My favourite city is Moscow, because of its history, which I find fascinating. As I learned to speak Russian, it made it even more interesting.
I've been lucky enough to fly to space twice.
I'm really looking forward to it, if you can imagine floating weightless, watching the world pour by through the big bay window of the space station playing a guitar; just a tremendous place to think about where we are in history.
We are not machines exploring the universe, we are people.
The rough and ready improvisational quality to life on board the International Space Station is reminiscent of a long trip in a sailboat: privacy and fresh produce are in short supply, hygiene is basic, and a fair amount of the crew's time is spent just on maintaining and repairing the craft.
