Unfortunately, kids are led to believe things are easier to achieve than they really are.

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

Bringing an asteroid back to Earth? What's that have to do with space exploration? If we were moving outward from there, and an asteroid is a good stopping point, then fine. But now it's turned into a whole planetary defense exercise at the cost of our outward exploration.

We could have human intelligence in orbit around Mars, building things there.
-
As a student, I wrote English reports on science fiction.
-
Weve got to go [back to the moon]. But we dont want to stay too long. ... The ultimate goal is Mars.
-
Fear, to people who have been in aviation and combat (such as) fighter pilots ... is something you learn how to deal with and set aside, ... It's a very disabling emotion. You want to be alert as you possibly can.
-
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.
-
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.
-
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.
-
I've led a life of such structured discipline and always had a goal in mind of knowing what I was doing, from West Point to the Air Force combat, MIT, looking for new things to study and get involved in. And then I got into the space program, and how disciplined can you get?
-
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.

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.
-
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.
-
Having walked on the Moon, I know something about what we need to explore, really explore, in space.
-
Absolutely the United States should lead in space, for the survival of the United States. It's inspiring for the next generation. If we lose leadership, then we'll be using Chinese capability to inspire Americans.
-
I want to keep on the move, keep stimulated and challenged.
-
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 feel we need to remind the world about the Apollo missions and that we can still do impossible things.
-
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.
-
When I was a little kid, we only knew about our nine planets. Since then, we've downgraded Pluto but have discovered that other solar systems and stars are common. So life is probably quite prevalent.

History gets reinterpreted as time goes on. Many times, the participants are lost in the retelling of the story.

We feel that this stands as a symbol of the insatiable curiosity of all mankind to explore the unknown.
