No aeroplane you've ever gotten into had less than thousands of flights before they took their first passenger. Because vehicles are unsafe at first.

Every single thing that you learn really just gives you more comfort. It's something I counsel kids all the time: if someone is willing to teach you something for free, take them up on it. Do it. Every single time. All it does is make you more likely to be able to succeed. And it's kind of a nice way to go through life.

One place that I looked at a lot from space and which looks alluring is New Zealand, especially the North Island. It's a big broad valley with a river flowing through it, and you can see the wine-making dryness of the land.

To be one of the world's top space robotic arm operators is a necessary skill for an astronaut, but it doesn't have much carry-over.

I've raised three kids: my wife and I have three kids. I've observed through direct contact the adults they are now is partially the product of where they came from and what we did. With them growing up, but partially how they were wired at birth.

I've put a lot of my life into making it possible to fly in space at all.

In the astronaut business - the shuttle is a very complicated vehicle; it's the most complicated flying machine ever built. And in the astronaut business, we have a saying, which is, 'There is no problem so bad that you can't make it worse.'

Nothing focuses your mind quite like flying a jet. That's one reason NASA requires that astronauts fly T-38s: it forces us to concentrate and prioritize in some of the same ways we need to in a rocket ship.

In the Soyuz, the little Russian capsule, you can actually hear the banging of the big shield, the big heat shield on the bottom, as it slowly erodes away from the heat and pieces of it fly off like sparks across your window, and it's an interesting thing to ride through, you know.

It's a really big deal to do a spacewalk. It's much riskier than staying indoors. It's complex. It uses up a lot of the precious resources onboard. It uses up oxygen. It uses up carbon dioxide scrubbers.

Cynicism is the easiest of all reactions, right? But it's also so disappointing and self-defeating.
-
While on the space station, I kept up with news a couple of ways - Mission Control sent daily summaries, and I would scan headlines on Google News when we had an Internet connection, which was about half the time.
-
So without that Canadian invention we were grounded. And so that was a really important and key part of the mission and Canadians should take real pride in it.
-
I've had a chance to fly a lot of different airplanes, but it was nothing like the shuttle ride.
-
Although simulators are great for building step-by-step knowledge of a procedure, the worst thing that can happen in a sim is that you get a bad grade on your performance.

I've been so lucky to have done two spacewalks. If you looked at your wristwatch, I was outside about 15 hours, which is about 10 times around the world. And, you know, there's a whole time dilation, distortion thing.

You should have a fear of some things. That doesn't mean it incapacitates you from your ability to figure out a way to deal with it.

The International Space Station is a phenomenal laboratory, an unparalleled test bed for new invention and discovery. Yet I often thought, while silently gazing out the window at Earth, that the actual legacy of humanity's attempts to step into space will be a better understanding of our current planet and how to take care of it.

The best simulator for spacewalking is underwater - it allows full visuals and body movement in 3D. Virtual reality is good, too, and has some advantages, like full Station simulation, not just part. Like all simulators, they have parts that are wrong and misleading: an important thing to remember when preparing for reality.

In the late '60s, I was seven, eight, nine years old, and what was going on in the news at that time that really excited a seven, eight, nine year old boy was the Space Race.
