We have played a critical role in meeting the new safety standards. The Canadian space industry contributed new tools that make the inspection of the space shuttle possible.

I went to military college in Canada and graduated as an officer in the Navy but also as an engineer.

Through these ongoing activities and possibly in the future, a Canadian will go live and work on the International Space Station and we will continue to make Canadians proud of our achievements in space.

I like the opportunity to travel the world and work in close company with other people.

You're in orbit over the Earth. And suddenly it's very, very quiet. It's dramatic. You realize you're floating in the straps in your chair. And you take off your seat belt and float over to the window and look out, and you realize, "I'm not looking at a picture, here." I couldn't process it all. Even if I forget everything else in my life, that will stay with me, burned into my brain until the day I die.

What you aren't ready for being the first time in space - on an emotional and intellectual level - is how looking down at Earth will profoundly affect you. Over the long term, it has changed the way I think about planet Earth. When you go around the planet and look down, you think about the fact that this is the cradle of humanity, that this is a place where seven billion people, 200 countries, live side by side, that we share this place and there's nowhere else to go.

I wanted to further my education, so I went on to get a Ph.D. in electrical engineering and came back and served about ten years in the Canadian Navy as what we call a combat systems engineer.
