My quest to expand access to space began more than a decade ago, when I teamed up with Burt Rutan at Scaled Composites to build SpaceShipOne. This innovative air-launched vehicle was the world's first private spacecraft to carry an astronaut into sub-orbital space.
During that space walk there will be some repositioning of the power so that the arm can be fully controlled by the robotic station that is in the Lab.
What an incredibly proud moment as a Canadian to have the Canadian flag on the left shoulder of your space suit, looking at the Canadian logos on the robotic arm in the payload bay of the space shuttle, and there's the Orbiter Boom Sensor System, which was an extension of the Canadarm to inspect the tiles underneath the orbiter. It struck me that there were more Canadian logos in space than any other country's I saw.
When this space walk will be completed, then the arm will be fully operational and ready for the next activity that will be pretty much the testing, the first flight testing of the space station arm.
Shortly afterwards, I did a third one to repair the robotic arm of the station. This arm plays a very important role in the ongoing expansion of the station as well as in the deployment of solar panels.
I had always been interested in the space program, and I didn't know if I could be an astronaut like I'd dreamt about when I was a little kid - to me it sounded kind of silly, someone grow up to be an astronaut - but, when I was in my 20s, I thought maybe I can get a job with NASA or a contractor, do something with the space program.
My obsession with outer space is my way of being different. I make astronaut music. It takes an astronaut so long to get to space - that's how long it takes to catch up on my music.
I'll be the person using the shuttle robotic arm.
Every astronaut flew into space for a living. But while NASA has not solved the security problems, I would not put me back into a shuttle - and no other astronaut. The confidence is shaken.
It's fun to work the robotic arm in part because it's really a team effort.
On the wall of his rehabilitation room was a picture of the space shuttle blasting off, autographed by every astronaut now at NASA. On top of the picture it says, "We found nothing is impossible." That should be our motto.
I'll carry on, carry over, carry forward, Cary Grant, cash and carry, carry me back to Old Virginia, I'll even 'hari-kari' if you show me how, but I will not carry a gun!
All space exploration is risky. As an astronaut, I had to decide each and every time I went to space whether or not to risk my life for the mission.
I wanted to be an astronaut and wanted to go to space camp, but then I found out that I was too short to become an astronaut. My mom really made me believe that if I worked hard enough and if I really wanted to do it, I could do it.
Well, we have two major goals. The most important one is to get the station arm on board the station, because that's this really milestone in the space station building since from now on they will be using this arm to continue building the space station.
As a kid, I wanted to be an astronaut. And my own passion was that I wanted to be a film director. I realized that being an astronaut was not going to be an option, so I said, "Well, I'm going to be a director and do films in space."
