Why not plan and test the concepts for the Mars colony here on Earth? Wouldn't it make more sense to have actual people doing things they will be doing on Mars in a productive self sufficient way? There are simple ways to create a culture of self sufficiency and community strength similar to how things have been done on earth throughout history. Should it be a highly technical solution prone to many vulnerable single points of failure? Should the colony be able to survive unforeseen catastrophic events and rebuild from the ground up with no support from Earth? If you are going to Mars or plan on helping in the effort please join this club and let's get things moving.
