?? As follows from all our discussions,
the biggest problem is the propulsion.
And the one-way mission has only HALF of this problem.
So you calim that having half the problem makes 
it impossible or more expensive?

I agree that the one-way outpost-building mission
will need more supplies (including a sort of factory
to build even more at the target), but I think
this additional cost will be negligible as compared with
the cost of engine/fuel needed for the way back.
The engine for a two-way mission must be made reliable 
for twice the time and for two start-cruise-stop cycles.

Agreed. But they will pay less for the one-way mission...
(Take also into account the costs of awards, medals,
and retirement funds for the return crew  ;-))
