The most fun to do in the weightlessness is going down the ladder headfirst, walking on the ceiling, chasing after M&M's that you throw up into the air - they're just bouncing around all over the place and you go around like a fish eating them. I often tell kids that when you go into space and experience weightlessness, the serious adult in you gives way to the child you used to be, who had imagination, who had no bounds on what was possible.

Canada and space are a natural fit.

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.

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

New standards for safety are now in place and Canada has helped provide tools and techniques that were needed. Technologies like these are innovative and represent great achievements for us.

I'd really love to go for a fourth trip into space with maybe Mr. Duceppe and Mr. Boisclair, and I am convinced, I am convinced that after such a trip, Quebec sovereignty will no longer be an issue. Space travel affects us that much.

I would love to see the world's space programs continue toward sending humans to an asteroid or to Mars, with, of course, a full plan in place to bring them back. That excites me. And one of the things that excites me most about space is that we can go up there and put spacecraft in orbit with sensors that will help us measure the health of our planet, which is becoming particularly important. Our planet needs to be observed.
