Mike has answered this pretty well. I'd only add that, if the
proximity of Mars to the Belt turns out to be important, then a
habitat ORBITING Mars has all the proximity advantages of any habitat
ON Mars, PLUS all the advantages of being at the top of a gravity
well, continuous sunshine, access to zero-G, access to full-G, etc.
