Now picture Sasha floating freely in space and she wanted to go to sleep.

I'm really looking forward to it, if you can imagine floating weightless, watching the world pour by through the big bay window of the space station playing a guitar; just a tremendous place to think about where we are in history.

When we first get to space, we feel sick. Your body is really confused. You're dizzy. Your lunch is floating around in your belly because you're floating. What you see doesn't match what you feel, and you want to throw up.

When you're on one of the Caribbean islands, sometimes it's hard to picture how they fit in with the rest, but when you see them all joined together like a necklace from space, you see the natural geographic connectedness of them all.

When I did my spacewalks, it was during space station construction. So the shuttle was docked to the fledgling ISS at the time. So we would always stay tethered.

If you don't like airline food, you'll probably have the same impression of space station food. I would not fly to space for the food.
