BIT: Space stuff...

The Titanium? yes, considering how many spacecraft structures are build using titanium, titanium steel, etc. Only problem is, you'd have to ship carbon up from earth...

For the big habitats, you have a few options. Metals refined on Luna would be cheaper than ones from Earth as you're shipping them up a shallower gravity well. Another option would be to snag a nickel-iron NEA, park it at L-4 or L-5, and use it to make a Cole Habitat. (And who hasn't wanted to inflate an asteroid like a 5 billion ton stainless-steel balloon? )

I could see a whole industry coming out of people doing just that, and possibly even a frontier type civilization out in the astroid belt- after a looong while, that is.

The hard thing to find out in space would probably be carbon.

Martian atmosphere is CO2, so is Venus.
