I suggest that going to Mars means permanence on the planet - a mission by which we are building up a confidence level to become a two-planet species.

By refocusing our space program on Mars for America's future, we can restore the sense of wonder and adventure in space exploration that we knew in the summer of 1969. We won the moon race; now it's time for us to live and work on Mars, first on its moons and then on its surface.

I'm in favor of changing the destination of humans. There are a lot of manned missions that can be done, but not in the direction of the moon.

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

We'll get to the details of what's around here, but it looks like a collection of just about every variety of shape - angularity, granularity, about every variety of rock.... The colors - well.... There doesn't appear to be too much of a general color at all; however, it looks as though some of the rocks and boulders are going to have some interesting colors to them. Over.

Everyone who's been in space would, I'm sure, welcome the opportunity for a return to the exhilarating experiences there.

I think the American Dream used to be achieving one's goals in your field of choice-and from that all other things would follow. Now, I think the dream has morphed into the pursuit of money: Accumulate enough of it, and the rest will follow. We've become more materialistic. For balance, I think we need to get back to idealism and patriotism, but also be realistic with our monetary goals.
