NASA should start thinking about this planet.

At the end of our NASA careers, no one had a place for us in the military.

I saw the booster, not Sputnik, flying by, and I said, maybe this is the way we should be going, not just sitting back waiting for something to happen.

I don't go along with going to Moon first to build a launch pad to go to Mars. We should go to Mars from Earth orbit. We have already been to the Moon; we've already practiced.

I've always thought space station is a great name. It should be like a gas station where we go for service and supplies before heading further out.

When a man looks across a street, sees a pretty girl, and waves at her, that's not a rendezvous, that's a passing acquaintance. When he walks across the street and nibbles on her ear, that's a rendezvous!
