But I found that being an artist and doing accurate work is very difficult.
I found I have to stay painting.
We knew it was going to be difficult to get to the moon. We didn't know how difficult.
I find color schemes that I just like and that just feel right.
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.
