Best 4 quotes of Dafydd Williams on MyQuotes

One of the things that's really exciting from my perspective is that Canada is one of the major spacefaring nations. The list of our achievements is profound and significant, and it's not just in robotics, it's also in the life-sciences research experiments that take place on board and other space-science experiments. I'd love to see Canada go from being a major spacefaring nation in low-Earth-orbit missions to those beyond, making sure we're part of those missions to Mars - not just from a technology perspective, but sending humans into beyond-Earth orbit.

On my second space walk, I was riding the Canadarm, heading down toward the payload bay of the space shuttle, and I could see the space shuttle highlighted against the Earth in the background, and there was this black, infinite, hostile void of space. I remember looking down at the Earth and thinking, "Beneath me is a 4½-billion-year-old planet, upon which the entire history of the human species has taken place." That was an incredibly humbling moment, and I had a bit of an epiphany.

The first space walk, it's really got your attention. You know you're travelling eight times faster than a rifle bullet, and you're outside. Second space walk, you're a lot more relaxed, you're looking over your shoulder, admiring the view of Earth. What was funny about the third space walk was that mission control in Houston called and said, "Take a moment and enjoy the view".

When I was at McGill medical school, there was a writer, Ted Rosenthal, who used to write for the New York Times - tragically he died of leukemia at a very young age. He talked about how we can have an opportunity to live a lifetime in a moment, in a day, in a month, in a year - when you're confronted with the finite reality of your own existence, all these moments become lifetimes.
