttle. It's going to take a lot of resources.

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.

We hope to launch a Personal Satellite Assistant in about two years aboard a space shuttle and in about three years aboard the International Space Station. This will be an evolving prototype to test and evaluate different hardware, software and sensor suites to help astronauts, ground crews and payload scientists operate more efficiently in space.

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