there's nothing out there. barren rocks with no ability to support life. if we dug tunnels and had 1000 trips a year to mars to bring supplies. we could have a colony underground. send workers with oxygen systems up to construct some kind of dome maybes. but it seems pretty pointless and difficult with huge possibility for everyone that goes dying there. we'd have to establish a highway where rockets are the new big rigs. i think it could be done but those with the resources are more concerned with luxury goods than expanding human civilization to another planet.
