I found I have to stay painting.

It seems farther away now because there are no rockets getting there. Nobody is going.

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.

We knew it was going to be difficult to get to the moon. We didn't know how difficult.

Test pilots have a litmus test for evaluating problems. When something goes wrong, they ask, "Is this thing still flying?" If the answer is yes, then there's no immediate danger, no need to overreact.

But I found that being an artist and doing accurate work is very difficult.

One of the great things about the universe is that it's fair.
