There is a sunrise or a sunset from space every 92 minutes so there is an incredible amount of beauty to see from up there.

Doing a space walk. It is one of the most rare human experiences. To leave your spaceship and go outside, so that you are alone in the universe with Earth distant and the universe around you. That is amazing.

My favourite city is Moscow, because of its history, which I find fascinating. As I learned to speak Russian, it made it even more interesting.

The Moon has given us months, tides and a destination that ever-beckons. It's time we build a rocket and go to stay.

No one ever accomplished anything great sitting down.

For the last several years and culminating in six months in orbit next year, I've been training for my third space flight. This one is almost in a category completely different than the previous two, specifically to live in on the space station for six months, to command a space ship and to fly a new rocket ship.

In my experience, fear comes from not knowing what to expect and not feeling you have any control over what’s about to happen. When you feel helpless, you’re far more afraid than you would be if you knew the facts.
