A City on Mars: Reality kills space settlement dreams

This is a most excellent place for technology news and articles.
I think the far-more realistic scenario is we create a colony of robots, first for experiments, then (if possible) to build out a colony that can eventually be inhabited by humans.
If we’re going to get anything useful out of mining (other than just building material), it’s going to be incredibly sparse. I think we need to start asap working on robotic mining vehicles to wander around collecting and refining useful stuff. By the time we send people, we ought to have spent years collecting tankfuls of oxygen and water, caches of refined ores, piles of bricks and pavers (maybe even sheds/garages), maybe even sheets of crude solar cells, miles of wire.
Navigation and communication will be crucial, so we need to lead with a constellation of gps/communications satellites so no matter where you are, you know your location, can reliably contact your base, and even all back to earth. We’ll want many automated weather and seismic stations that need to send a flood of data somewhere
