Six out of seven times we landed successfully [on the Moon]. I wanted to be a part of that and I was a part of that, so my personal feeling is of great gratefulness for having somehow been in a position to have been given the opportunity to be on that first landing. That's a marvelous experience for a little kid that grew up in New Jersey. So I'm very thankful, and I asked the whole world to give thanks once we successfully landed.

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

Weve got to go [back to the moon]. But we dont want to stay too long. ... The ultimate goal is Mars.
-
We need to have people up there who can communicate what it feels like, not just pilots and engineers.
-
As someone who flew two space capsules and twice landed in the ocean, I can attest from personal experience how much logistics work is needed to get you home.
-
I think the climate has been changing for billions of years.
-
Exploring Mars is a far different venture from Apollo expeditions to the moon; it necessitates leaving our home planet on lengthy missions with a constrained return capability.
-
We could have human intelligence in orbit around Mars, building things there.
-
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.

As a student, I wrote English reports on science fiction.

I was the first Navy, Marine or Air Force person who had been an astronaut to return back to the Air Force. I had certain expectations about what would be a reasonable and desirable position to be assigned to after my years of service.

Having walked on the Moon, I know something about what we need to explore, really explore, in space.
-
America's can-do spirit cast a warm glow across nations and cultures, generating more goodwill and support for our country's ideals and causes than had otherwise been possible.

The decision to go to the moon is now appreciated and associated with President Kennedy's speech, but somebody else had told him it was a good idea. It turned out to be a good commitment, but it was a unique situation.

The first human beings to land on Mars should not come back to Earth. They should be the beginning of a build-up of a colony/settlement, I call it a 'permanence'.
-
People communicate in Twittering ways. I've learned how to do that.
-
I want to keep on the move, keep stimulated and challenged.
-
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.

Mars is much closer to the characteristics of Earth. It has a fall, winter, summer and spring. North Pole, South Pole, mountains and lots of ice. No one is going to live on Venus; no one is going to live on Jupiter.

There's a tremendously satisfying freedom associated with weightlessness. It's challenging in the absence of traction or leverage, and it requires thoughtful readjustment. I found the experience of weightlessness to be one of the most fun and enjoyable, challenging and rewarding, experiences of spaceflight. Returning to Earth brings with it a great sense of heaviness, and a need for careful movement. In some ways it's not too different from returning from a rocking ocean ship.

The surface of the moon is like nothing here on Earth! It's totally lacking any evidence of life. It has lots of fine, talcum-powderlike dust mixed with a complete variety of pebbles, rocks, and boulders. Many pebbles, fewer rocks, and even fewer boulders naturally make up its surface. The dust is a very fine, overall dark gray. And with no air molecules to separate the dust, it clings together like cement.

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.
-
I want to reach a new generation. That's why I am Twittering now. I have a BlackBerry, an iPhone and a Mac.

Returning to the Moon with NASA astronauts is not the best usage of our resources. Because OUR resources should be directed to outward, beyond-the-moon, to establishing habitation and laboratories on the surface of Mars that can be built, assembled, from the close-by moons of Mars.
