Armstrong described the lunar surface as 'beautiful.' I thought to myself, 'It's not really beautiful. It's magnificent that we're here, but what a desolate place we are visiting.'

For the future, primarily, we must educate people in science, engineering, technology and math.

For every winner, there's a loser. And that person didn't really need to lose. They just didn't understand the game plan.

All the Chinese have to do is fly around the Moon and back, and they'll appear to have won the return to the Moon with humans. They could put one person on the surface of the Moon for one day and he'd be a national hero.

The g-forces increased and I wasn't able to continue to hold the camera against the window, so I had to lay it back against my chest, but still continued to photograph the re-entry until there was no more unusual visual effects of the energy in the atmosphere.
