"I have no intention of selling any more of the historical Apollo 11 items in my possession for the remainder of my life. I intend to pass a portion of these items on to my children and to loan the most important items for permanent display in suitable museums around the country."

"Mars is there, waiting to be reached."

"Neil Armstrong was the first man to walk on the moon. I am the first man to piss his pants on the moon."

"I believe that every human has a finite number of heart-beats. I don't intend to waste any of mine running around doing exercises."

"Monumental achievements by humanity should be done by major organizations as much together as possible."

"To send humans back to the moon would not be advancing. It would be more than 50 years after the first moon landing when we got there, and we'd probably be welcomed by the Chinese. But we should return to the moon without astronauts and build, with robots, an international lunar base, so that we know how to build a base on Mars robotically."

"I came to dedicate my life to opening space to the average person and crafting designs for new spaceships that could take us far from home. But since Apollo ended, such travels were only in our collective memory."

"Everyone should take their hats off to Neil Armstrong. He is a humble guy who doesn't wave his own flag."

"Exploring and colonizing Mars can bring us new scientific understanding of climate change, of how planet-wide processes can make a warm and wet world into a barren landscape. By exploring and understanding Mars, we may gain key insights into the past and future of our own world."

"We can't start over and develop a Saturn 5-type vehicle from scratch."

"We had this whole big beautiful place for discovery, and all we could think to do with it was wipe out everything that made it worth discovering."

"Simply put, I was without a career, and I was feeling the aftereffects of it all. As always, I was standing by, ready for liftoff, but I needed to realign my direction and find a new runway."

"I am definitely not rich."

"I don't watch 'American Idol,' but I wouldn't call it 'undignified.'"

"Do we really need these big, gigantic, heavy rockets? What if we launch a rocket that's empty, and its sole purpose is to act as a source of fuel on the Moon? Who should build that? Well, I think the U.S. should build that."

"During the divorce process, I lived alone and tended to get extremely down on myself."

"I failed music when I was a teenager."

"A hybrid human-robot mission to investigate an asteroid affords a realistic opportunity to demonstrate new technological capabilities for future deep-space travel and to test spacecraft for long-duration spaceflight."

"When President Kennedy took office, I was in the midst of my education."

"I don't go through life verbalizing what I feel."

"Us reaching the moon convinced Gorbachev and other leaders that the Soviet Union couldn't compete with the U.S., so they revised their agenda. But people have short memories."

"I shot down two airplanes in Korea, so I wasn't a slouch."

"I think we need to move to the moons of Mars and learn how to control robots that are on the "surface". It's not the impatient way of getting there, but Mars has been there a long time."

"There's no guarantee that the United States will be around 200 years from now."

"Human rights problems will always exist for years to come, but maybe they'll lessen somewhat."

"I don't think we're going to build a 50-person spacecraft or a 100-person spacecraft."

"Save the taxpayer's money by canceling the Ares 1 and V."

"When the time comes to start building deep space transports and refueling rocket tankers, it will be the commercial industry that steps up, not another government-owned, government-managed enterprise."

"Landing in the ocean and waiting for the Navy to come alongside and haul you out of the drink is what space capsules require. And after the capsule is recovered, it would take weeks for the ship to return to port."

"One of the major problems with long-term deep space human flight is the requirement for radiation shielding."

"Mars has a bit of air pressure; maybe we can build up that atmosphere to be a bit more accommodating to humans."

"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."

"My father's an early aviator, and my first flight was with him at age two. Now, despite the fact that I got sick on the flight, I still enjoyed it, I believe."

"We could have human intelligence in orbit around Mars, building things there."

"Look at what Silicon Valley has done - the advance of computers."

"In Mars, we've been given a wonderful set of moons... where we can send continuous numbers of people."

"I grew up in a country that I thought was special. And it was."

"'Anthony and the Magic Picture Frame' tells it like it really was in America's early space program - the adventure, the risks, and the rewards."

"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."

"If you want poets in space, you'll have to wait."

"You can never tell when a commercial space venture will suddenly become viable."

"Like actors and writers who are on and off again in terms of employment, I had a very unstructured life."

"You are not going to change the minds of people who are looking for attention."

"I do celebrity ski races all over the world."

"Growing up, I was fascinated with Buck Rogers' airplanes. As I began to mature in World War II, it became jets and rocket planes. But it was always in the air."

"I realize that my life is not the common ordinary person."

"I inherited depression from my mother's side of the family."

"I am not sure about Bill Nelson. I haven't heard him say, 'Let's junk the NASA plan to send humans to the moon.' He's not about to say that. That would not be very popular."

"Russia perhaps is still entertaining the possibility that the moons of Mars might have access to ice or water."

"Astronauts working for the government will always need to be either pilots or mission specialists. Those who want to be pilots should have military experience - ideally, a test pilot background."
