Yes. And He wrote on 1999-05-24:
Re: The discussion of mining minerals and ores on Mars
(differentiated core, but easy digging) I'm afraid the dream
won't work for a simple reason. There's a better source of
raw materials just floating around a little farther out in the
solar system.
Evidence from meteorites is strong
that there was a differentiated body that got broken up
~600 million years ago, and that that's what many asteroids
may be from. If so, you don't have to drill at all: you just
find the right asteroid and harvest the whole thing.*
For more on this, see MINING THE SKY, by my pal, U or
Arizona Prof John S. Lewis. He has some more books, too.

* Some suggest this was one of 3 bits of evidence that
the solar system was visited in that time frame. The other
two were the Cambrian "explosion" of life ("somebody flushed
a toilet"), and the claim that the age-distribution of ore-bodies
of certain minerals that might be of interest to advanced
civilizations shows a distinct drop for ages >600 million years.
So I think it's fair game to add His scientific speculations into
His fiction :-)

But they did: there are Galactic Library references to Earth - only they

Is this a real problem? We are recording dates, not computing periods.

No, as in "2489-May : Streaker flees to Kithrup" :-P
