Maybe a hab/modules for the following:
-brick making
-medical facility
-manufacturing solar panels
-repairing misc. equipment on mars
Maybe these modules could be launched and landed without a crew? Have crews go back and forth in cycler ships and somehow connect the supply module to the cycler ship?
]]>Plus, being there are only two habs involved saves on having to build a third one, if there is one for Earth-Mars, Mars surface, and Mars-Earth, which is $$$ in the bank.
I think that the hab module on MarsDirect is too small, and a bigger one ought to be mandetory, if it takes two SDV launches instead of one or not.
