Mars is far more attractive as an outpost colony for earthlings than the moon is.

The universe is the way it is. It's not going to be changed by supplications.

As time goes by, I'm increasingly impressed by how very special and timely it was that we got the degree of national commitment needed to put people on the Moon. For the first time, this nation was united in trying to develop an interplanetary capability. We've been trying to repeat that situation ever since.

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

The feeling of reduced gravity and the limitations of the space suit resulted in a slow-motion movement. Perhaps not too far from a trampoline, but without the springiness and instability.

For a million dollars, the Russians would take two people, a million apiece, around the moon and back. However, stories, videos that come from the space station, and other people, are a great inspiration to young people for an exciting career field.

The way I see it, what is going to come out of the moon activities is a respect for U.S. leadership.
