I think humans will reach Mars, and I would like to see it happen in my lifetime.

We need to begin thinking about building permanence on the Red Planet, not just have voyagers do some experiments, plant a flag and claim success. Having them go there, repeat this, in my view, is dim-witted. Why not stay there?

On Apollo 11 in route to the Moon, I observed a light out the window that appeared to be moving alongside us. It was either the rocket we had separated from, or the 4 panels that moved away when we extracted the lander from the rocket and we were nose to nose with the two spacecraft. So in the close vicinity, moving away, were 4 panels. And i feel absolutely convinced that we were looking at the sun reflected off of one of these panels.

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.

If we can conquer space, we can conquer childhood hunger.

I didn't start skiing until I was 50. My wife Lois taught me how to ski. I'm proficiently conservative.
