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

The Moon was the most spectacularly beautiful desert you could ever imagine. Unspoilt. Untouched. It had a vibrancy about it and the contrast between it and the black sky was so vivid, it just made this impression of excitement and wonder.

Roger, Tranquility. Be advised there are lots of smiling faces in this room and all over the world. Over.

The only time I had what you would call life-threatening fear was when I was on the Moon. Towards the end of our stay, we got excited and we were going to do the high jump, and I jumped and fell over backwards. That was a scary time, because if the backpack got broken, I would have had it. But everything held together.

I was able to look out the window to see this incredible sight of the whole circle of the Earth. Oceans were crystal blue, the land was brown, and the clouds and the snow were pure white. And that jewel of Earth was just hung up in the blackness of space.

I'm proud to be an American, I'll tell you. What a program and what a place and what an experience.

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, 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.
