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.

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.

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.

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.

Canada's a huge country, so to be able to unite the country through communication satellite technology or to be able to observe it through remote sensing technology from space is a natural fit for a country like Canada.

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.
