It is a challenge to have your launch date slip continuously.

Canada has made a strong commitment as a partner in the International Space Station and, like the other partners, wishes to see the assembly of this unique orbiting laboratory continue.

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

In 1983, NASA invited Canada to fly three payload specialists, in part because we had contributed the robotic arm that is used on the shuttle.

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 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.
