maybe very unlikely is fairer)
2. If you've read some of my other posts I suggested the priority was
to build SPS's before a fully blown space colony for the very reason
you give.

It would be nice - but I couldn't see us raising in the order of $5
billion in this way.

I admit some of the imagery is a bit idyllic - but he's just trying
to sell his case.
The point is the whole basis of the HF concept and particularly SPS's
is based on sound econimics and engineering. So he's embellished it
with a few pretty pictures to help sell it. This is unlike Mars
Missions whose objectives are 'exploration' or 'we'll go there
because it's there'. It's time we based space development on sound
logic instead of the forfillment of boyhood dreams dtarted by dated
science fiction.
If you read the NASA-AMES sponsored studies SP-413 and SP-428 you
will see the nitty gritty of this concept and how - in the end it
will make money. These studies were done back in the 70's just after
Apollo had finished and so the emphasis was on the colonies. Now we
are more finacially constrained the emphasis is on the SPSs
As for the asteroids, back in the 70's there were very few NEA's
known so the Moon seemd preferable, howevere there is extensive study
of processing of asteroidal material in SP-428

Can't say I have - but I get the feeling it would be somewhat biased.
Are there any papers available to read on the Mars-Direct concept?

I would feel that a great opportunity of reaping benefit for the
whole human race had been missed and a chance to start colonisation
of the rest of the Solar system. Unlike the Zubrinites who would have
missed the chance of an expensive and unproductive series of
exploratory trips.
Who's to say 30 years plus? The very first manufacturing facilities
in space could build a ship to go to Mars at the same time as SPSs
and that wouldn't be thirty years away.

Exactly - Mars,Mars,Mars - it's a big Universe you know there is more
than just Earth and Mars in it.
The HF concept addresses problems down on Earth (With SPS) as well as
opening up exploration and colonisation of the whole Solar System -
Mars included - and eventually even the Stars.
That's what annoys me about Mars proponents - to them Mars is the
centre of the Universe. They haven't got time for any other concept
or place.

That's the trouble - I can't see obtaining material from the Martian
Moons as being economical in any way. The only major Market we have
is on the Earth, Phobos and Diemos are just too far away. It would be
expensive enough to obtain materials from a NEA or the Moon
initially, without going all the way to Mars.

Obtaining materials from Deimos to LEO? Can't see it working myself.
Maybe from the Moon, but not Mars.
