It's very important to know that we packed it right because it is a safety issue for coming home.

It's really a good feeling to know that we put this up there, that it's working, that all these people's plans that worked so hard came together and things fit and we've got a real space station.

We're on the same radius from the Earth, and then we start to swing around to where we're ahead of them on the velocity vector, so we come in relative to the station from this forward velocity position and dock on to the forward end of the Lab.

A lot of these things will fly in later forms on the space station themselves, or a later form of that research will, once they kind of find out some of the basics from flying it on shuttle.

I'm thrilled to be working with the Science Channel. A chance to shine a light on the wonder and exciting possibilities of science with such a smart and talented team is a dream come true for me. It's very gratifying to me personally, and it's also a way to honor my family.

I love science and that time in history when science and the humanities were the same thing.

You just can't fake chemistry.

The best museums and museum exhibits about science or technology give you the feeling that, hey, this is interesting, but maybe I could do something here, too.
