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

If we go back to the moon, we're guaranteed second, maybe third place because while we are spending all that money, Russia has its eye on Mars. Landing people on the moon will be terribly consuming of resources we don't have. It sounds great - 'Let's go back. This time we're going to stay.' I don't know why you would want to stay on the moon.

Mars has been flown by, orbited, smacked into, radar examined, and rocketed onto, as well as bounced upon, rolled over, shoveled, drilled into, baked and even blasted. Still to come: Mars being stepped on.

The way I see it, commercial interests should manage a lunar base while NASA gets on with the really important task of flying to Mars.

Save the taxpayer's money by canceling the Ares 1 and V.

I think both the space shuttle program and the International Space Station program have not really lived up to their expectations.

There's a need for accepting responsibility - for a person's life and making choices that are not just ones for immediate short-term comfort. You need to make an investment, and the investment is in health and education.
