Yes, I see the Mobile Base System really is the shoulder of the arm. The arm is right there, like a human arm. It's really funny to look at the similarities between a human arm and the Canadian robotics arm.

Especially when I first really started to work with Kenneth and Franklin, who had been in space already. And so, they were able to talk about space and tell me a few things about how things would really happen.

So, for me, I make no difference whether I'm training with my shuttle crew or the Expedition crew. Of course, I think I want to take more care of the Expedition crew, because they're going to stay there for a long time.

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 think doing something of your life is something that you've got deep inside, whether it's to, whether you want to be an astronaut or a, whether you want to do science, or whether you want to be a movie star, or whatever.
