This would not be an expedition but more the establishment of a permanent base that will continue to function and grow indefinitely.
Lets plant a strong base to be the foundation of our very first human presence there.
It is only self defeating if we endanger an expedition by leaving out key figures that could make a big difference. Rather than one or two large habitats it should be a network of inhabitable spaces providing for redundancy if part of the structure should fail for some reason. With people and equipment redundancy is the best insurance of success. Safety lies in numbers. Safety lies in numbers.
