Tiangong 1, our home in space, was comfortable and pleasant.

I had been lucky that my physiology is well suited to space training.

I've been doing Tai Chi on and off for 20 years. The fundamentals of all martial arts are the same.

I've been approached to do some things with astronauts and the preparation that astronauts go through.

I've completed half of my space training at Space City in Moscow. I love adventure, and I've been training in a centrifuge and MiG Fighter with a view to going into space and being a spokesman for space exploration!

I'll tell you, being involved in human space flight, it is an emotional endeavor. I think it brings in the highest highs and the lowest lows.

We're going to be focusing our science on things that will take us farther and longer into space. For many of those experiments, the crew members are human guinea pigs, which is fine; that's part of my job. I don't mind being a human guinea pig.

In the Astronaut Office we're never totally out of training, we always keep our hand in it. But after five years, things have changed and so it's been good to get back into the flow and relearn a lot of things.

Space travel for everyone is the next frontier in the human experience.

Welcome to President Bush, Mrs. Bush, and my fellow astronauts.
