You are not going to change the minds of people who are looking for attention.

When you're in a spacecraft, you need to know what things you can touch and what things you shouldn't touch!

America can take man to the moon, and America can take men to Mars - and beyond.

I don't watch 'American Idol,' but I wouldn't call it 'undignified.'

Exploring Mars is a far different venture from Apollo expeditions to the moon; it necessitates leaving our home planet on lengthy missions with a constrained return capability.

Heavy lifting doesn't need to be heavy spending if we do the job right.

On Apollo 11 in route to the Moon, I observed a light out the window that appeared to be moving alongside us. It was either the rocket we had separated from, or the 4 panels that moved away when we extracted the lander from the rocket and we were nose to nose with the two spacecraft. So in the close vicinity, moving away, were 4 panels. And i feel absolutely convinced that we were looking at the sun reflected off of one of these panels.
