Buzz Aldrin doesn't think we need to go back to the Moon - that we should go straight on to Mars. I'm more on the side that says we should go back to the Moon. I think there's a lot we can utilise the Moon for scientifically.

We've been to the Moon nine times. Why would we fake it nine times, if we faked it?

Roger, Tranquility. We copy you on the ground. You've got a bunch of guys about to turn blue. We're breathing again. Thanks a lot.

I think a Moon base is not necessary to get to Mars, but I think it will be helpful. It would give you a chance to develop and mature some systems; long duration, deep space stuff; and you're close enough to get some help, via radio from Earth.

Roger. We've got you, we're go on that alarm.

Roger, we copy. It was beautiful from here, Tranquility. Over.
