When you're in a spacecraft, you need to know what things you can touch and what things you shouldn't touch!

I know: If you're looking down at Earth, you're looking through an atmosphere that has a bit of haze in many places and not just occasional clouds.

I'm sure that there are places in the deserts in Australia that could be similar to where we might want to go on Mars.

It's not easy to get human beings into orbit. So far only three nations have been able to do that, with all the resources that they put together. And I'm just a little skeptical that that's going to be done by the private sector without making use of what has been done by the government.

Nobody ever asks who was the seventh person on the Moon. The only thing they know is who's number one and who's number two. Does anybody know who the last man was?

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 want people to go into space, to orbit around the world a few times, even to stay there for 24 hours and then come back to where they took off. And I also want people with a low income to be able to do that, not only rich people.
