Once you've been first, it cannot be done again. Not by you, not by anyone else.

My favourite thing to do on this planet is to scuba dive.

I felt pretty confident in relieving myself, since I had the urge.

I think the public needs to be reminded just how much inspiration and intention was given throughout the world to be bold, to send human beings to the moon in the '60s and the '70s. It's important now to bring together the nations that weren't able to do it then and help them do it. We need to move forward.

The life expectancy of people going to Mars may be decreased by the higher level of radiation that they receive.

Trips to Mars, the Moon, even orbit, will require that we provide astrotourists with as many comforts from home as possible, including paying each other.

Over the years, I think I've matured in my spiritual evolution and development to understand a bit more than the narrow religious thinking - to move beyond that through a sort of perfection of the grandiose nature of the universe, and how perfect it is it in its sense and how satisfied we should all be in our place in that.
