We always had National Geographic and Astronomy magazines and Popular Mechanics lying around the house. I got interested in exploration and different parts of the world and different parts of the universe just from seeing those things around the house and the different discussions we had as a family.

My mom studied biology and my dad studied chemistry and some physics and he is a physician, but he had a very strong interest in astronomy and astrophysics and exploration in general.

To do things that are as complicated and challenging as spaceflight, you have to have all disciplines represented to get the job done.

So here in space, obviously, in microgravity, we have to use our hands to get ourselves around, to float around the modules, because our feet, we don't necessarily walk around, we just grab hand holds and move ourselves around, which means that we need our hands free to do just that.

Amazingly, I've been sort of an anomaly in the music industry. I feel like I've been able to exist as kind of a throwback artist.

A song like 'Shooting Star' - the thought process behind writing that song was that I looked around and thought, 'Wow, there's a lot of people dying at that time in the music business.'

Man lives by imagination.

I go wherever my creativity takes me.
