Very Expensive?
It is all wonderful news that humans are returning to the Moon and we may have robotic humanoids on Mars in the next five years, but as for colonization apart from the scientific, that may still be a hundred years away yet, since it will be very expensive to maintain!

What holds us back now is mental health issues that were experienced on the International space station, being dealt with on long duration flights and how will we take to living on another world, with many moral questions too as to child birth and death!
