As the centuries unfold, millions of artists will live on the moon and paint the moon and Mars as we go out into the universe.
But I found that being an artist and doing accurate work is very difficult.
I can remember walking on the moon. 
It's hard not to be excited when you're going to find a way to land on the moon. 
It seems farther away now because there are no rockets getting there. Nobody is going. 
Eventually there are going to be cities in space. 
But I'm the only one who can paint the moon, because I'm the only one who knows whether that's right or not. 
Frequently on the lunar surface I said to myself, 'This is the Moon, that is the Earth. I'm really here, I'm really here!' 
The moon is very rugged.
