I think I need to continue to think and plan and marry all of the different things that we could do that make transportation in space from the earth to the space station, from the earth to the moon to space stations around the moon to visiting an asteroid.

Exploration is wired into our brains. If we can see the horizon, we want to know what's beyond.

I was saddened to learn of the passing of Leonard Nimoy, a fellow space traveler because he helped make the journey into the final frontier accessible to us all.... Indeed, there are strange new worlds to explore -- to seek out new life and start new civilizations. It is time to boldly go where no man -- or woman -- has gone before. Thanks to Leonard Nimoy and his beloved Mr. Spock, the bar has been set high for us to continue humanity's quest to probe outward in the universe.

I would rather people understand that there is a very, very fortunate American who was given the opportunity, and was in the right place at the right time to have the moment of a lifetime. My mother was born - her name was Marianne Moon. And she was born in 1903, the year that the Wright Brothers first flew.

We really didn't devote a lot of time to investigating the scariest aspects of our flight. It was more challenging and productive to concentrate on the remedies, and leave things that couldn't be solved to happen without thinking about them. There is a morbid human curiosity associated with tragic death-producing events. Though naturally, this needs to be kept in perspective.

Everyone who's been in space would, I'm sure, welcome the opportunity for a return to the exhilarating experiences there. For me, a flight in a shuttle, though most satisfying, would be anticlimactic after my flight to the moon. Plus, if I pursued a flight myself, people would think that was the reason I am trying to generate interest in public spaceflight. And that's not the purpose - I want to generate interest in long-range space exploration.

America must dream again, and have the faith to achieve the dream.
