The space industry is developing and delivering benefits that tie into our immediate needs and priorities here on Earth-for example, medical and materials research, and satellite communications.

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

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'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.

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.
